Title:
OUTSIDE JOINT MEMBER OF CONSTANT VELOCITY UNIVERSAL JOINT
Document Type and Number:
Japanese Patent JP2015052364
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an outside joint member of a constant velocity universal joint, which is light and compact, inexpensive to manufacture, and good in accuracy.SOLUTION: Outside joint members (2, 22, 42, 62) of constant velocity universal joints (1, 21, 41, 61) include two members, namely, cup members (15', 35', 55', 75') forming cup parts (15, 35, 55, 75) and shaft members (16', 36', 56', 76') forming shaft parts (16, 36, 56, 76), which are welded to each other, respectively. The cup members (15', 35', 55', 75') are formed of steel plates, where depth side ends (15a, 35a, 55a, 75a) of track grooves (7, 27, 46, 67) are diameter-shrunk in curved shapes and pressed into such shapes as to be connected to circular parts (15b, 35b, 55b, 75b), respectively. In the thickness cross section of the steel plates, the circular parts (15b, 35b, 55b, 75b) are welded to the shaft members (16', 36', 56', 76'), respectively.
