Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more specifically, to a support assembly and a compressor having the same. Background Technology

[0002] Currently, scroll compressors are widely used in refrigeration, air conditioning, and heat pump industries due to their high efficiency, small size, light weight, and stable operation. They typically employ either a top thrust or bottom thrust structure to axially limit the crankshaft assembly during compressor operation. In a bottom thrust structure, the tail end of the crankshaft directly contacts the bottom thrust structure. Thus, during the long-term rotation of the crankshaft, wear inevitably occurs on the contact surface of the bottom thrust structure, producing a certain amount of wear debris that remains in the cavity between the lower support and the bottom thrust structure.

[0003] However, during the long-term operation of the scroll compressor, these wear debris will enter and accumulate inside the filter screen. Over time, this wear debris will be drawn back into the oil pump, causing blockages in the internal channels and affecting the normal operation of the pump gears. Ultimately, this will impact the normal operation of the oil pump, pumping efficiency, and the long-term reliability of the compressor. Summary of the Invention

[0067] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0068] like Figures 1 to 9 As shown, Embodiment 1 of the present invention provides a support assembly, which includes: a support base 10, a filter element 20, a stop element 30, a crankshaft structure 40, and a hydraulic pump 50 located in a filter chamber 21, all interconnected. The support base 10 is provided with a clearance through hole 11, and the filter element 20 and the support base 10 form a filter chamber 21. The stop element 30 is fixed to the bottom of the support base 10. A portion of the crankshaft structure 40 is rotatably disposed in the clearance through hole 11 and supported on the stop element 30. The stop element 30 is provided with an oil passage hole 31, and another portion of the crankshaft structure 40 passes through the oil passage hole 31 and is connected to the hydraulic pump 50. An oil inlet channel 61 is formed between the wall of the oil passage hole 31 and the other portion of the crankshaft structure 40, and a connecting channel 62 communicating with the oil inlet channel 61 is formed between the stop element 30 and the portion of the crankshaft structure 40. The support base 10 is provided with an oil passage 63. The oil inlet end of the oil passage 63 is connected to the connecting passage 62, and the oil outlet end of the oil passage 63 is located outside the filter chamber 21.

[0069] The support assembly provided in this embodiment, with its oil inlet channel 61, connecting channel 62, and oil outlet channel 63, allows the negative pressure generated by the hydraulic pump 50 during operation to first draw lubricating oil into the oil inlet 31 (i.e., into the oil inlet channel 61), then into the connecting channel 62, and finally into the oil outlet channel 63. When the crankshaft structure 40 moves relative to the stop member 30 and wear debris is generated due to friction, the lubricating oil flowing through the connecting channel 62 carries away the wear debris and sends it out of the filter chamber 21 through the oil outlet channel 63. This avoids a large amount of wear debris remaining in the filter chamber 21 and being easily drawn into the hydraulic pump 50, thus better preventing the impact on the normal operation of the hydraulic pump 50. Therefore, the support assembly provided by this invention can solve the technical problem in the prior art where wear debris generated at the tail of the crankshaft structure 40 due to wear is easily drawn into the oil pump.

[0070] Specifically, the part of the crankshaft structure 40 that contacts the stop member 30 is generally made of metal, and the corresponding wear debris is metal shavings. Specifically, the part of the crankshaft structure 40 that contacts the stop member 30 is generally made of a material containing iron, and the corresponding wear debris is iron shavings. Specifically, the filter element 20 includes a filter screen, and the hydraulic pump 50 can be an oil pump.

[0071] In this embodiment, the stop member 30 has a support surface 32 for supporting a portion of the crankshaft structure 40, and the portion of the crankshaft structure 40 has a contact surface for contacting the support surface 32. The connecting channel 62 includes a first oil drainage groove 621. The first oil drainage groove 621 is provided on the support surface 32 and / or the contact surface. This arrangement facilitates effective oil drainage through the first oil drainage groove 621 and also facilitates the collection of wear debris generated by friction between the contact surface and the support surface 32. Therefore, when the lubricating oil flows through the first oil drainage groove 621, it can smoothly carry away the wear debris, allowing the wear debris to flow out of the filter chamber 21.

