Title (EN) ROTATION TRANSMISSION DEVICE
(FR) DISPOSITIF DE TRANSMISSION DE ROTATION
(JA) 回転伝達装置
Abstract:
(EN) In order to prevent backlash of internal components incorporated inside a housing even under a large axial load, this rotation transmission device is provided with: a two-way clutch (10) provided between an input shaft (1) and an output shaft (2); an electromagnetic clutch (60) arranged on the other side in the axial direction for controlling the two-way clutch (10); a housing cover (3) for covering these; and a first bearing unit (70) that is provided between the outer surface of the output shaft (2) and the inner surface of a bearing tube (4) provided at one axial end of the housing (3), and that includes a ball bearing having an outer ring (71), an inner ring (72), and balls (73) arranged between the outer ring (71) and the inner ring (72), wherein a line connecting the contact points of the balls (73) and the outer ring (71) and the inner ring (72) is inclined with respect to the radial direction.
(FR) L'invention a pour but d'empêcher le jeu nuisible entre des éléments internes incorporés à l'intérieur d'une enveloppe, même sous une forte charge axiale. À cet effet, le dispositif de transmission de rotation comprend : un embrayage bidirectionnel (10) agencé entre un arbre d'entrée (1) et un arbre de sortie (2) ; un embrayage électromagnétique (60) agencé de l'autre côté dans la direction axiale afin de commander l'embrayage bidirectionnel (10) ; un couvercle d'enveloppe (3) destiné à les recouvrir ; et une première unité palier (70) agencée entre la face externe de l'arbre de sortie (2) et la face interne d'un tube (4) de palier agencé au niveau d'une extrémité axiale de l'enveloppe (3), et comprenant un roulement à billes comportant une bague externe (71), une bague interne (72) et des billes (73) agencées entre la bague externe (71) et la bague interne (72). Une ligne reliant les points de contact des billes (73) avec la bague externe (71) et la bague interne (72) est inclinée par rapport à la direction radiale.
(JA) 大きなアキシアル荷重が負荷された場合でも、ハウジング内に組込まれた内蔵部品のガタツキを防止する。入力軸(1)及び出力軸(2)の間に設けられた2方向クラッチ(10)と、2方向クラッチ(10)を制御するため軸方向他端側に配置された電磁クラッチ(60)と、それらを覆うハウジング(3)とを有し、ハウジング(3)の軸方向一端に設けられた軸受筒4の内面と出力軸(2)の外面との間に、外輪(71)及び内輪(72)と、外輪(71)及び内輪(72)との間に配置されたボール(73)とを有し、ボール(73)と外輪(71)及び内輪(72)との接触点を結ぶ直線がラジアル方向に対して傾斜する玉軸受を含む第一の軸受部(70)を配置した回転伝達装置とした。
