  • Patent number: 6162126
    Abstract: A universal joint for interconnecting a pair of rotating shafts and a method of assembling the universal joint. The universal joint includes a pair of yokes secured to the shafts and a cruciform for interconnecting the yokes. Both yokes are bifurcated to define a pair of laterally-spaced legs. Each leg has an aperture which includes a first bore adapted to receive a bearing cup therein and a second bore into which an end portion of the bearing cup extends. Each bearing cup rotatably supports one of four orthogonal trunions extending from the cruciform. With respect to each of the yokes, a pair of axially-aligned trunions, with bearing cups mounted thereon, are installed into the apertures so as to support the cruciform between the legs of the yoke. Thereafter, a retention member is inserted in the second bore of each aperture such that one surface of the retention member rests on the bearing cup.
