Title:
CONSTANT VELOCITY UNIVERSAL JOINT
Document Type and Number:
Japanese Patent JP2018189183
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a constant velocity universal joint which prohibits the interference of members, and allows torque transmission and oscillation (slide in an axial direction) in a proper slide range of the constant velocity universal joint, and a power transmission mechanism.SOLUTION: A constant velocity universal joint comprises an axial movement prohibition structure M for prohibiting the axial movement of a shaft S by imparting an elongation force, or a compression force reacting with the compression force or the elongation force to the shaft S in a state that the elongation force or the compression force acts on the shaft S by the own weight of the shaft S, an internal part P and a lubrication member filled into the joint. In a boot 81, a spiral bellows part 81c having an elastic member E is arranged between a pair of opening parts 81a, 81b. The axial movement prohibition structure M is constituted of the spiral bellows part 81c having the elastic member E.SELECTED DRAWING: Figure 2
