Abstract
A superhigh molecular composite bearing relates to equipment in the technical fields of precision machine tool, aerospace, navigation, nuclear industry, petroleum, chemical industry, textile industry, machinery, metallurgy, electric power, food, locomotive, subway, high speed machine tool, science research, national defense and military and the like and equipment which needs to operate under special conditions such as high speed, deep cryogenic, inflammable, explosive, highly caustic, vacuum, electrical isolation, nonmagnetic and dry friction conditions and the like. The composite bearing is a perfect combination of novel materials and novel technologies, and has characteristics of washing resistance, cold resistance, wear resistance, corrosion resistance, diamagnetic electrical isolation, oil-free self-lubrication, no noise, light weight, long service life and the like.
Description
Affiliated technical field:
A kind of ultra-high molecule composite bearing that the present invention relates to fields such as precision machine tool, Aero-Space, navigation, nuclear industry, oil, chemical industry, light and textile industries, machinery, metallurgy, electric power, food, locomotive, subway, high-speed machine tool and scientific research national defense and military technology or need on field such as work under the special operation conditions such as high speed, deep cooling, inflammable, explosive, deep-etching, vacuum, electrical insulation, no magnetic, dry friction, use; It is the perfect adaptation of new material, new process; The ultra-high molecule composite bearing have anti-ly wash away, resist cold, characteristic such as wear-resisting, corrosion-resistant, diamagnetic electrical insulation, oil-free self lubrication; And the ultra-high molecule composite bearing is noise free at work; In light weight, thermal expansion coefficient is little, and be 3 times of existing bearing working life; Can save a large amount of maintenance downtimes; The rate of reducing the number of rejects and seconds reduces stock's bearing spare part, has improved the manufacturing efficiency of whole system greatly.
Background technique:
At present, the structure of known bearing is by inside and outside circle steelframe, metal rolling element; Metal retainer and Sealing etc. assembly, and be because the operating mode that metal bearing uses is limited, very high when being used in rotating speed; At medium be water, slurries, slag is starched or medium has when using under certain condition of severe such as corrosivity, can make its corrosion, and produce very high temperature; Or make its very quick-wearing, inefficacy, and having very big noise when the most important thing is in being used in some precision equipments, to use, wear resistance ratio is more serious; Be metal and intermetallic friction between metal rolling element, metal retainer and the inside and outside circle of bearing during work, because the thermal expansion coefficient of metal is high, so the friction-produced high heat; Make its abrasion very fast, shortened its working life greatly, causing needs frequent the parking to change bearing; The loss that shutdown causes is big, and maintenance cost is high, influences manufacturing efficiency.
Summary of the invention:
Existing bearing wear is fast, working life short and to deficiencies such as the conditional situation of operating mode, the present invention provides a kind of ultra-high molecule composite bearing in order to overcome, and itself has good self lubricity; Wear and tear wash away for a short time, wear-resistant, anti-, corrosion-resistant, noise free, in light weight; Has the good comprehensive performance; Prolonged its working life, at some seawater, panned gold ore out, wash the sand, the liquid medium in the operating mode such as land is all can use under the abominable operating mode such as water, slurries, slag slurry, dust.
The technical solution adopted for the present invention to solve the technical problems is: there are two kinds of forms in the ultra-high molecule composite bearing, and a kind of is ultra-high molecule composition metal bearing, and another kind is a ultra-high molecule composite ceramics bearing; Promptly be inside and outside circle by macromolecular material, the rolling element of pottery or metal material, material is formations such as metal or high molecular retainer; Wherein two of the ultra-high molecule composite bearing kinds of forms are to divide according to the difference of rolling element material, when the rolling element material adopts the industrial ceramics of superhard wear consumption, be mainly used in medium and have under the severe corrosive occasion since ceramic rolling element have wear-resistantly, high temperature resistant, corrosion-resistant, anti-wash away, high intensity and hardness, anti-oxidant, fire prevention, characteristics such as thermal expansion coefficient is little, self lubricity is good; When the rolling element material adopted metal, being mainly used in medium was the occasion of dust, because the metal rolling element both can satisfy some working condition requirements; Practiced thrift its cost again; The ultra-high molecule composite bearing is in when work, oil-free self lubrication, noise free; In light weight; And can alleviate abrasion, the abrasivity of medium greatly to it, reduced because fricative heat reaches and wears and tears purpose little, long service life.
The invention has the beneficial effects as follows: the ultra-high molecule composite bearing can use under very abominable operating mode, reaches the purpose that bearing did not lose efficacy, and work the time can alleviate abrasion, the extent of corrosion of medium to it greatly; Prolonged the working life of ultra-high molecule composite bearing; Oil-free self lubrication during work, and noise free in the course of the work, in light weight; Reduce the cost of use of this type of spare unit spare, improved manufacturing efficiency greatly.

Embodiment:
1. macromolecular material inner rings among the figure, 2. macromolecular material outer ring, 3. ceramic rolling element (also can be metal), 4. macromolecular material retainer (also can be metal).
In Fig. 1, macromolecular material inner ring (1), outer ring (2) are as the skeleton of bearing, and macromolecular material retainer (4) plays well evenly distribution effect to ceramic rolling element (3); Make it keep certain distance in a circumferential direction; Pottery rolling element (3) adopts the fit system in gap with macromolecular material retainer (4) and macromolecular material inner ring (1), outer ring (2), thereby they are relatively rotated, at work noise free; Have well wear-resisting, corrosion-resistant, abrasion resistance; Long service life, and can under very abominable operating mode, use, play the purpose that bearing did not lose efficacy.
In embodiment illustrated in fig. 2, macromolecular material inner ring (1), outer ring (2) are as the support of bearing, and both match.
In the embodiment shown in fig. 3, macromolecular material retainer (4) keeps certain distance in a circumferential direction to ceramic rolling element (3), and both match.
