Configuration for a roller of a roller bearing

摘要

A tapered roller for a tapered roller bearing, the tapered roller bearing having a raceway and a flange, and the tapered roller having a rolling surface configured to roll on the raceway and an end surface at the end of the rolling surface configured to face the flange. The end surface includes an abutment surface having a curvature and a radially outer end and a radially inner end and is configured to contact the flange. The curvature increases monotonically from a starting point on the abutment surface to the radially inner end of the abutment surface.

1. A tapered roller for a tapered roller bearing having an end surface that terminates a rolling surface, wherein the tapered rolling element has an abutment surface for contacting a flange of a bearing ring, the curvature of the abutment surface increases monotonically with an increasing of the curvature from a starting point on the abutment surface up to an inner endue of the abutment surface that faces away from the raceway.
