Abstract
(EN)
A power transmitting device (60) is provided with: an electric motor (50) having a rotating shaft (51); an worm gear (43) provided to the rotating shaft (51); a worm wheel (44) meshing with the worm gear (43); and a housing (45) for accommodating the worm gear (43) and the worm wheel (44). A first axis (C1) which is the center of rotation of the worm gear (43) is tilted relative to a second axis (C2) which is the center of rotation of the worm wheel (44) so that the worm wheel (44) can be mounted after the worm gear (43) is mounted to the housing (45).
(FR)
L'invention concerne un dispositif de transmission de puissance (60) comprenant : un moteur électrique (50) ayant un arbre rotatif (51) ; un engrenage à vis sans fin (43) disposé sur l'arbre rotatif (51) ; une roue à vis sans fin (44) qui s'engrène avec la vis sans fin (43) ; et un boîtier (45) destiné à recevoir l'engrenage à vis sans fin (43) et la roue à vis sans fin (44). Un premier axe (C1), qui est le centre de rotation de l'engrenage à vis sans fin (43), est incliné par rapport à un deuxième axe (C2), qui est le centre de rotation de la roue à vis sans fin (44), de sorte que la roue à vis sans fin (44) peut être montée après que l'engrenage à vis sans fin (43) est monté sur le boîtier (45).
(JA)
動力伝達装置(60)は、回転軸(51)を有する電動モータ(50)と、回転軸(51)に設けられるウォームギヤ(43)と、ウォームギヤ(43)と噛み合うウォームホイール(44)と、ウォームギヤ(43)及びウォームホイール(44)を収容するハウジング(45)と、を備え、ウォームギヤ(43)の回転中心である第1軸線(C1)は、ウォームホイール(44)の回転中心である第2軸線(C2)に対して、ハウジング(45)にウォームギヤ(43)が組み付けられた後にウォームホイール(44)を組み付けることが可能となるように傾斜している。
