Abstract

The invention belongs to the field of ship industries and relates to a bow side propelling device used for a ship and driven by a wheel flange type permanent magnet motor. The bow side propelling device comprises the wheel flange type motor, a supporting structure and a propeller, the supporting structure comprises a shaft system and bearing seat supports, and the shaft system is arranged in the middle of the inner side of a shell of the wheel flange type motor in the horizontal direction. The two ends of the shaft system are provided with the bearing seat supports, and the bearing seat supports are connected with the inner wall of the shell of the wheel flange type motor and used for supporting the shaft system. The propeller is located between the bearing seat supports at the two ends of the shaft system, and a hub of the propeller is connected with the shaft system. Blades of the propeller are connected with the inner wall of a rotor of the wheel flange type motor to enable the rotor to drive the propeller to rotate. According to the bow side propelling device used for the ship and driven by the wheel flange type permanent magnet motor, the wheel flange type permanent magnet synchronous motor placed under water is used for directly driving the propeller, the intermediate gear transmission link is omitted, mechanisms such as a complex gear box and a hoisting column are removed, and the bow side propelling device has the characteristics that the propelling efficiency is high, the service life is long, and the sealing and anti-leaking effects are achieved.

Description

technical field

[0001] The invention belongs to the field of ship industry, and relates to a bow thruster part of a ship auxiliary engine, in particular to a ship bow thruster driven by a rim type permanent magnet motor. Background technique

[0002] Marine bow thrusters are generally applied to ships with longer captains, or ships with higher maneuverability / handling requirements, the former such as inland river or ocean transport ships, and the latter such as ocean engineering ships, public law enforcement ships, and warships. It is generally installed on the bow of the ship to provide lateral thrust and assist steering, so it is called bow thruster. There are also side thrusters installed on the bow and stern of the ship to achieve better maneuverability. Some side thrusters are also equipped with lifting and full-turn mechanism, so as to play the role of all-round propulsion.

[0003] The traditional bow thruster is usually driven by a variable frequency motor. The var...
