ABSTRACT:
In a tripod type constant velocity joint a tripod is disposed within a cylindrical housing such that three equi-angularly spaced trunnions of the tripod are received within corresponding recesses of the housing. Each trunnion has a spherical roller mounted thereon through a plurality of rolling bearing members, and a cylindrical roller mounted on the spherical roller. An inner peripheral concave spherical surface of the cylindrical roller is in intimate sliding contact with an outer peripheral convex spherical surface of the spherical roller, and an outer cylindrical surface of the cylindrical roller is in rolling contact with the opposite side surfaces of the corresponding recess. The rolling bearing members, the spherical rollers, and the cylindrical rollers are disposed within a circle formed by linking the ends of the trunnions together.
