Description

Technical Field

[0001] This invention relates to the field of rotor processing, and in particular to a rotor oiling and drying equipment. Background Technology

[0002] The rotor is the core rotating component of an electric motor, converting energy through its interaction with the stationary stator. In an electric motor, the rotor cuts magnetic field lines via electromagnetic induction, converting electrical energy into mechanical energy. Rotors have extremely wide applications, encompassing industrial motors, wind turbine generators, automotive engines, compressors, and even motors for micro-drones; they are a key component in modern mechanical power transmission and energy conversion.

[0003] To ensure the service life and insulation effect of the rotor during the production process, it is usually necessary to coat the rotor surface with insulating oil. Currently, the main method for coating the rotor with insulating oil is to immerse the rotor in insulating oil and then remove the rotor.

[0004] The above-mentioned method of coating the insulating oil results in a large amount of insulating oil adhering to the rotor surface when the rotor is removed. This causes the rotor to need to stand for a long time after the insulating oil is coated before the insulating oil can drip off completely before the rotor can be processed. This affects the processing efficiency of coating the rotor with insulating oil. Summary of the Invention

[0005] In order to facilitate the rapid removal of insulating oil from the rotor surface and ensure the processing efficiency of rotor coating with insulating oil, this application provides a rotor oiling and drying device.

[0006] This application provides a rotor oiling and drying device, which adopts the following technical solution: A rotor oiling and drying device includes a device body and a spraying unit, a drying unit, and a conveying unit disposed on the device body. The conveying unit includes a placement fixture and a conveying mechanism. The placement fixture is used to place the rotor, and the conveying mechanism is used to convey the placement fixture between the spraying unit and the drying unit. The spraying unit includes an oiling mechanism, a rotating mechanism, and a scraping mechanism. The oiling mechanism includes an oiling nozzle for spraying oil onto the rotor. The rotating mechanism is used to drive the rotor to rotate. The scraping mechanism includes a scraper and a swinging assembly. The scraper is used to scrape oil from the rotor surface, and the swinging assembly is used to drive the scraper to swing. The drying unit is used to dry the rotor coated with insulating oil.

[0007] By adopting the above technical solution, when coating the rotor with insulating oil, the rotor is first placed in a placement fixture, and then the placement fixture is sent to the spraying unit by a conveying mechanism. The insulating oil is then sprayed onto the rotor surface through an oil spraying nozzle. During the spraying process, the rotor is driven to rotate by a rotating mechanism, which helps to ensure the uniformity of the insulating oil spraying on the rotor surface. After the insulating oil is sprayed, the oscillating component drives the scraper to swing, which facilitates the quick removal of excess insulating oil from the rotor surface. This makes it easier to send the rotor to the drying unit for stable drying treatment and to achieve the curing of the insulating oil. By using the insulating oil spraying method in conjunction with the scraper to scrape the rotor surface, the rotor does not need to stand for a long time after the insulating oil is coated. When the rotor is sent from the spraying unit to the drying unit, it no longer drips oil, which helps to ensure the processing efficiency of coating the rotor with insulating oil.

[0008] Optionally, the placement fixture includes a placement base plate and a placement base. Two placement bases are arranged opposite each other. Both placement bases are fixedly installed on the top of the placement base plate. The top of each placement base is provided with a placement groove for placing the rotor shaft. A placement bearing is rotatably arranged in the placement groove.

[0009] By adopting the above technical solution, when the rotor is placed in the placement fixture, the rotor shaft is placed in two placement grooves respectively, which helps to ensure the stability of the rotor's position, that is, the stability of the rotor when placed in the placement fixture. At the same time, the placement bearing makes it less likely for the rotor to experience wear due to friction with the placement base when rotating.

[0010] Optionally, both placement bases are rotatably mounted with placement top seats, which are fixed to the placement bases by a locking buckle. The placement bases are provided with placement clearance grooves for making way for the rotor shaft, and clearance bearings are rotatably disposed in the placement clearance grooves.

