The groove pulley is characterized by high mechanical efficiency and is mainly used in mechanical engineering.

The structure of the sheave structure is relatively simple, and the size in terms of appearance is relatively small. Because of the high mechanical efficiency, it is mainly used in the field of mechanical engineering. And it can perform indexing more smoothly and intermittently. But because of the flexible impact in the transmission fashion, it is often used in occasions where the speed is not too high.

Generally, the grooves on the sheave wheel are evenly distributed and are used to transmit the movement between the parallel shafts. Such a sheave wheel mechanism is called an ordinary sheave wheel mechanism. Some special forms of groove pulley are also used in some machines.
