The influence of modification parameters and displacement of planetary gear wheels of planetary gearboxes on the service life of planetary gearboxes was considered. The calculation on the strength of planetary series gears in the software package KISSsoft at different displacements and different modifications of the original contours of the gears allowed GOST 13755-81 under the load corresponding to different modes of operation of the planetary series was carried out. The modification parameters and values of the initial loop displacement factor were found, in case of which the planetary series has the longest service life in each mode of operation. The results of gear strength calculations have been analyzed and the recommendations on the selection of modification and displacement parameters were developed.
