The invention discloses a marine outboard motor with low rotating speed output, and the motor comprises an engine and an outboard motor mainly composed of a propeller, wherein the engine is connectedwith the propeller through a speed reducing mechanism used for reducing the rotating speed of the propeller to 300-700 revolutions. According to the low-rotating-speed output marine outboard motor adopting the structure, the belt speed reduction unit, the upper gear box speed reduction assembly and the lower gear box speed reduction assembly in the speed reduction mechanism are adopted, so three-stage speed reduction between the engine and the propeller is realized, and the engine and the propeller can realize speed reduction transmission between 2.5: 1 and 5: 1; therefore, high-rotating-speedpower output by the engine can be converted into low-rotating-speed and large-torque power to be output to the propeller, the diameter of blades of the propeller can be increased, large thrust and high navigational speed are provided for a ship, the driving efficiency is improved, and the beneficial effects of energy conservation and consumption reduction are achieved.

    本发明公开了一种低转速输出船用挂桨机,包括发动机和主要由螺旋桨组成的挂桨机,所述发动机经用于将所述螺旋桨的转速降至300‑700转之间的降速机构与所述螺旋桨连接。本发明采用上述结构的低转速输出船用挂桨机,采用降速机构中的皮带降速单元、上齿轮箱降速组件和下齿轮箱降速组件,实现了发动机到螺旋桨之间的三级降速,使得发动机与螺旋桨能够在2.5:1至5:1之间降速传动,进而可将发动机输出的高转速动力转换为低转速、大扭矩力输出至螺旋桨,可增大螺旋桨桨叶直径,为船只提供大推力和高航速,提高驱动效率,从而达到节能降耗的有益效果。
