Description
本發明涉及一種夾緊耦合器以及一種能切換之行星齒輪(gear)和一種二級式工具機齒輪,其分別具有此種夾緊耦合器。 The invention relates to a clamping coupler, a switchable planetary gear (gear) and a two-stage machine tool gear, which respectively have such a clamping coupler.
行星造型中之二級式工具機齒輪由先前技術中已為人所知。此處的範例是本發明申請人之構造系列ZF-二重奏計劃2K之齒輪。由文件DE 199 17 673 A1,DE 103 48 755 A1和DE 10 2015 100 169 B3中已知此種行星造型的二級式工具機齒輪。 The two-stage machine tool gear in planetary modeling is already known in the prior art. The example here is the gear of the applicant's construction series ZF-Duet Project 2K. Such planetary-shaped two-stage machine tool gears are known from documents DE 199 17 673 A1, DE 103 48 755 A1 and DE 10 2015 100 169 B3.
夾緊耦合器亦已為人所知,例如,由文件DE 10 2011 013 887 A1,DE 101 55 581 A1和DE 10 2004 011 361 C5中已為人所知。此種夾緊耦合器亦稱為夾緊輪轂(hub)。此夾緊耦合器具有一個或多個止動元件,其防止一夾緊環相對於一耦合軸作旋轉,及/或此夾緊耦合器具有一在該夾緊環中的停止器以供一夾緊螺栓使用,該停止器防止該夾緊螺栓由該夾緊環中旋轉出來。藉由該停止器,則該夾緊環亦能彈性地擴大,使該夾緊耦合器之安裝更簡易。 Clamping couplers are also known, for example, from the
本發明的目的是改良上述先前技術,且此目的係藉由主請求項之特徵達成,優先的實施形式則能由附屬的請求項推知。 The purpose of the present invention is to improve the above-mentioned prior art, and this purpose is achieved by the characteristics of the main claim, and the preferred implementation form can be inferred from the subsidiary claim.
本發明之一目的,係提供一種夾緊耦合器,包括:一耦合軸, 其具有一能彈性變形的容納區以容納一第二軸;一夾緊環,其在該容納區中組裝在該耦合軸的周圍;至少一夾緊螺栓,其能栓入至該夾緊環中,以將其夾緊固定在該耦合軸上,且因此使該容納區變窄;及一止動元件,其須配置在該夾緊環中,以防止該夾緊螺栓由該夾緊環中旋轉出來。 An object of the present invention is to provide a clamping coupler, including: a coupling shaft with an elastically deformable accommodating area to accommodate a second shaft; a clamping ring assembled in the accommodating area Around the coupling shaft; at least one clamping bolt that can be bolted into the clamping ring to clamp and fix it on the coupling shaft, thereby narrowing the accommodating area; and a stop element, which It must be arranged in the clamping ring to prevent the clamping bolt from rotating out of the clamping ring.
此外,本發明之特徵為:該止動元件組裝在該容納區之開口中,使該夾緊環和該耦合軸能互相固定而旋轉。該夾緊環和該耦合軸之間的相對旋轉因此已被阻止,如此,該止動元件具有後續功能,該夾緊螺栓在旋轉出來時,所需的遺失保護及停止功能;該夾緊環在該耦合軸/容納區上所需的旋轉保護。 In addition, the feature of the present invention is that the stop element is assembled in the opening of the receiving area, so that the clamping ring and the coupling shaft can be fixed to each other and rotate. Therefore, the relative rotation between the clamping ring and the coupling shaft has been prevented. In this way, the stop element has the follow-up function. When the clamping bolt is rotated out, the required loss protection and stop function are required; the clamping ring Rotation protection required on the coupling shaft/receiving area.
