bearing ring

Abstract

The invention relates to a bearing ring (2, 3) for a rolling bearing (1), in particular for a tapered roller bearing, which has a rolling surface (8) for rolling bodies and an essentially axially extending outer surface (10), which is designed to be fixedly connected to the element to be supported in a torsionally fixed manner, and the bearing ring has first and second substantially radially extending axially delimiting the bearing ring (2; 3) Two edge surfaces (12; 14), wherein an edge (16; 18) is formed on at least one edge surface (12; 14), said edge being designed to be flexible under pressure loading. The invention also relates to a rolling element (4) with a flexibly designed end region (20; 22) and a rolling bearing with a bearing ring (2; 3) of this type and/or a rolling bearing (4) of this type.

Description

technical field [0001] The invention relates to a bearing ring for a rolling bearing, in particular for a tapered roller bearing, as well as rolling bodies with linear contact for the rolling bearing, and a rolling bearing with such a bearing ring and / or such rolling bodies. Background technique [0002] For rolling bearings with line contact, in particular tapered roller bearings, in which the rolling elements contact the rolling surface of the bearing ring along a line, the rolling elements lie opposite each other in the case of a non-exactly central and thus oblique position under loading Very high loads, so-called edge stresses, occur at the ends of the It is therefore proposed in the prior art to assign convex profiles to the bearing components, especially the bearing rings and the rolling elements, as a result of which the load can be distributed relatively evenly over the entire rolling elements even in the loaded or inclined position . The convex profile is usually...

AI Technical Summary

Problems solved by technology

The reason for this is, for example, that the wear of the grinding stones and honing sticks used in the manufacturing process to form the profile can lead to ever-increasing deviations from the setpoint

This deviation can even lead to increased edge stress problems

In addition, the machining of bearing components is very expensive

[0004] A further disadvantage of the profiled design is that the rolling elements no longer rest against the rolling surfaces over their entire length due to the profile, which further increases the pressure load on the rolling elements and thus reduces the loadability of the rolling bearing
