BELT DRIVE INCLUDING TOOTHED BELTS AND TOOTHED PULLEYS OF IMPROVED TOOTH CONFIGURATIONS Abstract of the Disclosure A positive drive power transmission belt of integral unitary construction has a body of flexible resilient material that includes a plurality of driving teeth that are of substantially uniform cross section and which extend generally transversely thereof. An endless tensile member within the resilient material is disposed substantially on the dedendum line of the teeth. Each tooth has a crown that is at a distance furthest from the tensile member and a root that is at a distance nearest to the tensile member and has a width greater than the width of the crown. Opposite flanks extend from the ends of the crown to the ends of the root with each flank including a fillet adjoining the root. The fillet has an outer surface area which is at least 40-60% of one half of the total outer surface area of the tooth to increase the shear resistance of each tooth.
