Abstract

A sprocket for transferring a force between a chain and a drive element that includes a plurality of teeth and a plurality of openings proximate the teeth. Each tooth has a load-bearing flank and a non-load-bearing flank. One of the plurality of openings are arranged relative to one of the plurality of teeth, in one-to-one correspondence therebetween, such that the opening is asymmetrically divided by a radial centerline of the tooth, a first load strip is formed between the opening and the load-bearing flank of the tooth, and a second load strip is formed between the opening and the non-load-bearing flank of the tooth.
