The invention aims at providing an electric contra-rotating propeller propelling pod which comprises a pod shell, a driving motor is arranged in the pod shell, the first end of the driving motor is connected with a reverse rotating propeller through a reverse rotating planetary reducer, and the second end of the driving motor is connected with a forward rotating propeller through a forward rotating planetary reducer. A reverse thrust bearing is arranged between the reverse planetary reducer and the reverse propeller, and a forward thrust bearing is arranged between the forward planetary reducer and the forward propeller. A conventional double-output medium-speed rotating speed motor is adopted as a power source of the pod, and the problem that a low-speed special motor is high in manufacturing cost is solved; two types of planetary reducers are adopted for speed reduction, and contra-rotation of paddles is achieved by means of the characteristic that the output rotation directions of different planetary reducers are different. And on the other hand, due to high planetary transmission power density and strong torque transmission capability, the problem that the power of a traditional pod is difficult to increase is solved.

    本发明的目的在于提供一种电动对转对转桨推进吊舱,包括吊舱壳体,吊舱壳体里设置驱动电机,驱动电机的第一端通过反转行星减速器连接反转桨,驱动电机的第二端通过正传行星减速器连接正转桨。反转行星减速器与反转桨之间设置反转推力轴承,正转行星减速器与正转桨之间设置正转推力轴承。本发明采用一台常规双输出中速转速电机作为吊舱的动力源,解决了低速特种电机造价高的问题;采用两种类型行星减速器降速,利用不同行星减速器输出旋转方向不同的特点,实现了桨的对转;另一方面由于行星传动功率密度高,传扭能力强,解决了传统吊舱功率难以做大的难题。
