Input data, such as the speed of rotation of the input shaft of the gearbox, for the multi-criteria analysis of the planetary multiplier of the wind turbine were obtained from the results of computer simulation of the air flow. The fundamentals of the torque method were used to study planetary compound gears (PСG), called a multiplier. The variants of kinematic schemes of composite planetary transmission are analyzed in order to determine the most optimal distribution of the energy flow. The torque method allows not only kinematic analysis (determining the ratio of speeds), but also power analysis (determining the direction and magnitude of internal power flows), as well as determining efficiency. Relatively simple formulas for calculating the ratio of speeds and efficiency made it possible to carry out multi-purpose optimization of the parameters of the considered PСG. As a result of the analysis, the most optimal scheme of a composite planetary gearbox was determined, taking into account the kinematics of the airflow on the wind turbine wheel.enArticle
