ABSTRACT:
A tripod type constant velocity universal joint comprises a driven part having an axis of rotation; a driving part having an axis of rotation; a spider member, integral with one of the parts, having three roller supporting rods extended radially from the concentrated portion thereof with an angle of 120 degrees formed therebetween; three roller elements respectively rotatably supported on the roller supporting rods and slidable along the axial directions of the roller supporting rods; and a pot member, integral with the other of the parts, defining three pairs of roller raceways. The longitudinal axis of each pair of roller raceways symmetrically approaches along straight lines a rotational axis of the pot member on both sides of the roller raceways in their longitudinal direction. The tripod type constant velocity universal joint of the present invention decreases the quantities of nonconstant rotational velocity by decreasing the difference of the pitch radiuses of the portions at which two adjacent roller elements are respectively located between the pairs of roller raceways, and reduces the size and weight thereof.
