REDUNDANT ELECTROMECHANICAL POWER MINI-DRIVE Russian patent published in 2021 - IPC H02K7/116 B64C13/50 B64D31/14 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft control systems. Redundant electromechanical power mini-drive consists of several actuating mechanisms, each of which comprises a frameless electric motor, a two-stage wave gear with rolling elements and an electromechanical clutch. Each actuator is supplemented with the second electric motor located in tandem with the first one on common shaft (5). Electromechanical coupling is made of two half-couplings. One half-coupling is input shaft (18). Second one is composite, consisting of intermediate link and output shaft (19). Inner cylindrical surface of intermediate link and outer surface of outlet shaft (19) are equipped with splines with balls (26) arranged in separator (27), so that intermediate link has axial movement relative to output shaft (19). Two eccentrics (20) with cylindrical protrusions at the ends are arranged on the output shaft, diametrically on the non-crossing axes to the longitudinal axis on the bearings, at the same time on the cylindrical projections on the bearings the levers of electromagnetic armatures (21) and disconnection (23) anchors are fixed.

EFFECT: higher drive reliability and longer service life.
