与现有技术相比， 本发明的优点在于： 把电机的技术与泵的技术结合在一起， 改变 了现有技术中航行器 (船舶)的喷水推进装置轴流泵、 以及螺旋桨的旋转力矩方式， 由传 统的靠桨心上的转轴旋转而改为从桨叶梢上的管套转体来实现旋转； 由于工作时， 通过 电磁效应实现桨 (扇)叶旋转， 使得船舶的主机与螺旋桨、 轴流泵之间可以不用机械转轴 硬接， 为船舶提供无转轴推进装置， 使得船舶的机舱设计可以更加灵活。 并且本发明的 电动 (螺旋桨、 轴流泵)机， 由于电动机可以有反向逆转以及可调速， 由此可以取消倒顺 减速齿轮装置， 并且使采用本发明的电动机作喷水推进装置的船舶在设计上可以取消倒 斗装置。 Compared with the prior art, the advantages of the invention are: combining the technology of the motor with the technology of the pump, changing The axial flow pump of the water jet propulsion device of the prior art aircraft (ship) and the rotary torque mode of the propeller are changed from the conventional rotary shaft on the propeller shaft to the sleeve rotation on the blade tip. Realize the rotation; Because of the electromagnetic effect, the paddle (fan) leaf rotation is realized, so that the main engine of the ship and the propeller and the axial flow pump can be hardly connected without the mechanical rotating shaft, and the ship is provided with the shaftless propulsion device, so that the cabin design of the ship is made. Can be more flexible. Further, in the electric (propeller, axial flow pump) machine of the present invention, since the electric motor can be reversely reversed and adjustable, the reverse reduction gear unit can be eliminated, and the motor using the electric motor of the present invention as the water jet propulsion device can be used. The bucket device can be eliminated in design.
本发明的电动机如果解决好冷却、 散热技术问题， 并采用航空材料制造， 本发明的 电动机也可以作航空发动机用， 由于采用电技术， 与现有的航空发动机相比， 没有尾喷 热源， 可以使飞行器在制造设计上， 可作能像十字标作上下、 前后、 左右 129600度移 动操作、 并且同时可作下海潜水操作。  If the motor of the present invention solves the cooling and heat dissipation technical problems and is manufactured by aeronautical materials, the motor of the present invention can also be used as an aeroengine. Due to the use of electric technology, there is no tail spray heat source compared with the existing aero engine. In the manufacturing design, the aircraft can be operated like a cross mark up and down, front and rear, left and right, 129600 degrees, and at the same time can be used for diving operations.
由于螺旋桨、轴流泵的旋转力矩传递方法由传统转轴改为管套转体方式，改变了螺 旋桨的旋转力矩由轴中心 (桨毂)内径传递改成桨叶梢、 外径传递， 比较管套转体与转轴 效果， 依据杠杆的力学平衡理论； 设螺旋桨轴流泵的轴中心为一个支点， 船舶主机的活 塞行程为杠杆一边的长度。  Since the rotary torque transmission method of the propeller and the axial flow pump is changed from the conventional rotary shaft to the sleeve rotation mode, the rotation torque of the propeller is changed from the inner diameter of the shaft center (the hub) to the blade tip and the outer diameter transmission, and the sleeve is compared. The turning and rotating shaft effect is based on the mechanical balance theory of the lever; the shaft center of the propeller axial flow pump is a fulcrum, and the piston stroke of the main engine is the length of one side of the lever.
管套转体的外径为杠杆另一边的长度，那么管套转体的外径与活塞行程的比值，就 是管套转体的效果参数， 因此， 同一参数的螺旋桨、 轴流泵如果其需要 1万马力轴功率 时， 其管套转体系例的螺旋桨、 轴流泵的电机输出功率至少可以缩小至 4千马力至 1千 马力之间甚至于更小。 这样当一台螺旋桨、 轴流泵其需要 1万马力轴功率主机时， 其可 以用二千马力的主机带动发电机， 再经电动机的电磁效应带动管套转体从而带动螺旋桨 旋转， 不仅提高了船舶的能源效率， 实现节能降耗， 而且管理简单方便。 附图说明  The outer diameter of the sleeve swivel is the length of the other side of the lever, then the ratio of the outer diameter of the sleeve to the piston stroke is the effect parameter of the sleeve swivel. Therefore, if the same parameter of the propeller or axial pump is needed When the power of 10,000 horsepower is used, the output power of the propeller and axial pump of the sleeve-turning system can be reduced to at least 4 kilowatts to 1 kilo horsepower or even smaller. In this way, when a propeller or axial flow pump needs a 10,000-horsepower shaft power main engine, it can drive the generator with a 2,000-horsepower main engine, and then the electromagnetic effect of the electric motor drives the sleeve to rotate, which not only improves the rotation of the propeller, but also improves the The energy efficiency of the ship achieves energy saving and consumption, and the management is simple and convenient.
