Abstract

Chain noise, which is one of the influential factors to motorcycle pass-by noise regulation, can be classified into two categories: low frequency noise from the rear wheel originated from cordal action according to the second order component of chain meshing and high frequency noise generated by the impact when a chain roller contacts the sprocket bottom. A shape improvement using a urethane resin damper mounted on the drive sprocket and a steel roller drive chain with a urethane resin roller were effective for noise reduction, respectively. The new chain system that combined these new ideas has been proven to be capable of reducing the chain noise to half that of a conventional system.
