Description

Technical Field

[0001] This utility model belongs to the field of motor manufacturing technology, specifically a stator assembly bracket module. Background Technology

[0002] With the continuous development of motor technology, especially the widespread application of high-power, large-diameter motors in wind power generation, rail transportation, and industrial drives, the stator support, as a key structural component supporting the stator core and windings, directly affects the overall performance, manufacturing process, and ease of transportation and installation of the motor. Traditional stator supports mostly adopt an integral structure, which, while possessing high structural rigidity and coaxiality, faces problems such as transportation difficulties, complex processing, and inconvenient assembly in large motor applications. Therefore, modular, split-type, or detachable modular stator supports have gradually become a research focus.

[0003] A search revealed a stator support and stator with publication number CN112003397B, published on December 27, 2022. This patent proposes a stator support for large-diameter motors. By dividing the stator ring into multiple fan-shaped segments along the circumference and coaxially mounting them to the outer periphery of a support assembly, each segment can be transported independently and then assembled on-site, effectively solving the problem of limited transportation for large-size stator supports. This solution achieves dimensional control through segmented design, improving transportation feasibility.

[0004] However, this technical solution still has significant shortcomings: First, the stator ring segments are only coaxially arranged on the support assembly, lacking a reliable axial and circumferential positioning and locking structure, which makes them prone to relative displacement during transportation and assembly, affecting the overall concentricity and structural stability; Second, the structure does not consider the electrical connection and heat dissipation channel integration between modules, making it difficult to meet the requirements of high power density motors for electromagnetic compatibility and temperature rise control; Third, the segmented stator ring segments still need to rely on the central support assembly for support, and the overall weight is not significantly reduced, and the support assembly itself may still exceed the transportation limits, failing to fully achieve the goal of "lightweight split transportation".

[0005] A search revealed a stator support, stator module, and modular stator, published on June 30, 2020, with publication number CN108471183B. This patent provides a stator support comprising a first flange, a central assembly, and a second flange, which, together with a detachably connectable stator module, forms a modular stator structure. During transportation, the stator support and stator module can be transported separately, significantly reducing the overall volume and weight, and improving protection and transportation efficiency.

[0006] However, this solution also has limitations: First, the connection between the stator module and the stator support relies on the detachable connection between the first connecting plate and the second connecting plate. The connection points are concentrated at both ends of the axial direction, resulting in a lack of effective support in the middle area. Under heavy load or vibration conditions, it is prone to bending deformation, affecting the uniformity of the air gap. Second, the structure does not have a quick positioning and locking mechanism between modules. Additional tooling is required for alignment during on-site assembly, which increases the difficulty and time cost of installation. Third, the solution does not integrate a cooling system or electrical lead channel, which cannot meet the requirements of modern high-efficiency motors for thermal management and wiring integration, thus limiting its application in high-performance motors.

[0007] The aforementioned problems indicate that while existing split or modular stator supports alleviate transportation difficulties to some extent, they still have significant shortcomings in terms of structural stability, ease of assembly, and functional integration. These shortcomings make it difficult to meet the future development needs of high-power, high-reliability, and intelligent motors for integrated stator support structures that are "easy to transport, quick to assemble, strong in support, and multifunctional." Therefore, this utility model provides a stator combination support module, aiming to overcome the defects of existing technologies such as unreliable connections, complex assembly, and limited functionality. It achieves a balance between modular transportation and high-strength integrated support, thereby improving the overall manufacturing and maintenance efficiency of the motor. Utility Model Content

[0008] This utility model relates to a stator assembly support module, including a support frame, modular connecting components, a positioning and locking unit, and an integrated functional module. The support frame is composed of multiple arc-shaped segmented parts, which are spliced ​​together circumferentially to form a ring structure, and adjacent arc-shaped segmented parts are fixed together by the modular connecting components; the positioning and locking unit is installed at both ends of the arc-shaped segmented parts to achieve dual positioning in the axial and circumferential directions; the integrated functional module is embedded in the internal cavity of the support frame to provide electrical lead channels and coolant flow paths.