[0072] Specifically, when both the support surface 32 and the contact surface are provided with a first oil-flowing groove 621, the first oil-flowing groove 621 on the support surface 32 and the first oil-flowing groove 621 on the contact surface can be arranged opposite to each other. Specifically, at least a portion of the first oil-flowing groove 621 is located between the support surface 32 and the contact surface.

[0073] Specifically, the first oil channel groove 621 extends radially along the oil passage hole 31, and there are multiple first oil channel grooves 621 arranged circumferentially around the oil passage hole 31. The connecting channel 62 also includes a second oil channel groove 622, which is provided on the support surface 32. The multiple first oil channel grooves 621 are all connected to the second oil channel groove 622, and the oil inlet end of the oil channel 63 is connected to the second oil channel groove 622. With this structural arrangement, the multiple first oil channel grooves 621 can better collect the wear debris generated by the friction between the crankshaft structure 40 and the stop member 30, and the wear debris collected by the multiple first oil channel grooves 621 is transferred to the second oil channel groove 622 through the lubricating oil. Then, the lubricating oil in the second oil channel groove 622 carries the wear debris into the oil channel 63, and the lubricating oil carrying the wear debris is discharged to the outside of the filter chamber 21 through the oil channel 63. In addition, this multi-path lubricant flow design not only improves the flow efficiency of lubricant but also increases the circulation path of lubricant, making the distribution of lubricant more uniform. This facilitates the lubricant to carry wear debris out of the filter chamber 21 more effectively, thereby avoiding the impact of wear debris on the operation of the hydraulic pump 50 and improving the operating stability and efficiency of the compressor.

[0074] Specifically, the oil inlet end of the oil channel 63 can be positioned opposite to at least a portion of the second oil channel groove 622, with the oil inlet end of the oil channel 63 located above the second oil channel groove 622.

[0075] Specifically, along the extension direction from the bottom to the opening of the first oil channel groove 621, the flow cross-section of the first oil channel groove 621 gradually increases. This structural design facilitates the smooth entry of wear debris generated by the friction between the crankshaft structure 40 and the stop member 30 into the first oil channel groove 621, preventing the wear debris from being unable to enter smoothly due to a small flow cross-section at the opening of the first oil channel groove 621. Furthermore, this structural design also avoids the situation where excessive hollowing of the corresponding structure due to an excessively large opening volume of the first oil channel groove 621 could lead to insufficient structural strength. This gradually changing flow cross-section design effectively reduces the resistance of lubricating oil during flow and increases the flow speed of the lubricating oil.

[0076] Specifically, "the flow cross-section of the first oil flow groove 621 gradually increases along the extension direction from the bottom of the first oil flow groove 621 to the opening of the first oil flow groove 621" can be understood as "the flow cross-section of the first oil flow groove 621 gradually increases along the extension direction from the side of the stop member 30 near the hydraulic pump 50 to the side of the stop member 30 away from the hydraulic pump 50".

[0077] Specifically, along the extension direction from the bottom to the opening of the second oil-carrying groove 622, the flow cross-section of the second oil-carrying groove 622 gradually increases. This facilitates the smooth entry of wear debris from the first oil-carrying groove 621 into the second oil-carrying groove 622, preventing wear debris from being unable to enter smoothly due to a small flow cross-section at the opening of the second oil-carrying groove 622. Furthermore, this structural design also avoids the situation where excessive hollowing out of the corresponding structure due to an excessively large opening volume in the second oil-carrying groove 622 could lead to insufficient structural strength. This gradually changing flow cross-section design effectively reduces the resistance of lubricating oil during flow and increases the flow speed of lubricating oil.

[0078] Specifically, "the flow cross-section of the second oil flow groove 622 gradually increases along the extension direction from the bottom of the second oil flow groove 622 to the opening of the second oil flow groove 622" can be understood as "the flow cross-section of the second oil flow groove 622 gradually increases along the extension direction from the side of the stop member 30 near the hydraulic pump 50 to the side of the stop member 30 away from the hydraulic pump 50".