該止動元件能至少在周圍方向中定位在該耦合軸之容納區的開口中,前述定位方式能為嵌卡、組裝方式,防止了夾緊環和耦合軸之間的相對旋轉。如此,夾緊耦合器能達成一種簡易的平衡,此乃因夾緊環和耦合軸在旋轉方向中固定地互相配置著,又,該止動元件和該容納區之開口,以嵌卡、組裝方式互相連接亦能在軸向中延伸。 The stop element can be positioned in the opening of the accommodating area of the coupling shaft at least in the peripheral direction, and the aforementioned positioning method can be an inserting and assembling method, which prevents the relative rotation between the clamping ring and the coupling shaft. In this way, the clamping coupler can achieve a simple balance because the clamping ring and the coupling shaft are fixedly arranged with each other in the direction of rotation. Moreover, the stop element and the opening of the accommodating area can be inserted and assembled. Ways to connect to each other can also extend in the axial direction.
該夾緊環特別是由徑向有狹縫之環形成,其剛好具有一夾緊螺栓。該夾緊螺栓連接著該環之位於該夾緊狹縫之二側的夾縫面。藉由該夾緊螺栓之栓入,能使該環彈性地變窄,以將所需之夾緊力施加至耦合軸之容納區。該夾緊環之狹縫在變窄後,能使狹縫面互相移動或甚至互相靠緊。藉由該止動元件旋轉出來且靠緊,能使該夾緊環彈性地擴大。該夾緊環之狹縫因此擴大,狹縫面互相移開。 The clamping ring is in particular formed by a ring with radial slits, which just has a clamping bolt. The clamping bolt is connected with the clamping seam surfaces of the ring on the two sides of the clamping slit. Through the bolting of the clamping bolt, the ring can be elastically narrowed to apply the required clamping force to the accommodating area of the coupling shaft. After the slits of the clamping ring are narrowed, the slit surfaces can move or even close to each other. The clamping ring can be elastically expanded by the stop element rotating out and being tight. The slits of the clamping ring are therefore enlarged and the slit faces move away from each other.
此外,該夾緊環亦能由二個或更多個環區段形成,各個環區段分別與一夾緊螺栓連接。在此種情況下,能設有複數個該止動元件,特 別是每一夾緊螺栓設有一個。 In addition, the clamping ring can also be formed by two or more ring segments, each of which is connected to a clamping bolt. In this case, a plurality of the stop elements can be provided, especially one for each clamping bolt.
所謂”徑向的”或”徑向中”目前在意義上特別是指一種方向軸(中),其定位成與該夾緊耦合器,特別是該耦合軸,之旋轉軸成直角且與該旋轉軸相交。該旋轉軸同時能形成該夾緊耦合器之縱軸。與此相對,”沿縱的方向”或”縱向中”在意義上特別是指一種方向軸(中),其定位成與該夾緊耦合器之旋轉軸平行或共軸。 The so-called "radial" or "radial center" in the present sense particularly refers to a direction axis (middle), which is positioned at right angles to the rotation axis of the clamping coupler, especially the coupling shaft, and to the axis of rotation. The rotation axes intersect. The rotation axis can simultaneously form the longitudinal axis of the clamping coupler. In contrast, "in the longitudinal direction" or "in the longitudinal direction" in the sense particularly refers to a directional axis (middle), which is positioned parallel or coaxial with the rotation axis of the clamping coupler.
該止動元件特別是以單一部份構成。該止動元件特別是於徑向中經由該夾緊環而突起且向內伸入至該容納區之開口中。該止動元件特別是能栓入至該夾緊環中。於是,該夾緊環具有一種螺紋,例如,內螺紋,且該止動元件具有一種與該內螺紋相對應的螺紋,例如,外螺紋。容納區中的開口特別是未具有螺紋或未具有其它用於該止動元件之徑向固定件。 The stop element is especially constructed in a single part. In particular, the stop element projects in the radial direction via the clamping ring and projects inwardly into the opening of the receiving area. In particular, the stop element can be bolted into the clamping ring. Thus, the clamping ring has a thread, for example, an internal thread, and the stop element has a thread corresponding to the internal thread, for example, an external thread. In particular, the opening in the receiving area has no threads or other radial fixings for the stop element.
