High efficiency by maximum usage of available space, high gear ratios, best possible efficiencies and a wide range of applications due to the possibility of switching operations, superposition - and summation gearboxes are known properties of planetary gearboxes.
The optimization and effective utilization of these gearbox designs requires a detailed consideration of the loads on the gears in the gearbox. Therefore, standardized calculation methods, such as ISO 6336, DIN 3990 or AGMA 2001 can be used. To benefit from the full potential of the teeth, while the safety of the teeth can be assured at all times, advanced analysis of load distribution will be necessary.
Because of the need of the universal use of these calculation standards these methods use approximations that cannot cover the special characteristics of planetary gearboxes and therefore cannot be used to optimize the gears to their full potential. For this reason, computer aided calculation method have been developed for planetary gearboxes with spur and helical gears that consider the most important influences on the load distribution like housing deformation, bearing deformation, deformation of the planet carrier, deformation of the wheel bodies and the deformation of the teeth themselves. Using this information, a detailed load distribution is possible to reach the maximum capability of the gears.
