Angular contact bearing pre-tightening method

Abstract

The invention relates to the technical field of bearing pre-tightening, in particular to an angular contact bearing pre-tightening method. The method comprises the following steps that the length of a bearing inner ring mounting position is measured; the left side end of an angular contact bearing is provided with a first measuring block, and the right side end of the angular contact bearing is provided with a second measuring block; the thickness of the first measuring block and the thickness of the second measuring block are measured through a measuring instrument; the first measuring block and the second measuring block are installed in a mounting bearing outer ring part main body, so that the mounting end face is tightly attached to the main body mounting bearing end face; the high-precision measuring instrument is used for measuring the distance between the opposite end faces of the first measuring block and the second measuring block, the distance between the outer side end face of the first measuring block and the left side end face of the main body as well as the distance between the outer side end face of the second measuring block and the right side end face of the main body; the distance L between the two end faces of the mounting bearing outer ring part main body is calculated; and the thickness of a gasket is calculated through the value L. By adoption of the method, the accurate size of the angular contact bearing adjusting gasket is obtained by arranging the measuring blocks, and it is guaranteed that the pre-tightening force of the angular contact bearing is achieved.

Description

Technical field[0001]The present invention relates to the field of bearing pretensioning techniques, and the specific field is a angular contact bearing Tighting method.Background technique[0002]The angular contact bearing pretension is achieved by the precision relative movement between the angular contact bearing, and one of the mounting methods is to develop the adjusted gasket, but after the two end angle contact bearing is installed, there is always an axial error due to the installation And the end surface distance between the part of the part of the angular contact bearing outer ring is unable to measure, which makes the adjustment of the size of the gasket less accurate data, thereby affecting the implementation of the angular contact bearing pretty, affects angular contact bearing Use performance.Inventive content[0003]Aiming to the prior art, it is an object of the present invention to provide a angular contact bearing pre-tight method.[0004]In order to achieve the above o...

Problems solved by technology

[0002] The preload of angular contact bearings is achieved through the precise relative movement between the inner and outer rings of the angular contact bearings. One of the installation methods is to grind and adjust the washers. However, after the angular contact bearings at both ends are installed, there are often axial errors due to installation. , and the distance between the two ends of the inner hole of the part installed with the outer ring of the angular contact bearing cannot be directly measured, which makes it impossible to obtain accurate data on the size of the adjusting washer, which affects the realization of the preload of the angular contact bearing and affects the angular contact bearing. performance
