Abstract

A ship drive with 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, as well as 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 a rotationally stiff, but axially pliant diaphragm coupling connected with the propeller shaft and the auxiliary bearing forms the play-free mechanically positive connection and in normal operation the auxiliary thrust bearing is clamped by means of pressure blocks against the flanges of the drive side and the thrust shaft.
