[0022] Embodiment: Reference Figures 1-4The illustrated combined anti-resonance motor end cover bearing structure includes an end cover 1, which is the base component of the entire structure and serves to support and fix other components. An empty slot 14 is provided on the inner side of the end cover 1. The function of the empty slot 14 is to provide installation space for the bearing body 4, so that the bearing body 4 can be stably installed on the inner side of the end cover 1, ensuring smooth connection and rotation between the motor rotating part and the end cover 1. The inner wall side of the empty slot 14 is provided with a bearing body 4. The bearing body 4 is one of the key components for the rotation of the motor, which can reduce the friction between the motor shaft and the end cover 1, allowing the motor shaft to rotate flexibly and ensuring the normal operation of the motor. The end cover 1 is provided with a protective shell 2 on both sides. The protective shell 2 mainly serves to protect the internal components, preventing external impurities, dust, etc. from entering the motor and affecting the normal operation of the motor. The side of the protective shell 2 is fixedly connected with a vibration pad 8 made of butyl rubber. Butyl rubber has good shock absorption performance. The vibration pad 8 can effectively reduce the vibration generated during the operation of the motor, avoid damage to other components of the motor caused by vibration, improve the stability of the motor operation, and the outer side of the end cover 1 is provided with a groove 9 matched with the vibration pad 8. The function of the groove 9 is to accurately install the vibration pad 8 on the end cover 1 and keep it stable during the operation of the motor, without displacement. The outer side of the protective shell 2 is provided with a clamping assembly. The clamping assembly includes a plurality of clamping blocks 7 fixedly connected with the inner wall side of the protective shell 2. The outer side of the bearing body 4 is provided with a plurality of clamping grooves 10 matched with the clamping blocks 7. The clamping blocks 7 and the clamping grooves 10 cooperate to firmly connect the protective shell 2 and the bearing body 4 together, preventing the protective shell 2 from loosening during the operation of the motor, and further enhancing the stability of the entire structure. The outer side of the protective shell 2 is provided with a plurality of slot holes 11. The inner wall side of the slot hole 11 is rotatably connected with a twisting rod 5. The function of the twisting rod 5 is to realize the operation of the threaded rod 6 by rotating, which is convenient for users to install and disassemble the connection between the protective shell 2 and the end cover 1. One end of the twisting rod 5 is fixedly connected with a threaded rod 6. The outer side of the end cover 1 is provided with a threaded groove 13 matched with the threaded rod 6. When the twisting rod 5 is rotated, the threaded rod 6 will rotate with it. The threaded rod 6 cooperates with the threaded groove 13 to tightly fix the protective shell 2 on the end cover 1, ensuring that the protective shell 2 will not fall off during the operation of the motor. The inner side of the end cover 1 is provided with a plurality of heat conduction holes 12. The inner wall side of the heat conduction hole 12 is fixedly connected with a heat conduction rod 3 made of red copper. Red copper has good heat conductivity. The heat conduction rod 3 can transfer the heat generated during the operation of the motor through the heat conduction hole 12, effectively reducing the temperature inside the motor, avoiding damage to the motor due to overheating, and improving the service life and working efficiency of the motor. The protective shell 2 is made of cast iron material. Cast iron material has high strength and hardness, which can ensure that the protective shell 2 plays a protective role while maintaining stable structure and being not easy to deform and damage.

[0023] In the embodiment, the bearing body 4 is installed in the empty slot 14, the anti-dragging shell 2 is dragged to make the anti-vibration pad 8 clamped in the groove 9, the clamping block 7 is clamped with the corresponding clamping slot 10, the anti-dragging shell 2 is limited and fixed by dragging the torsion rod 5 to make the threaded rod 6 threaded with the corresponding threaded slot 13, another anti-dragging shell 2 is installed by the same operation of installing the anti-dragging shell 2, and the bearing body 4 is limited and installed, and the end cover 1 is cooled by the plurality of heat-conducting rods 3.
