Description

本発明は、一方向クラッチ、特に、外軸の軸方向両面を覆うプレート部材が外軸に配置されている一方向クラッチに関する。   The present invention relates to a one-way clutch, and more particularly to a one-way clutch in which plate members that cover both axial surfaces of an outer shaft are arranged on the outer shaft.

一方向クラッチは、軸部材の外周側に配置された複数のポケット部を有する外軸と、複数のポケット部に収納されたローラ及び弾性部材と、ポケット部の軸方向の一方を覆うように配置されたカバーと、ポケット部の軸方向の他方を覆うように配置されたプレートとを備えている。この一方向クラッチでは、軸部材が特定の一方向に回転するとローラがポケット部や弾性部材などによって移動不能状態となり、ローラは軸部材の動力を外軸に伝達する。一方、軸部材が特定の一方向とは異なる方向に回転するときには、ローラがポケット部の内部で移動可能な状態となっており、このためにローラが外軸に動力を伝達せず空転する。   The one-way clutch is arranged so as to cover an outer shaft having a plurality of pocket portions arranged on the outer peripheral side of the shaft member, a roller and an elastic member housed in the plurality of pocket portions, and one of the pocket portions in the axial direction. And a plate arranged so as to cover the other of the pocket portions in the axial direction. In this one-way clutch, when the shaft member rotates in a specific one direction, the roller becomes immovable due to the pocket portion or the elastic member, and the roller transmits the power of the shaft member to the outer shaft. On the other hand, when the shaft member rotates in a direction different from a specific direction, the roller is in a movable state inside the pocket portion, so that the roller idles without transmitting power to the outer shaft.

このような一方向クラッチにおいて、プレートに設けられた突出部が外軸に設けられた取り付け用の孔に嵌合することで外軸にプレートが取り付けられている（特許文献１参照）。
特開２００３−１７２３７７号公報 In such a one-way clutch, the plate is attached to the outer shaft by fitting a protruding portion provided on the plate into a mounting hole provided on the outer shaft (see Patent Document 1 ).
JP 2003-172377 A

従来の一方向クラッチでは、外軸にプレートを取り付けるために外軸に孔を設け、プレートに外軸の孔に嵌合する突出部を設ける必要がある。このため、外軸及びプレートの両方を加工することが必要であるために加工しにくくなる。   In the conventional one-way clutch, it is necessary to provide a hole in the outer shaft in order to attach the plate to the outer shaft, and to provide a protrusion on the plate that fits into the hole of the outer shaft. For this reason, since it is necessary to process both an outer shaft and a plate, it becomes difficult to process.

本発明の課題は、外軸にプレートを支持するための構造を簡単にすることにある。   An object of the present invention is to simplify a structure for supporting a plate on an outer shaft.

請求項１に記載の一方向クラッチは、軸部材に取り付けられた一方向クラッチであって、外軸と、ローラ及び付勢部材と、カバーと、環状のプレートとを有する。外軸は、軸部材が配置可能な開口を有し、軸部材の外周側に配置され内周部から外周側に窪むように設けられた複数のポケット部を有する。ローラは、複数のポケット部に収納されている。付勢部材は、複数のポケット部に収納されローラを周方向に付勢する。カバーはポケット部の軸方向の一方を覆うように配置されている。プレートは、内周部に、外軸の内周側であって軸部材の外周側に設けられカバー側に突出する複数の突出部を有している。そして、複数の突出部は、ポケット部内周端部の周方向両端部である両側壁部のそれぞれに当接可能に設けられ、プレートと外軸とが相対回転不能になるようにプレートを外軸に支持するとともに、ローラ及び付勢部材がポケット部から脱落するのを防止する。 A one-way clutch according to a first aspect is a one-way clutch attached to a shaft member, and includes an outer shaft, a roller and a biasing member, a cover, and an annular plate. The outer shaft has an opening in which the shaft member can be disposed, and has a plurality of pocket portions that are disposed on the outer peripheral side of the shaft member and are recessed from the inner peripheral portion to the outer peripheral side. The roller is stored in a plurality of pocket portions. The biasing member is housed in the plurality of pocket portions and biases the roller in the circumferential direction. The cover is disposed so as to cover one of the pocket portions in the axial direction. The plate has a plurality of projecting portions provided on the inner peripheral side of the outer shaft and on the outer peripheral side of the shaft member and projecting toward the cover side. The plurality of protrusions are provided so as to be able to abut on both side wall portions which are both ends in the circumferential direction of the inner peripheral end portion of the pocket portion, so that the plate and the outer shaft cannot be rotated relative to each other. The roller and the urging member are prevented from falling off from the pocket portion.

