Abstract

The utility model relates to the field of bearings, in particular to a plastic bearing. The demand for a light weight is satisfied by the fact that parts of metal materials are replaced by plastic materials, and the demand for performance under the assembling environment of the plastic bearing is satisfied. The technical scheme is that the plastic bearing is formed by the fact that a bearing cap, an outer ring, a holder, an inner ring and a bearing ball are assembled, wherein the outer ring, the holder, the inner ring and the bearing ball are placed inside the bearing cap. The outer side wall of the outer ring is provided with a ring-shaped groove, the outer ring is fixedly embedded inside the bearing cap through the ring-shaped groove, the inner ring is embedded inside the holder, and the holder and the inner ring are in clearance fit. The holder is provided with a ball hole, the bearing ball is arranged inside the ball hole, and the bearing cap, the outer ring, the holder and the inner ring are all made of high-performance engineering plastics. The plastic bearing guarantees bearing performance, and meanwhile greatly lowers production cost compared with a metal bearing.

Description

A kind of plastic bearing
Technical field
The utility model relates to field of bearings, is specifically related to a kind of plastic bearing.
Background technique
Bearing (" Bearing ") is to work the parts of fixing and reducing the load friction factor in mechanical transmission course.Also 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.
Traditional bearing mostly is metallic material and makes, the bearing that adopts metallic material to make, and high temperature resistant, wear resistance is all better, but metal bearing exists following defective:
At first, metal bearing need to expend a large amount of metals, because bearing is the common part in the machinery, annual use amount is very huge, all adopt metallic material to carry out processing and fabricating, can cause seriously expending of metallic material, today this problem day by day soaring in metal price is just particularly outstanding.
Secondly; metal bearing in use must be lubricated, and the oiling agent of namely annotating in metal bearing is with the friction between ball and bearing body in the minimizing bearing; use a large amount of oiling agents not only to consume in the annual industry huge, also environmental protection has been produced serious threat simultaneously.
The 3rd, although metal bearing has high temperature resistant and anti abrasive advantage, the chemical property of metallic material is usually comparatively active, and the corrosion of chemical formulation in use easily occurs the bearing that adopts metallic material to make, and causes bearing deformation and damage.
Whole metal bearing exists processing cost high, needs to add a large amount of oiling agents in the use, easily by the defective of chemical corrosion, therefore in the last few years, along with developing rapidly of materials science, adopts the research of the bearing of nonmetallic material also to obtain fast development.
The model utility content
The purpose of this utility model provides a kind of plastic bearing, reaches light-weighted demand with the part metals material in the plastic materials alternative metals bearing, and has satisfied the performance requirement under its assembly environment.
The technical solution of the utility model is for providing a kind of plastic bearing, described plastic bearing is by bearing cap and outer ring in the inner, position, retainer, inner ring and bearing ball constitute, the outer side wall of described outer ring is provided with annular groove, described outer ring fixedly is nested in the described bearing cap by described annular groove, described inner ring is nested in the described retainer, be Spielpassung between described retainer and the described inner ring, described retainer is provided with the hole of bead, bearing ball is located in the described hole of bead, described bearing cap, the outer ring, retainer, inner ring all adopts high performance engineering plastics to make.
As an improvement of the present utility model, described high performance engineering plastics is nylon 66.
As an improvement of the present utility model, the outer wall of described inner ring is provided with annular groove.
As an improvement of the present utility model, described bearing ball is spheroid, the diameter of described bearing ball matches with cross section, described hole of bead diameter of a circle, being fixedly connected with of the scrolling realization that is positioned at the annular groove on the inner ring outer wall and described retainer, the sphere of described bearing ball all contacts with the internal face of described annular groove and outer ring described inner ring by described bearing ball.
As an improvement of the present utility model, described outer ring, retainer, inner ring adopts the mode of integral molded plastic to be processed into.
The beneficial effects of the utility model are: the utility model adopts plastic materials to make, when having guaranteed bearing performance, compared to metal bearing, greatly reduce cost of production, and because the self-lubricating property of plastic materials is better, reduced the consumption of oiling agent in using, not only reduced cost of use, simultaneously also more environmental protection, the bearing that adopts high polymer plastic to make, corrosion resistance are also comparatively desirable.Plastic bearing reaches light-weighted demand with the part metals material in the plastic materials alternative metals bearing, and has satisfied the performance requirement under its assembly environment.
Description of drawings
