Abstract
A roller chain timing drive reduces noise by thinning the teeth and elongating the root land in between each pair of teeth. Specifically, through detailed calculation, the root land is elongated resulting in a reduced thickness of the teeth as measured across itself from a drive flank to a coast flank. The result is maintained contact of all rollers wrapped around a sprocket throughout the entire design life of the chain and sprockets which reduces noise.
