ABSTRACT:
A sprocket wheel has a plurality of equi-spaced circumferential teeth, each pair of adjacent teeth defining therebetween a pocket. The pockets are shaped to engage with the links of a drive chain. The teeth are formed with flanks at their edge faces which lead and trail during rotation of the sprocket wheel. The flanks merge with rounded faces which define bases of the teeth. The teeth are asymmetrically shaped in such a manner that the rounded faces associated with leading flanks each have a radius of curvature which is greater than the radius of curvature of each of the rounded faces associated with trailing flanks.
