Abstract
The present invention comprises a nonmetal light bearing which comprises an inner ring, an outer ring, a retainer and a plurality of rolling balls, wherein the rolling balls are fixed to a rolling path between the inner ring and the outer ring by the retainer in an equidistance mode. Materials used by the inner ring, the outer ring and the retainer comprise the components (volume proportion) of 95 to 99% of teflon and 1 to 5% of polyisobutylene, and the rolling balls are made of ceramics, glass, agate or crystal. Because the inner ring, the outer ring and the retainer are made of teflon and polyisobutylene, the present invention has the advantages of good abrasive resistant performance, good corrosion prevention performance, good acid protection performance, good alkali prevention performance, good high temperature resistant performance, good low temperature resistant performance and self-lubricating performance, and any lubricator does not need to be added. Thus, the present invention is suitable for the technical fields with special requirements of medical preparation, chemical engineering, printing, food, outdoor machinery, etc. The polyisobutylene reduces the viscosity of a melted body of the teflon, and thus, the injection molding of the present invention is easy.
Description
Technical field
The present invention relates to a kind of bearing, particularly a kind of nonmetal underloading rolling bearing.
Background technique
Bearing is widely used in mechanical field, mainly contain two kinds on sliding bearing and rolling bearing, but not metal is mainly used in sliding bearing.Yet there are no in the prior art teflon is used for rolling bearing.
Traditional material that rolling bearing adopted is a metal, at some special dimension, as fields such as pharmacy, chemical industry, printing and dyeing, food, outdoor machinery, because anticorrosion, the acid-proof of metal bearing, alkali prevention, water-fast performance have certain narrow limitation, in use must be in outer surface coating one deck coating of bearing, and need make with lubricator, this just has pair Environmental Conditions to have higher requirement or just might produce harmful effect to the special dimension that uses, and manufacture cost also increases greatly simultaneously.
Plastic bearing material commonly used mainly contains polyoxymethylene, polyamide, teflon, polybenzoate etc.What use is polyoxymethylene and polyamide the most widely, and its wear resistance is good, and moulding process is convenient, but its continuous serviceability temperature only is 100 degrees centigrade, and the short-term serviceability temperature is 130 degrees centigrade, can not work under higher temperature; Teflon and polybenzoate have good scratch-resistant performance, can use continuously down at 250 degrees centigrade, but its melt viscosity are too high, is difficult to injection moulding.
As seen, above-mentioned all bearings all have its narrow limitation, therefore, develop a kind of fields such as pharmacy, chemical industry, printing and dyeing, food, outdoor machinery that are applicable to, need not make with lubricator, anticorrosion, acid-proof, alkali prevention, water-fast, high temperature resistant, low temperature resistant performance are good, and the simple bearing of moulding process, are highly significant.
Summary of the invention
The invention provides a kind of nonmetal spigot bearing, overcome the bearing defective not strong of prior art the adaptability of special dimension.
The technical solution used in the present invention is: comprise inner ring, outer ring, retainer and plurality of balls, retainer is with in the equidistant raceway that is fixed between inner ring and the outer ring of ball, each component and volume ratio thereof that the material that inner ring, outer ring and retainer are adopted comprises are: teflon 95-99, polyisobutylene 1-5, the material that ball adopts is pottery, glass, agate or crystal.
The present invention is because inner ring, outer ring and retainer adopt teflon and polyisobutylene, therefore wear resistance is good, anticorrosion, acid-proof, alkali prevention, high temperature resistant, low temperature resistant performance are good, and has self lubricity, need not add any oiling agent, therefore be adapted to the field that pharmacy, chemical industry, printing and dyeing, food, outdoor machinery etc. have specific (special) requirements, and polyisobutylene reduced the viscosity of teflon melt, made its easy injection moulding.
Embodiment
One embodiment of the present of invention, comprise inner ring, outer ring, retainer and plurality of balls, retainer is with in the equidistant raceway that is fixed between inner ring and the outer ring of ball, each component and volume ratio thereof that the material that inner ring, outer ring and retainer are adopted comprises are: teflon 95-99, polyisobutylene 1-5.
The material that ball adopts is pottery, glass, agate or crystal.
Teflon has the excellent properties of insulation, corrosion protection, ageing-resistant, anti-microwave, selflubricating, is widely used in each production, sphere of life; Polyisobutylene is colourless, tasteless, nontoxic, have better chemical stability and good antioxygen, anti-ozone, acid resistant alkali and anti-ultraviolet performance, and electrical insulating property is good, and the excellent properties of selflubricating is also arranged.The teflon melt viscosity is too high, is difficult to injection moulding.The present invention adds a spot of polyisobutylene in teflon, can lower the viscosity of teflon melt, therefore can adopt the injecting method moulding.Polyisobutylene also can increase the self-lubricating property of bearing, can determine the consumption of polyisobutylene according to different use occasions.The shared volume ratio of polyisobutylene is 1 in the present embodiment, and being suitable for if greasy property is had relatively high expectations, can suitably increase the shared volume ratio of polyisobutylene to the occasion of the greasy property requirement end of than.
The manufacture method of this bearing is as follows: by formula ratio teflon and polyisobutylene charge are put into the injection machine pressurization of heating and mix, when treating that it becomes the melt shape, in the mould of injection bearing inner ring, outer ring and retainer, after the moulding raceway is processed.And then the machining of non-metallic ball, more inside and outside circle, retainer and ball are assembled at last.
The inside and outside circle of this bearing and the hardness of retainer can be long-term used in minimum temperature and reach-269 degree Celsius up to Shao Shi D50-65, and maximum temperature reaches 250 degree Celsius.
Another embodiment of the present invention, be with embodiment one difference, each component and volume ratio thereof that the material that its inner ring retainer and outer ring retainer are adopted comprises are: teflon 97, polyisobutylene 3, this bearing are applicable to that degree of lubrication requires general occasion.
Another embodiment of the present invention, be with embodiment one difference, each component and volume ratio thereof that the material that its inner ring retainer and outer ring retainer are adopted comprises are: teflon 95, and polyisobutylene 5, this bearing is applicable to the occasion that degree of lubrication is had relatively high expectations.
Claims (1)
1, a kind of nonmetal spigot bearing, comprise inner ring, outer ring, retainer and plurality of balls, retainer is with in the equidistant raceway that is fixed between inner ring and the outer ring of ball, it is characterized in that each component and volume ratio thereof that material that inner ring, outer ring and retainer are adopted comprises are: teflon 95-99, polyisobutylene 1-5, the material that ball adopts is pottery, glass, agate or crystal.