該止動元件特別是一種螺栓。該止動元件能具有一種平頭或鑄造頭,例如,六邊頭。該止動元件之軸的直徑能小於該夾緊螺栓之軸的直徑。 The stop element is in particular a bolt. The stop element can have a flat or cast head, for example, a hexagonal head. The diameter of the shaft of the stop element can be smaller than the diameter of the shaft of the clamping bolt.
該止動元件之螺紋能只在該止動元件之軸的總長度之一部份上延伸。特別是,在該止動元件之在容納區之開口中突起或應突起的部份中能不設置螺紋。該部份特別是平滑地形成,例如,形成為圓柱形或圓錐形。因此,該止動元件於徑向中未固定在該開口中。該止動元件因此形成為能在徑向中移動至該開口中,即,該止動元件於徑向中不以該開口或該容納區固定。 The thread of the stop element can only extend over a part of the total length of the shaft of the stop element. In particular, no thread can be provided in the portion of the stop element that protrudes or should protrude in the opening of the accommodating area. This part is particularly smoothly formed, for example, in a cylindrical or conical shape. Therefore, the stop element is not fixed in the opening in the radial direction. The stop element is thus formed to be movable into the opening in the radial direction, that is, the stop element is not fixed in the radial direction by the opening or the receiving area.
該止動元件當然亦能形成為壓力銷釘或彈簧銷釘且壓入至該夾緊環中。 The stop element can of course also be formed as a pressure pin or a spring pin and pressed into the clamping ring.
該耦合軸之容納區能具有一鑽孔以容納第二軸。該耦合軸因此能利用該容納區而插在該第二軸上。該容納區例如能支配該狹縫。這樣對該容納區之彈性有貢獻。該容納區例如能支配縱向夾縫或螺栓形式的夾縫/與縱向成橫向而延伸的夾縫。縱向夾縫在該耦合軸之縱向中延伸,其它夾縫則與縱向成橫向而延伸。複數個夾縫能朝向該耦合軸之正面而敞開,即,通向正面。複數個狹縫亦能形成為長孔的形式。複數個狹縫能朝向正面而敞開,其它狹縫則能形成為長孔。 The accommodating area of the coupling shaft can have a bore to accommodate the second shaft. The coupling shaft can therefore be inserted on the second shaft using the receiving area. The receiving area can dictate the slit, for example. This contributes to the elasticity of the containment area. The receiving area can, for example, dictate a longitudinal slit or a bolt-shaped slit/a slit extending transversely to the longitudinal direction. The longitudinal slit extends in the longitudinal direction of the coupling shaft, and the other slits extend transversely to the longitudinal direction. A plurality of slits can be opened toward the front of the coupling shaft, that is, to the front. A plurality of slits can also be formed in the form of long holes. A plurality of slits can be opened toward the front, and the other slits can be formed as long holes.
該止動元件組裝在該容納區之開口中,該開口能以是該止動元件之一專用的開口。該開口因此只能用於該止動元件之侵入。該開口之空間大小因此準確地依據該止動元件調整。該開口能是一種鑽孔,例如,一種通道鑽孔或袋孔鑽孔。該開口另外亦能由容納區中已存在的開口形成。另,該開口能由該容納區中,提供該容納區之彈性用的狹縫形成。 The stop element is assembled in the opening of the accommodating area, and the opening can be a dedicated opening of the stop element. The opening can therefore only be used for the intrusion of the stop element. The size of the space of the opening is therefore adjusted accurately according to the stop element. The opening can be a drill, for example, a tunnel drill or a bag hole drill. The opening can also be formed by an existing opening in the receiving area. In addition, the opening can be formed by a slit in the accommodating area for providing elasticity of the accommodating area.
