Abstract
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) which a common shaft (313), a composite joint (300) can be formed.
