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.

Counter-rotational drive belt system and method

A drive system comprising a driver pulley, a driven pulley ( ), and a belt ( ). The belt ( ) has a pulley engaging surface ( ) comprised of a plurality of transversely extending self-tracking teeth ( ). The driven pulley ( ) has a non-grooved, crownless belt engaging surface ( ). The material ( ) forming the pulley engaging surface ( ) of the belt ( ) having a relatively low coefficient of friction, and the material ( ) forming the belt engaging surface ( ) of the driven pulley ( ) having a relatively high coefficient of friction.
