Marine Stern Tube
The stern tube is a metal tube welded to the hull, connecting the engine room and the outside of the ship. It houses the propeller shaft, which transmits power from the ship's engine to the propeller, enabling the vessel to move.
The front and rear ends of the stern tube shall be stuffed to ensure its water tightness.
Overview
There is only one stern shaft tube in traditional ship layout, but it is possible to have two or even three in some other applications. They are usually placed symmetrically on either side of the ship's midline, so that the thrust can push the ship forward in a straight line. It has sealing apparatus to prevent oil leakage and water form entering the vessels. It allowed to be lubricated by oil or water.
The marine stern tube is an essential part of a ship's propulsion system, providing support and protection to the propeller shaft. It ensures the smooth transfer of power from the engine to the propeller while maintaining the watertight integrity of the ship. Proper maintenance and alignment are critical to its efficient operation and longevity.
