ABSTRACT:
In a silent chain having interleaved guide rows and joint rows, guide plates at the outer sides of the guide rows are connected by engagement pins which extend through overlapping recesses formed on the outer flanks of the guide row plates, and on the inner flanks of the joint row plates. The engagement pins contact sprocket teeth before the outer flanks of the guide row plates contact the sprocket teeth. Cutouts formed in the guide plates adjacent the engagement pins allow the guide plates to deform and thereby absorb the impact imparted to the engagement pins by the sprocket teeth.
