Description

Technical Field

[0001] This invention relates to the field of compressor technology, specifically to a compressor support structure, a compressor, and an air conditioner. Background Technology

[0002] Scroll compressors are characterized by their simple structure, small size, light weight, low noise, high mechanical efficiency, and stable operation. For compressors with a bottom thrust shaft structure, under the influence of their own weight and the downward magnetic pull of the motor, the lower end face of the oil pump drive head of the shaft assembly generates rotational friction with the thrust plate. However, when the perpendicularity between the center of the shaft assembly and the thrust plate is poor, uneven wear occurs between the lower end face of the drive head and the thrust plate, thus affecting the reliability of the compressor.

[0003] To solve the problem of uneven wear between the lower end face of the drive head and the thrust plate, a common solution is to improve the assembly accuracy of the shaft system and the upper and lower supports. However, it is still difficult to solve the problem of uneven wear.

[0004] Because existing scroll compressors suffer from technical problems such as uneven wear between the lower end face of the oil pump drive head and the thrust plate in the shaft assembly, this invention studies and designs a compressor support structure, a compressor, and an air conditioner. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of uneven wear between the lower end face of the oil pump drive head of the shaft assembly and the thrust plate in the existing scroll compressor, thereby providing a support structure for the compressor, the compressor, and the air conditioner.

[0006] To address the above problems, the present invention provides a support structure for a compressor, comprising:

[0007] The compressor includes a drive component, a thrust member, and an oil pump. The drive component is connectable to the crankshaft of the compressor and can be driven to rotate by the crankshaft. The drive component has a downward-facing first end face, and the thrust member has an upward-facing second end face. Both the first and second end faces are planar and fit together to form an upward support of the drive component by the thrust member.

[0008] The thrust member also has a downward-facing third surface, and the oil pump has an upward-facing fourth surface. One of the third and fourth surfaces is an outwardly convex arc surface, and the other is an inwardly concave arc surface. The outwardly convex arc surface and the inwardly concave arc surface can be fitted together. When the crankshaft tilts, the second end face can still maintain its fitted position with the first end face and deflect as a whole. The third surface can adaptively deflect relative to the fourth surface and still maintain its fitted position with the fourth surface.

[0009] In some implementations...

[0010] The thrust member has a first arc-shaped protrusion facing downwards, and the oil pump has a first arc-shaped groove facing upwards. The first arc-shaped protrusion can be configured to cooperate with the first arc-shaped groove. The third surface is the outer convex arc surface of the first arc-shaped protrusion, and the fourth surface is the inner concave arc surface of the first arc-shaped groove. When the crankshaft tilts, the first arc-shaped protrusion can adaptively deflect in the first arc-shaped groove, and can still maintain the fit between the outer convex arc surface of the first arc-shaped protrusion and the inner concave arc surface of the first arc-shaped groove.

[0011] In some implementations...

[0012] The thrust member has a downward-facing second arc-shaped groove, and the oil pump has an upward-facing second arc-shaped protrusion. The second arc-shaped protrusion can be configured to cooperate with the second arc-shaped groove. The third surface is the inner concave arc surface of the second arc-shaped groove, and the fourth surface is the outer convex arc surface of the second arc-shaped protrusion. When the crankshaft tilts, the second arc-shaped protrusion can adaptively deflect in the second arc-shaped groove, and can still maintain the fit between the outer convex arc surface of the second arc-shaped protrusion and the inner concave arc surface of the second arc-shaped groove.

The first connecting hole and the second connecting hole are axially opposite each other and are simultaneously inserted into the first connecting hole and the second connecting hole by fasteners, so as to fix the oil pump to the lower bracket. The outer periphery of the plate-like structure is provided with a through groove penetrating its upper and lower end faces. The through groove is formed as a notch structure. The fasteners can pass through the through groove to limit the plate-like structure circumferentially and radially, but allow the thrust member to tilt up and down.

[0019] In some implementations...

[0020] There are multiple first connecting holes, which are spaced apart on the oil pump in the circumferential direction. There are also multiple second connecting holes, which are spaced apart on the lower bracket in the circumferential direction.

The fasteners are set in a one-to-one correspondence with the first connecting holes.

