ABSTRACT:
In a positive drive power transmission system composed of a toothed belt and two or more pulleys, operating noise resulting from the impact of the belt and the pulleys is dramatically reduced by having surface discontinuities on either the belt or on the pulleys on those surfaces where the belt and the pulleys engage in impact contact when in operation. The surface discontinuities may be formed by recessed or raised portions of the belt or pulleys, may be straight or curved, and may be substantially parallel to the tensile member or at an angle thereto. Several methods of manufacturing belts with such surface discontinuities are disclosed.
