Traditional motor end covers have simple structures and poor vibration damping. The vibrations generated during motor operation not only affect the motor's lifespan but may also increase operating noise and potentially cause loosening of connections between the motor and other equipment, posing safety hazards.

Therefore, in order to address the above problems, a motor end cap with vibration damping grooves is proposed. Utility Model Content

[0025] Reference Figure 1-4As shown, this utility model provides a technical solution: a motor end cover with vibration damping grooves, including a motor end cover body 1, a shaft hole 2 at the center of the motor end cover body 1, six vibration damping grooves 5 in the inner cavity of the motor end cover body 1, four mounting plates fixedly connected to the surface of the motor end cover body 1, and screw holes 4 in the surface of the mounting plates for mounting the motor end cover body 1 to the motor, and an elastic buffer layer 6 fixedly connected to the inner wall of the vibration damping grooves 5. The six vibration damping grooves 5 in the inner cavity of the motor end cover body 1, and the elastic buffer layer 6 on the inner wall of the vibration damping grooves 5, can effectively absorb the vibration energy generated during motor operation and reduce the vibration amplitude. At the same time, the four mounting plates with screw holes 4 ensure a stable connection between the end cover and the motor, improve the overall operational stability, reduce component wear caused by vibration, and thus extend the service life of the motor. Six reinforcing columns 7 are fixedly connected to the inner cavity of the motor end cover body 1, and the six reinforcing columns 7 are distributed in a circumferential array in the inner cavity of the motor end cover body 1. The six reinforcing pillars 7 arranged in a circumferential array within the inner cavity of the motor end cover body 1 significantly enhance the structural strength and rigidity of the end cover, effectively resisting mechanical stress and vibration impact during motor operation, reducing the risk of end cover deformation, improving the overall stability and reliability of the motor, and ensuring long-term stable operation. Sound-absorbing cotton 8 is fixedly connected to both sides of the reinforcing pillars 7. The sound-absorbing cotton 8 fixedly connected to both sides of the reinforcing pillars 7 effectively absorbs noise generated during motor operation, reduces the intensity of noise propagation outward, thereby improving the quietness of the motor's working environment and reducing noise pollution. Heat dissipation holes 9 are provided on the surface of the motor end cover body 1, arranged in a honeycomb array. The honeycomb array of heat dissipation holes 9 on the surface of the motor end cover body 1 significantly increases the heat dissipation area, optimizes the airflow path, accelerates the dissipation of heat generated during motor operation, effectively reduces the internal temperature of the motor, avoids performance degradation or failure due to overheating, and improves the motor's working efficiency and service life. Several heat dissipation fins 10 are fixedly connected to the surface of the motor end cover body 1, arranged in a circumferential array. The heat dissipation fins 10 distributed in a circumferential array on the surface of the motor end cover body 1 increase the heat dissipation surface area and enhance the heat exchange efficiency with the air. This allows the heat generated by the motor operation to be quickly dissipated into the surrounding environment, effectively reducing the motor temperature and preventing overheating damage to internal components. This, in turn, improves the stability of the motor and extends its service life. A sound insulation layer 11, made of damping material, covers the outer surface of the end cover body at the position corresponding to the vibration damping groove 5. The damping material sound insulation layer 11 covering the vibration damping groove 5 on the outer surface of the end cover body can utilize the viscoelastic properties of the damping material to convert the sound energy generated by the motor vibration into heat energy for dissipation, further blocking noise transmission. Working in synergy with the vibration damping groove 5, it significantly improves the noise reduction effect, creating a quieter environment for motor operation and reducing noise interference to surrounding equipment and personnel. A threaded sleeve 12 is provided inside the screw hole 4, and the threaded sleeve 12 is interference-fitted with the screw hole 4.By setting a threaded sleeve 12 that is interference-fitted with the screw hole 4 inside the screw hole 4, the connection strength and stability between the motor end cover and the motor body can be significantly enhanced, and the bolts can be prevented from loosening due to vibration during motor operation.
[0026] Working principle: When the motor vibrates during operation, the six vibration-damping grooves 5 inside the motor end cover body 1 and the elastic buffer layer 6 on the inner wall absorb vibration energy through their own deformation, reducing the vibration amplitude; the six reinforcing columns 7 distributed in a circumferential array enhance the structural strength of the end cover, resist mechanical stress and vibration impact, and reduce the risk of end cover deformation; the sound-absorbing cotton 8 on both sides of the reinforcing columns 7 absorbs motor operating noise; the heat dissipation holes 9 distributed in a honeycomb array and the heat dissipation fins 10 distributed in a circumferential array significantly increase the heat dissipation area, optimize air circulation, accelerate heat dissipation, and reduce the motor temperature; the damping material sound insulation layer 11 at the vibration-damping grooves 5 on the outer surface of the end cover body converts vibration sound energy into heat energy for dissipation, further blocking noise; the threaded sleeve 12 with interference fit inside the screw hole 4 ensures a stable connection between the motor end cover and the motor body, preventing bolt loosening due to vibration. These structures work together to ensure stable, efficient, and low-noise operation of the motor.
