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 and a two-stage machine tool gear, each of which has 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 the planetary shape is known from the prior art. The example here is the gear of the applicant's construction series ZF-Duo Project 2K. Two planetary machine tool gears of this type 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 documents DE 10 2011 013 887 A1, DE 101 55 581 A1 and DE 10 2004 011 361 C5. This type of clamping coupler is also called a clamping hub. The clamping coupler has one or more stop elements that prevent a clamping ring from rotating relative to a coupling shaft, and / or the clamping coupler has a stopper in the clamping ring for a clamp. Tight bolts are used, and the stopper prevents the clamping bolt from rotating out of the clamping ring. With the stopper, the clamping ring can also be expanded elastically, making the installation of the clamping coupler easier.
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 object of the present invention is to improve the above-mentioned prior art, and this object is achieved by the characteristics of the main claim item, and the preferred implementation form can be inferred from the attached claim item.
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, comprising: a coupling shaft having an accommodating area capable of being elastically deformed to accommodate a second shaft; and a clamping ring assembled in the accommodating area. The periphery of the coupling shaft; at least one clamping bolt that can be bolted into the clamping ring to clamp it on the coupling shaft and thus narrow the receiving area; and a stop element that 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 invention is characterized in that the stop element is assembled in the opening of the accommodating area, so that the clamping ring and the coupling shaft can be fixed and rotated with each other. The relative rotation between the clamping ring and the coupling shaft has thus been prevented. In this way, the stop element has a follow-up function, and when the clamping bolt is rotated out, the required loss protection and stop functions are required; The required rotation protection on this coupling axis / 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 receiving area of the coupling shaft at least in the surrounding direction. The aforementioned positioning method can be a card insertion and assembly method, which prevents 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 rotation direction, and the stop element and the opening of the receiving area are inserted into the card and assembled The interconnections 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 formed in particular by a ring with radial slits, which just has a clamping bolt. The clamping bolt is connected to a clamping surface of the ring on two sides of the clamping slit. By the clamping of the clamping bolt, the ring can be elastically narrowed to apply the required clamping force to the receiving 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. By the rotation of the stop element and abutment, the clamping ring can be elastically enlarged. The slits of the clamping ring are thus enlarged and the slit faces are moved 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 sections, each ring section being connected to a clamping bolt, respectively. 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 middle" currently refers in particular to a directional axis (middle) which is positioned at right angles to the rotation axis of the clamping coupler, in particular the coupling shaft, and the The rotation axes intersect. The rotating shaft can simultaneously form a longitudinal axis of the clamping coupler. In contrast, "longitudinal direction" or "longitudinal direction" means in particular a directional axis (center), which is positioned parallel or coaxial to 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 formed in particular as a single part. The stop element projects in particular in the radial direction via the clamping ring and projects inwardly into the opening of the receiving area. The stop element can in particular be screwed into the clamping ring. The clamping ring then 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. The openings in the receiving area are in particular not provided with threads or without 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, such as 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 extend over only a portion of the total length of the shaft of the stop element. In particular, no thread can be provided in the part of the stop element which protrudes or should protrude in the opening of the receiving area. The part is formed particularly smoothly, for example, into 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 so as to be able to move into the opening in the radial direction, ie 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 receiving area of the coupling shaft can have a drilled hole to receive the second shaft. The coupling shaft can therefore be inserted on the second shaft using the receiving area. The receiving area can dominate the slit, for example. This contributes to the flexibility of the receiving area. The receiving area can, for example, control a longitudinal slit or a slit in the form of a bolt / a slit extending transversely to the longitudinal direction. The longitudinal slits extend in the longitudinal direction of the coupling shaft, and the other slits extend transversely to the longitudinal direction. The plurality of slits can be opened toward the front side of the coupling shaft, that is, open to the front side. A plurality of slits can also be formed in the form of long holes. The 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 an opening in the accommodating area, and the opening can be a special opening of the stop element. The opening can therefore only be used for intrusion of the stop element. The size of the opening is therefore adjusted precisely according to the stop element. The opening can be a drilled hole, such as a channel or pocket hole. The opening can also be formed by an opening already existing in the receiving area. In addition, the opening can be formed by a slit in the accommodating area that provides 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。 It is also suggested that a switchable planetary gear governs the gear housing with the drive shaft rotatably arranged in the gear housing and the driven shaft rotatably arranged in the gear housing, the drive shaft being at least rotatably connected with a The sun gear is connected, and the driven shaft is at least rotatably connected to a planet 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 to 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 that the driven shaft can be fixedly connected to the planetary carrier, or the driven shaft and the planetary carrier can be formed in a single piece, that is, they 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 in particular in the gear housing to be rotatable. The planetary gear additionally governs a sleeve capable of moving at least in the first and second switching positions. The sleeve can rotatably connect the hollow gear with the gear housing in a first switching position, and the sleeve can rotatably connect the hollow gear with the drive shaft in a 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 thus fixedly connected to the gear housing during rotation, 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 casing. In this first switching position, the gear has a transmission ratio (i ≠ 1) that is not equal to one.
