Abstract

There is indicated a ship drive consisting of a drive engine and a propeller shaft which is directly connected therewith and provided with a propeller and the thrust of which is taken up by a thrust bearing. In addition, there is provided an auxiliary drive consisting of an electric engine which is to operate selectably as a generator or a motor and which is connected with a transmission by way of a clutch. In that case a gearwheel of the transmission surrounds the propeller intermediate shaft and is connected therewith by way of a flexible coupling. A play-free, releasable and mechanically positive connection is arranged between transmission and the drive engine, which has a flange at the drive side, on a thrust shaft and is combined with an auxiliary thrust bearing, which has forward and reverse pressure blocks and which is activatable in the case of auxiliary or emergency operation of the ship. In that case, the correspondingly reduced propeller thrust is introduced by way of the auxiliary thrust bearing to a thrust bearing, which is arranged in the drive engine, into the ship hull. A rotationally stiff, but axially pliant diaphragm coupling (4) connected with the propeller shaf…
