[en] The presented work concerns a very important part of the planetary gear train, namely, a design of the planet carrier. An application of heavy-duty commercial gearboxes is selected because large torque levels dominate in this application and then the design of the carrier is crucial. One of the most important parameters of the plant carrier is its torsional stiffness, which has a direct influence on stress level gears. The low stiffness leads to uneven contact between the gears during loading which reduces pitting resistance of the gears. The next important parameter is the stress level in the planet carrier, because of varying torque the planet carrier is exposed to fatigue failure. These two parameters are taken in a design process as the main factors.
A topology optimization method was used to find a direction to design the torsional stiff carrier also taking into account a size limit of the carrier.
The project is done with the purpose of showing that the usage of the optimization tool helps significantly to design a new part, which excels a standard part in terms of structural performance.
