ABSTRACT:
A belt drive system for use in a positive drive application includes a transmission belt having a row of drive teeth spaced apart along a first side and a non-toothed opposite second side. The system includes a driver pulley, a counter-rotating driven pulley or pulleys, and the transmission belt. The counter-rotation is achieved by the incorporation of a 180 degree twist in a belt span between the driver pulley and the driven pulley and a recovery twist in a second belt span from the driven pulley back to the driver pulley.
