The paper is devoted to the analysis of the main factor affecting the resource of a pinion gear with a plastic satellite, that is the dependence of the resource on the output shaft torque according to the criteria of contact endurance of cycloidal gearing and the performance of the satellite bearings for the planetary pinion gear, assembled on the basis of the RK-3 Department in Bauman Moscow State Technical University. The criteria for calculating the resource was established: when the torque on the output shaft is varied subject to the T≤63∙〖10〗^3 N∙mm condition, the calculation should be carried out according to the criterion of contact endurance, with a further increase in this parameter, the resource of the satellite bearing will be the limiting factor.
