ABSTRACT:
A universal joint (310) includes a yoke (311) in which is disposed a dual trunnion (312) and which is disposed in a ring (315). Pins (321, 322) connect the ring to the dual trunnion and to the yoke. Lubricant in a non-continuous lubricant channel (319), extending less than 360.degree. around the ring, provides lubrication for the pins (321, 322), whose ends disposed in the ring (315) are surrounded by needle bearings (31). Because the channel is non-continuous, lubricant entering one lubricant port (320) must travel the length of the lubricant channel before exiting the channel via the second lubricant port (326). In this manner, the lubricant channel is purgable and lubricant is supplied to all bearings. A first shaft (340) is integrally connected to the dual 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.