この一方向クラッチでは、ローラは付勢部材によって常に周方向の一方向（第１方向）に付勢されている。そして、軸部材が第１方向に回転すると、軸部材の回転に伴ってローラが第１方向にさらに移動させられる。この状態では、ローラは軸部材と外軸との間に食い込んで移動することができず、軸部材からの動力はローラを介して外軸に伝達される。一方、軸部材が第１方向とは逆の方向に回転すると、軸部材の回転によってローラが付勢部材の付勢力に抗して付勢部材側に移動する。このとき、軸部材とポケット部との間にはローラが動くことのできるスペースがあるために、ローラは軸部材と外軸との間で空転し、動力は軸部材から外軸に伝達されない。   In this one-way clutch, the roller is always urged in one circumferential direction (first direction) by the urging member. When the shaft member rotates in the first direction, the roller is further moved in the first direction as the shaft member rotates. In this state, the roller cannot move between the shaft member and the outer shaft, and the power from the shaft member is transmitted to the outer shaft through the roller. On the other hand, when the shaft member rotates in the direction opposite to the first direction, the roller moves to the biasing member side against the biasing force of the biasing member by the rotation of the shaft member. At this time, since there is a space in which the roller can move between the shaft member and the pocket portion, the roller idles between the shaft member and the outer shaft, and power is not transmitted from the shaft member to the outer shaft.

このような一方向クラッチにおいては、プレートは、このプレートに設けられた複数の突出部を有する支持部によって内側からプレートを外軸に支持でき、プレートを支持するための構造が簡単になる。 In such a one-way clutch, the plate can be supported on the outer shaft from the inside by a support portion having a plurality of protrusions provided on the plate, and the structure for supporting the plate is simplified .

また、ローラ及び付勢部材は突出部によってポケット部から脱落しにくくなる。 Further, the roller and the biasing member are not easily dropped from the pocket portion by the protruding portion.

本発明では、外軸の一側面にプレートを取り付けるための構造が簡単になる。   In the present invention, the structure for attaching the plate to one side surface of the outer shaft is simplified.

図１及び図２に示す一方向クラッチ１は、軸部材２に設けられた一方向クラッチ１であって、軸部材２の外周に設けられた外軸３と、外軸３の内部に配置されたローラ６と、外軸３の内部に配置されローラ６と接触するように設けられたアコーディオンばね７と、外軸３の軸方向の一方の側面を覆うように配置されたカバー８と、外軸３の軸方向の他方の側面を覆うように配置されたプレート９とを有する。   A one-way clutch 1 shown in FIGS. 1 and 2 is a one-way clutch 1 provided on a shaft member 2, and is disposed inside an outer shaft 3 provided on the outer periphery of the shaft member 2 and the outer shaft 3.

外軸３は、軸部材２から動力が伝達される環状の部材であって、内周側には複数のポケット部１１（この実施形態では６個）を有している。また、周方向に等間隔に並べて６個の孔１３が配置されており、隣り合う２つの孔１３の間に合計６個のポケット部１１が配置されている。孔１３は、この一方向クラッチ１を軸部材２との間で動力伝達を行う駆動系の他の部材に取り付けるために、ボルトを貫通させるためのものである。そして、ポケット部１１は隣り合う２つの孔１３の間に配置されている。６個のポケット部１１はそれぞれ同じ形状であるので、以下に１つのポケット部１１についてのみ説明する。   The outer shaft 3 is an annular member to which power is transmitted from the shaft member 2, and has a plurality of pocket portions 11 (six in this embodiment) on the inner peripheral side. Further, six holes 13 are arranged at equal intervals in the circumferential direction, and a total of six pocket portions 11 are arranged between two adjacent holes 13. The hole 13 is for allowing a bolt to pass therethrough in order to attach the one-way clutch 1 to another member of the drive system that transmits power to the shaft member 2. The pocket portion 11 is disposed between two adjacent holes 13. Since the six pocket portions 11 have the same shape, only one pocket portion 11 will be described below.

