The invention discloses an electric driving mechanism suitable for a wing folding
system. The electric driving mechanism comprises a shell, a worm and gear is used for transmission, and the self-locking performance of the worm and gear can be utilized to keep the stability of transmission all the time; an NGWN planetary
reducer is adopted as an output mechanism, so that the large
transmission ratio of the whole transmission chain is achieved, double-
rocker arm output is achieved, the stability of rotary output is improved, and an angle detection device is beneficial to improving the control precision; an outer hexagonal interface is designed on the worm, so that manual input can be realized; and compared with a hydraulic driving structure, the electric driving mechanism has the advantagesthat a motor and a
gear transmission system can be combined into a unit, so that parts such as hydraulic oil, an
oil tank, an oil conveying pipeline and a control valve are reduced, the weight of thewhole
airplane can be reduced, corresponding circuits, chips, sensors and the like can be matched for control, and the stability of the wing folding process is guaranteed; and the
system is high in integration degree, simple in structure, convenient to install and beneficial to maintenance and overall replacement.
