The meshing between gears achieves the effect of reducing speed and increasing rotational force. The use of energy-saving brushless DC motor drive can make the overall operation of the motor more energy-efficient.

This application utilizes an oil supply mechanism and a hook-pull mechanism. When the planetary gear reduction motor drives the pull rod to move to the bottom of the casing, the hook-pull mechanism hooks the pull rod and drives the piston to move. The piston sucks the lubricating oil into the oil storage tank. When the planetary gear reduction motor moves through the hook-pull mechanism, the hook-pull mechanism releases the pull rod, and the first elastic member pushes the piston to move and reset. The piston slowly squeezes the lubricating oil in the oil storage tank through the oil drain hole and lubricates the gears, thereby reducing the friction loss between the gears; Prior art 2 (publication number CN218940869U, a Chinese patent published on April 28, 2023) A planetary gear reduction motor, the planetary gear reduction motor includes a sun gear, a first connecting shaft is fixedly connected to the center of the sun gear, and the outer gear ring of the sun gear is evenly meshed with three inner planetary gear reduction motors, a first buffer gasket is slidably installed on one side of the sun gear, and an output gear disk is slidably installed on one side of the first buffer gasket, and the outer sides of the three inner planetary gear reduction motors are meshed with outer planetary gear reduction motors.