[0021] In some implementations...

[0028] A first oil guide groove is also provided on the second end face of the plate-like structure, and a second oil guide groove is also provided on the third face.

[0029] In some implementations...

[0030] The plate-like structure is an annular structure with a shaft hole.

The shape of the first oil guide groove in the cross section perpendicular to its extension direction is a "V" shape.

[0031] In some implementations...

[0032] The drive component includes a first shaft segment structure located at the lower end of the first end face. The first shaft segment structure can pass through the thrust member and connect to the oil pump. The drive component also includes a second shaft segment structure located at the upper end of the first end face. The second shaft segment structure can pass through the interior of the central oil hole at the lower end of the crankshaft and be fixed to the crankshaft. The drive component can be driven to rotate as a whole by the crankshaft, thereby drawing oil from the oil sump below into the central oil hole through the oil pump.

[0036] This invention features a thrust member with an upward-facing, flat second end face and a drive member with a downward-facing, flat first end face. The first and second end faces are planarly fitted together, with the second end face providing support for the drive member. Furthermore, the third and fourth end faces—one a convex arc surface and the other a concave arc surface—are effectively fitted together. Therefore, when the crankshaft tilts, the drive member is deflected by the crankshaft, further causing the thrust member to deflect. Because the thrust member and oil pump are fitted together via arc surfaces, the thrust member can adaptively deflect. This allows for adaptive adjustment of the support angle between the thrust plate and the lower end face of the drive head as the shaft tilts, effectively preventing and reducing uneven wear between the lower end face of the drive and the thrust plate. This reduces frictional power consumption caused by uneven wear and improves the reliability of the compressor. Attached Figure Description

[0053] like Figures 1 to 7 As shown, the present invention provides a support structure for a compressor, which includes:

[0054] The compressor comprises a drive component 15, a thrust member 16, and an oil pump 7. The drive component 15 is connectable to the crankshaft of the compressor and can be driven to rotate by the crankshaft. The drive component 15 has a downward-facing first end face 151, and the thrust member 16 has an upward-facing second end face 161. Both the first end face 151 and the second end face 161 are planar and fit together to form an upward support of the drive component 15 by the thrust member 16.

[0055] The thrust member 16 also has a downward-facing third surface, and the oil pump 7 has an upward-facing fourth surface. One of the third surface and the fourth surface is an outwardly convex arc surface, and the other is an inwardly concave arc surface. The outwardly convex arc surface and the inwardly concave arc surface can be fitted together. When the crankshaft tilts, the second end face 161 can still maintain its fitted position with the first end face 151 and deflect as a whole. The third surface can adaptively deflect relative to the fourth surface and still maintain its fitted position with the fourth surface.

[0056] This invention features a thrust member with a second, upward-facing planar end face and a drive member with a first, downward-facing planar end face. The first and second end faces are planarly fitted together, with the second end face providing support for the drive member. Furthermore, the third and fourth surfaces—one a convex arc surface and the other a concave arc surface—are effectively fitted together. Therefore, when the crankshaft tilts, the drive member is deflected by the crankshaft, further causing the thrust member to deflect. Because the thrust member and oil pump are fitted together via arc surfaces, the thrust member can adaptively deflect. This allows for adaptive adjustment of the support angle between the thrust plate and the lower end face of the drive head as the shaft tilts, effectively preventing and reducing uneven wear between the lower end face of the drive and the thrust plate. This reduces frictional power consumption caused by uneven wear and improves the reliability of the compressor.

[0057] To address the uneven wear problem in the background technology, this invention proposes a lower support structure with flexible thrust-resistant function. This invention employs a flexibly adjustable support angle between the thrust plate and the lower end face of the drive head to adapt to the shaft tilt, prevent uneven wear of the thrust plate, solve the uneven wear problem between the lower end face of the drive head and the thrust plate, and at the same time maintain the advantages of high efficiency and reliability of the compressor.

