| description | The invention provides a rotor shaft assembly, an aircraft transmission system main speed reducer provided with the rotor shaft assembly and an aircraft provided with the aircraft transmission systemmain speed reducer. The rotor shaft assembly comprises a shaft body, a planetary frame arranged at one end of the shaft body, and at least one deformation compensating part, wherein the deformation compensating part is formed on a position, between the two ends of the shaft body, of the shaft body. The rotor shaft assembly reduces load, borne in a working process, of the planetary frame, reduces influences on the planetary frame, and improves stability of the planetary frame; and meanwhile, the deformation compensating part enables the planetary frame to generate micro displacement in a radialdirection in a working process, so that a contact state between each planetary gear and a solar wheel trends to be consistent, and therefore, uniform-load performances of the planetary gears are improved.
