Non-standard deep groove ball high-temperature bearing

Abstract

The invention relates to a non-standard deep groove ball high-temperature bearing which comprises an outer ring, an inner ring, a steel ball and half-retainers, wherein the steel ball is arranged between the inner ring and the outer ring; the two half-retainers are riveted together by using rivets, the steel ball is arranged in a pocket hole of the two half-retainers, and the radius of curvature of the outer surface of the outer ring is R500mm. The radius of curvature of the outer surface of the outer ring of the bearing is R500mm, thus the non-standard deep groove ball high-temperature bearing has the advantages of small contact area, lightened abrasion to rails, reduced noise, capability of preventing stress concentration, and prolonged service life. Compared with the traditional bearing, the non-standard deep groove ball high-temperature bearing has service life of being prolonged by one time and rail abrasion loss of being reduced by 40 percent, and is mainly used for two-way stretch horizontal-zipper clamp bearings.

Description

technical field [0001] The invention relates to a bearing, in particular to a non-standard deep groove ball high temperature bearing. Background technique [0002] Deep groove ball bearings are simple in structure and easy to use and maintain. It is mainly used to bear radial load, and can also bear certain axial load. When the radial clearance of the bearing increases, it has the performance of angular contact ball bearing and can bear large axial load. This type of bearing has large frictional resistance and high limit speed, and is suitable for high-speed operation. Therefore, it is often used as a two-way tensile horizontal zipper clip bearing and used on a track. However, the traditional zipper clip bearings (including imported bearings) have shortcomings in design. The outer surface of the bearing outer ring is a cylindrical surface, and the stress is concentrated during use. When running at high speed on the track, the track is severely worn. Especially in the corn...

AI Technical Summary

Problems solved by technology

However, the traditional zipper clip bearings (including imported bearings) have shortcomings in design. The outer surface of the bearing outer ring is a cylindrical surface, and the stress is concentrated during use. When running at high speed on the track, the track is severely worn. Especially in the corners, the wear on the track is more serious, thus greatly shortening the service life of the bearing
