Abstract
The present invention relates to a kind of selflubricatingpiston sliding shaft sleeve containing metallic framework.Described axle sleeve is composited by injection with multiple metallic framework sheets (2) by plastic substrate (1), and wherein, metallic framework sheet (2) is made up of the copper of good heat conductivity, aluminum and alloy material thereof；Plastic substrate (1) is made up of politef, polyimides and the poly ether ether ketone plastic material that self-lubricating property is good.In injection composite manufacturing technology, the axially spaced-apart between described adjacent two metallic framework sheets (2) is equal, two profiles of tooth of adjacent two metallic framework sheets (2) radially half between cog phase angle θ of difference.The present invention solves the shortcoming that existing plastic slide axle sleeve support strength is low, heat conductivility is poor, owing to using metallic framework sheet (2) and the composite construction of plastic substrate (1) so that it is be provided with that rigidity is high, heat conductivity is good, coefficient of friction is little, the advantage such as self-lubricating and cleaning.
Description
Technical field
The present invention relates to a kind of mechanical transmission part technical field, particularly relate to a kind of self-lubricating containing metallic framework and mould
Material sliding shaft sleeve.
Background technology
Selflubricatingpiston sliding shaft sleeve, opposing metallic sliding bearing, have that compact conformation, coefficient of friction be little, self-lubricating is exempted from
Safeguard, corrosion-resistant, absorbing, the advantage such as wear-resisting.The most on-stream do not have abrasive dust, has sanitation and hygiene feature, and therefore, it is extensive
In the sliding supporting structure of the light indusqtry machineries such as medical treatment and food.But, opposing metallic material, the intensity of selflubricatingpiston
Low low with heat conductivity, cause rotate support in yielding, easily heat up.Because intensity is low, plastic substrate deformation in equipment operation
Causing abrasion aggravation, meanwhile, the heat produced between axle and axle sleeve can not distribute in time, so that the axle sleeve life-span is low, and equipment
Easily break down.
Opposed plastic material, metal material such as copper, aluminum and alloy thereof, there is higher intensity and heat conductivity.Integrated application
Plastics and the respective feature performance benefit of metal, by embedding the Shooting Technique of metal material in plastic substrate, manufacture composite construction,
The rubbing surface making axle sleeve is plastic material, and metal material strengthens rigidity and heat conduction in axle sleeve matrix, can solve current from
The shortcoming of the low poor heat conductivity of lubricating plastic sleeve intensity.
Summary of the invention
It is an object of the invention to provide a kind of selflubricatingpiston sliding shaft sleeve containing metallic framework, this invention axle sleeve structure
Compact, easily manufactured, it is possible to solve all-plastic matrix selflubricatingpiston sliding shaft sleeve support strength is low, heat conductivility is poor lacks
Point.
The present invention solves its problems referred to above and be the technical scheme is that a kind of selflubricatingpiston containing metallic framework slides
Axle sleeve is made up of the metallic framework sheet of plastic substrate with multiple embeddings, by Shooting Technique by plastic substrate and multiple metallic frameworks
Sheet is combined with each other, and wherein, described plastic substrate is by good plastics politef, polyimides or the polyethers of self-lubricating property
Ether ketone is made, and described metallic framework sheet is made up of the preferable metal material of copper of heat conductivility, aluminum and alloy thereof；Described metallic framework
Sheet is tooth-shape structure, optional 6,8,10,12 of tooth number Z, and the inner cylinder face radius R2 of metallic framework sheet is interior more than plastic substrate
Face of cylinder radius R1, radius of addendum R3 of metallic framework sheet is equal with the external diameter R4 of plastic substrate.Described adjacent two metals
Axially spaced-apart between matrix tablet is equal, two profiles of tooth of adjacent two metallic framework sheets radially half between cog phase angle θ of difference,
Between cog phase angle θ=360 °/Z.Described sliding shaft sleeve uses plastic substrate so that it is little, certainly that sliding friction surface has coefficient of friction
The advantages such as lubrication, cleaning；Meanwhile, the tooth top surface of metallic framework sheet axle sleeve outer cylinder exposed and rotatably supported of outside
Support seated connection touches, and can preferably the heat that internal friction produces be spread out of, the heat conductivility of selflubricatingpiston sliding shaft sleeve on the whole
Strengthen.In injection manufacturing process, it is desirable between two adjacent metallic framework sheets, interval is equidistant, and differs half between cog phase
Parallactic angle θ, when being so conducive to being molded, mold cavity fills type mobility, respectively to uniformity and axle sleeve equal strength uniformity.
The present invention compared with prior art has the advantage that this invention solves existing plastic slide axle sleeve support strength
The shortcoming that low, heat conductivility is poor.By metallic steel matrix tablet is combined with each other with plastic substrate so that it is there is rigidity high, strong
The advantages such as degree is high, heat conductivity is good, anticorrosive, wearability is good.

Specific embodiments
Embodiment
As it is shown in figure 1, be the selflubricatingpiston sliding shaft sleeve containing metallic framework disclosed by the invention, plastic substrate 1 is with many
Sheet metallic framework sheet 2 is combined with each other by Shooting Technique, and wherein, metallic framework sheet 2 is by the preferable metal material of copper of heat conductivity
Make；Plastic substrate 1 is made up of self-lubricating property good plastic material politef.As in figure 2 it is shown, metallic framework sheet 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 sheet 2 half
Footpath R2 is more than the inner cylinder face radius R1 of plastic substrate 1, and the material so making sliding contact is all plastic substrate 1, thus protects
Hold sanitation and hygiene, reduce coefficient of friction, improve self-lubricating capacities.As it is shown on figure 3, radius of addendum R3 of metallic framework sheet 2 with
The external diameter R4 of plastic substrate 1 is equal equal to 50mm, this ensure that the metallic framework sheet 2 tooth top table exposed on axle sleeve outer cylinder 11
Face 21, supports seated connection with installation in use and touches, and preferably the heat that internal friction produces can be spread out of, improve leading of axle sleeve
Hot.As shown in Figure 4, metallic framework sheet 2 has tooth-shape structure 22, optional 8 of tooth number Z, every adjacent two panels metallic framework sheet 2 institute
It is θ that the position placed differs half between cog phase angle, between cog phase angle θ=60 °, plastic melting when its purpose is to improve injection
The mobility of body, so that melt is easier to be full of die cavity.
