Abstract
The invention discloses a speed reduction drive system provided with damping gears and an air pressure balance structure and used for a stereo garage. The speed reduction drive system comprises a motor and a speed reducer. A rotor shaft of the motor extends into a shell of the speed reducer. The first gear, the third gear and the fifth gear of the speed reducer each comprise an inner ring body, an outer ring body and damping blocks. An automatic vent valve is arranged at the top of the shell of the speed reducer. The rotor shaft of the motor directly extends into the shell of the speed reducer to be in meshed transmission with a cylindrical gear transmission mechanism, so that the structure of the speed reducer is simplified, the size is smaller, and the structure is more compact. Due to the fact that the damping blocks are arranged between each inner ring body and the corresponding outer ring body, in the gear meshing process, the gears bear impact loads, the damping blocks are elastically deformed, the gear damping effect is achieved, noise generated in the gear meshing process can be lowered, and the tooth breaking problem is solved; and when the air pressure in the shell of the speed reducer is larger than the sealing air pressure of the automatic vent valve, the automatic vent valve is opened, and the technical problem that lubricating oil leaks outside due to the increase of the air pressure can be solved.
