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

摘要

A method is disclosed 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 having an inner ring and a roller ring is proposed, wherein the method comprises the following steps: a) providing the inner ring , wherein the inner ring has a flanged mounting rim which is produced within a preliminary flanging stage by flanging over an edge region of the inner ring; b) mounting the roller ring on the inner ring, wherein the roller ring is pushed over the flanged mounting rim onto the inner ring; c) flanging over the flanged mounting rim into a flanged rim wherein the flanged rim, as a retaining rim, captively retains the roller ring; and d) heat treating the flanged mounting rim before step b) or step c), wherein a hardness of the flanged mounting rim is reduced by comparison with a hardness of a raceway of the inner ring. Also proposed is a tapered roller bearing formed with such a tapered roller assembly.
