A support body is a rotary body, two grooves and a mounting hole are formed in the end, close to a carbon tube, of a foam core, and the support body is inserted into an inner cavity of the carbon tube and the mounting hole of the foam core. Meanwhile, a center balance weight hole and a plurality of edge balance weight holes are formed in the support body in the axial direction of the support body, the center balance weight hole is located in the center of the support body, the edge balance weight holes are distributed around the center balance weight hole in a circumferential array mode, and the same ends of the center balance weight hole and the edge balance weight holes are open ends; and the other same end is a closed end. The invention discloses a propeller blade counterweight support, which can adjust the large and small axis torque of a blade to ensure the balance of a propeller, and can avoid the problem of pneumatic imbalance, thereby improving the safety and reliability.

    本发明公开了一种螺旋桨桨叶配重支座,支座本体为回转体,且泡沫芯靠近碳管的一端开设有两个凹槽以及开设有一个安装孔,支座本体分别插接在碳管的内腔和泡沫芯的安装孔中,同时支座本体上沿其轴向分别开设有一个中心配重孔和多个边缘配重孔,且中心配重孔位于支座本体的中心,多个边缘配重孔围绕中心配重孔呈圆周阵列分布,并且中心配重孔和多个边缘配重孔的一同端均为开口端,另一同端均为封闭端。本发明公开了一种螺旋桨桨叶配重支座,能够调整桨叶的大、小轴线力矩,以保证螺旋桨平衡,同时可以避免气动不平衡的问题,从而提高了安全性和可靠性。