亦建議一種能切換的行星齒輪,其以該齒輪殼體中能旋轉地配置著的該驅動軸和能旋轉地配置著的從動軸支配該齒輪殼體,該驅動軸至少能旋轉地與一太陽齒輪連接,該從動軸至少能旋轉地與一行星載體連接。 A switchable planetary gear is also proposed, in which the drive shaft and the driven shaft rotatably arranged in the gear housing dominate the gear housing, and the drive shaft is at least rotatably connected to one The sun gear is connected, and the driven shaft is at least rotatably connected with a planetary carrier.
這包含:該驅動軸能位置固定地與該太陽齒輪連接,或該驅動軸和該太陽齒輪能以單件形式構成,因此,能形成一共同的構件。這亦包含:該從動軸能位置固定地與該行星載體連接,或該從動軸和該行星載體能以單件形式構成,即,能形成一共同的構件。 This includes: the drive shaft can be fixedly connected with the sun gear, or the drive shaft and the sun gear can be formed in a single piece, so that a common component can be formed. This also includes: the driven shaft can be fixedly connected with the planetary carrier, or the driven shaft and the planetary carrier can be formed in a single piece, that is, can form a common component.
所建議的行星齒輪另外具有一中空齒輪,其特別是在該齒輪殼體中設定成能旋轉。該行星齒輪另外支配一至少能在第一和第二切換位 置中移動的套筒。該套筒能在第一切換位置中使該中空齒輪能旋轉地與該齒輪殼體連接,且該套筒能在第二切換位置中使該中空齒輪能旋轉地與該驅動軸連接。 The proposed planetary gear additionally has a hollow gear, which is set to be rotatable in particular in the gear housing. The planetary gear additionally controls a sleeve that can move at least in the first and second switching positions. The sleeve can rotatably connect the hollow gear with the gear housing in the first switching position, and the sleeve can rotatably connect the hollow gear with the drive shaft in the second switching position.
第一切換位置中,該中空齒輪因此在旋轉時與該齒輪殼體固定地連接著,其因此不能再相對於該齒輪殼體而旋轉。因此,該中空齒輪之旋轉動量能支撐在該殼體上。在此種第一切換位置中,該齒輪具有一種不等於1之傳動比(i≠1)。 In the first switching position, the hollow gear is therefore fixedly connected to the gear housing when rotating, and it can therefore no longer rotate relative to the gear housing. Therefore, the rotational momentum of the hollow gear can be supported on the housing. In this first switching position, the gear has a gear ratio not equal to 1 (i≠1).
第二切換位置中,該中空齒輪在旋轉時與該驅動軸連接。由於該驅動軸在旋轉時與該中空齒輪和太陽齒輪連接著,則該行星齒輪被封鎖。該中空齒輪、該太陽齒輪和該行星載體然後能持續地只在相同方向中以相同轉數旋轉。在第二切換位置中,該齒輪因此具有等於1之傳動比(i=1)。 In the second switching position, the hollow gear is connected to the drive shaft when rotating. Since the drive shaft is connected with the hollow gear and the sun gear when rotating, the planetary gear is blocked. The hollow gear, the sun gear and the planet carrier can then continuously rotate only in the same direction at the same number of revolutions. In the second switching position, the gear therefore has a transmission ratio equal to 1 (i=1).
最後,所建議的該行星齒輪亦具有所建議的夾緊耦合器。因此,該行星齒輪之驅動軸形成該夾緊耦合器之耦合軸。該驅動軸因此支配該容納區,該容納區上配置著夾緊環及該夾緊螺栓和該止動元件。 Finally, the proposed planetary gear also has the proposed clamping coupler. Therefore, the drive shaft of the planetary gear forms the coupling shaft of the clamping coupler. The drive shaft therefore dominates the receiving area on which the clamping ring, the clamping bolt and the stop element are arranged.
基本上亦能額外地或以另一方式亦對行星齒輪之從動器設置一種建議的夾緊耦合器。因此,該從動軸形成該夾緊耦合器之所述耦合軸。 Basically, it is also possible to additionally or in another way also provide a suggested clamping coupler for the planetary gear follower. Therefore, the driven shaft forms the coupling shaft of the clamping coupler.
