Abstract
Description
Technical Field
[0001] This utility model relates to the field of compressor technology, and in particular to a support component and a compressor containing the same. Background Technology
[0002] With the development of compressor technology and the increasing demands for high efficiency, the motor speed of rotary compressors is getting higher and higher. When the compressor operates at high speed, the high-frequency pulsations caused by the compression of refrigerant within the cylinder are transmitted through the shaft, leading to rotor eccentricity. This significantly increases the compressor's vibration and noise, affecting the stability of the equipment. Simultaneously, high-speed operation causes internal compressor components to experience higher mechanical stress, increasing wear and fatigue, and shortening the equipment's lifespan. Utility Model Content
[0003] The purpose of this utility model is to provide a support component and a compressor containing it, so as to solve the technical problems of high vibration and noise at high speed and poor assembly coaxiality of compressors in the prior art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a support assembly, including a support body adapted to the shape of the compressor's inner cavity, and further including a buffer structure, a connecting structure, and a flow hole; wherein: The buffer structure is disposed within the supporting body to absorb kinetic energy; The connection structure is located on the side of the support body near the stator assembly and is detachably connected to the frame in the stator assembly. The flow hole is formed through the support body to achieve passage on both sides.
[0005] The support assembly of this utility model has its support body installed in the compressor cavity with a zero-clearance fit, equivalent to three-point welding, which can improve the coaxiality with the casing and the parallelism with the flange. By setting a buffer structure on the support body, similar to the principle of a spring, kinetic energy is absorbed, reducing the vibration transmitted to the edge, reducing vibration transmission, and allowing less vibration to be transmitted to the casing, thereby improving operational stability. The buffer structure can buffer relatively severe vibrations at low frequencies, and can improve the rigidity and stability of the shaft at high frequencies, reduce vibration amplitude, and reduce noise. By connecting the structure with the frame in the stator assembly, the coaxiality of the casing, stator, and support structure is improved.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] As a further improvement of this utility model, the number of flow holes is three, which are spaced apart along the circumferential direction of the support body.
[0008] This utility model provides a flow hole, which allows the two sides of the support body to be connected for refrigerant flow. By providing multiple flow holes, the flow area is maximized while ensuring structural rigidity, reducing the number of refrigerant flow components, and facilitating the passage of motor leads.
[0009] As a further improvement of this utility model, the number of buffer structures is three, which are arranged between two adjacent flow holes.
[0010] This invention achieves uniform fluid distribution and pressure balance by placing a buffer structure between two adjacent flow holes, while also enhancing the symmetry and stability of the structure and preventing functional failure.
[0011] As a further improvement of this utility model, the buffer structure is located in the middle of the flow hole.
[0012] As a further improvement of this utility model, the flow hole has an elliptical structure and a chamfered structure at the edge.
[0013] This utility model has three flow holes with an angle difference of 120°, presenting an elliptical shape. While ensuring structural rigidity, it maximizes the flow area. The edges are chamfered to reduce refrigerant flow resistance and facilitate the passage of motor lead wires (the lead wire connector is connected to the power connector on the top cover).
[0014] As a further improvement of this utility model, the buffer structure has an N-shaped main cross-section, including a first buffer section, a second buffer section, and a third buffer section; wherein: The first buffer portion extends obliquely upward from the bottom surface of the support body, and its top protrudes from the top surface of the support body; One end of the third buffer section extends obliquely downward from the top surface of the support body, and the other end protrudes from the bottom surface of the support body. One end of the second buffer is connected to the top of the first buffer, and the other end extends below the bottom of the support body and is connected to the top of the third buffer.
[0015] As a further improvement of this utility model, the thickness of the second buffer part is less than the thickness of the first buffer part, and the thickness of the first buffer part is equal to the thickness of the third buffer part.