[0079] In this embodiment, the first oil-flowing groove 621 is a V-shaped groove. This structure ensures that wear debris generated by the friction between the crankshaft structure 40 and the stop member 30 can smoothly enter the first oil-flowing groove 621, avoiding the situation where wear debris cannot smoothly enter due to the small flow cross-section at the opening of the first oil-flowing groove 621. Furthermore, the above structure also avoids the situation where excessive hollowing of the corresponding structure due to an excessively large opening volume of the first oil-flowing groove 621 can lead to insufficient structural strength. Specifically, in this embodiment, the first oil-flowing groove 621 is disposed on the support surface 32.

[0080] In this embodiment, the second oil-flowing groove 622 is an annular groove, which facilitates the collection of wear debris from the multiple first oil-flowing grooves 621 into the second oil-flowing groove 622. It also facilitates the collection of wear debris carried by the lubricating oil in the first oil-flowing grooves 621 into the second oil-flowing groove 622, thereby allowing the wear debris to be carried out of the filter chamber 21 by the flow of lubricating oil. Specifically, the second oil-flowing groove 622 is disposed on the support surface 32. Specifically, the annular groove can be a circular annular groove.

[0081] Specifically, the first oil-carrying groove 621 is a V-shaped inclined groove, with both sides of the V-shaped inclined groove being inclined surfaces, and three V-shaped inclined grooves can be evenly distributed along the circumference.

[0082] Specifically, the oil passage 63 includes a first oil passage 631 and a second oil passage 632. The first oil passage 631 extends axially along the avoidance through hole 11, with one end forming an oil inlet. The second oil passage 632 extends radially along the avoidance through hole 11, with one end connecting to the other end of the first oil passage 631, and the other end forming an oil outlet. This structural arrangement facilitates optimization of the flow path of the oil passage 63, allowing for better removal of wear debris through the flow of lubricating oil. Furthermore, this combined axial and radial oil passage 63 design effectively avoids dead zones in the lubricating oil circulation process, improving the smoothness of lubricating oil flow.

[0083] Specifically, the diameter of the first oil passage 631 is d1, where 1.5mm ≤ d1 ≤ 2mm. This facilitates the smooth introduction of wear debris into the first oil passage 631. If the diameter of the first oil passage 631 is too large, the hollow space on the support base 10 will be too large, affecting the support and connection stability of the support base 10; if the diameter of the first oil passage 631 is too small, wear debris will not be able to enter the first oil passage 631 smoothly. In addition, the above structure can also ensure the flow rate of lubricating oil to a certain extent, so as to facilitate the smooth carrying away of wear debris by the lubricating oil.

[0084] Specifically, the diameter of the second oil passage 632 is d2, where 1.5mm ≤ d2 ≤ 2mm. This facilitates the smooth introduction of wear debris into the second oil passage 632. If the diameter of the second oil passage 632 is too large, the hollow space on the support base 10 will be too large, affecting the support and connection stability of the support base 10; if the diameter of the second oil passage 632 is too small, wear debris will not be able to enter the second oil passage 632 smoothly. In addition, the above structure can also ensure the flow rate of lubricating oil to a certain extent, so as to facilitate the smooth carrying away of wear debris by the lubricating oil.

[0085] In one embodiment, the support base 10 is provided with a clearance portion 12, which is located outside the filter chamber 21 and extends through the upper and lower ends of the portion of the support base 10 located outside the filter chamber 21. This structural arrangement facilitates the flow of lubricating oil carrying wear debris down through the clearance portion 12, preventing accumulation at the support base 10. Specifically, the lubricating oil flowing down through the clearance portion 12 carries wear debris into the oil sump 81 located below the support base 10, effectively utilizing gravity to facilitate the return of lubricating oil to the oil sump 81, reducing the impact on the amount of lubricating oil in the oil sump 81 and achieving the recycling of lubricating oil.

[0086] Specifically, the support base 10 includes a main body 13 and at least two connecting protrusions 14. The main body 13 is provided with a clearance through hole 11 and an oil passage 63. The at least two connecting protrusions 14 are spaced apart circumferentially along the main body 13 and are all connected to the main body 13. The gap between two adjacent connecting protrusions 14 forms a clearance portion 12. This structural arrangement facilitates the optimization of the support base 10's structure, allows for the smooth flow of lubricating oil, and enables the connecting protrusions 14 to effectively provide connection and support.

