Description
Technical field
Texture is lubricated the present invention relates to a kind of reticulated elastomeric adaptive surface.
Background technology
With the development of three generations's nuclear power, carrier-borne nuclear power and catapult technique, key equipment friction pair is situated between without high-tension lubrication
Under matter jack-up state or hot transient state, still possess relatively low abrasion and preferable lubricating status.Rotate or slide unit typically has two
Quasi-tradition friction pair, metal class such as babbit, non-metal kind such as graphite or resin；Babbit is used for oil lubrication, and graphite is used
In water lubrication, resin, which can be used to oil lubrication, can be used for water lubrication；When without high-tension lubrication medium jack-up, friction pair is low
Fast oil film or moisture film are relatively low, and this boundary lubrication can not be effectively isolated friction pair and directly contact, surface of friction pair will cause compared with
Big abrasion is damaged, or even causes to peel off.It is therefore desirable to solve the problems, such as excessive wear under boundary lubrication condition.
Tradition, which improves boundary lubrication, two methods, the first, increase friction lubricating medium turnover both sides depth；Second
Kind, increase microcosmic texture (such as circular, rectangle pit) in surface of friction pair.First method can cause friction pair in
During boundary lubrication, increase the quantity delivered of lubricant medium, though boundary lubrication can be improved to a certain degree, result in stable state lubricant medium
Pressure curve peak value is too high, when depth is excessive, and the further increased wear of negative pressure occurs in medium outflow side.Second method can make
Friction pair is obtained under boundary lubrication condition, surface of friction pair is still distributed more lubricant medium pit, but these pits will
Lubricant medium reduces the bearing capacity of friction pair, although improve boundary lubrication in the pressure distribution of friction pair during influence stable state
The abrasion problems of too of state, but friction pair performance when reducing stable state.
Accordingly, it would be desirable to develop a kind of new construction, this Surface Texture can be automatically raised in hot transient state or low speed, but
It is again automatic during stable state to disappear；Excessive wear when can improve boundary lubrication, and friction pair bearing capacity, surface when not influenceing stable state
Texture can dynamic generation.
The content of the invention
Excessive wear problem, no-load when can improve low speed boundary lubrication and dry friction it is an object of the invention to provide one kind
Or the lubricant medium of friction pair sets up fluid lubrication again during high speed, netted lattice texture disappears automatically, does not influence friction pair steady
The automatic raised reticulated elastomeric adaptive surface that returns of state load-carrying properties lubricates texture.The technical scheme is that：It is a kind of netted
Elastic adaptive surface lubricates texture, and the upper surface of base material 2 sets groove 3, and coating 1 is arranged in the top of base material 2, coating 1
Divide embedded groove 3, gapless keeps superficial layer 6 and rigid body above close connection, coating 1 straight between coating 1 and base material 2
Connect contact portion raised, bossing 16 is the corresponding surface superficial layer 6 of groove 3, the non-upper strata of bossing 7 retains lubrication and is situated between
Matter 17, second thickness 5 is 0.5 with the ratio of first thickness 4：5.
The rectangular distribution in the groove 3 of base material 2 of the netted lattice 19 of the first kind, groove 3 of the netted lattice 20 of Equations of The Second Kind in base material 2
Inside assume diamond in shape distribution, and the netted lattice 21 of the 3rd class are in fan-shaped distribution in the groove 3 of base material 2, and the netted lattice 22 of the 4th class are in base material 2
It is distributed in a ring in groove 3, the netted lattice 23 of the 5th class are in the groove 3 of base material 2 in scroll distribution.
Friction pair is moving part and static part, when moving part is in low-speed run state or in quick acceleration and deceleration
The continuous thickness of lubricant medium above transient behaviour, static part will be reduced, and after friction pair is directly contacted, groove 3 is corresponding
Surface superficial layer 6 will be raised, and bossing 16 is general to be higher by 1 micron to 30 microns than non-bossing 7, forms multiple storages
Friction pair dry friction face can be greatly lowered in the lubricant medium 17 deposited in the equivalent shallow-water tank of lubricant medium 17, equivalent shallow-water tank
Product, and the space of partial hydrodynamic lubrication is provided, it is helpful for excessive wear when improving friction pair boundary lubrication；Rub sidestream
Body lubrication is re-established, and after the direct contact lost of friction pair, the automatic fall-back of bossing 16, superficial layer 6 recovers normal, do not influenceed
Friction pair stable state bearing capacity.Second thickness 5 and the ratio of first thickness 4 are if less than 0.5 times, when the direct contact of friction pair disappears,
The height of projection of bossing 16 will be less than 1 micron, it is impossible to play a part of improving boundary lubrication；Second thickness 5 and first
The ratio of thickness 4 is if greater than 5 times, and the height of projection of bossing 16 will be much larger than 10 microns, it will the increase planted agent of coating 1
Power, and boundary lubrication effect is reduced, the thickness amounts level of lubricant medium fluid film during beyond boundary lubrication.
The netted lattice self-lubricating surface texture of the present invention, with first kind increase friction lubricating medium turnover both sides depth tradition
Improve boundary lubrication method to compare, you can in friction pair boundary lubrication condition lower convexity network structure, can be with inside network structure
Micron order lubricant medium composite lubricating film is deposited, boundary lubrication dry friction can be improved, is set up when separating fluid lubrication between friction pair,
Raised network structure falls after rise, bearing capacity when not interfering with stable state so, will not occur what such as outlet edge negative pressure problem was produced
Excessive wear.Compared with Equations of The Second Kind increases the pit tradition improvement boundary lubrication method that surface can not change, you can in friction pair
Micron order lubricant medium composite lubricating film can be deposited inside boundary lubrication condition lower convexity network structure, network structure, can be improved
Boundary lubrication dry friction, sets up, raised network structure is fallen after rise, and stable state is not interfered with so when separating fluid lubrication between friction pair
When bearing capacity, will not occur such as traditional type surface crater reduces the weakness of stable state bearing capacity.
The netted lattice self-lubricating surface texture of the present invention have passed through certain water lubricating thrust bearing bench test checking, without high pressure
Under the operating mode of water jack-up, multiple start and stop and dead electricity running down experiment are have passed through, through tearing machine check open, thrust tile-base surface finds that netted lattice rub
Scratch mark, illustrates that thrust tile-base surface is improved by netted lattice self-lubricating surface texture, can improve boundary lubrication excessive wear.
