Abstract
Description
Technical Field
[0001] This invention relates to the field of scroll compressor technology, and more particularly to a moving scroll plate, a processing method, and a scroll compressor. Background Technology
[0002] Scroll compressors, with their compact structure, stable operation, low noise, and high energy efficiency, are widely used in refrigeration, air conditioning, medical devices, and new energy vehicles. A scroll compressor consists of a stationary scroll and a moving scroll. The moving and stationary scrolls rotate relative to each other, forming a series of crescent-shaped closed working chambers at the meshing point, thus compressing the gas. During this process, the material properties, surface condition, and meshing precision of the moving and stationary scrolls directly determine the sealing performance of the compression chamber and the overall reliability of the compressor. To meet lightweight requirements, both the moving and stationary scrolls are generally made of lightweight cast aluminum. However, the homogeneous pairing of the moving and stationary scrolls is prone to adhesive wear during high-speed meshing, affecting the overall lifespan and efficiency of the compressor. Meanwhile, there is a tiny working gap between the moving and stationary scroll plates to achieve relative motion. The size control of this gap is extremely critical. If the sealing gap is too small, the frictional resistance will increase dramatically, accelerating wear and generating noise, and increasing energy consumption. If the sealing gap is too large, the leakage of working fluid will increase, resulting in a decrease in exhaust volume and pressure, which will seriously restrict the overall efficiency and reliability under high pressure conditions.
[0003] Therefore, a moving scroll plate, a processing method, and a scroll compressor are needed to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a moving scroll plate, a processing method, and a scroll compressor to solve the problem of reduced overall machine life and efficiency caused by the easy adhesion and wear of the moving and stationary scroll plates when they rotate around each other due to their homogeneous pairing.

[0006] As an optional technical solution, the mating surface includes a first mating surface, a second mating surface, and a third mating surface. The end face of the moving vortex tooth portion that is axially away from the substrate is the first mating surface. The end face of the moving vortex tooth portion that is radially toward the stationary vortex disk is the second mating surface. The third mating surface is located on the end face of the substrate that is axially toward the stationary vortex disk, and the third mating surface and the second mating surface are connected.
[0007] As an optional technical solution, the axial projection of the stationary vortex tooth portion of the stationary vortex disk is entirely within the range of the third mating surface.
[0008] As an optional technical solution, the moving scroll disk further includes a wear-resistant layer, which is disposed between the substrate and the plastic metal layer.

This type of moving scroll disk features a plastic metal layer on the mating surface that forms the compression cavity with the stationary scroll disk. This plastic metal layer can generate micro-plastic deformation in local high-pressure areas, matching the pressure distribution. When used with the stationary scroll disk, it forms an adaptive dynamic compensation mechanism, resulting in a dynamic, non-uniformly distributed preset gap between the moving and stationary scroll disks. The sealing interface actively follows the gap changes, maintaining effective contact at all times, thus ensuring the blocking of the main leakage path. It also improves the damping and vibration reduction performance of the moving scroll disk. Furthermore, the plastic metal layer, located on the outermost side, bears the main frictional loss, effectively reducing direct wear on the main body and providing protection for the internal body. This ensures the structural strength of the moving scroll disk, thus simultaneously achieving the dual goals of reducing leakage and minimizing wear, resulting in excellent economic efficiency.

Furthermore, by performing surface activity enhancement treatment on the wear-resistant layer before connecting the plastic metal layer and the wear-resistant layer, the connection reliability of the plastic metal layer and the wear-resistant layer can be improved, ensuring the reliability and stability of the performance of the formed dynamic scroll disk.
[0015] On the other hand, the present invention provides a scroll compressor, including a stationary scroll disk and a moving scroll disk in any of the above embodiments, wherein the stationary scroll disk includes a stationary scroll tooth portion, and the stationary scroll tooth portion and the moving scroll tooth portion of the moving scroll disk are configured to form a compression chamber.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0023] Example 1 like Figure 2 As shown, this embodiment provides a moving scroll disk 10, which includes a body, a base plate 11 and a moving scroll tooth portion 12. The moving scroll tooth portion 12 and the base plate 11 are fixedly connected. The moving scroll disk 10 is provided with a mating surface, which is used to cooperate with a stationary scroll disk 20 to form a compression cavity. At least one mating surface of the moving scroll tooth portion 12 is provided with a plastic metal layer 13. The surface of the plastic metal layer 13 facing the stationary scroll disk 20 and the surface of the stationary scroll disk 20 facing the moving scroll disk 10 together define a preset gap.
[0024] In this embodiment, the moving scroll plate 10 has a plastic metal layer 13 on the mating surface that forms a compression cavity with the stationary scroll plate 20. The plastic metal layer 13 can generate a small amount of plastic deformation in the local high-pressure area that matches the pressure distribution. When used with the stationary scroll plate 20, it can form an adaptive dynamic supplementation mechanism, so that the working gap between the moving scroll plate 10 and the stationary scroll plate 20 is a preset gap that is dynamically and non-uniformly distributed. The sealing interface can actively follow the gap change and always maintain an effective fit, thereby ensuring that the main leakage path is blocked. At the same time, it improves the damping and vibration reduction performance of the moving scroll plate 10. Furthermore, the plastic metal layer 13 is located on the outermost side and bears the main friction loss, effectively reducing the direct wear of the body and protecting the internal body. This ensures the structural strength of the moving scroll plate 10 and simultaneously achieves the dual purpose of reducing leakage and reducing wear, resulting in excellent economic efficiency.
