[0002] A gearbox is a common mechanical transmission device that realizes the transmission of rotational speed and torque through the meshing between gears of different sizes. It is widely used in motors. The gearbox can have functions such as accelerating and decelerating, changing the transmission direction, and changing the driving torque. A gearbox is a device that uses gears to change the transmission state of an engine.
