This arrangement inevitably results for the associated ring gear and the underwater housing has a diameter which reaches about 40% of the propeller diameter.

Eine vorteilhafte Weiterbildung davon besteht darin, dass zwischen dem Planetengetriebe und den Antriebsmotoreinrichtungen ein weiteres Getriebe angeordnet ist, wobei vorzugsweise das weitere Getriebe ein Tellerrad-Kegelrad-Getriebe ist, das insbesondere einen Kegelradsatz enthält.An advantageous development of this is that between the planetary gear and the drive motor means another gear is arranged, wherein preferably the further gear is a crown gear bevel gear, which contains in particular a bevel gear.

Dabei kann ferner mit Vorzug vorgesehen sein, dass zwischen dem Planetengetriebe und dem weiteren Getriebe, insbesondere ggf. der Kegelradstufe, eine hydrodynamische Kupplung oder ein hydrodynamischer Wandler angeordnet ist.It can also be provided with preference that between the planetary gear and the further transmission, in particular possibly the bevel gear, a hydrodynamic coupling or a hydrodynamic converter is arranged.

Eine andere bevorzugte Weiterbildung besteht darin, dass zwei Propeller enthalten sind, von denen einer als Druckpropeller und einer als Zugpropeller des Propulsionsantriebs angeordnet und ausgelegt ist.Another preferred development consists in that two propellers are contained, one of which is arranged and designed as a pressure propeller and one as a draft propeller of the propulsion drive.

Der erfindungsgemäße Propulsionsantrieb kann auch dergestalt sein, dass die Antriebsmotoreinrichtungen einen in dem Unterwassergehäuse angeordneten Motor enthalten, dem das Planetengetriebe nachgeschaltet ist, wobei weiter vorzugsweise der Motor ein Elektromotor ist, wie insbesondere ein Permasyn-, Asynchron-, Synchron-, HTS- oder HY-Elektromotor.The propulsion drive according to the invention can also be such that the drive motor devices include a motor arranged in the underwater housing, which is followed by the planetary gear, wherein more preferably the motor is an electric motor, in particular a Permasyn-, asynchronous, synchronous, HTS or HY -Elektromotor.

Weiterhin kann mit Vorzug vorgesehen sein, dass die Lagerung des Planetenträgers mit Propellerwelle im Unterwassergehäuse auch die Kräfte und Momente vom Propeller aufnimmt und ins Gehäuse weiterleitet.Furthermore, it may be provided with preference that the bearing of the planet carrier with propeller shaft in the underwater housing also absorbs the forces and moments from the propeller and forwards them into the housing.

Process and device features result analogously also from device or process descriptions.

Gleiche Bezugszeichen in den einzelnen Figuren und Abbildungen der Zeichnung bezeichnen gleiche oder ähnliche oder gleich oder ähnlich wirkende Komponenten. Anhand der Darstellungen in der Zeichnung werden auch solche Merkmale deutlich, die nicht mit Bezugszeichen versehen sind, unabhängig davon, ob solche Merkmale nachfolgend beschrieben sind oder nicht. Andererseits sind auch Merkmale, die in der vorliegenden Beschreibung enthalten, aber nicht in der Zeichnung sichtbar oder dargestellt sind, ohne weiteres für einen Fachmann verständlich.The same reference numerals in the individual figures and illustrations of the drawing designate the same or similar or the same or similar components. On the basis of the representations in the drawing, those features are also clear, which are not provided with reference numerals, regardless of whether such features are described below or not. On the other hand, features that are included in the present description but are not visible or illustrated in the drawing will be readily understood by those skilled in the art.