[0025] Furthermore, the mating surfaces include a first mating surface, a second mating surface, and a third mating surface. The end face of the moving vortex tooth portion 12 that is axially away from the substrate 11 is the first mating surface. The end face of the moving vortex tooth portion 12 that is radially toward the stationary vortex disk 20 is the second mating surface. The third mating surface is located on the end face of the substrate 11 that is axially toward the stationary vortex disk 20, and the third mating surface and the second mating surface are connected.
[0026] Specifically, in this embodiment, by setting the end face of the moving vortex tooth 12 away from the substrate 11 along the axial direction as the first mating surface, the end face of the moving vortex tooth 12 facing the stationary vortex disk 20 along the radial direction as the second mating surface, and the third mating surface located on the end face of the substrate 11 facing the stationary vortex disk 20 along the axial direction, and the third mating surface and the second mating surface being connected, it is possible to ensure that a stable preset gap is formed between the moving vortex disk 10 and the stationary vortex disk 20, thereby improving the performance of the moving vortex disk 10.
[0027] Optionally, in this embodiment, the plastic metal layer 13 is provided only on the first mating surface, the second mating surface and the third mating surface, so as to minimize the amount of soft metal used while ensuring the sealing effect, thereby reducing material costs and process difficulty.
[0028] Furthermore, the projection of the stationary vortex tooth portion 21 of the stationary vortex disk 20 along the axial direction is entirely within the range of the third mating surface.
[0029] Specifically, in this embodiment, this arrangement ensures that the plastic metal layer 13 can completely cover the area of relative friction between the stationary scroll plate 20 and the moving scroll plate 10, thereby ensuring that the plastic metal layer 13 performs better and improving the performance of the moving scroll plate 10.
[0030] Furthermore, the moving scroll disk 10 also includes a wear-resistant layer 14, which is disposed between the substrate 11 and the plastic metal layer 13.
[0031] Specifically, in this embodiment, by setting the wear-resistant layer 14 between the substrate 11 and the plastic metal layer 13, the wear-resistant layer 14 can not only provide rigid support for the plastic metal layer 13, improve the connection reliability between the plastic metal layer 13 and the substrate 11, and ensure that the plastic metal layer 13 can achieve adaptive sealing and damping vibration reduction, but also improve the wear resistance of the moving scroll disk 10 along the axial direction. The two advantages complement each other and improve the performance of the moving scroll disk 10.
[0032] Optionally, in this embodiment, the wear-resistant layer 14 is a non-metallic wear-resistant layer, such as titanium oxide (TiO2), ceramics, etc.
[0033] Furthermore, the body is made of aluminum alloy, and the hardness of the body ranges from 60HB to 80HB.
[0034] Specifically, in this embodiment, by setting the hardness of the body to a range of 60HB-80HB, it can be ensured that the body has sufficient hardness to bear frictional wear. At the same time, relying on its self-lubricating properties, a transfer film is formed when sliding relative to the end face of the aluminum stationary disk, which avoids excessive wear on the grinding parts and ensures stable bonding with the wear-resistant layer 14.
[0035] Furthermore, the plastic metal layer 13 is made of a copper-based alloy material.
[0036] Optionally, the plastic metal layer 13 is a lead bronze layer, and the hardness of the lead bronze layer ranges from 245HB to 635HB.
[0037] Specifically, when the plastic metal layer 13 is a lead bronze layer, its hardness ranges from 245HB to 635HB, its elongation is 5% to 6%, and it has excellent self-lubricating properties, which can improve the smoothness of the relative movement of the moving scroll plate 10 and the stationary scroll plate 20. At the same time, it has high hardness and good wear resistance.
[0038] Optionally, the ductile metal layer 13 is a tin bronze layer, and the hardness of the tin bronze layer is ≥885HB.
[0039] Specifically, when the plastic metal layer 13 is a tin bronze layer, its hardness is greater than 885HB, its elongation is ≥6%, and its wear resistance is excellent, making it suitable for high-load working conditions.
[0040] Optionally, the ductile metal layer 13 is a high-strength brass layer, and the hardness of the high-strength brass layer is in the range of 100HB-200HB.
[0041] Specifically, when the ductile metal layer 13 is a high-strength brass layer, its hardness ranges from 100HB to 200HB, its elongation is ≥10%, it has good machinability, is easy to process, and reduces processing costs.
[0042] Optionally, the plastic metal layer 13 is a pure copper layer.
[0043] Specifically, when the plastic metal layer 13 is a pure copper layer, the hardness is about 150HB, the elongation is ≥30%, the plasticity is optimal, and it can significantly improve the sealing effect between the moving scroll plate 10 and the stationary scroll plate 20.
