According to the 360-degree full-rotation pod type underwater motor ship contra-rotating propeller propelling device, energy is saved by 20%, and the navigational speed and propelling efficiency are improved by 12% or above. An encoder, a special motor, a speed reducer and a reduction gear are adopted to achieve 360-degree full-rotation synchronization and non-synchronization whole-process electronic control of the propeller-rudder rotation body according to the advanced intelligent control theory, reversing is 1.6-1.8 times fast, and navigation is particularly safe. The underwater motor drives a transmission device to be connected with contra-rotating propellers, three components in the transmission device operate at the same time, the power and torque sharing proportion of the two contra-rotating propellers is calculated through the interdisciplinary innovation basic theory according to the speed ratio and the tooth number ratio, the contra-rotating propellers play the best energy-saving effect and efficiency in combination with the hydromechanics propeller pitch ratio theory, and the device is suitable for ships of any power type and military ships and boats, and solves the problems of high efficiency, energy conservation, environmental protection, noise reduction, vibration reduction and cost reduction of inboard and outboard ship contra-rotating propeller propelling devices which cannot be solved for many years are solved.

    360°全回转吊舱式水下电机船舶对转桨推进装置节能提高20%,航速和推进效率提高12%以上。采用编码器、特殊电机、减速机和减速齿轮以先进的智能控制理论实现桨舵回转体360°全回转同步、不同步全程电子操控,倒车快1.6‑1.8倍航行特别安全。水下电机带动传动装置连对转桨,传动装置内三构件同时运作,按速比、齿数比用交叉学科创新基础理论计算两对转桨功率和扭距分担比例,结合流体力学桨距比理论使对转桨发挥最佳节能效应和效率,适用任何功率类型船舶,军用船艇,攻克了多年无法解决的高效、节能、环保、降噪、降振、降成本舷内外船舶对转桨推进装置的难题。
