Abstract

The invention discloses a nacelle type shaftless rim driving integrated motor propeller. A permanent magnet motor stator and a permanent magnet motor rotor are installed in a guide pipe, the outer endof a propeller screw is connected to a rotor support, the inner end of the propeller screw is fixed to a center column, and a water gap is formed between the permanent magnet motor stator and the permanent magnet motor rotor to form an annular motor. Two sets of radial lath type water lubrication rubber alloy bearing supporting rotors are further arranged in the guide pipe, and a set of axial lath type water lubrication rubber alloy bearing is arranged to bear axial thrust. The beneficial effects of the propeller are that the propeller is modular, is convenient to install, is high in structural rigidity of the propeller screw, can bear a larger load, employs a built-in design mode for the stator winding power supply cable, and improves the safety of the cable; and a propeller bearing is subjected to forced water lubrication and cooling through the water pressure difference formed by the propeller, sealing of the bearing is omitted, cooling water flowing through a water gap between themotor stator and the motor rotor is driven through the water pressure difference formed by the propeller screw, and the overall structure is relatively simple.

Description

technical field [0001] The invention relates to the field of ship propellers, in particular to a pod type shaftless rim drive integrated motor propeller. Background technique [0002] With the rapid development of ship technology, people's requirements for ship propulsion devices have also been greatly improved. Traditional shaft drive propellers have shortcomings such as noise, vibration and layout, and can no longer meet the requirements of high-performance drive on the water surface and underwater. Therefore, Propellers with integrated motors and propellers have appeared. At present, there are mainly two forms: solid with hubs and hollow hubs. The U.S. patent document "IntegralMotor Propulsor Unit For Water Vehicles) (US005220231A) is a hollow shaft integrated motor propeller with a hollow shaft. The propeller is a ducted propeller. The motor stator winding is installed inside the duct. The rotor permanent magnet is installed externally, and the rotor propeller is instal...
