The invention discloses a timely speed regulation internal gear planetary gear train mechanism of a multi-rotor unmanned aerial vehicle, whichbelongs to the technical field of unmanned aerial vehicles. The timely speed regulation internal gear planetary gear train mechanism of the multi-rotor unmanned aerial vehiclecomprises rotors, a planetary gear train, an engine, a speed regulation motor and aworm, wherein an output shaft of the speed regulation motor is in transmission connection with one end of the worm, and the worm is meshed with an inner gear ring of the planetary gear train; an output shaft of the engine is in one-way or fixed connection with a center wheel of the planetary gear transmission mechanism, and the rotors are in one-way or fixed connection with the middle of a tie bar of the planetary gear train. The problem that the rotating speeds of all engines of an oil-driven multi-rotor unmanned aerial vehicle are difficult to keep consistent is solved.
