Machining technology prolonging service life of bearing

Abstract

The invention discloses a machining technology prolonging the service life of a bearing. Through a series of machining processes such as pipe blank machining, coarse material cutting, end surface grinding, punching, inner and outer surface processing, grinding extrusion and surface grinding, in the bearing coarse material machining process, a raw blank of the bearing is better in hardness throughmultiple times of heat treatment, meanwhile, a mandrel is extruded into the inner diameter of the bearing and passes through the bearing, and thus, the bearing is expanded in the radial direction; thecircumferential stretching effect on the bearing in the extrusion process is achieved, accordingly, the surface of the bearing has a cold hardening effect, the surface is more compact, the comprehensive performance is further improved, and the usage period of the bearing is prolonged to a great extent.

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...
