Title:

METHOD FOR MANUFACTURING ROLLING BEARING UNIT

Document Type and Number:

WIPO Patent Application WO/2016/013668

Kind Code:

A1

Abstract:

　To realize a structure capable of preventing radial streaks from being formed on the tooth end surface of individual teeth constituting a hub-side face spline (21). When L represents the swing center distance, θ represents the swing angle, which is the tilt angle of the center axis of a roller (30) relative to the center axis of a hub body (8), Dh represents the pitch circle diameter of the hub-side face spline (21), Nh represents the number of teeth on the hub-side face spline (21), and Nr represents the number of teeth formed on the work surface (31) of the roller (30), the positional relationship between the hub body (8) and the roller (30), i.e., at least one of the swing center distance L, the swing angle θ, and the pitch circle diameter Dh of the hub-side face spline is restricted so as to satisfy the relationship Nr/Nh=cos θ + (2L/Dh)•sin θ.
