Bearing inner ring for taper roller bearing, has ring board including board side, and outer stating section whose curvature radius is larger than board height of ring board over taper roller bearing running surface i.e. taper stump surface

摘要

The ring has a ring board (2) including a board side (3) that faces toward a taper roller bearing running surface (1) that is formed as a taper stump surface. The ring board is designed in such a manner that the board side includes a rectilinear inner stating section (P) in an axial section plane that consists of a bearing axis and a convex curved outer stating section (C) in a transition zone (T). Curvature radius (R) of the outer stating section is larger than board height (H) of the ring board over the taper roller bearing running surface.
