MULTI-MOTOR ELECTRIC DRIVE FOR TURNING NOSE LANDING GEAR AND OPERATION METHOD THEREOF Russian patent published in 2016 - IPC B64C25/50 

FIELD: aviation.

SUBSTANCE: invention relates to landing gear design. Multimotor swing drive of nose undercarriage support comprises a fixed leg part and a moving part, the body attached to the fixed leg, and several electric drives with reduction gears and output shafts. Multimotor drive also comprises control units for servo drive motors, main control box (MCB) for servo drive motors connected by means of interface bus with the angular position sensor of the moving part of nose support with control units for servo drive motors and aircraft control system. Every servo drive motor of tracking electric drive is brushless, DC, energized by permanent magnets. Reduction gear of each servo drive is a harmonic drive with solids of revolution. Fitted on output shafts of reduction gears engagement means are cylindrical cams with line of symmetry, with rolling bearings interacting with teeth formed by cycloidal surface.

EFFECT: simplified design, higher reliability of multimotor swing drive of aircraft nose undercarriage support.