[0009] Each arc-shaped segment of the support frame has reinforcing ribs on its inner wall. These ribs are radially distributed and welded to the outer wall of the arc-shaped segment to enhance overall rigidity. The mating surfaces of adjacent arc-shaped segments are designed as stepped mating surfaces, including radial and axial mating surfaces. The radial and axial mating surfaces are perpendicular to each other, ensuring high-precision coaxiality of the assembled arc-shaped segments.

[0010] The modular connection assembly includes a bolt group, locating pins, and sealing washers. The bolt group passes through the mating end faces of adjacent arc-shaped segments and is locked in place by nuts; the locating pins are embedded in pin holes on the radial mating surfaces of adjacent arc-shaped segments for precise positioning; the sealing washers are sandwiched between the axial mating surfaces to prevent external contaminants from entering the interior of the support frame.

[0011] The positioning and locking unit includes a locking ring, an adjusting screw, and elastic blocks. The locking ring is sleeved on the outer walls of both axial ends of the support frame. An annular groove is formed on the inner side of the locking ring, and an elastic block is embedded in the annular groove. One side of the elastic block contacts the inner wall of the locking ring, and the other side fits against the outer wall of the support frame. The adjusting screw passes through the locking ring and presses against the elastic block. By rotating the adjusting screw, the clamping force of the elastic block on the support frame is changed, thereby achieving dual locking in both the axial and circumferential directions.

[0012] The integrated functional module includes cooling pipes, electrical lead troughs, and a distribution plate. The cooling pipes are arranged radially along the support frame, with one end connected to an external cooling system and the other end connected to the distribution plate, which evenly distributes the coolant into the internal cavities of each arc-shaped segment. The electrical lead troughs are arranged axially along the support frame and have internal insulating partitions to isolate electrical leads of different voltage levels. The cooling pipes and electrical lead troughs are separated by a thermal insulation layer made of a low thermal conductivity material to reduce heat transfer between the coolant and the electrical leads.

[0013] Preferably, the outer wall of the arc-shaped segment is provided with lifting lugs, which are symmetrically distributed on both sides of the arc-shaped segment for lifting operations during transportation and assembly. The lifting lugs are welded to the outer wall of the arc-shaped segment, and have threaded holes inside for installing lifting eye bolts.

[0014] The bottom of the support frame is equipped with support feet, which are fixedly connected to the bottom surface of the support frame by bolts. Shock-absorbing pads made of rubber are installed at the bottom of the support feet to absorb vibrations generated during motor operation.

[0015] A filter is installed at the inlet end of the cooling pipe. The filter contains a filter screen to intercept impurities in the coolant. A maintenance port is provided on the outer shell of the filter, which is sealed with a threaded cap for easy periodic cleaning of the filter screen.

[0016] The outlet end of the electrical lead trough is equipped with a waterproof connector, and a sealing ring is provided on the inner wall of the waterproof connector to prevent external moisture from entering the electrical lead trough. The waterproof connector is connected to the outlet end of the electrical lead trough by threads, and an anti-loosening nut is provided on its exterior to enhance the reliability of the connection.

