The invention belongs to the field of tilting mechanism design of tilting rotor aircrafts, and particularly relates to a multi-redundancy tilting rotor head space motion mechanism which comprises a rotor head assembly, a driving rocker arm assembly, a rocker arm assembly, a connecting rod assembly, a crank assembly, a main driving actuator, a fixed support and other components. A support is arranged on the rotor head assembly and used for controlling the moving posture of the rotor head assembly. Spatial motion of the rotor head assembly is achieved through rotation of a four-connecting-rod mechanism composed of the connecting rod assembly, the rocker arm assembly and the like around the fixed support. A piston rod and an outer cylinder structure are arranged at one end of the driving rocker arm assembly and serve as backups of the driving assembly, and when a main driving actuator fails, the actuator can drive the four-connecting-rod mechanism to continue to move, so that tilting movement of the rotor head is achieved.

    本申请属于倾转旋翼飞机倾转机构设计领域,特别涉及一种多余度倾转旋翼头空间运动机构,包括:旋翼头组件、驱动摇臂组件、摇臂组件、连杆组件、曲柄组件、主驱动作动器、固定支座等构件。旋翼头组件上布置了支座,用于控制其运动姿态。旋翼头组件的空间运动通过连杆组件、摇臂组件等组成的四连杆机构绕固定支座的旋转实现。驱动摇臂组件一端设置了活塞杆和外筒结构,作为驱动组件的备份,当主驱动作动器失效时,该作动器可以驱动四连杆机构继续运动,实现旋翼头的倾转运动。
