A Machining Technology for Improving the Service Life of Bearings

Abstract

The invention discloses a processing technology for improving the service life of bearings. Through a series of processing processes such as tube blank processing, rough material cutting, end face grinding, punching, inner and outer surface treatment, grinding extrusion, surface grinding, etc., the bearing processing During the coarse material process, the hardness of the raw material blank of the bearing is improved through multiple heat treatments. At the same time, the mandrel is extruded into the inner diameter of the bearing and passed through, so that the bearing expands in the radial direction, and the bearing is circled during the extrusion process. The tensile effect in the direction makes the surface of the bearing have the effect of cold work hardening, the surface is more dense, the comprehensive performance is further improved, and the service life of the bearing is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of bearing processing equipment, in particular to a processing technology for improving the service life of bearings. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, they are used to reduce friction. The coefficient of friction in the process of power transmission and the parts that keep the center of the shaft fixed, the bearing is an important part in contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the mechanical friction of the equipment during the transmission process Load friction coefficient. [0003] The Chinese invention patent with the publication number CN107457539A discloses a bearing processing tec...

AI Technical Summary

Problems solved by technology

[0004] 1. During the use of existing bearings, the tightness between the inner ring and outer ring of the bearing is poor, which reduces the service life of the bearing;

[0005] 2. During the grinding process of the bearing end face in the existing bearing processing technology, the same bearing needs to be clamped twice, which is time-consuming and laborious, and the grinding efficiency of the bearing end face is low
