Abstract

PURPOSE: To facilitate the alignment and maintenance, etc for the shaft system, to improve propelling efficiency, and to save energy for ship in such a way that adoption of low rotation big diametral propeller is made available by transmitting power from one unit of the main engine to plural propellor shafts.
CONSTITUTION: Power of an output shaft 3 of the main engine 2 is transmitted through a decelerator 4 to each propeller shaft 5. In case of one engine two shaft system, in comparison with one engine one shaft ship, if the diameter of the propellers is made the same together, output per shaft is made half, which makes it possible to reduce the number of rotation. In that case, through the diameter of the shaft is in the trend of magnifying, as the output is half, the shaft system weight has not much difference as hitherto, special problem does not occur referring to the alignment. In addition, in comparison with conventional two engine two shaft ship which is the same in the propeller diameter and the main engine power is respectively half, even though the propelling efficiency is practically the same, it can make the arrangement of the equipment advantageous. Further, also from the point of view on the maintenance, since the main engine number is changed from two units to one unit, it is obvious that it is much more profitable.
