The invention discloses an unmanned helicopter propeller hub and an unmanned helicopter. The propeller hub comprises an inner main shaft, an outer main shaft, an upper T-shaped split propeller hub, alower T-shaped split propeller hub, upper flapping rubber and a lower flapping rubber, wherein the upper T-shaped split propeller hub and the upper flapping rubber are arranged on the inner main shaft, the lower T-shaped split propeller hub and the lower flapping rubber are arranged on the outer main shaft, the inner main shaft and the outer main shaft are respectively provided with two opposite boss mounting surfaces, the upper T-shaped split propeller hub is connected with a boss mounting surface of the inner main shaft through an upper propeller hub screw, and the lower T-shaped split propeller hub is connected with a boss mounting surface of the outer main shaft through a lower propeller hub screw, the upper T-shaped split propeller hub is connected to form an integral upper propellerhub, the lower T-shaped split propeller hub is connected to form an integral lower propeller hub, and the propeller hubs integrally swing around the propeller hub screw. The unmanned helicopter propeller hub is advantaged in that maintenance cost of the propeller hub system can be reduced.

    本发明公开了一种无人直升机桨毂及无人直升机,该桨毂包括内主轴、外主轴、上T形分体桨毂、下T形分体桨毂、上挥舞橡胶和下挥舞橡胶。所述上T形分体桨毂与上挥舞橡胶配置于所述内主轴上,所述下T形分体桨毂与下挥舞橡胶配置于所述外主轴上;所述内外主轴分别设置有面对面的两个凸台安装面,所述上T形分体桨毂通过上桨毂螺杆连接到所述内主轴凸台安装面,所述下T形分体桨毂通过下桨毂螺杆连接到所述外主轴凸台安装面;所述上T形分体桨毂连接形成整体的上桨毂,所述下T形分体桨毂连接形成整体的下桨毂,桨毂整体围绕桨毂螺杆做挥舞运动。本发明无人直升机桨毂可以降低桨毂系统维护成本。
