The invention discloses a rotor head structure of a single-rotor unmanned helicopter without ailerons. The invention belongs to the technical field of unmanned aerial vehicles. The rotor head structure comprises a rotor wing seat, a rotor wing paddle clamp assembly and a flapping damper, the rotor wing seat is positioned below the rotor wing paddle clamp assembly, the flapping damper is positionedin the middle of the rotor seat, three evenly-distributed transverse holes are formed in the front end face of the rotor wing propeller clamp assembly, a pull button sheet structure is arranged in the middle of each of the three transverse holes, the rotor wing propeller clamp assembly comprises two propeller clamps, a rotor cross shaft is arranged between the two propeller clamps, bearings are arranged on the left and right sides of the rotor cross shaft, pull button sheets are fixedly connected to the left side and the right side of the rotor cross shaft, a bearing spacer is provided on theinner side wall of the bearing, and a gland is provided above the horizontal axis of the rotor. According to the rotor wing, the structural form is simplified, the number of parts is reduced, and thestructural mass is reduced, so that the mutual operation of the structural parts is flexible and stable, and the rigidity and the weight of the parts are in a good state besides the function requiredby flight is met.

    本发明公开了一种单旋翼无副翼无人直升机旋翼头结构,属于无人机技术领域,包括旋翼座、旋翼桨夹组件和挥舞阻尼,旋翼座位于旋翼桨夹组件的下方,挥舞阻尼位于旋翼座的中部,旋翼桨夹组件的前端面设置有三个均匀分布的横孔,三个横孔的中部均设置有拉钮片结构,旋翼桨夹组件包括两个桨夹,两个桨夹之间设置有旋翼横轴,旋翼横轴的左右两侧均设置有轴承,旋翼横轴的左右两侧均固定连接有拉钮片,轴承的内侧壁设置有轴承隔套,旋翼横轴的上方设置有压盖,该旋翼结构形式简化,减少零件数量,降低结构质量,使得结构零件相互间运转灵活平稳,在满足飞行所需的功能外,其零件的刚性及重量均处于一个良好的状态。
