In sliding supporting structure for light indusqtry machineries such as medical treatment and food.However, opposing metallic material, the intensity of selflubricatingpiston
It is low low with thermal conductivity, cause yielding, the easy heating in rotation support.Because low intensity, plastic substrate is deformed in equipment operation
Abrasion is caused to aggravate, meanwhile, the heat produced between axle and axle sleeve can not be distributed in time, so that the axle sleeve life-span is low, equipment
Easily break down.
Opposed plastic material, metal material such as copper, aluminium and its alloy, with higher intensity and thermal conductivity.Integrated application
Plastics and the respective feature performance benefit of metal, by the Shooting Technique of the embedded metal material in plastic substrate, manufacture composite construction,
So that the rubbing surface of axle sleeve be plastic material, metal material strengthen rigidity and heat conduction in axle sleeve matrix, can solve it is current from
The shortcoming of lubricating plastic sleeve low intensity poor heat conductivity.
The content of the invention
The purpose of this utility model is to provide a kind of selflubricatingpiston sliding shaft sleeve containing metallic framework, the utility model
Axle sleeve structure is compact, easily manufactured, can solve the problem that the selflubricatingpiston sliding shaft sleeve support strength of all-plastic matrix is low, thermal conductivity
The shortcoming of energy difference.
The utility model solves the technical scheme that its above mentioned problem used：A kind of selflubricatingpiston containing metallic framework
Sliding shaft sleeve is made up of plastic substrate and the metallic framework piece of multiple insertions, by Shooting Technique by plastic substrate and multiple metals
Matrix tablet is combined with each other, wherein, the plastic substrate by the good plastics polytetrafluoroethylene (PTFE) of self-lubricating property, polyimides or
Polyether-ether-ketone is made, and the metallic framework piece is made up of the preferable metal material of copper of heat conductivility, aluminium and its alloy；The metal
Matrix tablet is tooth-shape structure, tooth number Z optional 6,8,10,12, and the inner cylinder face radius R2 of metallic framework piece is more than plastic substrate
Inner cylinder face radius R1, the radius of addendum R3 of metallic framework piece is equal with the external diameter R4 of plastic substrate.It is described two neighboring
Axially spaced-apart between metallic framework piece is equal, and two tooth forms of two neighboring metallic framework piece radially differ half of between cog phase
Angle θ, between cog phase angle θ=360 °/Z.The sliding shaft sleeve uses plastic substrate so that sliding friction surface has coefficient of friction
The advantages of small, self-lubricating, cleaning；Meanwhile, the tooth top surface of the metallic framework piece exposed on axle sleeve outer cylinder and outside rotation branch
The support base contact of support, preferably can spread out of the heat that internal friction be produced, selflubricatingpiston sliding shaft sleeve is led on the whole
Hot property strengthens.In injection manufacturing process, it is desirable between two adjacent metallic framework pieces, interval is equidistant, and differs half
Between cog phase angle θ, be so conducive to mold cavity during injection fill type mobility, it is each uniform to uniformity and axle sleeve equal strength
Property.
The utility model has advantages below compared with prior art：The invention solves existing plastic slide axle sleeve support
The shortcoming of low intensity, heat conductivility difference.By the way that metallic steel matrix tablet and plastic substrate are combined with each other, rigidity is made it have
The advantages of high, intensity is high, thermal conductivity is good, anticorrosive, wearability is good.

Specific embodiment
Embodiment
As shown in figure 1, being the selflubricatingpiston sliding shaft sleeve containing metallic framework disclosed in the utility model, plastic substrate 1
It is combined with each other with multi-disc metallic framework piece 2 by Shooting Technique, wherein, metallic framework piece 2 is by the preferable metal material of thermal conductivity
Expect copper into；Plastic substrate 1 is made up of the good plastic material polytetrafluoroethylene (PTFE) of self-lubricating property.As shown in Fig. 2 metallic framework piece
2 inner cylinder face radius R2 is 35mm, and the inner cylinder face radius R1 of plastic substrate 1 is 30mm, the inner cylinder face of metallic framework piece 2
