Abstract
Description

[0002] During the long-term operation of an electric motor, in order to ensure its stability and safety, it is necessary to regularly monitor and maintain the condition of key components such as internal windings and bearings. In the existing technology, although some motor housings are equipped with observation windows, they are mostly fixed with screws or snap-fit structures. Disassembly requires special tools, and frequent disassembly and assembly can easily lead to seal failure or structural loosening.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0021] Example 1, referring to Figure 1-4 The first embodiment of this utility model provides a maintenance mechanism 1 including a housing 101 and an observation window 102. The inner wall of the housing 101 is in contact with the surface of the observation window 102. Limiting mechanisms 2 are provided on both sides of the observation window 102. A cooperating mechanism 4 is provided on the limiting mechanism 2. The limiting mechanism 2 is used to quickly disassemble and assemble the observation window 102, and the cooperating mechanism 4 is used to assist the disassembly and assembly process.
[0022] Specifically, the maintenance mechanism 1 effectively solves the problems of cumbersome disassembly and assembly, time-consuming process, and easy loosening of the traditional motor observation window 102 by setting a limiting mechanism 2 and a cooperating mechanism 4 between the outer shell 101 and the observation window 102. The limiting mechanism 2 realizes reliable locking and quick release of the observation window 102, while the cooperating mechanism 4 provides guidance and buffering during disassembly and assembly, ensuring smooth and stable operation. This structure not only improves maintenance efficiency, but also avoids sealing failure or structural damage caused by frequent disassembly, ensuring the sealing and safety of the motor during operation.
[0023] Furthermore, the motor housing is equipped with an observation window 102 to facilitate intuitive monitoring of the operating status of key internal components. The observation window 102 is reasonably laid out, covering the main functional areas, improving the safety and controllability of the equipment, and enabling quick assembly and disassembly through the limiting mechanism 2 and the cooperating mechanism 4.
[0024] Example 2, the second embodiment of this utility model, provides a limiting mechanism 2 including a fixing ring 201, a fixing block 202, a limiting rod 203, a stop block 204, and a connecting plate 205. The upper surfaces on both sides of the fixing ring 201 are fixedly connected to the surface of the fixing block 202. The inner wall of the fixing block 202 is fixedly connected to the upper end of the limiting rod 203. The inner wall of the limiting rod 203 contacts the surface of the stop block 204. The rear surfaces of the two stop blocks 204 are fixedly connected to the inner wall of the connecting plate 205. An auxiliary mechanism 3 is provided on the limiting mechanism 2. The auxiliary mechanism 3 includes a transmission block 301, an adjusting screw 302, a support frame 303, and a guide block 304. The inner wall of the transmission block 301 is threadedly connected to the surface of the adjusting screw 302. The two ends of the adjusting screw 302 are rotatably connected to the inner wall of the support frame 303. The surfaces of the two support frames 303 are fixedly connected to the two ends of the guide block 304. The inner wall of the fixing ring 201 is fixedly connected to the surface of the observation window 102. The surface of the limiting rod 203 is in contact with the inner wall of the outer shell 101. The stop block 204 and the connecting plate 205 are slidably connected to the inner wall of the outer shell 101 through a sliding groove. The inner wall of the connecting plate 205 is fixedly connected to the lower end of the transmission block 301. The lower end of the support frame 303 is fixedly connected to the surface of the outer shell 101. The inner wall of the transmission block 301 is slidably connected to the surface of the transmission block 301.
[0025] Specifically, the limiting mechanism 2, through the linkage of the fixed ring 201, the limiting rod 203, the stop block 204, and the connecting plate 205, combined with the threaded transmission of the adjusting screw 302 and the transmission block 301 in the auxiliary mechanism 3, achieves reliable locking and rapid release of the observation window 102. This solves the problems of difficult disassembly and assembly, inaccurate positioning, and easy loosening during operation in traditional structures. During maintenance, only the adjusting screw 302 needs to be driven to move the connecting plate 205, causing the stop block 204 to disengage from the slot of the limiting rod 203 and quickly release the lock. When the motor is running, the self-locking characteristic of the transmission ensures that the stop block 204 and the limiting rod 203 are tightly engaged, effectively preventing the observation window 102 from being accidentally opened due to vibration or external force, thus balancing maintenance convenience and operational safety.
