ABSTRACT:
A pulley drive system utilizes a driven pulley and a driving pulley and a belt connecting the pulleys. The driving pulley has spaced discs and there are means for varying the spacing between the discs to vary the speed of the belt driving the driven pulley. Speed sensing means are positioned adjacent the driven pulley to provide a signal representative of the speed of the driven pulley. The speed sensing signal is utilized in a regulating circuit to control the means for varying the spacing between the discs to thus control the speed of the belt.
