Outer joint member for fixed constant velocity universal joint
摘要:
An outer joint member for a fixed type constant velocity universal joint contributes to the reduction of the number of man-hours through the reduction of the number of processes after a forging process, to an increase in yield, and to the reduction of manufacturing cost. The outer joint member is made of machine-structural carbon steel. The portions of the outer joint member that are finished by cold forging are track grooves, radially inner spherical-surface portions, a cup-inlet chamfer, track chamfers, track-inlet chamfers, a part except for a boot fixing portion on a radially outer surface of the cup section, and a center hole at an end surface of the shaft section.
