Drilling machines with belt drive

 

— a mechanism in the form of two or more wheels (pulleys) on which a belt is pulled. The main advantages of a belt drive are simplicity and low cost; at the same time, it is reliable enough for work of low and (in most cases) medium complexity. On the other hand, such a system takes up quite a lot of space and is poorly suited for high loads. Yes, and shifting speeds on a belt drive is not very convenient — usually you have to either change the pulley or rearrange the belt, which anyway requires removing the protective cover.
