ELECTROMECHANICAL LINEAR DRIVE Russian patent published in 2014 - IPC F16H25/22 B64C13/28 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering and can be used in aircraft airfoil drives, particularly that of leading edge flaps, tail flaps, ailerons. Electromechanical linear drive consists of body, located inside it electric motor with rotor connected with screw of screw or ball-screw mechanism via harmonic reducing gear. Inside the body pusher is installed with possibility of translational motion, as well as stopper is mounted. The mentioned rotor is connected with its angular position sensor. Harmonic reducing gear is of single-stage type and has wave former placed on its shaft which wave former consists of two cams with oppositely directed eccentricities and with bearings and building rings installed on them. In the separator which is connected with body and incorporates wave former, rotation bodies interacting with building rings are placed. The rigid wheel with inner waved surface incorporates the separator and has shaft installed coaxially with electric motor rotor which shaft is connected with screw directly or via one or more intermediate stages.

EFFECT: decreased dimensions and increased efficiency of drive.
