Title (EN) ELECTRICALLY DRIVEN ACTUATOR
(FR) ACTIONNEUR À COMMANDE ÉLECTRIQUE
(JA) 電動アクチュエータ
Abstract:
(EN) One embodiment of the electrically driven actuator of the present invention is provided with: a motor having a motor shaft extending along a center axis; a speed reduction mechanism connected to the motor shaft; an output section having an output shaft; a rotation detection device for detecting the rotation of the output section; a case; a first bearing for rotatably connecting the motor shaft and the output section; and a second bearing for rotatably supporting the output section relative to the case. A portion of the inner surface of the case, which is located on one axial side of the speed reduction mechanism, is provided with a support cylinder in which the second bearing is fitted. The first bearing, the output section, the second bearing, and the support cylinder are provided at positions overlapping each other when viewed in a radial direction. At least part of the rotation detection device is disposed at a position facing the outside, in the radial direction, of the support cylinder.
(FR) Un mode de réalisation de l'actionneur à commande électrique de la présente invention comprend : un moteur ayant un arbre de moteur s'étendant le long d'un axe central ; un mécanisme de réduction de vitesse relié à l'arbre de moteur ; une section de sortie ayant un arbre de sortie ; un dispositif de détection de rotation permettant de détecter la rotation de la section de sortie ; un boîtier ; un premier palier permettant de relier de manière rotative l'arbre de moteur et la section de sortie ; et un second palier permettant de soutenir de manière rotative la section de sortie par rapport au boîtier. Une partie de la surface interne du boîtier, qui est située sur un côté axial du mécanisme de réduction de vitesse, est pourvue d'un cylindre de support dans lequel le second palier est installé. Le premier palier, la section de sortie, le second palier et le cylindre de support sont disposés à des positions se chevauchant mutuellement lorsqu'ils sont observés dans une direction radiale. Au moins une partie du dispositif de détection de rotation est disposée à une position faisant face à l'extérieur, dans la direction radiale, du cylindre de support.
(JA) 本発明の電動アクチュエータの一つの態様は、中心軸に沿って延びるモータシャフトを有するモータと、モータシャフトに連結される減速機構と、出力シャフト部を有する出力部と、出力部の回転を検出する回転検出装置と、ケースと、モータシャフトと出力部とを相互に回転可能に連結する第1ベアリングと、ケースに対して出力部を回転可能に支持する第2ベアリングと、を備える。ケースの内面のうち、減速機構の軸方向一方側に位置する部分には、第2ベアリングが嵌合される支持筒部が設けられる。第1ベアリング、出力部、第2ベアリングおよび支持筒部が、径方向から見て互いに重なる位置に配置される。回転検出装置の少なくとも一部が、支持筒部の径方向外側に対向する位置に配置される。
