The gearbox has the following functions:
1. Accelerating and decelerating is the so-called variable speed gearbox.
2. Change the transmission direction. For example, we can use two sector gears to transmit the force vertically to the other rotating shaft.
3. Change the rotating torque. Under the same power condition, the faster the gear rotates, the smaller the torque on the shaft, and vice versa.
4. Clutch function: We can achieve the purpose of separating the engine from the load by separating the two originally meshed gears. Such as brake clutch and so on.
5. Distribution of power. For example, we can use an engine to drive multiple slave shafts through a gearbox main shaft, so as to realize the function of one engine driving multiple loads.
