Abstract
Description
Technical Field
[0001] The utility model relates to a wear repair device for a slip ring of a synchronous motor in a moving state, belonging to the technical field of mechanical repair. Background Art
[0002] Synchronous motors, as electrical equipment widely used in industrial applications, typically operate continuously. This prolonged, high-load operation can easily lead to wear and tear of the motor's internal components. Key components such as bearings, rotors, stators, and slip rings, in particular, can gradually wear out due to friction, heat, and vibration over time, impacting motor efficiency and potentially causing motor shutdown or failure.
[0003] Currently, traditional motor maintenance typically involves disassembly, inspection, repair, and component replacement after the equipment is shut down. For example, when repairing a slip ring, the machine must first be shut down and the power supply disconnected. After the motor is powered off, maintenance personnel must dismantle the slip ring for repair. This disassembly process is time-consuming and complex, especially for large motors, where precision and safety are essential. Next, the slip ring is inspected. The surface should be smooth. Significant wear, erosion, scratches, or dents indicate degraded contact performance and require post-disassembly repair by grinding or polishing. The repaired slip ring is then reassembled and debugged, and once verified to be functioning correctly, the motor is returned to production. This approach not only requires significant downtime but also significantly impacts production continuity and industrial efficiency. In critical applications, downtime can lead not only to production interruptions but also to significant financial losses.
[0004] Therefore, it is necessary to design a new wear repair device for synchronous motor slip rings in motion. This device can repair damaged parts in real time while the motor continues to operate, significantly reducing downtime and improving equipment efficiency. Furthermore, it features multi-axis movement and adjustment, allowing it to flexibly adapt to the repair needs of different parts of the synchronous motor slip ring, thus meeting the requirements for flexibility and efficiency during motor maintenance.

[0020] The present invention will be further described in detail below through the accompanying drawings and specific implementation methods.
[0021] like Figure 1-3As shown, the utility model is a wear repair device for a slip ring of a synchronous motor in a moving state, comprising a moving part 1 and a repairing part 4; the moving part 1 comprises a transverse moving part 21 and a longitudinal moving part 31, and the longitudinal moving part 31 connects the repairing part 4 and the transverse moving part 21; the transverse moving part 21 comprises a first screw 27, a first nut 25, a first wheel 26 and a first base 21; fixed plates are provided at both ends of the first base 21, one end of the first screw 27 is connected to the front fixed plate 22, and the other end is provided with a first limiting plate 24, which is connected to it; the first nut 25 is provided with a first threaded through hole 251, and the first screw 27 passes through the first threaded through hole 251; a cover with a first wheel 26 is provided between the rear fixed plate 23 and the first limiting plate 24 The plate 28, the first disc 26, and the first lead screw 27 form a first transmission structure 7. Rotation of the first disc 26 drives the first lead screw 27. The longitudinal movable portion 31 includes a second lead screw 37, a second nut 35, a second disc 36, and a second base 31. The second base 31 also has fixed plates at both ends. The second lead screw 37 is connected to an upper fixed plate 33 and a lower fixed plate 32 at both ends. The lower fixed plate 32 is mounted on the first nut 25. The second nut 35 is provided with a second threaded through-hole 351, through which the second lead screw 37 passes. The second base 31 is provided with a back plate 38 with a second disc 36. The second disc 36 and the second lead screw 37 form a second transmission structure 6. Rotation of the second disc 36 drives the second lead screw 37. The design of the lead screw and transmission structure makes operation simple and intuitive, improving work efficiency. Furthermore, the horizontal and vertical adjustment design of the movable portion 1 facilitates flexible adjustment of the position of the repair portion 4. It is suitable for motors of different models and specifications, making it highly versatile and meeting the needs of various application scenarios.
[0022] The repair part 4 includes a motor 44, a polishing wheel 45 and a vertical plate 41, and the vertical plate 41 is installed on the second nut 35; the upper and lower ends of the vertical plate 41 extend into upper arm plates 43 and lower arm plates 42 to fix the motor 44, and the upper arm plate 43 is provided with a through hole, and the rotating shaft of the motor 44 passes through the through hole and is connected to the polishing wheel 45, which is used to repair the slip ring in motion, and can ensure that the repair effect meets the expected standards, extend the service life of the motor, and reduce the occurrence rate of failures.
[0023] An insulating pad 46 is provided on the back of the vertical plate 41 of the repair part 4. When the vertical plate 41 is installed on the second nut 35, an insulating screw 47 with an insulating rubber sleeve is used to insulate the current generated on the slip ring, ensuring that there is no current in the moving part 1, thereby improving safety.
[0024] The first base 21 of the transverse moving part 21 is provided with a first slide rail 29, and the second base 31 of the longitudinal moving part 31 is provided with a second slide rail 39, which are used to reduce friction between components, extend the service life of mechanical components, and reduce maintenance costs.
[0025] The lateral movement unit 21 and the lateral movement unit 22 are each equipped with a first sliding rod 271 and a second sliding rod 371, respectively, which are the same length as the lead screw. These sliding rods are arranged parallel to the threaded axis, effectively increasing support for the mobile base and reducing the load on the threaded axis, preventing tilting or shaking during position adjustment and ensuring smoother operation of the entire system. They also provide good guidance for the mobile base, reducing resistance during movement and ensuring smoother and more efficient adjustment.
[0026] The first transmission structure 7 and the second transmission structure 6 are both gear meshing structures, which are used to achieve efficient and stable power transmission, reduce energy loss, and ensure accurate adjustment of the moving part 1.

[0028] The moving part 1 is also provided with a corresponding fixed base 5 for providing a stable support for the moving part 1 to ensure that the system does not shake or shift during the movement, thereby improving the operational stability of the entire device.
[0029] The fixed base 5 is provided with a level 51 for real-time monitoring of the horizontal state of the device to ensure that the fixed base 5 and the entire device always remain horizontal, thereby ensuring stable operation of the moving part 1 and the repairing part 4.
[0030] The fixing base 5 is provided with a fixing bolt 52 at the front end and a U-shaped fixing portion 53 at the rear end, which is used to ensure that it is firmly fixed on different work platforms or equipment, ensuring that the entire device will not loosen or shift during operation, thereby increasing the stability of the device.
[0031] There are multiple fixing bolts 52 and multiple U-shaped fixing parts 53 , which are used to enhance the fixing effect of the fixing base 5 .
[0032] During use, the repair device is first fixed near a running synchronous motor using the fixing bolts 52 and the U-shaped fixing portion 53 on the fixing base 5. Then, the power supply of the motor 44 of the repair unit 4 is turned on, causing the polishing wheel 45 to rotate. The position of the movable portion 1 is then adjusted using the wheel discs. The position of the transverse movable portion 21 is adjusted by rotating the first wheel disc 26, and the position of the longitudinal movable portion 31 is adjusted by rotating the second wheel disc 36. This allows the polishing wheel 45 to reach the designated worn position of the slip ring for repair.
[0033] By adopting the above-mentioned technical solution, the wear repair device for synchronous motor slip rings in motion of the present invention is provided with a movable portion 1 that can be adjusted laterally and longitudinally, thereby flexibly adjusting the repair position, and can accurately locate and repair the worn parts of the motor slip rings, adapting to motors of different models and specifications, thereby enhancing the versatility and adaptability of the device.

In addition, the structural design is simple, the operation is convenient, and maintenance is convenient, which improves the user experience and work efficiency.
