Epicyclic gear transmissions are widely used in various industrial applications including robotic arms, hybrid vehicle power transmissions and turbine generators. Analysing and enhancing the operational efficiency of gear transmissions are important to design optimisation and control.
A complete framework based on constraint analysis and virtual power was developed for the analysis of epicyclic gear systems. Power flow diagrams were constructed to obtain possible power flow patterns and to verify the balance of normal/virtual power flows within the system, based upon which the theoretical efficiency formulae were derived for the full working range. The predictions were experimentally verified with a prototype.
