DRIVE UNIT OF A SHIP FOR ICY WATERS

摘要

A drive unit of a ship for icy waters has a propeller, a prime mover, a shaft line between the prime mover and propeller, and a flywheel element which is arranged on the shaft line and can be coupled with the latter by a hydrodynamic switch coupling. The flywheel is formed as a rotation symmetrical tubular body which concentrically surrounds the shaft line.
