A Lumped Parameter Model to Analyse the Dynamic Load Sharing in Planetary Gears with Planet Errors
Résumé
A non-linear dynamic model of planetary gears is presented which accounts for planet position errors, time-varying non-linear mesh stiffness along with the interactions between deflections and instantaneous meshing conditions. The quasi-static load distributions agree well with the experimental results in the literature thus validating the contact simulation. Extensions towards high-speed behaviour are presented which show how dynamic effect may impact instantaneous load sharing amongst the planets.