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 during rotation, the planetary gear is blocked. The hollow gear, the sun gear and the planetary carrier can then continuously rotate only in the same direction with the same number of revolutions. In the second switching position, the gear therefore has a transmission ratio (i = 1) equal to one.
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 driving shaft of the planetary gear forms the coupling shaft of the clamping coupler. The drive shaft thus governs the receiving area, on which a 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, a suggested clamping coupler can also be provided for the planetary gear follower in addition or in another way. 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 receiving area of the coupling shaft is in particular for receiving a drive motor shaft (for example, an electric (E) -mechanical) drive motor shaft. The drive motor shaft is therefore in particular a rotor shaft of the electromechanical device.
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 thus form a flange to mount (eg, latch) the electro-mechanical. The gear housing can govern 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 disposed on the gear housing and the rotor shaft is disposed in the receiving area of the driving 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 governs a sealed internal space. A sleeve, a hollow gear, a sun gear, a planetary gear and a planetary carrier are arranged inside the internal space. This internal space is preferably filled with a lubricating material. The drive shaft / coupling shaft protrudes from the sealed internal space. Here, a shaft washer is arranged between the drive shaft / coupling shaft and the gear housing, for example, a radial shaft seal ring. The design here is that the receiving area is arranged outside the sealing area and has a clamping bolt. Therefore, the gear housing can be filled with a lubricant in advance. The drive motor can be arranged on the gear housing without additional filling measures later. The drive shaft / coupling shaft is therefore sealed by the shaft washer. 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 holds a sleeve in a first switching position and / or a second switching position. The fastener produces a retaining force. In the present case, the holding force acts directly on the sleeve, which holds the sleeve in the respective switching position. When the holding force is too large, the sleeve can be moved out of the respective switching position. The movement of the sleeve to the switching position is preferably achieved by an actuator, or 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 idle position, which serves as the third switching position. In this idling position, the hollow gear can rotate freely in the gear housing, so that the planetary gear can be idled. The sleeve can have a mechanical fastener that keeps the sleeve in the idle position. Therefore, parts of the fastener, especially elastic pressure fittings, 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 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。 This machine tool gear is used in a machine tool and transfers the rotational momentum and speed provided by the drive motor to the mandrel of the machine tool. The mandrel can carry, for example, a tool or a workpiece for processing. The machine tool is, for example, a rotary machine or a milling or 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 formed precisely in a two-stage form. Therefore, it happens to have two gear ratio conversion stages. The gear ratio in the gear ratio conversion stage can be, for example, i = 5 (the first gear ratio conversion stage; the first switching position of the sleeve) and i = 1 (the second gear ratio conversion stage; the second sleeve switching position).

In addition, the bearing cover 4A faces the driving motor to seal the internal space of the gear housing 4, and the driving shaft 1 has an accommodation area 1A for the rotor shaft of the driving motor, and the rotor shaft can be inserted into the accommodation In the zone 1A, the clamping coupler 16 is used for: the rotor shaft of the driving motor can be fixedly connected to the driving shaft 1 and can be rotated through clamping.
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 FIG. 1 again, the driving shaft 1 is fixedly connected to at least one sun gear 6 and can be rotated, for example, the card is inserted and assembled, and the driving shaft 1 and the sun gear 6 can also be connected to each other. The single pieces are formed together, for example, integrally formed or connected to each other by bonding or welding. The sun gear 6 is connected to a plurality of planetary gears 7 in a gear shape. The planetary gear 7 is also rotatably disposed on a planetary carrier 8. The planetary gear 7 is rotatably located on a planetary bolt 8A of a planetary carrier 8, and the planetary carrier 8 is fixedly connected to at least a driven shaft 2 so as to be rotatable, so as to be connected to each other by a card or an assembly method. In addition, the driven shaft 2 and the planetary carrier 8 can also be constituted together in a single piece, for example, integrally formed or connected to each other in a bonding or welding manner. The planetary carrier 8 is currently rotatably positioned in the gear housing 4 via the rolling bearing 5 of the driven shaft 2.
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 FIG. 1, the planetary gear 7 is connected with the hollow gear 9 of the planetary gear 7 in a gear shape. The hollow gear 9 is rotatably positioned in the gear housing 4 via at least one rolling bearing 10. The hollow gear 9 controls the front head 9A, and a coupling member 9B is provided on the head 9A. The coupling member 9B enables the hollow gear 9 to be movably fixedly connected to the sleeve 11 and can rotate. Therefore, the sleeve 11 dominates a corresponding coupling member 11A, and is connected to the coupling member 9B in a card insertion and assembly manner.
