Chain and sprocket assembly to provide improved NVH reduction

摘要

A chain and sprocket assembly for transmitting torque between at least a first and a second shaft, comprising: a number "m" of identical chains, where a) "m" corresponds to at least two (2), and b) each chain comprises at least two types of chain links c) the different links are arranged in an identical arbitrary predetermined set pattern that repeats with at least one revolution (T) of each chain, a number "m" of identical sprockets on each shaft the chains are angularly misaligned with each other on the corresponding sprocket and the sprockets on each shaft have a number L of teeth and the teeth are angularly misaligned with each other by 2n / Lm rad.