[0011] By adopting the above technical solution, the placement of the top seat, through the cooperation of the placement clearance groove and the placement recess, plays a further limiting role in the placement of the rotor, which helps to further ensure the stability of the rotor's position when placed on the placement frame.

[0012] Optionally, the rotating mechanism includes a rotating motor, a driving sprocket, a driven sprocket, a rotating chain, and a rotating sprocket. The driving sprocket and the driven sprocket are distributed horizontally and are rotatably mounted on the equipment body. The rotating chain is wound around the driving sprocket and the driven sprocket. The rotating motor is used to drive the driving sprocket to rotate. The rotating sprocket meshes with the rotating chain and is used to rotate on the rotor shaft.

[0013] By adopting the above technical solution, the rotating sprocket is installed on the rotor shaft, and the rotation of the driving sprocket is driven by the rotating motor, so that the driven sprocket drives the rotating chain to perform synchronous transmission, thereby making the rotating sprocket drive the rotor to rotate together, which is convenient and stable.

[0014] Optionally, the placement base is provided with two limiting components, which are respectively located on opposite sides of the two placement bases. Each limiting component includes a limiting fixing ring and a limiting rotating ring. The limiting fixing ring has a limiting fixing hole for the rotor shaft to pass through. The limiting fixing ring has multiple elastic limiting parts distributed circumferentially around its own axis. The limiting rotating ring is sleeved and threaded onto the limiting fixing ring. When the limiting rotating ring moves toward the limiting fixing ring, each of the elastic limiting parts moves toward the axis of the limiting fixing ring. The rotating sprocket is coaxially fixedly installed on one of the limiting fixing rings.

[0015] By adopting the above technical solution, after the rotor shaft is inserted into the limiting and fixing hole, the rotation of the limiting rotating ring is caused by applying force, so that each elastic limiting part can abut against the rotor shaft, thereby fixing the limiting and fixing ring to the rotor shaft. When the two limiting and fixing rings abut against the two sides of the two placement bases that are far apart, they play a further limiting role in the position of the rotor, which helps to ensure the stability of the rotor's position when the insulating oil is sprayed, and further ensures the spraying effect of the insulating oil on the rotor.

[0016] Optionally, each of the two placement bases is provided with a placement limiting rod on the side away from each other, and a limiting roller is rotatably installed on the end of each of the two placement limiting rods that is away from each other. Each of the two limiting fixing rings is provided with a limiting movable groove that extends around its own axis and is arranged in a ring. When the limiting fixing ring is fixed to the rotor shaft, the limiting roller rolls in cooperation with the limiting movable groove.

[0017] By adopting the above technical solution, the cooperation between the limiting roller and the limiting movable groove reduces the friction between the limiting fixed ring and the placement base when the limiting fixed ring rotates, which helps to ensure the stable limiting of the rotor while further ensuring the smooth and stable rotation of the rotor.

[0018] Optionally, the swing assembly includes a swing motor, a swing drive rod, a swing connecting rod, a swing driven rod, and a swing rotating rod. The swing drive rod is fixedly installed at the output end of the swing motor. One end of the swing connecting rod is rotatably installed on the swing drive rod, and the other end is rotatably installed on the swing driven rod. The swing driven rod is fixedly installed on the swing rotating rod. The swing rotating rod is rotatably installed on the main body of the placement rack equipment, and the scraper is fixedly installed on the swing rotating rod.

[0019] By adopting the above technical solution, when the swing motor drives its own output end to rotate, the swing active rod drives the swing driven rod to swing back and forth through the swing connecting rod, thereby causing the swing rotating rod to drive the scraper to swing back and forth together with the swing driven rod. The scraper can be swung back and forth without the swing motor driving its own output end to rotate in both directions, which is convenient and stable.