ポケット部１１は、図１に示すように、外軸３の内周端に内周端から外周側に凹むように設けられており、第１径方向側壁部２１と、第１周方向側壁部２２と、第１径方向側壁部２１と第１周方向側壁部２２とをつなぐ第１つなぎ部２３と、第２径方向側壁部２４と、第２周方向側壁部２５と、第２径方向側壁部２４と第２周方向側壁部２５とをつなぐ第２つなぎ部２６と、第１周方向側壁部２２と第２周方向側壁部２５とをつなぐ第３つなぎ部２７とを有する。第１径方向側壁部２１は、外軸３の内周部から外周部に向かって平面上に形成されている。第１周方向側壁部２２は、ローラ６の外周側が接触する部分であって、アコーディオンばね７が配置されている側からローラ６が配置されている側に向かって徐々に外軸の内周部との距離が短くなるように形成されている。第１つなぎ部２３は、第１径方向側壁部２１と第１周方向側壁部２２とを滑らかにつなぐ部分である。第２径方向側壁部２４は後述するアコーディオンばね７の一端が支持されている部分であって、外軸３の内周部から外周部に向かって径方向に平面上に形成されている。第２周方向側壁部２５は、第１周方向側壁部２２よりも内周側に形成されている。第２つなぎ部２６は第２径方向側壁部２４と第２周方向側壁部２５とを滑らかにつなぐ部分である。第３つなぎ部２７は、第１周方向側壁部２２と第２周方向側壁部２５とを滑らかにつなぐ部分である。   As shown in FIG. 1, the pocket portion 11 is provided at the inner peripheral end of the outer shaft 3 so as to be recessed from the inner peripheral end to the outer peripheral side, and includes a first radial side wall portion 21 and a first circumferential side wall portion. 22, a first connecting portion 23 connecting the first radial side wall portion 21 and the first circumferential side wall portion 22, a second radial side wall portion 24, a second circumferential side wall portion 25, and a second radial direction. It has the 2nd connection part 26 which connects the side wall part 24 and the 2nd circumferential direction side wall part 25, and the 3rd connection part 27 which connects the 1st circumferential direction side wall part 22 and the 2nd circumferential direction side wall part 25. The first radial side wall portion 21 is formed on a plane from the inner peripheral portion of the outer shaft 3 toward the outer peripheral portion. The first circumferential side wall portion 22 is a portion where the outer peripheral side of the roller 6 comes into contact, and gradually increases from the side where the accordion spring 7 is disposed toward the side where the roller 6 is disposed. And the distance is shortened. The first connecting portion 23 is a portion that smoothly connects the first radial side wall portion 21 and the first circumferential side wall portion 22. The second radial side wall portion 24 is a portion where one end of an accordion spring 7 described later is supported, and is formed on a flat surface in the radial direction from the inner peripheral portion of the outer shaft 3 toward the outer peripheral portion. The second circumferential side wall 25 is formed on the inner circumferential side with respect to the first circumferential side wall 22. The second connecting portion 26 is a portion that smoothly connects the second radial side wall portion 24 and the second circumferential side wall portion 25. The third connecting portion 27 is a portion that smoothly connects the first circumferential side wall portion 22 and the second circumferential side wall portion 25.

ローラ６は、複数のポケット部１１の内部に収納された円柱状の部材であって、軸部材２から伝達される動力を外軸３に伝達するための部材である。また、ローラ６はアコーディオンばね７によってポケット部１１の第１径方向側壁部２１側に付勢されている。   The roller 6 is a cylindrical member housed in the plurality of pocket portions 11 and is a member for transmitting the power transmitted from the shaft member 2 to the outer shaft 3. Further, the roller 6 is urged toward the first radial side wall portion 21 side of the pocket portion 11 by the accordion spring 7.

アコーディオンばね７は、複数のポケット部１１のそれぞれに収納されており、ローラ６を周方向に付勢する部材である。アコーディオンばね７は、一端がローラ６と接触しており他端はポケット部１１の第２径方向側壁部２４近傍に位置している。   The accordion spring 7 is housed in each of the plurality of pocket portions 11 and is a member that biases the roller 6 in the circumferential direction. One end of the accordion spring 7 is in contact with the roller 6, and the other end is located in the vicinity of the second radial side wall portion 24 of the pocket portion 11.

カバー８は、ポケット部１１の軸方向の一側面を覆うように配置された部材であって、図２に示すように、ローラ６やアコーディオンばね７が軸方向から抜け落ちないようにするために設けられた環状の板状部８ａと環状の板状部８ａの外周に設けられた円筒部８ｂとを有している。   The cover 8 is a member arranged to cover one side surface of the pocket portion 11 in the axial direction, and is provided to prevent the roller 6 and the accordion spring 7 from falling off from the axial direction as shown in FIG. The annular plate-like portion 8a and the cylindrical portion 8b provided on the outer periphery of the annular plate-like portion 8a are provided.

