Abstract

With this power take-off gearing, intended to be installed at a propulsion system or drive of a marine vessel, there can be taken-off part of the vessel's drive output at one or a number of auxiliary drive units. The drive or propulsion system of the vessel is mounted upon the ship's foundation and essentially comprises a main engine, a speed reduction gear unit containing a power take-off shaft, a multi-part propeller shaft which extends through a power take-off gearing, and a propeller attached to the propeller shaft. The power take-off gearing is arranged in a housing and supported as a self-contained unit upon the ship's foundation independent of the propeller shaft. A large gear mounted in the housing of the power take-off gearing is driven by the propeller shaft through a moveable clutch which is constructed as a double tooth clutch. The power take-off gearing is connected with a generator.
