Abstract
The invention relates to a corrosion-resistant and dry-grinding-resistant weight-carrying roller bearing comprising rollers 1, an isolator 2, a bearing inner ring 3, a bearing outer ring 4, an inner retainer ring 5 and an outer retainer ring 6, wherein the rollers 1 are placed between the bearing inner ring 3 and the bearing outer ring 4 and are isolated by the isolator 2. The rollers 1, the bearing inner ring 3 and the bearing outer ring 4 are each made of a gas-pressure sintered silicon nitride material; the inner retainer ring 5 and the outer retainer ring 6 are each made of a silicon nitride material; the isolator 2 is made of one of silicon carbide, silicon nitride, zirconium oxide and a polytetrafluoroethylene composite material. The weight-carrying roller bearing made of the material has corrosion resistance, temperature resistance and dry grinding resistance greatly improved and is suitable for machines which have the requirements on corrosion resistance, temperature resistance and dry grinding resistance and used for conveying petroleum, chemical media and other liquids in industries such as foods, petroleum, printing and dyeing, medicines, chemical industry, electroplating and the like.
Description
Technical field
The present invention relates to a kind of radial roller bearing, the radial roller bearing of particularly a kind of corrosion-resistant, anti-dry grinding.
Background technique
Along with the development of bearing industry, in order to meet different needs, there is various bearing, but the machinery of the liquid such as transfer oil and chemical mediator for industries such as food processing, oil, printing and dyeing, medicine, chemical industry, plating, corrosion-resistant to it, heatproof, 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
In order to solve the problem that above-mentioned prior art is difficult to overcome, the invention provides a kind of corrosion-resistant, resist in mill radial roller bearing, 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, separated by slider 2 between roller 1.
As a further improvement on the present invention, described roller 1 is gas Pressure Sintered Silicon Nitride roller.
As a further improvement on the present invention, described slider 2 the selection of material is the one in silicon carbide, silicon nitride, zirconium oxide and ptfe composite.
As a further improvement on the present invention, described bearing inner race 3 and bearing outer ring 4 the selection of material are gas Pressure Sintered Silicon Nitride.
As a further improvement on the present invention, the material that described inner shield ring 5 and outer back-up ring 6 are selected is silicon nitride.
The invention has the beneficial effects as follows: the radial roller bearing using above-mentioned material to make is wear-resisting, corrosion resistance is obtained for very large raising, is applicable in the machineries of industry in order to corrosion-resistant, high temperature resistant, the high pressure resistant requirement of having of the liquid such as transfer oil and chemical mediator such as food, oil, printing and dyeing, medicine, chemical industry, plating.

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, separated between roller 1 by slider 2, described slider 2 avoids the friction between roller 1, substantially reduces surface friction drag, reduces friction producing heat, extends the working life of radial roller bearing.The dense degree that roller 1 is placed regulates according to load by slider 2, more flexible, practical compared with the retainer structure adopted in prior art, this slider 2 the selection of material is the one in silicon carbide, silicon nitride, zirconium oxide and ptfe composite, and the material wear-resistant selected, corrosion resistant, heatproof, comprehensive mechanical performance are good.
Between bearing inner race 3 and bearing outer ring 4, be provided with inner shield ring 5 and the outer back-up ring 6 of 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, and the material corrosion resistant selected, wear-resisting property 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 radial roller bearing of the present invention, bearing inner race 3 and bearing outer ring 4 all select 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 that its cold-hot impact, self lubricity and comprehensive mechanical performance are good especially, not fragile, guarantee that radial roller bearing can Long-Time Service, extend the working life of radial roller bearing.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