[0044] Optionally, the specific material and hardness of the plastic metal layer 13 can be set according to the actual use scenario, and no specific restrictions are imposed here.
[0045] Example 2 like Figure 1 and Figure 3 As shown, this embodiment provides a moving scroll disk 10. The difference between this moving scroll disk 10 and the moving scroll disk 10 in Embodiment 1 is that the entire outer surface of the moving scroll disk 10 in this embodiment is covered with the aforementioned plastic metal layer 13.
[0046] Specifically, in this embodiment, the moving scroll plate 10, by wrapping the entire outer surface of its body with the aforementioned plastic metal layer 13, forms a continuous and complete sealing barrier, thereby achieving an ultimate sealing effect with no dead angles and high wear tolerance. During the relative operation of the moving scroll plate 10 and the stationary scroll plate 20, the outer plastic metal layer 13 can act as a whole, generating coordinated and controllable plastic deformation. This overall deformation can systematically compensate for overall gap deviations caused by manufacturing, assembly, and complex loads, rather than only compensating for local points. When a local surface wears, the plastic metal in the remaining areas can still maintain its sealing function, thereby significantly improving fault tolerance and life margin. At the same time, the continuous wrapping also has damping and vibration reduction characteristics, which helps to reduce operating noise, thereby improving the overall performance of the moving scroll plate 10.
[0047] Furthermore, in this embodiment, the moving scroll disk 10 also includes a wear-resistant layer 14, which is wrapped around the entire outer surface of the body and located between the outer surface of the body and the plastic metal layer 13. This makes the entire moving scroll disk 10 form a three-layer composite structure of an aluminum alloy base, a wear-resistant layer 14, and a plastic metal layer 13. This ensures that the moving scroll disk 10 has good structural strength and can also ensure good sealing performance and effectively reduce wear during the relative operation of the moving scroll disk 10 and the stationary scroll disk 20.
[0048] Example 3 like Figure 4 As shown, this embodiment provides a processing method for processing the aforementioned moving scroll disk 10, including: S10. Activate the outer surface of the body.
[0049] Specifically, in this embodiment, the method for activating the outer surface of the body includes removing grease, contaminants, oxides and adsorbed gases from the surface of the body through the above operations, thereby improving surface activity and enhancing the adhesion of the body surface.
[0050] S20. Prepare a wear-resistant layer 14 on the substrate.
[0051] Specifically, in this embodiment, a wear-resistant layer 14 is deposited using a vapor deposition process at a temperature lower than the tempering temperature of the substrate. The gradient transition layer design ensures the bonding strength, thereby ensuring the structural strength of the substrate itself and thus ensuring the performance of the moving scroll disk 10.
[0052] S30. Surface activity enhancement treatment is applied to the wear-resistant layer 14.
[0053] Specifically, in this embodiment, the surface activity enhancement treatment of the wear-resistant layer 14 involves plasma activation or ion beam etching of the wear-resistant layer 14. This improves the reliability and stability of the connection between the plastic metal layer 13 and the wear-resistant layer 14.
[0054] S40. The plastic metal layer 13 is disposed on the surface of the wear-resistant layer 14.
[0055] Specifically, in this embodiment, a plastic metal layer 13 is disposed on the surface of the wear-resistant layer 14 through a composite process to form a transition piece. This ensures that the transition piece forms a three-layer composite structure of an aluminum alloy base, a wear-resistant layer 14, and a plastic metal layer 13. This allows the moving scroll plate 10 to have good structural strength and also ensure good sealing performance and reduce wear during the relative operation of the moving scroll plate 10 and the stationary scroll plate 20.
[0056] Optionally, in this embodiment, the composite process can be any one or more combinations of electroplating, casting, rolling or hot isostatic pressing, without any specific limitations.
[0057] Following S40 are: S50. The transition part is subjected to stress relief treatment and machining to form the moving scroll disk 10.
[0058] Specifically, in this embodiment, stress is removed by annealing and the dimensional accuracy of the formed moving scroll disk 10 is ensured by machining.
[0059] Example 4 like Figures 1 to 3As shown, this embodiment provides a scroll compressor, including a stationary scroll plate 20 and a moving scroll plate 10 as in Embodiment 1 or Embodiment 2. The stationary scroll plate 20 includes a stationary scroll tooth portion 21. The stationary scroll tooth portion 21 and the moving scroll tooth portion 12 of the moving scroll plate 10 are configured to form a compression chamber. An air outlet 22 is provided at the end of the stationary scroll plate 20 away from the moving scroll plate 10.
[0060] Specifically, in this embodiment, the scroll compressor is equipped with the aforementioned moving scroll disk 10, which enables the moving scroll disk 10 and the stationary scroll disk 20 to overcome adhesive wear caused by homogeneous pairing when they rotate relative to each other, thereby extending the service life of the scroll compressor. Furthermore, the plastic metal layer 13 of the moving scroll disk 10 can generate a small amount of plastic deformation in the local high-pressure area that matches the pressure distribution, filling and compensating for the gap in real time. The sealing interface can actively follow the gap change and always maintain effective contact, thereby ensuring the performance of the scroll compressor.