[0016] The N-shaped buffer structure of this invention is thick on both sides and thin in the middle. The purpose is to control the deformation area. The thinner part in the middle is more likely to undergo plastic deformation under stress, thereby absorbing energy through material deformation. The thicker parts on both sides ensure the overall stability of the structure. It can absorb large vibrations at low frequencies and provide a certain rigidity at high frequencies. They are evenly distributed between the three flow holes and designed in the middle position to achieve uniform fluid distribution and pressure balance, while enhancing the symmetry and stability of the structure and preventing functional failure.
[0017] As a further improvement of this utility model, the corners of the buffer structure are all rounded transition structures.
[0018] As a further improvement of this utility model, the connecting structure includes a plurality of buckles evenly arranged along the circumference of the supporting body.
[0019] As a further improvement of this utility model, the number of buckles is three.
[0020] This utility model has three bottom clips with an angle difference of 120° and a thickness of 1mm. The inner diameter is consistent with the outer diameter of the frame in the stator assembly. During installation, they fit tightly with the stator frame to ensure the coaxiality of the stator assembly and the support structure.
[0021] As a further improvement of this utility model, the top of the support body is recessed downward to form a storage groove; and / or, the middle part of the support body extends upward to form a sleeve shaft portion.
[0022] This utility model provides a compressor, comprising a housing, a stator assembly, a crankshaft, and the aforementioned support assembly; wherein: The stator assembly is housed within the housing; The support assembly is placed inside the housing and connected to the stator assembly; The top of the crankshaft passes through the stator assembly and connects to the support assembly.
[0023] The compressor of this invention improves the coaxiality with the housing and the parallelism with the flange by using a zero-clearance fit between the support body and the inner wall of the casing, which is equivalent to a three-point welding structure. The snap-fit mechanism with the frame in the stator assembly further improves the coaxiality of the housing, stator, and support structure. The buffer structure effectively cushions severe vibrations at low frequencies and improves shaft rigidity and stability at high frequencies, reducing vibration amplitude and noise. Furthermore, the simple-supported beam structure formed by the support assembly and the upper flange bearing is more stable than the traditional cantilever beam structure, reducing crankshaft bending during operation and extending the compressor's service life.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Example 1: like Figures 1-7 As shown, this utility model provides a support component 2, which is used to be installed at the end of the crankshaft 5 and together with the upper flange 7 bearing to form a structure similar to a simply supported beam. Specifically, the support component 2 includes a support body adapted to the shape of the compressor cavity. Since the compressor cavity is circular and the support component 2 needs to be fixed to the cavity, in this embodiment, the support body is a disc-shaped structure. The outer edge is in zero-clearance fit with the compressor cavity. It should be noted that the zero-clearance fit here means that the support body and the compressor cavity are in contact and connected, and the two can abut or fit together. After connection, no displacement will occur under the action of friction between the two, and stability will be maintained. It also includes a buffer structure 2.1, a connecting structure, and a flow hole 2.3; wherein: The buffer structure 2.1 is set in the supporting body to absorb kinetic energy; The connection structure is located on the side of the support body close to the stator assembly 4 and is detachably connected to the frame 4.1 in the stator assembly 4; The flow hole 2.3 is opened through the support body to achieve passage on both sides.
[0029] It should be noted that in this embodiment, the support body is made of steel. Of course, it can also be made of high rigidity and low weight materials to achieve both support structure and lightweight design.
[0030] The support assembly 2 of this utility model is installed in the compressor cavity with a zero-clearance fit, which is equivalent to three-point welding. This can improve the coaxiality with the housing 11 and the parallelism with the flange. By setting a buffer structure 2.1 on the support body, similar to the principle of a spring, kinetic energy is absorbed, reducing the vibration transmitted to the edge, reducing vibration transmission, and allowing less vibration to be transmitted to the housing 11, thereby improving the stability of operation. The buffer structure 2.1 can buffer relatively severe vibrations at low frequencies and improve the rigidity and stability of the shaft at high frequencies, reduce the vibration amplitude, and reduce noise. The connection structure cooperates with the frame 4.1 in the stator assembly 4 to improve the coaxiality of the housing, stator, and support structure.
