摘要：
A tripod constant velocity universal joint is configured with only three parts including an outer ring (10), a tripod (20), and spherical rollers (30). Trunnions (26) are allowed to make direct contact with the spherical rollers (30). The outer ring (10) includes three track grooves (14) parallel to its axis in the inner circumference thereof. Roller guide surfaces (16) are formed on both side walls of the respective track grooves (14). The tripod (20) is inserted inside the outer ring (10) and composed of a boss (22) and three trunnions (26) protruding radially from the boss (22). The spherical rollers (30) are rotatably supported on the trunnions (26), and can move in the axial direction of the outer ring (10) as they roll in the track grooves (14) of the outer ring (10) along the roller guide surfaces (16).
