Abstract

The invention discloses a novel AUV (autonomous underwater vehicle) water-jet propeller, which comprises a power input gearbox and two vane-type centering rotor displacement pumps. A power input shaftof the power input gearbox is supported on a first middle end cover through bearings and a mechanical seal. One end of the power input shaft is connected with a power output shaft, a gear is fixed tothe other end of the power input shaft and matched with a spiral bevel gear on a spindle, and the first middle end cover and a second middle end cover are matched with boxes of the two vane-type centering rotor displacement pumps. The novel AUV water-jet propeller has advantages that power is transmitted to the spindle through the power input shaft and the spiral bevel gear and further transmitted to the two vane-type centering rotor displacement pumps, and accordingly a whole underwater vehicle propelling process is realized.

Description

technical field [0001] The invention relates to the technical field of thrusters, in particular to a novel AUV water jet propeller. Background technique [0002] The notification number CN201363270 discloses a water jet propeller-vane rotor pump, which has the advantages of small size, light weight, high power density, large speed regulation range and high efficiency without degradation. The rotor and blades of the vane rotor pump are supported in a fixed position in the box, and their tolerances can be guaranteed during processing; during operation, the ends of the blades with lighter weight are in contact with the inner wall of the housing, while the rotors with greater mass are in contact with the inner wall of the housing. The internal wall is not in contact and wear-free, which improves the service life of the mechanism; each part rotates around its own central axis, and the dynamic change of its moment of inertia is also small, so the mechanism can be at a higher rotat...
