    摘要： A method for manufacturing a rolling bearing unit is provided to periodically reciprocate a stage (38) in a vertical direction by rotating and driving a servo motor (44) while rotating a roll about a central axis of a hub main body using a roll driving motor (43) in a state in which a processing surface of the roll is pressed against other end surface of a caulking section in an axial direction. A period of the reciprocation is restricted by a relation between a rotation position of the roll about the central axis of the hub main body and an engaged state between concave sections, which are sections between a plurality of processed teeth formed in the processing surface of the roll, and a face spline tooth formed by the concave section.

    摘要： Construction is achieved that is capable of preventing the formation of radial streaks in the tip-end surfaces of teeth of hub-side face splines 21. When a swing center distance is taken to be L, a swing angle that is the inclination angle of the center axis of a roll 30 with respect to a main hub body 8 is taken to be θ, the pitch diameter of the hub-side face splines 21 is taken to be D h , the number of teeth of the hub-side face splines 21 is taken to be N h , and the number of teeth of a processing surface 31 of the roll 30 is taken to be N r , the position relationship of the main hub body 8 and the roll 30, or in other words, at least one of the swing center distance L, the swing angle θ, and the pitch circle diameter D h is regulated so that the relationship Nh/Nr = cosθ + (2L/D h ) ● sinθ is satisfied.

    摘要： There is provided a method for forming a concave constituting a ball return passage directly on an inner circumferential surface of a nut blank by plastic working without damaging a die, even in a case where a nut having a long axial dimension and a small diameter is manufactured. Letter S shaped concaves (15, 16) are formed on an inner circumferential surface (11) of a nut blank (1), by a pressing method by use of a die having a blank holder (2), a cam driver (6), cam sliders (7, 8), and a cylindrical member (5). The cam driver (6) has inclined surfaces (61b, 61d) having the same angle of inclination with inclined surfaces (71, 81) of cam sliders (7, 8). The cam sliders (7, 8) have letter S shaped convexes (73, 83) corresponding to the letter S shaped concaves (15, 16), ad are held by through holes (52, 53), respectively. When the cam driver (6) is pressed under pressure from the top thereof, the cam sliders (7, 8) move outwardly in the radial direction, respectively, and the letter S shaped convexes (73, 83) push the inner circumferential surface (11) of the nut blank (1) for plastic deformation.
