SHIP'S PROPULSION UNIT

摘要

The present disclosure relates to a ship's propulsion unit such as a ship's azimuthing propulsion unit. The propulsion unit can include at least one supporting metal sheet arranged between an support section of a shell structure of the propulsion unit and an cylindrical outer surface of a cylindrical section of a motor housing section of the shell structure for providing additional support for the motor housing section of the shell structure at the shell structure of the support section.

主权项

1. A ship's propulsion unit, comprising:
a shell structure configured to be arranged below a hull of the ship and immersible at least partly in water so that the shell structure is at least partly surrounded by water; and an electric motor for rotating a propeller axis, wherein the propeller axis extends to outside of the shell structure; a propeller mounted on the propeller axis outside the shell structure; wherein the propulsion unit has a vertical longitudinal central plane A; wherein the electric motor has a stator and a rotor for rotating in the stator; wherein the electric motor is arranged in a motor housing section of the shell structure so that the stator of the electric motor is form-fitted into a cylindrical section of the motor housing section of the shell structure, wherein the cylindrical section has a cylindrical outer surface; wherein the shell structure includes a support section having an lower end directly connected to the motor housing section of the shell structure and an upper end for connection to a hull of a ship, and wherein the motor housing section of the shell structure has a first end from which the propeller axis extends to the outside of the shell structure and a second end at an opposite end of the motor housing section of the shell structure, wherein at least one supporting metal sheet is arranged between the support section of the shell structure and the cylindrical outer surface of the cylindrical section of the motor housing section of the shell structure for providing additional support for the motor housing section of the shell structure at the shell structure of the support section; said at least one supporting metal sheet having a first side surface and a second side surface; and said at least one supporting metal sheet being fastened to the support section of the shell structure and fastened to the cylindrical outer surface of the cylindrical section of the motor housing section of the shell structure, such that when water surrounds the shell structure it will contact both the first side surface and the second side surface of said at least one supporting metal sheet.
