Fixed constant velocity universal joint, method of manufacturing fixed constant velocity universal joint, and bearing device adapted for use in driving wheel and using fixed constant velocity universal joint
Abstract:
A fixed type constant velocity universal joint includes an outer joint member, an inner joint member, a plurality of balls interposed between the outer and inner joint members, and a cage to hold the plurality of balls. At least one of the plurality of track grooves of the outer joint member and the plurality of track grooves of the inner joint member is formed by cold-forging finishing. The outer joint member, the inner joint member, the balls, and the cage are assembled to each other based on matching in which the plurality of balls and the cage each having a rank corresponding to a measured value of a pitch circle diameter of the outer joint member and to a measured value of a pitch circle diameter of the inner joint member, which have been arbitrarily selected, are selected with respect to the arbitrarily selected outer and inner joint members.
