In this study, an analytical formulation of the dynamic behaviour of a spur gear pair is derived. A two-step mesh stiffness model is assumed to account for the time-varying stiffness during tooth engagement. The tooth error model proposed by Kasuba et al. is employed to characterise the tooth error effect on the transmitted torque spectrum. The analytic frequency spectrum of the transmitted torque is formulated by using the corresponding Fourier series. Numerical results have shown that the frequency spectra of the transmitted torque are dominated by the mesh stiffness alternation and the contact ratio of the mating gear pair. Furthermore, the amplitude and frequency modulations introduced by a harmonic input torque and tooth profile error have also been studied.
