Abstract: front page image
(EN)An improved seal (10) for use in a universal joint (11) having an elastic seal ring (23) compressed between a pair of right circularly cylindrical sleeves (24, 25). The seal ring is bonded to the sleeves. The sleeves are adapted to have press-fitted relationship with association portions of the universal joint, such as the journal trunnion (12) and the bearing retainer (14). In one form, the elongated extent of the sleeves is parallel to the axis (15) of the journal trunnion (12) and in a modified form, the sleeves (124, 125) extend perpendicularly thereto. In each form, a portion of one of the sleeves is disposed adjacent the inner end of the needle bearings (22, 122) so as to limit axial movement thereof. The sleeves are bonded to the seal ring so as to preclude sliding movement therebetween while yet permitting limited axial play in the universal joint thereby to provide long troublefree life of the seal.
(FR)Un joint ameliore (10) utilise dans un joint universel (11) comprend une bague d"etancheite elastique (23) comprimee entre une paire de manchons cylindriques droits (24, 25). La bague d"etancheite est liee aux manchons. Les manchons sont concus pour etre ajustes a force avec des parties associes du joint universel, telles que le tourillon (12) et le dispositif de retenue de palier (14). Dans une forme de realisation, la partie allongee des manchons est parallele a l"axe (15) du tourillon (12) et dans une forme modifiee, les manchons (124, 125) s"etendent perpendiculairement a ce dernier. Dans chaque forme d"execution, une partie de l"un des manchons est disposee de facon adjacente a l"extremite interieure des paliers a aiguilles (22, 122) de maniere a limiter leur mouvement axial. Les manchons sont lies a la bague d"etancheite de maniere a empecher un mouvement de glissement entre eux tout en permettant un jeux axial limite dans le joint universel pour assurer la longevite du joint.
