REDUNDANT SELF-LOCKING DRIVE Russian patent published in 2018 - IPC F16H3/72 F16H48/00 

FIELD: aviation; astronautics.

SUBSTANCE: invention relates to mechanisms and instruments with multiple redundancy by operating from two motors to sum the angular movements and can be used in aircrafts and spacecrafts. Redundant self-locking drive contains two motors 1 and 2 with parallel shaft axes and a differential with cylindrical center wheels 3 and 4 of the external and internal engagement kinematically associated with one of the shafts of engines 1 and 2 by means of cylindrical wheels 7 and 8. Width of each of wheels 3 and 4 of the differential is selected from the condition of their simultaneous interaction with planetary gears 5 and cylindrical wheels 7 and 8 of the engine. Between engines 1 and 2 and wheels 7 and 8 of different diameters, unidirectional movement mechanisms 9 and 10 are installed.

EFFECT: invention is aimed to increase the reliability of the drive operation in the event of failure of any of the engines for any reason.
