Abstract
The invention relates to an oil storage cavity bearing steel bushing, belongs to the technical field of machines, and solves the problem of weak lubricating performance of the oil storage cavity bearing steel bushing in the prior art. The oil storage cavity bearing steel bushing comprises a barrel-shaped main body, wherein a plurality of evenly distributed oil storage cavities are formed in the inner wall of the main body; a circular oil conducting groove is formed in the middle of the inner wall of the main body; a plurality of oil inlet holes are evenly distributed in the inner wall of the main body in the peripheral direction of the oil conducting groove. The oil storage cavity bearing steel bushing adopts the oil storage cavities to store oil, so that the oil storage area and oil storage quantity of the inner wall of the main body are increased, and the lubrication of a shaft sleeve is convenient; meanwhile, the QPQ processing is implemented for the main body to improve the hardness, wear resistance and corrosion resistance of the main body; in addition, molybdenum disulfide is sprayed on the inner wall of the main body to bring convenience to the running-in in the initial utilization period; the oil storage cavity bearing steel bushing has the advantages of good lubricating performance and low frictional wear.
Description
Technical field
The invention belongs to field of mechanical technique, relate to the bearing in a kind of Machine Movement Process, particularly a kind of bearing steel bushing.
Background technique
Bearing steel bushing 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.
At present, generally all need to offer oil groove in axle sleeve, the effect of oil groove is lubricant oil to inject sleeve lining, by oil groove, lubricant oil is delivered to sleeve lining arbitrary position.In prior art, the form of oil groove mainly contains " 8 " word oil groove, helical oil groove, endless-oil groove, straight oil groove etc.Its oil groove oil reserve is little, should not store, and easily loss, tank structure is inhomogeneous, has a lot of lubricated blind areas, causes product lubricated insufficient in the process of using, thus quick abrasion product short problem in working life.
Summary of the invention
The object of the invention is to have the problems referred to above for existing technology, proposed the bearing steel bushing that a kind of oil reserve is large.
Object of the present invention can realize by following technical proposal: a kind of oil storage cave bearing steel bushing, it is characterized in that, comprise tubular body, described inner body wall is provided with several uniform oil storage caves, described inner body wall middle part is provided with annular oil guide slot, and described inner body wall is circumferentially evenly equipped with several oil inlet holes along oil guide slot.
During the work of this bearing steel bushing, by oil inlet hole, lubricant oil is injected to inner body wall, lubricant oil enters oil storage cave under the leading role of oil guide slot, by uniform oil storage cave structure, improve oil reserve, its catchment area can account for the more than 25% of sleeve lining surface area, carries out comprehensive lubricated while facilitating bearing action.
In above-mentioned oil storage cave bearing steel bushing, described oil inlet hole is three and is circumferentially distributed in body middle part.
In above-mentioned oil storage cave bearing steel bushing, described inner body wall adopts QPQ to process.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.
In above-mentioned oil storage cave bearing steel bushing, described inner body wall is provided with solid lubricant layer.The object of solid lubricant layer is further to strengthen the greasy property of sleeve lining, and axle sleeve and axle can be effectively lubricated in running-in period.
In above-mentioned oil storage cave bearing steel bushing, described solid lubricant layer adopts molybdenum disulfide spraying to form.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 during high temperature, and ignition loss is little, volatile in friction material.
Compared with prior art, this oil storage cave bearing steel bushing adopts oil storage cave to carry out oil storage, improve inner body wall catchment area and oil reserve, facilitate the lubricated of axle sleeve, body is carried out to QPQ processing simultaneously, improve body hardness, wear resistance and corrosion stability, in addition, at inner body wall spraying molybdenum disulfide, contribute to body to use the break-in at initial stage, there is greasy property good, the advantage that fretting wear is little.
