The invention relates to a combined contra-rotating propeller electric propulsion system. The combined contra-rotating propeller electric propulsion system comprises a first motor, a shafting system,a first screw propeller and a rim type propeller. Propulsion efficiency is improved, the power of a large diesel engine which is high in price and limited in model selection range is delegated to a plurality of small-power generator sets through the mode of the electric propulsion system, so that a model selection range is expanded, and the initial installation cost of a power system is reduced. Arudder and propeller integrated type is adopted, the maneuverability of a ship is improved. The system is particularly suitable for medium and large ships.
本发明涉及一种组合式对转桨电力推进系统,包括:第一电机、轴系、第一螺旋桨和轮缘式推进器。本发明提高了推进效率,将价格昂贵、选型范围受到限制的大型柴油机的功率通过电力推进系统的型式,分摊为多台小功率的发电机组,扩大了选型范围,降低了动力系统的初装成本。采用了舵桨合一的型式,提高了船舶的操纵性,特别适用于中大型的船舶应用。
