METHOD FOR MANUFACTURING ROLLING BEARING UNIT

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 b...

Zusammenfassung:	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 ¸, 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 ¸, and the pitch circle diameter D h is regulated so that the relationship Nh/Nr = cos¸ + (2L/D h ) sin¸ is satisfied.
