Abstract
Description
本發明係關於一種電荷消散傳導裝置,其中靜電電荷係因使用旋轉設備而產生。The present invention relates to a charge dissipation conduction device in which an electrostatic charge is generated by using a rotating device.
旋轉設備之適當維護並不容易,尤指電動馬達,因其相當的設備負荷循環、服務係數與設計等之降低,及於運轉廠內之備用旋轉設備之缺乏等,故使其之維護等並不容易。此對電動馬達、機械工具轉軸、紙漿設備滾輪、鋁製軋機、蒸氣驟冷泵,及其他利用有相當沾汙物而會影響潤滑之設備等而言,更是顯著。Proper maintenance of rotating equipment is not easy, especially for electric motors, because of the equivalent equipment load cycle, service factor and design reduction, and the lack of spare rotating equipment in the operating plant, so it is maintained and so on. not easy. This is especially true for electric motors, machine tool shafts, pulp equipment rollers, aluminum mills, steam quench pumps, and other equipment that can affect lubrication with considerable contaminants.
已知多種不同之軸封裝置可用於保護軸承環境之整體性。此些裝置包括如:橡膠密封唇、間隙迷宮式密封,及磁吸密封等。密封唇或其他接觸式軸封件往往會因磨損而失效,且已發現其易使水氣及其他沾汙物侵入至操作環境中之潤滑油儲存部,甚至在尚未造成密封失效前,即使介於轉子與定子間之介面,於密封之徑向末端受到沾汙物或潤滑劑之汙染。軸承失效與損害之問題,對利用變頻驅動(VFD)電動馬達而言,將因連接電力係連接至VFD控制馬達而更為嚴重。往往因使用VFD而造成如此。A variety of different shaft seals are known to protect the integrity of the bearing environment. Such devices include, for example, rubber sealing lips, gap labyrinth seals, and magnetic seals. Sealing lips or other contact shaft seals tend to fail due to wear and have been found to easily infuse moisture and other contaminants into the lubricating oil reservoir in the operating environment, even before the seal has failed. The interface between the rotor and the stator is contaminated by contaminants or lubricants at the radial ends of the seal. The problem of bearing failure and damage is more serious for the use of variable frequency drive (VFD) electric motors, which are connected to the VFD control motor due to the connected power system. This is often the case with VFDs.
VFD係藉由轉換正弦線交流(AC)電壓至直流(DC)電壓,並再將其轉回變頻之脈衝寬度調變(PWM)AC電壓,以控制馬達之速度,此些脈衝之切換頻率範圍係介於1kHZ至20kHz,且其亦稱為「載波頻率」。電壓差與時間差之間之比例(ΔV/ΔT),可產生所謂之介於馬達定子與轉子之間之寄生電容,其亦包含於轉軸上之電壓。若電壓感應產生於該軸上,其係稱為「共模電壓」或「軸電壓」,當此電壓到達一足夠程度時,其可藉由軸承以放電至地面。而經由此方式透過馬達軸承流向地面之電流,則稱為「軸承電流」。The VFD controls the speed of the motor by switching the sinusoidal alternating current (AC) voltage to the direct current (DC) voltage and then switching it back to the variable frequency pulse width modulation (PWM) AC voltage. It is between 1kHZ and 20kHz and is also called "carrier frequency". The ratio between the voltage difference and the time difference (ΔV/ΔT) produces a so-called parasitic capacitance between the stator and rotor of the motor, which is also included in the voltage on the shaft. If voltage induction is generated on the shaft, it is called "common mode voltage" or "axis voltage". When this voltage reaches a sufficient level, it can be discharged to the ground by bearings. The current flowing through the motor bearing to the ground in this way is called "bearing current".
會造成軸承電流之產生之原因有許多,包括電壓脈衝於VFD中之過衝、馬達磁性電路之非對稱、供電不均,及瞬態工況與其他原因等。任何此些情況之單獨或同時發生,皆會造成軸承電流自馬達軸產生之。There are many reasons for the generation of bearing current, including overshoot of voltage pulses in VFD, asymmetry of motor magnetic circuits, uneven power supply, transient conditions and other reasons. Any such situation occurs separately or simultaneously, causing bearing current to be generated from the motor shaft.
當累積於轉子上之軸電壓超過馬達軸承潤滑劑之介電量時,電壓將會以較小脈衝透過軸承放電至地面上。於放電後,電壓將又再累積於軸體上,並再次循環之。此不規律且常發生之放電係造成放電加工(EDM)效應,此效應會使軸承之轉動元件與滾道產生凹洞現象。初期時,此些放電會造成「霜化表面」或「磨砂表面」現象於此些元件之表面上。長時間下來,此些表面粗糙將會造成於軸承上之凹痕,亦稱為「凹槽化」,此也是一種可看出軸承已相當嚴重損壞之徵兆。若繼續使用,此粗糙化現象將造成軸承完全地失效。When the shaft voltage accumulated on the rotor exceeds the dielectric charge of the motor bearing lubricant, the voltage will be discharged to the ground with a small pulse through the bearing. After discharge, the voltage will accumulate on the shaft again and circulate again. This irregular and often occurring discharge causes an electrical discharge machining (EDM) effect that causes a concave cavity in the rotating elements of the bearing and the raceway. Initially, these discharges can cause "smoothed surfaces" or "matte surfaces" to appear on the surface of these components. Over time, these rough surfaces will cause dents on the bearings, also known as "grooves", which is a sign that the bearings have been severely damaged. If used continuously, this roughening will cause the bearing to completely fail.
就最外在之應用上而言,其無疑增加了成本、複雜度與暴露於外在環境等因素之考量。隔離式軸承可提供一於內部設計上之方案,以將所述允許電流經過軸承到達地面之路徑完全阻絕。然而,隔離式軸承之安裝並無法防止軸電壓,換言之,其仍會繼續透過較低阻抗之路徑,以通往地面。因此,隔離式軸承並無法有效地解決問題,尤其當低阻抗路徑係通過驅動負載時。綜上,先前技術並未教導一種內在式、低磨損之方式或裝置,以有效地將軸電壓接地,並可防止軸承之放電加工造成軸承之永久損害與無效。For the most external applications, it undoubtedly increases the cost, complexity and exposure to external factors. The isolated bearing provides an internal design solution that completely blocks the allowable current through the bearing to the ground. However, the installation of the isolated bearing does not prevent the shaft voltage, in other words, it will continue to pass through the lower impedance path to the ground. Therefore, isolated bearings do not effectively solve the problem, especially when the low impedance path is driven through the load. In summary, the prior art does not teach an intrinsic, low-wearing manner or device to effectively ground the shaft voltage and prevent permanent damage and ineffectiveness of the bearing due to electrical discharge machining of the bearing.

The bearing isolator 10, the explosion-proof current shunt device 10', the current shunt device 11, the CDR 40, 200', the radial CDR 80, the curved CDR 80a, the polycyclic CDR 100, the adaptive CDR 160 and the capture CDR 200 And the like, which may be used in or alternated with the shaft seal and/or bearing isolation when describing the general configuration and/or corresponding components, embodiments, features, functions, methods, and/or structural materials. The device 10 is not particularly limited unless the specification clearly indicates otherwise.
於一實施例中,電流分流裝置可為一用於旋轉設備上之裝置,該旋轉設備可傳導與傳遞,並引導累積之軸承電流至地面上。於另一實施例中,此電流分流裝置係有利於一電流分流環設於軸承隔離器之定子內。導電段可由金屬或非金屬固體經加工或模具所製成。就操作環境與金屬特性而言,雖然許多不同之相容材質皆係可能的,如銅、金、碳等,惟鋁基於具有較佳之導電性、強度、耐蝕與耐磨性等,其係較佳之金屬選擇。In one embodiment, the current shunting device can be a device for rotating the device that conducts and transmits and directs the accumulated bearing current to the ground. In another embodiment, the current shunting device facilitates a current shunting ring disposed within the stator of the bearing isolator. The conductive segments can be fabricated from metal or non-metallic solids or machined. In terms of operating environment and metal properties, although many different compatible materials are possible, such as copper, gold, carbon, etc., aluminum is based on better conductivity, strength, corrosion resistance and wear resistance. Good metal choice.
目前已知當軸承隔離器內之轉子與定子係由銅材質所製成時,其可具有較佳之電荷消散特性。於一利用銅金屬特性之實施例中,符合規格932之銅材質係可採用的(亦稱為932000或「軸承銅」)。因此銅材質之極佳荷重能力與防磨特性,其可用於軸承與軸承隔離器上。此軸承銅亦具有良好之加工特性,且具有防多種化學物之特性。所述之銅材質因其相對較小之電阻(85.9 ohms-cmil/ft @ 68 F 或 14.29 microhm-cm @ 20 C)及高導電性(12% IACS @ 68 F 或 0.07 MegaSiemens/cm @ 20 C),故其較於普遍採用之避雷針,具有更良好之軸電壓集結特性It is currently known that when the rotor and stator in the bearing isolator are made of copper, they can have better charge dissipation characteristics. In the embodiment using copper metal characteristics, a copper material conforming to the specification 932 can be used (also referred to as 932000 or "bearing copper"). Therefore, the copper material has excellent load capacity and anti-wear properties, which can be used on bearings and bearing isolators. This bearing copper also has good processing characteristics and is resistant to many chemicals. The copper material is relatively small (85.9 ohms-cmil/ft @ 68 F or 14.29 microhm-cm @ 20 C) and highly conductive (12% IACS @ 68 F or 0.07 MegaSiemens/cm @ 20 C) ), so it has better shaft voltage aggregation characteristics than the commonly used lightning rods.
於電流分流裝置與軸承隔離器之另一實施例中,其可改善由通常安裝於馬達殼體之外部之軸刷上之電荷消散特性。從過去之試驗可知,當軸承隔離器具有同心圓之電流分離器固設於軸承隔離器中時,皆可實質上減少軸電壓及放電加工效應。將電流分流裝置與軸承隔離器直接置放,亦可改善透過一簡易殼體與導電元件之組合之接地導電。In another embodiment of the current shunting device and the bearing isolator, it can improve the charge dissipation characteristics of the shaft brush that is typically mounted to the exterior of the motor housing. From past experiments, it can be seen that when the bearing isolator has a concentric circular current separator fixed in the bearing isolator, the shaft voltage and the electric discharge machining effect can be substantially reduced. Direct placement of the current shunt device and the bearing isolator also improves grounding conduction through a combination of a simple housing and conductive elements.
於另一實施例中,電流分流裝置可設有電動馬達,以旋轉具有軸承隔離器之設備,進而保持潤滑劑、防止沾汙物,及傳導與傳遞軸電流至地面。In another embodiment, the current shunting device can be provided with an electric motor to rotate the device with the bearing isolator to retain lubricant, prevent contaminants, and conduct and transfer shaft current to the ground.
於電流分流裝置與軸承隔離器之另一實施例中,其設有軸承隔離器以令旋轉設備保持潤滑劑、防止沾汙物,及傳導靜電放電(軸電壓),以增加軸承操作壽命。In another embodiment of the current shunting device and the bearing isolator, a bearing isolator is provided to maintain the lubricant, prevent contamination, and conduct electrostatic discharge (shaft voltage) to increase bearing operating life.
於電流分流裝置之另一實施例中,其設有可有效引導電荷由軸體傳導至馬達殼體上之裝置,並可避免電荷經由軸承而傳遞至地面。In another embodiment of the current shunting device, it is provided with means for effectively directing charge conduction from the shaft to the motor housing and to prevent charge transfer to the ground via the bearing.
關於電流分流裝置、電流分流環,及/或軸承隔離器之其他實施例、目的、優點、特徵及/或功能等,皆可透過以下說明容及圖式獲得更詳細之解說。Other embodiments, objects, advantages, features and/or functions of the current shunting device, the current shunting ring, and/or the bearing isolator can be obtained in more detail by way of the following description.

