FIXED CONSTANT VELOCITY UNIVERSAL JOINT

Title:

FIXED CONSTANT VELOCITY UNIVERSAL JOINT

Document Type and Number:

WIPO Patent Application WO/2017/051710

Kind Code:

A1

Abstract:

In this fixed constant velocity universal joint, there are six torque-transmitting ball tracks (20), a first track, second track, third track, fourth track, fifth track and sixth track, along the circumferential direction. Moreover, in this fixed constant velocity universal joint, the offset in the axial direction of both centers of curvature, the centers of curvature of the track grooves (12) of the outer joint member (13) and the centers of curvature of the track grooves (15) of the inner joint member (16), is 0. Furthermore, in this fixed constant velocity universal joint, the track grooves (12) of the outer joint member (13) and the track grooves (15) of the inner joint member (16) are respectively slanted with respect to the axial line. And in this fixed constant velocity universal joint, the track grooves (12) of the outer joint member (13) and the track grooves (15) of the inner joint member (16) that face same are slanted in opposite directions with respect to the axial line, and the angles of inclination of torque-transmitting ball tracks (20) that are adjacent to each other in the circumferential direction differ.
