Title
(EN) SEAL CASE WITH OVER-MOLDED RUBBER GASKET SECURING PLASTIC WAFER
(FR) BOÎTIER DE JOINT D'ÉTANCHÉITÉ AYANT UN JOINT EN CAOUTCHOUC SURMOULÉ FIXANT UNE PLAQUETTE EN PLASTIQUE
Abstract
(EN)
A seal case for a bearing seal includes (a) an inner case encircling a rotation axis of the bearing seal, (b) an outer case encircling the rotation axis and including a ring-shaped frame and a rubber gasket over-molded on the frame, and (c) a plastic wafer clamped between the inner case and the outer case, and secured at least by the rubber gasket. A method for manufacturing a bearing seal includes over-molding a rubber gasket onto a ring- shaped frame to form an outer case, placing a plastic wafer between the rubber gasket and an inner case, and securing the inner case to the outer case to form a seal case.
(FR)
La présente invention concerne un boîtier de joint d'étanchéité pour un joint d'étanchéité de palier, ledit boîtier de joint d'étanchéité comprenant (a) un boîtier interne encerclant un axe de rotation du joint d'étanchéité de palier, (b) un boîtier externe encerclant l'axe de rotation et comprenant un cadre en forme d'anneau et un joint en caoutchouc surmoulé sur le cadre, et (c) une plaquette en plastique serrée entre le boîtier interne et le boîtier externe et fixée au moins par le joint en caoutchouc. Un procédé de fabrication d'un joint d'étanchéité de palier consiste à surmouler un joint en caoutchouc sur un cadre en forme d'anneau pour former un boîtier externe, à placer une plaquette en plastique entre le joint en caoutchouc et un boîtier intérieur et à fixer le boîtier interne au boîtier externe pour former un boîtier de joint d'étanchéité.
