ELECTROMECHANICAL DRIVE UNIT FOR AIRCRAFT MAIN LANDING GEAR WHEEL DISC BRAKE Russian patent published in 2014 - IPC B64C25/44 F16D55/36 F16D65/18 

FIELD: transport.

SUBSTANCE: invention relates to air transport, specifically to electromechanical drives of aircraft brakes. The unit consists of two modules installed on flange fixed on wheel axle. Each of the modules has body, thrust plunger, screw mechanism located in the body, electric motor connected with screw drive reducing gear. In the inside axial cavity of the screw, electric motor with rotor is installed. On one of electric motor shaft ends, wave former of the first stage of double-stage harmonic reducing gear and wave former incorporating separator of the first stage of harmonic reducing gear are placed. The separator is connected with electric motor body and has the first intermediate rotation bodies interacting with separator incorporating rigid wheel, with inner waved surface. Rigid wheel of the second stage has shaft installed coaxially with electric motor rotor which shaft has wave former of the second stage of harmonic reducing gear, with separator connected with electric motor body which separator has the second intermediate rotation bodies. Part of screw surface incorporating harmonic reducing gear second stage wave former has inside waved surface.

EFFECT: decreased unit dimensions, higher unit efficiency and reliability.
