Title (EN) TORQUE TRANSMISSION SHAFT
(FR) ARBRE DE TRANSMISSION DE COUPLE
(JA) トルク伝達軸
Abstract:
(EN) In order to achieve a torque transmission shaft structure with which whirling of a shaft connected to a torque transmission shaft can be suppressed, this torque transmission shaft 22 comprises: a shaft 23, which has an integrally formed yoke section 25 provided on one end in the axial direction and a female serration 32 provided on an inner circumferential surface on the other end in the axial direction; and a clamp 24 that is a separate body from the shaft 23 and is for reducing the diameter of the other end of the shaft 23 in the axial direction. The shaft 23 and the clamp 24 are joined to each other by welding.
(FR) Afin d'obtenir une structure d'arbre de transmission de couple avec laquelle le tourbillonnement d'un arbre raccordé à un arbre de transmission de couple peut être supprimé, l'arbre de transmission de couple (22) selon l'invention comprend : un arbre (23), qui a une section chape à rotule formée d'un seul tenant (25) disposée sur une première extrémité dans la direction axiale et une dentelure femelle (32) disposée sur une surface circonférentielle interne sur l'autre extrémité dans la direction axiale ; et une pince (24) qui est un corps séparé de l'arbre (23) et est destinée à réduire le diamètre de l'autre extrémité de l'arbre (23) dans la direction axiale. L'arbre (23) et la pince (24) sont reliés l'un à l'autre par soudage.
(JA) トルク伝達軸に接続される軸の振れ回りを抑えることができるトルク伝達軸の構造を実現する。トルク伝達軸22は、一体に形成され、かつ、軸方向一端部に備えられたヨーク部25と、軸方向他端部の内周面に備えられた雌セレーション32とを有する、シャフト23と、シャフト23とは別体で、シャフト23の軸方向他端部を縮径させるためのクランプ24とを備え、シャフト23とクランプ24とが溶接固定されている。
