Bearing assembly

Abstract

The invention relates to a bearing assembly comprising two rolling-element bearings, each including an inner ring and an outer ring as well as rolling elements disposed between the bearing rings, wherein the two rolling-element bearings can be preloaded in the axial direction by relative displacement of the inner rings and/or the outer rings, wherein flanges are disposed on the inner rings and/or on the outer rings, which flanges form an axial stop for the rolling elements, and wherein at least one flange is disposed on the bearing ring such that it is adjustable in the axial direction relative to the bearing ring carrying it. In order to perform the preloading in the bearing assembly in a precise manner and ensure that sufficient space is available for the required components, the invention provides a flange displaceable relative to the bearing ring-configured as a flange ring-includes a first section that is displaceable on the bearing ring with a sliding seat and that the flange includes a second section, axially adjacent to the first section, that comprises a thread, wherein the thread can be brought into engagement with a counterthread that is incorporated in a separate component, wherein the separate component is disposed axially spaced with respect to the bearing ring.

Description

technical field [0001] The invention relates to a bearing combination unit, which comprises two sets of rolling bearings, each set of rolling bearings has an inner ring, an outer ring and rolling elements arranged between the bearing rings, wherein the two sets of rolling bearings can pass through the inner ring and / or the outer ring. The relative movement of the rings in the axial direction is preloaded (vorgespannt), and the inner and / or outer rings are provided with ribs (Borde), which form axial stops (Anschlag) for the rolling elements, and the ribs At least one of the ribs is axially adjustably arranged on the bearing ring relative to the bearing ring for carrying it. Background technique [0002] A bearing combination unit of this type is known from DE 10 2012 221 297 A1. With this known solution it is possible to axially preload two interacting roller bearings, in particular tapered roller bearings, against each other. In this case, the adjustment of the preload is...

Problems solved by technology

[0003] The known solutions are not perfect in that there is only little installation space available for adjusting the bearing preload or the corresponding bearing play (Lagespiel), which makes it relatively difficult to install and adjust the necessary components
