A propeller variable pitch system relates to the field of propellers and comprises a spindle, a first swash plate assembly, a second swash plate assembly and a synchronization assembly, one end of the spindle is connected with a first propeller component, the other end of the spindle is connected with a second propeller component, and the central axis of the spindle coincides with the rotating axis of the first propeller component; the first swash plate assembly is arranged on the main shaft and can move in the axial direction of the main shaft so as to adjust the blade angle of the first propeller component. The second swash plate assembly is arranged on the main shaft and can move in the axial direction of the main shaft so as to adjust the blade angle of the second propeller component. The synchronizing assembly is connected with the first swash plate assembly and the second swash plate assembly. The two propeller components can be controlled at the same time to conduct synchronous pitch changing, the pitch changing consistency is guaranteed, the problem that the pitch changing of the two propeller components is not consistent is solved to a great extent, the pitch changing efficiency is improved, the occupied space is reduced, and the weight is reduced.
一种螺旋桨变距系统,涉及螺旋桨领域,包括:主轴、第一倾斜盘组件、第二倾斜盘组件和同步组件,主轴一端同第一螺旋桨构件连接,另一端同第二螺旋桨构件连接,且主轴的中心轴线同第一螺旋桨构件的转动轴心线重合;第一倾斜盘组件设于主轴,并可沿主轴的轴向运动,以调整第一螺旋桨构件的桨叶角;第二倾斜盘组件设于主轴,并可沿主轴的轴向运动,以调整第二螺旋桨构件的桨叶角;同步组件连接第一倾斜盘组件和第二倾斜盘组件。其能够同时控制两个螺旋桨构件进行同步变距,并且保证变距的一致性,极大程度的避免了两个螺旋桨构件变距不一致的问题,提高变距效率,减小占用空间,降低重量。
