The invention aims to provide a ship underwater sectional type auxiliary propulsion rotor which comprises an inner tower, a first section rotor, a second section rotor, a first driving motor and a second driving motor, the inner tower comprises an upper inner tower and a lower inner tower, the upper inner tower is fixed on a ship, the lower inner tower and the upper inner tower are connected together through a coupler, the first section rotor is located outside the upper inner tower, the second section rotor is located outside the lower inner tower, the first section rotor and the second section rotor are connected with respective connecting rods through connecting flanges respectively, the respective connecting rods are connected with the upper inner tower and the lower inner tower through inner tower bearings respectively, the first driving motor is located in the cabin and connected with the upper inner tower, and the second driving motor is located in the second section rotor and connected with the lower inner tower. The rotor can adapt to the rotor submerging depth and adjust the rotating speed of the rotor. Therefore, wake flow loss behind the propeller is better absorbed, energy of the wake flow is converted into thrust, a traditional steering engine can be replaced, two functions are integrated on one device, and stern arrangement is optimized.

    本发明的目的在于提供一种船舶水下分段式辅助推进转子,包括内塔、第一段转子、第二段转子、第一驱动电机、第二驱动电机,内塔包括上内塔和下内塔,上内塔固定于船上,下内塔与上内塔通过联轴器联结在一起,第一段转子位于上内塔外部,第二段转子位于下内塔外部,第一段转子和第二段转子分别通过连接法兰连接各自的连接杆,各自的连接杆分别通过内塔轴承连接上内塔和下内塔,第一驱动电机位于船舱内并连接上内塔,第二驱动电机位于第二段转子内并连接下内塔。本发明能够适应转子淹深,调整转子转速。从而更好的吸收螺旋桨后的尾流损失,将其能量转化为推力,并又能代替传统的舵机,实现两种功能集成于一个设备上,优化了船尾布置。
