Title:
CONSTANT-VELOCITY UNIVERSAL JOINT
Document Type and Number:
Japanese Patent JP2018017369
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a constant-velocity universal joint which secures strength of a joint part of a boot while making an operation angle to improve the durability and sealability of the boot.SOLUTION: A constant-velocity universal joint includes: a cup shaped outer joint member 12 having an opening 11; and an inner joint member 13 which transmits torque to the outer joint member 12 through balls 14 while allowing angular displacement. A large diameter end part 24 and a small diameter end part 25 of a boot 23 are respectively joined to an outer peripheral surface of the opening 11 of the outer joint member 12 and an outer peripheral surface of a shaft 17 extending from the inner joint member 13. Ribs 30 are provided on an outer peripheral surface of the large diameter end part 24 of the boot 23, and a joint part 27 is formed between an inner peripheral surface of the large diameter end part 24 of the boot 23 and the outer peripheral surface of the opening 11 of the outer joint member 12 by electromagnetic induction heating.SELECTED DRAWING: Figure 1