[0058] Example 1, as Figure 1-4 As shown, in some implementations,

[0059] The thrust member 16 has a downward-facing first arcuate protrusion 162, and the oil pump 7 has an upward-facing first arcuate groove 701. The first arcuate protrusion 162 can be fitted with the first arcuate groove 701. The third surface is the outer convex arcuate surface of the first arcuate protrusion 162, and the fourth surface is the inner concave arcuate surface of the first arcuate groove 701. When the crankshaft tilts, the first arcuate protrusion 162 can adaptively deflect in the first arcuate groove 701, and can still maintain the fit between the outer convex arcuate surface of the first arcuate protrusion 162 and the inner concave arcuate surface of the first arcuate groove 701.

[0060] This is a preferred structural form of Embodiment 1 of the present invention, wherein the thrust member forms a first arc-shaped protrusion facing downward, the third surface is the outer convex arc surface of the first arc-shaped protrusion, the oil pump forms a first arc-shaped groove facing upward, and the fourth surface is the inner concave arc surface of the first arc-shaped groove. This allows the first arc-shaped protrusion and the first arc-shaped groove to form a concave-convex arc surface fit, so that the thrust member can be driven by the drive member to deflect up and down when the shaft system is tilted. The concave-convex arc surface enables adaptive adjustment of the support angle, so that the thrust member always maintains planar support for the drive member, reduces the wear between the lower end face of the drive and the thrust plate, improves the operating reliability of the compressor, reduces power consumption, and improves energy efficiency.

[0061] Example 2, as Figure 5-7 As shown, in some implementations,

[0062] The thrust-stop component 16 has a downward-facing second arcuate groove 182, and the oil pump 7 has an upward-facing second arcuate protrusion 701'. The second arcuate protrusion 701' can be configured to cooperate with the second arcuate groove 182. The third surface is the inner concave arcuate surface of the second arcuate groove 182, and the fourth surface is the outer convex arcuate surface of the second arcuate protrusion 701'. When the crankshaft tilts, the second arcuate protrusion 701' can adaptively deflect in the second arcuate groove 182, and can still maintain the fit between the outer convex arcuate surface of the second arcuate protrusion 701' and the inner concave arcuate surface of the second arcuate groove 182.

[0063] This is a preferred structural form of Embodiment 2 of the present invention, wherein the thrust member forms a second arc-shaped groove facing downward, the third surface is the inner concave arc surface of the second arc-shaped groove, the oil pump forms a second arc-shaped protrusion facing upward, and the fourth surface is the outer convex arc surface of the second arc-shaped protrusion. This allows the second arc-shaped protrusion and the second arc-shaped groove to form a concave-convex arc surface fit, so that the thrust member can be driven by the drive member to deflect up and down when the shaft system is tilted. The concave-convex arc surface enables adaptive adjustment of the support angle, so that the thrust member always maintains planar support for the drive member, reduces the wear between the lower end face of the drive and the thrust plate, improves the operating reliability of the compressor, reduces power consumption, and improves energy efficiency.

[0064] In some implementations...

[0065] Both the convex and concave arc surfaces are spherical structures; and / or the thrust member 16 is an elastic structure made of elastic material or a flexible structure made of flexible material.

[0066] This is a further preferred structural form of the convex and concave arc surfaces of the present invention. The spherical structure enables better surface mating in three-dimensional space, increases the contact area between the convex and concave arc surfaces, further enhances the ability to adaptively adjust the support angle, and further improves the anti-wear performance. The thrust-stopping component of the present invention is preferably made of elastic material or flexible material, which can generate a certain elastic or flexible deformation during the compression process between its upper end and the driving component, further enhancing the contact area between the lower arc surface structure and the oil pump arc surface, and further improving the anti-wear performance.

[0067] In some implementations...

[0068] It also includes a lower bracket 8, which is disposed on the outer periphery of the crankshaft 10, and the oil pump 7 can be fixed to the lower bracket 8; the thrust member 16 includes a plate-like structure 160, which is located between the oil pump 7 and the lower bracket 8 so as to be limited, the upper end face of the plate-like structure 160 forms the second end face 161, and the lower end of the plate-like structure 160 is connected to the third face.

