Gears - Delivering power to propulsion

    The marine reduction gear is a key element of the propulsion system, enabling the main engine and the propeller to operate at optimum speeds. Other functions such as a propeller thrust bearing, multiple-disc clutches, power take-off for shaft generators and power take-in for electric motors can also be incorporated in the gear.
