Résumé

An original formulation for tooth friction power losses in internal gears including the influence of tooth profile modifications is presented. For unmodified gears, the results agree well with the classic formulae in the literature thus validating the proposed approach. The contributions of profile modifications on internal gear efficiency are compared to that on external gears and the formulation is extended to planetary gears. Finally, the role of profile relief on planetary gear efficiency is pointed out and commented upon.