プレート９は、ローラ６やアコーディオンばね７が軸方向から抜け落ちないようにポケット部１１の軸方向のカバー８が配置されていない方の側面を覆うように配置された環状の部材である。また、内周部にはカバー８側に向かって突出した板状の突出部３０が１２カ所設けられている。この突出部３０は、プレート９の内周端部の一部をカバー側に折り曲げて形成した部分であって、ポケット部１１内周端部の周方向両端部のそれぞれに設けられている。また、突出部３０は、ローラ６がポケット部１１の第１径方向側壁部２１に接触している際に、ローラ６とアコーディオンばね７とにそれぞれ平面部分で接触するように外軸３の内周側であって軸部材２の外周側に配置されている。   The plate 9 is an annular member disposed so as to cover the side surface of the pocket portion 11 on which the axial cover 8 is not disposed so that the roller 6 and the accordion spring 7 do not fall off from the axial direction. Further, twelve plate-like projecting portions 30 projecting toward the cover 8 are provided on the inner peripheral portion. The protrusions 30 are portions formed by bending a part of the inner peripheral end of the plate 9 toward the cover, and are provided at both ends in the circumferential direction of the inner peripheral end of the pocket portion 11. Further, when the roller 6 is in contact with the first radial side wall portion 21 of the pocket portion 11, the protruding portion 30 is formed in the outer shaft 3 so as to come into contact with the roller 6 and the accordion spring 7 at a planar portion. It is arranged on the outer circumferential side of the shaft member 2 on the circumferential side.

次に動作について説明する。   Next, the operation will be described.

軸部材２が外軸３に対して図１に示すＲ方向に相対回転すると、軸部材２の回転によってローラ６がポケット部１１の第１径方向側壁部２１側に移動する。すると、図４に示すように、ポケット部１１の第１径方向側壁部２１と軸部材２の外周面との間に噛み込んで、軸部材２と外軸３とによってローラ６の移動が規制される。これにより、軸部材２のトルクが外軸３にローラ６を介して伝達される。   When the shaft member 2 rotates relative to the outer shaft 3 in the R direction shown in FIG. 1, the roller 6 moves to the first radial side wall portion 21 side of the pocket portion 11 by the rotation of the shaft member 2. Then, as shown in FIG. 4, the movement of the roller 6 is regulated by the shaft member 2 and the outer shaft 3 by being engaged between the first radial side wall portion 21 of the pocket portion 11 and the outer peripheral surface of the shaft member 2. Is done. Thereby, the torque of the shaft member 2 is transmitted to the outer shaft 3 via the roller 6.

逆に、軸部材２が外軸３に対してＲの逆方向に相対回転すると、軸部材２の回転によってローラ６がアコーディオンばね７の付勢力に抗してポケット部１１の第２径方向側壁部２４側に移動する。すると、図３に示すように、ポケット部１１の第１周方向側壁部２２と軸部材２の外周面との間に隙間が形成され、ローラ６が第１周方向側壁部２２側に移動する。このようにして軸部材２と外軸３とがフリー状態となる。これにより、軸部材２が空転しトルク伝達が遮断される。   On the other hand, when the shaft member 2 rotates relative to the outer shaft 3 in the direction opposite to R, the rotation of the shaft member 2 causes the roller 6 to resist the biasing force of the accordion spring 7 and the second radial side wall of the pocket portion 11. Move to the part 24 side. Then, as shown in FIG. 3, a gap is formed between the first circumferential side wall portion 22 of the pocket portion 11 and the outer circumferential surface of the shaft member 2, and the roller 6 moves to the first circumferential side wall portion 22 side. . In this way, the shaft member 2 and the outer shaft 3 are in a free state. Thereby, the shaft member 2 idles and torque transmission is interrupted.

この一方向クラッチ１を軸部材２に取り付ける際には、プレート９の突出部３０が外軸３の内周側に配置されプレート９が外軸３に支持される。このために、この一方向クラッチ１を軸部材２に取り付けやすくなる。また、ローラ６及びアコーディオンばね７のポケット部１１内部からの脱落が突出部３０によって防止されている。このために、軸部材２に一方向クラッチ１を取り付ける際にポケット部１１内からローラ６やアコーディオンばね７が脱落しにくくなる。
（３）他の実施例
上記実施例では、突出部をローラ６とアコーディオンばね７とにそれぞれ平面で接触するように配置したが、図６及び図７に示すように、突出部をローラ６とアコーディオンばね７とにそれぞれ側部で接触するように突出部３１及び突出部３２などを配置しても良い。 When the one-way clutch 1 is attached to the shaft member 2, the protruding portion 30 of the plate 9 is disposed on the inner peripheral side of the outer shaft 3 and the plate 9 is supported by the outer shaft 3. For this reason, it becomes easy to attach this one-way clutch 1 to the shaft member 2. Further, the protrusion 30 prevents the roller 6 and the accordion spring 7 from falling out of the pocket portion 11. For this reason, when attaching the one-way clutch 1 to the shaft member 2, the roller 6 and the accordion spring 7 are not easily dropped from the pocket portion 11.
(3) Other Embodiments In the above embodiment, the protrusions are arranged so as to be in contact with the roller 6 and the accordion spring 7 in a plane, respectively. However, as shown in FIGS. You may arrange | position the protrusion part 31, the protrusion part 32, etc. so that it may contact with the accordion spring 7 by a side part, respectively.
