Description

Technical Field

[0001] The utility model relates to the technical field of motor accessories, and more specifically, to a motor end cover. Background Art

[0002] In the field of motor design and application, the motor end cover is an important motor component, and its performance and reliability directly affect the overall performance and service life of the motor. First of all, the existing motor rear end cover usually has heat dissipation holes to promote the dissipation of heat inside the motor and ensure the normal operation of the motor. However, although this design meets the motor heat dissipation needs to a certain extent, it also introduces moisture and water vapor into the motor. The existence of the heat dissipation holes greatly reduces the moisture-proof performance of the motor. Moisture and water vapor can easily enter the motor through the heat dissipation holes, which has an adverse effect on the insulation performance and components of the motor. In the long run, the reliability and service life of the motor will be greatly reduced, and may even cause serious safety hazards.

[0003] Secondly, during the motor assembly and maintenance process, there are certain problems in the connection operation between the rear end cover of the motor and the motor body. In the prior art, the installation and disassembly process of the rear end cover and the motor body is relatively cumbersome and time-consuming, which not only increases the labor intensity of the assembly workers, but also affects the production efficiency. When repairing and replacing the end cover of the motor, the cumbersome disassembly and assembly process also brings inconvenience to the maintenance personnel, prolongs the downtime of the equipment, and affects the production progress.

[0004] In addition, in order to improve the moisture-proof performance of the motor, some existing technologies have adopted a solution of installing a moisture-proof device on the outside of the rear end cover. This design has alleviated the problem of moisture entering the motor to a certain extent, but the installation method of the moisture-proof device still has room for improvement. Usually, the moisture-proof device and the rear end cover are connected with fasteners such as bolts and nuts. This connection method has problems such as inconvenient installation and disassembly and low efficiency. At the same time, the bolt and nut connection also increases the installation complexity of the moisture-proof device and increases the production and maintenance costs. Summary of the invention

[0030] In this embodiment, when the motor is in normal use, the sealing strip 16 can prevent external moisture and water vapor from penetrating from the connection between the main body 2 and the end cover 1. When the external moisture enters the storage bin 13 through the filter hole 15, the activated carbon placed in the storage bin 13 will adsorb the moisture in the air to prevent it from entering the motor through the heat dissipation hole 12. The heat dissipation hole 12 is mainly used to improve the heat dissipation performance of the motor.

[0036] More specifically, when it is necessary to replace the adsorbent such as activated carbon in the placement bin 13, the card plate 19 is pressed with one hand so that the card plate 19 does not move, and then the rotating frame 18 is rotated by the handle 32, so that the rotating frame 18 rotates under the limit of the annular groove 25. At the same time, the rotating frame 18 cooperates with the fixed block 31 to compress the first spring 30, and then the rotating frame 18 drives the spiral groove 27 opened on the outside to rotate. Due to the limit of the guide block 28 and the guide groove 29, the support plate 24 will not rotate with it, and then the limiting ball 26 will slide relatively in the spiral groove 27, thereby driving the support plate 24 to move up and down on the outside of the rotating frame 18.

After the replacement is completed, the placement bin 13 and the mounting plate 14 are re-fixed on one side of the end cover 1 according to the above operation.

[0037] In summary, when the overall equipment is in use or running: when the motor is in normal use, the sealing strip 16 can prevent external moisture and water vapor from penetrating from the connection between the main body 2 and the end cover 1; when external moisture enters the placement bin 13 through the filter hole 15, the activated carbon placed in the placement bin 13 will adsorb moisture in the air to prevent it from entering the motor through the heat dissipation holes 12; the heat dissipation holes 12 are mainly used to improve the heat dissipation performance of the motor; when the end cover 1 needs to be removed to maintain or replace the internal components of the motor, first press the fixed plate 5 with one hand to prevent the fixed plate 5 from rotating; then rotate the movable rod 4 through the handle 17 set at the top of the movable rod 4; then the movable rod 4 will rotate in the movable sleeve 6 and drive The reducing groove 11 opened on the inner side rotates. Due to the special structural design of the reducing block 10 and the reducing groove 11, and the limiting of the clamping rod 7 by the through groove 9 and the clamping groove 8, when the reducing block 10 slides in the reducing groove 11, it will drive the clamping rod 7 to slide in the through groove 9 and gradually move toward the inside of the movable sleeve 6. When the movable rod 4 can no longer rotate, the clamping rod 7 has been completely disengaged from the clamping groove 8, and one end of the clamping rod 7 is flush with the outside of the movable sleeve 6. Then, the handle 17 is pulled outward to pull the movable rod 4 and the movable sleeve 6 out of the plug-in sleeve 3, and then the end cover 1 is removed from one side of the main body 2. After the maintenance and replacement of the internal components of the motor are completed, the end cover 1 can be reinstalled on one side of the main body 2 with reference to the above process.

[0038] When it is necessary to replace the adsorbent such as activated carbon in the placement bin 13, the card plate 19 is pressed with one hand so that the card plate 19 does not move, and then the rotating frame 18 is rotated by the handle 32, so that the rotating frame 18 rotates under the limit of the annular groove 25. At the same time, the rotating frame 18 cooperates with the fixed block 31 to compress the first spring 30, and then the rotating frame 18 drives the spiral groove 27 opened on the outside to rotate. Due to the limit of the guide block 28 and the guide groove 29, the support plate 24 will not rotate with it, and then the limiting ball 26 will slide relatively in the spiral groove 27, thereby driving the support plate 24 to move up on the outside of the rotating frame 18. Due to the special structural design of the guide block 28 and the guide groove 29, the support plate 24 will drive the flexible plate 20 to shrink inward through the mutual limitation of the guide block 28 and the guide groove 29, so that the snap-in plate 22 is disengaged from the snap-in groove 21. When the handle 32 can no longer rotate, the handle 32 and the snap-in plate 19 are pulled outward together, and the flexible plate 20 and the snap-in plate 22 can be pulled out of the snap-in sleeve 23. Then the placement bin 13 is removed from one side of the end cover 1, and the activated carbon in the placement bin 13 is replaced.
