Abstract

The invention discloses a marine electromagnetic counter-rotating hub-type rim water jet propeller, which comprises a water spray pipe, an annular permanent magnet motor device, a counter-rotating rim propeller, a bearing assembly and a sealing assembly; wherein, the water spray pipe includes a shell The body and the water outlet and water inlet arranged at both ends of the shell; the annular permanent magnet motor device and the counter-rotating rim propeller are arranged on the shell near the water outlet; the counter-rotating rim propeller includes a first-stage rim propeller and a second-stage rim propeller The rim propeller, the first-stage rim propeller and the second-stage rim propeller are connected to each other through a bearing assembly; there are two annular permanent magnet motor devices, which are respectively arranged on the outer shell of the first-stage rim propeller and the second-stage rim propeller On the body; the annular permanent magnet motor device and the bearing assembly are provided with a sealing assembly. The invention has the advantages of high maneuverability, high propulsion efficiency, high ship stability, low vibration and noise, high strength, safety and reliability, and the like.

Description

technical field [0001] The invention relates to the technical field of ship propellers, in particular to a marine electromagnetic counter-rotating wheel rim water jet propeller. Background technique [0002] As the performance requirements of ship propulsion devices are getting higher and higher, the traditional shaft-propeller drive device has many components, takes up a lot of space in the cabin, consumes a lot of energy, and it is difficult to control the vibration and noise of the shafting system. Especially for compact ships such as boats and submarines, the cabin space is limited, and high maneuverability and stable and reliable shafting are required. The water jet propeller has a series of advantages such as small radius of gyration, low noise and vibration in the ship cabin, and simple structure, and is widely used in yachts, hovercraft, and military ships. The existing water jet propulsion mostly adopts the pump shaft propulsion method, and the blades are fixed on ...
