A coaxial concentric cylinder with the same inner diameter is installed on one side of the vertical face of a sun gear of a planetary gear paddle fan combined engine device, a solid shaft is arrangedin the center of the cylinder, a plurality of forward-rotation turbofan blades are uniformly arranged between the cylinder and the solid shaft, a coaxial and concentric horn-shaped cylinder is mountedon one side of the vertical surface of an internal meshing gear wheel, a hollow shaft is arranged in the center of the cylinder, a plurality of reverse-rotation turbofan blades are uniformly arrangedbetween the cylinder and the hollow shaft, forward-rotation blades are evenly arranged outside the sun gear cylinder, reverse-rotation blades are evenly arranged outside the horn-shaped cylinder of the internal meshing gear, motors are fixed to the proper position of a gear support and are coaxially and concentrically connected with the planetary gear, the sun gear center solid shaft penetrates through the internal meshing gear center hollow shaft and extends to the other end, the diameters of the two shafts are different, and a bearing is arranged between the two shafts. The beneficial effects of the device are as follows: the multiple motors drive to form multiplied driving resultant force, so the requirements for high power and high torque are fully met; the motors work at a high speedin groups in turn, so complete parking caused by damage of a certain motor can be prevented; and the combination mode of the two sets of blades and the two sets of turbofans is reasonable, so relative rotation is achieved, reverse torque is counteracted, influences on sailing are avoided, and the mechanical efficiency can be very high.
行星齿轮桨扇组合发动机装置的太阳齿轮立面一侧安装同轴同心同内径的圆形筒柱,筒柱中心有实心轴,筒柱与实心轴之间均匀布置数个正旋涡扇叶片,内啮齿轮立面一侧安装同轴同心的喇叭形筒柱,筒柱中心有空心轴,筒柱与空心轴之间均匀布置数个反旋涡扇叶片,太阳齿轮筒柱外均匀布置正旋桨叶,内啮齿轮喇叭形筒柱外均匀布置反旋桨叶,电机固定在齿轮支架适当的位置与行星齿轮同轴同心连接,太阳齿轮中心实心轴穿过内啮齿轮中心空心轴并延伸到另一端,两轴直径有差异且之间有轴承。本发明有益效果在于:多个电动机驱动形成倍增驱动合力,充分满足大功率、高扭矩要求,电机分组轮流高速工作,又可以防止某一电机损坏造成完全停车,两组桨叶和两组涡扇结合方式合理,均相对旋转,抵消反向力矩避免对航行影响,其机械效率可以很高。
