Prediction of the vibroacoustic behaviour of geared transmissions is generally based on determining the excitation sources, the overall modelling of the transmission, the modal analysis and the solving of the parametric equations of the motion generated by these models. On the building process of such large degrees of freedom models, the elastic coupling induced by the gear mesh is generally described by the meshing stiffness. Nevertheless, when the contact is established along the tooth width, the resulting moment can constrain the rotational angles associated to wheel tilting and flexural deformation of shafts. The scope of this study is to introduce the coupling terms between wheels associated to this phenomenum. One shows also on the basis of some examples in what manner they can influence the modal behaviour and the vibroacoustic response of the transmission.