該耦合軸之容納區特別是用於容納一驅動馬達(例如,一種電動(E)-機械)之驅動馬達軸。該驅動馬達軸因此特別是指該電動-機械之轉子軸。 The accommodating area of the coupling shaft is particularly used for accommodating a drive motor shaft of a drive motor (for example, an electric (E)-mechanical) drive motor shaft. The drive motor shaft therefore particularly refers to the electro-mechanical rotor shaft.
該行星齒輪之齒輪殼體因此能形成一種凸緣以安裝(例如, 栓鎖)該電動-機械。該齒輪殼體能支配一個或多個開口,經由該開口能抓住該夾緊耦合器之夾緊螺栓。因此,該夾緊螺栓能由該齒輪殼體之外部栓入至該夾緊環中。特別是須設置該開口,使得在電動-機械設置在該齒輪殼體上,且該轉子軸配置在該驅動軸/耦合軸之容納區中時,該開口能達成抓住之功能。 The gear housing of the planetary gear can therefore form a kind of flange for mounting (for example, latching) the electro-mechanical. The gear housing can control one or more openings through which the clamping bolts of the clamping coupler can be grasped. Therefore, the clamping bolt can be bolted into the clamping ring from the outside of the gear housing. In particular, the opening must be provided so that when the electro-mechanical device is arranged on the gear housing and the rotor shaft is arranged in the accommodating area of the drive shaft/coupling shaft, the opening can achieve a grasping function.
該齒輪殼體優先支配一密封之內部空間。該內部空間之內部配置一套筒、一中空齒輪、一太陽齒輪、一行星齒輪和一行星載體。該內部空間優先以潤滑材料填充。該驅動軸/耦合軸由該密封之內部空間突出。於此,該驅動軸/耦合軸和齒輪殼體之間配置一軸墊圈,例如,徑向軸密封環。此處設計方式為:在密封區的外部配置該容納區,其具有一夾緊螺栓。因此,該齒輪殼體能預先填充潤滑劑。該驅動馬達稍後不需其它的填充措施即能配置在該齒輪殼體上。該驅動軸/耦合軸因此藉由該軸墊圈密封。該墊圈能定位成直接與該容納區相鄰。 The gear housing preferentially dominates a sealed internal space. A sleeve, a hollow gear, a sun gear, a planet gear and a planet carrier are arranged inside the inner space. This internal space is preferably filled with lubricating material. The drive shaft/coupling shaft protrudes from the inner space of the seal. Here, a shaft washer, such as a radial shaft sealing ring, is arranged between the drive shaft/coupling shaft and the gear housing. The design method here is that the receiving area is arranged outside the sealing area, which has a clamping bolt. Therefore, the gear housing can be pre-filled with lubricant. The drive motor can be arranged on the gear housing without other filling measures later. The drive shaft/coupling shaft is therefore sealed by the shaft gasket. The gasket can be positioned directly adjacent to the receiving area.
該行星齒輪之套筒包括一機械扣件,其使一套筒保持在第一切換位置及/或第二切換位置中。該扣件產生一種保持力。目前的情況下,該保持力直接作用在該套筒上,該保持力使該套筒保持在各別的切換位置中。在該保持力過大時,該套筒能另外由各別的切換位置移動出來。該套筒移動至切換位置優先藉由一種作用器達成,以藉由電動馬達之作用器或電磁作用器達成。 The sleeve of the planetary gear includes a mechanical fastener that keeps a sleeve in the first switching position and/or the second switching position. The fastener creates a holding force. In the current situation, the holding force directly acts on the sleeve, and the holding force keeps the sleeve in the respective switching positions. When the holding force is too large, the sleeve can be moved out of the respective switching positions. The movement of the sleeve to the switching position is preferably achieved by an actuator, and by an actuator of an electric motor or an electromagnetic actuator.
