| Abstract | The paper presents an epicyclic gear train dynamic mathematical model including mesh efficiency, bearings/seals losses and inertial effects. The mathematical model treats separately the mesh between sun and planets gears and the mesh between planets and ring gears. Two different ordinary efficiency values for each gear pair can be specified for forward and reverse power transmission through it. The mesh efficiency is inserted into the dynamic model through a change in the direction of the mean reaction force between tooth surfaces [4]. The extension of the equations valid for ordinary gearing to elementary gear train with epicyclic arrangement is made by using the kinematic inversion [2]. A formula for selecting the correct efficiency value, to be used in the model, depending on the direction of power flows along the epicyclic gear train is presented. Finally, in order to check the validity of the dynamic model proposed, a steady-state working condition is analysed in detail and the mesh efficiency resulting from a numerical simulation of the model is compared with analytical formulas [7]. |
