A propeller drive arrangement for controlling and driving a ship (1) is proposed, comprising at least one drive motor (3) arranged in the hull (2), comprising at least one gearbox (5), and further comprising at least one control case (7) having at least one propeller (8) on an output shaft (6), wherein the gearbox (5) and the control case (7) are arranged outside of the ship's hull (2), and wherein the control case (7) is arranged pivotably on the gearbox (5) for controlling the ship (1) via a control shaft. According to the invention, the gearbox (5) is arranged substantially below a stern platform (10).

Description

 Propeller drive arrangement for controlling and driving a ship

The present invention relates to a propeller drive arrangement for controlling and driving a ship according to the closer defined in the preamble of claim 1. Art.

So-called pod drives for ships are known. Such drives are propeller drive arrangements for controlling and driving a ship, the z. B. have a streamlined nacelle as the control housing, which is rotatable or pivotable for controlling the ship about the vertical axis. The propeller drive assembly includes a transmission in a transmission housing, wherein the transmission is coupled to a motor via a drive shaft. Both the transmission housing and the engine are arranged in the hull. By contrast, the control housing with at least one propeller is arranged in the water, ie outside the hull.

Such a propeller drive arrangement is known, for example, from document US Pat. No. 7,033,234 B2. Each propeller drive assembly includes two propellers on the control housing. The control housing is attached to a V-shaped bottom of the hull. The axis of the control shaft is perpendicular to the surface of the V-shaped bottom of the hull on which the respective control housing of the propeller drive assemblies is mounted. Thus, the installation of the control housing requires an opening in the bottom of the hull. Further, the transmission housing is disposed inside the hull, so that the positions of the drive motor is set in the rear area.

In addition, US Pat. No. 7,294,031 B1 also discloses propeller drive arrangements for driving and controlling a ship. These propeller drive arrangements are also compatible with their control housings. seπ attached to the bottom of the hull. However, in the area of
