Efficiency of Planetary Gear Trains as Criterion for Optimal Solution Selection

Efficiency is one of the important criteria for the design and evaluation of the construction quality. Power losses in planetary transmissions consist of losses in the gear contact, losses in bearings, losses in sealings, losses due to oil viscosity etc.The calculation of the gear transmission efficiency is generally confined to losses depending on friction on tooth sides, i.e. on the calculation of contact power losses. Nevertheless, it is not suitable for using efficiency as only criterion for optimal solution choice, but as a one of the set of criteria. The objective of this paper, is the application of multicriteria optimization to the planetary gear trains with efficiency as one of the criteria. Apart the determination of the set of the Pareto optimal solutions, the weighted coefficient method for choosing an optimal solution from this set is included in order to prioritize particular criterion.
