To investigate the dynamic behaviors and noise radiations of face gear drives

a calculation procession of noise radiations of face gear drives

which is based on lumped mass method

finite element method (FEM) and boundary element method (BEM)

was proposed. Furthermore

a noise radiation of an example case was simulated

and the influences of base geometric parameters and operating conditions on noise radiations of face gear drives were discussed. The analytic results indicate increasing module and drive ratios would benefit to reduce noise radiations

and pressure angles would be insensitive for noise radiations

et al. These contributions would be helpful to improve the design of face gear drives associated with low noise radiations.