[0087] In another embodiment, the support assembly further includes an oil conduit 70, which is disposed outside the filter chamber 21. One end of the oil conduit 70 is connected to the oil outlet, and the other end is located below the first end. This structural arrangement facilitates the smooth flow of lubricating oil from the oil outlet through the oil conduit 70 to the lower part, effectively utilizing gravity to remove wear debris mixed with the lubricating oil. This structure effectively guides the lubricating oil, facilitating its collection.

[0088] Specifically, the oil pipe 70 is a bent pipe. The above structure can effectively avoid other structures of the support assembly and facilitate the smooth guidance of lubricating oil.

[0089] Specifically, the other end of the oil pipe 70 is located below the part of the support seat 10 outside the filter chamber 21, so that the lubricating oil flowing out through the oil pipe 70 can smoothly avoid the support seat 10, avoid the lubricating oil flowing out through the oil pipe 70 from accumulating at the support seat 10, and also facilitate the collection of the flowing lubricating oil.

[0090] Specifically, at least a portion of the filter element 20 is located within the oil sump 81, and the other end of the oil pipe 70 extends into the oil sump 81. This arrangement facilitates the smooth flow of lubricating oil through the oil pipe 70 into the oil sump 81 located below the support base 10. Gravity is effectively utilized to carry away wear debris through the lubricating oil, thus facilitating the return of lubricating oil to the oil sump 81. This reduces the impact on the amount of lubricating oil in the oil sump 81 and achieves the recycling of the lubricating oil.

[0091] In this embodiment, the crankshaft structure 40 includes a crankshaft 41 and a connecting member 42. The crankshaft 41 has a connecting hole 411. The connecting member 42 includes a first connecting portion 421, a second connecting portion 422, and a third connecting portion 423 connected in sequence. The connecting member 42 has a communicating hole 424 that passes through the first connecting portion 421, the second connecting portion 422, and the third connecting portion 423, and the communicating hole 424 communicates with the connecting hole 411. The crankshaft 41, the first connecting portion 421, and the second connecting portion 422 form part of the crankshaft structure 40, and the third connecting portion 423 forms another part of the crankshaft structure 40. The first connecting portion 421 is installed in the connecting hole 411 and connected to the crankshaft 41. The second connecting portion 422 is located between the end of the crankshaft 41 and the stop member 30, and there is a communicating channel 62 between the second connecting portion 422 and the stop member 30. This structural design optimizes the connection between the crankshaft structure 40 and the hydraulic pump 50, ensuring that the crankshaft structure 40 can stably drive the hydraulic pump 50.

[0092] Specifically, the first connecting part 421 and the connecting hole 411 are interference fit.

[0093] Specifically, the stop member 30 in all the above embodiments can also be called the lower stop plate, that is, the lower stop plate located below the crankshaft structure 40.

[0094] Through the support components provided in the above embodiments, the sequential connection of the oil inlet channel 61, the connecting channel 62, and the oil outlet channel 63 enables the metal shavings generated by the contact rotation between the crankshaft structure 40 and the stop member 30 during the operation of the scroll compressor to be carried by the lubricating oil and enter the oil sump 81 at the bottom of the compressor. This avoids the metal shavings from entering the filter chamber 21 and the problem of metal shavings entering the oil pump and clogging the oil flow path, thus affecting the oil pump's oil supply efficiency. This ensures the long-term stable and efficient operation of the oil pump and the long-term reliability of the scroll compressor.

[0095] Embodiment 2 of the present invention provides a compressor, which includes: the support assembly and housing 80 provided above, wherein the support base 10 of the support assembly is fixedly installed inside the housing 80.

[0096] In this embodiment, the bottom of the housing 80 has an oil sump 81, a part of the crankshaft structure 40 and / or the stop 30 is made of iron; the compressor also includes a magnetic adsorption component 160, which is installed in the oil sump 81 and located outside the filter chamber 21 formed by the filter component 20 of the support assembly and the support seat 10 of the support assembly.

[0097] It should be noted that "a part of the crankshaft structure 40 and / or the stop 30 is made of iron" can be understood as a part of the crankshaft structure 40 and / or the stop 30 being made of pure iron or iron-containing materials.

