The subject of the dissertation is an approach to describe gearboxes as thermal networks, which are combined with calculation models for the power losses of gearbox components like gears, bearings, sealings and planet carriers. The calculation model captures internal heat sources and flows as well as heat dissipation to the environment and provides thus steady state and transient efficiency behavior and individual component temperatures. Furthermore, a comparison to measurement results, gained from gear test rigs, and two application examples are given.