[0017] The technical advantages of this invention are as follows: Through modular design, the support frame is decomposed into multiple arc-shaped segments, and rapid assembly is achieved through modular connecting components, significantly reducing transportation difficulty and assembly complexity. The positioning and locking unit, through the synergistic action of the locking ring, adjusting screw, and elastic pressure block, provides reliable positioning and locking in the axial and circumferential directions, preventing relative displacement after assembly. The integrated functional module organically combines cooling pipes and electrical lead-in slots, meeting the heat dissipation and wiring requirements of high-performance motors and improving overall functionality. These technical means address the shortcomings of existing technologies in terms of structural stability, ease of assembly, and functional integration, providing an innovative solution for the design of stator supports for high-power motors.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] This utility model relates to a stator assembly support module, the structure of which includes a support frame 1, modular connecting components 3, positioning and locking units 4, and integrated functional modules 5. The support frame 1 is formed by multiple arc-shaped segmented pieces 2 spliced ​​circumferentially to form a ring structure. Adjacent arc-shaped segmented pieces 2 are fixedly connected by modular connecting components 3. The positioning and locking units 4 are installed at both axial ends of the arc-shaped segmented pieces 2 to provide dual axial and circumferential positioning. The integrated functional modules 5 are embedded in the internal cavity of the support frame 1 for arranging cooling pipes 19 and electrical lead-in grooves 20. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, the support frame 1 is a ring-shaped structure composed of multiple arc-shaped segmented components 2. Each arc-shaped segmented component 2 has reinforcing ribs 6 on its inner wall, which are radially distributed and welded to the outer wall of the arc-shaped segmented component 2. The reinforcing ribs 6 enhance the overall rigidity of the arc-shaped segmented components 2, thereby improving the structural stability of the entire support frame 1. The mating surfaces of adjacent arc-shaped segmented components 2 are designed as stepped mating surfaces 7, such as... Figure 2 As shown, the stepped mating surface 7 includes a radial mating surface 8 and an axial mating surface 9, which are perpendicular to each other. The mating of the radial mating surface 8 and the axial mating surface 9 ensures high-precision coaxiality of adjacent arc-shaped segment parts 2 during splicing, avoiding instability of the overall structure due to splicing errors. Symmetrical lifting lugs 24 are provided on the outer wall of the arc-shaped segment part 2. The lifting lugs 24 are welded to the outer wall of the arc-shaped segment part 2, and have threaded holes 25 inside for installing lifting eye bolts 26. The design of the lifting lugs 24 facilitates lifting operations during transportation and assembly, thereby improving construction efficiency.

[0027] Modular connecting component 3 is used to fix the connection relationship between adjacent arc-shaped segment components 2. For example... Figure 1 As shown, the modular connection assembly 3 includes a bolt group 10, a locating pin 11, and a sealing washer 12. The bolt group 10 passes through the mating end faces of adjacent arc-shaped segment pieces 2 and is locked in place by nuts 13. The locating pin 11 is embedded in the pin hole 14 on the radial contact surface 8 of the adjacent arc-shaped segment pieces 2 for precise positioning, ensuring the accurate position of the arc-shaped segment pieces 2 during splicing. The sealing washer 12 is sandwiched between the axial contact surfaces 9 to prevent external contaminants from entering the internal cavity of the support frame 1. The above connection method not only ensures a firm connection between adjacent arc-shaped segment pieces 2 but also provides good sealing performance, preventing the intrusion of external impurities.

[0028] The positioning and locking unit 4 is installed at both axial ends of the arc-shaped segment 2 to achieve dual positioning in both the axial and circumferential directions. For example... Figure 4As shown, the positioning and locking unit 4 includes a locking ring 15, an adjusting screw 16, and an elastic pressure block 17. The locking ring 15 is sleeved on the outer walls of both axial ends of the support frame 1, and an annular groove 18 is formed on its inner side, in which the elastic pressure block 17 is embedded. One side of the elastic pressure block 17 contacts the inner wall of the locking ring 15, and the other side fits against the outer wall of the support frame 1. The adjusting screw 16 passes through the locking ring 15 and presses against the elastic pressure block 17. By rotating the adjusting screw 16, the pressing force of the elastic pressure block 17 on the support frame 1 is changed, thereby achieving dual locking in both the axial and circumferential directions. This design, through the synergistic effect of the locking ring 15, the adjusting screw 16, and the elastic pressure block 17, effectively avoids relative displacement of the assembled arc-shaped segment 2, further improving the overall stability of the support frame 1.

[0029] The integrated functional module 5 is embedded in the internal cavity of the support frame 1, providing a coolant flow path and an electrical lead channel. For example... Figure 3 As shown, the integrated functional module 5 includes a cooling pipe 19, an electrical lead tray 20, and a distribution plate 21. The cooling pipe 19 is arranged radially along the support frame 1, with one end connected to an external cooling system and the other end connected to the distribution plate 21. The distribution plate 21 evenly distributes the coolant into the internal cavities of each arc-shaped segment 2, thereby achieving efficient heat dissipation. The electrical lead tray 20 is arranged axially along the support frame 1, and has an insulating partition 22 inside to isolate electrical leads of different voltage levels. The cooling pipe 19 and the electrical lead tray 20 are separated by a thermal insulation layer 23, which is made of a low thermal conductivity material to reduce heat transfer between the coolant and the electrical leads. This design organically combines the cooling pipe 19 and the electrical lead tray 20, meeting the heat dissipation and wiring requirements of high-performance motors.