[0098] Specifically, the support component is the support component provided above.

[0099] The magnetic adsorption component 160 is disposed opposite to the clearance portion 12 of the support assembly, so as to effectively adsorb iron-containing wear debris in the lubricating fluid flowing down through the clearance portion 12, thereby avoiding the wear debris from being dispersed in the oil sump 81, and better preventing the wear debris from passing through the filter pores of the filter element 20, thus making it easier to avoid clogging the filter pores of the filter element 20.

[0100] Specifically, the magnetic adsorption component 160 is positioned opposite to the other end of the oil pipe 70 of the support assembly, so that the magnetic adsorption component 160 can effectively adsorb iron-containing wear debris in the lubricating fluid flowing down from the other end of the oil pipe 70, thereby avoiding the wear debris from being dispersed in the oil sump 81, and better preventing the wear debris from avoiding the filter holes of the filter element 20, thus making it easier to avoid clogging the filter holes of the filter element 20.

[0101] Specifically, the magnetic adsorption component 160 is fixed to the bottom of the housing 80 to improve its adsorption effect and effectively adsorb wear debris deposited at the bottom of the oil sump 81. Specifically, the magnetic adsorption component 160 can be welded to the bottom of the housing 80.

[0102] Specifically, the magnetic adsorption component 160 has a ring-shaped structure, which is simple and easy to install and fix. Specifically, the magnetic poles of the magnetic adsorption component 160 are oriented along the axis of the ring structure. This allows the lubricating oil carrying wear debris to flow back and pass through the magnetic adsorption component 160 more accurately, making it easier for the magnetic adsorption component 160 to adsorb metal impurities and achieve a better impurity removal effect.

[0103] Specifically, the magnetic adsorption element 160 is spaced apart from the filter element 20 of the support assembly to better adsorb wear debris located near the filter element 20 in the oil sump 81.

[0104] Specifically, the magnetic adsorption element 160 can be a magnet, and the magnetic flux density of the magnetic adsorption element 160 is greater than 500 Gauss.

[0105] like Figure 1 As shown, the compressor in this embodiment is mainly a scroll compressor, which mainly includes a motor 100, an upper bracket 150, a lower bracket (also called a support base 10), a stationary scroll 130, a moving scroll 140, a cross slip ring 110, and a crankshaft 41. The stator of the motor 100 is fixed to the housing 80 by a heat-shrink fitting, and the upper bracket 150 is fixed to the housing 80 by spot welding. The moving scroll 140 and the stationary scroll 130 are mounted opposite each other on the upper bracket 150 with a phase angle difference of 180 degrees. The moving scroll 140 moves under the drive of the crankshaft 41, meshing with the stationary scroll 130 to form a series of mutually isolated crescent-shaped sealed cavities with continuously changing volumes. The stationary scroll 130 is fixed to the upper bracket 150 by screw fasteners. The lower bracket is fixed to the lower support ring 90 by screws, and the lower support ring 90 is then fixed to the housing 80 by spot welding. The housing 80 includes an upper cover 82, a cylindrical body 83, and a lower cover 84 connected in sequence.

[0106] When the compressor is running, the motor 100 drives the crankshaft 41 to rotate. The crank of the crankshaft 41 drives the moving scroll 140 to move. Under the anti-rotation restriction of the cross slip ring 110, the moving scroll 140 performs translational motion around the center of the crankshaft 41 with a fixed radius. The refrigerant entering from the suction pipe 120 is drawn into the crescent-shaped suction chamber formed by the moving scroll 140 and the stationary scroll. After compression, it is discharged from the exhaust port of the stationary scroll and enters the cavity between the upper cover 82 and the stationary scroll. Then, it enters the cavity between the upper support 150 and the motor 100 through the exhaust groove of the stationary scroll and the upper bracket 150. Part of it enters the lower end of the motor 100 through the flow groove between the motor 100 and the housing 80. Finally, the high-pressure exhaust refrigerant is discharged through the exhaust pipe.

