Fixed Centre Drive

Swati offers Fixed Centre Drive brings stepless speed variation to numerous industrial applications where space saving and wide speed variation are essential considerations. The ratio of speed variation achieved is 1:6. It consists of two variable speed pulleys and a variable speed belt. Both the variable speed pulleys have two disks each, one fixed on the hub and other sliding. The driving pulley is the control pulley having bearing mounted on its sliding disc while the driven pulley has spring loaded sliding disc. The control pulley is provided with a manually adjustable speed control device. To vary the speed, the sliding disc of the control pulley is adjusted by means of the speed control device. Accordingly the variable speed belt is either pulled further in or further out of the control pulley. In turn, the spring-loaded pulley gets adjusted automatically to accommodate the belt. The drive works on a fixed centre distance and provides stepless speed variation.
