Problems solved by technology

[0004] However, the mentioned possibilities are either relatively inaccurate or very complex, so there is a need for a method for setting the preload of a bearing assembly of the above type which is not too complex but still delivers sufficiently accurate results

Embodiment Construction

[0029] exist figure 1 In , a bearing assembly 1 is shown, with the use of which a shaft 5 is supported in a housing 6 . For this, two rolling bearings 2 in the form of tapered roller bearings are used which are preloaded against each other, of which only one such as figure 1 shown; another bearing not shown is also a tapered roller bearing and is set in figure 1 on the left side in such that the two bearings are positioned in a back-to-back arrangement. The rolling bearing 2 has a bearing inner ring 3 and a bearing outer ring 4 , between which rolling elements 17 are arranged.

[0030] At the point of contact with the attachment (shaft 5 and housing 6 ), the two bearing rings 3 and 4 comprise electrical insulation 15 or 16 . Current is thus prevented from flowing from the bearing rings 3 , 4 to the attachments 5 , 6 .

[0031] However, on their end sides 9 or 10, the two bearing rings 3, 4 each comprise a non-insulated point 7 or 8, as figure 2 shown. The rolling bearin...

Abstract

The invention relates to a method for adjusting the bias in a bearing assembly (1), wherein the bearing assembly (1) comprises at least one rolling bearing (2) with at least one bearing inner ring (3) and at least one bearing outer ring (4). In order to be able to adjust the bias in an easy way, the adjustment of the bearing bias according to the invention is carried out by the implementation of the following steps: a) increasing the bias in the bearing assembly (1) starting from a lower start value, or decreasing the bias in the bearing assembly (1) starting from an upper start value and simultaneously measuring the electrical resistance (RIst) between the bearing inner ring (3) and the bearing outer ring (4); b) ending the change of the bias in the bearing assembly (1) as soon as a target value (Rsoll) for the electrical resistance is reached. The invention further relates to a bearing assembly comprising a device for adjusting the bias.

Description

technical field [0001] The invention relates to a method for setting a preload in a bearing assembly comprising at least one rolling bearing comprising at least one bearing inner ring and at least one bearing outer ring. Furthermore, the invention relates to a bearing assembly comprising means for setting the preload. Background technique [0002] Preloaded bearing assemblies are well known and common in the art. Usually, two tapered roller bearings (but also angular contact ball bearings, axial roller bearings, axial ball bearings, for example) are clamped against one another in order to support, for example, the shaft in the housing without play. [0003] Here, the setting of the preload in bearing assemblies of the described type, in particular using tapered and angular contact ball bearings, is a laborious and often inaccurate procedure. Here according to the first possibility try to set the correct preload such that the friction torque of the bearing assembly is measu...
