Introduction to Stern Shaft
A stern shaft, also known as a propeller shaft, is a crucial component in marine propulsion systems. It serves as the link between the ship's engine and the propeller, transmitting the power generated by the engine to the propeller, which in turn propels the vessel through the water. The stern shaft must be able to withstand high levels of torque, bending forces, and corrosion in the harsh marine environment. Therefore, the quality and performance of the stern shaft are of utmost importance for the safe and efficient operation of a ship.
