Description

Technical Field

[0001] The present invention relates to the technical field of motor equipment, and particularly to a motor coupling vibration damping device and its manufacturing process. Background Technique

[0002] In a motor system, due to the vibration and impact generated during the operation of the motor, it often has an adverse effect on the motor itself and its load equipment, such as reducing the service life of the equipment, affecting the operation accuracy and stability of the equipment, etc. To solve this problem, various vibration damping devices have been developed to absorb and disperse the vibration and impact generated during the operation of the motor.

[0003] Traditional motor vibration damping devices mostly use rigid connections or simple elastic elements for vibration damping. However, these methods have many deficiencies. Rigid connections cannot effectively absorb vibration energy and easily cause equipment damage; while simple elastic elements, although having a certain vibration damping effect, are prone to aging and deformation after long-term exposure to vibration and impact, thus affecting their vibration damping performance.

[0004] In addition, traditional vibration damping devices are often relatively complex in structure, not convenient for assembly, disassembly and maintenance, increasing the manufacturing cost and maintenance cost. At the same time, traditional vibration damping devices are relatively single in the vibration damping dimension and cannot effectively damp vibration in multiple dimensions such as axial and radial directions, and the vibration damping effect is limited.
