ABSTRACT:
A stroking constant velocity universal joint including a tulip housing having three longitudinal drive channels therein and a spider having three radial trunnions reaching into the drive channels. A cylindrical drive roller is disposed in each drive channel and has a radial bore therein with an inner convex surface around a cylindrical bearing race on the corresponding radial trunnion. A full complement of needle bearings is disposed in the clearance between each cylindrical bearing race and the corresponding inner convex surface. A pair of annular washers are mounted on each radial trunnion at opposite ends of the bearing race thereon. A counterbore in a side of each washer facing the corresponding drive roller has a diameter less than the minimum diameter of the inner convex surface in the drive roller and overlaps an end of the full complement of needle bearings to hold the needle bearings closer to the cylindrical bearing race than the inner convex surface of the drive roller.
