Description

Rudder propeller drive and Rudderpropellerantriebsverfahren

description

The present invention relates to a rudder propeller drive according to the preamble of claim 1 and a rudder propeller drive method therewith.

For example, From DE 200 21 466 Ul a rudder propeller drive with a drive motor is known, in particular as indicated in the preamble of claim 1. Also known in practice is the use of hydrodynamic couplings in connection with marine propulsion, i. installed in the drive train of a drive. However, the hydrodynamic coupling is an independent element with closed housing and its own fluid filling, such as preferably oil.

The present invention has and achieves the goal of designing a known rudder propeller drive in such a way that it is particularly inexpensive to manufacture and operate.

This object is achieved with a rudder propeller drive with a drive motor whose output shaft is operatively connected via a drive train to a propeller shaft of a propeller, the propeller shaft being housed in a rudder propeller housing attachable outside a hull, and the propeller on the propeller shaft outside Rudderpropellergehäuses is located, wherein for the propeller shaft and / or for these upstream areas of the drive train, a lubricating and / or cooling device is contained, wherein the drive train further comprises a hydrodynamic coupling or a hydrodynamic torque ment converter contains, which / is so combined with the lubricating and / or cooling device or integrated into the lubricating and / or cooling device that the hydrodynamic coupling or the hydrodynamic torque converter and the lubricating and / or cooling device use a common amount of operating fluid.

Thus, the operating fluid of the lubricating and / or cooling device and the operating fluid of the hydrodynamic coupling or the hydrodynamic torque converter can be realized with one and the same fluid supply in an advantageous manner.

An advantageous development consists in that the lubricating and / or cooling device contains the interior of the rudder propeller housing, wherein further preferably operating fluid is contained in the interior of the rudder propeller housing and / or the hydrodynamic coupling or the hydrodynamic torque converter is in fluid communication with the interior of the rudder propeller housing. The latter can advantageously be realized in that the hydrodynamic coupling or the hydrodynamic torque converter in the interior of the rudder propeller housing or in an extension of the interior of the rudder propeller housing is located within the hull. Such an extension is structurally referred to, for example, as a cone support tube or support cone.

Yet another preferred embodiment of the invention is that the hydrodynamic coupling or the hydrodynamic torque converter in such a way combined with the lubricating and / or cooling device or integrated into the lubricating and / or cooling device that the hydrodynamic coupling or the hydrodynamic torque converter provides for a promotion of the operating fluid in the lubrication and / or cooling device. It may also be advantageously provided that the hydrodynamic coupling contains a plurality of hydrodynamic coupling units or the hydrodynamic torque converter contains a plurality of hydrodynamic converter units. Alternatively or additionally, it can be provided that in addition an elastic coupling and / or a shift clutch is installed in the drive train.

Furthermore, the drive motor may be located within the hull with preference.

In a rudder propeller drive method according to the invention, it is provided that an output shaft of a drive motor is operatively connected to a propeller shaft of a propeller via a drive train, which propeller shaft is accommodated in a rudder propeller housing which is located outside a ship's hull, and which propeller is located on the propeller shaft outside the rudder propeller housing wherein the propeller shaft and / or these upstream portions of the drive train are lubricated and / or cooled with an operating fluid, the power train including a hydrodynamic clutch or a hydrodynamic torque converter comprising the same amount of operating fluid used for lubrication and / or or cooling the propeller shaft and / or these upstream portions of the drive train is supplied with operating fluid.

In a further development thereof, it may be advantageously provided that the lubricating and / or cooling device contains the interior of the rotor propeller housing, and that the hydrodynamic coupling or the hydrodynamic torque converter is in fluid communication with the interior of the rudder propeller housing, in particular operating fluid in the interior of the rudder propeller housing may be contained, wherein still more preferably the hydrodynamic coupling or the hydrodynamic torque converter in the interior of the rudder propeller housing or in an extension of the interior of the rudder propeller housing, such as a cone support tube or a support cone, lies within the hull.

With preference, it can also be provided that the hydrodynamic coupling or the hydrodynamic torque converter is combined with the lubricating and / or cooling device or integrated into the lubricating and / or cooling device, that the hydrodynamic coupling or the hydrodynamic torque converter for a promotion the operating fluid in the lubricating and / or cooling device provides.

