Abstract

The utility model provides a lubricating sleeve comprising a sleeve main body. The sleeve main body is provided with an inner hole through which a plug-in can pass; and the sleeve main body is provided with a surface coating of tungsten disulfide. The thickness of the surface coating is 0.5-0.7 microns. The sleeve main body is in a cylindrical structure. A flange end part which is overturned outwards is arranged at the tail end of the sleeve main body. According to the lubricating sleeve disclosed by the utility model, a paint-type surface coating is adopted, so that the abrasion between an inner plug-in and the sleeve is reduced and the service life is prolonged by 2-3 times.

Description

A kind of lubricated sleeve
Technical field
The utility model relates to a kind of parts of mould, is specifically related to a kind of lubricated sleeve, belongs to the technical field of mould.
Background technique
Sleeve is the hollow thin-wall spare in revolving parts, is a kind of part common in the machining, in all kinds of machines, uses very extensively, mainly plays supporting or leading role.
Common various forms of race rings and axle sleeve that supporting rotating shaft is arranged; Drill bushing on the anchor clamps and guide sleeve; The valve pocket of the cylinder liner on the internal-combustion engine, the oil hydraulic cylinder in the hydraulic system and electrohydraulic control etc. all belongs to sleeve part.
Abrasion between sleeve plug-in part and the sleeve increases a lot, and application life shortens greatly.
The model utility content
The purpose of the utility model is, a kind of lubricated sleeve is provided, to overcome the above-mentioned shortcoming and defect of existing in prior technology.
The technical problem of the required solution of the utility model, can realize through following technological scheme:
A kind of lubricated sleeve comprises: sleeve body, and the endoporus that plug-in unit passes is held in said sleeve body setting, it is characterized in that, and said sleeve body is provided with the cover coat of tungsten disulfide.
Wherein, the thickness of said cover coat is 0.5～0.7 μ m.
Wherein, the thickness of said cover coat is 0.5 μ m.
Wherein, said sleeve body is set to cylindrical structure.
Further, the end of said sleeve body is provided with to the flange end of turning up.
The beneficial effect of the utility model:
The utility model adopts tungsten disulfide WS 2Cover coat reduce friction factor, reduce wear, interlock etc.Many device maintenance, maintenance issues that minimizing is caused by friction, abrasion etc.
Overcome or reduce the mechanical lubrication problem, improve the working efficiency and the working life of machinery.
Normal loading reaches 100,000PSI (or identical with the bearing capacity of base material).Operating temperature range is wide, from-273 ℃ to 60.50 ℃.
There are not any harmful components, safety and environmental protection.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the another kind of structural representation of the utility model.
Reference character:
Sleeve body 100, flange end 200, endoporus 300, cover coat 400 and plug-in part 500.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples only are used to the utility model is described but not the scope that is used to limit the utility model.
The experimental technique of unreceipted actual conditions in the following example, usually according to normal condition, or the condition that manufacturer provides is carried out.
Embodiment 1
A kind of lubricated sleeve, as shown in Figure 1, comprising: sleeve body 100, sleeve body 100 adopts die steel to process cylindrical structure.Many the matching with frame or box body hole with interference or transition fit of the outer round surface of sleeve body 100 play supporting role.
Sleeve body 100 inside are endoporus 300, and endoporus 300 is to hold plug-in part 500 to pass.Endoporus 300 matches with plug-in part 500, and sleeve body 100 mainly play the guiding role or supporting role, matches with the shape of plug-in part 500, and plug-in part 500 is generally travel axis, main shaft, piston, guiding valve etc.
Sleeve body 100 is provided with the cover coat of tungsten disulfide.The thickness of cover coat is 0.5～0.7 μ m.The preferred thickness of cover coat is 0.5 μ m.
Embodiment 2
A kind of lubricated sleeve, as shown in Figure 2, sleeve body 100 is set to cylindrical structure.Sleeve body 100 inside are endoporus 300.The end of sleeve body 100 is provided with to the flange end of turning up 200.The end face of some sleeve body 100 is the effect that flange end 200 has location or bearing load.All the other are with embodiment 1.
The preparation process and method of the utility model:
Sleeve body 100 is through the ultrasonic cleaning oil removing; With MEVVA source ion injection technique (metal vapor vacuum arc source technology), TiN is attached to the die steel surface subsequently, forms the lubricating film base layer; Layer thickness is 0.005 μ m; On the coating of TiN base, the radio-frequency sputtering mode with in the physical gas phase deposition technology is covered with tungsten disulfide WS then 2Coating, layer thickness are 0.5 μ m.The die steel of the lubricated composite bed of the band that obtains has the characteristic of TiN hardness height and favorable anti-corrosion effect; With tungsten disulfide WS 2Low coefficient of friction, greasy property is high, resistant to elevated temperatures comprehensive function.Be applicable to the surface treatment and the processing and fabricating of various moulds, mechanical part, auto parts and components.
Adopt cover coat (tungsten disulfide WS 2) to the surface treatment treatment technology of sleeve body 100, effectively improved the high temperature of product and prevented killing performance, and then prolonged the working life of product.
Adopt tungsten disulfide WS 2The surface treatment treatment technology carries out WS with sleeve body 100 2Handle, prolonged the working life of product.
Tungsten disulfide WS 2Why show good lubricating property and be because: WS 2Crystal has stratiform structure, layer with layer between combination force a little less than, shear easily, slippage, show as low friction coefficient; WS 2Structural stability shows as good resistance high temperature, resistance to extreme pressure ability; Even be higher than under 400 ℃ the temperature environment WS 2Also can form fine and close tungsten oxide (WO through eremacarsis 3) protective layer, suppress WS 2Further oxidation, and tungsten oxide has very low friction factor equally, still can play the effect that the protective money metal surface does not glue together.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
