The invention belongs to the technical field of aircraft blades, and discloses a self-adaptive variable-pitch blade with a limiting function, which comprises a base cylinder, the left end and the right end of the base cylinder fixedly communicate with two symmetrically distributed mounting cylinders, one end, far away from the base cylinder, of each mounting cylinder is connected with a propeller hub end cover, and the propeller hub end covers are coaxially and rotatably connected with blades; the paddles are coaxially and fixedly connected with rotating bearings, the ends, away from the paddles, of the rotating bearings are coaxially and fixedly connected with paddle handles, the ends, away from the paddles, of the paddle handles are coaxially connected with torsion springs, the other ends of the torsion springs are connected with torque adjusting rings, and the torque adjusting rings are rotationally connected with the mounting cylinder. Synchronous rocker arms are coaxially and fixedly connected to the sides, close to the base cylinder, of the paddle handles, synchronous swing rods are eccentrically connected to the two synchronous rocker arms, the two synchronous swing rods reversely rotate around the mounting cylinder, a synchronous sliding sleeve is connected to the interior of the base cylinder in an up-down sliding mode, synchronous rails are formed in the left side and the right side of the synchronous sliding sleeve, and the synchronous swing rods are arranged in the synchronous rails; and the practicability is high.
本发明属于涉及飞机桨叶技术领域,且公开了一种具备限位功能的自适应变距桨叶,包括底座筒,底座筒左右两端均固定连通有两个对称分布的安装筒,安装筒远离底座筒一端均连接有桨毂端盖,桨毂端盖均同轴转动连接有桨叶,桨叶均同轴固定连接有转动轴承,转动轴承远离桨叶一端同轴固定连接有桨把,桨把远离桨叶一端均同轴连接有扭力弹簧,扭力弹簧另一端均连接有扭矩调节环,扭矩调节环和安装筒转动连接,桨把靠近底座筒一侧均同轴固定连接有同步摇臂,两个同步摇臂均偏心连接有同步摆杆,两个同步摆杆绕安装筒反向转动,底座筒内部上下滑动连接有同步滑套,同步滑套左右两侧均开设有同步轨道,同步摆杆置于同步轨道内部;且实用性强。
