REDUNDANT ELECTROMECHANICAL DRIVE Russian patent published in 2020 - IPC B64C25/18 

FIELD: machine building; aviation.

SUBSTANCE: invention relates to redundant electromechanical drives, actuators of which are protected against jamming and intended for actuation of aerodynamic surfaces or chassis of aircraft. Redundant electromechanical drive comprises main and standby control channels, each of which comprises uncased dispenser motor with electromagnetic brake and mechanical transmission, input shaft of which is connected to rotor shaft of electric motor, and output shaft - to one of input links of differential wave gear including wave former, flexible and rigid wheels. Main and backup channels are identical, with redundant motors and electromagnetic brakes. Wave transmissions with rolling elements are used as differential wave transmission and mechanical transmissions, in which flexible wheels are separators with rolling elements. Wave-formers are made of bearings fitted on axle with eccentrics. At wave transmissions output links are rigid wheels on which eccentrics with bearings are installed. Differential wave transfer separator is installed with possibility of rotation relative to housing.

EFFECT: increased service life of drive.
