Title

LINEAR ACTUATOR
(FR)
ACTIONNEUR LINÉAIRE
(JA)
リニアアクチュエータ
Abstract:
(EN)
A linear actuator that can appropriately drive a mobile body, even when a viscoelastic body is provided between the mobile body and a fixed body. A linear actuator 1 that has: a fixed body 2; a mobile body 6; a magnetic drive mechanism 5 that linearly drives the mobile body 6 relative to the fixed body 2; and a viscoelastic body 9 that comprises a silicone gel or the like that is provided between the fixed body 2 and the mobile body 6. The viscoelastic body 9 is provided between fixed-body-side flat parts (a first fixed plate 331, a second fixed plate 332, or the like) and mobile-body-side flat parts (a first side plate part 76, a second side plate part 77, or the like) that pertain to a case 3 of the fixed body 2 and a first yoke 7 of the mobile body 6 and that are parallel and face in a first direction and a second direction Y that are orthogonal to a drive direction Z for the magnetic drive mechanism 5. As a result, when the mobile body 6 is driven, the mobile body 6 undergoes shearing deformation.
(FR)
La présente invention concerne un actionneur linéaire qui peut entraîner de manière appropriée un corps mobile, même lorsqu'un corps viscoélastique est disposé entre le corps mobile et un corps fixe. Un actionneur linéaire (1) comprend : un corps fixe (2) ; un corps mobile (6) ; un mécanisme d'entraînement magnétique (5) qui entraîne linéairement le corps mobile (6) par rapport au corps fixe (2) ; et un corps viscoélastique (9) qui comprend un gel de silicone ou similaire qui est disposé entre le corps fixe (2) et le corps mobile (6). Le corps viscoélastique (9) est disposé entre des parties plates côté corps fixe (une première plaque fixe (331), une deuxième plaque fixe (332) ou similaire) et des parties plates côté corps mobile (une première partie de plaque latérale (76), une deuxième partie de plaque latérale (77) ou similaire) qui appartiennent à un boîtier (3) du corps fixe (2) et à une première fourche (7) du corps mobile (6) et qui sont parallèles et se font face dans une première direction et une deuxième direction Y qui sont orthogonales à une direction d'entraînement Z pour le mécanisme d'entraînement magnétique (5). En conséquence, lorsque le corps mobile (6) est entraîné, le corps mobile (6) subit une déformation de cisaillement.
(JA)
リニアアクチュエータは、可動体と固定体との間に粘弾性体を設けた場合でも、可動体を適正に駆動することができる。たとえば、リニアアクチュエータ1は、固定体2と、可動体6と、固定体2に対して可動体6を直線的に駆動する磁気駆動機構5と、固定体2と可動体6との間に設けられたシリコーンゲル等からなる粘弾性体9とを有している。粘弾性体9は、固定体2のケース3と可動体6の第1ヨーク7とにおいて、磁気駆動機構5による駆動方向Zに対して直交する第1方向および第2方向Yで平行に対向する固定体側平面部(第1固定板331、第2固定板332等)と可動体側平面部(第1側板部76、第2側板部77等)との間に設けられている。従って、可動体6が駆動されたとき、可動体6はせん断変形する。
