The invention discloses an electric ship outboard motor driving structure which comprises a shell and a driving assembly. A first motor shaft gear and a second motor shaft gear are in key connection with a first motor shaft and a second motor shaft respectively; a transmission shaft gear is simultaneously meshed with the first motor shaft gear and the second motor shaft gear; a rotating shaft is horizontally and rotationally arranged on the inner wall of the lower shell, and the first paddle is arranged on the first paddle mounting pipe; a third bevel gear is arranged on the rotating shaft, and the third bevel gear is meshed with the first bevel gear; a fourth bevel gear is rotationally connected with the rotating shaft, and the fourth bevel gear is engaged with the first bevel gear; a connector is connected with the fourth bevel gear; and a second paddle is arranged on the second paddle mounting pipe. According to the invention, by arranging the double motors, the overall working efficiency is improved, the size is reduced, and the power density is improved; the arrangement structure accords with the fluid mechanics principle, and the water facing area is reduced compared with the single equal motor power; therefore, the water facing area of the whole machine is reduced, the water facing face better meets the hydromechanics requirement, and the sailing efficiency is improved.

    一种电动船外挂机驱动结构,包括壳体和驱动组件;第一电机轴齿轮和第二电机轴齿轮分别与第一电机轴以及第二电机轴键连接;传动轴齿轮同时与第一电机轴齿轮以及第二电机轴齿轮啮合;转动轴水平且转动设置在下壳体内壁上,第一桨叶设置在第一桨叶安装管上;第三斜齿轮设置在转动轴上,第三斜齿轮与第一斜齿轮啮合;第四斜齿轮与转动轴转动连接,第四斜齿轮与第一斜齿轮啮合;连接体与第四斜齿轮连接;第二桨叶设置在第二桨叶安装管上。本发明中,通过设置双电机使整体工作效率提高,同时缩小体积,提升功率密度,且排列结构符合流体力学原理,比单一同等电机功率迎水面积减少,使整机迎水面积减小,迎水面更符合流体力学要求,提高了淌水效率。