[0031] As an optional embodiment of this utility model, such as Figure 6 and Figure 7As shown, there are three flow holes 2.3, which are spaced apart along the circumference of the support body.
[0032] like Figure 6 As shown, in this embodiment, the flow hole 2.3 has an elliptical structure with a chamfered edge. Of course, the structure of the flow hole 2.3 can be modified to better facilitate fluid flow.
[0033] The present invention has three flow holes 2.3, with an angle difference of 120°, presenting an elliptical shape. While ensuring structural rigidity, the flow area is maximized. The edges are chamfered to reduce refrigerant flow resistance and facilitate the passage of motor lead wires (lead wire connectors are connected to the power connector of the upper cover 1).
[0034] It should be noted that, in this embodiment, as Figure 6 and Figure 7 As shown, the flow hole 2.3 is relatively large, with its outer edge close to the outer edge of the support body and its inner edge close to the sleeve shaft 2.5. This structure maximizes the size of the flow hole 2.3, ensuring the strength of the support body while achieving the largest flow area.
[0035] This utility model provides a flow hole 2.3, which allows the two sides of the support body to be connected for refrigerant flow. By providing multiple flow holes 2.3, the flow area is maximized while ensuring structural rigidity, reducing the number of refrigerant flow components, and facilitating the passage of motor lead wires.
[0036] Furthermore, such as Figure 6 As shown, there are three buffer structures 2.1, which are set between two adjacent flow holes 2.3.
[0037] This invention achieves uniform fluid distribution and pressure balance by placing a buffer structure 2.1 between two adjacent flow holes 2.3, while also enhancing the symmetry and stability of the structure and preventing functional failure.
[0038] In order to achieve uniform fluid distribution and pressure balance, enhance the symmetry and stability of the structure, and prevent functional failure, in this embodiment, the buffer structure 2.1 is located in the middle of the flow hole 2.3.
[0039] As a further improvement of this utility model, the buffer structure 2.1 has an N-shaped main cross-section, including a first buffer part 2.11, a second buffer part 2.12, and a third buffer part 2.13; wherein: The first buffer section 2.11 extends obliquely upward from the bottom surface of the support body, and its top protrudes from the top surface of the support body. The third buffer section 2.13 extends obliquely downward from the top surface of the support body at one end, and protrudes from the bottom surface of the support body at the other end; One end of the second buffer part 2.12 is connected to the top of the first buffer part 2.11, and the other end extends below the bottom of the support body and is connected to the top of the third buffer part 2.13.
[0040] As a further improvement of this utility model, the thickness of the second buffer part 2.12 is less than the thickness of the first buffer part 2.11, and the thickness of the first buffer part 2.11 is equal to the thickness of the third buffer part 2.13.
[0041] The N-shaped buffer structure 2.1 of this utility model is thick on both sides and thin in the middle. The purpose is to control the deformation area. The thinner part in the middle is more likely to undergo plastic deformation under stress, thereby absorbing energy through material deformation. The thicker parts on both sides ensure the overall stability of the structure. The overall structure is similar to the principle of a spring to absorb kinetic energy and reduce the vibration transmitted to the edges. It can absorb large vibrations at low frequencies and provide a certain rigidity at high frequencies. They are evenly distributed between the three flow holes 2.3 and designed in the middle position to achieve uniform fluid distribution and pressure balance, while enhancing the symmetry and stability of the structure and preventing functional failure.
[0042] As a further improvement of this utility model, the corners of the buffer structure 2.1 are all rounded transition structures.
[0043] As a further improvement of this utility model, the connecting structure includes a plurality of latches 2.2 evenly arranged along the circumference of the supporting body. In use, the latches 2.2 are engaged on the outside of the frame 4.1.
