The invention discloses an automatic inclinator with a novel structure, which is designed to meet the variable pitch requirement of a certain rotor aircraft, the automatic inclinator comprises a sliding sleeve, a rotating ring, a non-rotating ring, a bearing, an anti-torsion arm and other structural members, and has the characteristics of simple structure, reliable function, low production cost and the like. The sliding sleeve is mounted on a rotor shaft, and the internal polygonal structure can realize the movement of the automatic inclinator along the rotor shaft and can also realize synchronous belt rotation; the inner cavity can be used for storing lubricating grease to guarantee lubrication and reducing friction resistance; the guide design of the upper and lower ports can prevent the risk of movement clamping stagnation. The rotating ring is fixed to the sliding sleeve, and synchronous rotation of a propeller hub and a rotor wing shaft is achieved. Due to the design of the symmetrical double anti-torsion arms, the rotating motion of the non-rotating ring can be restrained, and the coordination of the up-down motion of the automatic inclinator can be guaranteed.

    本发明公开一种新结构自动倾斜器,该自动倾斜器为适应某旋翼飞行器变距需求而设计,由滑动套,旋转环、不旋转环、轴承、防扭臂等结构件组成,具有结构简单、功能可靠、生产成本低等特点。滑动套安装于旋翼轴上,内部多边形结构即可实现自动倾斜器沿旋翼轴的运动,又可以实现同步带转;内部空腔设计即可用于存储润滑油脂以保证润滑,又可减小摩擦阻力;上下端口的导向设计可防止运动卡滞风险。旋转环固定于滑动套上,实现桨毂和旋翼轴的同步转动。对称的双防扭臂设计即可约束不旋转环的旋转运动,又可保证自动自动倾斜器上下运动的协调性。