[0030] A filter 30 is installed at the inlet end of the cooling pipe 19. The filter 30 contains a filter screen 31 to intercept impurities in the coolant. A maintenance port 32 is provided on the outer casing of the filter 30, which is sealed by a threaded cap 33 for easy periodic cleaning of the filter screen 31. A waterproof connector 34 is installed at the outlet end of the electrical lead trough 20. A sealing ring 35 is provided on the inner wall of the waterproof connector 34 to prevent external moisture from entering the electrical lead trough 20. The waterproof connector 34 is threaded to the outlet end of the electrical lead trough 20, and an anti-loosening nut 36 is provided on its exterior to enhance the reliability of the connection. The above design further improves the practicality and reliability of the integrated functional module 5.

[0031] The bottom of the support frame 1 is provided with support feet 27, which are fixedly connected to the bottom surface of the support frame 1 by bolts 28. A shock-absorbing pad 29, made of rubber, is installed at the bottom of the support feet 27 to absorb vibrations generated during motor operation. The design of the support feet 27 and the shock-absorbing pad 29 effectively reduces the impact of motor vibration on the support frame 1, thereby improving the overall structural stability.

[0032] In practical applications, the stator assembly module of this invention is suitable for stator support design of high-power motors. During assembly, multiple arc-shaped segment pieces 2 are first spliced ​​circumferentially into a ring structure. The bolt group 10, positioning pins 11, and sealing washers 12 in the modular connection assembly 3 are used to fix adjacent arc-shaped segment pieces 2. Subsequently, positioning and locking units 4 are installed at both axial ends of the arc-shaped segment pieces 2. The clamping force of the elastic pressure block 17 is adjusted by adjusting the screw 16 to ensure the support frame 1 remains stable in both the axial and circumferential directions. Next, the integrated functional module 5 is embedded in the internal cavity of the support frame 1, and the coolant flow and electrical lead wire arrangement are achieved through the cooling pipe 19 and electrical lead wire groove 20, respectively. Finally, support feet 27 and shock-absorbing pads 29 are installed at the bottom of the support frame 1, completing the assembly process of the entire stator assembly module.

[0033] This invention utilizes a modular design to decompose the support frame 1 into multiple arc-shaped segmented parts 2, and achieves rapid assembly through modular connecting components 3, significantly reducing transportation difficulty and assembly complexity. The positioning and locking unit 4, through the synergistic action of the locking ring 15, adjusting screw 16, and elastic pressure block 17, provides reliable positioning and locking in the axial and circumferential directions. The integrated functional module 5 organically combines the cooling pipe 19 with the electrical lead-in slot 20, meeting the heat dissipation and wiring requirements of high-performance motors and improving overall functionality. These technical means address the shortcomings of existing technologies in terms of structural stability, ease of assembly, and functional integration, providing an innovative solution for the design of stator supports for high-power motors.

[0034] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.

[0035] In practical applications, the stator assembly module of this invention is suitable for stator support design of high-power motors. The following, in conjunction with the accompanying drawings and specific component numbers, details its operating principle and implementation steps.

[0036] First, during transportation, multiple arc-shaped segment components 2 are decomposed into independent units through modular design. Each arc-shaped segment component 2 has a lifting lug 24 on its outer wall, with threaded holes 25 inside for installing eye bolts 26. By fixing the eye bolts 26 to the lifting lug 24 using lifting equipment, the lifting operation of the arc-shaped segment component 2 can be easily completed. This design significantly reduces volume constraints during transportation and improves transportation efficiency. Furthermore, reinforcing ribs 6 are radially distributed along the inner wall of the arc-shaped segment component 2 and welded to the outer wall, enhancing the overall rigidity of the arc-shaped segment component 2 and ensuring that it is not easily deformed during transportation.

