The gearbox has the following functions:
1. Acceleration and deceleration, which is often referred to as gearbox.
2. Changing the direction of transmission, for example, we can use two sector gears to transfer force vertically to another rotating shaft.
3. Change the moment of rotation. Under the same power condition, the faster the speed of the gear, the smaller the moment of the shaft, and vice versa.
4. Clutch function: We can separate the engine from the load by separating two meshing gears. For example, brake clutch.
5. Distribution of power. For example, we can use an engine to drive multiple slave shafts through the gearbox spindle, thus realizing the function of one engine to drive multiple loads.