[0044] As a further improvement to this utility model, such as Figure 7 As shown, there are three buckles 2.2, and each buckle 2.2 has an arc-shaped cross-section, which matches the curvature of the outer wall of the skeleton 4.1.
[0045] The bottom buckle 2.2 of this utility model has three buckles with an angle difference of 120° and a thickness of 1mm. The inner diameter is consistent with the outer diameter of the frame 4.1 in the stator assembly 4. During installation, it fits tightly with the stator frame 4.1 to ensure the coaxiality of the stator assembly 4 and the support structure.
[0046] As a further improvement of this utility model, the top of the support body is recessed downward to form a storage tank 2.4; Furthermore, the middle of the support body extends upward to form a sleeve shaft portion 2.5. Of course, a bearing can also be installed in the middle of the support body to connect with the crankshaft 5, thereby improving the reliability of the connection.
[0047] The support component provided by this utility model can also integrate a vibration damping device to reduce vibration transmission, allowing less vibration to be transmitted to the housing 11 and improving operational stability.
[0048] The support body of this utility model adopts a zero-clearance fit, a snap-fit 2.2 and a buffer structure 2.1 to better improve the rigidity and stability of the shaft, reduce the bending of the crankshaft 5, reduce the vibration amplitude, improve coaxiality, and ensure the uniformity of the stator and rotor gap. Compared with the traditional structure, it improves the operating stability and efficiency of the compressor, reduces vibration and noise, not only extends the service life of the equipment, but also reduces operating costs, which meets the requirements of green manufacturing and sustainable development.
[0049] Example 2: like Figures 1-7 As shown, the compressor provided by this utility model includes a housing 11, a stator assembly 4, a crankshaft 5, and a support assembly 2; as Figure 1 and Figure 2 As shown, it also includes rotor assembly 3, upper cover 1, silencer 6, upper flange 7, cylinder 8, lower flange 9, lower cover 10, and separator (not labeled in the figure); wherein: The stator assembly 4 is housed within the housing 11; the stator assembly 4 includes a frame 4.1, a stator core 4.2, and winding coils 4.3. The support assembly 2 is connected to the frame 4.1.
[0050] The support assembly 2 is placed inside the housing 11, located between the motor and the upper cover 1, and is connected to the stator assembly 4; After passing through the stator assembly 4, the top of the crankshaft 5 connects to the support assembly 2.
[0051] In this embodiment, the support assembly 2 includes a support body adapted to the shape of the inner cavity of the housing 11. Since the inner cavity of the housing 11 is circular and the support assembly 2 needs to be fixed to the inner cavity, the support body is a disc-shaped structure in this embodiment. The outer edge is in zero-clearance fit with the inner cavity of the compressor. It should be noted that the zero-clearance fit referred to here means that the support body is in contact with the inner wall of the housing 11, and the two can abut or fit together. After connection, no displacement will occur under the action of friction between the two, and stability will be maintained. The inner diameter of the support body matches the outer diameter of the crankshaft 5, and the outer diameter of the support body matches the inner diameter of the housing 11; the inner diameter of the support body is consistent with the inner diameter of the upper flange 7, and the outer diameter is consistent with the outer diameter of the stator assembly. It also includes a buffer structure 2.1, a connecting structure, and a flow hole 2.3; wherein: The buffer structure 2.1 is set in the supporting body to absorb kinetic energy; The connection structure is located on the side of the support body close to the stator assembly 4 and is detachably connected to the frame 4.1 in the stator assembly 4; The flow hole 2.3 is opened through the support body to achieve passage on both sides.
[0052] It should be noted that in this embodiment, the support body can be made of a high-rigidity, low-weight material to achieve both structural support and lightweight design.
