Abstract

The invention discloses a rim pump spraying driving device. The driving device comprises a water inlet flow guide chamber, a rotor and a water outlet flow guide chamber which are coaxially and sequentially arranged in a shell in the flowing direction of fluid, wherein blades are coaxially fixed to an inner ring of the rotor, a stator located in the shell is matched with the rotor in an electromagnetic induction mode, and a radial bearing is arranged on an inner ring of the stator to bear the radial load of the rotor; a first axial bearing is arranged between the rotor and the water inlet flow guide chamber to bear the axial load on one side of the rotor, and a second axial bearing is arranged between the rotor and the water outlet flow guide chamber to bear the axial load on the other side of the rotor. The driving device is advantaged in that the radial bearing is creatively arranged between the rotor and the stator, the axial length of the whole device is greatly shortened, the weight is greatly reduced, the space occupancy rate of the whole device is low, and light weight and miniaturization are achieved; as the axial bearing and the radial bearing are both water lubricated bearings, the whole device does not need any seal, and the driving device is simple in structure, convenient to assemble and high in safety and reliability.

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...
