Planetary gear stages are commonly used in many different fields of application, including wind turbine and automotive gearboxes. This paper discusses the potential for increased root load carrying capacity at the planet gear of a planetary gear application. The approach considers local material characteristics such as hardness, fatigue strength, and mean stress sensitivity, as well as residual stresses and different stress rations that result from the mesh with the sun and ring gear. It offers a detailed tooth contact analysis based on the Finite Element Method. The result of this work allows for the possibility of changes in the gear design.
