Title
(EN) VIBRATION REDUCER WITH FLEXURES
(FR) RÉDUCTEUR DE VIBRATION À FLEXIONS
Abstract
(EN) A vibration reducer (6) for reducing a magnitude of a vibration being transferred from a first component (2) to a second component (2) includes (i) a first housing (12); (ii) a second housing (14) positioned within the first housing (12); (iii) a movable member (16); and (iv) a first flexure assembly (18). The movable member (16) includes a movable member head (40), and a movable member shaft (42) that is extends away from the movable member head (40). The first flexure assembly (18) flexibly couples and seals one of (i) the second housing (14) to the first housing (12), and (ii) the movable member (16) and the second housing (14). Further, the first flexure assembly (18) has a low stiffness along a first axis, and a high stiffness along a second axis that is orthogonal to the first axis.
(FR) L'invention concerne un réducteur de vibration (6) destiné à réduire une amplitude d'une vibration qui est transférée d'un premier composant (2) à un second composant (2), comprenant (i) un premier boîtier (12); (ii) un second boîtier (14) positionné à l'intérieur du premier boîtier (12); (iii) un élément mobile (16); et (iv) un premier ensemble à flexion (18). L'élément mobile (16) comprend une tête d'élément mobile (40) et un arbre d'élément mobile (42) qui s'étend à l'opposé de la tête d'élément mobile (40). Le premier ensemble à flexion (18) accouple et scelle de manière flexible soit (i) le second boîtier (14) au premier boîtier (12) soit (ii) l'élément mobile (16) et le second boîtier (14). En outre, le premier ensemble à flexion (18) a une faible rigidité le long d'un premier axe, et a une rigidité élevée le long d'un second axe qui est orthogonal au premier axe.
