Split yoke universal joint

摘要

A universal joint has a cross formed by two mutually perpendicular pairs of coaxial trunnions, each pair of trunnions being rotatably received in bearings which in turn are coaxially retained in the bearing caps of one of two yokes. The yokes are subdivided into half sections which each include one of the bearing caps. The half sections of each yoke are separably interconnected with a juncture therebetween defined by confronting mating surfaces. Interengaging elements are provided at the juncture for preventing the thus interconnected half sections from shifting in relation to each other in directions which disturb the coaxial alignment of the bearings.
