Abstract
A drive system comprising a driver pulley, a driven pulley (22), and a belt (10). The belt (10) has a pulley engaging surface (16) comprised of a plurality of transversely extending self-tracking teeth (18). The driven pulley (22) has a non-grooved, crownless belt engaging surface (24). The material (20) forming the pulley engaging surface (16) of the belt (10) having a relatively low coefficient of friction, and the material (28) forming the belt engaging surface (24) of the driven pulley (22) having a relatively high coefficient of friction.
Claims5
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).
