Patent ID: 10837498

Abstract:
In a fixed type constant velocity universal joint according to the present invention, six torque transmitting ball tracks (20) are defined as a first track, a second track, a third track, a fourth track, a fifth track, and a sixth track along a circumferential direction. Further, in the fixed type constant velocity universal joint according to the present invention, an axial offset amount of a curvature center of each of track grooves (12) of an outer joint member (13) and an axial offset amount of a curvature center of each of track grooves (15) of an inner joint member (16) are set to 0. Further, in the fixed type constant velocity universal joint according to the present invention, the track grooves (12) of the outer joint member (13) and the track grooves (15) of the inner joint member (16) are each inclined with respect to an axis line.
