What are the uses of reduction gearbox introduced by the foundry

What are the uses of reduction gearbox introduced by the casting manufacturer below
1. Acceleration and deceleration, commonly known as a variable speed gearbox
2. Change the transmission direction, for example, we can use two sector gears to vertically transmit force to the other rotating shaft
3. Change the rotational 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 meshing gears, such as brake clutch
5. Power distribution. For example, we can use an engine to drive multiple slave shafts through the gearbox spindle, thereby achieving the function of one engine driving multiple loads
The working principle of the gearbox:
Gearboxes are used for speed change, and gearboxes or reducers are mostly changed through gears. In simple terms, the principle is a large gear with a gear or a small gear with a large gear