能構成該套筒,使其只能移動至第二切換位置。另一方式是該套筒另外仍能移動至一空轉位置,其作為第三切換位置。在此種空轉位置中,該中空齒輪能自由地在該齒輪殼體中旋轉,這樣就能使該行星齒輪 空轉。該套筒能具有一機械扣件,其使套筒保持在空轉位置。因此,該扣件之零件,特別是具彈性之壓力配件,能在第一或第二切換位置時受到保護。 The sleeve can be constructed so that it can only be moved to the second switching position. Another way is that the sleeve can still be moved to an idling position, which serves as the third switching position. In this idling position, the hollow gear can freely rotate in the gear housing, so that the planetary gear can be idling. The sleeve can have a mechanical fastener that keeps the sleeve in the idling position. Therefore, the parts of the fastener, especially the elastic pressure fitting, can be protected in the first or second switching position.
亦建議一種二級式工具機齒輪,其依據所建議的行星齒輪構成。 A two-stage machine tool gear is also proposed, which is constructed based on the proposed planetary gear.
該工具機齒輪使用在工具機中,將由驅動馬達提供的旋轉動量和轉速轉移至工具機之心軸。該心軸例如能承載加工用的工具或工件。工具機例如是旋轉機或銑切機或研磨機或對應的加工中心。 The machine tool gear is used in the machine tool to transfer the rotational momentum and speed provided by the drive motor to the spindle of the machine tool. The mandrel can, for example, carry tools or workpieces for machining. The machine tool is, for example, a rotating machine or a milling machine or a grinding machine or a corresponding machining center.
工具機齒輪特別是準確地以二級形式形成。因此,其恰巧具有二個傳動比轉換級。傳動比轉換級中的傳動比例如能以是i=5(第一傳動比轉換級;該套筒之第一切換位置)和i=1(第二傳動比轉換級;套筒之第二切換位置)。 The machine tool gear is particularly precisely formed in a two-stage form. Therefore, it happens to have two gear ratio conversion stages. The transmission ratio in the transmission ratio conversion stage can be, for example, i=5 (the first transmission ratio conversion stage; the first switching position of the sleeve) and i=1 (the second transmission ratio conversion stage; the second switching of the sleeve) Location).

