Description
Technical Field
The application relates to the technical field of mechanical auxiliary tribology characteristics, in particular to a surface lubrication texture, a compressor part, a compressor and an air conditioner.
Background
In the long-time operation process of the compressor, wear forms such as abrasive particles, adhesion, fatigue and the like often occur on the surface of a friction pair of a key part, and the long service life and stable operation of the compressor are seriously influenced. In order to solve the problem of friction and wear of the surface of the friction pair, the traditional tribology theory considers that the smoother the surface of the friction pair is generally, and the better the friction performance is, and the theoretical research and engineering practice in recent years also show that the smoother the surface of the friction pair is, the better the surface roughness is, the better the lubricating oil film is formed, so that the friction and wear are reduced. A series of micro texture textures with different sizes, depths, area ratios and arrangement modes are properly processed on the surface of the motion friction pair, the effects of storing lubricating oil and impurity particles can be achieved, the fluid film bearing capacity is improved through the dynamic pressure effect of the textures, the end face lubrication state is improved, and the tribology performance is improved. However, under the influence of the change of working condition parameters, especially under the conditions of low rotating speed and high load, the dynamic pressure effect of the texture is not enough to maintain stable fluid lubrication, and the long-time friction action can cause the oil storage in the texture to be carried and extruded and discharged out of a lubrication area, so that the oil storage in the texture is rapidly reduced, the friction surface is forced to be in a boundary lubrication and mixed lubrication state after running for a period of time, and the problems of increased friction coefficient, serious abrasion and the like occur.
In order to solve the problem, various solutions have been proposed in the prior art, which focus on improving the hydrodynamic pressure performance from the pattern design direction, and require an external oil supply system to continuously provide lubricating oil to maintain the end face fluid lubrication state, and the texture itself cannot achieve the purpose of long-term oil storage, resulting in the problems of complex auxiliary system, severe lubricating oil consumption, and the like. When the external disturbance causes the change of the operating condition, particularly under the conditions of low rotating speed and high load, the dynamic pressure effect of the texture is weak, the oil quantity of a lubricating gap is insufficient, the long-time friction action easily causes the oil storage in the texture to be carried and extruded to be discharged from the lubricating area, the friction surface is forced to be in the states of boundary lubrication, mixed lubrication and the like, and the phenomena of friction and abrasion and the like are further caused.
Therefore, the existing texture can not meet the requirements of long-term oil storage and return functions while providing sufficient hydrodynamic pressure effect, and cannot ensure reliable and stable operation and long service life of a friction pair.

Detailed Description
Referring to fig. 1 to 6 in combination, according to an embodiment of the present application, the surface lubrication texture includes a dynamic pressure lubrication surface 1, a hole structure is disposed on the dynamic pressure lubrication surface 1, the hole structure is arranged along a fluid flow direction, the hole structure includes a first hole 2 and a second hole 3, the first hole 2 and the second hole 3 are arranged at intervals, and a hole depth of the first hole 2 is smaller than a hole depth of the second hole 3. The surface lubrication texture is applied to lubrication between lubrication surfaces of friction pairs and is used for improving the lubrication effect between the friction pairs.
By forming the first hole 2 and the second hole 3 with different depths on the dynamic pressure lubrication surface 1, the first hole 2 with smaller hole depth can be used for providing sufficient dynamic pressure effect on the dynamic pressure lubrication surface 1, and the fluid film bearing capacity is improved; meanwhile, the second hole 3 with the deeper hole depth can be utilized, so that when a fluid medium flows out under the action of inertia or centrifugation, a negative pressure cavity is generated at the bottom of the deep hole, a pressure difference action opposite to the flowing direction of the fluid medium is formed between the fluid medium and an end surface lubricating oil film, lubricating oil is forced to flow back, the purpose of oil storage is achieved, and the long-term oil storage and return function is met.
In the present embodiment, the first hole 2 is a micro hole having a diameter smaller than 1mm, and the second hole 3 is a deep hole having a depth larger than that of the first hole 2.
The fluid dynamic pressure opening force provided by the matching of the micropores and the deep holes promotes the rapid separation of the matching surfaces, forms fluid lubrication, ensures a non-contact operation state and avoids friction and abrasion. The second hole 3 adopts a deep hole structure, can contain abrasive dust or foreign particles, and prevents the continuous abrasion of abrasive particles. The second hole 3 can also store lubricating liquid, and the stored lubricating liquid can be extruded, carried or permeated to a matching surface along with shearing motion, so that a secondary lubricating effect is achieved.
Referring to fig. 1 to 4 in combination, according to the first embodiment of the present application, the first holes 2 are perpendicular to the hydrodynamic lubrication surface 1, and the second holes 3 are inclined with respect to the hydrodynamic lubrication surface 1.