[0037] Subsequently, during the assembly process, the stepped mating surfaces 7 of adjacent arc-shaped segment pieces 2 are first aligned. The stepped mating surfaces 7 include radial mating surfaces 8 and axial mating surfaces 9, which are perpendicular to each other, effectively ensuring coaxiality after assembly. Positioning pins 11 are embedded in pin holes 14 on the radial mating surfaces 8 for precise positioning, ensuring accurate positioning between adjacent arc-shaped segment pieces 2. Next, bolt sets 10 are used to penetrate the mating end faces of adjacent arc-shaped segment pieces 2 and are locked in place with nuts 13. Sealing washers 12 are sandwiched between the axial mating surfaces 9 to prevent external contaminants from entering the internal cavity of the support frame 1. This step not only achieves a secure connection between adjacent arc-shaped segment pieces 2 but also provides excellent sealing performance, preventing the intrusion of external impurities.

[0038] After the circumferential splicing of the arc-shaped segment 2 is completed, it needs to be positioned both axially and circumferentially. At this time, positioning and locking units 4 are installed at both axial ends of the arc-shaped segment 2. The locking ring 15 is sleeved on the outer wall of both axial ends of the support frame 1, and an annular groove 18 is opened on its inner side. An elastic pressure block 17 is embedded in the annular groove 18. One side of the elastic pressure block 17 contacts the inner wall of the locking ring 15, and the other side fits against the outer wall of the support frame 1. The adjusting screw 16 passes through the locking ring 15 and presses against the elastic pressure block 17. The clamping force of the elastic pressure block 17 on the support frame 1 is changed by rotating the adjusting screw 16. This design achieves dual locking in both axial and circumferential directions through the synergistic action of the locking ring 15, the adjusting screw 16, and the elastic pressure block 17, effectively preventing relative displacement of the spliced ​​arc-shaped segment 2, thereby further improving the overall stability of the support frame 1.

[0039] Next, the integrated functional module 5 is embedded in the internal cavity of the support frame 1. The cooling pipe 19 is arranged radially along the support frame 1, with one end connected to the external cooling system and the other end connected to the distribution plate 21. The distribution plate 21 evenly distributes the coolant into the internal cavities of each arc-shaped segment 2, thereby achieving efficient heat dissipation. The electrical lead trough 20 is arranged axially along the support frame 1, and its interior is equipped with an insulating partition 22 to isolate electrical leads of different voltage levels. The cooling pipe 19 and the electrical lead trough 20 are separated by a thermal insulation layer 23, which is made of a low thermal conductivity material to reduce heat transfer between the coolant and the electrical leads. This design organically combines the cooling pipe 19 and the electrical lead trough 20, meeting the heat dissipation and wiring requirements of high-performance motors.

[0040] A filter 30 is installed at the inlet end of the cooling pipe 19. The filter 30 contains a filter screen 31 to intercept impurities in the coolant. A maintenance port 32 is provided on the outer casing of the filter 30, which is sealed by a threaded cap 33 for easy periodic cleaning of the filter screen 31. A waterproof connector 34 is installed at the outlet end of the electrical lead trough 20. A sealing ring 35 is provided on the inner wall of the waterproof connector 34 to prevent external moisture from entering the electrical lead trough 20. The waterproof connector 34 is threaded to the outlet end of the electrical lead trough 20, and an anti-loosening nut 36 is provided on its exterior to enhance the reliability of the connection. These detailed design features further enhance the practicality and reliability of the integrated functional module 5.

[0041] Finally, support feet 27 and shock-absorbing pads 29 are installed at the bottom of the support frame 1. Support feet 27 are fixedly connected to the bottom surface of the support frame 1 by bolts 28, and shock-absorbing pads 29 are installed at their bottom. The shock-absorbing pads 29 are made of rubber and are used to absorb vibrations generated during motor operation. This design effectively reduces the impact of motor vibrations on the support frame 1, thereby improving the overall structural stability.

[0042] In summary, this invention achieves rapid assembly of the arc-shaped segment 2 through modular design, significantly reducing transportation difficulty and assembly complexity; the synergistic effect of the positioning and locking unit 4 provides reliable positioning and locking in the axial and circumferential directions; and the integrated functional module 5 meets the heat dissipation and wiring requirements of high-performance motors. These technical means address the shortcomings of existing technologies in terms of structural stability, ease of assembly, and functional integration, providing an innovative solution for the design of stator supports for high-power motors.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
