The invention discloses a tail drive assembly for an unmanned helicopter, and relates to the technical field of unmanned helicopters.The tail drive assembly comprises a tail drive control box, a tail motor is installed on the bottom face of the tail drive control box, a tail drive fixing seat is installed on the side face of the tail drive control box, and a steering engine is installed in the tail drive control box; an output shaft of the tail motor is coaxially and fixedly connected with a tail rotating shaft penetrating through the tail drive control box, the top end of the tail rotating shaft is fixedly provided with a propeller hub, the outer side of the upper end of the tail rotating shaft is slidably sleeved with a double-push crab claw assembly, an output shaft of the steering engine is provided with a steering engine arm, and the top end of the steering engine arm is rotationally connected with a connecting rod assembly; a double-push assembly is fixedly installed on the top face of the tail drive control box, and the end, away from the steering engine arm, of the connecting rod assembly is fixed to the double-push assembly. According to the invention, the pressure loss between the tail rotating shaft and the crab claw ring caused by one-way stress is obviously reduced, the service life of parts is prolonged, and the maintenance frequency and cost are reduced.

    本发明公开了一种无人直升机用尾驱总成,涉及无人直升机技术领域,包括尾驱控制箱,其中,所述尾驱控制箱的底面安装有尾电机,尾驱控制箱的侧面安装有尾驱固定座,所述尾驱控制箱的内部安装有舵机,所述尾电机的输出轴同轴固定连接有贯穿尾驱控制箱的尾转动轴,所述尾转动轴的顶端固定安装有桨毂,尾转动轴的上端外侧滑动套接有双推蟹爪组件,所述舵机的输出轴上安装有舵机臂,所述舵机臂的顶端转动连接有连杆组件,所述尾驱控制箱的顶面固定安装有双推组件,所述连杆组件远离舵机臂的一端与双推组件固定。本发明显著降低了因单向受力导致的尾转动轴与蟹爪环之间的压力损耗,延长了零部件的使用寿命,减少了维护频率和成本。
