Claims (8)

1. Antriebsvorrichtung für Schiffe oder sonstige maritime Objekte mit gegenläufigen Propellern da­ durch gekennzeichnet, daß sie aus zwei gleichen oder ähnlichen Antriebsmodulen besteht, die jeweils in einem hydrodynamisch günstig geformten Rumpf (1) "Rücken an Rücken" angeordnet sind und gegenläufig drehen, wobei jedes Modul (11) aus einen Propeller (2), einer Propellerwelle (3), einem Elektromotor (4 + 5), zwei Traglagern (6) und einem Drucklager (7), oder einer Kombination davon mit den dazugehörigen Fun­ damenten (8) zusammengesetzt wird.1. Drive device for ships or other maritime objects with counter-rotating propellers since characterized in that it consists of two identical or similar drive modules, each arranged in a hydrodynamically shaped hull ( 1 ) "back to back" and rotating in opposite directions, each Module ( 11 ) composed of a propeller ( 2 ), a propeller shaft ( 3 ), an electric motor (4 + 5), two support bearings ( 6 ) and a thrust bearing ( 7 ), or a combination thereof with the associated funtions ( 8 ) becomes. 2. Antriebsvorrichtung für Schiffe oder sonstige maritime Objekte nach Anspruch 1 dadurch gekenn­ zeichnet, daß die beiden Propeller (2) an jedem Ende eines hydrodynamisch günstigen Rumpfes (12) montiert sind und gegenläufig drehen.2. Drive device for ships or other maritime objects according to claim 1, characterized in that the two propellers ( 2 ) are mounted at each end of a hydrodynamically favorable hull ( 12 ) and rotate in opposite directions. 3. Antriebsvorrichtung für Schiffe oder sonstige maritime Objekte nach Anspruch 1 dadurch gekenn­ zeichnet, daß die beiden Antriebsmodule (11) betriebsmäßig vollständig unabhängig sind und getrennt mit Energie versorgt werden.3. Drive device for ships or other maritime objects according to claim 1, characterized in that the two drive modules ( 11 ) are completely independent in operation and are separately supplied with energy. 4. Antriebsvorrichtung für Schiffe oder sonstige maritime Objekte nach Anspruch 1 dadurch gekenn­ zeichnet, daß der Rumpf (12), in welchem die beiden Antriebsmodule (11) untergebracht sind, an dem Unterwasser­ körper eines Bootes, Schiffes, Pontons oder einer Offshoreplattform fest-, dreh-, oder einziehbar mon­ tiert wird.4. Drive device for ships or other maritime objects according to claim 1, characterized in that the hull ( 12 ), in which the two drive modules ( 11 ) are housed, on the underwater body of a boat, ship, pontoons or an offshore platform, rotatable, or retractable is installed. 5. Antriebsvorrichtung für Schiffe oder sonstige maritime Objekte nach Anspruch 1 dadurch gekenn­ zeichnet, daß die beiden Elektromotoren (4 + 5), die jeweils einen gegenläufigen Propeller (2) antreiben vollständig getrennt und co-axial sind, wobei bei jedem Motor der Rotor (4) an der Propellerwelle (3) und der Stator (5) an dem hydrodynamisch günstigen Rumpf (1) befestigt wird. 5. Drive device for ships or other maritime objects according to claim 1, characterized in that the two electric motors (4 + 5), each driving a counter-rotating propeller ( 2 ) are completely separate and co-axial, with each motor, the rotor ( 4 ) on the propeller shaft ( 3 ) and the stator ( 5 ) on the hydrodynamically favorable hull ( 1 ). 6.

Drive device for ships or other maritime objects according to claim 1 characterized thereby records that no concentric shafts, no special bearings and special seals between the con centric shafts and no planetary, spur or bevel gear required. 7. Antriebsvorrichtung für Schiffe oder sonstige maritime Objekte nach Anspruch 1 dadurch gekenn­ zeichnet, daß bei einem Schiff oder sonstigem maritimen Objekt, Neubau oder Umbau, ausgerüstet mit einem, zwei oder mehreren konventionellen Propellern (15) nebeneinander, jeweils hinter jedem Propeller nur ein Antriebsmodul (11) in dem dazugehörigen Rudersporn (14) oder einer dazu geeigneten Konstruktion befestigt wird, und dessen Propeller (2) co-axial und gegenläufig zu dem entsprechenden konventio­ nellen Propeller (15) dreht.7. Drive device for ships or other maritime objects according to claim 1, characterized in that in a ship or other maritime object, new construction or conversion, equipped with one, two or more conventional propellers ( 15 ) side by side, each behind each propeller only one drive module ( 11 ) in the associated rudder spur ( 14 ) or a suitable construction is attached, and its propeller ( 2 ) co-axially and in opposite directions to the corresponding conventional propeller ( 15 ) rotates. 8. Antriebsvorrichtung für Schiffe oder sonstige maritime Objekte nach Anspruch 1 dadurch gekenn­ zeichnet, daß zwei Antriebsmodule (11) vorgesehen werden, wobei einer in dem Rudersporn (14) oder einer dafür geeigneten Konstruktion und das andere in dem Hintersteven (16) eines mehr oder weniger konven­ tionellen Schiffes, Neu- oder Umbau, eingebaut werden, nachdem der konventionelle Propeller (15) eliminiert wird, wobei die Propeller (2) der Antriebsmodule (11) gegenüber und co-axial stehen und gegenläufig drehen.8. Drive device for ships or other maritime objects according to claim 1, characterized in that two drive modules ( 11 ) are provided, one in the rudder spur ( 14 ) or a suitable construction and the other in the stern post ( 16 ) of a more or less conventional ship, new or rebuilt, installed after the conventional propeller ( 15 ) is eliminated, the propellers ( 2 ) of the drive modules ( 11 ) are opposite and co-axial and rotate in opposite directions.
