Bearing assembly

Abstract

A bearing assembly (1) is disclsoed in the invention and includes at least one rolling-element bearing (2) that includes a bearing outer ring (6) and a bearing inner ring (4) and rolling elements (8)disposed therebetween. The at least one rolling-element bearing is mounted in a component with the bearing outer ring in contact with the component, and the outer bearing ring includes a first edge surface extending between a rolling-element raceway and a radial end surface of bearing ring, and / or a second edge surface extending between an axial outer fitting surface and the radial end surface ofthe bearing ring. The component includes, on a surface facing the first and / or second edge surface, at least one material accumulation (24) that interacts with the first and / or second edge surface.

Description

technical field [0001] The present invention relates to a bearing assembly according to the preamble of technical solution 1 of this patent. Background technique [0002] The bearing assembly comprises at least one rolling bearing, in particular a tapered roller bearing, comprising a bearing outer ring and a bearing inner ring between which rolling elements are arranged, and a seat for receiving the bearing outer ring. For reasons of strength and weight, the component parts of the bearing, such as the bearing rings, usually consist of steel, while light metals, especially aluminum, are used for the housing. Here, the bearing cup can be mounted in the seat by friction fit (for example using a press fit) such that a rotationally fixed fixation is achieved between the bearing cup and the seat (with an overlap provided between the bearing cup and the seat). [0003] However, there is the following problem with such bearing assemblies: the seat made of light metal has a greater ...

Problems solved by technology

[0003] However, there is the following problem with such bearing assemblies: the seat made of light metal has a greater thermal expansion than the component parts of the bearing, as a result, during operation and with the resulting temperature rise, Transition from a press fit to a loose fit between the bearing outer ring and seat, whereby the anti-rotational fixation between the bearing outer ring and seat is no longer ensured

However, the disadvantage here is that for this purpose the element has to be specially prefabricated in order to fit it into the groove, with the result that the manufacture in turn becomes complicated and expensive
