Description

Technical Field

[0001] The utility model relates to the technical field of compressor eccentric sleeves, and specifically relates to a new type of compressor eccentric sleeve. Background Art

[0002] An air-conditioning compressor plays a role in compressing and driving the refrigerant in the air-conditioning refrigerant circuit. In a scroll compressor, a back-pressure chamber is formed between the back-pressure chamber bracket and the moving disk. The eccentric sleeve is located in the back-pressure chamber and is connected to the crankshaft, mainly playing a role in balancing the shafting during rotation.

[0003] For example, in the utility model: "A new type of compressor eccentric sleeve", the publication number is: "CN219733638U". Through the arrangement of oil delivery holes, dispersion holes, and communication holes, the lubricating oil between the eccentric shaft and the mounting hole can communicate with the outside of the eccentric sleeve body, which is beneficial to improving the heat dissipation and lubrication effects of the eccentric sleeve body. However, during the implementation of this patent, there is a lack of a support structure inside the upper ring oil groove and the lower ring oil groove, making the eccentric sleeve prone to deformation under force, and the internal heat dissipation area of the upper ring oil groove and the lower ring oil groove is relatively small, greatly reducing the heat dissipation effect of the eccentric sleeve. Therefore, there is an urgent need for a new type of compressor eccentric sleeve to solve the above problems. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a new type of compressor eccentric sleeve to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A new type of compressor eccentric sleeve, including an eccentric sleeve body, a lower ring oil groove, an upper ring oil groove, and an eccentric part of the eccentric sleeve. An internal oil delivery groove is arranged inside the eccentric sleeve body, and an eccentric part of the eccentric sleeve is installed inside the eccentric sleeve body. The upper ring oil groove is arranged at the top of the eccentric sleeve body, and the lower ring oil groove is arranged at the bottom of the eccentric sleeve body. First oil distribution holes are evenly arranged at the top of the internal oil delivery groove, and the first oil distribution holes are all communicated with the upper ring oil groove. Second oil distribution holes are evenly arranged at the bottom of the internal oil delivery groove, and the second oil distribution holes are all communicated with the lower ring oil groove. An installation hole is arranged inside the eccentric part of the eccentric sleeve.

[0006] Preferably, second metal support columns are evenly installed inside the lower ring oil groove.

[0007] Preferably, second heat dissipation fins are evenly installed on the outer sides of the second metal support columns.

[0008] Preferably, first metal support columns are evenly installed inside the upper ring oil groove.

[0009] Preferably, first heat dissipation fins are evenly installed on the outer sides of the first metal support columns.

[0010] Preferably, oil delivery through-holes are evenly arranged on the outer side of the eccentric sleeve body, and all the oil delivery through-holes are communicated with the internal oil delivery groove.

[0011] Preferably, oil guiding through-holes are evenly arranged on the outer side of the eccentric part of the eccentric sleeve, and all the oil guiding through-holes are communicated with the mounting holes.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The eccentric sleeve of the new compressor is provided with a first metal support column and a second metal support column. The interiors of the upper ring oil groove and the lower ring oil groove can be supported respectively through the first metal support column and the second metal support column, which is beneficial to improving the overall structural strength of the eccentric sleeve body and avoiding the deformation of the eccentric sleeve body due to stress.

[0014] 2. The eccentric sleeve of the new compressor is provided with a first heat dissipation fin and a second heat dissipation fin. The heat dissipation area of the eccentric sleeve body can be increased through the first metal support column and the first heat dissipation fin. When used in cooperation with the upper ring oil groove, the heat on the eccentric sleeve body can be quickly dissipated. Moreover, the heat dissipation area of the eccentric sleeve body can be increased through the second metal support column and the second heat dissipation fin. When used in cooperation with the lower ring oil groove, the heat on the eccentric sleeve body can be quickly dissipated, thereby effectively improving the heat dissipation effect.

[0015] 3. The eccentric sleeve of the new compressor is provided with a first oil distribution hole, an internal oil delivery groove and a second oil distribution hole. After the oil fluid enters the interior of the internal oil delivery groove through the oil delivery through-holes, it can first flow into the interior of the upper ring oil groove through the first oil distribution hole, and then flow into the interior of the lower ring oil groove through the second oil distribution hole, which can avoid the situation that the oil fluid all flows into the interior of the lower ring oil groove under the influence of gravity and cannot flow into the interior of the upper ring oil groove, thereby avoiding affecting the local heat dissipation and lubrication effects of the eccentric sleeve body.

