Title:
STATIONARY CONSTANT-VELOCITY UNIVERSAL JOINT
Document Type and Number:
WIPO Patent Application WO/2017/141731
Kind Code:
A1
Abstract:
In the present invention, the axial-direction offset between the center of curvature of track grooves of an outer joint member and the center of curvature of track grooves of an inner joint member is zero. The track grooves of the outer joint members and the track grooves of the inner joint member are each inclined with respect to the axial line. The directions of inclination of track grooves that are adjacent in the circumferential direction are opposite. Track grooves of the outer joint member are inclined in the opposite directions from the directions of inclination of facing track grooves of the inner joint member. A chamfered section is formed on the track entry end of each track groove of the outer joint member. A cage and the inner joint member are inclined with respect to the outer joint member, making it possible to incorporate balls simultaneously in the track entry ends to two cage windows via the chamfered section.
