Abstract

The invention discloses a high-integration shaftless rim propeller for a ship. The high-integration shaftless rim propeller comprises a flow guide shell, a propeller assembly, a motor module and a motor driving control module. The propeller assembly comprises a propeller and a rim, the propeller and the rim are integrally arranged, the motor module comprises an inner rotor and an outer stator, the outer stator is arranged on the inner wall of the annular shell, the outer diameter face of the rim is fixed to the inner rotor, and the inner rotor drives the propeller to rotate when rotating. The motor drive control module is fixed in the diversion shell through screws and connected with one end of the outer stator through a wire, and the motor module and the motor drive control module are encapsulated in the diversion shell through resin glue. The electric motor, the shaft system, the propeller and the motor driving control module are integrated into a whole, and the integrated propeller has the advantages of being high in integration and power density and low in noise. Meanwhile, the specially-designed motor driving control module is arranged in the propeller, and the problems that a traditional propeller is long in communication line, large in interference, poor in consistency and large in heat dissipating capacity are solved.

Description

technical field [0001] The invention relates to the technical field of propellers, in particular to a highly integrated shaftless rim propeller for ships. Background technique [0002] Traditional propellers are all controlled by external devices, such as controlling the speed of the propeller mechanically or remotely. The problems caused by the separation of the control equipment and the propulsion equipment are that the communication line is long, the signal interference is large, and the transmission failure rate is high. In order to ensure good heat dissipation, the control module has a small power-to-volume ratio and poor integration. [0003] From a structural point of view, no matter whether the traditional propeller is powered by electricity or fuel, it needs a transmission shaft to drive the propeller to rotate to generate thrust, that is, a propulsion system formed by an engine, a transmission shaft and a propeller. This propulsion system is the current water vehi...
