Abstract:
A drive system comprising a driver pulley, a driven pulley (22), and a belt (10), the belt (10) having a pulley engaging surface (16) comprised of a plurality of transversely extending teeth (18) having a self-tracking profile causing the belt to track to only a single path when traveling on a correspondingly grooved pulley, and the driven pulley (22) has a non-grooved, crownless belt engaging surface (24), the combination being characterized by:the material (20) forming the pulley engaging surface (16) of the belt (10) having a coefficient of friction, the material (28) forming the belt engaging surface (24) of the driven pulley (22) having a coefficient of friction greater than the coefficient of friction of the pulley engaging surface (16) of the belt (10), and the dynamic coefficient of friction between the driven pulley (22) and the belt (10) is greater than a dynamic coefficient of friction between the driver pulley and the belt (10).
