  • Low backlash-high-torque power transmission system and toothed belt used therein
    Patent number: 4515577
    Abstract: A flexible power transmission belt having a plurality of teeth each of which has a pair of arcuate convex flank portions which in longitudinal cross-section closely approximate to an arc of a circle. Each tooth exhibits a height to width relationship within a predetermined range, and the arcuate flanks each have a pressure angle within a predetermined range. The belt is preferably used in combination with a toothed pulley whose teeth are substantially conjugate to the belt teeth and whose cavities between the teeth have a height to width relationship within another predetermined range and have concave flanks exhibiting a pressure angle in still another predetermined range, said belt tooth width being approximately 0.98 of the pulley cavity width so as to provide a high torque positive drive power transmission system having minimum backlash.
