The role of gearbox
1, reduce the speed at the same time increase the output torque, torque output ratio by motor output by the reduction ratio, but be careful not to exceed the rated torque of the reducer;
2. The speed reduction reduces the inertia of the load at the same time, and the inertia reduction is the square of the reduction ratio. We can see that the general motor has an inertia value.
Gearbox use
1. Acceleration and deceleration is the so-called speed change gear box;
2. Change the direction of the drive. For example, we can use two sector gears to transfer the force vertically to another axis of rotation.
3. Change the rotating torque. Under the same power conditions, the faster the gear speed is, the smaller the torque is, and vice versa;
4. Clutch function: We can achieve the purpose of separating the engine from the load by separating the two originally engaged gears, such as the brake clutch;
5. Distribute power, for example, we can use an engine to drive multiple slave shafts through the gearbox main shaft, so as to realize the function of one engine driving multiple loads.