[0069] The present invention also enables effective fixation of the oil pump by setting the lower bracket, and the thrust member is set between the lower bracket and the oil pump to effectively limit the movement. The upper end face of the plate structure forms a second end face that can support the first end face of the drive component, thereby connecting with the drive component to provide planar fit support capability. The lower end of the plate structure can connect to a third surface, that is, the lower end face of the plate structure can connect to, for example, the first arc surface protrusion of Embodiment 1, or to, for example, the second arc surface groove structure of Embodiment 2, to transmit force and torque, and to adaptively deflect a certain angle through the arc surface mating structure according to the inclination of the shaft system, so as to ensure that the second end face and the first end face of the drive component always maintain a planar fit support performance, further reducing and preventing uneven wear.

[0070] In some implementations...

[0071] The oil pump 7 is provided with a first connecting hole, and the lower bracket 8 is provided with a second connecting hole. The first connecting hole and the second connecting hole are axially opposite each other and are simultaneously inserted into the first connecting hole and the second connecting hole by fastener 17, so as to fix the oil pump 7 to the lower bracket 8. The outer periphery of the plate structure 160 is provided with a through groove 164 penetrating its upper and lower end faces. The through groove 164 is formed as a notch structure. The fastener 17 can pass through the through groove 164 to limit the plate structure 160 circumferentially and radially, but allows the thrust member 16 to tilt up and down or rotate.

[0072] The present invention also fixes the oil pump and the lower bracket together as a whole through the first connecting hole of the oil pump, the second connecting hole of the lower bracket, and fasteners. The plate structure has through grooves on its outer periphery, which are opposite to the first and second connecting holes. The fasteners can also limit the plate structure to a certain extent, such as limiting the circumferential rotation of the plate structure, but allow the thrust member to tilt up and down or rotate. This allows the deflection angle of the thrust member to be adaptively adjusted according to the tilt of the shaft system in the vertical direction, maintaining the upper end face of the thrust member in a constant surface contact with the drive member, thus improving the anti-wear performance.

[0073] In some implementations...

[0074] There are multiple first connecting holes, which are spaced apart in the circumferential direction on the oil pump 7. There are also multiple second connecting holes, which are spaced apart in the circumferential direction on the lower bracket 8. There are multiple through slots 164, which are spaced apart in the circumferential direction on the thrust member 16. There are also multiple fasteners. The first connecting holes and the second connecting holes are set one-to-one, the through slots 164 are also set one-to-one with the first connecting holes, and the fasteners are set one-to-one with the first connecting holes.

[0075] The present invention, through the one-to-one arrangement of multiple first connecting holes, multiple second connecting holes, multiple through slots, and multiple fasteners, can further improve the tightness between the oil pump and the lower support, and further improve the limiting ability of the thrust component.

[0078] This is a preferred structural form of Embodiment 1 of the present invention, wherein a gap △1 is formed between the upper end face of the thrust member and the lower support, ensuring that the thrust member has a certain amount of room for movement at the upper end, providing conditions for adaptive deflection according to the tilt of the shaft system; and a gap △2 is formed between the lower end face of the thrust member and the oil pump, ensuring that the thrust member has a certain amount of room for movement at the lower end, providing conditions for adaptive deflection according to the tilt of the shaft system.

[0080] This is a preferred structural form of Embodiment 2 of the present invention, namely, a gap △3 can be formed between the upper end face of the thrust member and the lower support to ensure that the thrust member has a certain amount of room for movement at the upper end, providing conditions for adaptive deflection according to the tilt of the shaft system; a gap △4 can be formed between the lower end face of the thrust member and the oil pump to ensure that the thrust member has a certain amount of room for movement at the lower end, providing conditions for adaptive deflection according to the tilt of the shaft system; and a certain amount of room △5 can also be formed between the upper end of the oil pump and the lower end face of the plate-like structure of the thrust member, providing conditions for adaptive deflection according to the tilt of the shaft system.

[0081] In some implementations...

[0082] When the thrust member 16 has a downward-facing first arcuate protrusion 162 and the oil pump 7 has an upward-facing first arcuate groove 701: △1 satisfies 0.5~1.0mm; △2 satisfies 0.5~1.0mm;

The lower end face (first end face 151) of the drive head rests on the upper end face (second end face 161) of the thrust plate (thrust component 16) under the action of the shaft system gravity and the downward magnetic pull of the motor. The lower end structure of the thrust component 16 is designed as a spherical structure (first arc surface protrusion 162). The first arc surface protrusion 162 cooperates with the spherical groove (first arc surface groove 701) of the oil pump 7. The first arc surface protrusion 162 of the thrust component 16 can automatically adjust the fitting angle according to the tilt angle of the lower end face of the drive component 15. The oil pump 7 is fixed to the lower end of the lower bracket 8 by screws.