[0053] The support assembly 2 of this utility model is installed in the compressor cavity with a zero-clearance fit, which is equivalent to three-point welding. This can improve the coaxiality with the housing 11 and the parallelism with the flange. By setting a buffer structure 2.1 on the support body, similar to the principle of a spring, kinetic energy is absorbed, reducing the vibration transmitted to the edge, reducing vibration transmission, and allowing less vibration to be transmitted to the housing 11, thereby improving the stability of operation. The buffer structure 2.1 can buffer relatively severe vibrations at low frequencies and improve the rigidity and stability of the shaft at high frequencies, reduce the vibration amplitude, and reduce noise. The connection structure cooperates with the frame 4.1 in the stator assembly 4 to improve the coaxiality of the housing, stator, and support structure.
[0054] As an optional embodiment of this utility model, such as Figure 6 and Figure 7 As shown, there are three flow holes 2.3, which are spaced apart along the circumference of the support body.
[0055] like Figure 6 As shown, in this embodiment, the flow hole 2.3 has an elliptical structure with a chamfered edge. Of course, the structure of the flow hole 2.3 can be modified to better facilitate fluid flow.
[0056] The present invention has three flow holes 2.3, with an angle difference of 120°, presenting an elliptical shape. While ensuring structural rigidity, the flow area is maximized. The edges are chamfered to reduce refrigerant flow resistance and facilitate the passage of motor lead wires (lead wire connectors are connected to the power connector of the upper cover 1).
[0057] It should be noted that, in this embodiment, as Figure 6 and Figure 7 As shown, the flow hole 2.3 is relatively large, with its outer edge close to the outer edge of the support body and its inner edge close to the sleeve shaft 2.5. This structure maximizes the size of the flow hole 2.3, ensuring the strength of the support body while achieving the largest flow area.
[0058] This utility model provides a flow hole 2.3, which allows the two sides of the support body to be connected for refrigerant flow. By providing multiple flow holes 2.3, the flow area is maximized while ensuring structural rigidity, reducing the number of refrigerant flow components, and facilitating the passage of motor lead wires.
[0059] Furthermore, such as Figure 6 As shown, there are three buffer structures 2.1, which are set between two adjacent flow holes 2.3.
[0060] This invention achieves uniform fluid distribution and pressure balance by placing a buffer structure 2.1 between two adjacent flow holes 2.3, while also enhancing the symmetry and stability of the structure and preventing functional failure.
[0061] In order to achieve uniform fluid distribution and pressure balance, enhance the symmetry and stability of the structure, and prevent functional failure, in this embodiment, the buffer structure 2.1 is located in the middle of the flow hole 2.3.
[0062] As a further improvement of this utility model, the buffer structure 2.1 has an N-shaped main cross-section, including a first buffer part 2.11, a second buffer part 2.12, and a third buffer part 2.13; wherein: The first buffer section 2.11 extends obliquely upward from the bottom surface of the support body, and its top protrudes from the top surface of the support body. The third buffer section 2.13 extends obliquely downward from the top surface of the support body at one end, and protrudes from the bottom surface of the support body at the other end; One end of the second buffer part 2.12 is connected to the top of the first buffer part 2.11, and the other end extends below the bottom of the support body and is connected to the top of the third buffer part 2.13.
[0063] As a further improvement of this utility model, the thickness of the second buffer part 2.12 is less than the thickness of the first buffer part 2.11, and the thickness of the first buffer part 2.11 is equal to the thickness of the third buffer part 2.13.
[0064] The N-shaped buffer structure 2.1 of this utility model is thick on both sides and thin in the middle. The purpose is to control the deformation area. The thinner part in the middle is more likely to undergo plastic deformation under stress, thereby absorbing energy through material deformation. The thicker parts on both sides ensure the overall stability of the structure. The overall structure is similar to the principle of a spring to absorb kinetic energy and reduce the vibration transmitted to the edges. It can absorb large vibrations at low frequencies and provide a certain rigidity at high frequencies. They are evenly distributed between the three flow holes 2.3 and designed in the middle position to achieve uniform fluid distribution and pressure balance, while enhancing the symmetry and stability of the structure and preventing functional failure.
