Function of awning gearbox

Gearbox has the following functions:
1. Acceleration and deceleration, which is often called variable speed gearbox.
2. Change the transmission direction, for example, we can use two fan-shaped gears to transmit force vertically to another rotating shaft.
3. Change the torque. Under the same power conditions, the faster the gear rotates, the smaller the torque on the shaft, and vice versa.
4. Clutch function: We can separate the engine from the load by separating two originally meshed gears. For example, brake clutch, etc.
5. Distribute power. For example, we can use an engine to drive multiple slave shafts through the main shaft of the gearbox, so as to realize the function of one engine driving multiple loads.
