Description

Technical Field

[0001] This utility model relates to the field of low-noise motor technology, and in particular to a low-noise motor that is easy to maintain. Background Technology

[0002] Low-noise motors are power devices that reduce operating noise and vibration through optimized electromagnetic design and mechanical structure. They are mainly used in applications requiring high levels of quietness and stability. These motors are used in industries such as manufacturing, home appliances, and medical equipment. Their classification system covers dimensions such as power supply type, working principle, and starting method. Based on power supply, they can be divided into DC and AC motors, with AC motors further divided into single-phase and three-phase types. Based on working principle, they can be divided into synchronous, asynchronous, and DC motors. Synchronous motors include permanent magnet and reluctance types, while asynchronous motors encompass induction motors and commutator motors.

[0003] Low-noise motors require maintenance during use. This involves removing the motor's cover to inspect the internal components. However, the cover is secured with multiple bolts, requiring the removal of these bolts before maintenance can proceed. After maintenance, the cover is then secured back with bolts, which are then tightened sequentially. This process is time-consuming. To address these issues, this application proposes a low-noise motor that facilitates maintenance. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A low-noise motor that is easy to maintain includes a low-noise motor body. A cover plate is overlapped on the right side of the low-noise motor body. A first limiting plate is fixedly installed on the surface of the low-noise motor body, and a second limiting plate is fixedly installed on the surface of the cover plate.

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Refer to Figure 1-6A low-noise motor that is easy to maintain includes a low-noise motor body 1. A cover plate 2 is overlapped on the right side of the low-noise motor body 1. A first limiting plate 3 is fixedly installed on the surface of the low-noise motor body 1, and a second limiting plate 4 is fixedly installed on the surface of the cover plate 2. The first limiting plate 3 and the second limiting plate 4 overlap. An upper fixing plate 5 and a lower fixing plate 6 are overlapped on the surface of the second limiting plate 4. Both the upper fixing plate 5 and the lower fixing plate 6 are semi-circular structures. Both the upper fixing plate 5 and the lower fixing plate 6 are made of metal and have the same specifications. Both the upper fixing plate 5 and the lower fixing plate 6 overlap with the first limiting plate 3. A connecting component is provided on the front side of the upper fixing plate 5, and a fixing component is provided on the right side of the upper fixing plate 5. The cover plate 2 has a sealing assembly inside. The connecting assembly includes two connecting plates 7, which are respectively fixedly installed on the front side of the upper fixing plate 5 and the front side of the lower fixing plate 6. A mounting shaft 8 is rotatably mounted inside each connecting plate 7. The mounting shaft 8 has a circular structure and is made of metal. A U-shaped plate 9 is fixedly mounted at the end of the mounting shaft 8. The fixing assembly includes a mounting plate 10 fixedly installed on the rear side of the upper fixing plate 5. A connecting post 11 is rotatably mounted inside the mounting plate 10. A mounting sleeve 12 is fixedly mounted at the end of the connecting post 11. An upper circular plate 13 is fixedly mounted at the top of the mounting sleeve 12, and a lower circular plate 14 is fixedly mounted at the bottom of the mounting sleeve 12. A fixing screw 15 is internally connected to the lower circular plate 14. Four aligning posts 16 are fixedly mounted on the surface of the fixing screw 15, arranged symmetrically. The aligning posts 16 are made of metal and overlap with the lower circular plate 14. A limiting nut 17 is threaded onto the top of the fixing screw 15. A U-shaped limiting plate 20 is also attached to the surface of the fixing screw 15 and fixedly installed on the rear side of the lower fixing plate 6. A fixing nut 18 is threaded onto the surface of the fixing screw 15, and a fixing circular plate 19 is attached to the top of the fixing nut 18. The fixing circular plate 19, the U-shaped limiting plate 20, and the fixing screw 15 are all connected in an overlapping manner. This allows for adjustments to the low-noise electrical circuit. When the main body 1 is under maintenance, rotating the fixing nut 18 separates the fixing circular plate 19 from the U-shaped limiting plate 20. The fixing screw 15 drives the connecting column 11 to rotate inside the mounting plate 10 through the mounting sleeve 12, causing the fixing screw 15 to move out of the U-shaped limiting plate 20. This pulls the upper fixing plate 5 and the lower fixing plate 6, causing the connecting plate 7 to rotate on the surface of the mounting shaft 8, thus separating the upper fixing plate 5 and the lower fixing plate 6 from the low-noise motor main body 1 and the cover plate 2. The cover plate 2 is then removed from the low-noise motor main body 1, separating the limiting plate 3 and the limiting plate 4, allowing maintenance of the low-noise motor main body 1. When the fixing screw 15 is damaged, removing the limiting nut 17 from the fixing screw 15 allows the fixing screw 15 to be moved out of the mounting sleeve 12.This process involves moving the fixing screw 15, which in turn moves the alignment pin 16 out of the lower circular plate 14. The replacement fixing screw 15 is then inserted into the mounting sleeve 12, and the fixing screw 15 again drives the alignment pin 16 into the lower circular plate 14. Finally, the limiting nut 17 is tightened onto the surface of the fixing screw 15, completing the replacement of the fixing screw 15. This makes the inspection of the low-noise motor body 1 more convenient, avoiding the need to remove multiple bolts to remove the cover plate 2 for maintenance of the low-noise motor. It also avoids the need to fix the cover plate 2 with multiple bolts and tighten them sequentially after maintenance.

