Abstract
This invention relates to power transmission belts having multiple longitudinally extending ribs, and particularly, to an improved belt with a cross sectional profile that includes a clearance space that connects adjacent ribs, curved opposing surfaces in the pulley contact area, and a curved rib apex. The inventive belts cross sectional profile design maximizes the performance of each region of the rib profile. The invention separates the rib profile design into three critical areas: the belts rib.backslash.pulley contact surfaces; the clearance space that connects adjacent ribs and separates the pulley apex from the root of the rib; and the belt rib apex. The improved power transmission belt overcomes piling and noise problems associated with previous belt designs.