定子20大致上可包含一定子主體22及多個自其延伸出之軸向及/或徑向突出部,及/或多個設於其內之軸向及/或徑向凹槽,詳如下。於一實施例中,如圖2及3所示,定子20可固設於設備殼體16上,其並具有一O形環18形成介於其中之密封。The stator 20 may substantially include a certain sub-body 22 and a plurality of axial and/or radial protrusions extending therefrom, and/or a plurality of axial and/or radial grooves disposed therein, as follows . In one embodiment, as shown in FIGS. 2 and 3, the stator 20 can be secured to the device housing 16 and has an O-ring 18 forming a seal therebetween.
轉子30大致上可包含一轉子主體32及多個自其延伸出之軸向及/或徑向突出部,及/或多個設於其內之軸向及/或徑向凹槽,詳如下。於所示之實施例中,一定子軸向突出部26與一轉子軸向凹槽39配合作用,及一轉子軸向突出部36係與一定子軸向凹槽29配合作用,以形成介於軸承隔離器10與外界環境間之迷宮式通道。轉子30可固設於軸體14上,並可隨其轉動之。O形環18可用於形成介於其間之密封。密封件17可定位於介於其間之內部介面上之定子20與轉子30之間,以防止沾汙物自外界環境侵入至軸承隔離器10之內部,並可同時利於將潤滑劑保持於軸承隔離器10之內部。The rotor 30 can generally include a rotor body 32 and a plurality of axial and/or radial projections extending therefrom, and/or a plurality of axial and/or radial grooves disposed therein, as follows . In the illustrated embodiment, the stator axial projection 26 cooperates with a rotor axial groove 39, and a rotor axial projection 36 cooperates with a certain axial axial groove 29 to form a A labyrinth passage between the bearing isolator 10 and the outside environment. The rotor 30 can be fixed to the shaft body 14 and can be rotated therewith. O-ring 18 can be used to form a seal therebetween. The sealing member 17 can be positioned between the stator 20 and the rotor 30 on the inner interface therebetween to prevent intrusion of contaminants from the external environment into the interior of the bearing isolator 10, and at the same time facilitate the maintenance of the lubricant in the bearing isolation. The inside of the device 10.
如圖2及3所示之軸承隔離器10之實施例中,定子徑向突出部28設有外側凹槽於定子20上,以用於收集沾汙物。第一軸向介面間隔34a可形成於定子徑向突出部28之徑向外表面與轉子徑向突出部38之徑向內表面之間。第一徑向介面間隔34b可形成於定子軸向突出部26之軸向外表面與轉子軸向突出部39之軸向內表面之間。具有轉子徑向突出部38之轉子軸向突出部36可經組態,而可配設至定子軸向凹槽29中,以提供介於定子20及轉子30之間之另一軸向介面間隔。In the embodiment of the bearing isolator 10 as shown in Figures 2 and 3, the stator radial projections 28 are provided with outer grooves on the stator 20 for collecting contaminants. The first axial interface spacing 34a can be formed between the radially outer surface of the stator radial projection 28 and the radially inner surface of the rotor radial projection 38. The first radial interface spacing 34b can be formed between the axially outer surface of the stator axial projection 26 and the axially inner surface of the rotor axial projection 39. The rotor axial projection 36 having the rotor radial projection 38 can be configured to be disposed into the stator axial groove 29 to provide another axial interface spacing between the stator 20 and the rotor 30. .
如圖所示之軸承隔離器10之實施例中,轉子徑向突出部38(鄰近於轉子軸向外表面33)係徑向延伸超過定子軸向突出部26之主直徑。此設計可使轉子30環繞定子軸向突出部26。此結構於美國專利第6,419,233亦有詳細說明,並於此作為本文之參考文獻。此徑向延伸部係於此所揭露之軸承隔離器10之重點設計特徵之一。第一軸向介面間隔34a所具有之軸向方位,此設計可控制沾汙物進入至軸承隔離器10之內。藉由減少或消除沾汙物之功效,可進而增強軸承隔離器10、軸承12及導電段46其使用年限與性能。第一軸向介面間隔34a之開口係面向後並朝向設備殼體16,並係遠離於沾汙物之流向,因此,沾汙物或冷卻流體通常係經引導以沿軸體14之軸,並朝向設備殼體16之流向。In the illustrated embodiment of the bearing isolator 10, the rotor radial projection 38 (adjacent to the rotor axial outer surface 33) extends radially beyond the major diameter of the stator axial projection 26. This design allows the rotor 30 to surround the stator axial projection 26. This structure is also described in detail in U.S. Patent No. 6,419,233, the disclosure of which is incorporated herein. This radial extension is one of the key design features of the bearing isolator 10 disclosed herein. The first axial interface spacing 34a has an axial orientation that controls the entry of contaminants into the bearing isolator 10. By reducing or eliminating the effectiveness of the contaminants, the age and performance of the bearing isolator 10, the bearing 12, and the conductive segments 46 can be enhanced. The opening of the first axial interface spacing 34a faces rearwardly and toward the device housing 16 and away from the flow of contaminants, whereby the contaminant or cooling fluid is typically directed along the axis of the shaft 14, and The flow direction of the device housing 16 is directed.
為利於在軸體14上或鄰近於其之電量之放電,軸承隔離器10可包含至少一導電段46設於定子20中。定子20可設有一鄰近於軸承12之導電段限位腔室,此導電段限位腔室之導電段46可定位及固定於其中,以使導電段46與軸體14相接處。當電荷累積於軸體14上時,導電段46可將此些電荷經由軸承隔離器10消散至設備殼體16。導電段限位腔室之大小與配置可視軸承隔離器10之應用而定,亦可依每一導電段46之大形式與大小而定。因此,導電段環形渠道之大小與配置並無特別限制。To facilitate discharge of electrical energy on or adjacent to the axle body 14, the bearing isolator 10 can include at least one electrically conductive segment 46 disposed in the stator 20. The stator 20 can be provided with a conductive segment limiting chamber adjacent to the bearing 12. The conductive segment 46 of the conductive segment limiting chamber can be positioned and fixed therein such that the conductive segment 46 meets the shaft 14. When charge builds up on the shaft 14, the conductive segments 46 can dissipate this charge to the device housing 16 via the bearing isolator 10. The size and configuration of the conductive segment limiting chamber may depend on the application of the bearing spacer 10, and may also depend on the size and size of each conductive segment 46. Therefore, the size and configuration of the conductive segment annular channel are not particularly limited.
將導電段限位腔室設置成環形渠道並非較佳的,主因在於此設置將會對性能與製造上產生不便與困難。導電段限位腔室之一較佳設置係為一徑向渠道52,如圖7-14所示之CDR40之實施例,或如圖15A-15C所示之徑向型CDR80之實施例。It is not preferable to arrange the conductive segment limiting chamber as an annular channel, and the main reason for this arrangement is inconvenience and difficulty in performance and manufacturing. One of the conductive segment limiting chambers is preferably a radial channel 52, as in the embodiment of CDR 40 shown in Figures 7-14, or an embodiment of a radial CDR 80 as shown in Figures 15A-15C.
於如圖所示之實施例中,軸承隔離器10係設有接納凹槽24。此接納凹槽24可設於軸承隔離器10之鄰近軸體14之內側面上,如圖3所示。通常而言,接納凹槽24係有利於將CDR40設於軸承隔離器10之內。惟,視軸承隔離器10之特定應用為何,其他結構亦可設於接納凹槽24之內。In the illustrated embodiment, the bearing isolator 10 is provided with a receiving recess 24. The receiving recess 24 can be provided on the inner side of the bearing isolator 10 adjacent to the shaft 14, as shown in FIG. In general, receiving the recess 24 facilitates the placement of the CDR 40 within the bearing isolator 10. However, depending on the particular application of the bearing isolator 10, other configurations may be provided within the receiving recess 24.
如圖2及3所示之軸承隔離器10,其可包括複數個介於定子20與轉子30間之徑向與軸向介面通道,以令定子突出部26、28可與轉子軸向凹槽39相互配合作用,並可令轉子突出部36、38與定子軸向凹槽29相互配合作用。可以理解的是,突出部與凹槽可具有相當多種不同之配置及/或方向等設置,因此所述於定子20及/或轉子30內之突出部與凹槽皆可具有相當多種不同之配置及/或方向,而無特別限制。所述之軸承隔離器10亦設有任何形式之定子20及/或轉子30,其中定子20可配置有用於將至少一導電段46維持於其內之導電段限位腔室,或接納凹槽等,詳如下。The bearing isolator 10 as shown in Figures 2 and 3 can include a plurality of radial and axial interface passages between the stator 20 and the rotor 30 to allow the stator projections 26, 28 to be axially grooved with the rotor. 39 cooperates with each other and allows the rotor projections 36, 38 to cooperate with the stator axial grooves 29. It can be understood that the protrusions and the grooves can have a plurality of different configurations and/or orientations, and thus the protrusions and the grooves in the stator 20 and/or the rotor 30 can have a plurality of different configurations. And / or direction, without special restrictions. The bearing isolator 10 is also provided with any form of stator 20 and/or rotor 30, wherein the stator 20 can be configured with a conductive segment limiting chamber for maintaining at least one conductive segment 46 therein, or a receiving recess Etc., as detailed below.
如圖4所示之電流分流環(CDR)40之第一實施例,及如圖5所示之該實施例之軸向視圖中,CDR40可用於任何有可能累積電荷於其一部份之旋轉設備上,如電動馬達、齒輪箱、軸承及其他設備等。CDR40之第一實施例可經設計,設於設備殼體16及自該設備殼體16突出之軸體14之間,並可相對於其旋轉之。As shown in the first embodiment of the current shunt ring (CDR) 40 shown in FIG. 4, and in the axial view of the embodiment shown in FIG. 5, the CDR 40 can be used for any rotation that is likely to accumulate charge in a portion thereof. Equipment such as electric motors, gearboxes, bearings and other equipment. The first embodiment of the CDR 40 can be designed to be disposed between the device housing 16 and the shaft body 14 projecting from the device housing 16 and is rotatable relative thereto.
大致上而言,CDR40包含有CDR主體41,此主體可固設於設備殼體16上。於第一實施例中,第一壁43及第二壁44係自CDR主體41延伸出,並界定有環形渠道42。至少一導電段46係固定式地限位於該環形渠道42中,故使導電段46與軸體14相互接觸,進而產生介於軸體14與設備殼體16間之低阻抗路徑。In general, the CDR 40 includes a CDR body 41 that can be secured to the device housing 16. In the first embodiment, the first wall 43 and the second wall 44 extend from the CDR body 41 and define an annular channel 42. At least one conductive segment 46 is fixedly disposed in the annular channel 42 such that the conductive segment 46 and the shaft body 14 are in contact with each other, thereby generating a low impedance path between the shaft body 14 and the device housing 16.
圖6係該CDR40之第一實施例之截面圖。如圖6所示,第一壁43之軸向厚度係小於第二壁44之厚度。於第一實施例中,導電段46限位於環形渠道42之方式,乃係藉由先將導電段46定位於環形渠道42中,再使第一壁43產生變形,以縮小位於第一與第二壁43、44末端間之間隙,進而達成之。藉由將第一壁43產生變形之方式,可令導電段46被限位於環形渠道42之中。視用於構成導電段46之材質而定,第一壁43所產生之變形可對導電段46之一部分施壓,以進一步將導電段46相對於軸體14固定定位之。Figure 6 is a cross-sectional view of the first embodiment of the CDR 40. As shown in FIG. 6, the axial thickness of the first wall 43 is less than the thickness of the second wall 44. In the first embodiment, the conductive segment 46 is limited to the annular channel 42 by first positioning the conductive segment 46 in the annular channel 42 and deforming the first wall 43 to reduce the first and the first The gap between the ends of the two walls 43, 44 is further achieved. The conductive segment 46 can be confined within the annular channel 42 by deforming the first wall 43. Depending on the material used to form the conductive segments 46, the deformation produced by the first wall 43 may press a portion of the conductive segments 46 to further securely position the conductive segments 46 relative to the shaft 14.
圖6顯示CDR徑向外表面45之細部視圖。該CDR徑向外表面45可經組態,而於軸向長度上具有一微小角度,進而使CDR40可壓設於設備殼體16中。於第一實施例中,此角度為1度,但於其他圖未示之實施例中,亦可具有其他較大或較小之角度。同時,於第一實施例中,當CDR40係安裝於設備殼體16內時,第一壁43係鄰近於軸承12之位置上。惟,於其他圖未示之實施例中,當CDR40係安裝於設備殼體16內時,第二壁44亦可鄰近於軸承12之位置上,故於此情況下時,CDR徑向外表面45之角度將與圖6所示呈相反之角度。CDR主體41、環形渠道42、第一壁43、第二壁44,及CDR徑向外表面45之最佳尺寸/方向,皆可視CDR40之特定應用而配置之,故CDR40並不侷限於任何此些元件之尺寸與方向等。Figure 6 shows a detailed view of the radially outer surface 45 of the CDR. The CDR radial outer surface 45 can be configured with a slight angle in the axial length to allow the CDR 40 to be press fit into the device housing 16. In the first embodiment, the angle is 1 degree, but in other embodiments not shown, other larger or smaller angles may be used. Meanwhile, in the first embodiment, when the CDR 40 is mounted in the device housing 16, the first wall 43 is adjacent to the position of the bearing 12. However, in other embodiments not shown, when the CDR 40 is mounted in the device housing 16, the second wall 44 may also be adjacent to the bearing 12, so in this case, the CDR radial outer surface The angle of 45 will be at an opposite angle to that shown in FIG. The optimal size/direction of the CDR body 41, the annular channel 42, the first wall 43, the second wall 44, and the CDR radial outer surface 45 can be configured depending on the particular application of the CDR 40, so the CDR 40 is not limited to any The size and direction of these components.
如前述之軸承隔離器10,具有導電段限位腔室之CDR40並不建議將其設置為一環形渠道,主因在於如此之設置將會對性能與製造方面產生較不當之影響。反之,其他於此所述之CDR之實施例,只要其未具有環形渠道42及安裝困難等之結構,皆係可能與較佳的。As with the bearing isolators 10 described above, the CDR 40 with the conductive segment limiting chamber is not recommended to be provided as an annular channel, mainly because such a setting would have a undue influence on performance and manufacturing. Conversely, other embodiments of the CDRs described herein may be preferred as long as they do not have an annular channel 42 and are difficult to install.
如下所述之CDR40之其他實例中,CDR40可藉由設於CDR40或設備殼體16上之安裝孔54、條塊70及鎖附件72,以安裝至設備殼體16上。CDR40亦可藉由其他合適之方法與結構,以安裝至設備殼體16上,而仍屬CDR40之範圍與精神內。In other examples of CDRs 40 as described below, the CDRs 40 can be mounted to the device housing 16 by mounting holes 54, straps 70, and lock attachments 72 provided on the CDR 40 or device housing 16. The CDR 40 can also be mounted to the device housing 16 by other suitable methods and structures while remaining within the scope and spirit of the CDR 40.
於如圖4及5所示之CDR40之實施例中,三個導電段46係設於環形渠道42內。而導電段46之最佳數量,及每一導電段46之尺寸及/或外型等,則皆可視CDR40之應用而定之,故無特別限制。所有導電段46之最佳整體長度,及導電段46與軸體14相接處之總表面積,亦可因應用不同而有所差異,故此些特徵並非用於限制CDR40或設有導電段46之軸承隔離器10(如圖2及3所示之軸承隔離器)之範圍。In the embodiment of CDR 40 as shown in FIGS. 4 and 5, three conductive segments 46 are disposed within annular channel 42. The optimum number of conductive segments 46, and the size and/or shape of each conductive segment 46 can be determined by the application of the CDR 40, and is not particularly limited. The optimum overall length of all conductive segments 46, and the total surface area at which the conductive segments 46 meet the shaft 14 may vary from application to application, and such features are not intended to limit the CDR 40 or provide conductive segments 46. The range of bearing isolators 10 (bearing isolators as shown in Figures 2 and 3).
於如圖4-6所示之實施例中,CDR40之大小可經組態,以銜接於具有接納凹槽24之軸承隔離器10上,如圖2及3所示之軸承隔離器10。如前述,圖2及3顯示一軸承隔離器10之一實施例經設計以與一CDR40相銜接。接納凹槽24可為形成於定子20中之內凹部,其可經組態而具有可容納如圖4-6所示之CDR40之大小與外型。CDR40可壓設於接納凹槽24中,或其亦可藉由任何方法或結構,以固定至定子20上,以可操作式地將CDR40固設於定子20上,此些方法包括但不僅限於如螺絲組、焊接等。當CDR40正確地銜接至設於定子20上之接納凹槽24中時,CDR徑向外表面45係抵接於該接納凹槽24之內表面,並與其接觸。In the embodiment shown in Figures 4-6, the CDR 40 can be sized to engage the bearing isolator 10 having the receiving recess 24, such as the bearing isolator 10 shown in Figures 2 and 3. 2 and 3, one embodiment of a bearing isolator 10 is designed to interface with a CDR 40. The receiving recess 24 can be an inner recess formed in the stator 20 that can be configured to accommodate the size and shape of the CDR 40 as shown in Figures 4-6. The CDR 40 can be press-fitted into the receiving recess 24, or it can be fixed to the stator 20 by any method or structure to operatively secure the CDR 40 to the stator 20. These methods include, but are not limited to, Such as screw sets, welding, etc. When the CDR 40 is properly engaged into the receiving recess 24 provided in the stator 20, the CDR radial outer surface 45 abuts against and contacts the inner surface of the receiving recess 24.
於設有導電段46之CDR40或軸承隔離器10之任一實施例中,該導電段46可由碳材質所製成,故其具有導電與天然潤滑特性。於一實施例中,導電段46係由碳網所製成,而此碳網可為由美國Chesterton公司所製造與設計之447-1材質。於其他實施例中,導電段46於碳網之外表面並無塗覆有任何層體。當網狀或織物材質係用於製造導電段46時,導電段46接觸軸體14之表面,往往會呈磨損或非平滑之表面,也因此可形成適當之特性能於部分應用中減少旋轉摩擦。於軸體14相對於導電段46旋轉一小段時間後,導電段46之部分實施例將會對軸體14之表面產生磨損,故介於導電段46與軸體14之間之摩擦將因此而減少。導電段46可為纖維材質,或固體材質,而無特別限制。In any of the embodiments of the CDR 40 or the bearing isolator 10 provided with the conductive segments 46, the conductive segments 46 may be made of a carbon material so that they have electrical and natural lubricating properties. In one embodiment, the conductive segment 46 is made of a carbon mesh, and the carbon mesh may be a 447-1 material manufactured and designed by Chesterton, USA. In other embodiments, the conductive segments 46 are not coated with any layer on the outer surface of the carbon mesh. When the mesh or fabric material is used to make the conductive segments 46, the conductive segments 46 contact the surface of the shaft 14, which tends to be a worn or non-smooth surface, and thus can form appropriate characteristics to reduce rotational friction in some applications. . After the shaft 14 is rotated relative to the conductive segment 46 for a short period of time, some embodiments of the conductive segment 46 will wear on the surface of the shaft 14, so that the friction between the conductive segment 46 and the shaft 14 will cut back. The conductive segment 46 may be made of a fiber material or a solid material without particular limitation.
大致上而言,較佳係可確保介於軸體14與設備殼體16間之阻抗之大小,落於0.2至1.0歐姆此範圍之間,以確保累積於軸體14上之電荷可經由設備殼體16放電至馬達(圖未示)之底座,而非通過軸承12。介於軸體14與設備殼體16之間,則可藉由介於軸承隔離器10與設備殼體16、軸承隔離器10與CDR40,及/或CDR40與設備殼體16之間的確實配置,而具有相當小之間隙,以降低其阻抗之大小。因此,當軸承隔離器10與設備殼體16、軸承隔離器10與CDR40,及/或CDR40與設備殼體16之間的間隔越小,則介於軸體14與設備殼體16之間的阻抗將會越小。In general, it is preferred to ensure that the magnitude of the impedance between the shaft body 14 and the device housing 16 falls between 0.2 and 1.0 ohms to ensure that the charge accumulated on the shaft body 14 can be passed through the device. The housing 16 is discharged to the base of a motor (not shown) rather than through the bearing 12. Between the shaft body 14 and the device housing 16, the actual configuration between the bearing isolator 10 and the device housing 16, the bearing isolator 10 and the CDR 40, and/or between the CDR 40 and the device housing 16 can be There is a relatively small gap to reduce the impedance. Thus, the smaller the spacing between the bearing isolator 10 and the device housing 16, the bearing isolator 10 and the CDR 40, and/or the CDR 40 and the device housing 16, is between the shaft body 14 and the device housing 16. The impedance will be smaller.
於圖未示之其他實例中,導電絲(圖未示)可接合至CDR40或軸承隔離器10上,或可埋設於導電段46中,以接合至CDR40或軸承隔離器10上。此些絲可由鋁、銅、金、碳、導電聚合物、導電彈性物,及其他具有適用於特定應用上之導電特性之導電材質所製成。任何具有足夠之潤滑度與夠低之阻抗之材質,皆可用於製造設於CDR40及/或軸承隔離器10中之導電段46。In other examples not shown, a conductive filament (not shown) may be bonded to the CDR 40 or bearing isolator 10 or may be embedded in the conductive segment 46 for bonding to the CDR 40 or bearing isolator 10. These filaments may be made of aluminum, copper, gold, carbon, conductive polymers, conductive elastomers, and other electrically conductive materials having conductive properties suitable for the particular application. Any material having sufficient lubricity and low enough impedance can be used to fabricate the conductive segments 46 disposed in the CDR 40 and/or the bearing isolator 10.
於另一圖未示之CDR40實施例中,CDR40係接合至軸體14,並隨之旋轉。CDR40之第一與第二壁43、44係自軸體14延伸出,且CDR主體41係鄰近於軸體14。於軸體14旋轉時,該軸體14旋轉之離心力,可使導電段46及/或導電絲徑向擴張。此擴張可使導電段46及/或絲與設備殼體16相接觸,且縱使油或其他沾汙物及/或潤滑劑(其可造成阻抗之增加,並進而降低CDR40所具有之可消散介於軸體14與設備殼體16間之電荷之能力)已收集於介於CDR40及設備殼體16間之區域時,其亦可形成彼此間之接觸。In another embodiment of the CDR 40, not shown, the CDR 40 is attached to the shaft 14 and rotates therewith. The first and second walls 43, 44 of the CDR 40 extend from the shaft 14, and the CDR body 41 is adjacent to the shaft 14. When the shaft body 14 rotates, the centrifugal force of the rotation of the shaft body 14 can radially expand the conductive segments 46 and/or the conductive wires. This expansion allows the conductive segments 46 and/or wires to contact the device housing 16 and, in the case of oil or other contaminants and/or lubricants (which can cause an increase in impedance and thereby reduce the dissipative properties of the CDR 40) The ability to charge between the shaft 14 and the device housing 16 has been collected between the CDR 40 and the device housing 16 and may also form contact with one another.
於圖未示之另一實施例中,導電套筒(圖未示)可設於軸體14上。此實施例係對軸體14已具有受磨損或非平滑之表面,而造成導電段46上之過度磨損之情況,特別有其功效。導電套筒(圖未示)可由任何適用於特定應用上具有導電特性之材質,且此導電套筒(圖未示)亦可設計為具有一平滑之徑向外表面。導電套筒(圖未示)故可作為傳導介於軸體14與設於CDR40或軸承隔離器10上之導電段46間之電荷。同時,另一實施例則對軸體14已具有磨損或非平滑之外表面,且其中導電絲或線係***至導電段46內之情況時,特別有其功效。此些導電絲或線可為消耗性的,並可填入至軸體14之表面上之凹陷處或孔洞等。In another embodiment, not shown, a conductive sleeve (not shown) may be provided on the shaft 14. This embodiment is particularly effective in the case where the shaft body 14 already has a worn or non-smooth surface which causes excessive wear on the conductive segments 46. The conductive sleeve (not shown) may be of any material suitable for the particular application, and the conductive sleeve (not shown) may also be designed to have a smooth, radially outer surface. A conductive sleeve (not shown) can be used to conduct electrical charge between the shaft 14 and the conductive segments 46 disposed on the CDR 40 or bearing spacer 10. At the same time, another embodiment has particular utility when the shaft 14 already has a worn or non-smooth outer surface, and wherein the conductive filaments or wires are inserted into the conductive segments 46. Such conductive filaments or wires may be consumable and may be filled into depressions or holes or the like on the surface of the shaft body 14.
於圖未示之另一實施例中,導電螺絲(圖未示)可由合適之導電材質所製成,其可***至導電段46內。又,硬式彈簧導電筒亦可以徑向之方向設於CDR40及/或軸承隔離器10內,進而接觸軸體14之徑向外表面。In another embodiment, not shown, a conductive screw (not shown) may be formed from a suitable electrically conductive material that can be inserted into the conductive segment 46. Further, the hard spring conductive tube may be disposed in the radial direction of the CDR 40 and/or the bearing isolator 10 to contact the radially outer surface of the shaft body 14.
如圖4-6所示之CDR40,雖其為具有相當特徵之設計,惟其並非CDR40之較佳時施例,如前述。基於種種考量,包括性能與製造困難度等,CDR40之其他實施例係較佳的。尤指,如圖7-14所示之兩件型CDR40,其詳細內容將於下解說之,及圖15A及15B所示之徑向型CDR80之實施例,亦皆優於圖4-6所示之實施例。兩件型 CDR 之實施例 The CDR 40 shown in Figures 4-6, although of a design with comparable features, is not a preferred embodiment of the CDR 40, as previously described. Other embodiments of CDR 40 are preferred based on various considerations, including performance and manufacturing difficulties. In particular, the two-piece CDR 40 shown in Figures 7-14, the details of which will be explained below, and the embodiments of the radial CDR 80 shown in Figures 15A and 15B are also superior to those of Figures 4-6. The embodiment shown. Two-piece CDR embodiment
圖7-14顯示CDR40之第二實施例。於CDR40之第二實施例中,該CDR係由內側主體50與外側主體60彼此相銜接所形成之,惟圖7係顯示兩者彼此分離但具有相關聯之關係。於CDR40之第二實施例中,內側主體50與外側主體60可藉由扣接、緊配等方式,彼此相銜接。Figures 7-14 show a second embodiment of CDR 40. In a second embodiment of the CDR 40, the CDRs are formed by the inner body 50 and the outer body 60 engaging each other, but Figure 7 shows that the two are separated from each other but have an associated relationship. In the second embodiment of the CDR 40, the inner body 50 and the outer body 60 can be engaged with each other by fastening, fitting, or the like.
如圖9所示之內側主體50之一立體圖中,其大致呈環狀。內側主體50可包含至少一徑向渠道52設於該內側主體50之外表面,其可包含一主孔58,以供軸體14貫穿定位其中。於如圖9所示之實施例中,其包括有三個徑向渠道52,惟於其他實施例中,亦可具有較多或較少數量之徑向渠道52,因此CDR40之範圍並不侷限於徑向渠道之特定數量。每一徑向渠道52可形成有一擷取部52a於其中,以更適當地固定特定形式之導電段46。可以理解的是,擷取部52a較佳係可用於由可變形或半變形之材質(如圖14B所示)所製成之導電段46上,惟擷取部52a亦可用於具有不同機構特性之材質所製成之導電段46上。如圖所示之徑向渠道52係朝設於主孔58內之軸體14之方向開設之。內側主體50於徑向內外表面上可設有脊部56。此脊部56可配置為與形成於外側主體60上之環形凹槽64相銜接。In a perspective view of one of the inner bodies 50 shown in Fig. 9, it is substantially annular. The inner body 50 can include at least one radial channel 52 disposed on an outer surface of the inner body 50, which can include a main aperture 58 for the shaft 14 to be positioned therethrough. In the embodiment shown in FIG. 9, it includes three radial channels 52. However, in other embodiments, a larger or smaller number of radial channels 52 may be provided, so the range of the CDR 40 is not limited. The specific number of radial channels. Each radial channel 52 can be formed with a dip portion 52a therein to more suitably secure a particular form of conductive segment 46. It can be understood that the capturing portion 52a is preferably used on the conductive segment 46 made of a deformable or semi-deformable material (as shown in FIG. 14B), but the capturing portion 52a can also be used to have different mechanical characteristics. The material is made of conductive segments 46. The radial channel 52 is shown as being oriented in the direction of the shaft 14 provided in the main bore 58. The inner body 50 may be provided with a ridge 56 on the radially inner and outer surfaces. This ridge 56 can be configured to engage an annular groove 64 formed in the outer body 60.
內側主體50之內部可設有一或多個安裝孔54。如圖8-11所示之實施例中,其設有三個安裝孔54。安裝孔54可用於將CDR40故設於設備殼體16或其他如圖11所示之結構上。條塊70或夾可藉由利用鎖附件72,如螺絲或鉚釘等故設於CDR40,以使其可與安裝孔54相銜接,如圖1及8B所示。安裝孔54之有無,主須視CDR40之安裝方式而定。舉例而言,於如圖14A及14B所示之實施例中,內側主體50並不包含任何安裝孔54。可以理解的是,此些實施例最佳係用於軸承隔離器10及/或CDR40之內,其可壓設至設備殼體16或其他結構中。One or more mounting holes 54 may be provided in the interior of the inner body 50. In the embodiment shown in Figures 8-11, it is provided with three mounting holes 54. Mounting holes 54 can be used to place CDR 40 on device housing 16 or other structure as shown in FIG. The strip 70 or clip can be placed on the CDR 40 by means of a lock attachment 72, such as a screw or rivet, such that it can engage the mounting aperture 54, as shown in Figures 1 and 8B. The presence or absence of the mounting holes 54 depends on how the CDR 40 is mounted. For example, in the embodiment shown in Figures 14A and 14B, the inner body 50 does not include any mounting holes 54. It will be appreciated that such embodiments are preferably utilized within bearing isolator 10 and/or CDR 40 that may be crimped into device housing 16 or other structure.
如圖12所示之外側主體60之立體圖所示,其亦可具有大致呈環狀之形體。此外側主體60可設於具有環形凹槽64形成於徑向內表面之底座62上。此環形凹槽64係由第一環形肩部65a及第二環形肩部65b所界定之。徑向突出部66可自底座62徑向向內延伸,以鄰近於該第一或第二肩部65a、65b。如圖所示之實施例中,徑向突出部66係鄰設於第一環形肩部65a,並包括有主孔68形成於其內,以供軸體14穿設其中。As shown in the perspective view of the outer side body 60 shown in Fig. 12, it may have a substantially annular shape. Further, the side body 60 may be provided on a base 62 having an annular groove 64 formed on a radially inner surface. This annular groove 64 is defined by a first annular shoulder 65a and a second annular shoulder 65b. The radial projections 66 can extend radially inward from the base 62 to abut the first or second shoulders 65a, 65b. In the illustrated embodiment, the radial projection 66 is disposed adjacent the first annular shoulder 65a and includes a main bore 68 formed therein for the shaft 14 to pass therethrough.
環形凹槽64可經組態,以使形成於內側主體50中之脊部56可與環形凹槽64相銜接,進而可實質上將內側主體50之軸向位置相對於外側主體60固定之。如圖10及14B所示,脊部56可為傾斜或漸細的,故當內側主體50強迫式推入至外側主體60內時,此脊部56可滑過第二環形肩部65b,並進入至環形凹槽中64,以固定內側主體50與外側主體60。介於脊部56與環形凹槽64間之銜接,隨後亦可防止內側與外側主體50、60之間之分離或脫離等。於其他圖未示之實施例中,脊部56並不侷限於漸細之結構。脊部56及底座62亦可經組態,以形成緊配設至,以防止內側與外側主體50、60之間之分離或脫離等。The annular groove 64 can be configured such that the ridge 56 formed in the inner body 50 can engage the annular groove 64, thereby substantially securing the axial position of the inner body 50 relative to the outer body 60. As shown in Figures 10 and 14B, the ridge 56 can be inclined or tapered so that when the inner body 50 is forced into the outer body 60, the ridge 56 can slide over the second annular shoulder 65b and It enters into the annular groove 64 to secure the inner body 50 and the outer body 60. The engagement between the ridge 56 and the annular groove 64 can then prevent separation or detachment between the inner and outer bodies 50, 60, and the like. In other embodiments not shown, the ridges 56 are not limited to tapered structures. The ridge 56 and the base 62 can also be configured to form a tight fit to prevent separation or disengagement between the inner and outer bodies 50, 60, and the like.
如圖14A及14B所示,內側主體50與外側主體60可經組態,以使徑向突出部66之內表面具有等同於內側主體50之內表面之直徑,故當軸體14安裝時,內側與外側主體50、60可具有相同之間隔。可以理解的是,於CDR40之大部份應用上,其安裝可將如圖14A所示之表面係於設備殼體16或其他結構之軸向外側上。惟,若CDR40係銜接至軸承隔離器10時,CDR40之方向可經調整,以使如圖14A所示之表面朝向設備殼體16或其他結構之設有軸承隔離器10之內部。As shown in FIGS. 14A and 14B, the inner body 50 and the outer body 60 can be configured such that the inner surface of the radial projection 66 has a diameter equivalent to the inner surface of the inner body 50, so that when the shaft 14 is mounted, The inner and outer bodies 50, 60 can have the same spacing. It will be appreciated that for most applications of the CDR 40, the mounting may be such that the surface as shown in Figure 14A is attached to the axially outer side of the device housing 16 or other structure. However, if the CDR 40 is coupled to the bearing isolator 10, the orientation of the CDR 40 can be adjusted such that the surface as shown in FIG. 14A faces the interior of the device housing 16 or other structure in which the bearing isolator 10 is disposed.
如圖11所示,導電段46可設於每一徑向渠道52中。可以理解的是,徑向渠道52可形成於內側主體50之軸向表面,故於組裝CDR40時,其係鄰設於外側主體60之徑向突出部66,如圖14A及14B所示。此方向設置可固定導電段46之軸向位置。如前述,設有徑向渠道52之CDR40以用於導電段46之限位,係相較於具有環形渠道52之CDR40較為佳。通常,但仍需視構成之材質,導電段46可經組態而使其大小可延伸超過內側主體50之較短直徑,而進入至主孔58中,以與軸體14相接觸。徑向渠道52之大小亦可經組態以使其不與內側主體50之外環面相交。如此之結構可防止導電段46與外側主體60之環形凹槽64相接觸。As shown in FIG. 11, a conductive segment 46 can be disposed in each of the radial channels 52. It can be understood that the radial channel 52 can be formed on the axial surface of the inner body 50, so that when the CDR 40 is assembled, it is disposed adjacent to the radial protrusion 66 of the outer body 60, as shown in FIGS. 14A and 14B. This orientation is set to fix the axial position of the conductive segments 46. As previously mentioned, the CDRs 40 of the radial channels 52 are provided for the limits of the conductive segments 46, as compared to the CDRs 40 having the annular channels 52. Typically, but still depending on the material of the composition, the conductive segments 46 can be configured to extend beyond the shorter diameter of the inner body 50 into the main bore 58 for contact with the shaft 14. The radial channel 52 can also be sized such that it does not intersect the outer annulus of the inner body 50. Such a configuration prevents the conductive segments 46 from coming into contact with the annular grooves 64 of the outer body 60.
