Abstract
The utility model relates to a spherical oilless bearing, comprising an inner sleeve and an outer sleeve and the outer sleeve is arranged with inner rings and outer rings, wherein an outer ring 3 is made of bearing steel,and an inner ring 2 is made of alloys and consistent lubricant microspheres coating powdered-metal on the external surface. The inner edge of the outer ring 3 is a concave surface, and the inner and outer edges of the inner ring 2 are male and female type surfaces. The inner rings and outer rings are in interference fit. An inner sleeve 1 of the bearing is provided with an identical material quality with the outer ring 3 and in spherical design as the outer ring 3 and accomplishes loading and unloading by a dap 4. The utility model is arranged with an anti-friction bearing operated in extreme conditions such as high temperature, heavy duty, and dust-laden environment, and has the advantages of a strong intensity, a simple structure, a low operating noise, and a long operating life. In addition, the utility is refueling free and water-cooling free in operation and can be extensively applied in high-temperature mechanical fields.
Description
The utility model relates to a kind of self oiling bearing, relates in particular to a kind of spherical aligning oil-less self-lubricating bearing.
Self oiling bearing be mainly used in be difficult for forming oil film heavy duty, high temperature, vacuum, steam, many dirt arranged and be difficult for adding in the machinery under the lubricated wet goods operating conditions.In the prior art, self oiling bearing roughly is divided into following several: the self oiling bearing that (1) single powdered metallurgical material constitutes, this bearing not only causes the serious waste of material, and intensity is also lower, easily cause the malformation of pulling in running-in period, be difficult to be fit to the operating conditions of high loading or HI high impact with bearing; (2) the sintering bimetal self-lubricating bearing is meant with the metal of powder metallurgy process manufacturing and the sliding bearing of metal or metal and non-metal/composite material, and steel backing-sintered alloy bimetallic bearing.Though this bearing has solved strength problem, the surface layer abrasion-proof performance is still undesirable, can not be used for the operating mode occasion of heavy duty; (3) inserted bimetal solid self-lubricating plain bearing, the described bearing of Chinese patent CN 2323189Y is this kind bearing.Though this bearing has certain advantage, but because the solid lubricant that embeds is different with the thermal expansion coefficient of matrix, under high temperature and thump, solid lubricant easily drops out and causes abrasive wear, the solid lubricant of Qian Ruing does not have flowability simultaneously, can't take away by fricative heat, more aggravate its wearing and tearing, so Embedded Double metal solid self oiling bearing should not be used in heavy duty, lack again in the environment of cooling measure at a high speed; (4) modified model self-lubricating solid bearing, this class bearing have carried out certain improvement on original basis, but still have the use narrow limitation.The self oiling bearing that Chinese patent 93228570.8 relates to also is jacket structure in the spherical aligning, but its overcoat one side has elastic opening, this has reduced the rigidity of bearing, simultaneously, the inner ring of bearing is designed to self lubricating material, this easily causes mill axle and abrasive material to pollute the working life of reducing bearing greatly; The self oiling bearing that Chinese patent 89208353.0 relates to, form by inner ring, outer ring and loose bush, loose bush is made up of SF material internal layer and metallic copper skin, as everyone knows, the SF material has the corrosion-resistant advantage, but its heat resistance is relatively poor, be not suitable for the place of high temperature, and metallic copper is the soft metal, and very easily distortion under HI high impact influences the using effect of bearing.
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of can work under bad working environments conditions such as high temperature heavy load, and intensity is higher, dimensionally stable, lubricated good and wear-resisting novel spherical aligning oil-less self-lubricating bearing.
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of can work under bad working environments conditions such as high temperature heavy load, and intensity is higher, dimensionally stable, lubricated good and wear-resisting novel spherical aligning oil-less self-lubricating bearing.
The utility model is made up of interior cover and overcoat, and its technical characterstic is that overcoat is the Internal and external cycle structure, and its Internal and external cycle and interior cover male and fomale(M﹠F) each other cooperate, and the interior outer rim of inner ring is a male and fomale(M﹠F), and the inner edge of outer ring is a concave surface; The outer rim of interior cover is a convex surface, and symmetry has notch on inner ring, and outer ring and interior cover are Bearing Steel, and inner ring is the solid lubricant alkanol-substituted DMH compounds of alloy and outer surface clad metal powder, and Internal and external cycle is an interference fit.
Description of drawings
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 and Fig. 2 are structural representation of the present utility model.
Embodiment
Technical characterstic of the present utility model is the spherical bearing of overcoat in rolling bearing is designed to.Sliding bearing is made up of Internal and external cycle, and the inner edge of outer ring 3 is designed to concave surface, and the interior outer rim of inner ring 2 is designed to male and fomale(M﹠F), and the outer rim of interior cover 1 then is a convex surface; The convex surface of interior cover 1 cooperates with the concave surface of inner ring 2, and the convex surface of inner ring 2 matches with the concave surface of outer ring 3, has notch 4 so that install on the concave surface of inner ring 2.Inner ring 2 is a self lubricating material, i.e. the solid lubricant alkanol-substituted DMH compounds of outer surface clad metal powder and adopt interference fit with the bearing rigidity material of outer ring 3 makes it and the interior cover 1 self oiling bearing friction pair that partners, and has avoided the generation of mill axle phenomenon.Simultaneously, inner ring 2 has not only reduced running noises with the adjustable distance of interior cover 1, and, prolonged the working life of bearing for the Internal and external cycle structure of the good fit space that provides, the especially interference fit of friction pair under the hot operation condition has improved the intensity and the impact resistance of powdered metallurgical material.
The utility model is simple and reasonable, can be widely used under the bad working environments of high temperature, heavy duty, thump, is a kind of desirable self oiling bearing.