[0020] Optionally, the scraper includes a scraping fixing part and a scraping part. The scraping fixing part is installed on the swing rotating rod, and the scraping part is installed on the side of the scraping fixing part away from the swing rotating rod. The scraping part has multiple adjusting strip holes distributed along its own length direction. Each adjusting strip hole is provided with a scraping bolt. The scraping bolts are sequentially inserted into the scraping fixing part and the adjusting strip holes and are threaded with scraping nuts. The material of the scraping part is selected as rubber.

[0021] By adopting the above technical solution, firstly, the rubber scraper part makes it less likely for the rotor to experience wear due to rigid contact with the scraper during the oiling process. Secondly, by turning the scraper nut and moving the scraper part, the scraper bolt can move within the adjustment slot, which facilitates the fine adjustment of the position of the scraper part. This makes it easy to adapt to rotors of different sizes or to adjust the position of the same rotor according to the actual coating needs, thus making it highly applicable.

[0022] Optionally, the scraper fixing part is fixedly connected with two scraper fixing rods. Each scraper fixing rod has two opposite fixing rod bodies, one of which is elastic. Each of the opposite sides of the two fixing rod bodies has a fixing half-groove for the swinging rod to pass through. The scraper fixing rod is provided with a fixing bolt, which passes through one of the fixing rod bodies and is threadedly engaged with the other fixing rod body.

[0023] By adopting the above technical solution, the swinging rod is inserted into the fixed half-groove of the two fixed rods, and then the two scraper fixing rods are tightened to abut the swinging rod by screwing the fixing bolts, thus fixing the swinging rod and the scraper fixing rod. This is convenient and quick, and the scraper fixing rod can be fixed at different angle positions of the swinging rod, which makes it easier for the scraper to scrape the rotor with insulating oil in different angle ranges according to actual needs, making it more versatile.

[0024] Optionally, it also includes a preheating unit, which is used to heat the rotor entering the spraying unit, and the conveying unit is also used to convey the placement fixture between the preheating unit and the spraying unit; the preheating unit is provided with a preheating channel, and the equipment body is provided with an opening and closing component for closing or opening the openings on both sides of the preheating channel.

[0025] By adopting the above technical solution, the setting of the preheating unit facilitates the removal of surface moisture and the evaporation or softening of impurities by heat before the rotor is coated with insulating oil. This helps to ensure the cleanliness and dryness of the rotor coating surface and provides a better adhesion environment for the insulating oil. At the same time, the setting of the opening and closing components makes it difficult for heat to evaporate outside the preheating unit during the rotor heating process, which helps to ensure the preheating effect of the rotor.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By using insulating oil spraying in conjunction with scraping the rotor surface, the rotor does not need to stand for a long time after the insulating oil is applied. When the rotor is sent from the spraying unit to the drying unit, it no longer drips oil, which helps to ensure the processing efficiency of the rotor insulating oil coating.

[0027] 2. When the rotor is placed in the placement fixture, the rotor shaft is placed in two placement grooves, which helps to ensure the stability of the rotor's position. At the same time, the placement bearings make it less likely for the rotor to wear due to friction with the placement base when it rotates.

[0028] 3. The preheating unit facilitates the removal of surface moisture from the rotor before the insulating oil is applied, and allows impurities to evaporate or soften due to heat. This helps ensure the cleanliness and dryness of the rotor coating surface, providing a better adhesion environment for the insulating oil. Attached Figure Description

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses a rotor oiling and drying device. Example 1

[0039] Reference Figure 1 The rotor oiling and drying equipment includes a main body 1 and a preheating unit 2, a spraying unit 3, a drying unit 4 and a conveying unit disposed on the main body 1. In this embodiment, the length direction of the main body 1 is the x-axis direction and the width direction is the y-axis direction. The preheating unit 2, the spraying unit 3 and the drying unit 4 are distributed sequentially along the length direction of the main body 1.