軸承隔離器10與CDR40可由任何可加工之材質所製成,如不鏽鋼、青銅、鋁、金、銅,及其組合等,或其他具有低阻抗之材質。CDR40或軸承隔離器10可藉由凸緣安裝、緊配等方式結合至設備殼體16上,或藉由其他結構或方法等,如透過複數條塊70與鎖附件72等以達成之。The bearing isolator 10 and CDR 40 can be made of any machinable material such as stainless steel, bronze, aluminum, gold, copper, combinations thereof, or the like, or other materials having low impedance. The CDR 40 or the bearing isolator 10 can be coupled to the device housing 16 by flange mounting, tight fitting, etc., or by other structures or methods, such as through a plurality of strips 70 and lock attachments 72, and the like.
於某些應用上,軸承隔離器10之性能可藉由避免使用O形環18及其配合之設有定子20與轉子30之凹槽而提升之,如圖2及3所示。由高阻抗材質所製成之O形環18(如橡膠及/或矽)將可抑制介於軸承隔離器10及設備殼體16間之導電性,進而會降低軸承隔離器10在整體消散電荷之性能。但若O形環18係由低阻抗之材質所製成,其則可用於CDR40及/或軸承隔離器10之任何應用上。CDR40、內側主體50、外側主體60之最佳尺寸,及其他特徵等,可視CDR40之特定應用而定,故其尺寸與特徵等不應作為限制CDR40之範圍。單件型 CDR 之第二實施例 In some applications, the performance of the bearing isolator 10 can be enhanced by avoiding the use of the O-ring 18 and its mating grooves provided with the stator 20 and the rotor 30, as shown in Figures 2 and 3. An O-ring 18 (such as rubber and/or crucible) made of a high-impedance material will inhibit electrical conductivity between the bearing isolator 10 and the device housing 16, thereby reducing the overall dissipation of the bearing isolator 10 Performance. However, if the O-ring 18 is made of a low impedance material, it can be used in any application of the CDR 40 and/or the bearing isolator 10. The optimal size of the CDR 40, the inner body 50, the outer body 60, and other features, depending on the particular application of the CDR 40, should not be limiting as to the scope of the CDR 40. Second embodiment of single-piece CDR
徑向型CDR80係CDR40之另一實施例,如圖15A及15B所示,其具有一環狀結構,並設有一主孔88於其中心。於CDR40之其他實例中,CDR40亦可藉由任何結構及/或方法安裝至旋轉設備上,而無特別限制。如圖15A及15B所示之徑向型CDR80之實施例中,其包括三個條塊70藉由鎖附件72結合至徑向型CDR80上。其他鎖附件72亦可用於將條塊70固定至旋轉設備上,進而將徑向型CDR80固定至旋轉設備上。於CDR80之其他實施例中,徑向型CDR80之徑向外表面85a係以緊配方式壓設入旋轉設備殼體16中。惟,本發明之範圍不應僅限於此安裝徑向型CDR80之方法。Another embodiment of the radial type CDR 80 series CDR 40, as shown in Figs. 15A and 15B, has an annular structure and is provided with a main hole 88 at its center. In other examples of CDR 40, CDR 40 can also be mounted to a rotating device by any structure and/or method without particular limitation. In the embodiment of the radial type CDR 80 shown in Figures 15A and 15B, it includes three strips 70 bonded to the radial type CDR 80 by a lock attachment 72. Other lock attachments 72 can also be used to secure the bar 70 to the rotating device to secure the radial CDR 80 to the rotating device. In other embodiments of the CDR 80, the radially outer surface 85a of the radial CDR 80 is press fit into the rotating device housing 16 in a tight fit. However, the scope of the invention should not be limited to the method of installing the radial type CDR 80.
如圖所示之徑向型CDR80之實施例中,其具有徑向渠道82,由徑向外表面85a延伸至徑向內表面85b。每一徑向渠道82可包含一徑向渠道架83,如圖15B所示。於如圖所示之實施例中,徑向渠道架83可鄰設於該徑向型CDR80之徑向內表面85b。In the embodiment of the radial type CDR 80 as shown, it has a radial channel 82 extending from a radially outer surface 85a to a radially inner surface 85b. Each radial channel 82 can include a radial channel frame 83, as shown in Figure 15B. In the illustrated embodiment, the radial channel frame 83 can be disposed adjacent the radially inner surface 85b of the radial CDR 80.
導電組件86可經組態,以固定密合配置於徑向渠道82內。如圖15C所示之導電組件86之一實施例中,導電組件86可包含一接合件86a,其主要設於徑向渠道82及接觸部86b中,並自徑向渠道82徑向向內延伸出。接合件86a可將具有導電組件86之部件限位於其上之結構,所述部件包括但不僅限於化學黏著劑、結構帽或栓,及其組合等。其他形式之導電組件86亦可用於徑向型CDR80上,而無特別限制。The electrically conductive component 86 can be configured to be disposed in a fixed tight fit within the radial channel 82. In one embodiment of the conductive component 86 as shown in FIG. 15C, the conductive component 86 can include an engagement member 86a disposed primarily in the radial channel 82 and the contact portion 86b and extending radially inward from the radial channel 82. Out. The engagement member 86a can structure a component having the electrically conductive component 86 thereon, including but not limited to chemical adhesives, structural caps or pegs, combinations thereof, and the like. Other forms of conductive component 86 can also be used on the radial type CDR 80 without particular limitation.
於徑向型CDR80中之導電組件86係可為可更換的。意即,當導電組件86之接觸部86b已消耗或磨損後,或導電組件86因其他原因而需更換時,使用者可將導電組件86自徑向渠道82拆下,並將一新的導電組件86插置於其中。多環 CDR 之實施例 The conductive component 86 in the radial type CDR 80 can be replaceable. That is, when the contact portion 86b of the conductive member 86 has been consumed or worn, or the conductive member 86 needs to be replaced for other reasons, the user can remove the conductive member 86 from the radial channel 82 and bring a new conductive Component 86 is inserted therein. Embodiment of multi-ring CDR
圖16A-16D係顯示多環CDR100之第一實施例。多環CDR100之實施例係類似於如圖7-14B所揭露之兩件型CDR40之內容。多環CDR100包含有一限制件110,具有至少二個環體120固定於其上。限制件110可大致上呈環狀,並具有限制件主孔118設於其中心,此限制件主孔118可對應於每一環體主孔128。16A-16D show a first embodiment of a multi-loop CDR 100. The embodiment of the multi-ring CDR 100 is similar to the content of the two-piece CDR 40 as disclosed in Figures 7-14B. The multi-ring CDR 100 includes a restraining member 110 having at least two ring bodies 120 secured thereto. The restricting member 110 can be substantially annular and has a restricting member main hole 118 provided at a center thereof, and the restricting member main hole 118 can correspond to each of the ring main holes 128.
限制件110可形成有複數個環形凹槽112a、112b、112c、112d於限制件底座111之徑向內表面上,以作為多個環體120之載面。如圖所示之多環CDR100之實施例中,其總共包括有四個環體120及四個環形凹槽112。惟,於其他實施例中,其亦可具有較多或較少數量之環體120及對應之環形凹槽112,故多環CDR100之範圍並不受其限制。The restricting member 110 may be formed with a plurality of annular grooves 112a, 112b, 112c, 112d on the radially inner surface of the restricting member base 111 as a carrier surface of the plurality of rings 120. In the embodiment of the multi-ring CDR 100 as shown, it comprises a total of four ring bodies 120 and four annular grooves 112. However, in other embodiments, it may have a larger or smaller number of rings 120 and corresponding annular grooves 112, so the range of the multi-ring CDR 100 is not limited thereto.
環體120可設有複數個徑向渠道122,如設於圖7-14所示之CDR40之實施例之內側主體50之結構。徑向渠道122通常係設於環體120之內軸向表面127a上。導電段116則可設於每一徑向渠道122上。同時,每一徑向渠道122可設有一擷取部122a,以更佳利於限位該導電段116。The ring body 120 can be provided with a plurality of radial channels 122, such as the structure of the inner body 50 of the embodiment of the CDR 40 shown in Figures 7-14. The radial channels 122 are typically disposed on the axial surface 127a of the ring body 120. Conductive segments 116 may be disposed on each of the radial channels 122. At the same time, each radial channel 122 can be provided with a dip portion 122a to better limit the conductive segment 116.
限制件壁114可自第一環形凹槽112a徑向向內朝限制件主孔118延伸之,此限制件壁114係如同如圖7-14所示之CDR40實施例中之外側主體60上之徑向突出部66。於如圖所示之實施例中,限制件壁114可實質上垂直於限制件底座111。限制件壁114可作為阻擋最內環體120之功用,如圖16C及16D所示。最內環體120之內軸向表面127a可抵接於限制件壁114上,進而將導電段116壓入並定位於介於環體120及限制件壁114間之最內環體120之徑向渠道122中。此最內環體120之環體徑向外表面125可銜接至第一環形凹槽112a,以藉由干涉緊配方式將最內環體120固定至限制件110上。The restrictor wall 114 can extend radially inwardly from the first annular groove 112a toward the restrictor main bore 118, which is as in the outer side body 60 of the CDR 40 embodiment as shown in Figures 7-14. Radial protrusion 66. In the illustrated embodiment, the restrictor wall 114 can be substantially perpendicular to the restraint base 111. The restrictor wall 114 can function as a barrier to the innermost ring body 120, as shown in Figures 16C and 16D. The inner axial surface 127a of the innermost ring body 120 can abut against the restrictor wall 114, thereby pressing the conductive segment 116 into and positioning the innermost ring body 120 between the ring body 120 and the restrictor wall 114. To channel 122. The annular radially outer surface 125 of the innermost ring body 120 can be coupled to the first annular groove 112a to secure the innermost ring body 120 to the restraint 110 by an interference fit.
環體120之直接位於最內環體120外側之內軸向表面127a,可抵接於最內環體120之外軸向表面127b,進而將導電段116壓入並定位於環體120之徑向渠道122中,而設於環體120與最內環體120之間。環體120之直接位於最內環之外側之環體徑向外表面125,可與第二環形凹槽112b相銜接,其可藉由干涉緊配方式將環體120固定至限制件上,如圖16C及16D所示。此設置方式亦可用於所有環體120與限制件110之銜接上。The inner axial surface 127a of the ring body 120 directly outside the innermost ring body 120 can abut against the axial surface 127b outside the innermost ring body 120, thereby pressing the conductive segment 116 into and positioning the ring body 120. In the channel 122, it is disposed between the ring body 120 and the innermost ring body 120. The ring body radially outer surface 125 of the ring body 120 directly on the outer side of the innermost ring can be engaged with the second annular groove 112b, and the ring body 120 can be fixed to the limiting member by interference fit, such as Figures 16C and 16D are shown. This arrangement can also be used to interface all of the ring bodies 120 with the restraining members 110.
最外環體120可設有一位於環體徑向外表面125上之脊部126。此脊部126可具有自內軸向表面127a呈一向上彎曲至外軸向表面127b之角度,而使脊部126可與一形成於最外環形凹槽112(指於如此實施例中所示之第四環形凹槽112d)之卡扣凹槽113相銜接。因此,最外環體120可固定於限制件110上,並可將所有其他環體120藉由脊部126與卡扣凹槽113銜接,進而固定之。此亦如藉由脊部56與環形凹槽64將內側主體50與外側主體60相銜接之方式,如圖7-14所示之CDR40所包含之內側主體50與外側主體60。The outermost ring body 120 can be provided with a ridge 126 on the radially outer surface 125 of the ring body. The ridge 126 can have an angle that curves upwardly from the inner axial surface 127a to the outer axial surface 127b, such that the ridge 126 can be formed with the outermost annular groove 112 (referred to as shown in such an embodiment). The snap groove 113 of the fourth annular groove 112d) is engaged. Therefore, the outermost ring body 120 can be fixed to the restricting member 110, and all the other ring bodies 120 can be fixed by the ridge portion 126 and the snap groove 113. For example, the inner body 50 and the outer body 60 are engaged by the ridge 56 and the annular groove 64, and the inner body 50 and the outer body 60 included in the CDR 40 are as shown in FIG.
於多環CDR100之另一實施例中,此些環體120可藉由鎖附件,如圖17A-17D所示之鎖附件,以固定至限制件110上。於此實施例中,此些環體120可包含有兩個環形段130,且限制件110可設有兩個分離式部件。最內分隔環形段130與限制件110間之互動方式,係類似於前述之多環CDR100之第一實施例之方式。同時,於分離式多環CDR100之鄰近分隔環形段130與對應之導電段116之限位部之間之互動方式,亦類似於前述多環CDR100之第一實施例之方式。為將分隔環形段130限位於其中,環體徑向外表面125與各個附有卡扣凹槽113之環形凹槽112a、112b、112c、112d間之干涉緊配,係與位於最外環形凹槽112與設於最外環體120上之脊部126相互配合作用,以達成之。此干涉緊配固定機構可單獨實施,或可與複數個鎖附件72一同配合實施之,或複數個鎖附件72可單獨實施之,以作為固定機構。若有使用鎖附件72,則環形段130可形成有孔132以容納鎖附件72。In another embodiment of the multi-ring CDR 100, the ring bodies 120 can be secured to the restraining member 110 by a lock attachment, such as the lock attachment shown in FIGS. 17A-17D. In this embodiment, the ring bodies 120 may include two annular segments 130, and the restricting member 110 may be provided with two separate components. The manner in which the innermost spaced annular segment 130 interacts with the restricting member 110 is similar to that of the first embodiment of the multi-ring CDR 100 described above. At the same time, the interaction between the adjacent segment ring segment 130 of the split multi-ring CDR 100 and the corresponding portion of the corresponding conductive segment 116 is similar to that of the first embodiment of the multi-ring CDR 100. In order to limit the partitioning ring segment 130 therein, the radial outer surface 125 of the ring body is closely matched with the interference between the annular grooves 112a, 112b, 112c, 112d each having the snap groove 113, and is located at the outermost annular concave The groove 112 cooperates with the ridge 126 provided on the outermost ring body 120 to achieve this. The interference fit securing mechanism can be implemented separately, or can be implemented with a plurality of lock attachments 72, or a plurality of lock attachments 72 can be implemented separately as a securing mechanism. If a lock attachment 72 is used, the annular segment 130 can be formed with a bore 132 to receive the lock attachment 72.
如圖17A─17D所示,墊環140可用於CDR40、80、100之特定實施中。墊環140可由二個不同元件所組成,此些元件可經由複數個對應之對位銷接納部142、鎖附件孔143、鎖附件接納部144及對應之對位銷141及鎖附件72,以彼此固定之。如圖17B所示之實施例中,此二個定位銷141及對應之對位銷接納部142可定位於墊環140之接縫上,以正確地將其二元件對位之。二個鎖附件72係分別設於對應之鎖附件孔143中,以使每一鎖附件72之一部分與對應之鎖附件接納部144相銜接,進而將墊環140之該二元件彼此固定之。As shown in Figures 17A-17D, the backing ring 140 can be used in a particular implementation of the CDRs 40, 80, 100. The backing ring 140 can be composed of two different components that can pass through a plurality of corresponding alignment pin receiving portions 142, lock attachment holes 143, lock attachment receiving portions 144, and corresponding alignment pins 141 and lock attachments 72, Fixed to each other. In the embodiment shown in Fig. 17B, the two positioning pins 141 and the corresponding alignment pin receiving portion 142 can be positioned on the seam of the backing ring 140 to properly align the two components. Two lock attachments 72 are respectively disposed in the corresponding lock attachment holes 143 such that one of each lock attachment 72 is engaged with the corresponding lock attachment receiving portion 144, thereby fixing the two elements of the backing ring 140 to each other.
墊環140之配設可縮小兩部件間之間隔至極小或無法察覺,以防止沾汙物之侵入及潤滑劑自軸承部位滲出。為達此功效,一圈體可先沿其直徑裁切之。所形成之兩個部件,結合後將因材質於裁剪時之移除,而形成一橢圓。因此,此二部件可經加工,以使其再形成一完美圓型或幾近完美圓型。對位銷接納部142與對應之對位銷141及/或鎖附件孔143與對應之鎖附件72,可單獨使用或可同時使用,以於加工時將此二部件相對彼此地定位(如前述)。此二部件之相對穩定度對利用此二部件形成一完美或幾近完美圓型而言係重要的。基於以上,墊環主孔168及O形環渠道145可依規格而設於墊環140中。孔146亦可依使用者之需求而設於墊環140中,故具有完美或幾近完美圓型之墊環140可切確地中心對其方式,套設置軸體或其他結構上。適配型 CDR 之實施例 The backing ring 140 is configured to reduce the spacing between the two components to a minimum or imperceptible to prevent intrusion of contaminants and leakage of lubricant from the bearing locations. In order to achieve this effect, a circle can be cut along its diameter first. The two parts formed, when combined, will be removed due to the material being cut, resulting in an ellipse. Therefore, the two components can be machined to form a perfect round or nearly perfect circle. The alignment pin receiving portion 142 and the corresponding alignment pin 141 and/or the lock attachment hole 143 and the corresponding lock attachment 72 may be used alone or simultaneously to position the two components relative to each other during processing (as described above). ). The relative stability of the two components is important to form a perfect or nearly perfect round shape using the two components. Based on the above, the back ring main hole 168 and the O-ring channel 145 can be disposed in the backing ring 140 according to specifications. The apertures 146 can also be provided in the backing ring 140 as desired by the user, so that the backing ring 140 having a perfect or nearly perfect round shape can be accurately centered, the sleeve is provided with a shaft or other structure. Example of an adaptive CDR
圖18A及18B係顯示一適配型CDR160之一實施例。此適配型CDR160係經設計,以可安裝於多種且具有不同外型之旋轉設備上。此適配型CDR可包含複數個徑向渠道162,自徑向外表面165a延伸至鄰近於主孔168之徑向內表面165b。猶如於徑向型CDR80中之徑向渠道82,設於適配型CDR160之徑向渠道162可包含有徑向渠道架163。因此,導電組件86可固定於每一徑向渠道162中。18A and 18B show an embodiment of an adaptive CDR 160. This compliant CDR 160 is designed to be mounted on a variety of rotating equipment with different shapes. The mating CDR can include a plurality of radial channels 162 extending from the radially outer surface 165a to a radially inner surface 165b adjacent the main bore 168. Like the radial channels 82 in the radial CDR 80, the radial channels 162 disposed in the adaptive CDR 160 can include a radial channel frame 163. Thus, the electrically conductive component 86 can be secured in each of the radial channels 162.
可以理解的是,使用者可於旋轉設備之外側上鑽削孔洞,以令鎖附件72可穿過形成於適配型CDR160中之每一槽161。適配型CDR160可包含複數個內凹部164,以利於容納具有不同外型之多種旋轉設備。適配型CDR160可具有一切口166,延伸入主孔168中,以利於將適配型CDR160安裝至軸體或其他物體上。弧形 CDR 之實施例 It will be appreciated that the user may drill the hole on the outside of the rotating device such that the lock attachment 72 can pass through each of the slots 161 formed in the mating CDR 160. The adaptive CDR 160 can include a plurality of recesses 164 to facilitate accommodation of a plurality of rotating devices having different shapes. The compliant CDR 160 can have a port 166 that extends into the main aperture 168 to facilitate mounting the compliant CDR 160 to a shaft or other object. Example of curved CDR
弧形CDR80a係CDR40之另一實施例。於弧形CDR80a之第一實施例中,如圖19A-19C所示,其為一半圓形結構,並具有設於中心之主孔88及弧形切口81。圖19A係顯示弧形CDR80a之第一實施例之立體圖,其係安裝於軸體14上。圖19B係顯示弧形CDR80a之第一實施例之另一立體圖,但軸體14並未示於圖中,以利視圖呈現。圖19C係顯示如圖19A及19B所示之弧形CDR80a之徑向截面圖。圖20A係顯示弧形CDR80a安裝繞於軸體14之第二實施例之立體圖。圖20B係顯示弧形CDR80a之此實施例之另一立體圖,但軸體14並未示於圖20B中,而圖20C則係其之徑向截面圖。The curved CDR 80a is another embodiment of the CDR 40. In the first embodiment of the curved CDR 80a, as shown in Figs. 19A-19C, it has a semi-circular configuration and has a centrally disposed main hole 88 and an arcuate slit 81. Figure 19A is a perspective view showing a first embodiment of an arcuate CDR 80a mounted on a shaft 14. Figure 19B is another perspective view showing the first embodiment of the curved CDR 80a, but the shaft 14 is not shown in the drawings and is shown in a view. Figure 19C is a radial cross-sectional view showing the curved CDR 80a as shown in Figures 19A and 19B. Figure 20A is a perspective view showing a second embodiment in which the curved CDR 80a is mounted around the shaft 14. Fig. 20B is another perspective view showing this embodiment of the curved CDR 80a, but the shaft 14 is not shown in Fig. 20B, and Fig. 20C is a radial sectional view thereof.
如圖所示之弧形CDR80a之實施例中,其實質上係相同於如圖15A及15B所示之徑向型CDR80。惟,因弧形CDR80a並非一完整環體(但徑向型CDR80則是),弧形CDR80a係較徑向型CDR80在特定應用上,更能夠簡易安裝於某軸體14上,猶如適配型CDR160(如圖18A及18B所示)可較徑向型CDR80更容易安裝。於弧形CDR80之某些實施例中,其較佳係可利用套筒(圖未示)、板件(圖未示)或其他結構,以將弧形CDR80a相對於軸體14定位之。可以理解的是,如圖19A─19C所示之弧形CDR80a之實施例中,其可利用自軸體14延伸之結構,以與一或多個安裝孔54及鎖附件72配合以銜接之。可以理解的是,如圖20A─20C所示之弧形CDR80a之實施例中,其可利用自軸體14延伸之結構,以與一或多個條塊70及一或多個鎖附件72配合以銜接之。惟,任何適用於將弧形CDR80a固定至一結構上之結構及/或方法皆係可能的,而無特別限制。In the embodiment of the curved CDR 80a as shown, it is substantially identical to the radial type CDR 80 as shown in Figures 15A and 15B. However, since the curved CDR 80a is not a complete ring (but the radial type CDR 80 is), the curved CDR 80a is more easily mounted on a certain axial body 14 than the radial type CDR 80 in a specific application, just like an adapted type. The CDR 160 (shown in Figures 18A and 18B) can be more easily installed than the radial type CDR 80. In some embodiments of the curved CDR 80, it is preferred to utilize a sleeve (not shown), a plate (not shown) or other structure to position the curved CDR 80a relative to the shaft 14. It will be appreciated that in the embodiment of the curved CDR 80a as shown in Figures 19A-19C, it may utilize a structure extending from the shaft 14 to engage one or more mounting apertures 54 and lock attachments 72 for engagement. It will be appreciated that in the embodiment of the curved CDR 80a as shown in Figures 20A-20C, it may utilize a structure extending from the shaft 14 to mate with one or more bars 70 and one or more lock attachments 72. To connect. However, any structure and/or method suitable for securing the curved CDR 80a to a structure is possible without particular limitation.
如圖所示之弧形CDR80a之實施例中,其可經組態以使弧形CDR80a延伸超過圓形之180度。具體而言,如圖所示之弧形CDR80a係為一約具有圓形之200度之形體。惟,於弧形CDR80a之其他實施例中,其長度可大於圓形之200度;而於弧形CDR80a之其他實施例中,其長度亦可小於圓形之180度In the embodiment of the curved CDR 80a as shown, it can be configured to extend the curved CDR 80a beyond the 180 degree of the circle. Specifically, the curved CDR 80a as shown is a shape having a shape of about 200 degrees in a circle. However, in other embodiments of the curved CDR 80a, the length may be greater than 200 degrees of the circle; and in other embodiments of the curved CDR 80a, the length may be less than 180 degrees of the circle.
如圖19A─19C所示之弧形CDR80a之實施例中,其包括三個徑向渠道82,自徑向外表面85a延伸至徑向內表面85b。每一徑向渠道82可包含一徑向渠道架83,如圖19C所示。於如圖所示之實施例中,徑向渠道架83可鄰設於弧形CDR80a之徑向內表面85b。如圖20A─20C所示之弧形CDR80a之實施例中,其包括有四個徑向渠道82設於其中。導電組件86可用於固定式地將徑向渠道82及插頭87定位於此導電組件86上,進而固定導電組件86之位置,於如圖15C所示之導電組件86之一實施例。其他導電組件86之不同實施例亦用於弧形CDR80a中,而無特別限制。插頭87之一實施例可為具有螺紋的,並可與形成於徑向渠道82中之螺紋相互配合,如圖19C所示。In the embodiment of the curved CDR 80a shown in Figures 19A-19C, it includes three radial channels 82 extending from the radially outer surface 85a to the radially inner surface 85b. Each radial channel 82 can include a radial channel frame 83, as shown in Figure 19C. In the illustrated embodiment, the radial channel frame 83 can be disposed adjacent the radially inner surface 85b of the curved CDR 80a. In the embodiment of the curved CDR 80a shown in Figures 20A-20C, it includes four radial channels 82 disposed therein. The conductive component 86 can be used to securely position the radial channel 82 and the plug 87 on the conductive component 86, thereby securing the location of the conductive component 86, as in one embodiment of the conductive component 86 as shown in FIG. 15C. Different embodiments of the other conductive components 86 are also used in the curved CDR 80a without particular limitation. One embodiment of the plug 87 can be threaded and can mate with threads formed in the radial channel 82, as shown in Figure 19C.
於弧形CDR80a中之導電組件86係可為可更換的。意即,當導電組件86之接觸部86b已消耗或磨損後,或導電組件86因其他原因而需更換時,使用者可將導電組件86(及/或插頭87若有此部件)自徑向渠道82拆下,並將一新的導電組件86插置於其中。本發明之範圍並不受限於設於弧形CDR80a之徑向渠道82之數量;同樣地,本發明之弧形CDR80a之範圍亦不受限於導電組件之數量。另一 CDR 之實施例 The conductive component 86 in the curved CDR 80a can be replaceable. That is, when the contact portion 86b of the conductive member 86 has been consumed or worn, or the conductive member 86 needs to be replaced for other reasons, the user can self-align the conductive member 86 (and/or the plug 87 if there is such a member) from the radial direction. The channel 82 is removed and a new conductive component 86 is inserted therein. The scope of the present invention is not limited by the number of radial channels 82 provided in the curved CDRs 80a; likewise, the range of the curved CDRs 80a of the present invention is not limited by the number of conductive components. Another CDR embodiment
如圖21A及21B所示之CDR200’之一實施例,如圖示,CDR200’之實施例可經組態,以警告使用者CDR200’已無法適當地自軸體14分散電流至地面。如圖所示之CDR200’之實施例,係藉由利用一指示器導電組件214’以達成之,此指示器導電組件可設於現有之CDR40或整合於現有之CDR40內。於另一實施例中,CDR200’可整合至一鄰近於現有CDR40之分離結構中。CDR200’可設於或用於任何CDR40、80、80a、100、160、200、202之中,而無特別限制。As an embodiment of the CDR 200' shown in Figures 21A and 21B, as illustrated, the embodiment of the CDR 200' can be configured to alert the user that the CDR 200' has been unable to properly dissipate current from the shaft 14 to the ground. The embodiment of the CDR 200' as shown is achieved by utilizing an indicator conductive component 214' that can be placed in an existing CDR 40 or integrated into an existing CDR 40. In another embodiment, the CDR 200' can be integrated into a separate structure adjacent to the existing CDR 40. The CDR 200' may be provided in or used in any of the CDRs 40, 80, 80a, 100, 160, 200, 202 without particular limitation.
於如圖所示之實施例中,指示器導電組件214’、軸體14、第二導電組件216’及其他電子元件等可經組態,以當導電組件214’、216’適當地接觸軸體14時,其可形成一允許電流流經其中之電路。指示器導電組件214’可實質上設置為如前述之其他導電組件86之結構,並可採用指示器接合件214a’及指示器接觸部214b’。同樣地,第二導電組件216’亦可形成有第二接合件216a’與第二接觸部216b’。惟,任何適用於判斷介於指示器216’、214’間之電性接觸之任何結構及/或方法係皆可能的,且軸體14亦可用於CDR200’中,而無特別限制,除非本案申請專利範圍另有界定。In the illustrated embodiment, the indicator conductive component 214', the shaft 14, the second conductive component 216', and other electronic components, etc., can be configured to properly contact the shaft when the conductive components 214', 216' At body 14, it forms a circuit that allows current to flow therethrough. The indicator conductive component 214' can be substantially configured as the other conductive components 86 as previously described, and can employ the indicator engagement member 214a' and the indicator contact portion 214b'. Similarly, the second conductive member 216' may also be formed with a second engaging member 216a' and a second contact portion 216b'. However, any structure and/or method suitable for determining electrical contact between the indicators 216', 214' is possible, and the shaft 14 can also be used in the CDR 200' without particular limitation, except in this case. The scope of patent application is otherwise defined.
電源210’及指示器212’可整合至前述之電路中,以作為當導電組件86無法在正常運作時,可警告使用者之結構/方法。電源210’及指示器212’可以多種方式整合之,以達到此功效。於一實施例中,電源210’係經由指示器導電組件214’、軸體14、第二導電組件216’,而與指示器212’(包含有LED燈)呈電性連接。電源210’可藉由指示器導電組件214’而啟動指示器212’直至電路呈開啟狀態,或當第二導電組件216’不再與軸體14於其對應之接觸部216’、216b’相接處時(意即,當CDR40無法適當第將電流自軸體14分流至地面時)。因此,當LED燈(此實施例之指示器212’)不再亮時,此導電組件86即應更換新。Power source 210' and indicator 212' can be integrated into the aforementioned circuitry as a structure/method that can alert the user when conductive component 86 is not functioning properly. Power source 210' and indicator 212' can be integrated in a variety of ways to achieve this. In one embodiment, the power source 210' is electrically coupled to the indicator 212' (containing the LED light) via the indicator conductive component 214', the shaft body 14, and the second conductive component 216'. The power source 210' can activate the indicator 212' by the indicator conductive component 214' until the circuit is turned on, or when the second conductive component 216' is no longer associated with the corresponding contact portion 216', 216b' of the shaft 14. When connected (ie, when the CDR 40 is unable to properly shunt current from the shaft 14 to the ground). Therefore, when the LED lamp (indicator 212' of this embodiment) is no longer illuminated, the conductive component 86 should be replaced.
於另一實施例中,開關213’可與電源210’及指示器212’電性連接。此些元件可經組態,以當使用者開啟開關213’時,若指示器導電組件214’及第二導電組件216’兩者皆與軸體14正確接觸,則指示器212’將可傳遞資訊。例如,若指示器212’設有LED燈,則當使用者開啟開關213’時,可使此燈發亮。或者,指示器212’可為一音效裝置,或一結合視覺與聽覺之裝置。故,CDR200’並不侷限於特定之指示器212’,且指示器212’可經組態,以警告使用者指示器導電組件214’及第二導電組件216’是否已正確接觸於軸體14。In another embodiment, the switch 213' can be electrically coupled to the power source 210' and the indicator 212'. Such components can be configured such that when the user turns on the switch 213', if both the indicator conductive component 214' and the second conductive component 216' are in proper contact with the shaft 14, the indicator 212' will be transferable News. For example, if the indicator 212' is provided with an LED light, the light can be illuminated when the user turns on the switch 213'. Alternatively, indicator 212' can be a sound device or a combination of visual and audible devices. Thus, CDR 200' is not limited to a particular indicator 212', and indicator 212' can be configured to alert the user whether indicator conductive component 214' and second conductive component 216' have properly contacted shaft body 14. .
於CDR200’之另一實施例中,當指示器導電組件214’及/或第二導電組件216’不再正確接觸軸體14時,指示器212’即可作用,此原理與前述實施例相反。於指示器212’因非正確接觸而作用之實施例中,指示器導電組件214’及/或第二導電組件216’之一者可經組態,進而使其對應之接觸部214b’、216b’受到某程度之磨損時,一輔助件(圖未示)即可與軸體14相接觸。當輔助件與軸體14接觸時,包含有電源210’及指示器212’之電路將形成閉路。或者,具有不同於指示器導電組件214’及/或第二導電組件216’之配置及/或尺寸(如較短)之導電件,亦可設於導電組件214’、216’之一之內部中,故當導電件與軸體14接觸時,指示器212’將可作用。In another embodiment of the CDR 200', when the indicator conductive component 214' and/or the second conductive component 216' no longer properly contact the shaft 14, the indicator 212' is functional, as opposed to the previous embodiment. . In embodiments where the indicator 212' acts due to improper contact, one of the indicator conductive component 214' and/or the second conductive component 216' can be configured to have its corresponding contact portion 214b', 216b When an abrasion is caused to some extent, an auxiliary member (not shown) can be in contact with the shaft body 14. When the auxiliary member is in contact with the shaft 14, the circuit including the power source 210' and the indicator 212' will form a closed circuit. Alternatively, a conductive member having a different configuration and/or size (eg, shorter) than the indicator conductive component 214' and/or the second conductive component 216' may also be disposed within one of the conductive components 214', 216' Therefore, when the conductive member is in contact with the shaft 14, the indicator 212' will function.
CDR200’亦可整合至用於安裝CDR40至設備殼體16上之鎖附件72中。於CDR200’之此實施例中,該特定鎖附件72可與其他連接至CDR200’上之鎖附件72呈電性隔離,以確保其功能之正常。於此實施例中,自軸承12放電至設備殼體16之電流,係可使指示器212’作用之,猶如放電電流流經與CDR200’些接觸之鎖附件72般。The CDR 200' can also be integrated into a lock attachment 72 for mounting the CDR 40 to the device housing 16. In this embodiment of CDR 200', the particular lock attachment 72 can be electrically isolated from other lock attachments 72 attached to the CDR 200' to ensure proper functioning. In this embodiment, the current discharged from the bearing 12 to the device housing 16 causes the indicator 212' to act as if the discharge current flowed through the lock attachment 72 that is in contact with the CDR 200'.
CDR200’之此些或其他實施例亦可具有提他特徵。例如,一無線射頻辨識標籤(RFID標籤,圖未示)可整合至CDR200’之電路中。CDR200’之電路亦可包含一微型PLC,其可用於蒐集與紀錄相關於CDR200’、CDR40、軸承隔離器10及/或設備之多種資料。RFID標籤亦可使多種設備、CDR200’、CDR400及/或軸承隔離器10於任一場合下之維護辨別更為簡化。These or other embodiments of CDR 200' may also have other features. For example, a radio frequency identification tag (RFID tag, not shown) can be integrated into the circuitry of the CDR 200'. The circuitry of CDR 200' may also include a micro PLC that can be used to collect and record a variety of data relating to CDR 200', CDR 40, bearing isolator 10, and/or equipment. The RFID tag also simplifies the maintenance of the various devices, CDR 200', CDR 400 and/or bearing isolator 10 in any situation.

