Abstract
A V-ribbed belt for a mechanical power transmission is disclosed. The V-ribbed belt comprises an outer back-side surface, an inner front-side surface, and a load-carrying section disposed between the front-side and back-side surfaces. The front-side surface includes a plurality of laterally spaced longitudinally extending v-ribs. The back-side surface includes a plurality of raised features that, when running on a flat-faced, back-side pulley, form a contact patch of about 20% to about 50% of that of a traditional flat-faced belt running on a flat-faced pulley. The reduced contact patch provides increased contact pressure which in turn provides an improved effective coefficient of friction between the belt and the pulley.
