ABSTRACT:
A constant velocity universal joint has an outer female or track part having three grooves within it running in its axial direction. Within the female part the trunnion part is placed which is designed with three rollers which, like the grooves, are equally spaced in angle about the joint's axis, and they are keyingly taken up in the grooves. The rollers are generally mushroom-like and their heads are designed for making rolling contact against sides of the grooves, while their radial stems take the form of turnpins for turningly supporting the rollers in the male joint half. The outer faces of the mushroom-like rollers are spherical and centered on the middle of the joint when the joint halves are in the in-line position. The radially inner ends of the rollers are flat and between them a ball or cylindrical body is placed for positively keeping the outer spherical faces of the rollers against narrow lands (running in the axial direction of the joint) on the floors of the three grooves.
