A drive system includes a drive shaft with first and second shaft sections connected by a diaphragm clutch having a diaphragm assembly. The radially outer end of the diaphragm assembly is connected to a disk having a first toothing arranged on one face of the disk. The first toothing engages in corresponding second toothing on a flange connected to the first shaft section when the diaphragm assembly is subjected to an axial preload. A contact-pressure device that is controllable by remote control in the stationary condition acts against the disk to produce the preload.

Drive system

A Marine drive mechanism has a twin-engine distribution transmission for driving a propeller-shaft train (,) supported on bearings (,). The drive mechanism (,) and the transmission (,), which is rigidly connected to it, being fastened to the bottom (,) of the hull. A pressure bearing (,) accommodates and transmits the thrust exerted by the propeller (,) by way of the propeller-shaft train. A coupling (,) engages and disengages the drive mechanism. The drive mechanism and the transmission are individually supported, the drive mechanism by resilient supports (,) and the transmission by resilient supports (,) and resilient bearings (,). The pressure bearing is built into the transmission. The transmission bearings (,) are integrated into a separate post (,) rigidly fastened to the bottom and are attached to the walls (,) of the transmission.

Marine drive mechanism with twin-engine distribution transmission

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 (,) connected with the propeller shaft (,) and the auxiliary thrust bearing forms the play-free, mechanically positive connection and in normal operation the auxiliary thrust bearing is clamped by means of the pressure blocks (,) against the flanges (,) of the drive side and the thrust shaft (,). For quick release of the cone pins (,) arranged in the flange holes of the flanges (,) of the diaphragm coupling a guide device (,) is mounted, wherein the pins (,) after release of the nuts (,) are journalled to be radially and axially movable in the guide device (FIG.,).
