Vibroexcitation in the meshing of imprecise deformable teeth in a spur gear: A review

A physicomathematical model of the vibroexcitation in the meshing of imprec ise deformable spur-gear teeth is proposed. The gearing is regarded as a pa rametric nonlinear system, with unilateral elastic connections that separat e under certain conditions, The structure of the system varies over time, a ccording to the dynamic state of the system. Analytical expressions for the exciting forces are obtained, along with the equations of motion, the rele vant algorithm, information on the corresponding software, and computationa l and experimental data.