[0065] As a further improvement of this utility model, the corners of the buffer structure 2.1 are all rounded transition structures.
[0066] As a further improvement of this utility model, the connecting structure includes a plurality of latches 2.2 evenly arranged along the circumference of the supporting body. In use, the latches 2.2 are engaged on the outside of the frame 4.1.
[0067] As a further improvement to this utility model, such as Figure 7As shown, there are three buckles 2.2, and each buckle 2.2 has an arc-shaped cross-section, which matches the curvature of the outer wall of the skeleton 4.1.
[0068] The bottom buckle 2.2 of this utility model has three buckles with an angle difference of 120° and a thickness of 1mm. The inner diameter is consistent with the outer diameter of the frame 4.1 in the stator assembly 4. During installation, it fits tightly with the stator frame 4.1 to ensure the coaxiality of the stator assembly 4 and the support structure.
[0069] As a further improvement of this utility model, the top of the support body is recessed downward to form a storage tank 2.4; Furthermore, the middle of the support body extends upward to form a sleeve shaft portion 2.5. Of course, a bearing can also be installed in the middle of the support body to connect with the crankshaft 5, thereby improving the reliability of the connection.
[0070] The support component provided by this utility model can also integrate a vibration damping device to reduce vibration transmission, allowing less vibration to be transmitted to the housing 11 and improving operational stability.
[0071] During installation, before heat fitting the stator assembly 4 to the housing 11, the support assembly 2 is fixed to the stator assembly 4. The stator assembly 4 includes a stator core 4.2, winding coils 4.3, a bobbin 4.1, insulating paper, etc. The bobbin 4.1 is a high-temperature resistant plastic material, designed in an arched shape with chamfers and covering the outer diameter of the stator slot. The coaxiality with the stator core is ensured by inserting the buckles of the bobbin 4.1 into the slots of the stator core 4.2. The winding coils 4.3 are wound on the stator core 4.2 with the bobbin 4.1 secured. The chamfers of the bobbin 4.1 and the covering of the stator slots can prevent the winding coils 4.3 from being scratched during the winding process, thus improving the yield.
[0072] The fixing method mainly involves using a fixing fixture to support the bottom of the stator core 4.2 to secure the bottom of the stator assembly 4. After securing the bottom of the stator assembly 4, the three-point clips 2.2 at the bottom of the support assembly are engaged with the frame 4.1 at a suitable angle. This suitable angle refers to any angle that ensures the stator assembly leads pass through the elliptical holes of the support assembly without interference, locking the two parts together precisely without radial wobbling. Then, a fixture with a certain mass is pressed onto the top of the support assembly 4 to ensure it does not loosen during operation, forming a top-down structure (fixture - support assembly - frame 4.1 - stator assembly 4 - fixing fixture). At this point, the coaxiality of the support assembly and the stator assembly 4 remains consistent. Finally, the housing 11 is heated to a certain time according to process requirements, and then heat-fitted together with the stator assembly 4 and the support assembly at a suitable heat-fitting angle to form an assembly. It should be noted that the suitable angle in this paragraph refers to an angle that can both secure the frame 4.1 and allow the stator leads to pass through smoothly.
[0073] The compressor of this invention improves the coaxiality with the housing 11 and the parallelism with the flange by using a zero-clearance fit between the support body and the inner wall of the housing 11, which is equivalent to a three-point welding structure. The snap-fit 2.2 fits with the frame 4.1 in the stator assembly 4, improving the coaxiality of the housing, stator, and support structure. The buffer structure 2.1 can buffer relatively severe vibrations at low frequencies and improve the rigidity and stability of the shaft at high frequencies, reducing vibration amplitude and noise. The support assembly 2 and the upper flange 7 bearing form a simply supported beam structure, which is more stable than the traditional cantilever beam structure, reduces the bending of the crankshaft 5 during operation, and extends the service life of the compressor.
