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.
L'invention porte sur une courroie trapézoïdale crantée pour la transmission d'énergie mécanique. La courroie trapézoïdale crantée comprend une surface postérieure extérieure, une surface antérieure intérieure et une section de support de charge disposée entre les surfaces antérieure et postérieure. La surface antérieure comprend une pluralité de crans trapézoïdaux s'étendant longitudinalement et espacées latéralement. La surface postérieure comprend une pluralité d'éléments saillants qui, lorsqu'ils s'étendent sur une poulie à face plate côté arrière, constituent un élément de contact d'environ 20 % à environ 50 % par rapport à une courroie à face plate classique s'étendant sur une poulie à face plate. L'élément de contact réduit assure une pression de contact accrue qui à son tour apporte un coefficient de frottement efficace amélioré entre la courroie et la poulie.