複請參閱第1圖所示,該驅動軸1至少與一太陽齒輪6固定地連接著而能旋轉,例如嵌卡、組裝方式互相連接,此外,該驅動軸1和該太陽齒輪6亦能以單件形式共同構成,例如一體成形或以黏合、焊接方式互相連接。該太陽齒輪6係與複數個行星齒輪7連接成輪齒形。該行星齒輪7亦能旋轉地配置在一行星載體8上。該行星齒輪7能旋轉地位於一行星載體8之行星螺栓8A上,又,該行星載體8至少與一從動軸2固定地連接著而能旋轉, 以藉由嵌卡或組裝方式互相連接。此外,該從動軸2和該行星載體8亦能以單件形式共同構成,例如一體成形或以黏合、焊接方式互相連接。該行星載體8目前經由該從動軸2之滾動軸承5而能旋轉地定位在該齒輪殼體4之中。 Please refer to Figure 1 again, the
請參閱第1圖所示,該行星齒輪7係與該行星齒輪7之中空齒輪9連接成輪齒形,該中空齒輪9係經由至少一滾動軸承10而能旋轉地定位在該齒輪殼體4中,該中空齒輪9支配正面之頭部9A,在該頭部9A上設有一耦合件9B,該耦合件9B使該中空齒輪9能移動地與該套筒11固定地連接著而能旋轉。因此,該套筒11支配一相對應的該耦合件11A,且以嵌卡、組裝方式而與該耦合件9B互相連接。 Please refer to Figure 1, the
複請參閱第1圖所示,該套筒11係與該驅動軸1共軸且定位著,該套筒11亦能稱為切換套筒,其係能切換該行星齒輪7之齒輪級,該套筒11能在至少一第一切換位置和一第二切換位置中移動,且能推移在各該第一和第二切換位置中,該套筒11經由各該耦合件9B,11A而與該中空齒輪9能旋轉地連接著。 Please refer to Figure 1 again. The
承上,在該行星齒輪7中,其中該套筒11配置在該第二切換位置中,藉由上述各該耦合件9B,11A且藉由該驅動軸1之耦合件1B,該套筒11使該中空齒輪9與該驅動軸1能旋轉地連接著,因此,在未顯示的該第一切換位置中,該套筒11使該中空齒輪9能旋轉地與該齒輪殼體4連接著。因此,該套筒11具有該第二耦合件11B,該第二耦合件11B能在該第一切換位置中與該齒輪殼體4之對應的該耦合件4B一起作用,該套筒11面對該第二切換位置而該從動軸2之方向中移動。 On the other hand, in the
第1A圖以放大圖顯示第1圖中標記的區域Z。各該耦合件1B,4B,11A,11B在此圖能良好地被看到。 Figure 1A shows the area Z marked in Figure 1 in an enlarged view. Each of the
請參閱第1A圖所示,該套筒11之第一切換位置中,該套筒11能旋轉地由該驅動軸1去耦合。各該耦合件1B,11A因此未互相作用。該驅動軸1能相對於與該齒輪殼體4互相固定的該套筒11而旋轉。 Please refer to FIG. 1A, in the first switching position of the
承上,該套筒11之第二切換位置(參閱第1圖)中,該套筒11能旋轉地由該齒輪殼體4去耦合。各該耦合件4B,11B因此未互相作用。該套筒11因此能與該驅動軸1一起相對於固定的該齒輪殼體4而旋轉。 On the other hand, in the second switching position of the sleeve 11 (refer to FIG. 1), the
複請參閱第1A圖所示,該套筒11設置一種空轉位置以作為一第三切換位置,其中該套筒11和該中空齒輪9既不與該驅動軸1且亦不與該齒輪殼體4能旋轉地連接。因此,該行星齒輪處於空轉中。該第三切換位置能以該套筒11之中央位置,其位於各該第一和第二切換位置之間。又,該套筒11目前藉由一驅動元件12而移動至切換位置中。該驅動元件12,例如是一種切換叉。該驅動元件12以一侵入部12A侵入至該套筒11之導槽11C中。因此,該驅動元件12之移動能轉移至能旋轉的套筒11上。該導槽11C和該侵入部12A形成一旋轉耦合器。 Please refer to Figure 1A again. The
承上,該驅動元件12藉由設定在該齒輪殼體4上的一作用器14而移動。因此,適當方式是其涉及一種電磁或一電動作用器14。另一方式是,亦能設置一手桿或類似物件以人工移動該驅動元件12。 In summary, the driving