The first embodiment employs an open face, as shown in Figure 22B, as a front perspective view of the fully assembled snap-on CDR 200.
主體210可包含一底座212,其係沿著主體主孔218之軸延伸之,及一主體壁214垂直於底座212延伸之。於此實施例中,主體210可包含徑向外表面215a及徑向內表面215b。藉由緊配設計,徑向外表面215a可直接抵接於設備殼體16上。主體壁214可於其內表面設有一或多個滑輪凹槽216。滑輪217大致上可包含有環狀、低摩擦及/或低磨損之材質,其可設於滑輪凹槽216內,以減少介於主體210與轉子主體220之間之摩擦損失,詳如下。可以理解的是,滑輪217之其他實施例亦可由PTFE或其他合適之材質所製成,而無特別限制。The body 210 can include a base 212 that extends along the axis of the body main bore 218 and a body wall 214 that extends perpendicular to the base 212. In this embodiment, the body 210 can include a radially outer surface 215a and a radially inner surface 215b. The radially outer surface 215a can abut directly against the device housing 16 by a tight fit design. The body wall 214 can be provided with one or more pulley grooves 216 on its inner surface. The pulley 217 can generally include a ring-shaped, low-friction and/or low-wear material that can be disposed within the pulley groove 216 to reduce frictional losses between the body 210 and the rotor body 220, as described below. It will be appreciated that other embodiments of the pulley 217 may also be made of PTFE or other suitable material without particular limitation.
轉子可包含兩個分離元件-轉子主體220與轉子環230。轉子主體220亦可具有大致呈環狀之外型,並具有底座222及設於中心之轉子主體孔228。凸緣221可自底座222徑向向外延伸出。卡扣渠道226可形成於底座222之徑向外表面上,以及驅動環凹槽224可形成於底座222之徑向內表面上。驅動環239可設於驅動環凹槽224內,並可緊密固定環繞於軸體14,以與轉子主體孔228呈同心圓之方式定位之。驅動環239可經組態以將轉子主體220耦接至軸體14上,故使轉子主體220可隨軸體14旋轉之。驅動環239可由任何適合用於特定應用上之材質所製成,其包括但不僅限於碳纖維織物、固態導電段、導電聚合物及/或其組合等。因此,擷取式CDR200之範圍並不受驅動環239之材質所限制。The rotor may comprise two separate elements - a rotor body 220 and a rotor ring 230. The rotor body 220 may also have a substantially annular shape and have a base 222 and a rotor body bore 228 disposed at the center. The flange 221 can extend radially outward from the base 222. A snap channel 226 can be formed on the radially outer surface of the base 222, and a drive ring groove 224 can be formed on the radially inner surface of the base 222. The drive ring 239 can be disposed in the drive ring recess 224 and can be tightly secured around the shaft body 14 to be positioned concentrically with the rotor body bore 228. The drive ring 239 can be configured to couple the rotor body 220 to the axle body 14, such that the rotor body 220 can rotate with the axle body 14. Drive ring 239 can be made of any material suitable for a particular application, including but not limited to carbon fiber fabrics, solid conductive segments, conductive polymers, and/or combinations thereof, and the like. Therefore, the range of the capture CDR 200 is not limited by the material of the drive ring 239.
轉子環230亦可具有環狀外形,並與轉子環形主孔238實質上設於中心上。轉子環230於轉子環230之內軸向表面237a,可設有複數個徑向渠道232。每一徑向渠道232可設有一擷取部232a,以利於導電段116之限位,如前述之CDR40之其他實施例所示。當擷取式CDR200組立完成後,轉子環230之內軸向表面237a可設置為與轉子主體220之凸緣221之內表面相抵接,如圖22C所示。轉子環230亦可設有脊部236環繞於轉子環形主孔238之圓周。The rotor ring 230 can also have an annular shape and be disposed substantially centrally with the rotor annular main bore 238. The rotor ring 230 is disposed within the inner axial surface 237a of the rotor ring 230 and may be provided with a plurality of radial channels 232. Each radial channel 232 can be provided with a capture portion 232a to facilitate the restriction of the conductive segments 116, as shown in other embodiments of the CDR 40 described above. When the snap-on CDR 200 is assembled, the inner axial surface 237a of the rotor ring 230 can be placed in contact with the inner surface of the flange 221 of the rotor body 220, as shown in Figure 22C. The rotor ring 230 can also be provided with a ridge 236 that surrounds the circumference of the rotor annular main bore 238.
導電段116之遠端可設置於徑向渠道232中,且轉子環230可壓設超過轉子主體220之底座222。當轉子環220係壓設超過轉子主體220之底座222之時,位於轉子環230之脊部236可用於扣接至形成於轉子主體200之底座222中之卡扣渠道226,進而使轉子環230與轉子主體220相互銜接,而使轉子環230可隨轉子主體220旋轉之(並亦可隨其後之軸體14旋轉)。因此,導電段116之遠端可銜接於形成於轉子環230內之徑向渠道232中,並可配設介於轉子主體220之凸緣221及轉子環230間,故可切確地將導電段116限位於其中。The distal end of the conductive segment 116 can be disposed in the radial channel 232, and the rotor ring 230 can be pressed over the base 222 of the rotor body 220. When the rotor ring 220 is pressed over the base 222 of the rotor body 220, the ridge 236 at the rotor ring 230 can be used to snap to the snap channel 226 formed in the base 222 of the rotor body 200, thereby causing the rotor ring 230 The rotor body 230 is coupled to the rotor body 220 so that the rotor ring 230 can rotate with the rotor body 220 (and can also rotate with the subsequent axle body 14). Therefore, the distal end of the conductive segment 116 can be coupled to the radial channel 232 formed in the rotor ring 230, and can be disposed between the flange 221 of the rotor body 220 and the rotor ring 230, so that the conductive portion can be accurately Segment 116 is limited to it.
於操作時,主體210大致上呈靜止的,而轉子主體220及轉子環230大致上則隨軸體14轉動之。主體210之底座212上之主體壁214、徑向內表面215a,及轉子環230之環形徑向外表面235可相互作用,以形成一限位腔室223,以供導電段116之非遠端部分定位於其中。轉子主體220與轉子環230之旋轉所產生之離心力,係施於導電段116上,進而使導電段116之一部分與主體210之底座212上之徑向內表面215b相接觸。因此,驅動環239可傳導電荷至轉子主體220,再傳導電荷至轉子環230,並傳導電荷至導電段116,與傳導電荷至主體210,及最後至設備殼體16。In operation, body 210 is substantially stationary, while rotor body 220 and rotor ring 230 generally rotate with shaft 14. The body wall 214, the radially inner surface 215a of the base 212 of the body 210, and the annular radially outer surface 235 of the rotor ring 230 can interact to form a limiting chamber 223 for the non-distal portion of the conductive segment 116. Partially positioned in it. The centrifugal force generated by the rotation of the rotor body 220 and the rotor ring 230 is applied to the conductive segments 116 such that one portion of the conductive segments 116 is in contact with the radially inner surface 215b of the base 212 of the body 210. Thus, the drive ring 239 can conduct charge to the rotor body 220, conduct the charge to the rotor ring 230, conduct the charge to the conductive segments 116, conduct the charge to the body 210, and finally to the device housing 16.

