The invention belongs to a propeller hub structure, and provides a universal hinge propeller hub of a tilt-rotor aircraft and the tilt-rotor aircraft to solve the technical problems that due to the propeller hub structure, the service life of the aircraft is short, the reliability is poor, the maximum take-off weight is limited, and the aircraft with the larger weight class is difficult to develop. The ball cage universal hinge and the propeller hub bearing are used for being installed on a rotor wing shaft of the aircraft. The propeller hub bearing is used for being installed on a rotor wing shaft and is coaxially and detachably connected with the ball cage universal hinge. The variable-pitch hinge comprises a variable-pitch hinge body and a variable-pitch rocker arm connected to the side wall of the variable-pitch hinge body, one end of the variable-pitch hinge body is installed on the ball cage universal hinge, and the other end of the variable-pitch hinge body is used for being connected with the paddle. One end of the variable-pitch rocker arm is mounted on the variable-pitch hinge, and the other end is connected with a control mechanism of the aircraft. The propeller hub is compact in structure, clear in force transmission route, light in weight and capable of meeting the requirements of small and medium-sized tilt-rotor aircrafts.

    本申请属于一种桨毂结构,针对由于桨毂构型造成飞行器使用寿命低,可靠性差,最大起飞重量受限,以及难以研制更大重量级别的飞行器的技术问题,提供一种倾转旋翼飞行器的万向铰桨毂、倾转旋翼飞行器,包括变距铰,以及用于安装在飞行器的旋翼轴上的球笼万向铰和桨毂轴承。桨毂轴承用于安装在旋翼轴上,与球笼万向铰同轴可拆卸连接。变距铰包括变距铰主体和连接在变距铰主体侧壁上的变距摇臂,变距铰主体一端安装在球笼万向铰上,另一端用于连接桨叶。变距摇臂一端安装在变距铰上,另一端用于连接飞行器的操纵机构。本申请的桨毂结构紧凑,传力路线清晰,重量较轻,能够满足中小型倾转旋翼飞行器需求。
