What is the purpose of the Reduction Gears?

The primary function of reduction gears is to convert high-speed, low-torque rotational energy produced by the ship's propulsion engines into low-speed, high-torque output suitable for driving the propeller(s). This conversion is essential because while engines generate a significant amount of RPM (revolutions per minute), propellers operate efficiently at lower RPMs but require greater torque to push the ship through the water effectively.

By using reduction gears, the mechanical advantage allows the propulsion system to operate efficiently, delivering the necessary torque for maneuverability and stability, which is critical for a vessel's performance at sea. Therefore, the purpose of reduction gears aligns with transforming the engine's output to meet the operational requirements of the ship's propulsion system.