請參閱第1A圖所示,該套筒11具有一機械扣件15,其將該套筒11保持在各該第一和第二切換位置,且亦能選擇保持在該第三切換位置。此扣件目前一方面由該中空齒輪9中具彈性的壓力件15A形成,且另一方面係由該套筒11中與該壓力件15A對應的,用於該第一切換位置的第一凹槽15B,以及該套筒11中與該壓力件15A對應的,用於該第二切換位置的第二凹槽15C形成(請參閱第1A圖)。對該第三切換位置而言,仍能設置一種定位於各該第一和第二凹槽15B,15C之間的第三凹槽,該扣件15使一種保持力作用在各別切換位置上的該套筒11上,為了將該套筒11移動至另一切換位置,必須克服該保持力。

請參閱第3圖所示,該行星齒輪中,該驅動軸1同時形成該夾緊耦合器之耦合軸。該夾緊耦合器之旋轉軸/縱軸,詳細而言是該夾緊耦合器之耦合軸/驅動軸1,以參考符號L標示。

以上簡述,該耦合軸/驅動軸1之容納區1A係用於即將與該耦合軸/驅動軸1連接的另一軸,例如,電動-機械之轉子軸。
As briefly mentioned above, the
請參閱第1及2圖所示,該容納區1A目前由該耦合軸/驅動軸1中之鑽孔形成。此鑽孔特別是形成一種通道式鑽孔。此通道式鑽孔能藉由封閉件密封,例如,栓塞。因此,例如,潤滑劑不能流經該耦合軸/驅動軸1,又,該容納區1A形成為具有較薄的壁面,該容納區1A另外具有一狹縫17,其分佈在該耦合軸/驅動軸1之周圍,該狹縫17通向該耦合軸/驅動軸1之正面,藉由該狹縫17則該耦合軸/驅動軸1能較容易地在該容納區1A中,彈性地在徑向中變形,該狹縫因此對該容納區1A之能彈性地變形具有重大貢獻。 Please refer to Figures 1 and 2, the receiving
承上,在容納區1A上設置一夾緊環18,其於耦合軸/驅動軸1之周圍方向中組裝該容納區1A。夾緊環18具有一徑向的夾緊環狹縫18A。藉由該夾緊環狹縫18A,使該夾緊環能在能在周圍方向中擴大和變窄。又,該夾緊環18能具有重量區23,其上能使該夾緊耦合器平衡。該容納區1A能具有止檔部22或套環,以作為該夾緊環18用的軸向停止器。 On the other hand, a clamping
複請參閱第1及2圖所示,一夾緊螺栓19栓入至該夾緊環18中。該夾緊螺栓19連接該夾緊環18之由該夾緊環狹縫18A形成的狹縫面。藉由該夾緊螺栓19之栓入,能使該夾緊環狹縫18A彈性地變窄。於是,該夾緊環在容納區1A上夾緊,這樣會造成該容納區1A彈性地在徑向中變窄。於是,配置在容納區1A中的一第二軸被固定地夾緊。此該第二軸以嵌卡或組裝方式與耦合軸/驅動軸1互相連接。 Please refer to FIGS. 1 and 2 again, a clamping
請參閱第1及2圖所示,在該夾緊螺栓19之頭部的區域中設有一止動元件20,該止動元件20係由螺栓形成,該止動元件20栓入至該夾緊環18中。相對於此,該夾緊環18和該止動元件20因此支配著互相對應的螺紋。 Please refer to Figures 1 and 2, a
承上,該止動元件20對該夾緊螺栓19形成一種遺失保護,當該夾緊螺栓19由該夾緊環18旋轉出來時,該夾緊螺栓19之頭部係被該止動 元件20檔住,而無法離開被定位在該止動元件20上,且亦能防止了該夾緊螺栓19由該夾緊環18掉出去,藉由該夾緊螺栓19繼續旋轉,該夾緊環18額外地擴大,能使該夾緊環18更容易安裝。 On the other hand, the
請參閱第3圖所示,該止動元件20穿過該夾緊環18且在容納區1A中侵入至該耦合軸/驅動軸1之開口21中,使該耦合軸/驅動軸1和該夾緊環18至少互相固定著而能旋轉。該開口21能為該止動元件20之專用開口。因此,該止動元件20亦能防止該夾緊環18之軸向掉落,即,沿著旋轉軸L掉落。另一方式是,亦能使用多個狹縫17之一作為開口21。此外,該夾緊環18於軸向中就不再由該止動元件20固定著,又,該止動元件20本身於徑向中未固定在開口21中,即,該止動元件20本身能***至該開口21中。此外,該止動元件20在徑向中由該夾緊環18固定著。 Please refer to Figure 3, the
承上,該止動元件20能保護該夾緊螺栓19遺失之功能、及該夾緊環18旋轉保護和保護遺失之功能。 In addition, the
耦合軸/驅動軸1目前在其遠離該夾緊環18之正面中具有一容納件24。此容納件24在第1圖之實施例中用於在該處固定該太陽齒輪6。 The coupling shaft/
