Definitions
- the application relates to a submarine with the in the preamble of claim 1
- Steering system is the rotor of the electric servomotor motion coupled with a rotatable part of a spindle drive, while the linearly movable part of the spindle drive is rigidly connected to a push rod of a linkage for controlling the movement of a rudder of the steering gear.
- Planetary Scroll Drive proposed as a spindle drive.
- this measure alone is not sufficient to reduce the noise caused by electrically operated steering gear to a level desirable at crawl speed of the submarine.
- the invention has the object to provide a submarine with at least one steering gear, which causes compared to the previously used in submarines rowing significantly lower sound emissions.
- the submarine according to the invention is preferably a military submarine.
- This submarine has at least one steering gear with a
- the linear drive is designed as an electrically operated linear drive and has an electric servomotor and a motion-coupled spindle drive.
- This spindle drive is optionally directly, but preferably via a linkage with an oar of the submarine in operative connection.
- the rudder can be any rudder, for example a rudder, a depth rudder or a combined side and aileron of the submarine.
- the linear drive is preferably arranged in the pressure hull of the submarine, but may also be arranged outside the pressure hull with appropriate pressure encapsulation. to
- Motion coupling of the servomotor with the spindle drive is preferably a spindle nut of the spindle drive rotatably connected to a motor shaft of the servomotor.
- the spindle of the spindle drive in this case forms a linearly movable part of the
- Spindle drive is also possible to connect the spindle of the spindle drive rotatably connected to the motor shaft of the servo motor, in which case the spindle nut of
- Spindle drive forms the linearly movable part of the linear drive.
- the basic idea of the invention is to elastically support the linear drive of the steering gear in a bearing device with respect to the boat structure, under which a part of the submarine standing in rigid connection with the pressure hull of the submarine is to be elastically supported, at least in the direction of movement of the linearly movable part of the linear drive. It is therefore provided according to the invention that the linear drive is not supported directly but via the elastically formed bearing device relative to the boat structure. Since the linearly movable part of the linear drive can be moved both back and forth, is under the direction of movement of the linearly movable member typically a first direction of movement and a second opposite thereto movement direction to understand. With the elastic mounting of the linear drive, the goal is pursued, the linear drive over here, at least during the creeping of the
- Submarines ie when driving in a lower speed range, acoustically decouple from the boat structure of the submarine, so that at best no structure-borne noise is transmitted from the linear drive to the boat structure and from there to the outside environment of the submarine.
- the storage device is typically this way designed that the required for controlling the rudder rudder force, which is comparatively low at creeping of the submarine, of the linearly movable part of the
- Linear drive can be transferred to the rudder.
- a rudder force generated by the linear drive inevitably leads in the storage device to a certain movement of the linear drive in the direction of movement of its linearly movable part.
- this may have, if larger rudder forces are required than at creeping, the result that these rudder forces can not be transferred to the rudder.
- d. H. also when driving in a higher speed range of the submarine, such as in the
- Linear drive to be transferred to the rudder is advantageously provided to form the storage device multi-stage, so that it has at least two storage stages, of which a first storage stage has a higher elasticity than a second storage stage.
- the first storage stage is used to transfer the rudder forces at slow speed of the submarine, the then higher elasticity ensures the acoustic decoupling of the linear drive of the boat structure and at the same time the transmission of relatively low rudder forces in this case.
- the second storage stage is to transfer the rudder forces during a trip of the
- Submarines provided in a higher speed range than at crawl ensures the power transmission from the linear drive from the rudder.
- the storage device has at least one and preferably a plurality of storage elements which form the first storage stage provided for acoustic decoupling of the linear drive of the boat structure at creeping and at least one and preferably has a plurality of storage elements, which compared to the first storage level forming storage elements a lower elasticity to allow in this way a transmission of the rudder forces at speeds of the submarine above the speed at creeping speed.
- the latter storage elements thus form the second storage level.
- the storage elements, which form the first storage level may differ from each other in terms of their dimensions from the storage elements forming the second storage level. So can the first storage level forming
- Elastomer elements formed. These are those elements which are formed in the simplest case entirely of an elastomer and preferably of rubber.
- elastomer elements in the context of the invention are to be understood as meaning elements which are multilayered, wherein layers of an elastomer and metallic layers are preferably arranged one above the other in the direction of movement of the linearly movable part of the linear drive in an alternating sequence.
- the linear drive is due to its elastic support at least in the direction of movement of its linearly movable part to a certain extent movable.
- at least one stop is expediently provided which the
- the submarine according to the invention has a plurality of such preferably metallic trained attacks, which is particularly space-saving within the
- the linear drive is surrounded on the outside by a rigidly connected to the boat structure drive housing, on which the bearing device is supported in the direction of movement of the linearly movable part of the linear drive.

- a plurality of elastomer elements as storage elements.
- at least one stop element is arranged in particular between adjacent storage elements.
- the storage device expediently has two mutually challenged in the direction of movement of the linearly movable part of the linear drive elastic bearing.

- a drive housing surrounding the outside of the linear drive it is furthermore advantageously provided that it adjoins the housing
- Motor housing connects a linearly movable part of the linear drive radially outer surrounding housing.
- This housing preferably forms part of a
- Anti-twist device for the linearly movable part of the linear drive.
- On the outer circumference of this housing is preferably a radially outwardly directed annular collar
- Drive housing formed contact surface is preferably formed by a sleeve with an end face formed annular collar, wherein the annular collar serves as a bearing surface.
