Shaft
In maritime and seamanship context, a shaft refers to a rotating mechanical element that transmits power from the engine to the propeller. It is a critical component of the propulsion system of a ship. The shaft is usually made of high-strength steel and is supported by bearings that allow it to rotate smoothly. The shaft is connected to the engine through a coupling and to the propeller through a stern tube. The alignment of the shaft is crucial for the efficient operation of the propulsion system. Misalignment can cause vibration, noise, and damage to the bearings and seals. The shaft is also subject to corrosion and fatigue, which can lead to failure and loss of propulsion.
