Abstract
The invention discloses a graphite shaft sleeve, comprising a shaft sleeve body; the inner surface of the shaft sleeve body is provided with a layer of chromium in an electroplating way; a spiral graphite groove is formed at the inner side of the shaft sleeve body; the graphite groove is filled with a small amount of rare earth graphite. The strength of the shaft sleeve is improved by electroplating the chromium, the graphite groove for storing the graphite is formed in the shaft sleeve, and the graphite groove is formed in a spiral way, so that all the area, which is in contact with a shaft, of the shaft sleeve is lubricated by the graphite, the shaft is more stable during work, and the shaft sleeve is not damaged by uneven stress.
Description
Technical field
The present invention relates to a kind of axle sleeve is and in particular to a kind of graphite bushing.
Background technology
Axle sleeve is the tubular machine components being enclosed within rotating shaft, is an ingredient of sliding bearing, axle sleeve is overall knot
Structure, be relative motion between axle and axle sleeve during rotation, and in During Process of Long-term Operation, journal surface is extruded axle sleeve by expansion set
Power and the effect of composite machine power, will lead to its permanent deformation, diameter or reduction.Accordingly, it is desirable to provide a kind of new technology
Scheme is solving the above problems.
Content of the invention
In order to overcome the deficiencies in the prior art, the technical problem to be solved is that design one kind has high intensity height
The graphite bushing of lubrication.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of graphite bushing, including sleeve body, the plating inner surface of described sleeve body has one layer of chromium, described axle
It is provided with spiral helicine graphite cuvette inside set body.
Present invention employs chromium plating to strengthen the intensity of axle sleeve, and be provided with the graphite cuvette depositing graphite, stone in axle sleeve
Ink groove adopts spiral to arrange, and the area that axle sleeve is contacted with axle so can be made all to obtain the lubrication of graphite, make axle operationally more
Stable, axle sleeve is also not forced inequality and damages.
Further, the electroplating thickness of described chromium is 5 microns, thickness too thin can hardness not, hardness too thick stress when hold
Easily burst apart.
Further, described sleeve body, through Overheating Treatment, improves the mechanical performance of material, axle sleeve, eliminates residual stress
With the machinability improving metal.
Further, the sealing two ends of described graphite cuvette, it is to avoid graphite is dished out outside axle sleeve in axle high-speed rotation.
Further, also include graphite, in described graphite cuvette, be filled with graphite, graphite is countershaft to serve lubrication.
Further, it is added with rare earth in described graphite, enhance the toughness of graphite so as to be that axle friction makes to disappear
Consumption.
Further, the content of described rare earth is 0.01～00.02%.
It is an advantage of the current invention that: present invention employs the bulk strength that chromium plating process enhances axle sleeve, in axle sleeve also
It is provided with the spiral graphite cuvette depositing graphite, increased the lubricity of axle；It is added with a small amount of rare earth in graphite, make graphite more
Wear-resisting, more preferably, service life is more long for lubricant effect.
Brief description
A kind of axonometric chart of graphite bushing of Fig. 1 present invention；
A kind of sectional view of graphite bushing of Fig. 2 present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and be embodied as case describe in detail the present invention:
As shown in Figure 1 or 2, a kind of graphite bushing, including the sleeve body 1 through Overheating Treatment, described sleeve body 1
Plating inner surface have one layer 5 microns of chromium, chromium plating enhances the bulk strength of axle sleeve, and in axle high-speed rotation, axle sleeve is in extruding
It is difficult permanent deformation, diameter or reduction in the presence of power and composite machine power；It is provided with spiral inside described sleeve body 1
The graphite cuvette 2 of shape, the helical design of graphite cuvette 2 primarily to making the axle can be with graphite contact in rotation process, then graphite
Lubrication lower axle rotate more stable.
The sealing two ends of described graphite cuvette 2, so can make the thing in graphite cuvette 2 be difficult to dish out, and also will not make outer
The thing on boundary enters in axle sleeve.
Also include graphite 3, be filled with graphite 3 in described graphite cuvette 2, be added with rare earth in ink 3, the content of rare earth is
0.01～00.02%.With the addition of rare earth graphite 3 have more wearability, and then make graphite 3 lubricity more preferable.
Ultimate principle, principal character and the advantages of the present invention of the present invention have been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not limited by examples detailed above, the simply present invention's of description in examples detailed above and description
Principle, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these change and change
Enter to both fall within scope of the claimed invention.