In der Fig. 1 ist schematisch in einem Längsschnitt ein erstes Ausführungsbeispiel eines Propulsionsantriebs P gezeigt. Dieser Propulsionsantrieb P enthält einen Kegelradsatz 1, eine Planetenträger/Propellerwelle 2, Planetenräder 3 (nur eines ist in der Fig. 1 sichtbar), ein Planetengetriebe 4 damit, einen Propeller 5, ein Unterwassergehäuse 6 und eine Propellerwellenlagerung 7.In the Fig. 1 is shown schematically in a longitudinal section a first embodiment of a Propulsionsantriebs P shown. This Propulsionsantrieb P includes a bevel gear 1, a planet carrier / propeller shaft 2, planet gears 3 (only one is in the Fig. 1 visible), a planetary gear 4 so that a propeller 5, an underwater housing 6 and a propeller shaft bearing. 7

Durch die Anordnung eines Planetengetriebes 4, welches dem Kegelradsatz 1 nachgeschaltet ist, wird erst vor dem Propeller 5 das Propellermoment zur Verfügung gestellt. Dies erlaubt einen kleinen Kegelradsatz 1 als bei herkömmlichen Bauarten ohne ein solches Planetengetriebe 4. Durch die Planetenbauart mit Lastverteilung auf 3 - 6 Planeten kann ein kleinerer Gehäusedurchmesser realisiert werden, wie insbesondere beispielsweise ca. 30 % vom Propellerdurchmesser. Durch den kleinen Gehäusedurchmesser, was in der Praxis einen kleineren Durchmesser der Birnenform des Unterwassergehäuses 6 bedeutet, wird die Propellerstrahlfläche weniger abgedeckt, was einen besseren Propellerwirkungsgrad ergibt. Dies gilt bei der Ausführung als Druckpropeller, wo das Unterwassergehäuse 6 vor dem Propeller 5 angeordnet ist, und auch bei einem Zugpropeller, wo der Propeller 5 vor dem Unterwassergehäuse sitzt.Due to the arrangement of a planetary gear 4, which is connected downstream of the bevel gear 1, the propeller torque is made available only before the propeller 5. This allows a small bevel gear set 1 than in conventional designs without such a planetary gear 4. The planetary design with load distribution on 3 - 6 planets, a smaller housing diameter can be realized, in particular, for example approx. 30% of the propeller diameter. Due to the small housing diameter, which in practice means a smaller diameter of the pear shape of the underwater housing 6, the propeller jet area is less covered, resulting in a better propeller efficiency. This applies to the version as a pressure propeller, where the underwater housing 6 is arranged in front of the propeller 5, and also in a tractor propeller, where the propeller 5 sits in front of the underwater housing.

Das Besondere an dieser Bauart ist, dass der Planetenträger ein Teil der Propellerwelle 2 ist und auch so im Unterwassergehäuse 6 gelagert wird.The special feature of this design is that the planet carrier is part of the propeller shaft 2 and is also stored in the underwater housing 6.

Durch diese Konstruktion kann die Untersetzung im "Unterwasser-Getriebe", die beim Kegelradsatz 1 bis ca. 4 ausgeführt wird, vergrößert werden. Untersetzungen bis ca. 10 sind möglich. So kann z.B. bei einer L-Version (Antriebskonzept mit vertikal aufgebautem Elektromotor) ein Elektromotor mit höherer Drehzahl zur Anwendung kommen (1200 - 1800 Upm). Der Elektromotor mit hoher Drehzahl hat kleinere Abmessungen und erlaubt so eine günstige Konstruktion.By this construction, the reduction in the "underwater transmission", which is performed at the bevel gear 1 to about 4, be increased. Reductions up to approx. 10 are possible. Thus, e.g. in the case of an L version (drive concept with vertical electric motor), a higher-speed electric motor is used (1200 - 1800 rpm). The high-speed electric motor has smaller dimensions and thus allows a favorable construction.

