Title
(EN) CENTER BEARING
(FR) PALIER CENTRAL
(JA) センターベアリング
Abstract
(EN)
Provided is a center bearing with reduced vibration and increased durability. A center bearing (2) is provided with a bracket (12), a radial bearing (9), a pair of bellows (13), and a stopper (14). The bellows (13) each have a diaphragm section (19), the center of which in a radial direction bulges outward in an axial direction. The stopper (14) is directly or indirectly affixed to the radial bearing or the bracket and is formed so as to protrude in the radial direction. The stopper (14) has formed thereon a flange section (24) extending to one side or both sides in the axial direction.
(FR)
L'invention concerne un palier central caractérisé par des vibrations réduites et une durabilité accrue. Un palier central (2) est muni d'un support (12), d'un palier radial (9), d'une paire de soufflets (13), et d'un arrêtoir (14). Les soufflets (13) comprennent chacun une section (19) de diaphragme, dont le centre dans une direction radiale est renflé vers l'extérieur dans une direction axiale. L'arrêtoir (14) est fixé directement ou indirectement au palier radial ou au support et est formé de façon à faire saillie dans la direction radiale. Sur l'arrêtoir (14) est formée une section (24) de bride s'étendant d'un côté ou des deux côtés dans la direction axiale.