In this embodiment, the rotor generally includes a rotor ring 230. The body 210 can still include a base 212 having a cover interface surface 213 at the end, and a body wall 214 extending radially inward from the base 212, as shown in Figure 23D. The body wall 214 can be provided with at least one pulley groove 216 therein.

於此實施例中,轉子環230可設有至少一徑向渠道232,自環形徑向外表面235延伸至轉子環形主孔238。圖23E係轉子環230之細部圖。區段凹槽234可配置為環繞轉子環形主孔238,並介於兩相鄰之徑向渠道232之間。導電段116可經定位,以使其遠端延伸超過徑向渠道232及其內部,以限位於區段凹槽234之內。於組裝時,轉子環230之內軸向表面237a可抵接於主體壁214,如圖23C,故可於組裝時,提供擷取式CDR200之此實施例之軸向截面。導電段116之定位於區段凹槽234中之部分,可經組態以銜接至軸體14,進而使轉子環230可隨軸體14旋轉之。In this embodiment, the rotor ring 230 can be provided with at least one radial channel 232 extending from the annular radial outer surface 235 to the rotor annular main bore 238. 23E is a detailed view of the rotor ring 230. The segment recess 234 can be configured to surround the rotor annular main bore 238 and between the two adjacent radial channels 232. The conductive segment 116 can be positioned such that its distal end extends beyond the radial channel 232 and its interior to be within the segment recess 234. When assembled, the inner axial surface 237a of the rotor ring 230 can abut the body wall 214, as shown in Figure 23C, so that the axial cross-section of this embodiment of the capture CDR 200 can be provided upon assembly. The portion of the conductive segment 116 that is positioned in the segment recess 234 can be configured to engage the shaft 14 such that the rotor ring 230 can rotate with the shaft 14.
一大致上呈環狀之蓋體240可具有蓋體主孔248實質上形成於該蓋體240之幾何中心。蓋體240可設有至少一滑輪凹槽246於蓋體內軸向表面247a,如圖23C所示,並可供滑輪217定位於其中,已如前述具有可減少摩擦及/或磨損之功效。蓋體240可藉由複數個鎖附件72以銜接至主體210,並穿過設於蓋體240上之孔249,且可對應銜接至設於主體210上之接納部219。當蓋體240銜接至主體210、主體壁214、主體210徑向內表面215b時,及蓋體240之軸向內表面247a可相互作用,以形成限位腔室223,其可供每一導電段116之一部分定位於其中。A generally annular cover 240 can have a cover main aperture 248 formed substantially at the geometric center of the cover 240. The cover 240 can be provided with at least one pulley recess 246 in the cover axial surface 247a, as shown in Figure 23C, and in which the pulley 217 can be positioned, having the effect of reducing friction and/or wear as previously described.

