INNER JOINT MEMBER FOR CONSTANT VELOCITY UNIVERSAL JOINT, MANUFACTURING METHOD THEREFOR, AND CONSTANT VELOCITY UNIVERSAL JOINT |
摘要 |
Provided is an inner joint member for a constant velocity universal joint, which is capable of extending a life of a cutting tool and achieving reduction in manufacturing cost. The inner joint member for a constant velocity universal joint is incorporated in an outer joint member (3) and has multiple ball track grooves (5) which are formed in an outer diameter surface (4) thereof. A spherical surface roughness in a range extending from an axial center (15) of the outer diameter surface (4) to an end (A) side of the outer diameter surface (4) which corresponds to an opening side of the outer joint member (3) is larger than a spherical surface roughness in a range extending from the axial center (15) of the outer diameter surface (4) to an end (B) side of the outer diameter surface (4) which corresponds to an inner side of the outer joint member (3).
