Introduction to Rudder Stock
A rudder stock is a crucial component of a ship's steering system. It is a vertical shaft that connects the rudder blade to the steering gear on the ship. The rudder stock transfers the torque from the steering gear to the rudder blade, enabling the ship to change its direction. It needs to be made of high - strength materials to withstand the significant forces exerted during the ship's operation, including the hydrodynamic forces acting on the rudder blade and the mechanical forces from the steering mechanism. The quality and performance of the rudder stock directly affect the safety and maneuverability of the vessel.