[0040] Reference Figure 1 and Figure 2The conveying unit includes a placement fixture 5 and a conveying mechanism. The conveying mechanism includes a conveying drive roller 6, a conveying driven roller 7, a conveyor belt 8, and a conveying motor 9. The conveying drive roller 6 and the conveying driven roller 7 are respectively located near both ends of the equipment body 1 along the length direction and are arranged along the y-axis. The conveying motor 9 is installed on the equipment body 1 and is used to drive the conveying drive roller 6 to rotate. In this embodiment, two conveyor belts 8 are provided and are respectively located near both sides of the equipment body 1 along the y-axis. Both conveyor belts 8 are wound around the conveying drive roller 6 and the driven roller. The placement fixture 5 is installed on the top of the two conveyor belts 8 so that when the driven roller rotates, the placement fixture 5 moves along the length direction of the equipment body 1, i.e., the x-axis, driven by the conveyor belts 8, thereby realizing the movement of the placement fixture 5 between the preheating unit 2, the spraying unit 3, and the drying unit 4.

[0041] Reference Figure 1 The preheating unit 2 heats the rotor 26 entering the spraying unit 3. A preheating channel 10 extends through the preheating unit 2 along the x-axis, allowing the placement fixture 5 to pass through and preheating the rotor 26 placed on the fixture 5 within the preheating channel 10. The drying unit 4 dries the rotor 26 after it has been coated with insulating oil. A drying channel 11 extends through the drying unit 4 along the x-axis, allowing the placement fixture 5 to pass through and drying the rotor 26 placed on the fixture 5 within the drying channel 11. The preheating unit 2 facilitates the removal of surface moisture from the rotor 26 before coating with insulating oil and allows impurities to evaporate or soften due to heat, ensuring a clean and dry coating surface and providing a better adhesion environment for the insulating oil. The drying unit 4 facilitates the curing of the insulating oil, thus transforming the penetration effect of the insulating oil into durable insulation performance.

[0042] Continue to refer to Figure 1The main body of the equipment 1 is provided with an opening and closing component for closing or opening the openings on both sides of the preheating channel 10 and the drying channel 11. The structures of each closing component are the same. In this embodiment, the opening and closing component on one side of the preheating channel 10 is described in detail. The enclosure assembly includes an enclosure plate 12, a lifting motor 13, a lifting drive shaft 14, and lifting ropes 15. The enclosure plate 12 slides vertically onto the equipment body 1. The lifting drive shaft 14 is mounted on the equipment body 1 along the y-axis and rotates. The lifting motor 13 is mounted on the top of the equipment body 1 and drives the lifting drive shaft 14 to rotate via a reducer. In this embodiment, two lifting ropes 15 are provided. One end of each rope is fixedly wound around the lifting drive shaft 14, and the other end is fixedly mounted on the enclosure plate 12. The two lifting ropes 15 are respectively positioned close to both sides of the enclosure plate 12 along the y-axis. When the lifting motor 13 drives the lifting drive shaft 14 to rotate, the lifting ropes 15 drive the enclosure plate 12 to move vertically, thereby opening and closing one side of the preheating channel 10, which is convenient and stable. The enclosure of the preheating channel 10 and the drying channel 11 by the opening and closing assembly helps to fully ensure the preheating and drying effects of the rotor 26.

[0043] Reference Figure 2 and Figure 3 The placement fixture 5 includes a placement base plate 501 and two placement bases 502. Both placement bases 502 are fixedly installed on the top of the placement base plate 501 and distributed along the y-axis. Each placement base 502 has a placement groove 16 on its top for placing the rotor 26's shaft. Each placement base 502 is rotatably mounted with two placement bearings 17. Both placement bearings 17 are located within the placement groove 16, and their outer circumferential surfaces are within the area of ​​the placement groove 16. When the rotor 26's shaft is placed in the placement groove 16, the two placement bearings 17 are located on both sides of the rotor 26's axis and abut against the rotor 26's shaft, allowing for smooth rotation of the rotor 26's shaft after placement in the placement groove 16.