[0086] The first upper end face 702 of the oil pump 7 is tightly fitted to the fourth lower end face 801 of the lower bracket 8. In the axial space, the second end face 161 of the thrust member 16 has a gap of Δ1 with the first lower end face 802 of the lower bracket 8, which is approximately 0.5–1.0 mm. Furthermore, the second lower end face 165 of the thrust member 16 has a gap of Δ2 with the first upper end face 702 of the oil pump 7, which is also approximately 0.5–1.0 mm. This allows the thrust member 16 to be flexibly adjusted within this space. Figure 3 As shown in the assembly diagram, the screw passes through the through slot 164 of the thrust member 16, thereby preventing the thrust member 16 from rotating, but retaining circumferential rotation space.

[0087] like Figure 4 As shown, a V-shaped first oil guide groove 166 is provided on the upper end face of the thrust member 16, and a second oil guide groove 163 is provided on the outer circle of the first arc surface protrusion 162, thereby ensuring oil lubrication of the friction surface and the assembly surface.

[0088] During compressor operation, the crankshaft assembly has a certain tilt angle due to assembly. At this time, the thrust member 16 of the present invention can flexibly adjust the support angle between the second end face 161 of the thrust member 16 and the first end face 151 of the drive member 15 to adapt to the shaft tilt, prevent the thrust member 16 from wearing off, and improve the reliability of the compressor.

[0089] Example 2, as Figure 5 , 6As shown in Figure 7, which is a partial structural schematic diagram of Embodiment 2 of the present invention, an oil pump drive component 15 is installed at the lower end of the crankshaft 10. The lower end face (first end face 151) of the drive component 15 rests on the upper end face (second end face 161) of the thrust component 16 under the action of the shaft gravity and the downward magnetic pull of the motor. The lower end structure of the thrust component 16 is designed as a spherical groove (second arc surface groove 182). The second arc surface groove 182 cooperates with the spherical body (second arc surface protrusion 701') of the oil pump 7. The second arc surface groove 182 of the thrust component 16 can automatically adjust the fitting angle according to the tilt angle of the lower end face of the drive component 15. The oil pump 7 is fixed to the lower end of the lower bracket 8 by screws. In the space on the shaft, the second end face 161 of the thrust member 16 has a gap of Δ3 with the first lower end face 802 of the lower support 8, which is approximately 0.5 to 1.0 mm; the second lower end face 165 of the thrust member 16 has a gap of Δ5 with the first upper end face 702 of the oil pump 7, which is approximately 0.5 to 1.0 mm; and the third lower end face 184 of the thrust member 16 has a gap of Δ4 with the second upper end face 703 of the oil pump 7, which is approximately 0.5 to 1.0 mm. Thus, the thrust member 16 can be flexibly adjusted within this space. Figure 6 As shown in the assembly diagram, the screw passes through the through slot 164 of the thrust member 16, thereby preventing the thrust member 16 from rotating, but retaining circumferential rotation space. Figure 7 As shown, a V-shaped first oil guide groove 166 is provided on the upper end face of the thrust member 16, and a second oil guide groove 163 is provided on the inner peripheral wall of the second arc-shaped groove 182, thereby ensuring oil lubrication of the friction surface and the assembly surface.

[0090] In some implementations...

[0091] A first oil guide groove 166 is also provided on the second end face 161 of the plate structure 160, and a second oil guide groove 163 is also provided on the third surface.

[0092] The present invention also provides a certain lubrication effect between the second end face of the plate structure and the first end face of the driving component through the first guide groove, thereby further reducing the wear between the thrust component and the driving component; and provides a certain lubrication effect during the cooperation between the convex arc surface and the concave arc surface through the second oil guide groove on the third surface, thereby further ensuring that the deflection angle of the thrust component can be smoothly and adaptively changed, and improving the anti-wear performance.

