ABSTRACT:
A ship gear train arrangement includes a differential gearing between a main input shaft and output shaft and a parallel shaft with a hydrodynamic coupling (50). The parallel shaft connects a point (at 60) of the main input shaft on the input side (30) of the differential gearing with a reaction element (16) of the differential gearing. The coupling effect and thus also the speed of output shaft (32) of the ship gear train arrangement can be changed smoothly down to zero speed by variation of the liquid level in the hydrodynamic coupling. The ship propeller can therefore be driven at a speed far lower than the lowest speed of the ship main drive motor.
