Axial and radial combined deep groove ball thrust ball bearing

Abstract

The invention discloses an axial and radial combined deep groove ball thrust ball bearing which comprises a radial bearing assembly and an axial bearing assembly; the radial bearing assembly comprises an outer ring, an inner ring and a radial bearing steel ball mounted between the outer ring and the inner ring in a rolling manner; the radial bearing steel ball is mounted on a radial retainer; the axial bearing assembly comprises an inner ring, a race and an axial steel ball group connected between the inner ring and the race in a rolling manner; and the axial steel ball group is mounted on an axial retainer. The axial bearing force of the axial and radial combined deep groove ball thrust ball bearing is greatly increased; the axial and radial combined deep groove ball thrust ball bearing can bear higher revolving speed, saves the mounting space, is convenient to mount, reduces the mounting spoilage, and prolongs the service life; the inner ring of the radial bearing assembly serves as a blowout patch of the axial bearing assembly, so that the space is saved, the cost is reduced, and the service life is prolonged; and the axial and radial combined deep groove ball thrust ball bearing is compact in structure and more stable in operation, improves the coaxiality, can bear higher revolving speed, and lowers the noise.

Description

technical field [0001] The invention belongs to the field of bearing structures, and in particular relates to a radial and axial composite deep groove ball thrust ball bearing capable of simultaneously bearing combined radial and axial loads, which is mainly used in the fields of gearboxes, machine tool spindles and the like. Background technique [0002] A bearing is a component used in a rotating mechanism to support, reduce friction and bear loads. This product is mainly designed for gearboxes and other machinery. Because it can bear radial load and axial load at the same time, especially in the occasions where the speed is high and there is a large axial load, it is easy to assemble and disassemble and has a strong bearing capacity. And the installation location is small. Therefore, it is suitable for gearboxes, spindles and other machinery with radial loads and large axial loads. At present, NUP plus deep groove balls are mainly used in China to meet the requirements ...

AI Technical Summary

Problems solved by technology

At present, NUP and deep groove balls are mainly used in China to meet the requirements of working conditions, but the axial load is difficult to meet the requirements, and the installation space is relatively large, and the machining accuracy of the casing and shaft is high.