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 FIG. 1 again, the sleeve 11 is coaxial and positioned with the driving shaft 1. The sleeve 11 can also be called a switching sleeve, which can switch the gear stage of the planetary gear 7. The sleeve 11 can be moved in at least a first switching position and a second switching position, and can be moved in each of the first and second switching positions. The sleeve 11 communicates with the via the coupling members 9B, 11A. The hollow gear 9 is rotatably connected.
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。 Taken on, in the planetary gear 7, wherein the sleeve 11 is disposed in the second switching position, through the coupling members 9B, 11A and the coupling member 1B of the drive shaft 1, the sleeve 11 The hollow gear 9 is rotatably connected to the drive shaft 1. Therefore, in the first switching position (not shown), the sleeve 11 allows the hollow gear 9 to be rotatably connected to the gear housing 4. Therefore, the sleeve 11 has the second coupling member 11B, and the second coupling member 11B can work with the coupling member 4B corresponding to the gear housing 4 in the first switching position, and the sleeve 11 faces The second switching position moves in the direction of the driven shaft 2.
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。 FIG. 1A shows the area Z marked in FIG. 1 in an enlarged view. Each of these coupling members 1B, 4B, 11A, 11B can be seen well in this figure.
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 sleeve 11, the sleeve 11 is rotatably decoupled by the driving shaft 1. Each of these coupling members 1B, 11A therefore does not interact. The driving shaft 1 is rotatable relative to the sleeve 11 fixed to the gear housing 4.
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。 In the second switching position of the sleeve 11 (see FIG. 1), the sleeve 11 is rotatably decoupled by the gear housing 4. Each of these coupling members 4B, 11B therefore does not interact. The sleeve 11 can thus be rotated together with the drive shaft 1 relative to the fixed gear housing 4.
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 FIG. 1A again, the sleeve 11 is provided with an idle position as a third switching position, wherein the sleeve 11 and the hollow gear 9 are neither connected to the drive shaft 1 nor to the gear housing 4 can be connected rotatably. Therefore, the planetary gear is idling. The third switching position can be a center position of the sleeve 11, which is located between each of the first and second switching positions. In addition, the sleeve 11 is currently moved to the switching position by a driving element 12. The driving element 12 is, for example, a switching fork. The driving element 12 intrudes into the guide groove 11C of the sleeve 11 with an intruding portion 12A. Therefore, the movement of the driving element 12 can be transferred to the rotatable sleeve 11. The guide groove 11C and the intruding portion 12A form a rotary coupler.
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。 The driving element 12 is moved by an actuator 14 set on the gear housing 4. Therefore, a suitable way is that it involves an electromagnetic or an electric actuator 14. Alternatively, a hand lever or the like can be provided to manually move the driving element 12.
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中與該壓該力件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。 Please refer to FIG. 1A, the sleeve 11 has a mechanical fastener 15 that holds the sleeve 11 at each of the first and second switching positions, and can also choose to maintain the sleeve 11 at the third switching position. This fastener is currently formed on the one hand by the elastic pressure member 15A in the hollow gear 9 and on the other hand by the sleeve 11 corresponding to the pressure member 15A and used for the first switching position. A groove 15B and a second groove 15C corresponding to the pressure member 15A in the sleeve 11 for the second switching position are formed (see FIG. 1A). For the third switching position, a third groove positioned between each of the first and second grooves 15B, 15C can still be provided, and the fastener 15 causes a holding force to act on each of the switching positions. In order to move the sleeve 11 to another switching position on the sleeve 11, the holding force must be overcome.
第2圖和第3圖係顯示第1圖之行星齒輪中所使用的夾緊耦合器,第2圖係顯示已組裝完成的狀態中之夾緊耦合器,第3圖則係顯示該夾緊耦合器之分解圖。 Figures 2 and 3 show the clamping coupler used in the planetary gear of Figure 1, Figure 2 shows the clamping coupler in the assembled state, and Figure 3 shows the clamping Exploded view of coupler.
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。 Please refer to FIG. 3, in the planetary gear, the driving shaft 1 simultaneously forms a coupling shaft of the clamping coupler. The rotation axis / longitudinal axis of the clamping coupler, in detail, is the coupling axis / driving shaft 1 of the clamping coupler, which is indicated by a reference symbol L.
