Marine propulsion system and ship outfitted therewith, wherein the marine propulsion system has a propulsion element for propelling a ship, a driving engine which is to be flexibly mounted at a hull of the ship for driving the propulsion element, a thrust bearing which is to be rigidly mounted at the hull and which has a thrust bearing shaft having a first end and a second end, a driving engine drivetrain for connecting the driving engine to the first end of the thrust bearing shaft, and a propulsion element drivetrain for connecting the second end of the thrust bearing shaft to the propulsion element, wherein the driving engine drivetrain rigidly connects the driving engine to the first end of the thrust bearing shaft.

Ship propulsion system and ship equipped therewith

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.
