Introduction to Stern Shaft
A stern shaft, also known as a propeller shaft, is a crucial component in the propulsion system of a ship. It serves as the link between the ship's engine and the propeller, transmitting the power generated by the engine to the propeller, enabling the ship to move forward or backward. The stern shaft operates under high - torque and high - speed conditions, often in harsh marine environments, so it requires high - quality materials and precise manufacturing processes to ensure its reliability and durability.
