What happens when the pulley becomes smaller and smaller
The same proportion is reduced, the output speed will not change, it will increase the bending of the belt and reduce the life of the belt. It reduces the load capacity, the reduction of the amount of computation, because the belt is driven by friction, the pulley decreases, and the friction surface decreases.
If it's not the same proportion, it's more complicated. In general, the output speed is bound to change, depending on whether the output speed is higher or lower depending on the percentage of the reduction of the main moving pulley. This is a lot of the disadvantages of scaling down.
Also have the advantage, the material is saved, the processing quantity is reduced. If it is too small, it may be more difficult to process. The weight is reduced and the space for installation is small.