[0093] In some implementations...

[0094] The plate-like structure 160 is an annular structure with a shaft hole. One end of the first oil guide groove 166 is connected to the shaft hole of the plate-like structure 160, and the other end extends to the radial outer periphery of the plate-like structure 160. There are at least two first oil guide grooves 166, and the at least two first oil guide grooves 166 are spaced apart in the circumferential direction. The second oil guide groove 163 is an annular groove structure. The shape of the first oil guide groove 166 in the cross-section perpendicular to its extension direction is a "V" shape.

[0095] This is a further preferred structural form of the plate-like structure, the first oil guide groove, and the second oil guide groove of the present invention. The multiple spaced first oil guide grooves can increase the lubrication area, improve the lubrication performance between the thrust member and the drive member, and further prevent uneven wear. The annular groove of the second oil guide groove can also further increase the lubrication area between the convex arc surface and the concave arc surface, and improve the ability to adaptively change the deflection angle of the thrust member. The "V" shaped first oil guide groove can store more lubricating oil, which can further improve the lubrication capacity and the ability to prevent uneven wear.

[0096] In some implementations...

[0097] The drive component 15 includes a first shaft segment structure located at the lower end of the first end face 151. The first shaft segment structure can pass through the thrust member 16 and be connected to the oil pump 7. The drive component 15 also includes a second shaft segment structure located at the upper end of the first end face 151. The second shaft segment structure can pass through the interior of the central oil hole at the lower end of the crankshaft 10 and be fixed to the crankshaft 10. The drive component 15 can be driven to rotate as a whole by the crankshaft 10, and then the oil pump 7 draws oil from the oil pool below into the central oil hole.

[0098] This is a preferred structural form of the drive component of the present invention. The lower end of its first end face is connected to the thrust member and supported by the thrust member. The upper part of the first end face of the drive component is inserted into the central oil hole of the crankshaft to fix the crankshaft and the drive component as a whole. The drive component has a hollow oil hole inside, which can realize the performance of oil supply and guidance to the inside of the crankshaft. The first shaft section structure at the lower end of the first end face can be connected to the oil pump so that the lubricating oil can be drawn by the oil pump.

[0099] The present invention also provides a compressor (preferably a scroll compressor) that includes the aforementioned support structure of the compressor.

[0100] like Figure 1As shown, the scroll compressor mainly consists of a motor 4, an upper bracket 3, a lower bracket 8, a stationary scroll 1, a moving scroll 2, a cross slip ring 12, and a crankshaft 10. The motor 4 is fixed to the housing 5 by a heat-shrink fitting, and the upper bracket 3 is fixed to the housing 5 by spot welding. The moving scroll 2 and the stationary scroll 1 are mounted opposite each other on the upper bracket 3 with a phase angle difference of 180 degrees. Driven by the crankshaft 10, the moving scroll 2 moves and meshes with the stationary scroll 1 to form a series of mutually isolated, continuously varying crescent-shaped sealed cavities. The stationary scroll 1 is fixed to the upper bracket 3 by screw fasteners. The lower bracket 8 is fixed to the lower support ring 11 by screws, and the lower support ring 11 is then fixed to the housing 5 by spot welding.

[0101] When the compressor is running, the motor 4 drives the crankshaft 10 to rotate. The crank of the crankshaft 10 drives the moving scroll 2 to move. Under the anti-rotation restriction of the cross slip ring 12, the moving scroll 2 performs translational motion around the center of the crankshaft 10 with a fixed radius. The refrigerant entering from the suction pipe 14 is drawn into the crescent-shaped suction chamber formed by the moving scroll 2 and the stationary scroll 1. After being compressed, it is discharged from the exhaust port of the stationary scroll 1 and enters the cavity between the upper cover 13 and the stationary scroll 1. Then, it enters the cavity between the upper support 3 and the motor 4 through the exhaust groove of the stationary scroll 1 and the upper bracket 3. Part of it enters the lower end of the motor 4 through the flow groove between the motor 4 and the housing 5. Finally, the high-pressure exhaust refrigerant is discharged through the exhaust pipe.

[0102] The present invention also provides an air conditioner that includes the aforementioned compressor.

[0103] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
