Description
Technical field
The present invention relates to a kind of bearing and its preparation process, belong to metal material field.
Background technology
Bearing is a kind of important spare part in contemporary mechanical equipment, its major function is the mechanical rotary body of support, reduces it
Friction coefficient in motion process, and ensure its rotating accuracy.Operating of the bearing for machinery is indispensable, this just needs bearing
Itself there is preferable intensity and wear-resisting property.Bearing under normal conditions is prepared by material of steel alloy.
Steel alloy is based on iron, adds the elements such as a certain amount of carbon, molybdenum, manganese, at the same control addition element content and
The alloy system of composition.Steel alloy has high intensity, high rigidity and certain ductility, is suitable for making structural material, therefore wide
It is general to be applied in national defense industry and civilian industry, especially occupy critical role in the industries such as automobile, motorcycle, firearms.
Steel alloy used in traditional bearing, generally use pressure processing, makes processed steel (base, ingot etc.) produce plasticity
Deformation, is then divided to two kinds of cold working and hot-working according to steel alloy processing temperature difference.The main machining method of steel alloy has：Roll
System, casting, drawing group, extruding etc..Not only process is various for method, but also has also been short of in performance such as intensity, hardness of product etc..
It is low for conventional alloys steel hardness, it is not wear-resisting the shortcomings of, publication number 106609321A disclose it is a kind of by varying
Medium carbon steel bearing steel bearing outer ring heat treatment process improves the compression strength of product rubbing surface and rolling contact fatigue life.So
And the intensity that not can solve bearing, toughness, corrosion resistance and wear-resisting are only improved to heat treatment process
The problem of damage.
The content of the invention
For above-mentioned problem, the present invention provides high intensity, high tenacity, corrosion-resistant and high abrasion bearing.
To achieve these goals, the present invention uses following technical scheme：
A kind of bearing, the bearing includes the high molecular material outside bearing body and bearing body, wherein the bearing
Body is made of steel alloy, and the steel alloy is by following component and its mass percentage composition：Cd：0.05-0.07%, Mn：
0.5-1.5%, C：0.4-0.8%, Tl：0.08-0.12%, Cu：0.01-0.05%, Co：0.03-0.07%, surplus for Fe and
Impurity.
On the process for treating surface of traditional steel alloy, protected by modes such as brushing paint vehicle or plating,
But in use, it be easy to cause and comes off and fail.The pattern of the metal combination high molecular material of the present invention, utilizes chemistry
Reaction, metal surface is incorporated within the extremely short time by high molecular material, and high molecular material possess in itself higher-strength,
Hardness and corrosion resisting property, while waterproof, oxidation resistant effect can also be played.
Manganese has the characteristics that aboundresources, efficiency are various, and in steel alloy raw material proportioning of the invention, deoxidation is used as using manganese
Agent and desulfurizing agent, can not only effectively reduce the content of harmful element oxygen, sulphur in steel, while improve the hot-working character of steel, improve
The intensity and hardness of steel.The less addition element for steel alloy of cadmium, but a small amount of cadmium element can be acted on the copper in material
Formed in the disperse of hard copper alloy phase and steel, hence it is evident that lift the tensile strength and wearability of steel alloy.Effect of the thallium to steel alloy is non-
It is often important, the intensity of alloy can not only be improved, can also improve alloy rigidity, enhancing alloy corrosion performance, to extending the product longevity
The effect of life is very important.Meanwhile the bianry alloy phase that thallium is formed with cadmium, respective advantage can be combined, promote its own mutually
The lifting of effect, be not simple " 1+1 " combination for steel, but matter is leapt.
Preferably, in bearing raw material, the impurity includes P ＜ 0.04%, S ＜ 0.04%, N ＜ 0.04%, O ＜
0.03%.Impurity content is controlled it is possible to prevente effectively from being cracked after aluminium alloy casting solidification.
Preferably, the high molecular material outside bearing body includes the component of following parts by weight：16-20 parts of polyarylsulfone (PAS),
4-8 parts of polytetrafluoroethylene (PTFE), 3-5 parts of dimethyl sulfoxide (DMSO), 5-15 parts of phenyl ethylamine.High molecular material combine lightweight, high intensity it is excellent
Different in nature energy, has many reductions to the overall weight of bearing, while the polytetrafluoroethylene (PTFE) added can be effectively increased high molecular material
Wear-resisting property, extend life of product.
The present invention additionally provides another technical solution while reasonable selection material mixture ratio：
A kind of preparation process of bearing, the method include the following steps：
(1) dispensing：Raw material is weighed by the component and its mass percent of above-mentioned steel alloy, raw material is melted to form aluminium alloy
And pour into and semi-manufactured bearing is formed in mould；
(2) it is heat-treated：By semi-manufactured bearing carry out temper, annealing, then it is machined after be assembled into bearing；
(3) material is mixed outside：Raw material is weighed by the component and its number of above-mentioned high molecular material, by the raw material in addition to phenyl ethylamine
It is mixed and heated to be formed outside macromolecule and expects；
(4) steel modeling combines：Immersed with after plastics membrane closure bearing side in acid solution, keep 10-20min, then immerse containing benzene
In the solution of ethamine, it finally will expect to be ejected into bearing surface outside macromolecule, bearing completed products are obtained after solidification.
High tenacity is had concurrently with high intensity, the steel alloy of low brittle transition temperature is comparatively ideal structural material.Make material
Material obtains this comprehensive performance, can be optimized by changing processing technology.The present invention passes through the change to alloy Heat-Treatment of Steel
Change to optimize the internal structure of steel so that steel alloy is finer and close.Meanwhile using acid relatively low acid solution, in alloy steel body
Nano aperture is formed, is trapped in by phenyl ethylamine in hole, meanwhile, it is subject to the high molecular material based on polyarylsulfone (PAS) outside, can be in height
Molecular material chemically reacts when solidifying, finally so that steel alloy and high molecular material strong bonded, are ensureing product strength
In addition, product weight is reduced, saves cost.
Preferably, in step (2), heat treatment includes 2 isothermal tempers and 2 annealings.Change tradition
Simple tempering and annealing, can make it that steel internal structure is finer and close, lifts the comprehensive performance of steel.
Further optimization, the temperature of first time temper are 400-700 DEG C, and the temper time is 5-15min, second
The time of secondary temper is 1-5min；The temperature of annealing is 300-400 DEG C for the first time, and the annealing time is 1-
10min, the temperature of second of annealing is 200-300 DEG C, and the annealing time is 1-5min.Isothermal tempering processing can disappear
Except the residual stress inside steel, carry out while residual stress is eliminated to increase the compactness extent of steel at twice, improve steel
Intensity.And the annealing of different temperatures can increase the surface rigidity of steel, and simplify follow-up machining difficulty.
Further optimization, temper is with making annealing treatment alternately.Temper alternately can be with annealing
Change the thermal adaptability of steel alloy, crack is produced because of the unnatural change of ambient temperature when avoiding the product from using.
Preferably, in step (3), the heating-up temperature is 250-350 DEG C.By macromolecule mixing material be maintained at compared with
High-temperature, it is ensured that high molecular material is in a liquid state, easy to post-injection processing.
Preferably, in step (4), the acid solution is hydrochloric acid, the one or more in sulfuric acid, boric acid, acetic acid, acid solution