In this embodiment, first hole 2 is a micropore, second hole 3 is an inclined hole, micropore and inclined hole are densely arranged on dynamic pressure lubricated surface 1, thereby can all can realize the cooperation of micropore and deep hole in dynamic pressure lubricated surface 1's different positions department, simultaneously, because the deep hole is the inclined hole, consequently when fluid medium fluid flow direction matches with the incline direction of inclined hole, under the fluid flow effect, the outflow resistance of the lubricating oil of storing in the inclined hole is littleer, flow outside the inclined hole along the inclined plane of inclined hole more easily, thereby it forms lubricated fluid film on dynamic pressure lubricated surface 1 to be more convenient, the inclined hole bottom forms the negative pressure cavity because of the medium outflow simultaneously, can reach the purpose of oil storage oil return.
Preferably, the hole depth of the first hole 2 is 1-50 μm, which can make the depth of the first hole 2 shallower, thereby ensuring that the fluid medium can flow into the texture lubrication area along the clearance channel of the friction pair, and accumulate in the first hole 2, generating a significant dynamic pressure effect.
Preferably, the first pores 2 have a pore diameter of 10 to 1000. mu.m.
The first hole 2 can be a cylindrical hole or a variable cross-section hole, for example, the cross-sectional area of the first hole 2 decreases progressively along the direction away from the dynamic pressure lubricating surface 1, so that a groove with a smaller lower part and a larger upper part is formed, the fluid medium can enter and flow out of the first hole 2 more conveniently, the fluid fluidity is improved, and the hydrodynamic effect is improved.
In the present embodiment, the second holes 3 have a hole depth of 0.1 to 1mm, and the ratio of the hole depth to the hole diameter of the second holes 3 is 1 to 10. Through the hole depth and the aperture ratio of injecing second hole 3, can rationally set up the aperture according to the hole depth of second hole 3, form negative pressure effect at fluid medium flow in-process to guarantee the oil storage oil return effect of second hole 3. The dynamic pressure lubrication surface 1 of the texture utilizes the negative pressure effect of the inclined deep hole to achieve the effect of oil storage and oil return on the end surface, and simultaneously utilizes the dynamic pressure effect of the micropores and the damping effect of the deep hole to improve the bearing capacity of a fluid film and maintain the surface fluid lubrication state of a friction pair, thereby achieving the purpose of fluid dynamic pressure lubrication.
The second holes 3 are inclined at an angle theta of 10 DEG to 80 DEG with respect to the hydrodynamic lubrication surface 1. Preferably, the inclination angle θ is 30 ° to 60 °.
In the present embodiment, the second hole 3 is inclined in the direction opposite to the fluid flow direction in the direction away from the dynamic pressure lubrication surface 1. Referring to fig. 2, under the shearing action during the movement of the friction pair, the fluid medium flows along the clearance channel of the friction pair to enter the texture lubrication area, and at the convergence side of the micropores, the fluid is enriched and accumulated, so that a significant dynamic pressure effect is generated. On one hand, in the deep hole, in the direction far away from the dynamic pressure lubricating surface 1, the fluid movement direction is opposite to the texture inclination direction, fluid flows out of the hole area along the inclined surface of the deep hole, a lubricating fluid film is formed on the end face, a negative pressure cavity is formed at the bottom of the deep hole due to the outflow of a medium, the pressure difference force in the direction opposite to the fluid movement is formed under the action of the fluid film pressure of the end face and the negative pressure of the cavity, the negative pressure effect of the cavity is gradually enhanced along with the continuous outflow of the medium out of the deep hole, and when the pressure difference force is greater than the shearing force, the fluid.
The cross-sectional shape of the first holes 2 and/or the second holes 3 is circular, oval, triangular, diamond-shaped, square or rectangular. Generally speaking, the cross-sectional shapes of the holes are selected differently according to the application environments of the friction pair, and a circular hole structure may be preferred for the friction pair moving at high speed, and a diamond hole structure may be preferred for the friction pair moving at low speed. For the friction pairs applied to various different rotating speed working conditions, hole structures in various different shapes can be mixed according to requirements, so that the surface lubricating texture has good adaptability under various rotating speed working conditions, the adaptability of the surface lubricating texture is effectively improved, and the dynamic pressure lubricating effect and performance are improved.
In one embodiment, the first holes 2 are plural, and at least two of the first holes 2 have different cross-sectional shapes.
In another embodiment, the second holes 3 are plural, and the cross-sectional shapes of at least two of the second holes 3 are different.
Preferably, the first holes 2 and the second holes 3 are both plural, and the first holes 2 and the second holes 3 are alternately arranged along the fluid flowing direction. The staggered arrangement means that each row of hole structures comprises first holes 2 and second holes 3, and the first holes 2 and the second holes 3 are staggered and spaced along the fluid flowing direction.
