    摘要: Provided are a face spline forming apparatus and a face spline forming method, with which fluctuation of an inner diameter of a cup section can be suppressed and a face spline can be formed stably. An outer joint member formed by the face spline forming apparatus and the face spline forming method, and a constant velocity universal joint using the outer joint member thus formed are proposed. The face spline forming apparatus comprises: a punch member (50) having a tooth portion (62) for forming a face spline (28); a pedestal (53) having an end-surface receiving surface (52) for receiving an opening end surface (51) of a cup section (7); and a shaft member (57) having an inner-surface receiving surface (56) for receiving a bottom-wall inner surface (55) of the cup section (7). The opening end surface (51) and the bottom-wall inner surface (52) are brought into a simultaneous pressure receiving state. In this state, the punch member performs rocking motion to form the face spline (28) in a bottom-wall back surface (26a) due to plastic deformation caused by the tooth portion (62) of the punch member (50).

    摘要: There is provided a method capable of producing a wheel-supporting rolling bearing unit at low cost. In an event of producing a wheel-supporting rolling bearing unit (1), a cylindrical portion (11) formed in an axial end portion of a hub ring (2) is inserted through an inner ring (3), swing caulking is performed by pressing a die (23) against a tip end portion of the cylindrical portion (11) protruding to an axial end portion side more than the inner ring (3), and an axial end surface (3a) of the inner ring (3) is held by a caulked portion (12) formed by caulking and expanding the tip end portion of the cylindrical portion (11) radially outward. In such a way, the inner ring (3) and the hub ring (2) are fixed integrally witch each other. At this time, a swing angle of the swing caulking is set at 15 degrees or more to 30 degrees or less.
