Abstract
The invention discloses a ship flange integration propulsion device. The ship flange integration propulsion device comprises a motor stator assembly, a motor rotor assembly, a propeller assembly, a guide tube, a rear guide cover, a front guide cover, a first water lubricated bearing, a second water lubricated bearing, an axle, a rear propeller hub cap, a front propeller hub cap, front guide cover connecting plates, rear guide cover connecting plates, a front end cover, a rear end cover and a fiber reinforced polymer sleeve, wherein the front end cover, the rear end cover and the fiber reinforced polymer sleeve are used for sealing the stator assembly, a closed space is formed among the stator assembly, the guide tube, the front end cover, the rear end cover and the fiber reinforced polymer sleeve, and the closed space is filled with epoxy resin. A static sealing structure is formed between the motor stator assembly and the guide tube, the sealing effect is good, and the technical problem that in the prior art, seawater may enter a stator can be effectively solved. In addition, due to the fact that a flange structure mode is adopted, paddles transmit hydrodynamic load at paddle tip conveniently; meanwhile, tip vortex is avoided, and the propulsive efficiency is further improved.
Description
technical field [0001] The invention relates to a ship propulsion device, in particular to a ship rim integrated propeller. Background technique [0002] At present, the existing full-turn pod propulsion system consists of a slewing device, a pod, and a propulsion device suspended at the lower part of the hull, and the shafting and rudder of the traditional propeller are omitted. Its propulsion device is installed inside the pod, and the rotor shaft of the propulsion motor is connected with the propeller shaft on the same straight line. The slewing device can allow the propeller to rotate 360 degrees in water, so that the propeller can generate thrust in any direction, achieve good maneuverability, and play the role of the rudder of a conventional ship. Compared with the defects of low efficiency and poor maneuverability of the traditional diesel engine-driven propeller, the azimuth pod propulsion system has the advantages of low vibration, good maneuverability and space ...
