Abstract

A toothed plate-link chain having a plurality of link plates that form chain links in the transverse direction of the chain. The link plates of laterally adjacent chain links partially overlap, and the chain links are hingedly connected to each other by hinge pins that extend through receiving openings in overlap regions of the link plates. At least some of the link plates have plate teeth, and some of the link plates have a modified form to reduce the effect of impact impulses of the link plates on the tooth flanks of a toothed wheel about which the chain passes. As a result, the magnitude of the meshing impulses and the times during which they act on the toothed wheel are modified to thereby reduce structure-borne noise.