在第1圖中,具有容納區1A之驅動軸/耦合軸1由該齒輪殼體4之密封的內部空間突出。該容納區1A以及該夾緊耦合器16之夾緊環18和一夾緊螺栓19位於密封的內部空間外部。 In FIG. 1, the drive shaft / coupling shaft 1 having the receiving area 1A protrudes from the sealed internal space of the gear housing 4. The receiving area 1A, the clamping ring 18 and a clamping bolt 19 of the clamping coupler 16 are located outside the sealed internal space.
此外,第2圖和第3圖中所示的夾緊耦合器16之能利用性不限於行星齒輪或工具機。取而代之者,該夾緊耦合器16能用於每一種軸-軸-或軸-轂-連接。 The usability of the clamp coupler 16 shown in FIGS. 2 and 3 is not limited to a planetary gear or a machine tool. Instead, the clamping coupler 16 can be used for every shaft-shaft- or shaft-hub-connection.
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。 Briefly described above, the receiving area 1A of the coupling shaft / drive shaft 1 is used for another shaft to be connected to the coupling shaft / drive shaft 1, for example, an electro-mechanical rotor shaft.
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 FIGS. 1 and 2, the receiving area 1A is currently formed by a drilled hole in the coupling shaft / drive shaft 1. This borehole in particular forms a channel borehole. This channel bore can be sealed by a closure, such as a plug. Therefore, for example, the lubricant cannot flow through the coupling shaft / drive shaft 1, and the receiving area 1A is formed with a thin wall surface, and the receiving area 1A further has a slit 17 distributed on the coupling shaft / drive Around the shaft 1, the slit 17 leads to the front side of the coupling shaft / drive shaft 1. By the slit 17, the coupling shaft / drive shaft 1 can be easily in the receiving area 1A, elastically in the diameter. Deformed in the middle, the slit thus contributes significantly to the elastic deformation of the receiving area 1A.
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。 A clamping ring 18 is provided on the receiving area 1A, and the receiving area 1A is assembled in the surrounding direction of the coupling shaft / drive shaft 1. The clamping ring 18 has a radial clamping ring slit 18A. By the clamping ring slit 18A, the clamping ring can be enlarged and narrowed in a peripheral direction. In addition, the clamping ring 18 can have a weight area 23 on which the clamping coupler can be balanced. The receiving area 1A can have a stop 22 or a collar as an axial stop for the clamping ring 18.
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 FIG. 1 and FIG. 2 again, a clamping bolt 19 is bolted into the clamping ring 18. The clamping bolt 19 is connected to a slit surface of the clamping ring 18 formed by the clamping ring slit 18A. By clamping the clamping bolt 19, the clamping ring slit 18A can be elastically narrowed. The clamping ring is then clamped on the receiving area 1A, which causes the receiving area 1A to elastically narrow in the radial direction. Then, a second shaft arranged in the receiving area 1A is fixedly clamped. The second shaft is interconnected with the coupling shaft / drive shaft 1 by a card or an assembly method.
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 FIGS. 1 and 2, a stop element 20 is provided in the region of the head of the clamping bolt 19. The stop element 20 is formed by a bolt, and the stop element 20 is bolted to the clamp. Ring 18. In contrast, the clamping ring 18 and the stop element 20 thus dictate corresponding threads.
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。 It is supported that the stopper element 20 forms a kind of loss protection for the clamping bolt 19. When the clamping bolt 19 is rotated out of the clamping ring 18, the head of the clamping bolt 19 is fixed by the stopper element 20. Stopped, unable to leave and positioned on the stop element 20, and also prevented the clamping bolt 19 from falling out of the clamping ring 18, and by the clamping bolt 19 continuing to rotate, the clamping ring 18 The additional enlargement makes the clamping ring 18 easier to install.
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。 Referring to FIG. 3, the stopper element 20 passes through the clamping ring 18 and penetrates into the opening 21 of the coupling shaft / drive shaft 1 in the receiving area 1A, so that the coupling shaft / drive shaft 1 and the The clamping rings 18 are at least fixed to each other and can rotate. The opening 21 can be a dedicated opening of the stop element 20. Therefore, the stopper element 20 can also prevent the clamping ring 18 from falling in the axial direction, that is, falling along the rotation axis L. Alternatively, one of the plurality of slits 17 can be used as the opening 21. In addition, the clamping ring 18 is no longer fixed by the stop element 20 in the axial direction, and the stop element 20 itself is not fixed in the opening 21 in the radial direction, that is, the stop element 20 itself Can be inserted into this opening 21. Furthermore, the stop element 20 is fixed in the radial direction by the clamping ring 18.
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。 According to the above description, the stop element 20 can protect the function of the clamping bolt 19 from being lost, and the function of the rotation protection and the protection of the clamping ring 18 from being lost.
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 / drive shaft 1 now has a receptacle 24 in its front side remote from the clamping ring 18. The receiving member 24 is used to fix the sun gear 6 there in the embodiment of FIG. 1.
