Abstract

The invention discloses a wheel rim pump jet driving device, which comprises a water inlet diversion chamber, a rotor and an outlet water diversion chamber which are coaxially arranged in a casing along the fluid flow direction. The stator in the body cooperates with the rotor by electromagnetic induction. The inner ring of the stator is provided with a radial bearing to bear the radial load of the rotor. Axial load, a second axial bearing is arranged between the rotor and the outlet water guiding chamber to bear the axial load on the other side of the rotor. In the present invention, the radial bearing is arranged between the rotor and the stator, the axial length of the whole device is greatly shortened, the weight is greatly reduced, the space occupation rate of the whole device is low, and light weight and miniaturization are realized; due to the axial Both the bearing and the radial bearing are water-lubricated bearings, the whole device does not need any seal, the structure is simple, the assembly is convenient, and the safety and reliability are high.

Description

technical field [0001] The invention relates to the field of thrusters, in particular to a wheel rim pump jet driving device. Background technique [0002] With the development of science and technology, the shaft-driven propeller, which is widely used in the underwater propulsion of ships, has been gradually replaced by the new type of rim pump-jet propeller due to its large energy loss, difficulty in controlling vibration and noise, and high construction and maintenance costs. replace. [0003] Due to the gradual miniaturization of current water craft, the excessive volume of the rim pump jet propeller is no longer suitable for miniaturized craft, and the structure occupies a large space and cannot meet the needs of miniaturization, so it needs to be solved urgently. Contents of the invention [0004] In order to avoid and overcome the technical problems in the prior art, the present invention provides a wheel rim pump jet driving device. The rim pump jet driving devic...
