Abstract:
(EN) There is achieved a reverse input shutoff clutch of which the axial dimension can be reduced and which has a minimal number of components. This reverse input shutoff clutch 1 is configured from an input member 2, an output member 3 disposed coaxially with the input member 2, a pressed member 4 having a pressed surface 10, and an engaging element 5. When rotational torque is inputted to the input member 2, the engaging element 5 moves in a direction away from the pressed surface 10 and transmits the rotational torque to the output member 3 on the basis of the engagement with the input member 2, and when rotational torque is reverse-inputted to the output member 3, the engaging element 5 moves in a direction toward the pressed surface 10 and prevents or minimizes relative rotation between the output member 3 and the pressed member 4 on the basis of the engagement with the output member 3.
(FR) L'invention concerne un embrayage d'arrêt d'entrée inverse dont la dimension axiale peut être réduite et qui comporte un nombre minimal d'éléments constitutifs. Cet embrayage d'arrêt d'entrée inverse 1 est conçu à partir d'un élément d'entrée 2, d'un élément de sortie 3 disposé de manière coaxiale avec l'élément d'entrée 2, d'un élément pressé 4 possédant une surface pressée 10, et d'un élément de mise en prise 5. Lorsque le couple de rotation est appliqué à l'élément d'entrée 2, l'élément de mise en prise 5 se déplace dans une direction opposée à la surface pressée 10 et transmet le couple de rotation à l'élément de sortie 3 sur la base de la mise en prise avec l'élément d'entrée 2, et lorsque le couple de rotation est appliqué en sens inverse à l'élément de sortie 3, l'élément de mise en prise 5 se déplace dans une direction vers la surface pressée 10 et empêche ou réduit au minimum la rotation relative entre l'élément de sortie 3 et l'élément pressé 4 sur la base de la mise en prise avec l'élément de sortie 3.
(JA) 軸方向寸法を短くでき、かつ、部品点数を抑えられる、逆入力遮断クラッチを実現する。逆入力遮断クラッチ1を、入力部材2と、該入力部材2と同軸に配置された出力部材3と、被押圧面10を有する被押圧部材4と、係合子5とから構成する。係合子5は、入力部材2に回転トルクが入力されると、入力部材2との係合に基づき被押圧面10から離れる方向に移動して出力部材3に回転トルクを伝達し、かつ、出力部材3に回転トルクが逆入力されると、出力部材3との係合に基づき被押圧面10に近づく方向に移動して出力部材3と被押圧部材4との相対回転を防止または抑制する。
