Variable Pitch Sheaves, one of the main categories of sheaves, is used to allow for mechanical drive variations. The main principle used in variable pitch sheaves is using threaded
angular faced discs with V-grooves that are movable. When you move the discs closer to each other, the belt will ride higher in the groove. This means that the pitch diameter of the sheave increases and the speed of the driven drive will be higher. The reverse is true when the discs are moved away from each other. Variable sheave drives are very important in power mechanics because they provide a simple method of varying speed of motors
for various applications affordably. If you were to use a fixed-pitch model, a number of sheave combinations would be required. This is time-consuming and expensive. But the variable sheaves are economical, easy to install and adjust. To see the different types of variable sheaves you can use in your facility, make sure to visit our page.
