  • Slidable-type homokinetic (universal) tripod joint
    Patent number: 4773890
    Abstract: A slidable-type homokinetic tripod joint includes an outer member formed with track grooves, a tripod member having three trunnions and mounted in the outer member with the trunnions on the tripod member received in the track grooves in the outer member, and a spherical roller rotatably mounted on each trunnion. Each track groove is formed at each side with a guide surface for the spherical roller. The spherical roller is kept in contact with the roller guide surface at two points. This decreases unbalanced load and the turning moment acting on the spherical roller and decreases the friction force causing vibration.
