ABSTRACT:
A configuration for a synchronous drive belt and pulley combination wherein each belt tooth has at least part of its fore and aft flank surfaces shaped in cross-section as the arc of a circle the radius of which is centered on the pitch line of the belt a distance W apart. Each tooth-engaging pulley cavity has at least part of its fore and aft surfaces shaped in cross-section as the arc of a circle the radius of which is centered on the pitch circle. The tips of the belt teeth and the bases of the pulley cavities are relatively shaped such that upon engagement of the belt with the pulley compressive stress is exerted from each cavity base through each engaging belt tooth.
