Abstract
The utility model relates to a self-lubricating bearing sleeve, which belongs to the technical field of machinery and solves the problem that a bearing in the prior art cannot be continuingly used in the case of no lubricant oil. The self-lubricating bearing sleeve comprises a barrel-shaped body, wherein the body is made from a stainless steel material; a wear-resistant layer is formed on the inner wall of the body by virtue of quenching and tempering, and salt bath co-penetration; a transition layer is further formed between the body and the wear-resistant layer; a lubricant layer is formed at the outer side of the wear-resistant layer by spraying molybdenum disulfide. According to the self-lubricating bearing sleeve, the body is made from the stainless steel material, thus the bearing is not liable to rust in a wet environment; in addition, the wear-resistant layer and the lubricant layer are formed after carrying out a QPQ (quench-polish-quench) treatment at the outer side of the bearing, thus the bearing sleeve is capable of continuing to keep lubrication in an oilless case on the premise of ensuring wear resistance.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of bearing sleeve, particularly a kind of self oiling bearing lining.
Background technique
Self oiling bearing is by metallic matrix bearing load, the solid lubricant lubricate of special formulation.The features such as it is high that it has bearing capacity, shock-resistant, high temperature resistant, and selflubricating ability is strong, are specially adapted to heavy duty, low speed, back and forth or swing etc. be difficult to lubricated and form the occasion of oil film, the also etch of not water funk punching and other acid solution and washing away.Be widely used in metallurgy conticaster, rolled firm equipment, in mining machinery, mould, Hoisting Machinery, textile manufacturing machine, wind-powered electricity generation generating, boats and ships, steam turbine, water turbine, injection machine and device fabrication production line.
And at confined space, moist and unlubricated, high-mechanic, under the specific work environments of HI high impact, common steel sleeve gets rusty easily, and can not under unlubricated condition, work.If in use lubrication oil supply deficiency, can cause bearing running hot, kill even and scrap, affect the working life of machine.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of wear-resisting property good, the self oiling bearing lining that is difficult for getting rusty.
The purpose of this utility model can realize by following technical proposal: a kind of self oiling bearing lining, comprise tubular body, it is characterized in that, described body adopts stainless steel material to make, inner body wall is oozed formation wearing layer altogether by quenching with Subsequent tempering and salt bath, between described body and wearing layer, be also formed with transition layer, described wearing layer outside is also provided with lubricating layer.
In above-mentioned self oiling bearing lining, described body adopts SUS203 stainless steel material to make.SUS203 stainless steel material refers to the steel of the chemical etching dielectric corrosions such as the weak aggressive medium such as resistance to air, steam, water and acid, alkali, salt.Be applied to humidity and unlubricated, under the working environment of high-mechanic, HI high impact, can ensure that lining is difficult for getting rusty.
In above-mentioned self oiling bearing lining, described transition region thickness is 0.5mm, and wearing layer thickness is 0.02mm, and lubricating layer thickness is 0.02mm.
In above-mentioned self oiling bearing lining, described wearing layer adopts QPQ to process and forms.QPQ technique is after workpiece has been made to salt bath compounding, in order to reduce the roughness of workpiece surface, workpiece surface is carried out to stock removal polishing, and then in salt bath, make once oxidation, by QPQ salt bath composite treatment technology, can increase substantially wear resistance, the corrosion stability of metal surface, and workpiece deforms hardly, this technology has realized the compound of nitriding operation and oxidation operation; Nitride and oxide compound; Wear resistance and corrosion stability compound; Heat treatment technology and aseptic technic compound.For preventing, in QPQ processing procedure, sleeve outer surface is also formed to wearing layer, while making lining assembling, there is skidding, after QPQ processes, its outer surface is carried out to grinding processing, making its outer surface is to be directly stainless steel body.
In above-mentioned self oiling bearing lining, described lubricating layer adopts molybdenum disulfide spraying to form.The object of lubricating layer is further to strengthen the greasy property of sleeve lining, and axle sleeve and axle can be effectively lubricated in running-in period.Molybdenum disulfide is after chemical purification, to change structure of molecule and the solid powder made by natural molybdenum concntrate powder.Its look black silver grey of being slightly with, has metallic lustre, and that touches has a soapy feeling, water insoluble.Product has good dispersion, and inadherent advantage can be added in various greases, forms exhausted inadherent colloidal state, can increase lubricity and the extreme pressure property of grease, is applicable to the machine work state of high temperature, high pressure, high rotating speed high load, the extension device life-span.Antifriction when molybdenum disulfide is low temperature for friction material major function, increases and rubs when high temperature, and ignition loss is little, volatile in friction material.
Compared with prior art, this self oiling bearing lining is by adopting stainless steel material to make body, make bearing be difficult for getting rusty under wet environment, carry out after QPQ processes forming wearing layer and lubricating layer in bearing outside in addition, ensureing under the prerequisite of wear resistance, making bearing sleeve keeping lubricated without continuing under oil condition.
Brief description of the drawings
Fig. 1 is the sectional structure schematic diagram of this self oiling bearing lining.
In figure, 1, body; 2, transition layer; 3, wearing layer; 4, lubricating layer.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this self oiling bearing lining, comprise tubular body 1, described body 1 adopts stainless steel material to make, described body 1 inwall is oozed altogether and is formed wearing layer 3 by quenching with Subsequent tempering and salt bath, between described body 1 and wearing layer 3, be also formed with transition layer 2, described wearing layer 3 outsides are also provided with lubricating layer 4.Described body 1 adopts SUS203 stainless steel material to make.SUS203 stainless steel material refers to the steel of the chemical etching dielectric corrosions such as the weak aggressive medium such as resistance to air, steam, water and acid, alkali, salt.Be applied to humidity and unlubricated, under the working environment of high-mechanic, HI high impact, can ensure that lining is difficult for getting rusty.Described wearing layer 3 thickness are 0.02mm, and transition layer 2 thickness are 0.5mm, and lubricating layer 4 thickness are 0.02mm.Described wearing layer adopts QPQ to process and forms.QPQ technique is after workpiece has been made to salt bath compounding, in order to reduce the roughness of workpiece surface, workpiece surface is carried out to stock removal polishing, and then in salt bath, make once oxidation, by QPQ salt bath composite treatment technology, can increase substantially wear resistance, the corrosion stability of metal surface, and workpiece deforms hardly, this technology has realized the compound of nitriding operation and oxidation operation; Nitride and oxide compound; Wear resistance and corrosion stability compound; Heat treatment technology and aseptic technic compound.For preventing, in QPQ processing procedure, sleeve outer surface is also formed to wearing layer, while making lining assembling, there is skidding, after QPQ processes, its outer surface is carried out to grinding process, making its outer surface is to be directly stainless steel body.