[0107] like Figure 1 The image shown is a schematic diagram of the scroll compressor according to this invention patent. Figure 2 , Figure 3 and Figure 4 The diagram shown is a structural schematic of the support component. Figure 2 and Figure 3 The arrows indicate the direction of lubricating oil flow during compressor operation. Figure 5 The exploded view of the supporting components shows the oil pump and filter element 20 fixed to the lower bracket with screws. The lower thrust plate (also known as the stop element 30) is placed concentrically with the oil pump and lower bracket, and is wrapped between the lower bracket and the oil pump. The lower bracket is fixed below the lower support ring 90 with screws. Figure 6 , Figure 7 This is a structural diagram of the lower thrust plate and lower support components. The lower thrust plate has an oil passage hole 31 at its center for the insertion of the connecting piece 42. Three V-shaped grooves (corresponding to the first oil passage groove 621) are evenly arranged around the circumference. A circular annular groove (corresponding to the second oil passage groove 622) is opened at the end of the V-shaped groove and connected to it. The outer diameter of the circular annular groove should avoid interference with the screw hole 33 on the lower thrust plate. The inner diameter of the circular annular groove should be larger than the outer diameter of the oil passage hole 31. An axial flow hole (corresponding to the first oil passage hole 631) and a radial flow hole (corresponding to the second oil passage hole 632) are opened for the lower support to ensure that the circular annular groove is aligned with the axial flow hole of the lower support. A radial flow hole is opened at the end of the axial flow hole. The diameters of the axial flow hole and the radial flow hole should be between φ1.5mm and φ2mm to ensure that metal impurities can pass smoothly without generating excessive oil discharge resistance. The radial flow hole is connected to the compression chamber.

[0108] When the scroll compressor starts to operate, the drive drives the oil pump to run at high speed. The gears inside the oil pump mesh and rotate to generate negative pressure, which draws some of the lubricating oil from the bottom oil sump 81 of the compressor's lower cover 84 into the oil passage 31 at the center of the lower thrust plate. The lubricating oil, along the V-shaped groove, carries the metal impurities generated by the wear between the drive and the lower thrust plate to the circular annular groove. At this time, the lubricating oil carrying the metal impurities flows around the circular annular groove and then along the axial flow hole and radial flow hole at the lower support, discharging the metal impurities to the bottom oil sump 81 of the lower cover 84. Finally, the metal impurities are attracted to the magnet at the lower cover 84. The impurity removal flow path (corresponding to the sequentially connected oil inlet channel 61, connecting channel 62, and oil outlet channel 63) can effectively carry the metal impurities generated by the wear between the contact surface and the support surface 32 during compressor operation to the oil sump 81 at the bottom of the compressor and be attracted by the magnet at the lower cover 84. This avoids the problem of metal filings generated by drive wear during the operation of the scroll compressor being discharged and deposited at the bottom of the oil pump filter screen. Furthermore, during the operation of the compressor, these metal filings are carried into the interior by the lubricating oil, blocking the oil flow path and affecting the oil pump's oil supply efficiency to the pump body. This improves the long-term operational reliability of the scroll compressor.

[0109] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: By providing an oil inlet channel 61, a connecting channel 62, and an oil outlet channel 63, metal shavings generated by the wear between at least a part of the crankshaft structure 40 and the stop member 30 during compressor operation can be discharged along the oil inlet channel 61, the connecting channel 62, and the oil outlet channel 63 to the bottom of the lower cover 84 of the housing 80 using lubricating oil as a medium. These shavings are then attracted to a magnet fixed at the lower cover 84, thus preventing metal shavings from remaining inside the filter chamber 21 of the filter element 20 and affecting the normal operation of the hydraulic pump 50. This also prevents metal shavings impurities from being drawn into the hydraulic pump 50 after depositing in the filter chamber 21 of the filter element 20, reducing the probability of blockage or jamming of the hydraulic pump 50, and ensuring long-term stable operation of the hydraulic pump 50, pumping efficiency, and long-term reliability of the scroll compressor. This ensures a long-term stable and efficient oil supply from the hydraulic pump 50 to the pump body components of the compressor, improving the reliability of existing scroll compressor operation. The above embodiments solve the problem of metal filings remaining in the filter chamber 21 and being unable to be removed, and solve the problem of metal filings entering the oil pump and blocking the oil flow path, affecting the oil pump's oil supply efficiency.
