  • Patent number: 4637807
    Abstract: 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.

  • Patent number: 4575361
    Abstract: A cast or forged universal joint yoke having a hub from which extend a pair of arms in spaced apart parallel relation. Each arm as a generally U-shaped bearing cup receiving recess, each recess including a pair of arcuate bearing cup surfaces along the sides thereof. A depression is located in the bight portion of the recess and an integral bearing cup positioning and retaining lug protrudes from the depression. The depression extends on each side of the lug between the lug and adjacent support surfaces so that there is no radius or transition of material between the lug and the supporting surfaces.
