Abstract
The utility model relates to an annular bearing1 which comprises an inner ring and an outer ring. The annular bearing is characterized in that both the inner ring and the outer ring are made of porcelain. The annular bearing1 takes porcelain as material to make the inner ring and the outer ring, and since porcelain is wear-resistant, high temperature-resistant and corrosion-resistant, the annular bearing can greatly improve service life and efficiency of the fuel pump of an automobile. The annular bearing is smooth and bright at surface, without pores and cracks, so friction is small, thus further improving the service life and the efficiency of the fuel pump of the automobile. Since the annular bearing is smooth at surface, no lubrication is needed and the annular bearing will not be radiated by gasoline. Sintered under high temperature, the surface of the ceramic annular bearing is hard, smooth and bright, thus greatly reducing the friction between the annular bearing and a shaft core during rotation, making the rotation of the rotating shaft of a motor more flexible, and helping the user save the trouble of worrying about that the lubricating oil will be thrown out due to temperature rise during rotation.
Description
Technical field
The utility model relates to a kind of mechanical part, particularly a kind of annular bearing.
Background technique
Be oil-containing copper base bearing, powder oil-impregnated bearing, rolling bearing at the annular bearing that uses at present, they are not suitable for being placed in the radiativity product, particularly on the fuel pump of automobile.This be since gasoline to the lubricated solvation that plays in the product, when turning round in a period of time, axle and heat that oil-impregnated bearing produces and high speed rotating can throw away the lubricant oil in the oil-impregnated bearing, cause lacking lubricant oil at high speed rotating between axle and the oil-impregnated bearing, can accelerate to rub between the two after the rotation heating between them to damage thereby make owing to powder bearing stampings density is low, the friction rotor of motor is made a noise, cause the fuel pump cisco unity malfunction, also can't change inner oil-impregnated bearing, can cause the wasting of resources of various economic losses and other parts.
Summary of the invention
The technical problems to be solved in the utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of annular bearing is provided, and this bearing has very high wear resistance, high temperature resistant, corrosion-resistant.
The technical solution adopted in the utility model is:
Annular bearing, described annular bearing includes inner ring and outer ring, it is characterized in that described inner ring and described outer ring are ceramic inner ring and ceramic outer ring.
Further, in the annular bearing of the present utility model, the smooth surface of described ceramic inner ring and ceramic outer ring.
Further, in the annular bearing of the present utility model, described ceramic inner ring and ceramic outer ring are through the ceramic inner ring of high temperature sintering and ceramic outer ring.
Compared with the prior art annular bearing of the present utility model has following good effect: adopt the material of pottery as inner ring and outer ring, pottery itself has wear resistance, high temperature resistant, corrosion resistant characteristic, thereby makes this annular bearing can improve the working life and the efficient of automobile fuel pump greatly; Smooth surface is glossy, does not have any pore and the Silk Road, makes its frictional force little, thereby further strengthens the working life and the efficient of fuel pump; Because their smooth surfaces do not need to lubricate, can't be by the gasoline radiation; Because holding through high temperature, burns the ceramic ring profile shaft, there is very strong hardness of one deck on the knot surface, and is and smooth glossy, reduce greatly and the axle core between when rotated frictional force, make machine shaft more flexible, and do not worry because when running heats up that lubricant oil is thrown away in rotation.
Description of drawings
Fig. 1 represents that annular bearing of the present utility model is assemblied in the structural representation in the fuel pump.
Embodiment
With reference to accompanying drawing 1, will be described in detail embodiment of the present utility model.
The utility model relates to a kind of annular bearing 1, and described annular bearing includes inner ring and outer ring, it is characterized in that described inner ring and described outer ring are ceramic inner ring and ceramic outer ring.Adopt the material of pottery as inner ring and outer ring, pottery itself has wear resistance, high temperature resistant, corrosion resistant characteristic, thereby makes this annular bearing can improve the working life and the efficient of automobile fuel pump greatly.
Further, in the annular bearing of the present utility model, the smooth surface of described ceramic inner ring and ceramic outer ring.Smooth surface is glossy, does not have any pore and the Silk Road, makes its frictional force little, thereby further strengthens the working life and the efficient of fuel pump.Because their smooth surfaces do not need to lubricate, can't be by the gasoline radiation.
Further, in the annular bearing of the present utility model, described ceramic inner ring and ceramic outer ring are through the ceramic inner ring of high temperature sintering and ceramic outer ring.Because holding through high temperature, burns the ceramic ring profile shaft, there is very strong hardness of one deck on the knot surface, and is and smooth glossy, reduce greatly and the axle core between when rotated frictional force, make machine shaft more flexible, and do not worry because when running heats up that lubricant oil is thrown away in rotation.Because this product has self-lubricating function, add when being immersed in fuel oil also is that lubricated and refrigerating function are arranged, finish in the rotating shaft that reaches high speed rotating, because its surface hardness height is glossy again, friction factor is low, improve the working life and the performance of motor bearings greatly, reduced noise that product sent in the running and unusual.
Annular bearing of the present utility model, can produce rotation or close-fitting with endoporus and axle during use all is well to rotate the flexible design structure with external diameter and other materials rotation on axle.When mounted, external diameter is pressed onto in the end cap of motor, ceramic bearing can certainly be fixed on the core, ceramic bearing or the other materials with the outside forms rotation relationship again.Wherein fixed dimension can adopt round or square or water caltrop is polygonal.
Fig. 1 is assemblied in structural representation in the fuel pump with annular bearing of the present utility model, when assembling, according to the external diameter processing electric motor end cap of ceramic bearing, close-fitting is to the center, rear-most end is stayed a step, prevents to slide behind the ceramic bearing, and two ends all adopt its effect meeting of this product better.
Claims (2)
1, annular bearing, described annular bearing includes inner ring and outer ring, it is characterized in that described inner ring and described outer ring are ceramic inner ring and ceramic outer ring.
2, annular bearing according to claim 1 is characterized in that described ceramic inner ring and ceramic outer ring are ceramic inner ring and the ceramic outer rings through high temperature sintering.