In another embodiment, the first holes 2 and the second holes 3 are arranged in parallel and spaced apart. The parallel interval arrangement here means that along the flowing direction of fluid, one row of pore structures is first hole 2, and another row of pore structures is second hole 3, and two rows of pore structures are arranged in turn, and the direction of arrangement of every row of pore structures is the same for the direction of arrangement of each row of pore structures is parallel to each other, and the interval setting between each hole of each row of pore structures.
Preferably, the ratio of the sum of the opening areas of the first holes 2 and the second holes 3 to the area of the dynamic pressure lubricating surface 1 is 0.05-0.5, so that the dynamic pressure lubricating effect of the surface lubricating texture can be ensured, and the problem of insufficient structural strength of the dynamic pressure lubricating surface 1 caused by overlarge hole structural area is avoided.
When the friction pair is in work, fluid medium flows into a texture lubrication area along a friction pair clearance channel under the shearing action in the movement process of the friction pair, fluid is enriched and accumulated on the wedge-shaped convergence side of the micropores, a remarkable dynamic pressure effect is generated, the bearing capacity of a fluid film is improved, the friction end face is rapidly separated, and the non-contact operation state is achieved. On one hand, in the deep hole, in the direction far away from the dynamic pressure lubrication surface, the fluid movement direction is opposite to the texture inclination direction, the fluid flows out of the hole area along the inclined surface of the deep hole, a lubrication fluid film is formed on the end surface, the bottom of the deep hole forms a negative pressure cavity due to the outflow of a medium, the pressure of the fluid film on the end surface and the negative pressure of the cavity act to form a pressure difference force in the direction opposite to the fluid movement direction, the negative pressure effect of the cavity is gradually enhanced along with the continuous outflow of the medium out of the deep hole, and when the pressure difference force is greater than the shearing force, the lubrication; on the other hand, because of the size mutation effect formed by the large ratio of the depth of the deep hole to the size of the lubricating gap, the fluid medium entering or flowing out of the deep hole generates a vortex phenomenon, as shown in fig. 4, the generation of the vortex increases the flow resistance of the medium, remarkably increases the end surface damping effect, and can further improve the hydrodynamic effect by matching with the microporous structure. Therefore, through the combined action of the deep hole and the micropores, the friction pair can be ensured to be in a fluid dynamic pressure lubrication state for a long time, surface friction abrasion is avoided, and external continuous oil supply is not needed.
The surface lubrication texture of the first embodiment of the present application is particularly useful for hydrodynamic lubrication improvement between friction pairs that slide unidirectionally.
Referring collectively to fig. 5, according to a second embodiment of the present application, which is substantially the same as the first embodiment, except that in the present embodiment, the second holes 3 have an increasing cross-sectional area in the direction close to the hydrodynamic lubrication surface 1.
In this embodiment, the inclined hole has adopted the pore structure of cross section gradual change, and the aperture of deep hole reduces to the bottom by the surface gradually, and the variable cross section deep hole is changeed and is aroused downthehole negative pressure to produce, and makes outside the difficult outflow hole of oil storage, consequently can have better oil storage effect.
Referring collectively to fig. 6, a third embodiment according to the present application is substantially the same as the first embodiment except that in the present embodiment, the second holes 3 comprise two inclined holes, one of which is inclined in a direction away from the hydrodynamic lubrication surface 1 in a direction opposite to the first flow direction of the fluid and the other of which is inclined in a direction opposite to the second flow direction of the fluid.
Preferably, one inclined hole and the other inclined hole share the same opening, so that the hole structure can be simplified, the opening area is reduced, the hole structure is more conveniently arranged, and the problem of insufficient strength of a friction pair structure is avoided.
Preferably, one inclined hole and the other inclined hole are symmetrically arranged. The second hole 3 in this embodiment is a deep hole structure symmetrically distributed in two directions, and besides the negative pressure oil storage effect, the symmetrical distribution structure does not limit the movement direction of the friction end face, allows two-way movement, and can be applied to a reciprocating friction pair.
In one embodiment, not shown in the figures, the first holes 2 are perpendicular to the hydrodynamic lubrication surface 1 and the second holes 3 are perpendicular to the hydrodynamic lubrication surface 1. In the present embodiment, the central axis of the second hole 3 is perpendicular to the hydrodynamic lubrication surface 1, and since the second hole 3 is a deep hole, it can also perform an effective oil storage function. In order to reduce the resistance of the second hole 3 to oil discharge caused by the hole structure perpendicular to the dynamic pressure lubricating surface 1, the second hole 3 may preferably adopt an inclined side structure with a large upper part and a small lower part, so that the fluid medium can be more conveniently taken out from the second hole 3 under the action of the fluid flow on the dynamic pressure lubricating surface 1 and participate in the lubricating process between the friction pairs.