[0044] Continue referring to Figure 2 and Figure 3To further ensure the stability of the rotor 26's shaft position when placed within the placement groove 16, both placement bases 502 are rotatably equipped with placement top seats 18. The placement top seats 18 are arc-shaped and fixed to the placement bases 502 by latches 19. The latches 19 are existing quick-lock latches and will not be described further here. A placement clearance groove 20 is provided on one side of the placement top seat 18 to allow clearance for the rotor 26's shaft. When the rotor 26's shaft is placed in the placement groove 16 and the placement top seat 18 is fixed to the placement base 502, the rotor 26's shaft is located within the area enclosed by the placement groove 16 and the placement clearance groove 20. A clearance bearing 21 is rotatably mounted on the placement top seat 18. The clearance bearing 21 is located within the placement clearance groove 20, and its outer circumferential surface is within the placement clearance groove 20 area, further ensuring the smooth and stable rotation of the rotor 26's shaft.

[0045] Reference Figure 2 The base plate 501 has a rectangular spray hole 22 that runs vertically through the center. The spraying unit 3 has a spraying area 23 corresponding to the spray hole 22. The spraying area 23 has a collection box 24 with an open top. When the placement fixture 5 moves to the spraying unit 3, the collection box 24 is located at the bottom of the placement fixture 5 and the spray hole 22 corresponds to the top opening of the collection box 24, so that the collection box 24 can collect and process the insulating oil dripping from the spray.

[0046] Reference Figure 3 The spraying unit 3 includes an oiling mechanism, a rotating mechanism, and a scraping mechanism. The oiling mechanism includes an oiling nozzle 25. In this embodiment, multiple oiling nozzles 25 are located inside the collection box 24 and are evenly distributed along the y-axis. Each oiling nozzle 25 is connected to an external oil storage tank (not shown in the figure) containing insulating oil through a pipe. When the rotor 26 is placed on the placement fixture 5 and the placement fixture 5 moves to the spraying unit 3, each oiling nozzle 25 is located at the bottom of the rotor 26 and faces the rotor 26 so as to spray the insulating oil onto the surface of the rotor 26.

[0047] Reference Figure 2 and Figure 3 The equipment body 1 is fixedly mounted with a vertically arranged rotating mounting plate 27, which is located on the side of one of the placement bases 502 away from the other placement base 502. The rotating mechanism includes a rotating motor 28, a driving sprocket 29, a driven sprocket 30, a rotating chain 31, and a rotating sprocket 32. The driving sprocket 29 and the driven sprocket 30 are both rotatably mounted on the side of the rotating mounting plate 27 facing the placement base 502 and are horizontally distributed along the x-axis.

[0048] Reference Figure 3A rotary motor 28 is mounted on the side of a rotary mounting plate 27 away from the drive sprocket 29. The output end of the rotary motor 28 passes through and is rotatably mounted on the rotary mounting plate 27. The drive sprocket 29 is coaxially fixedly mounted on the output end of the rotary motor 28, so that the rotary motor 28 drives the drive sprocket 29 to rotate. A rotary chain 31 is wound around the drive sprocket 29 and the driven sprocket 30, so that when the drive sprocket 29 rotates, the driven sprocket 30 drives the rotary chain 31 to move together.

[0049] Reference Figure 2 The rotating sprocket 32 ​​is coaxially fixed to the rotating shaft of the rotor 26. After the rotating shaft of the rotor 26 is placed on the placement base 502 and the placement fixture 5 is moved to the spraying unit 3, the rotating sprocket 32 ​​meshes with the rotating chain 31 so that when the rotating chain 31 rotates, the rotating sprocket 32 ​​drives the rotor 26 to rotate synchronously, which helps to ensure the uniformity and stability of the insulating oil spraying.

