The invention belongs to the technical field of aviation electric actuator design, and particularly relates to an aviation electric actuator with a manual function. Comprising a motor (1), a speed reducer (2), an overrun clutch (4), an electric connector (8) and a manual working mode switching assembly. In a normal electric working mode, the motor drives the speed reducer to rotate, and torque is output through an output shaft (4a) of the overrun clutch (4); when a motor breaks down or needs to be switched to a manual working mode, the manual working mode switching assembly is connected with an output shaft (4a) of the overrun clutch (4), and the output shaft (4a) of the overrun clutch (4) is separated from an outer ring (4d) of the overrun clutch (4) by operating the manual working mode switching assembly. And the manual working mode switching assembly drives an output shaft (4a) of the overrun clutch (4) to output torque. The single-point failure fault of the motor is prevented, the task reliability of the electric actuator is greatly improved, and the device is simple and reliable in structure, flexible and convenient to operate and capable of being widely applied to aviation products needing a manual function.
本发明属于航空电作动器设计技术领域,具体涉及一种具有手动功能的航空电作动器。包括电动机(1)、减速器(2)、超越离合器(4)、电连接器(8)、手动工作模式切换组件;在正常电动工作模式下,电动机驱动所述减速器旋转,通过所述超越离合器(4)的输出轴(4a)输出扭矩;当电动机故障或者需要切换到手动工作模式时,所述手动工作模式切换组件与所述超越离合器(4)的输出轴(4a)相连,通过操作所述手动工作模式切换组件使所述超越离合器(4)的输出轴(4a)与所述超越离合器(4)的外环(4d)脱开,进而由所述手动工作模式切换组件带动所述超越离合器(4)的输出轴(4a)输出扭矩。防止电动机单点失效故障,大大提高了电作动器的任务可靠性,本发明装置结构简单可靠,操作灵活方便,可广泛运用在需手动功能的航空产品中。
