The invention discloses an elastic damping device of a motor rotor. The damping device comprises a gear shaft, a damping disc, an elastic damping part and a wire winding disc, wherein multiple two-layer stepped involute curved-surface bodies are evenly arranged on the damping disc, the same number of one-layer involute curved-surface bodies are evenly arranged on the elastic damping part, and the same number of two-layer stepped involute curved-surface bodies are evenly arranged on the wire winding disc. The involute curved-surface bodies of the elastic damping part are arranged between two involute curved-surface bodies of the damping disc and the wire winding disc. The elastic damping device of the motor rotor is even in stress and stable in transmission, effectively diffuses rising temperature inside the disc by arranging an air flow channel, ensures decrease of motor inner resistance, improves the output efficiency, decreases faults, remarkably prolongs the service life of batteries and a driving range and can obtain good social and economic benefits.
Description
technical field [0001] The invention relates to a damping device, in particular to a rotor elastic damping device applied to motor drive. Background technique [0002] With the development of social industry, motor drive has played an increasingly important role in all walks of life. In the prior art, the high-speed motor transmits power through deceleration, has the characteristics of large starting torque, strong overload capacity, high operating efficiency, light weight, and less consumables, and has become the mainstream direction of electric bicycle drive technology. However, due to the large torque of high-speed deceleration, it is required to use high-strength steel gears. During operation, large noise has become the biggest disadvantage of motor operation. In order to solve this key problem, a more effective shock and noise reduction device technology is needed to achieve this goal. In the existing traditional structural technology, limited to the small space of th...
