Title:
TRIPOD-TYPE CONSTANT-VELOCITY UNIVERSAL JOINT
Document Type and Number:
WIPO Patent Application WO/2019/059204
Kind Code:
A1
Abstract:
In the present invention, an outer peripheral surface of an outside roller of a roller mechanism comprises an outward side surface and an inward side surface, which are disposed asymmetrically relative to a plane that is orthogonal to an axis line of the outside roller and that passes through a center point of the outside roller. A roller guide surface of a track groove comprises an outward guide surface for guiding the outward side surface, and an inward guide surface for guiding the inward side surface. Either the outward guide surface or the inward guide surface is made to be a concave curved surface forming line contact with an outside roller-side convex curve surface, and the other guide surface is made to be a convex curve surface forming line contact with an outside roller-side conical surface.
