Description
Technical field
The present invention relates to field of material technology more particularly to a kind of adaptive surface texture for the pair that rubs.
Background technique
In mechanical system, friction, abrasion and the greasy property between the friction pair of each relative motion are to mechanical system
Performance, efficiency and service life etc. have direct influence.According to statistics, there are about 30~50% to be consumed in for the energy used in the world
Friction, and abrasion caused by rubbing is the main reason for mechanical equipment fails.A series of tribology theories and experimental studies results
Show: appropriate Surface Texture (surface microscopic feature) can improve the lubricant effect in friction process.Surface Texture is as one
The important improvement lubrication of kind, the means for reducing friction, are given more sustained attention by researcher.
Surface Texture, which refers to, to be processed on friction surface using specific processing method with certain size and arrangement
The shape type of micro- geometrical characteristic array, Surface Texture is more, mainly includes the shapes such as pit and groove.Common processing method
There is micro-cutting processing, grinding, abradant jet processing, laser processing, electrical discharge machining, LIGA technology, UV photoetching technique, anti-
Answer ion etching, Ultrasonic machining, shot blasting on surface processing and surface pressure lithography etc., wherein application it is most be laser processing, electricity
Spark processing, Electrolyzed Processing and LIGA technology.
In fact, and not all Surface Texture can play the role of reduce friction, only carry out reasonable surface and knit
Structure design just can make it play due effect.For specific operation design particular surface texture can reduce energy loss and
Increase the secondary service life of friction, to energy saving, protection environment and the ecological balance is promoted to have great importance.However, real
In the application of border, engineering friction is secondary to be usually in different lubricating status, for the design of a certain lubricating status surface texture characteristic such as
Fruit works in other lubricating status, and tribological property may decline to a great extent.
Traditional Surface Texture technology is exactly to utilize physics, method chemically or mechanically artificially at surface of friction pair processing
By micro- texture of certain regular distribution.Texture has fixed geometrical characteristic slightly for this, is only capable of making engineering friction pair in a certain work
Optimal working performance is obtained under the conditions of condition.It is usually under changeable working condition however, engineering friction is secondary, has fixation several
Micro- texture of what feature does not ensure that engineering friction pair total energy under various working conditions obtains preferable tribological property.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of for the secondary adaptive surface texture that rubs, this surface is knitted
Structure can change its texture parameter according to the working condition of engineering friction pair, keep engineering friction secondary always in its optimal work
Within the scope of, it is ensured that friction pair all has good tribological property under different working conditions.
In order to solve the above technical problems, the present invention is used to rub, secondary adaptive surface texture includes friction copy body, institute
It states the secondary body surface of friction and is machined with micro- texture characteristic shape, further include texture coating, the texture coating is set to described
It rubs and secondary body surface and is in close contact with micro- texture characteristic shape.
Further, micro- texture characteristic shape includes pit or groove, and uses honing technique, laser surface texture
Change processing technology, reactive ion etching technology, pressure lithography, shot blasting on surface processing technique, ultrasonic impact processing technology or photoetching
Electrochemical micromachining technology is machined in the secondary body surface of the friction.
Further, the texture coating processes micro- texture characteristic in the secondary body surface that rubs using spraying process
In shape, the coefficient of friction and elasticity modulus of the texture coating are less than the coefficient of friction and elasticity modulus of friction copy body.
Further, the texture coating is the unevenness that the secondary body surface that rubs is arranged in array.
Since the present invention uses above-mentioned technical proposal for the secondary adaptive surface texture that rubs, i.e. this Surface Texture includes rubbing
Copy body is wiped, it further includes texture coating that the secondary body surface of the friction, which is machined with micro- texture characteristic shape, the texture covering
Layer is set to the secondary body surface of the friction and is in close contact with micro- texture characteristic shape.This Surface Texture can be according to work
The secondary working condition of journey friction, changes its texture parameter, makes engineering friction is secondary to be within its optimal working range always, it is ensured that
Friction pair all has good tribological property under different working conditions.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is the present invention for the secondary adaptive surface texture schematic diagram that rubs；
Fig. 2 deforms schematic diagram for the Surface Texture after friction pair is loaded in this Surface Texture.
Specific embodiment
As shown in Figure 1, the present invention is used to rub, secondary adaptive surface texture includes friction copy body 1 to embodiment, described
Friction 1 surface of copy body is machined with micro- texture characteristic shape 11, further includes texture coating 2, and the texture coating 2 is set to institute
It states friction 1 surface of copy body and is in close contact with micro- texture characteristic shape 11.
Preferably, micro- texture characteristic shape 11 includes pit or groove, and is knitted using honing technique, laser surface
Structure processing technology, reactive ion etching technology, pressure lithography, shot blasting on surface processing technique, ultrasonic impact processing technology or light
It carves electrochemical micromachining technology and is machined in 1 surface of friction copy body.
Preferably, the texture coating 2 processes micro- texture spy on friction 1 surface of copy body using spraying process
It levies in shape 11, the coefficient of friction and elasticity modulus of the texture coating 2 are less than the coefficient of friction and elasticity of friction copy body 1
Modulus.
Preferably, the texture coating 2 is the unevenness that friction 1 surface of copy body is arranged in array.
As shown in Fig. 2, this adaptive surface texture, which uses, to be had compared with low-friction coefficient and covers compared with the texture of low elastic modulus
Cap rock 2 be covered in friction copy body 1 micro- texture characteristic shape 11 in, when friction vice division chief when light duty, texture coating 2
Lesser flexible deformation 13 only occurs, makes micro- texture characteristic of 1 surface of copy body with smaller depth that rub；When friction vice division chief in
In/severe duty when, biggish flexible deformation 13 will occur for texture coating 2, make rub 1 surface of copy body have larger depth
Micro- texture characteristic.When the elasticity modulus of 2 material of texture coating and coefficient of friction choose suitable, it will make have this adaptive
