Integration of FEM planet carriers made easy


Presented by FE expert Georg Hammerl, FVA GmbH

The influence of the planet carrier on the gearing and the bearings in a planetary stage is of essential importance. Modeling with rudimentary bodies, e.g. shafts and hollow shafts, neglects several deformation possibilities in which material reserves cannot be exhausted in the design. The use of an FEM model of the planet carrier, on the other hand, allows a much more realistic description. This demonstration provides an overview of the FE feature.
