Abstract
The invention discloses a bearing machining technology. The bearing machining technology includes the following steps: preparing materials of a bearing, machining the raw materials to obtain a rough blank, carrying out heat treatment on the rough blank, further carrying out liquid polishing after heat treatment is carried out, carrying out passivating treatment, grinding the rough blank obtained after the heat treatment, and assembling and combining parts. The bearing machined with the technology has the good corrosion resistance, and the service life is obviously prolonged.
Description
Technical field
The present invention relates to bearing part technical field, specifically a kind of bearing processing.
Background technology
Bearing is a kind of general part being widely used in machine industry.It is characterized in that rotating speed is high, load is large, frictional force is little, precision is high, can bear and come from radial and axial load.The dust cap of both sides plays dust-proof and effect that is that prevent lubricant grease excessive.The processing technology of this bearing is for a long time known by the technical staff of industry and grasp, traditional bearing adopts GCrl5 bearing steel, and the retainer that even pocket hole added by rolling element combination comprising an outer ring and an inner ring and some reaches roll body uniform distribution the object of uniform stressed on raceway.Bearing dustproof cover is compressed in the alveolus of outer ring.Prior art is under larger axial load effect, and the problem of rib fracture is difficult to process, and toughness is just smaller comparatively speaking, is therefore subject to axial force time ratio and is easier to fracture.
Summary of the invention
The object of this invention is to provide a kind of bearing processing.
A kind of bearing processing, comprises the following steps:
(1) material of bearing is prepared: lasso (inner ring and outer ring) and rolling element material are: high-carbon-chromium bearing steel, Gcr15,40Cr1Ni2A stainless steel, and retainer material is: brass HPb59-1, bronze QAL10-3-1.5, aluminium alloy LY11CZ;
(2) forging processing, turnery processing are carried out to raw material, obtain the thick embryo of each parts of bearing;
(3) heat-treat thick embryo, heat treatment comprises Quench and temper, and quenching is heated to 800 DEG C-900 DEG C, and insulation 30min is placed in cooling oil quenching; Tempering is heated to 170 DEG C-200 DEG C, and insulation 6h, cools naturally;
(4) also carry out liquid after heat treatment and throw process, inner ring, outer ring in stainless steel bearing are positioned in centrifugal drum rolling, by adding high frequency porcelain ball and polishing fluid adds a certain amount of water again; Part by weight is sequentially 12:28:8:40, temperature 30 DEG C-70 DEG C;
(5) Passivation Treatment;
(6) grinding is carried out to the thick embryo after heat treatment;
(7) by each parts assembly.
Preferably, described step (5)) in passivating solution be in the hydrochloric acid of 100m1, add 2g calcium bichromate powder, stirring and dissolving.
Beneficial effect of the present invention: the bearing adopting processes of the present invention, have good corrosion resistance, service life significantly improves.