[0021] Please refer to Figures 1-3 , an embodiment provided by the present utility model: a new type of compressor eccentric sleeve, including an eccentric sleeve body 1, a lower ring oil groove 2, an upper ring oil groove 4, and an eccentric part 7 of the eccentric sleeve. An internal oil delivery groove 13 is provided inside the eccentric sleeve body 1, and the eccentric part 7 of the eccentric sleeve is installed inside the eccentric sleeve body 1. The upper part of the eccentric sleeve body 1 is provided with the upper ring oil groove 4, and the lower part of the eccentric sleeve body 1 is provided with the lower ring oil groove 2. First oil distribution holes 12 are evenly provided at the top of the internal oil delivery groove 13, and the first oil distribution holes 12 are all communicated with the upper ring oil groove 4. Second oil distribution holes 14 are evenly provided at the bottom of the internal oil delivery groove 13, and the second oil distribution holes 14 are all communicated with the lower ring oil groove 2. An installation hole 8 is provided inside the eccentric part 7 of the eccentric sleeve.

[0022] As Figure 1 shown, second metal support columns 10 are evenly installed inside the lower ring oil groove 2, and second heat dissipation fins 11 are evenly installed on the outer sides of the second metal support columns 10. The heat dissipation area of the eccentric sleeve body 1 can be increased through the second metal support columns 10 and the second heat dissipation fins 11. When used in cooperation with the lower ring oil groove 2, the heat on the eccentric sleeve body 1 can be quickly dissipated.

[0023] As Figures 1-3 shown, first metal support columns 5 are evenly installed inside the upper ring oil groove 4, and first heat dissipation fins 6 are evenly installed on the outer sides of the first metal support columns 5. The heat dissipation area of the eccentric sleeve body 1 can be increased through the first metal support columns 5 and the first heat dissipation fins 6. When used in cooperation with the upper ring oil groove 4, the heat on the eccentric sleeve body 1 can be quickly dissipated.

[0024] As Figures 1-3 shown, oil delivery through holes 3 are evenly provided on the outer side of the eccentric sleeve body 1, and the oil delivery through holes 3 are all communicated with the internal oil delivery groove 13.

[0025] As Figures 1-3 shown, oil guiding through holes 9 are evenly provided on the outer side of the eccentric part 7 of the eccentric sleeve, and the oil guiding through holes 9 are all communicated with the installation hole 8. When oil flows into the inside of the oil guiding through holes 9 through the internal oil delivery groove 13 at the same time, the eccentric sleeve body 1 and the eccentric part 7 of the eccentric sleeve can be lubricated, and the oil can exchange heat with the eccentric sleeve body 1 and the eccentric part 7 of the eccentric sleeve, which can help the eccentric sleeve body 1 and the eccentric part 7 of the eccentric sleeve dissipate heat.

[0026] Working principle:

[0027] During use, the oil fluid enters the interior of the internal oil delivery groove 13 through the oil delivery through-hole 3. The oil fluid first divides through the internal oil delivery groove 13 and enters the interior of the first oil distribution hole 12, and enters the interior of the upper ring oil groove 4 through the first oil distribution hole 12;

[0028] The oil fluid continues to flow into the interior of the internal oil delivery groove 13, so that the oil fluid enters the interior of the second oil distribution hole 14 through the internal oil delivery groove 13, and then enters the interior of the lower ring oil groove 2 through the second oil distribution hole 14;

[0029] The oil fluid simultaneously flows into the oil guiding through-hole 9 through the internal oil delivery groove 13, so as to lubricate the eccentric sleeve body 1 and the eccentric part 7 of the eccentric sleeve, and the oil fluid can perform heat exchange with the eccentric sleeve body 1 and the eccentric part 7 of the eccentric sleeve, which can help the eccentric sleeve body 1 and the eccentric part 7 of the eccentric sleeve dissipate heat;

[0030] During use, the interiors of the upper ring oil groove 4 and the lower ring oil groove 2 can be supported respectively by the first metal support column 5 and the second metal support column 10, which is beneficial to improving the overall structural strength of the eccentric sleeve body 1 and avoiding deformation of the eccentric sleeve body 1 due to force;

[0031] The heat dissipation area of the eccentric sleeve body 1 can be increased through the first metal support column 5 and the first heat dissipation fin 6. When used in cooperation with the upper ring oil groove 4, the heat on the eccentric sleeve body 1 can be quickly dissipated. And the heat dissipation area of the eccentric sleeve body 1 can be increased through the second metal support column 10 and the second heat dissipation fin 11. When used in cooperation with the lower ring oil groove 2, the heat on the eccentric sleeve body 1 can be quickly dissipated, so that the heat dissipation effect can be effectively improved.