When the cover 240 is coupled to the body 210, the body wall 214, and the radially inner surface 215b of the body 210, the axially inner surface 247a of the cover 240 can interact to form a limiting chamber 223 for each of the conductive A portion of segment 116 is positioned therein.
於擷取式CDR200之其他實施例中,主體210之運作係大致呈靜止的,而轉子環230大致上可隨軸體14旋轉之。因轉子環230之旋轉而產生施於導電段116之離心力,可使導電段116之一部分接觸主體210之底座212上之徑向內表面215b。因此,導電段116可傳遞電荷自軸體流至主體210,並隨後傳遞至設備殼體16。防爆型 CDR In other embodiments of the snap-on CDR 200, the operation of the body 210 is substantially stationary, and the rotor ring 230 is generally rotatable with the shaft 14. Due to the centrifugal force applied to the conductive segments 116 due to the rotation of the rotor ring 230, one of the conductive segments 116 can be brought into contact with the radially inner surface 215b of the base 212 of the body 210. Thus, the conductive segments 116 can transfer charge from the shaft body to the body 210 and then to the device housing 16. Explosion-proof CDR

導電組件259及/或插頭257可似如前述之導電組件86、214’,而與軸體207及/或套筒204呈電性連接。或者,導電組件259亦可包含任何結構及/或方式,以提供可將電流由軸體207及/或套筒204引導至防爆型CDR202之適當導電路徑,且其亦可協助將導電組件259之一部份正確地限位於蓋體270之內。於另一實施例中,插頭257可藉由一般之螺紋以銜接至蓋體270,以利於其拆卸/安裝;惟,任何合適之結構及/或方法皆可適當地用於將插頭257及/或具有蓋體270之導電組件259相銜接,而無特別限制。可以理解的是,導電組件259之一部份可與軸體207相接觸,且其另一部分可同時與定子250及/或蓋體270之一者相接觸,以直接傳導之方式將電流自軸體207經由防爆型CDR202傳遞至設備殼體(圖未示)。蓋體主體276可形成有蓋體軸向突出部274,及鄰設於蓋體主體276之末端之蓋體凹槽273(如圖24D及24E所示)。於此防爆型CDR202之實施例中,主體徑向孔276a之徑向向內部分可與蓋體凹槽273相交錯。蓋體主體276之末端軸向表面可形成有一或多個鎖附件接納部206,以與一或多個鎖附件205相互配合銜接之,以將定子250銜接至蓋體270上,詳如下。The conductive component 259 and/or the plug 257 can be electrically connected to the shaft 207 and/or the sleeve 204 like the conductive components 86, 214' as described above. Alternatively, the conductive component 259 can also comprise any structure and/or manner to provide a suitable conductive path for directing current from the shaft 207 and/or the sleeve 204 to the explosion-proof CDR 202, and which can also assist in the conductive component 259 A portion is correctly confined within the cover 270. In another embodiment, the plug 257 can be coupled to the cover 270 by a generally threaded thread to facilitate its removal/installation; however, any suitable structure and/or method can be suitably used for the plug 257 and/or Or the conductive component 259 having the cover 270 is engaged without particular limitation. It can be understood that one part of the conductive component 259 can be in contact with the shaft body 207, and the other part can be simultaneously contacted with one of the stator 250 and/or the cover body 270 to directly conduct current from the shaft. The body 207 is transferred to the device housing (not shown) via the explosion-proof CDR 202. The cover body 276 can be formed with a cover axial projection 274 and a cover recess 273 (shown in Figures 24D and 24E) adjacent to the end of the cover body 276. In the embodiment of the explosion proof CDR 202, the radially inward portion of the body radial bore 276a can be interleaved with the cover recess 273. The distal axial surface of the cover body 276 can define one or more lock attachment receivers 206 for mating engagement with one or more lock attachments 205 to engage the stator 250 to the cover 270, as described below.
防爆型CDR202之第一實施例亦可包含一與蓋體270相互配合之定子250。介於鄰近於蓋體凹槽273之區域及防爆型CDR202外部之區域間之幾何形體與多種介面表面(亦稱為「火焰路徑」),可經特別設計(如介於定子250與蓋體270間之介面之寬度、長度、轉變區等),進而可通過如前述之標準或其他標準之規定,而無特別限制。一般而言,若火焰及/或火花自防爆型CDR202中產生時,此火焰會自其向外移動。通常,火焰路徑之設計係具有足夠之距離與體積通往防爆型CDR202之外部,故剛火焰離開防爆型CDR202時,此火焰可有效地被降溫,而無法對防爆型CDR202之外界物質(如氣體、蒸氣等)產生燃燒效果。通常,此種設計需要具有較為精密誤差之火焰路徑。The first embodiment of the explosion-proof CDR 202 can also include a stator 250 that mates with the cover 270. The geometry and various interface surfaces (also referred to as "flame paths") between the regions adjacent to the cover recess 273 and the exterior of the explosion-proof CDR 202 can be specially designed (eg, between the stator 250 and the cover 270). The width, length, transition zone, etc. of the interface between the two can be determined by the above-mentioned standards or other standards without particular limitation. In general, if a flame and/or spark is generated from the explosion-proof CDR 202, the flame will move outward therefrom. Usually, the flame path is designed to have sufficient distance and volume to the outside of the explosion-proof CDR202, so that when the flame leaves the explosion-proof CDR202, the flame can be effectively cooled, and the external substance of the explosion-proof CDR202 (such as gas) cannot be , steam, etc.) produce a burning effect. Often, this design requires a flame path with a relatively fine tolerance.

The stator 250 can also include a sub-groove 253 configured to interact with the cover axial projection 274 (as shown in Figures 24D and 24E), such that the contact portion of the conductive component 259 can be disposed in the cover recess 273. And adjacent to the stator groove 253. As previously mentioned, the structure of the plurality of interface channels between the stator 250 and the cover 270 can vary from application to application and can be specifically designed for authentication and/or other certification specifications as described above.
定子250可藉由一或多個鎖附件205銜接至蓋體270,並可穿過設於定子250上之對應孔,及與一或多個設於蓋體主體276上之前述鎖附件接納部206相銜接。一般而言,可以理解的是,防爆型CDR202於大部分應用中,較佳係該定子250可穩固且固定式地銜接至蓋體270。惟,防爆型CDR202之範圍並不因此受限。故,任何合適之可用於將定子250與蓋體270銜接之結構及/或方法係皆可能的,以用於防爆型CDR202之特定應用上,而無特別限制。The stator 250 can be coupled to the cover 270 by one or more lock attachments 205, and can pass through corresponding holes provided in the stator 250, and with one or more of the aforementioned lock attachment receiving portions provided on the cover body 276. 206 is connected. In general, it will be appreciated that in most applications, the explosion-proof CDR 202 is preferably such that the stator 250 can be securely and securely coupled to the cover 270. However, the scope of the explosion-proof CDR 202 is not limited thereby. Accordingly, any suitable structure and/or method for engaging the stator 250 with the cover 270 is possible for a particular application of the explosion proof CDR 202 without particular limitation.
於防爆型CDR202之第一實施例中,套筒204可銜接至軸體207。套筒204可形成有一或多個套筒凹槽204a於其表面上,並於使用時係鄰近於軸體207。O形環209可設於套筒凹槽204a內,以將套筒204銜接至軸體207,並可使套筒204隨軸體207旋轉之。O形環209可由一低阻抗或相對較低阻抗之材質所製成,包括但不僅限於如具有埋設及/或參雜銀及/或鋁材料之矽材質、金屬編織物,其他導電複合物,及/或其組合等。此適用於特定應用上之O形環209,可由位於英國埃塞克斯之布倫特里之肯特龍公司(Kemtron Co.)所提供,其材質包含有一完全硬化之矽及/或氟硅酮(fluorosilicone)並含有高導性粒子所製成,所述粒子可包含但不僅限於銀、鋁、其他金屬複合物、其他導電複合物,及/或其組合等。O形環209可經組態以確保電流之相容性,並可同時提供介於接觸表面間之低接觸電阻。再者,若任何所述驅動環及/或O形環係可用於所述之軸承隔離器及/或CDR之任一實施例中時,此些驅動環及/或O形環亦可依其需求設置之,而無特別限制。In a first embodiment of the explosion proof CDR 202, the sleeve 204 can be coupled to the shaft 207. The sleeve 204 can be formed with one or more sleeve recesses 204a on its surface and in use adjacent to the shaft body 207. An O-ring 209 can be disposed within the sleeve recess 204a to engage the sleeve 204 to the shaft 207 and allow the sleeve 204 to rotate with the shaft 207. The O-ring 209 can be made of a low-impedance or relatively low-impedance material, including but not limited to, a material having a buried and/or doped silver and/or aluminum material, a metal braid, and other conductive composites. And / or a combination thereof. This O-ring 209 for a particular application is available from Kemtron Co. of Braintree, Essex, UK, and is made of a fully hardened crucible and/or fluorosilicone. (fluorosilicone) and made of highly conductive particles, which may include, but are not limited to, silver, aluminum, other metal composites, other conductive composites, and/or combinations thereof, and the like. O-ring 209 can be configured to ensure current compatibility and at the same time provide low contact resistance between the contact surfaces. Furthermore, if any of the drive rings and/or O-rings can be used in any of the embodiments of the bearing isolators and/or CDRs, the drive rings and/or O-rings can also be Requirements are set without special restrictions.
於另一實施例中,套筒204可藉由化學黏著劑與軸體207相銜接,及/或套筒204可經組態為一導電膠帶或其他可自我黏接之部件。於套筒204之其他實施例中,其可緊配設於軸體207上(如干涉緊配方式),或可藉由其他機構鎖附件(如螺絲、螺栓等)、焊接及/或其他前述之組合等,以與其銜接之。因此,防爆型CDR202之範圍並不受套筒204之存在與否而受限,同時,若當配置有套筒204時,其用於切確將套筒204銜接至軸體207之具體結構及/或方法,並非用於限制防爆型CDR202之範圍,除非本案申請專利範圍另有界定。當定子250與蓋體270係彼此銜接時,於防爆型CDR202之第一實施例之套筒204之長度,係大致等同於防爆型CDR202之軸向尺寸,其中,該套筒204於軸向尺寸上係略朝防爆型CDR202之外部偏移(如圖24D所示)。In another embodiment, the sleeve 204 can be coupled to the shaft 207 by a chemical adhesive, and/or the sleeve 204 can be configured as a conductive tape or other self-adhesive component.

