Abstract
The utility model discloses an ultrahigh molecular weight polyethylene bearing, which mainly comprises an outer ring, a cylindrical ball, a holder, an inner ring and an inner ring separation blade. The bearing is characterized in that an annular groove is formed on the inner sidewall of the outer ring; an annular groove is also formed on the outer sidewall of the inner ring; the holder is arranged between the outer ring and the inner ring, and is in clearance fit with each of the outer ring and the inner ring; a ball hole is formed in the holder; the cylindrical ball is arranged in the ball hole; and each of the outer ring, the inner ring, the inner ring separation blade, the holder and the cylindrical ball is formed by die-pressing and machining an ultrahigh molecular weight polyethylene material. Compared with a metal bearing, the bearing has the advantages that production cost is lowered; a plastic material has a high self-lubricating property, so that the use of a lubricant or lubricating oil is avoided; and the bearing has high corrosion resistance, so that the bearing can be used for all weak acids and alkali as well as a part of strong acids and alkali.
Description
Technical field
The utility model belongs to technical field of polymer materials, a kind of specifically ultra-high molecular weight polyethylene bearing.
Technical background:
Bearing is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.Also we can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.Bearing is for the stability that adopts driven off by shaft machinery, the transmission accuracy, and in working life, each side such as Security and even noise all have important effect, and therefore to improve the research of bearing quality underway always to optimizing bearing performance.
Mostly traditional bearing is the metallic material bearing, and this class bearing is high temperature resistant, and wear resistance is better, but also has several defectives: 1, the metal of labor, and metal price can constantly rise along with the loss day by day of metal; 2, metal bearing must be annotated and reduced the oiling agent of parts friction, and annual consumption is also very big; 3, the chemical property of metal bearing is comparatively active, is prone to oxide etch, for surrounding environment affects.Therefore in the last few years, along with developing rapidly of materials science, adopted the field of nonmetallic material bearing more and more wider.
Summary of the invention
The goal of the invention of the utility model is to overcome the deficiency of existing technology, thereby a kind of have wear-resisting, shock-resistant, corrosion-resistant, selflubricating, a kind of ultra-high molecular weight polyethylene bearing that the absorption impact energy is good are provided.
For realizing above-mentioned purpose; The technological scheme that the utility model adopted is: a kind of ultra-high molecular weight polyethylene bearing, mainly constitute by outer ring, cylinder ball, retainer, inner ring, inner ring catch, and it is characterized in that: the madial wall of described outer ring is provided with annular groove; Also be provided with annular groove on the outer side wall of inner ring; Described retainer places between outer ring and the inner ring, is Spielpassung with outer ring and inner ring, and described retainer is provided with the hole of bead; Described cylinder ball is located in the hole of bead, and described outer ring, inner ring, inner ring catch, retainer, cylinder ball are the superhigh molecular weight polyethylene material mold pressing and process.
Adopt said structure, make the cylindrical bearing ball place in the hole of bead of retainer and in the annular groove of Internal and external cycle, carry out rolling motion, greatly reduce the friction of bearing and the loss of ball; Reduced the heating phenomenon of bearing, reduced heating temperature, in the performance that has guaranteed bearing; Compared to metal bearing, reduced cost of production, and because the self-lubricating property of plastic materials is good; Need not use any oiling agent or lubricant oil, not only maintenance cost reduces, also environmental protection more simultaneously; The bearing that adopts superhigh molecular weight polyethylene material to process; Corrosion resistance is also highly desirable, can in all weak acid alkali, use, and in the part strong acid-base, also can use.

Embodiment
Through description of drawings, the technological scheme of the utility model is done further detailed description below.
As shown in Figure 1, be the preferred version of the utility model, it has shown a kind of ultra-high molecular weight polyethylene bearing; Mainly constitute by outer ring 1, cylinder ball 5, retainer 4, inner ring 2, inner ring catch 3; It is characterized in that: the madial wall of described outer ring 1 is provided with annular groove, also is provided with annular groove on the outer side wall of inner ring 2, and described retainer 4 places between outer ring 1 and the inner ring 2; Be Spielpassung with outer ring 1 and inner ring 2; Described retainer 4 is provided with the hole of bead, and described cylinder ball 5 is located in the hole of bead, and described outer ring 1, inner ring 2, inner ring catch 3, retainer 4, cylinder ball 5 are the superhigh molecular weight polyethylene material mold pressing and process.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equivalent variations and improvement of being done according to the utility model application range are all due within the covering scope of the utility model.
