Abstract
A silent chain having multiple links each having a pair of teeth and apertures, which are connected by connecting pins inserted into the apertures. The links have an sheared link bearing surface which further reduces the wear of the sprocket tooth surface and further prevents defective bending of the silent chain. The bearing surface of the link tooth has a shear surface which may be formed by shaving or fine-blanking. The shear surface length may be at least approximately 70% or at least approximately 90% of the link thickness.