The combination, etc., to connect with it. Therefore, the range of the explosion-proof CDR 202 is not limited by the presence or absence of the sleeve 204, and at the same time, when the sleeve 204 is disposed, it is used to accurately connect the sleeve 204 to the specific structure of the shaft 207 and / or method, is not intended to limit the scope of the explosion-proof CDR202, unless otherwise defined in the scope of the patent application. When the stator 250 and the cover 270 are coupled to each other, the length of the sleeve 204 of the first embodiment of the explosion-proof CDR 202 is substantially equivalent to the axial dimension of the explosion-proof CDR 202, wherein the sleeve 204 is axially sized. The upper system is slightly offset from the outer side of the explosion-proof CDR 202 (as shown in Fig. 24D).
使用套筒204可具有許多優點。第一,其可允許製造商及/或使用者精確地控制介於導電組件259與旋轉元件(如套筒204、軸體207)間之電性連接處之誤差,以利防爆型CDR202之火焰路徑之設計。第二,使用套筒204亦可允許設計師克服界定火焰路徑無法與軸體207精密加工之問題。軸體207之外表面通常係為不規則、非一致性之表面,或由易受侵蝕、凹洞,及/或其他易劣化之材質所製成。可以理解的是,套筒204於需要在旋轉部件與軸接地裝置之間提供平滑、一致性高之表面之應用上,係相當有用的,其包括但不僅限於如前述之軸承隔離器10及/或CDR40、80、80a、100、160、200’、擷取型CDR200,及/或防爆型CDR202。套筒204可形成有一平滑,一致之外表面,以提供一最佳之表面予導電***件259或其他導電部件相接觸。可以理解的是,將套筒204與軸接地裝置一同使用時,可增加軸接地裝置之效能與使用壽命。The use of sleeve 204 can have a number of advantages. First, it allows the manufacturer and/or user to accurately control the error between the conductive component 259 and the rotating component (such as the sleeve 204, the shaft 207) to facilitate the flame of the explosion-proof CDR 202. The design of the path. Second, the use of the sleeve 204 may also allow the designer to overcome the problem of defining a flame path that cannot be precisely machined with the shaft 207. The outer surface of the shaft 207 is typically an irregular, non-uniform surface or made of materials that are susceptible to erosion, cavities, and/or other degradable materials. It will be appreciated that the sleeve 204 is useful in applications that require a smooth, consistent surface between the rotating component and the shaft grounding device, including but not limited to the bearing isolators 10 and/or as previously described. Or CDRs 40, 80, 80a, 100, 160, 200', capture CDR 200, and/or explosion proof CDR 202. The sleeve 204 can be formed with a smooth, uniform outer surface to provide an optimal surface for contact with the conductive insert 259 or other conductive member. It can be understood that when the sleeve 204 is used together with the shaft grounding device, the performance and service life of the shaft grounding device can be increased.

Other embodiments of the shaft sleeve 204 may include a greater or lesser number of sleeve recesses 204a without particular limitation. Meanwhile, in this embodiment, the height of each end wall is the same as the inner wall, but this structure should not be used as the limit sleeve 204.
如前所述,O形環209可作為驅動環,並可設於每一套筒凹槽204a內。可以理解的是,O形環209可將套筒204銜接至軸體207,進而使套筒204隨軸體207轉動之。亦可理解的是,O形環209可由一低阻抗材質所製成,以使電流能輕易地由軸體207經由O形環209傳遞至套筒204,並可流經軸接地裝置。可以理解的是,O形環209可設於每一套筒凹槽204a內,為於此所述之套筒204並不因此而受限。O形環209可由任何適用於套筒204之特定應用之材質所製成。例如,可以理解的是,於部分實施例中,O形環209可由合成、低阻抗之橡膠或類似橡膠之材質所製成。惟,於O形環209之其他實施例中,其可由金屬塗覆之纖維所製成。因此,O形環209所採用之特定材質不應限制套筒204之範圍。As previously mentioned, the O-ring 209 can act as a drive ring and can be disposed within each of the sleeve recesses 204a. It will be appreciated that the O-ring 209 can engage the sleeve 204 to the shaft 207, thereby rotating the sleeve 204 with the shaft 207. It will also be appreciated that the O-ring 209 can be constructed of a low impedance material such that current can be easily transferred from the shaft 207 to the sleeve 204 via the O-ring 209 and can flow through the shaft grounding device. It will be appreciated that an O-ring 209 can be provided in each of the sleeve recesses 204a, as the sleeve 204 described herein is not so limited. O-ring 209 can be made of any material suitable for the particular application of sleeve 204. For example, it will be appreciated that in some embodiments, the O-ring 209 can be made of a synthetic, low-impedance rubber or rubber-like material. However, in other embodiments of the O-ring 209, it can be made from metal coated fibers. Therefore, the particular material used for the O-ring 209 should not limit the extent of the sleeve 204.

圖28A及28B顯示防爆型CDR202之另一實施例。此實施例係類似於如圖25A及25B所述之實施例,其使用有定子250與轉子260。惟,於此防爆型CDR202之實施例中,定子凹槽253、定子250之軸向與徑向突出部254、255、轉子凹槽263、轉子軸向與徑向突出部264、265、蓋體凹槽273,及蓋體軸向與徑向突出部274、275,係相互作用以形成不同於如圖25A及25B所示之防爆型CDR202之實施例所揭露之火焰路徑。因此,於圖28A及28B顯示防爆型CDR202之實施例中之轉子260,可設有轉子徑向突出部265,其具有轉子軸向突出部264自其延伸出。28A and 28B show another embodiment of an explosion-proof type CDR 202. This embodiment is similar to the embodiment illustrated in Figures 25A and 25B, which uses a stator 250 and a rotor 260. However, in the embodiment of the explosion-proof type CDR 202, the stator groove 253, the axial and radial protrusions 254, 255 of the stator 250, the rotor groove 263, the rotor axial and radial protrusions 264, 265, the cover body The grooves 273, and the cover axially interact with the radial projections 274, 275 to form a flame path that is different from the embodiment of the explosion proof CDR 202 as shown in Figures 25A and 25B. Thus, the rotor 260 of the embodiment of the explosion-proof CDR 202 is shown in Figures 28A and 28B, and may be provided with a rotor radial projection 265 having a rotor axial projection 264 extending therefrom.
圖29A及29B顯示防爆型CDR202之另一實施例。此實施例係類似於如圖25A及25B所述之實施例,其使用有定子250與轉子260。惟,於此防爆型CDR202之實施例中,定子凹槽253、定子250之軸向與徑向突出部254、255、轉子凹槽263、轉子軸向與徑向突出部264、265、蓋體凹槽273,及蓋體軸向與徑向突出部274、275,係相互作用以形成不同於如圖25B及28B所示之防爆型CDR202之實施例所揭露之火焰路徑。因此,於此實施例中之轉子260,可設有延伸至定子凹槽253之轉子徑向突出部265,其中該轉子徑向突出部265之軸向表面係鄰近於定子250之徑向突出部255,且其相反之軸向表面係鄰近於蓋體軸向突出部274。軸承隔離器之其他實施例 29A and 29B show another embodiment of an explosion-proof CDR 202. This embodiment is similar to the embodiment illustrated in Figures 25A and 25B, which uses a stator 250 and a rotor 260.

可以理解的是,電流分流裝置11及/或其部分可一體式地設於定子20之一部分中,或電流分流裝置11及/或其部分可與定子20分離式設置,且後者之銜接方式並無任何限制,除非申請專利範圍另有界定。於軸承隔離器10之一實施例中,電流分流裝置11可為一電流分流環,且具體而言,電流分流裝置11可為一徑向型CDR80,如圖15A及15B所示。惟,電流分流裝置11之其他型態亦可用於軸承隔離器上,包括但不僅限於任何適用於所揭露之電流分流環之組態,且無特別限制,除非申請專利範圍另有界定。於一實施例中,電流分流裝置11可具有相似於如圖21A-21C所示之CDR200’之結構等。於另一實施例中,電流分流裝置11可具有相似於如圖15A及15B所示之CDR80之結構等。因此,如圖30-34所示,所述之「軸承隔離器10」與「電流分流裝置11」之詞係可相互替換的。It can be understood that the current shunting device 11 and/or part thereof can be integrally provided in one part of the stator 20, or the current shunting device 11 and/or part thereof can be disposed separately from the stator 20, and the latter is connected There are no restrictions unless the scope of the patent application is otherwise defined. In one embodiment of the bearing isolator 10, the current shunting device 11 can be a current shunt ring, and in particular, the current shunt device 11 can be a radial type CDR 80, as shown in Figures 15A and 15B. However, other versions of the current shunt device 11 can also be used on the bearing isolator, including but not limited to any configuration suitable for the disclosed current shunt ring, and are not particularly limited unless otherwise defined in the scope of the patent application. In one embodiment, the current shunting device 11 can have a structure similar to that of the CDR 200' shown in Figures 21A-21C. In another embodiment, the current shunting device 11 can have a structure similar to the CDR 80 shown in Figures 15A and 15B, and the like. Therefore, as shown in Figs. 30-34, the terms "bearing isolator 10" and "current shunting device 11" are interchangeable.
圖30、30A、30B、33、33A及34係顯示軸承隔離器10之其他實施例之軸向截面圖。如圖所示,定子20可銜接於設備殼體16,故使定子20大致上不會相對於其移動。定子20之一部分可延伸入設備殼體16中,且此定子延伸入設備殼體16之部分長度可因設於定子20之徑向外表面之肩部而受限之。定子20可藉由一或多個O形環18,以與設備殼體16相銜接,其中每一O形環18可對應於定子O形環凹槽22a,其可形成於定子主體22之於操作時鄰近於設備殼體16之一表面上。惟,定子20可藉由任何合適之方式(其中部分此些合適之方法已揭露於前述之電流分流環40、80、100、160、200’、200、軸承隔離器10及/或防爆型電流分流裝置10’等之多種實施例中,及包括但不僅限於機構鎖附件72、205、15’、化學黏著劑、焊接、干涉緊配及/或其組合等)以固定至設備殼體16上。因此,本發明之範圍並不侷限於任何用於將定子20銜接至設備殼體16之方法及/或結構等,除非本案申請專利範圍另有界定。30, 30A, 30B, 33, 33A and 34 show axial cross-sectional views of other embodiments of the bearing isolator 10. As shown, the stator 20 can be coupled to the device housing 16 such that the stator 20 does not substantially move relative thereto. A portion of the stator 20 can extend into the device housing 16 and a portion of the length of the stator that extends into the device housing 16 can be limited by the shoulders provided on the radially outer surface of the stator 20. The stator 20 can be coupled to the device housing 16 by one or more O-rings 18, wherein each O-ring 18 can correspond to a stator O-ring groove 22a that can be formed in the stator body 22 It is adjacent to the surface of one of the device housings 16 during operation. However, the stator 20 can be disclosed in any suitable manner (some of which are disclosed in the foregoing current shunt rings 40, 80, 100, 160, 200', 200, bearing isolators 10, and/or explosion-proof currents). Various embodiments of the shunt device 10' and the like, and including but not limited to the mechanism lock attachments 72, 205, 15', chemical adhesive, welding, interference fit, and/or combinations thereof, for attachment to the device housing 16 . Thus, the scope of the present invention is not limited to any method and/or structure for engaging the stator 20 to the device housing 16, unless the scope of the patent application is otherwise defined.
轉子30可銜接於軸體14,以使轉子30可隨之旋轉。於一實施例中,轉子30可藉由一或多個O型環18以銜接至軸體14。O形環18兩者皆可用於將定子20銜接至設備殼體16上,且用於將轉子30銜接至軸體14之O形環18可經組態,以使其電阻抗較小於前述之CDR之其他實施例之阻抗。因此,於一實施例中,一或多個O形環18可由矽融合有銀及/或鎳,以用於將轉子30銜接至軸體14,及/或將定子20銜接至設備殼體16。故,其他O形環18及/或密封件17可同樣由一大致上較小之阻抗之材質所製成,因此本發明之範圍並不受其限制,除非本案申請專利範圍另有界定。The rotor 30 can be coupled to the shaft 14 such that the rotor 30 can rotate therewith. In one embodiment, the rotor 30 can be coupled to the shaft 14 by one or more O-rings 18. Both O-rings 18 can be used to couple the stator 20 to the device housing 16, and the O-ring 18 for engaging the rotor 30 to the shaft 14 can be configured to have a lower electrical impedance than the foregoing The impedance of other embodiments of the CDR. Thus, in one embodiment, one or more O-rings 18 may be fused with silver and/or nickel for engaging the rotor 30 to the shaft 14 and/or engaging the stator 20 to the device housing 16 . Therefore, the other O-rings 18 and/or seals 17 can be made of a substantially smaller impedance material, and the scope of the present invention is not limited thereto unless otherwise defined in the scope of the patent application.
定子20可設有定子主體22,其具有一或多個定子軸向及/或徑向突出部26、28自定子主體22延伸出,及/或其可設有一或多個定子軸向及/或徑向凹槽29、29a。定子軸向及/或徑向凹槽29、29a可設於定子主體22、定子軸向突出部26及/或定子徑向突出部28之中。每一定子凹槽29、29a可延伸環繞定子凹槽29、29a之整體部分,故定子凹槽29、29a可為環形凹槽。同時,定子軸向及/或徑向突出部26、28可自定子主體22、定子軸向突出部26、定子徑向突出部28、定子軸向凹槽29及/或定子徑向凹槽29a延伸出。此係示於多個圖式之中,且定子突出部26、28可相互作用以形成定子凹槽29、29a,反之亦然。The stator 20 may be provided with a stator body 22 having one or more stator axial and/or radial projections 26, 28 extending from the stator body 22 and/or which may be provided with one or more stator axial directions and / or radial grooves 29, 29a. The stator axial and/or radial grooves 29, 29a may be provided in the stator body 22, the stator axial projections 26 and/or the stator radial projections 28. Each of the stator recesses 29, 29a can extend around an integral portion of the stator recesses 29, 29a such that the stator recesses 29, 29a can be annular recesses. At the same time, the stator axial and/or radial projections 26, 28 may be from the stator body 22, the stator axial projections 26, the stator radial projections 28, the stator axial grooves 29, and/or the stator radial grooves. 29a extends out. This is shown in a plurality of figures, and the stator protrusions 26, 28 can interact to form the stator grooves 29, 29a and vice versa.
定子20可設有內部排槽21於其內,此內部排槽21可作為一於定子20之內部之潤滑劑通道,以使其回流至設備殼體16。此內部排槽21可與一大致上於內部(相對於設備殼體16而言)之定子徑向凹槽29a相連通。大致上而言,可以理解的是,收集位於內部定子徑向凹槽29a之潤滑劑可經由此內部排槽21,透過重力作用而排出。故,內部定子徑向凹槽29a及/或內部排槽21可與軸承隔離器10之其他部分相互流通,而無特別限制,除非申請專利範圍另有界定。The stator 20 may be provided with an internal sump 21 therein as a lubricant passage in the interior of the stator 20 for returning it to the apparatus housing 16. The inner trough 21 can be in communication with a stator radial groove 29a that is generally internal (relative to the apparatus housing 16). In general, it will be appreciated that the lubricant collected in the inner stator radial groove 29a can be discharged through gravity through the inner groove 21. Therefore, the inner stator radial groove 29a and/or the inner groove 21 may circulate with other portions of the bearing isolator 10 without particular limitation unless otherwise defined in the scope of the patent application.
如圖30A及30B所示,定子20亦可設有定子徑向凹槽29a,用以接納滑輪18a。可以理解的是,滑輪18a、定子20及軸體14可經組態,以使滑輪18a之底部切線大致與軸體14之頂部呈共線。介於定子20與軸體14間相鄰於軸承隔離器10之內部維持於一最小間隔時,兼容式滑輪18a可允許徑向軸體14之某程度之移動及/或其他錯位。此最小間隔可協助潤滑劑霧膜轉換回液態,且其亦可防止過多之油(或其他潤滑劑)進入至介於定子20及轉子30間之任何界面中。滑輪18a可由天然之潤滑性、相對較軟且相對兼容之材質所製成,其包含但不僅限於PTFE。As shown in Figures 30A and 30B, the stator 20 can also be provided with a stator radial groove 29a for receiving the pulley 18a. It will be appreciated that the pulley 18a, the stator 20 and the axle body 14 can be configured such that the bottom tangent of the pulley 18a is substantially collinear with the top of the axle body 14. The compatible sheave 18a may allow some degree of movement and/or other misalignment of the radial axle 14 as the stator 20 and the axle 14 are maintained adjacent to each other within a minimum spacing of the interior of the bearing isolator 10. This minimum spacing assists in the conversion of the lubricant film back to the liquid state, and it also prevents excessive oil (or other lubricant) from entering any interface between the stator 20 and the rotor 30. The pulley 18a can be made of a natural lubricious, relatively soft and relatively compatible material including, but not limited to, PTFE.
定子20可設有一位於外側(相對於設備殼體16而言)之外部排槽27。外部排槽27可提供位於轉子30之一部分之內及/或定子20之大致上外部分之沾汙物之通道,以利於其流出軸承隔離器10。此外部排槽27可與一大致上於外部(相對於設備殼體16)之定子徑向凹槽29a及/或大致上外部轉子徑向凹槽39a,相互流通。於一實施例中,定子徑向凹槽29a可大致上與轉子徑向凹槽39a呈軸向對齊,故使此二凹槽29a、39a可相互作用,以形成一沾汙物凹槽。大致上而言,可以理解的是,收集於外部定子徑向凹槽29a及/或外部轉子徑向凹槽39a之沾汙物及/或其他物質,可經由外部排槽27透過重力作用,以排出之。惟,外部定子徑向凹槽29a、外部轉子徑向凹槽39a及/或外部排槽27,可與軸承隔離器10之其他部分相互流通,而無特別限制,除非本案申請專利範圍另有界定。The stator 20 can be provided with an outer groove 27 on the outside (relative to the device housing 16). The outer trough 27 can provide access to contaminants within one portion of the rotor 30 and/or substantially the outer portion of the stator 20 to facilitate its flow out of the bearing isolator 10. The outer groove 27 can be circulated with a stator radial groove 29a and/or a substantially outer rotor radial groove 39a substantially externally (relative to the device housing 16). In one embodiment, the stator radial grooves 29a can be substantially axially aligned with the rotor radial grooves 39a such that the two grooves 29a, 39a can interact to form a contaminant groove. In general, it can be understood that contaminants and/or other substances collected in the outer stator radial groove 29a and/or the outer rotor radial groove 39a can pass through the outer groove 27 to pass gravity.

