description

The invention relates to a submarine with the features specified in the preamble of claim 1.

In addition to hydraulic rudder systems, in which the piston of a piston-cylinder arrangement is coupled in motion with at least one rudder, in the case of submarines rudder systems with an electric servomotor also belong to the state of the art. Such a steering gear is described for example in DE 10 2010 015 665 AI. In this rudder system, the rotor of the electric servomotor is coupled for movement directly 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 rudder system. To the existing in military submarines

In DE 10 2010 015 665 AI, the use of a ripple force-free torque motor as a servomotor and a planetary roller drive as a spindle drive is proposed.

Against this technological background, the invention has for its object to provide a submarine with at least one steering gear, which causes significantly lower noise emissions compared to the previously used in submarines rowing machines.

This object is achieved by a submarine with the features given in claim 1. Advantageous developments of this submarine will be apparent from the dependent claims, which follow the description and the drawings. In this case, the features specified in the subclaims in each case but also in a suitable combination with each other, the inventive solution according to claim 1 further develop.

The submarine according to the invention, which may in particular be a military submarine, has at least one steering gear with a linear drive. The linear drive is coupled for movement via a linkage with at least one rudder arranged on the outside of the submarine. The rudder can in principle be any rudder, for example a rudder, a depth rudder or a combined side and aft rudder of the submarine. In principle, all drives can be used as a linear drive, which lead to a translational movement of a motion-coupled with the linear drive part. 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.

According to a translationally movable push rod of the linkage, which is guided in the preferred arrangement of the servomotor within the pressure hull through the Druckkörperwandung, not, as hitherto usual, directly rigidly connected to a translationally movable part of the linear drive, but connected via an elastomer coupling with this in the direction of movement , Here, an elastomer coupling is to be understood as meaning a coupling in which the connection of the push rod and the translationally movable part of the linear drive takes place via at least one elastomer element which is arranged in the connecting direction of the push rod and the translationally movable part of the linear drive. The elastomeric coupling is typically designed to sufficiently transmit the tensile and compressive forces exerted on the push rod by the translationally movable part of the linear drive while at the same time allowing certain movements of the push rod obliquely to the translationally movable part of the linear drive. This is advantageous with regard to the assembly of the rudder system, since the push rod can be connected to the translationally movable part of the linear drive even with a certain angular offset. However, the decisive advantage of the connection of the push rod with the translationally movable part of the linear drive is that the at least one elastomer element of the elastomer coupling forms a damping element which substantially prolongs the propagation of structure-borne noise from the linear drive to the push rod and from there to the outside of the submarine reduced, which is particularly essential in a military submarine.

Preferably, an electric servo motor and a motion-coupled spindle drive form the linear drive of the rudder system of the submarine according to the invention. Particularly advantageous as a servo motor, a synchronous torque motor and spindle drive a planetary roller used, which cause only small noise emissions per se, which are then at best completely, but at least largely absorbed by the at least one elastomeric element of the elastomeric coupling. As a translationally movable part of the linear drive formed by the electric servomotor and the spindle drive

Preferably, the spindle of the spindle drive, in which case the rotor of the servomotor is rotatably connected to the spindle nut of the spindle drive, but it should be noted that optionally also the spindle nut can form the translationally movable part of the linear drive, in which case the spindle rotatably with is connected to the rotor of the servomotor.

As usual with spindle drives, the translationally movable part of the spindle drive which is preferably used according to the invention is also prevented from rotating by means of an anti-twist device. According to another preferred embodiment of the invention forms the Elastomer coupling a part of this rotation for the translationally movable part of the spindle drive. Accordingly, at least a portion of the elastomeric coupling is formed and / or arranged such that it allows a translational movement of the elastomeric coupling with the push rod and the translationally movable part of the spindle drive, a rotational movement of the elastomer coupling and, concomitantly, a rotational movement of the translationally movable part of the spindle drive does not allow.

