Abstract
The utility model relates to a corrosion-resistant and dry-grinding-resistant radial roller bearing comprising rollers 1, an isolator 2, an inner bearing ring 3, an outer bearing ring 4, an inner retainer ring 5 and an outer retainer ring 6, wherein the rollers 1 are placed between the inner bearing ring 3 and the outer bearing ring 4 and are isolated by the isolator 2. The rollers 1, the inner bearing ring 3 and the outer bearing ring 4 are respectively made of a gas-pressure sintered silicon nitride material; the inner retainer ring 5 and the outer retainer ring 6 are respectively made of a silicon nitride material; and the isolator 2 is made of one of silicon carbide, silicon nitride, berkelium oxide and a polytetrafluoroethylene composite. The radial roller bearing made of the material is greatly improved on corrosion resistance, temperature resistance and dry grinding resistance performances and is suitable for machines which are required to have the corrosion resistance, temperature resistance and dry grinding resistance performances and used for conveying petroleum, chemical media and other liquids in the industries such as foods, petroleum, printing and dyeing, medicines, chemical industry, electroplating and the like.
Description
Technical field
The utility model relates to a kind of radial roller bearing, particularly a kind of radial roller bearing of corrosion-resistant, anti-dry grinding.
Background technique
Along with the development of bearing industry, in order to meet different needs, various bearings are there are, but for the machinery of the liquid such as transfer oil and chemical mediator of the industries such as food processing, oil, printing and dyeing, medicine, chemical industry, plating,, heatproof corrosion-resistant to it, high voltage bearing characteristic requirements are higher, but the corrosion resistance that existing bearing is general and anti-dry grinding poor-performing, can not meet the demand of manufacturing machine.
Summary of the invention
The problem that is difficult to overcome in order to solve above-mentioned prior art, the utility model provides a kind of radial roller bearing of corrosion-resistant, anti-dry grinding, comprise roller 1, slider 2, bearing inner race 3, bearing outer ring 4, inner shield ring 5 and outer back-up ring 6, between bearing inner race 3 and bearing outer ring 4, place roller 1, between roller 1, separate by slider 2.
As further improvement of the utility model, described roller 1 is gas Pressure Sintered Silicon Nitride roller.
As further improvement of the utility model, described slider 2 the selection of materials are the one in silicon carbide, silicon nitride, zirconium oxide and ptfe composite.
As further improvement of the utility model, described bearing inner race 3 and bearing outer ring 4 the selection of materials are gas Pressure Sintered Silicon Nitride.
As further improvement of the utility model, the material that described inner shield ring 5 and outer back-up ring 6 are selected is silicon nitride.
The beneficial effects of the utility model are: use that the radial roller bearing made of above-mentioned material is wear-resisting, corrosion resistance is all greatly improved, be applicable to that the industries such as food, oil, printing and dyeing, medicine, chemical industry, plating are corrosion-resistant, high temperature resistant in order to having of the liquid such as transfer oil and chemical mediator, in the machinery of high pressure resistant requirement.

Embodiment
Embodiment: a kind of radial roller bearing of corrosion-resistant, anti-dry grinding, comprises roller 1, slider 2, bearing inner race 3, bearing outer ring 4, inner shield ring 5 and outer back-up ring 6.Between bearing inner race 3 and bearing outer ring 4, place roller 1, between roller 1, separate by slider 2, described slider 2 has been avoided the friction between roller 1, has greatly reduced surface friction drag, reduces friction producing heat, extends the working life of radial roller bearing.The dense degree that roller 1 is placed can regulate according to load by slider 2, retainer structure compared with available technology adopting is more flexible, practical, these slider 2 the selection of materials are the one in silicon carbide, silicon nitride, zirconium oxide and ptfe composite, and material wear-resistant, corrosion resistant, heatproof, the comprehensive mechanical performance selected are good.
The inner shield ring 5 and the outer back-up ring 6 that between bearing inner race 3 and bearing outer ring 4, are provided with protection roller 1 and slider 2, the material that described inner shield ring 5 and outer back-up ring 6 are selected is silicon nitride, material corrosion resistant, the wear-resisting property selected are good.
Gas Pressure Sintered Silicon Nitride material is a kind of novel stupalith, it is corrosion-resistant, wear-resisting, heat resistance is good, intensity is high, hardness is high, there is self lubricity, the roller 1 of the utility model radial roller bearing, bearing inner race 3 and bearing outer ring 4 are all selected gas Pressure Sintered Silicon Nitride material, the radial roller bearing of this kind of materials for support is corrosion-resistant, wear-resisting, heat resistance is good, the more important thing is its cold-hot impact, self lubricity and comprehensive mechanical performance are good especially, not fragile, guarantee that radial roller bearing can use for a long time, extend the working life of radial roller bearing.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