[0050] Reference Figure 2 and Figure 3 The scraping mechanism includes a scraper 33 and a swing assembly. The shaft of the rotor 26 is placed on the placement base 502 and the placement fixture 5 is moved to the spraying unit 3. The scraper 33 is located at the bottom of the rotor 26. The scraper 33 and the oil spray nozzle 25 are respectively arranged on both sides close to the x-axis direction of the rotor 26. The swing assembly drives the scraper 33 to swing so that the scraper 33 can quickly scrape off the excess insulating oil on the surface of the rotor 26.

[0051] Reference Figure 3 and Figure 4 Specifically, the swing assembly includes a swing motor 34, a swing rod 35, a swing drive rod 36, a swing connecting rod 37, and a swing driven rod 38. The swing motor 34 is installed on the equipment body 1. The swing drive rod 36 is fixedly installed on the output end of the swing motor 34. One end of the swing connecting rod 37 is rotatably installed on the swing drive rod 36, and the other end is rotatably installed on the swing driven rod 38. The swing driven rod 38 is fixedly installed on the swing rod 35. The swing rod 35 is set along the y-axis and rotatably installed on the collection box 24. The scraper 33 is fixedly installed on the swing rod 35, so that when the swing motor 34 drives the swing drive rod 36 to rotate, the swing connecting rod 37 drives the swing rod 35 to reciprocate through the swing driven rod 38, thereby realizing the reciprocating swing of the scraper 33.

[0052] Reference Figure 4The scraper 33 includes a scraping fixing part 331 and a scraping part 332. The scraping fixing part 331 is fixedly connected to two scraping fixing rods 39. Each scraping fixing rod 39 has two opposing fixing rod bodies 391, one of which is elastic. Each of the opposing sides of the two fixing rod bodies 391 has a fixing half-groove 40 for the swinging rotating rod 35 to pass through. The scraping fixing rod 39 is provided with a fixing bolt 41, which passes through one fixing rod body 391 and is connected to the other fixing rod body 392. The 91 threaded connection allows the swing rod 35 to pass through the two fixed half-grooves 40 opposite the two fixed rods 391. By tightening the fixing bolts 41, the groove walls of the two fixed half-grooves 40 can clamp the swing rod 35, thus fixing the scraper 33 and the swing rod 35. This is convenient and quick. Furthermore, the two fixed rods 391 can be fixed at different angle positions of the swing rod 35, which makes it easier for the scraper 33 to scrape the insulating oil coating onto the rotor 26 within different angle ranges according to actual needs, thus making it more versatile.

[0053] Continue to refer to Figure 4 The material of the scraper part 332 is selected as rubber. The scraper part 332 is installed on the side of the scraper fixing part 331 away from the fixing rod, i.e. the swing rotating rod 35, so that the scraper part 332 scrapes the rotor 26 during the oiling process, thereby making the rotor 26 less prone to wear caused by rigid contact with the scraper 33.

[0054] Continue to refer to Figure 4 Furthermore, the scraper section 332 has multiple adjusting slots 42 distributed along its own length direction, i.e., the y-axis direction. The adjusting slots 42 extend along the x-axis direction, and each adjusting slot 42 has a scraper bolt 43 inserted into it. In this embodiment, the scraper bolts 43 are sequentially inserted from top to bottom into the scraper fixing section 331 and the adjusting slots 42, and one end of the scraper bolt 43 inserted into the adjusting slot 42 is threaded with a scraper nut 44 to achieve a stable fixation between the scraper section 332 and the scraper fixing section 331. The setting of the adjusting slots 42 facilitates the fine adjustment of the position of the scraper section 332, thereby facilitating the scraper 33 to adapt to rotors 26 of different sizes or to adjust the scraping position of the same rotor 26 according to the actual coating needs, thus having strong applicability.

