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.
本发明公开了适用于机翼折叠系统的电动驱动机构,包括外壳,使用蜗轮蜗杆传动,可以利用蜗轮蜗杆的自锁性能,时时保持传动的稳定性;采用NGWN行星减速器作为输出机构,有利于实现整个传动链较大的传动比,双摇臂输出,提高了旋转输出的稳定性,角度检测装置有利于提高控制精度;蜗杆上设计有外六方接口,可实现手动输入,相比于液压驱动结构采用本发明可以将电机和齿轮传动系统组成为一个单元,减少了液压油、油箱、输油管路、控制阀等部件,有利于减轻飞机整机重量,可以配套相应的电路、芯片、传感器等进行控制,保证机翼折叠过程平稳,本发明系统集成度高、结构简单、安装方便,有利于维护及整体更换。
