Title:
MODULARIZED MAGNETIC-COUPLING ELECTRIC PODDED PROPULSOR
Document Type and Number:
WIPO Patent Application WO/2024/016673
Kind Code:
A1
Abstract:
A modularized magnetic-coupling electric podded propulsor, comprising a box body (101), a main pod body (201) and a turbine cabin (301). The box body (101) is mounted on an outer circumferential surface of the main pod body (201) and is in communication with the interior of the main pod body (201) by means of pipes; an electric motor (202) and a magnetic coupling disc I (205) are arranged in the main pod body (201), and an electric motor main shaft (204) is coaxially connected to the magnetic coupling disk I (205); a turbine main shaft (305) and a magnetic coupling disc II (304) are arranged in the turbine cabin (301), the turbine main shaft (305) is mounted in the turbine cabin (301) by means of a bearing, one end of the turbine main shaft is coaxially connected to the magnetic coupling disc II (304), and one end of the turbine cabin (301) is connected to one end of the main pod body (201) by means of a flange disc (302), so that the magnetic coupling disc I (205) and the magnetic coupling disc II (304) are coaxially spaced apart and opposite each other and are magnetically attracted to each other; turbine blades (306) are arranged on the periphery of the turbine cabin (301); and inner rings of the turbine blades (306) extend into the turbine cabin (301) and are connected to the turbine main shaft (305). Torque is transmitted between the main pod body and the turbine cabin of the podded propulsor by means of magnetic coupling; and the electric motor main shaft does not have a complex dynamic sealing structure, and the main pod body is completely statically sealed, such that there is no risk of water seepage, and the reliability of the apparatus can be improved.