[0026] Furthermore, when the connecting plate 205 is moved, the travel blocks 204 on both sides disengage from the slots of the limit rods 203 in the observation window 102, releasing the mechanical lock. The observation window 102 can be quickly disassembled for maintenance. The self-locking characteristic of the worm gear ensures that the travel blocks 204 and the limit rods 203 are stably connected when the motor is running, preventing the observation window 102 from opening accidentally and ensuring safety.
[0027] Example 3, the third embodiment of this utility model, provides a cooperating mechanism 4 including a transmission rod 401, a driving worm gear 402, a driven worm wheel 403, and a dustproof box 404. The surface of the transmission block 301 is fixedly connected to the surface of the driving worm gear 402. The tooth surface of the driving worm gear 402 meshes with the tooth surface of the driven worm wheel 403 for transmission. The surface of the driven worm wheel 403 is rotatably connected to the inner wall of the dustproof box 404. The surface of the transmission rod 401 is rotatably connected to the inner wall of the dustproof box 404. The driving worm gear 402 and the driven worm wheel 403 are disposed inside the dustproof box 404. The surface of the driven worm wheel 403 is fixedly connected to the outer end of the adjusting screw 302. The surface of the dustproof box 404 is fixedly connected to the surface of the outer shell 101.
[0028] Specifically, the cooperating mechanism 4, through the transmission rod 401, the driving worm gear 402, the driven worm wheel 403, and the dustproof box 404, solves the problems of laborious operation, unreliable transmission, and susceptibility to dust interference in the traditional manual disassembly of the observation window 102. The transmission rod 401 drives the driving worm gear 402 to rotate, and the torque is transmitted to the adjusting screw 302 through the meshing of the worm gear and worm wheel, realizing the smooth axial movement of the transmission block 301, which in turn drives the connecting plate 205 and the stop block 204 to move. The entire transmission process is enclosed in the dustproof box 404, effectively isolating external impurities from intrusion and ensuring the long-term stable operation of the mechanism. At the same time, the worm gear pair has a self-locking characteristic, which can prevent malfunctions without additional locking, improving the convenience, safety, and reliability of disassembly and assembly of the observation window 102.
[0029] Furthermore, when overhauling the motor, the operator rotates the transmission rods 401 with anti-slip textures on both sides, which drives the active worm gear 402 to rotate, meshing with the driven worm wheel 403, causing the adjusting screw 302 to rotate, driving the transmission block 301 to move axially, and causing the connecting plate 205 to slide in the groove.
[0030] Working Principle: During daily use, the motor housing surface is equipped with multiple observation windows 102, allowing operators to intuitively monitor the operating status of key internal components. These observation windows 102 not only provide a visual inspection channel but also lay the foundation for subsequent maintenance work. The positions of the observation windows 102 are rationally arranged to ensure coverage of the main functional areas inside the motor, thereby improving the safety and controllability of equipment operation. When internal maintenance of the motor is required, the operator first rotates the transmission rods 401 located on both sides of the motor housing. The surface of the transmission rods 401 is provided with anti-slip texture to enhance friction during manual operation and is fixedly connected to the driving worm gear 402 inside the dustproof box 404. Rotating the transmission rods 401 will drive the driving worm gear 402 to rotate synchronously, thereby engaging with the driven worm wheel 403 for transmission. Coaxially fixed with the adjusting screw 302, its rotation directly drives the adjusting screw 302 to rotate. Under the action of the thread on the surface of the adjusting screw 302, the transmission block 301 that cooperates with it moves axially and drives the connecting plate 205 to slide smoothly in the preset slide groove in the motor housing. As the connecting plate 205 moves, the travel blocks 204 fixed on both sides of it are gradually pulled out from the slots of the limit rods 203 on both sides of the observation window 102, thereby releasing the mechanical lock on the observation window 102. At this time, the observation window 102 can be quickly disassembled, which is convenient for inspection or maintenance of the corresponding internal area. The entire unlocking process relies on the inherent self-locking characteristics of the worm gear. Under normal motor operation, even if subjected to vibration or external force interference, the connection between the travel block 204 and the limit rod 203 can still remain stable, effectively preventing the observation window 102 from opening accidentally and ensuring operational safety.
[0031] In summary, through the coordinated operation of components such as the transmission rod, driving worm gear, driven worm wheel, adjusting screw, transmission block, and travel block, the observation window achieves both visual functionality during daily monitoring and quick disassembly / reassembly during maintenance. Furthermore, the self-locking characteristic of the worm gear ensures the reliable fixation of the observation window during operation.