According to the invention, according to individual embodiments, in particular a ship propulsion in the form of a rudder propeller, for example with an integrated vertically arranged drive motor and particularly advantageously with integrated into the interior of the Rudderpropellergehäuses, which is part of lubricating and cooling devices, or in an extension thereof in the ship's interior hydrodynamic coupling or integrated hydrodynamic torque converter. The integration of the hydrodynamic coupling or the hydrodynamic torque converter in the interior of the rudder propeller housing or an extension thereof provides the opportunity to build a compact drive system. By positioning the hydrodynamic coupling or the hydrodynamic torque converter see within the Betriebsfluidfüllung, in particular oil filling, the Rudderpropellergehäuses the lubricant and coolant of the drive train of the Rudderpropellers and the filling of the hydrodynamic coupling or the hydrodynamic torque converter can be realized with one and the same fluid. This makes it superfluous to seal the hydrodynamic coupling or the hydrodynamic torque converter to the environment, as is required in a conventionally arranged hydrodynamic coupling or a conventionally arranged hydrodynamic torque converter. In the case of the mentioned extension, it is structurally referred to, for example, as a cone support tube or support cone. Hydrodynamic couplings or hydrodynamic torque converters naturally have a conveying effect from the inside to the outside. This conveying effect can be used by the invention to realize the fluid exchange, in particular lubricant exchange, between the submarine part which is very well cooled by the surrounding fairway, such as seawater, and the upper part of the rudder propeller drive, which is not cooled or cooled. For this purpose, separate pumps are required in today's known constructions.

The hydrodynamic coupling or the hydrodynamic torque converter can also be designed as a so-called double clutch or as a double converter, resulting in twice the transmittable torque with the same coupling or transducer diameter. By using a hydrodynamic coupling with blades which are inclined in the tangential direction in the pump and turbine wheel of the hydrodynamic coupling, the torque in one direction of rotation can likewise be increased. This is preferably done in the pre-rotation direction, which provides for a propeller thrust forward. For the reverse direction, i. in a propeller thrust backwards, results from the inclination of the blades a smaller transmissible torque, which is needed only in limited operating situations of the rudder propeller drive.

Further advantages of the invention are:

Vibration-decoupling of drive and work machine in the drive train in a compact space,

excellent acoustic isolation of the drive motor from the mechanical structure (rudder propeller and ship), which allows a particularly quiet operation,

- Reduction of the starting torque of the drive motor, i.

Achieving a πtöglichst or particularly small starting torque of the drive motor, Lubrication / cooling of the rudder propeller and filling of the hydrodynamic coupling or of the hydrodynamic torque converter with only one fluid and thus reduction of the variety of operating fluids,

Utilization of the conveying effect of the hydrodynamic coupling or the hydrodynamic torque converter for circulating the lubricating / cooling agent or fluid and thus omitting a corresponding conveying device,

Elimination of seals and thus wearing parts on the coupling and thus considerable savings in maintenance and service, and

Protection of the rudder propeller against overload impacts by e.g. Grounding, foreign objects in the water, ice and the like.

Further preferred and / or advantageous embodiments of the invention will become apparent from the claims and their combinations as well as the entire present application documents.

The invention will now be described by way of example with reference to exemplary embodiments with reference to the drawing, in which

1 shows in a schematic longitudinal section a first embodiment of a Rudderpropellerantriebs,

2 shows a schematic longitudinal section of a second embodiment of a rudder propeller drive,

Fig. 3 shows in a schematic longitudinal section a third embodiment of a Rudderpropellerantriebs, and Fig. 4 shows in a schematic longitudinal section a fourth embodiment of a rudder propeller drive.

With reference to the embodiments and applications described below and illustrated in the drawings, the

Invention only exemplified in more detail, i. it is not limited to these embodiments and examples of application or to the combinations of features within these embodiments and applications. Process and device features arise analogously also from device or. Process descriptions.

Individual features that are indicated and / or illustrated in connection with a specific embodiment, are not limited to this embodiment or the combination with the other features of this embodiment, but may in the context of the technically possible, with any other variants, even if they are in are not treated separately.

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 illustrations in the drawing, those features are also clear that 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.