The conductive components 86 can be wound around the periphery of the current shunt device 11 at equal intervals, or they can have different settings. It will be appreciated that the optimum number and location of the plurality of electrically conductive components 86 may depend on the different applications of the bearing isolator 10 and/or the current shunt device 11. Although the bearing isolator 10 is circumferentially disposed around the bearing isolator 10 with six conductive members 86, the specific number and/or position of the conductive members 86 should not be construed as limiting the scope of the present invention.

The radial bore 23a can house the conductive component 86, the conductive insert 259 and/or the plugs 87, 257 (if needed), and in a manner similar to the other used for the CDR, current shunt device 11 and/or bearing isolator 10 described above. The embodiments are in the same manner without particular limitation, unless otherwise defined in the scope of the patent application. Each radial bore 23a can include a radial channel frame as described in various different embodiments of the CDRs described above and/or bearing isolators.

如圖30A及30B所示,每一徑向孔23a可自定子20之外表面延伸入定子軸向凹槽29中,其中轉子軸向突出部36可定位於定子軸向凹槽29之一部分內。因此,定子軸向凹槽29及轉子軸向突出部36可相互作用,以形成一接觸渠道15,以供導電組件86之一部分延伸入其內。導電組件86之接觸部86b可與轉子軸向突出部36之一徑向外表面直接接觸,且導電組件86之另一部分可與定子20之一部分直接接觸,以使電流可自轉子30流經導電組件86而至定子20。換言之,導電組件86之第一部份及/或***件259可與轉子30直接接觸,及第二部份及/或***件259可與定子20直接接觸,並可同將電流由軸體14經過軸承隔離器10,而直接傳導至設備殼體16(其可形成一電路)。As shown in Figures 30A and 30B, each radial bore 23a can extend from the outer surface of the stator 20 into the stator axial groove 29, wherein the rotor axial projection 36 can be positioned in one of the axial bores 29 of the stator. Inside. Thus, the stator axial groove 29 and the rotor axial projection 36 can interact to form a contact channel 15 for a portion of the conductive component 86 to extend therein. The contact portion 86b of the conductive component 86 can be in direct contact with one of the radially outer surfaces of the rotor axial projection 36, and another portion of the conductive component 86 can be in direct contact with a portion of the stator 20 such that current can flow from the rotor 30 through the conductive Assembly 86 is to stator 20. In other words, the first portion of the conductive component 86 and/or the insert 259 can be in direct contact with the rotor 30, and the second portion and/or the insert 259 can be in direct contact with the stator 20 and can be used to flow current from the shaft 14. Through the bearing isolator 10, it is conducted directly to the device housing 16 (which can form an electrical circuit).
轉子軸向突出部36可形成有平滑、相對一致之徑向外表面,以提供最佳之表面予導電***件86或其他導電部件與其接觸之。此轉子軸向突出部36之相對一致之徑向外表面可設有轉子徑向凹槽39a於轉子軸向突出部36上,其中轉子徑向凹槽39a之寬度可大致相同或較大於導電組件86之接觸部86b之寬度。一或多個轉子徑向突出部38可自轉子軸向突出部36之相對一致之徑向外表面之任一側延伸出。此些轉子徑向突出部38可用於防止沾汙物滲入至導電組件86與轉子30相接觸之部位(如介於兩個轉子徑向突出部38間之轉子軸向突出部36之相對一致之徑向外表面,其亦係自轉子軸向突出部36延伸出),並可防止碳纖維或其他物質侵入至軸承隔離器10之內。定子20及/或轉子30可設有其他凹槽29、29a、39、39a及/或突出部26、28、36、38,鄰設於介於導電組件86及轉子30之間之接觸部位,或其他位置上而無特別限制,除非本案申請專利範圍另有界定。The rotor axial projection 36 can be formed with a smooth, relatively uniform radially outer surface to provide an optimum surface for the pre-conductive insert 86 or other conductive member to contact. The relatively uniform radially outer surface of the rotor axial projection 36 may be provided with a rotor radial groove 39a on the rotor axial projection 36, wherein the rotor radial groove 39a may have a width that is substantially the same or larger than the conductive component The width of the contact portion 86b of 86. One or more rotor radial projections 38 may extend from either side of a relatively uniform radially outer surface of the rotor axial projection 36. Such rotor radial projections 38 can be used to prevent ingress of contaminants into the portion of the conductive assembly 86 that is in contact with the rotor 30 (e.g., the relative axial extent of the rotor axial projections 36 between the two rotor radial projections 38). The radially outer surface, which also extends from the rotor axial projection 36, prevents carbon fibers or other materials from intruding into the bearing isolator 10. The stator 20 and/or the rotor 30 may be provided with other recesses 29, 29a, 39, 39a and/or protrusions 26, 28, 36, 38 adjacent to the contact portion between the conductive component 86 and the rotor 30.

大致上而言,軸承隔離器10可經組態,以使導電組件86之接觸部86b可直接與轉子30之一部分相銜接,於前所述之其他具體實施例,可以理解的是,於轉子30上提供一表面,以使導電組件之接觸部86b可形成具體接觸時,係有其具有相較於先前技藝之優點。第一,其可允許製造商及/或使用者可精確地控制介於導電組件86及轉子30間之電性接觸之誤差,故相較於導電組件86係與軸體14直接接觸之結構而言,具有較長之導電組件86及/或軸承隔離器10之使用壽命,其亦可避免加工軸體14之精確度欠佳之多種問題。通常,軸體14之外表面係呈不規則、非一致性的,或其可能係由易產生腐蝕、孔洞及/或劣化之材質所製成。可以理解的是,於導電組件86與轉子30之間形成直接接觸,對某些應用上係特別有益的,如導電組件86需與一平滑且較為一致之表面相互接觸之應用上時。第二,此結構可防止氧化層體形成於軸體14上,及/或防止潤滑劑(如油等)沉積於軸體14上,此些現象皆會造成介於軸體14與導電組件86間之導電性降低。In general, the bearing isolator 10 can be configured such that the contact portion 86b of the electrically conductive component 86 can directly engage a portion of the rotor 30, as will be understood in the other embodiments previously described above. A surface is provided on 30 such that the contact portion 86b of the conductive component can form a particular contact with advantages over prior art. First, it allows the manufacturer and/or user to accurately control the electrical contact between the conductive component 86 and the rotor 30, so that the conductive component 86 is in direct contact with the body 14 and is in direct contact with the structure. In other words, having a longer service life of the conductive component 86 and/or the bearing isolator 10 can also avoid various problems of poor precision of the machining of the shaft body 14. Generally, the outer surface of the shaft body 14 is irregular, non-uniform, or it may be made of a material that is susceptible to corrosion, holes, and/or deterioration. It will be appreciated that direct contact between the conductive component 86 and the rotor 30 is particularly beneficial for certain applications, such as when the conductive component 86 is to be in contact with a smooth and relatively uniform surface. Secondly, the structure prevents the oxide layer from being formed on the shaft body 14, and/or prevents lubricant (such as oil) from being deposited on the shaft body 14, and these phenomena are caused by the shaft body 14 and the conductive member 86. The conductivity between the two is lowered.
於另一實施例中,電流分流裝置11(或軸承隔離器10)可經組態,以可設於定子20之外部上,以利於維修及/或維護電流分流裝置11之某些部分。於軸承隔離器10內之導電組件86可配置為可更換式的。換言之,當導電組件86之接觸部86b已磨耗時,或導電組件86應其他原因必須更換時,使用者可將導電組件86自徑向孔23a拆下,並將新的導電組件86***之。一或多個導電組件86及/或插頭87之拆卸與安裝可利用如圖30-34所示之結構,以輕易完成之,而無須將定子20、轉子30及/或軸承隔離器10之其他部分自設備殼體16及/或軸體14相對拆除之。In another embodiment, the current shunt device 11 (or the bearing isolator 10) can be configured to be disposed external to the stator 20 to facilitate servicing and/or maintenance of certain portions of the current shunt device 11. The conductive component 86 within the bearing isolator 10 can be configured to be replaceable. In other words, when the contact portion 86b of the conductive member 86 has been worn, or the conductive member 86 has to be replaced for other reasons, the user can detach the conductive member 86 from the radial hole 23a and insert the new conductive member 86. The disassembly and mounting of one or more of the electrically conductive components 86 and/or the plugs 87 can be accomplished easily using the structure shown in Figures 30-34 without the need to mount the stator 20, the rotor 30, and/or the other of the bearing isolator 10.

The other components of the different embodiments shown in FIG. 21C act together to monitor the correct contact between one or more of the conductive components 86 and the shaft 14 and/or the components (as described in one of the bearing isolators 10) For example, one of its rotors 30).
若軸承隔離器10設有電流分流裝置11,並具有如圖21A、21B、21C所示之CDR200’之類似功能,則可以理解的是,絕緣件202’可設於介於指示器導電組件214’及定子20之間。再者,可與絕緣件202’相銜接之徑向孔23a,可具有不同於與其他導電組件86(其可包括第二導電組件216’)相銜接之徑向孔23a。舉例而言,於一實施例中,對應於絕緣件202’之徑向孔23a之直徑,可大於對應於另一導電組件86之徑向孔23a之直徑。此絕緣件202’可設有非導電套筒,其可與設於定子20內之徑向孔23a相銜接,其中指示器導電組件214’可與設於絕緣件202’內之中心孔相銜接。大致上而言,可以理解的是,傳輸插頭218’可鄰設於對應於指示器導電組件214’之定子20內徑向孔23a,以使傳輸插頭218’可與指示器導電組件214’形成有線接觸,而無須過長之導線。惟,指示器導電組件214’與傳輸插頭218’亦可經組態,而具有無線傳輸硬體,故其並無特別限制,除非本案申請專利範圍另有界定。防爆型電流分流裝置 If the bearing isolator 10 is provided with a current shunting device 11 and has a similar function to the CDR 200' as shown in Figures 21A, 21B, 21C, it will be appreciated that the insulating member 202' can be disposed between the indicator conducting component 214.

Moreover, the radial bore 23a, which can be engaged with the insulator 202', can have a radial bore 23a that is different from the other conductive component 86 (which can include the second conductive component 216'). For example, in one embodiment, the diameter of the radial hole 23a corresponding to the insulating member 202' may be larger than the diameter of the radial hole 23a corresponding to the other conductive member 86. The insulating member 202' can be provided with a non-conductive sleeve that can be engaged with a radial hole 23a provided in the stator 20, wherein the indicator conductive component 214' can be coupled to a central hole provided in the insulating member 202'. .

The deformable materials include, but are not limited to, epoxies, chemical adhesives, ceramics, metals, polymers, and/or combinations thereof, and the like. The geometry and the various interface surfaces extend from the inner region of the explosion-proof current shunt device 10' (eg, one of the stator radial grooves 29a' or adjacent thereto) to the outer region of the explosion-proof current shunt device 10' (usually The so-called "flame path" can be specifically designed (such as width, length, turning, etc., the number and structure of the interface between the stator 20' and the rotor 30') to pass the requirements of the aforementioned standard specifications, or other Standard specifications, etc., without special restrictions.
介於定子20’與定子蓋20a’、定子20’與轉子30’、定子20’與轉子蓋30a’、轉子30’與轉子蓋30a’、轉子蓋30a’與定子蓋20a’、定子20’與導電組件86,及/或定子20’與插頭87之間之介面,可經設計以利用此些元件,其特徵包括但不僅限於內部排槽21’、徑向渠道22a’、接納凹槽24’、定子軸向突出部26’、外部排槽27’、定子徑向突出部28’、定子徑向凹槽29a’、定子軸向凹槽29’、第一軸向介面間隔34a’、第一徑向介面間隔34b’、轉子軸向突出部36’、轉子徑向突出部38’、轉子徑向凹槽39a’、轉子軸向凹槽39’等間之介面、定子蓋20a’之特徵,及/或轉子蓋30a’之特徵。Between stator 20' and stator cover 20a', stator 20' and rotor 30', stator 20' and rotor cover 30a', rotor 30' and rotor cover 30a', rotor cover 30a' and stator cover 20a', stator 20' The interface with the conductive component 86, and/or the stator 20' and the plug 87, can be designed to utilize such components, including but not limited to the inner trench 21', the radial channel 22a', the receiving recess 24 ', stator axial projection 26', outer groove 27', stator radial projection 28', stator radial groove 29a', stator axial groove 29', first axial interface spacing 34a', A radial interface interval 34b', a rotor axial projection 36', a rotor radial projection 38', a rotor radial groove 39a', a rotor axial groove 39', etc., and a feature of the stator cover 20a' And/or features of the rotor cover 30a'.
如圖36及36A所示,於防爆型電流分流裝置10’之一實施例中,介於定子20’與轉子30’間之火焰路徑係自設備殼體16’(意即,圖36及36A之左側)延伸至殼體16’之外部區域,且防爆型電流分流裝置10’可包含多種方向。從左到右,介於定子20’與轉子30’間之介面(此介面可形成介於定子20’與30’間之火焰路徑)係由一開始的軸向方向,在轉子徑向突出部38’之後轉變為徑向方向,及其後再轉變回軸向方向。於定子20’之最末端之軸向上,此介面係經過轉子蓋30a’又再轉變為徑向方向,及最後經由定子徑向突出部28’及設於轉子蓋30a’中之轉子軸向突出部36’而成為軸向方向。可以理解的是,介於轉子30’與轉子蓋30a’間之介面,可適當地密封,以避免火焰路徑沿者此介面延伸之。因此,介於定子20’與轉子30’(及轉子蓋30a’)間之介面,可包含四個直角。惟,介於其之間之介面亦可具有不同之結構組態,不同之角度轉折、不同之轉折數等,而無特別限制,除非本案申請專利範圍另有界定。As shown in Figures 36 and 36A, in one embodiment of the explosion-proof current shunt device 10', the flame path between the stator 20' and the rotor 30' is from the device housing 16' (i.e., Figures 36 and 36A). The left side extends to the outer region of the housing 16' and the explosion-proof current shunt device 10' can comprise a variety of orientations. From left to right, the interface between the stator 20' and the rotor 30' (the interface can form a flame path between the stators 20' and 30') is from the initial axial direction at the radial projection of the rotor After 38', it changes to the radial direction and then back to the axial direction. In the axial direction of the extreme end of the stator 20', the interface is again converted into a radial direction through the rotor cover 30a', and finally axially protruded through the stator radial projection 28' and the rotor provided in the rotor cover 30a'. The portion 36' is in the axial direction. It will be appreciated that the interface between the rotor 30' and the rotor cover 30a' can be suitably sealed to prevent the flame path from extending along the interface. Therefore, the interface between the stator 20' and the rotor 30' (and the rotor cover 30a') may include four right angles. However, the interface between them may have different structural configurations, different angle transitions, different number of transitions, etc., without particular limitation, unless otherwise defined in the scope of the patent application.
一般而言,若火焰及/或火花係於防爆型電流分流裝置10’中產生時,其較佳係令火焰自設備殼體16’及/或軸體14’向外遠離之。大致上,火焰路徑係設計於防爆型電流分流裝置10’之外部區域有足夠之距離與體積,故當火焰離開防爆型電流分流裝置10’時,火焰能足以被冷卻,進而避免於防爆型分流裝置10’之外界物質(如氣體、蒸氣等)之燃燒。通常,如此之設計沿此火焰路徑上,需要有較為微小之誤差。In general, if the flame and/or spark is generated in the explosion-proof current shunt device 10', it is preferred that the flame be directed away from the device housing 16' and/or the shaft 14'. In general, the flame path is designed to have sufficient distance and volume in the outer region of the explosion-proof current shunt device 10', so when the flame leaves the explosion-proof current shunt device 10', the flame energy is sufficient to be cooled, thereby avoiding the explosion-proof shunt The combustion of the material outside the device 10' (such as gas, steam, etc.). Often, such a design requires a relatively small amount of error along this flame path.
