Lovejoy offers the most complete line of non-enclosed variable speed belt drives from fractional to 30 hp. Each component is made with the quality and reliability that Lovejoy builds into all of its power transmission products. Variable speed belt drives achieve the versatility needed to maximize application efficiency and productivity while remaining an inexpensive solution. In a typical installation, a belt connects a variable speed pulley to a driven sheave. The pulley is mounted on a motor shaft and the motor is at constant speed. Thus, the speed at the driven shaft is a ratio of the pitch diameters of the pulley and sheave. |
