Abstract
The invention discloses a processing technology for a bearing. The processing technology for the bearing comprises the following steps: forging; machining; carburizing; and heat treating. The bearing is made from stainless steel. After the heat treating is carried out, liquid polishing treatment is further conducted. According to the liquid polishing treatment, an inner ring and an outer ring in the stainless steel bearing are placed in a centrifugal drum. The liquid polishing treatment is carried out through adding of high-frequency porcelain balls and polishing solution. After the liquid polishing is carried out, passivating treatment is further conducted. Aiming at solving the problem that the bearing is easy to crack when axial force is born in the prior art, the invention provides the processing technology for the stainless steel bearing which not only has the mechanical performance of a common bearing, but also has a better performance of corrosion resistance.
Description
Technical field
The present invention relates to technical field of bearings, specifically a kind of bearing processing.
Background technology
Bearing is a kind of general part that is 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 dustproof and prevents the effect that lubricant grease is excessive.The processing technology of this bearing is known and grasps by the technical staff of industry for a long time, traditional bearing adopts the GCrl5 bearing steel, and the retainer that the rolling element that comprises an outer ring and inner ring and some in combination is added even pocket hole reaches the roll body uniform distribution purpose 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, time that therefore is subject to axial force ratio be easier to fracture.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of bearing processing for above-mentioned prior art, it is characterized in that, comprises forging, Vehicle Processing, carburizing, heat treatment.
Described bearing material adopts the 40Cr1Ni2A stainless steel.
Also carry out liquid after described heat treatment and throw processing.
It is that inner ring, outer ring in stainless steel bearing are positioned in centrifugal drum rolling that described liquid is thrown treatment process, adds a certain amount of water by adding high frequency porcelain ball and polishing fluid again; Part by weight sequentially is 15:30:6:45,30 ℃-70 ℃ of temperature,
Also carry out Passivation Treatment after after described liquid is thrown and processed, passivating solution is to add 2g calcium bichromate powder, stirring and dissolving in the hydrochloric acid of 100m1.
Described heat treatment comprises quenches and tempering, and quenching is to be heated to 600 ℃-900 ℃, and insulation 30min is placed in cooling oil quenching; Tempering is to be heated to 100 ℃-200 ℃, and insulation 6h is naturally cooling.
The invention provides a kind of mechanical performance that had both possessed plain bearing, have again the processing technology of the stainless steel bearing of good corrosion resistance.
The specific embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
Material adopts the 40Cr1Ni2A stainless steel, forges Vehicle Processing, carburizing, heat treatment, liquid is thrown and is processed and Passivation Treatment, it is that inner ring, outer ring in stainless steel bearing are positioned in centrifugal drum rolling that liquid is thrown treatment process, adds a certain amount of water by adding high frequency porcelain ball and polishing fluid again; Part by weight sequentially is 15:30:6:45, and temperature 70 C, passivating solution are to add 2g calcium bichromate powder in the hydrochloric acid of 100m1, stirring and dissolving, and processing comprises quenches and tempering, and quenching is to be heated to 900 ℃, and insulation 30min is placed in cooling oil quenching; Tempering is to be heated to 200 ℃, and insulation 6h is naturally cooling.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
