The invention relates to a pump jet propeller without a transmission shaft, and belongs to the technical field of ship propellers. The pump jet propeller is characterized in that a front stator and arear stator are fixedly connected to the front end and the rear end of a hollow stepped shaft in a base respectively, and the outer ends of blades of blade sets on the two stators are fixedly connected with the front portion and the rear portion of an inner ring of a guide pipe correspondingly, and a rotor is movably connected to the middle portion of the hollow stepped shaft of the base through abearing; coils are fixedly connected into the guide pipe and cavities of all the blades on the two stators, and are connected with a power supply through wires; no complex transmission shaft system exists, so that mechanical vibration and noise of the shaft system can be eliminated; the guide pipe can shield noise generated by the rotor and an inner flow channel; the front stator enables water flow entering the rotor to generate prewhirl, so that the water flow becomes more uniform, and the propelling efficiency can be improved; and the rear stator can recover part of rotating energy in wakeflow, so that noise is reduced, and mechanical vibration and noise of the shaft system can be eliminated due to the fact that the complex transmission shaft system is omitted. The pump jet propeller is wide in application range and can be used on various devices such as submarines, torpedoes and underwater vehicles.

    一种无传动轴泵喷推进装置属船舶推进器技术领域,本发明中前后两个定子分别固接于基座中空心阶梯轴的前后两端,两个定子上叶片组的叶片外端分别与导管内圈的前后部固接,转子经轴承活动连接于基座中空心阶梯轴的中部,导管和两个定子上所有叶片的空腔中均固接有线圈,线圈经导线与电源连接;无复杂的传动轴系,可消除轴系的机械振动和噪声;导管可屏蔽转子及内流道产生的噪声;前置定子可使进入转子的水流产生预旋,变得更为均匀,能提高推进效率;后置定子可回收尾流中的部分旋转能量,从而降低噪声,无复杂的传动轴系可消除轴系的机械振动及噪声。本发明的用途广泛,可在潜艇、鱼雷、水下潜航器等各类设备上使用。
