Embodiment Construction

[0038] In the following, identical or functionally equivalent elements are denoted by the same reference numerals.

[0039] figure 1 The bearing assembly 1 is shown in a first processing step. Here, the bearing assembly comprises a first rolling bearing and a second rolling bearing 2, 4 ( / is constituted by the first rolling bearing and the second rolling bearing 2, 4). The rolling bearings 2 , 4 are designed as double-row bearing assemblies and are arranged axially adjacent to each other. exist figure 1 , a back-to-back arrangement is shown in which the bearing rings are rotatable about the bearing axis A. However, the rolling bearings 2, 4 can also be similarly arranged in a face-to-face arrangement.

[0040] The bearing rings each comprise rolling element races 14 , 16 axially bounded in one direction by guide flanges 6 , 8 . In operation, the rolling elements, in particular the tapered rollers, can roll on the rolling element raceways 14 , 16 . In order not only to g...

Abstract

A bearing assembly (1) is disclosed, comprising a first rolling bearing (2) and a second rolling bearing (4), wherein the first rolling bearing (2) and the second rolling bearing (4) respectively comprise an inner ring and an outer ring , the inner ring and / or the outer ring comprise rolling element raceways (14, 16) axially separated by first flange elements (6, 8) and The second flange element (10, 12) defines, the inner and / or outer rings of the first rolling bearing (2) and the second rolling bearing (4) are arranged axially adjacent to each other, the first rolling bearing (2) Abutting first flange elements (6, 8) or second flange elements (10, 12) of the inner and / or outer ring of the second rolling bearing (4) are configured to be common Flange element (18).

Description

technical field [0001] The present invention relates to a bearing assembly comprising a first rolling bearing and a second rolling bearing, and to a method for manufacturing the bearing assembly. Background technique [0002] Typically, bearing rings for rolling bearings comprise at least one raceway for the rolling elements, which races encircle the bearing axis. The raceway can be defined in the axial direction by flanges, ie guide flanges and retaining flanges, wherein the flanges are used to guide or support the rolling elements. With tapered roller bearings in particular, the guide flanges support the axial forces generated by the rolling elements during operation, while the retaining flanges only perform the holding function of preventing the rolling elements from falling out during transport or assembly. [0003] The flange is usually integral with the bearing ring. However, compared with a flangeless rolling bearing, the production of a bearing ring comprising a fl...