[0017] Specifically, the sealing assembly includes a mounting ring 21 fixedly installed inside the cover plate 2. A sealing ring 22 is fixedly installed inside the mounting ring 21. When the cover plate 2 is placed on the right side of the low-noise motor body 1, the cover plate 2 is inserted into the interior of the low-noise motor body 1 through the mounting ring 21. The mounting ring 21 drives the sealing ring 22 to be inserted into the interior of the low-noise motor body 1. When the inner wall of the low-noise motor body 1 compresses the sealing ring 22, the compression deformation of the sealing ring 22 seals the gap between the low-noise motor body 1 and the cover plate 2.

[0018] In use: When it is necessary to repair the low-noise motor body 1, rotate the fixing nut 18 to separate the fixing round plate 19 from the U-shaped limiting plate 20. Then pull the fixing screw 15 to rotate the mounting sleeve 12, causing the mounting sleeve 12 to rotate the connecting column 11 inside the mounting plate 10. This causes the fixing screw 15 to move out of the U-shaped limiting plate 20. Pull the upper fixing plate 5 and the lower fixing plate 6, causing the upper fixing plate 5 and the lower fixing plate 6 to rotate the connecting plate 7 on the surface of the mounting shaft 8. This separates the upper fixing plate 5 and the lower fixing plate 6 from the low-noise motor body 1 and the cover plate 2. Remove the cover plate 2 from the low-noise motor body 1, separating the limiting plate 1 3 and the limiting plate 2 4. The low-noise motor body 1 can then be repaired. After the repair is completed, place the cover plate 2 on... On the right side of the low-noise motor body 1, limit plate 3 and limit plate 4 are brought into contact. The upper fixing plate 5 and lower fixing plate 6 are placed on the surface of the low-noise motor body 1 and cover plate 2, so that limit plate 3 and limit plate 4 are inserted into the interior of upper fixing plate 5 and lower fixing plate 6. Pulling the fixing screw 15 causes the mounting sleeve 12 to rotate, so that the mounting sleeve 12 causes the connecting column 11 to rotate inside the mounting plate 10. This causes the fixing screw 15 to enter the interior of the U-shaped limit plate 20, and the fixing nut 18 is tightened, so that the fixing nut 18 makes tight contact between the fixing round plate 19 and the U-shaped limit plate 20, thereby fixing the position of the mounting plate 10, and thus fixing the positions of the upper fixing plate 5 and lower fixing plate 6, thus connecting the low-noise motor body 1 and cover plate 2.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
