Friction reduction bearing and preparation method thereof

Abstract

The invention discloses a friction reduction bearing and a preparation method thereof, and relates to the technology field of bearings. The friction reduction bearing structurally comprises a base body and a solid lubricant; the base body is hollow cylinder which is formed by a plate in a coiled mode; a blind hole is radially formed in the inner wall of the base body; the solid lubricant is arranged in the blind hole; and the area of the bottom of the blind hole is larger than that of the open part of the blind hole. The blind hole is formed in one side of the plate for the base body, then thesolid lubricant is arranged in the blind hole, thus the side, with the blind hole, of the plate is coiled into the inner wall of the bearing, and the lubricant is fixed through deformation of the plate of the base body; during coiling, a material of the inner wall deforms, the open part of the blind hole is extruded, and thus the area of the open part is smaller than the area before deformation;and a material of the outer wall is stretched, the bottom of the blind hole is also stretched, thus the area of the bottom of the blind hole is larger than that of the open part of the blind hole, thelubricant is firmly fixed in the blind hole, and the bearing performance is more stable.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an antifriction bearing and a preparation method thereof. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Therefore, the bearing needs to have good tribological properties and strength to meet the working conditions. [0003] Inlaid bearing is a kind of antifriction bearing, the purpose is to improve the tribological performance of the bearing. Inlaid bearings are inlaid with solid lubricants on the metal substrate, which breaks through the limitations of ordinary bearings relying on oil film lubrication. During use, the solid lubricant rubs against the shaft through frictional heat, the metal matrix mainly meets the strength requirements, and the solid lubricant makes the bearing...

AI Technical Summary

Problems solved by technology

If the bonding method is used, frictional heat will be generated during the working process of the bearing, which may cause the adhesive to fail, and the bonding force will not be strong, which will affect the performance. If the parts are disassembled, the solid lubricant will fall off and it is not suitable for assembly; With over-win press-in, the solid lubricant tends to be pulled out, and there is stress, which will also affect the performance
