The invention discloses a propeller and a transmission device thereof, and belongs to the technical field of power transmission. The invention aims at solving the problems that in the prior art, whena propeller is installed, calibration needs to be conducted through special equipment to ensure concentricity, the requirement for the technical level of an operator is high due to the quite complex installation process, and the dismounting process is complex and time-consuming due to the complex connecting structure. End teeth and second screw holes are arranged on the end face of the propeller installation end, and the end teeth are distributed around the axial direction of the propeller in a central symmetry mode.
本发明公开了动力传输技术领域的一种螺旋桨及其传动装置,旨在解决现有技术中安装螺旋桨时需要通过专用设备进行校准以确保同心度,由于安装工艺十分复杂导致对操作人员的技术水平要求较高,以及连接结构复杂导致拆卸过程复杂耗时的技术问题。所述螺旋桨安装端的端面设有端齿和第二螺孔,所述端齿绕螺旋桨轴向呈中心对称分布。
