Silent chain with raised link backs

摘要

A silent chain for power transmission applications wherein the chain is in sliding contact with a chain guide or tensioner. The chain is constructed of some link plates having a higher back than other link plates. In operation, the higher backed links slide against the chain guide or tensioner while the lower backed links do not contact the chain guide or tensioner. Because not all of the links slide against the chain guide, the friction between the chain and chain guide is reduced.
