Sideband components of mesh harmonic frequencies are dynamically characterized by using a single-degree-of-freedom nonlinear model of a cylindrical gear pair. Time-varying mesh stiffness and tooth surface form are formulated in the model. In addition to mesh harmonic components, the first order of gear rotation is incorporated into each of the time-varying mesh stiffness and the tooth surface form as the effect of run out error. This model presents that the product of mesh harmonics and low order component of gear rotation frequency produces sidebands on either side of the mesh frequency. Then, the equation of motion was numerically integrated. The calculated results prove the existence of asymmetrical property of sidebands of mesh frequency. Finally, these sideband characteristics are verified by the experiment using a single-stage helical gearing.
