Variable Pitch Sheaves
5 through 30 HP
Wide Variable Speed Belts
    The Lovejoy Adjusta-Sheave can be a cost-saving alternative to a spring-loaded pulley when speed change is infrequent, such as with seasonal or long-running applications. To change speeds the drive is shut down, the belt removed, and the pitch diameter is set by means of an internal adjusting screw. Set-up is simple because the nameplate has a dimension chart that relates the flange separation to the pitch diameter where the belt will be positioned. The Adjusta-Sheave design incorporates features of the Hexadrive series, eliminating the need for internal drive keys, thus providing more efficient transfer of power and longer life. There are two methods of speed change with the Adjusta-Sheave: it can be used in place of the spring-loaded driver pulley, running to a fixed diameter companion sheave; or it can be used as the driven companion with a two-side moveable spring-loaded driver pulley. This second method actually increases the speed ratio of a drive package, because it can be broadened by changing the pitch diameter of the driven Adjusta-Sheave to extend the high and low speed limits. Both methods are adjustable center drives, requiring use of an adjustable motor base.