1 shows schematically in a longitudinal section a first embodiment of a rudder propeller drive R with a drive motor 1 and a rudder propeller housing G mounted on a hull 2. Shown is a rudder propeller drive R with a "simple" hydrodynamic coupling 3, ie an impeller 3a and a turbine wheel 3b. The cited in connection with the embodiments and The hydrodynamic coupling shown is only to be understood as an example, and in the context of the present invention instead of a hydrodynamic coupling, a hydrodynamic torque converter can also be used and achieve the same results and advantages. Whenever reference is made below to a hydrodynamic coupling, it will be readily apparent to one skilled in the art that a hydrodynamic torque converter can be or may be provided in each case technically adapted, without this being indicated again at each individual position. While in the conventional hydrodynamic clutch, the slip of the rotational speed is constant or is set by the amount of the operating fluid, the torque converter is set in the torque converter, but this is achieved not by changing the filling with operating fluid but by adjusting vanes.

The representation of a Rudderpropellerantriebs R with a propeller P in a nozzle D is only an example. The application with a vertically arranged drive motor 1, such as an electric motor, is to be understood by way of example. The hydrodynamic coupling 3 can just as well be used in an otherwise mechanically driven rudder propeller drive R, for example using e.g. a bevel gear in the drive train A, are used.

Further components of the are an oil-filled interior 4 of the rudder propeller housing G, a vertical axis 5 of a drive train A, a controllable about the vertical axis 5 Rudderpropeller- housing foot, a vertical shaft 7 of the drive train A, an underwater part 8 of the rudder propeller housing G with a transmission (not shown ), a propeller shaft 9, an azimuth adjusting drive 10 and a nozzle D.

In this embodiment of the rudder propeller drive R, the hydrodynamic coupling 3 is inserted inside the oil-filled rudder propeller housing G, which concretely provides an expansion - S -

tion E within the hull 2 has, in which extension E, the hydrodynamic coupling 3 is added. As a result, the oil, which can generally be referred to as lubricating and cooling fluid or operating fluid B, simultaneously constitutes the operating fluid B or medium for the hydrodynamic coupling 3 in the interior 4 of the rudder propeller housing G, since the interior 4 of the hydrodynamic clutch 3 Rudder propeller housing G in the interior 4 'of the extension E passes. More specifically, the hydrodynamic coupling 3 uses the same amount of operating fluid as a lubricating and / or cooling device

SK, which is essentially formed by the rudder propeller housing G with the supply of operating fluid B. Such an extension E is, for example, a structure such as a cone support tube or a support cone.

In Fig. 1, the pumping action of the hydrodynamic coupling 3 is also shown by arrows F. This pumping action is used in whole or in part to circulate the operating fluid B, such as oil, in the rudder propeller housing G, which is normally done with an additional impeller or external pump.

In principle, an arrangement of the hydrodynamic coupling 3 or an alternatively usable hydrodynamic torque converter on the propeller shaft 9 is possible.

Insofar as components and parts are designated in FIGS. 2 to 4, the same reference numerals have been used as in FIGS. 1 and 2. Described and explained are only more differences of the embodiments according to FIGS. 2 to 4 with respect to the embodiment of FIG. 1, to avoid mere repetition.

2, in a schematic longitudinal section analogous to FIG. 1, a rudder propeller drive R with a double hydrodynamic coupling 3, ie with two pump wheels 3a and two turbine wheels 3b, is shown as a further exemplary embodiment. posed. Equally well, however, a clutch with more than two pumping wheels 3a and two turbine wheels 3b is conceivable.

Yet another embodiment of a rudder propeller drive R is shown in a schematic longitudinal section analogous to FIGS. 1 and 2 in FIG. 3 with a hydrodynamic coupling 3 and with a free-running propeller P, i. without a nozzle D as in the first and second embodiments.

FIG. 4 illustrates in a schematic longitudinal section analogous to FIGS. 1 to 3 rudder propeller drive R with a hydrodynamic coupling 3 in a twin-propeller design, i. with two propellers P.

As has already been explained above, reference was made in the context of the description of practical examples to a hydrodynamic coupling, but this is only to be understood as an example. Instead of a hydrodynamic coupling and a hydrodynamic torque converter in the context of the invention can be used. Since a hydrodynamic torque converter is thus in principle also suitable for use in the present application, a person skilled in the art can easily provide devices and methods with a hydrodynamic torque converter instead of the necessary apparatus and method adaptations instead of the exemplary hydrodynamic coupling. without being inventive or departing from the scope of the present invention.

The invention is illustrated by way of example only and not by way of example in the description and the drawing, but includes all variations, modifications, substitutions and combinations that the skilled person the present documents, in particular in the context of the claim and the general representations in the introduction this description and the description of the and can combine with his expert knowledge and the state of the art. In particular, all individual features and design options of the invention and its embodiments can be combined.
