Title:
HIGH-FREQUENCY HEAT TREATMENT COIL, OUTER-SIDE JOINT MEMBER FOR CONSTANT-VELOCITY UNIVERSAL JOINT, AND CONSTANT-VELOCITY UNIVERSAL JOINT
Document Type and Number:
WIPO Patent Application WO/2013/065818
Kind Code:
A1
Abstract:
Provided are: a high-frequency heat treatment coil that can be assembled with high dimension-precision and to which high-quality heat treatment can be applied; a method of manufacturing such a high-frequency heat treatment coil; a constant-velocity universal joint to which high-quality heat treatment is applied; and a drive shaft and a propeller shaft using such a constant-velocity universal joint. The method of manufacturing a high-frequency heat treatment coil provided with heating sections (71a, 71b, 71c) for heating portions of an outer-side joint member (51) for the constant-velocity universal joint that are to be subjected to heating, wherein the heating sections (71a, 71b, 71c) are formed by machining in an integrated manner, and the high-frequency heat treatment coil is completed by joining these heating sections (71a, 71b, 71c) with the other sections.