[0055] The implementation principle of Example 1 is as follows: When it is necessary to coat the rotor 26 with insulating oil, the rotor 26 is first placed in the placement fixture 5, and then the placement fixture 5 is transported by the conveyor belt 8. The placement fixture 5 is first sent to the preheating unit 2 to heat the rotor 26, and then the placement fixture 5 drives the rotor 26 to the spraying unit 3. The insulating oil is sprayed onto the surface of the rotor 26 through the oil spray nozzle 25. During the spraying process, the rotor 26 is driven to rotate by the cooperation of the rotating chain 31 and the rotating sprocket 32, which helps to ensure that the insulating oil is coated on the rotor 26. The uniformity of surface coating is ensured by the oscillating motion of the drive scraper 33 after the insulating oil is sprayed, which facilitates the rapid removal of excess insulating oil from the surface of the rotor 26. This allows the rotor 26 to be easily fed into the drying unit 4 for stable drying, thus achieving the curing of the insulating oil. The combination of insulating oil spraying and scraping treatment of the rotor 26 surface by the scraper 33 ensures that the rotor 26 does not need to stand for a long time after the insulating oil is applied, and the rotor 26 can be fed from the spraying unit 3 to the drying unit 4 without dripping oil. This helps to ensure the processing efficiency of coating the rotor 26 with insulating oil. Example 2

[0056] Reference Figure 5 The difference between this embodiment and embodiment 1 is that the installation method between the rotating sprocket 32 ​​and the rotor 26 shaft is different. In this embodiment, a limiting component is provided on the side of the two placement bases 502 that are far apart. Specifically, the limiting component includes a limiting fixing ring 45 and a limiting rotating ring 46. The limiting fixing ring 45 has a limiting fixing hole 47 that is provided through it along its own axis for the rotor 26 shaft to pass through.

[0057] Reference Figure 6 and Figure 7 The limiting and fixing ring 45 is uniformly provided with multiple elastic limiting parts 48 around its own axis. The limiting rotating ring 46 is sleeved and threadedly fitted to the limiting and fixing ring 45. The limiting rotating ring 46 is provided with a pressing guide surface 49. When the limiting rotating ring 46 is rotated so that the rotating limiting ring moves closer to the limiting and fixing ring 45, each elastic limiting part 48 moves closer to the axis of the limiting and fixing ring 45 under the pressing action of the pressing guide surface 49, thereby achieving tight fixing of the rotor 26 shaft. When the limiting rotating ring 46 is rotated so that the rotating limiting ring moves away from the limiting and fixing ring 45, each elastic limiting part 48 moves away from the axis of the limiting and fixing ring 45 under its own elastic force, thereby releasing the tight fixing of the rotor 26 shaft. When the two limiting and fixing rings 45 are fixed in position, they play a further limiting role in the position of the rotor 26, which helps to ensure the stability of the rotor 26 when it is sprayed with insulating oil.

[0058] Continue to refer to Figure 6 and Figure 7The rotating sprocket 32 ​​is coaxially fixedly mounted on the limiting fixing ring 45 near the rotating mounting plate 27, so that the rotating sprocket 32 ​​can be disassembled and assembled together with the limiting fixing ring 45, making the disassembly and assembly of the rotating sprocket 32 ​​more convenient. In order to facilitate the quick installation of the limiting fixing ring 45 to the required position and reduce the friction between the limiting fixing ring 45 and the placement base 502 when the limiting fixing ring 45 rotates together with the rotor 26 shaft, a placement limiting rod 50 is fixedly provided on the side of the two placement bases 502 that are far apart, and a limiting roller 51 is rotatably mounted on the end of the two placement limiting rods 50 that are far apart. A limiting movable groove 52 extending around its own axis and arranged in a ring is opened on the side of the two limiting fixing rings 45 that are close together. The limiting roller 51 corresponds to the limiting movable groove 52 and rolls with the limiting movable groove 52 to provide a positioning indication when the limiting fixing ring 45 is installed.

[0059] The implementation principle of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
