The invention discloses a double-layer diffusion and sawtooth tail edge integrated wheel rim driving propeller. The propeller comprises a multiplier assembly, a sawtooth tail edge, a multiplier connecting assembly, a stator winding and a rotor assembly. The multiplier assembly comprises a double-layer diffusion structure composed of a first-stage multiplier and a second-stage multiplier, the sectional area of the structure in the middle of the guide pipe is minimum, the sectional areas of the structure at the two ends of the guide pipe are large, and the flow speed of water flowing through propeller blades can be obviously increased. Due to the design of the sawtooth tail edge, the water flow noise is greatly reduced; the wheel rim driving mode is free of complex shafting transmission, and shafting vibration is reduced while the propulsive efficiency is greatly improved. The propeller has the advantages of improving the propulsive efficiency, reducing the noise, reducing the vibration and the like, and is particularly suitable for military ships with higher requirements on maneuverability and concealment.

    本发明公开了一种双层扩散和锯齿尾缘一体化的轮缘驱动推进器,该推进器包括增效器组件、锯齿型尾缘、增效器间连接组件、定子绕组和转子组件。增效器组件包括一级增效器和二级增效器组成的双层扩散结构,这种结构在导管中部的截面积最小而在导管两端截面积较大,可以明显加快流经推进器桨叶的水流流速;锯齿型尾缘的设计大幅降低了水流噪声;轮缘驱动方式无复杂轴系传动,在极大提高推进效率的同时减小轴系振动。本发明具有提高推进效率、降低噪声、减小振动等优点,特别适用于对机动性和隐蔽性要求较高的军用舰船上。
