| This dissertation deals with systematic methods of analysis of planetary gear trains.;After a review of previous contributions on the estimation of efficiency in simple gear trains, the author introduces new methodologies for power-flow and mechanical efficiency analysis of epicyclic spur-gear trains.;The systematic nature of the methodologies, based on the dual correspondence between the kinematic structure of gear drives and labeled graphs, allows a ready coding of the suggested algorithms.;Moreover, as far as the kinematic analysis of bevel-gear trains with gyroscopic complexity, the algorithm of Freudenstein, Longman and Chen has been reformulated in a parametric fashion to ease its computer implementation.;For each algorithm developed numerical examples have been always carried out and the results compared with those obtained by different authors. |
