The invention discloses a tilting rotor claw disc type constant-speed universal hinge propeller hub, the propeller hub uses a universal assembly composed of a rocker arm and a gear to realize the function of a traditional universal hinge and can meet the requirement of a small-sized tilting rotor aircraft for all-dimensional constant-speed transmission, and the universal assembly can enable the whole propeller hub structure to be more compact and more compact. And the number of parts is reduced. According to the variable-pitch assembly of the propeller hub, the elastic bearing is used for replacing a metal bearing to achieve the variable-pitch function, the service life of the propeller hub is prolonged, meanwhile, the weight is reduced, and the problem of dynamic instability is solved. The tilting rotorcraft has innovative significance on development of the tilting rotorcraft in the future.

    本发明公开了一种倾转旋翼爪盘式等速万向铰桨毂,该桨毂使用由摇臂和齿轮组成的万向组件实现传统万向铰的功能,并且能满足小型倾转旋翼机对于全方位等速传动的要求,该万向组件可以使整个桨毂结构更加紧凑,并且减少了零件数量。该桨毂的变距组件利用弹性轴承代替金属轴承实现变距的功能,做到了提高桨毂寿命的同时,重量也在减轻,缓解了动力学不稳定问题。对未来倾转旋翼机的发展具有创新意义。
