ABSTRACT:
A homokinetic tripod type universal joint including a tripod member having three trunnions, with a roller rotatably mounted on each trunnion is mounted in an outer member. The roller consists of an inside ring and an outside ring wherein contact is established between a spherical outer periphery of the inside ring and a cylindrical inner periphery of the outside ring. The outside ring is guided in a direction parallel with the axis of the outer member by guide surfaces provided internally of grooves formed on the outer member. This arrangement helps to reduce sliding resistance, temperature rise and vibrations due to induced thrust.
