The invention relates to an ultrathin airfoil end joint assembly structure, which belongs to the field of ship device design and comprises a blade end and a rotating shaft end. The rotating shaft end comprises a rotating shaft and a rotating shaft connecting part arranged at the end of the rotating shaft, and the rotating shaft connecting part is of a cross-shaped structure and comprises a block-shaped structure and rotating shaft connecting plates arranged on the two parallel side faces of the block-shaped structure. Mounting grooves used for mounting the rotating shaft connecting parts are formed in the ends of the blades, and blade connecting plates capable of being connected with the rotating shaft connecting plates are arranged on the two opposite side walls of each mounting groove; during installation, the surfaces of the rotating shaft connecting plates are attached to the surfaces of the blade connecting plates, and the blocky structures abut against the position between the two blade connecting plates. The rotating shaft is connected with the end head through the fastening piece, the cross-shaped head is in plane connection with the end head groove, and the plane connection is a multi-directional contact surface, so that large torque and bending moment can be transmitted.
本发明涉及一种超薄翼型端部接头装配结构,属于船舶装置设计领域,其包括叶片端头和转轴端头;转轴端头包括转轴和设于转轴端部的转轴连接部,转轴连接部为十字型结构,其包括块状结构和设于块状结构两个相平行侧面的转轴连接板;叶片端头设有用于安装转轴连接部的安装槽,安装槽两个相对的侧壁设有可与转轴连接板连接的叶片连接板;安装时转轴连接板表面与叶片连接板表面贴合,块状结构抵接于两个叶片连接板之间。本发明通过紧固件将转轴与端头连接,“十字”头与端头开槽为平面连接,而且为多向接触面,可专递较大扭矩、弯矩。
