METHOD FOR PRODUCING A TAPERED ROLLER ASSEMBLY, TAPERED ROLLER ASSEMBLY AND TAPERED ROLLER BEARING

摘要

Tapered roller bearings have in many design forms an inner ring, an outer ring and a plurality of tapered rollers which are arranged to roll between the inner ring and outer ring. It is the object of the present invention to propose a method for producing a tapered roller assembly which can be mounted in a particularly simple manner. For this purpose, a method for producing a tapered roller assembly (1) having an inner ring (3) and a roller ring (12) is proposed, wherein the method comprises the following steps: a) providing the inner ring (3), wherein the inner ring (3) has a flanged mounting rim (10) which is produced within a preliminary flanging stage by flanging over an edge region (6) of the inner ring (3); b) mounting the roller ring (12) on the inner ring (3), wherein the roller ring (12) is pushed over the flanged mounting rim (10) onto the inner ring (3); c) flanging over the flanged mounting rim (10) into a flanged rim (15), wherein the flanged rim (15), as a retaining rim, captively retains the roller ring (12); and d) heat-treating the flanged mounting rim (10) before step b) or step c), wherein a hardness of the flanged mounting rim (10) is reduced by comparison with a hardness of a raceway (5) of the inner ring (3). Also proposed is a tapered roller bearing (20) formed with such a tapered roller assembly (1).
