The invention provides a ship shaftless propelling system combined with a fin stabilizer. The ship shaftless propelling system comprises a shaftless propeller, fin stabilizers and a variable frequency driving device. The shaftless propeller is fixedly connected with the outer end part of a fin stabilizer fixed fin shaft and is used for propelling; the fin stabilizers are installed on the two sides of the ship body through the fixed fin shafts and used for improving the stability of the ship. And the variable frequency driving device is mounted in the ship and is used for controlling the rotating speed of the shaftless propeller. The fin stabilizer is designed to be of a middle shaft penetrating type, a middle shaft is fixedly connected with the propeller, and the fin stabilizer rotates around the middle shaft. A traditional stern propeller propulsion mode is expanded to a middle power fin propulsion mode, and the power mode is expanded by combining the design of the fin stabilizer and the thruster. Compared with a common ship propulsion technology, the ship propelling system is an electric propulsion mode for supplementing a conventional propulsion mode, expands a traditional power mode, and greatly improves the sound stealth performance, the maneuvering performance and the transformation potential of an existing ship on the basis of achieving low-navigational-speed propulsion.

    本发明提出了一种与减摇鳍合并设计的舰船无轴推进系统,包括无轴推进器、减摇鳍、变频驱动装置;所述无轴推进器与减摇鳍固定鳍轴外端部固定连接,用于推进;所述减摇鳍通过固定鳍轴安装在船体两侧,用于提高舰船稳性;所述变频驱动设备安装在舰船内部,对无轴推进器进行转速控制。所述减摇鳍设计为中间穿轴型式,中间轴与推进器固定连接,减摇鳍绕中间轴旋转。通过将传统的艉部螺旋桨推进方式扩展到中部动力鳍推进型式,结合减摇鳍和推进器的设计,扩展了动力型式。与常见舰船的推进技术相比,本发明是对常规推进方式的一种电力推进方式补充,扩展了传统的动力型式,在实现低航速推进的基础上,大幅提高声隐身性能、机动性能和现有舰船改造潜力。