In der Fig. 2 ist schematisch in einem Längsschnitt ein zweites Ausführungsbeispiel eines Propulsionsantriebs P gezeigt. Dieser Propulsionsantrieb P enthält ein Unterwassergehäuse 11, einen Elektromotor 12, der stellvertretend für allgemein Antriebsmotoreinrichtungen steht, eine Zahnkupplung 13, ein Sonnenrad 14 und Planetenräder 15, von denen nur eines sichtbar ist, ein Hohlrad 16, eine Planetenträger/Propellerwelle 17, einen Propeller 18 und eine Propellerwellenlagerung 19.In the Fig. 2 is shown schematically in a longitudinal section a second embodiment of a Propulsionsantriebs P shown. This propulsion drive P includes an underwater housing 11, an electric motor 12, which is representative of generally drive motor devices, a gear coupling 13, a sun gear 14 and planet gears 15, of which only one is visible, a ring gear 16, a planet carrier / propeller shaft 17, a propeller 18th and a propeller shaft bearing 19.

Der im Zusammenhang mit der Fig. 1 erläuterten Ausführungsvariante der Anordnung des Planetengetriebes 4, mit dem Planetenträger als Teil der Propellerwelle, kann auch dem Elektromotor 12 in dem Unterwassergehäuse 11, das auch als Unterwassergondel bezeichnet werden kann, nachgeschaltet werden. Mit dieser Anordnung kann ein Elektromotor 12 mit höherer Drehzahl verwendet werden (4-5 fache der Propellerdrehzahl), der einen wesentlich geringeren Bauraum benötigt. Durch diese Bauart werden ferner die Kräfte und Momente aus dem Propeller, sowie die Untersetzung auf die Propellerdrehzahl, völlig vom Elektromotor 12 abgekoppelt.The one related to the Fig. 1 explained embodiment of the arrangement of the planetary gear 4, with the planet carrier as part of the propeller shaft, and the electric motor 12 in the underwater housing 11, which can also be referred to as underwater nacelle, be followed. With this arrangement, an electric motor 12 with higher speed be used (4-5 times the propeller speed), which requires a much smaller space. By this design further, the forces and moments from the propeller, and the reduction to the propeller speed, completely decoupled from the electric motor 12.

Als Antriebsmotor sind die unterschiedlichsten Elektromotoren, wie z.B. Permasyn-, Asynchron-, Synchron-, etc. und auch HTS- und HY-Motoren möglich.As a drive motor, the most diverse electric motors, such. Permasyn-, asynchronous, synchronous, etc. and also HTS and HY motors possible.

Wie schon für das Ausführungsbeispiel gemäß der Fig. 1 gilt, so liegt das Besondere in der Bauart der "Propellerwelle", die den Planetenträger integriert und im Unterwassergehäuse gelagert ist. Alle Kräfte und Momente vom Propeller 18 und Antrieb (Antriebsmotor/Elektromotor 12 oder Kegelradgetriebe/Kegelradsatz 1) sowie der Propellerschub werden über die Lagerung der Propellerwelle 2 bzw. 17 mit integriertem Planetenträger ins Unterwassergehäuse 6 bzw. 11 geleitet.As for the embodiment according to the Fig. 1 applies, so is the special in the design of the "propeller shaft", which integrates the planet carrier and stored in the underwater housing. All forces and moments from the propeller 18 and drive (drive motor / electric motor 12 or bevel gear / bevel gear 1) and the propeller thrust are passed through the bearing of the propeller shaft 2 or 17 with integrated planet carrier in the underwater housing 6 and 11 respectively.

Der Propulsionsantrieb kann mit Festpropeller und auch mit Verstellpropeller ausgeführt werden. Der Antrieb kann als Zugpropeller (der Propeller ist in Fahrtrichtung vor dem Unterwassergehäuse angeordnet) und/oder als Druckpropeller (der Propeller ist in Fahrtrichtung hinter dem Unterwassergehäuse angeordnet) ausgeführt werden.The propulsion drive can be carried out with fixed propellers and also with variable pitch propellers. The drive can be designed as a draft propeller (the propeller is positioned in front of the underwater housing in the direction of travel) and / or as a pressure propeller (the propeller is located behind the underwater housing in the direction of travel).
