Title
(EN) UNIVERSAL JOINT HAVING HEMISPHERICAL CUP-SHAPED YOKE AND EXTERIOR, LUBRICATING RING
(FR) JOINT ARTICULE A JOUG DE FORME EVASEE HEMISPHERIQUE ET ANNEAU EXTERIEUR DE LUBRIFICATION
Abstract
(EN)
A universal joint (310) includes a substantially hemispherical cup-shaped yoke (311) in which is disposed a cross trunnion (312) and which is disposed in a ring (315). Pins (321, 322) connect the ring to the cross trunnion and to the yoke. Lubricant in an annular channel (319) in the ring provides lubrication for the pins (321, 322), whose ends disposed in the ring (315) are surrounded by needle bearings (31). A first shaft (340) is integrally connected to the cross trunnion (312), and a second shaft (513) is integrally connected to the yoke (311). By joining the yokes (311) of two such joints (310) with a common shaft (313), a composite joint (300) can be formed.
(FR)
Un joint articulé (310) comprend un joug de forme évasée hémisphérique (311) dans lequel est disposé un tourillon transversal (312), lequel est disposé dans un anneau (315). Des tiges (321, 322) relient l'anneau au tourillon transversal ainsi qu'au joug. Un lubrifiant se trouvant dans un canal annulaire (319) situé dans l'anneau assure la lubrification desdites tiges (321, 322) dont les extrémités sont disposées dans ledit anneau (315) et sont entourées par des roulements à aiguilles (31). Un premier arbre (340) est relié de manière solidaire au tourillon transversal (312) et un second arbre (513) est relié de manière solidaire audit joug (311). Le fait d'unir les jougs (311) de deux joints de ce type (310) à l'aide d'un arbre commun (313) permet de former un joint composite (300).