To form an anti-rotation device, the elastomer coupling preferably has a rotationally fixed manner to the translationally movable part of the spindle drive connected to the clutch housing, which is guided positively fixed in a linear guide transversely to the direction of movement of the axially movable part of the spindle drive. The linear guide is expediently aligned corresponding to the path of movement of the translationally movable part of the spindle drive. The translationally movable part of the spindle drive is preferably rigidly attached to the clutch housing, while the push rod is preferably coupled within the clutch housing via at least one and preferably via a plurality of elastomer elements with the translationally movable part of the spindle drive.

The clutch housing may optionally be mounted displaceably on rolling elements in the linear guide. Constructively simpler, however, is an embodiment in which the coupling housing is slidably mounted in the linear guide. Here, the materials of which the linear guide and the coupling housing are formed,

suitably chosen so that the frictional resistance between the linear guide and the clutch housing is minimized. Thus, the coupling housing may advantageously be formed of bronze and the linear guide made of steel.

In principle, only a simple guide rail can serve as a linear guide for the coupling housing, on which the coupling housing is fixed positively in the direction transverse to the direction of movement of the translationally movable part of the spindle drive. It proves to be more favorable if the linear guide forms a closed space in which at least the translationally movable part of the

Spindle drive is guided and is protected in this way from contamination and unwanted mechanical interference.

In this context, it is advantageously provided that the linear guide for the coupling housing is formed by a pipe connected to a housing of the servomotor with at least one guide rail formed therein. Preferably, this tube extends from the housing of the servomotor to a wall of the pressure hull of Submarines, where the connected to the translationally movable part of the spindle drive via the elastomer coupling push rod is passed through the Druckkörperwandung.

The guide rail formed in the tube expediently extends over the entire length of the tube. It may be formed as a hollow rail, which is incorporated in the inner wall of the tube and in which a formed on the coupling housing protrusion positively engages. Preferably, however, the guide rail is formed by a protruding into the interior of the tube projection. This allows a much lighter design of the tube, since this can be formed comparatively thin-walled, wherein formed on the inner wall of the tube a conveniently over the entire length of the tube extending strip-shaped projection

is that forms the at least one guide rail. Corresponding to this projection at least one groove-shaped recess is expediently formed on the coupling housing, which extends over the entire coupling housing in the direction of movement of the translationally movable part of the spindle drive.

According to a further advantageous embodiment, a radial extension is formed on one of the translationally movable part of the spindle drive facing end of the push rod, which at their in the axial direction of the push rod facing away from each other via at least one elastomeric element and preferably via

supports a plurality of elastomeric elements on the coupling housing. Preferably engages the end portion of the push rod on which the radial extension is formed, via an opening of the coupling housing in a region of the coupling housing, which is closed in the direction of the attached to the outside of the coupling housing translationally movable part of the spindle drive by a wall. The opening of the coupling housing is in this case closed by a lid, through which the push rod is passed. Here, in each case at least one, but preferably a plurality of elastomer elements are arranged in a space between the radial extension and the wall of the coupling housing and in a space between the radial extension and the cover of the coupling housing, between which the radial extension of the push rod is fixed positively.

In order to allow the smoothest possible guidance of the coupling housing in the tube, it is expedient to lubricate the contact area between the inner wall of the tube and the outside of the coupling housing. For this purpose, a leading through the pipe wall Schmiermittelzuführleitung is advantageously formed on the pipe, through which a lubricant in the intermediate space

between the inner wall of the tube and the outside of the coupling housing can be initiated. The invention is explained in more detail with reference to an embodiment shown in the drawing. In the drawing shows schematically simplified and in different scales:

1 is a front view of an arrangement of a linear drive of a steering gear of a

Submarines with a push rod connected to the linear drive,

FIG. 2 shows the arrangement according to FIG. 1 in a side view along the section line II - II in FIG.

1, and

3 is a sectional view along the section line III-III in Fig. 2nd

As is apparent in particular from FIG. 2, the drawing shows a linear drive 2, with which a push rod 4 is motion-coupled to a linkage otherwise not shown in the drawing for reasons of clarity. The linear drive 2 has an electric servomotor 6 in the form of a synchronous torque motor. Of the

exact structure of the synchronous torque motor is not shown in the drawing, since it is not relevant to the invention. However, the servomotor 6 essentially corresponds to a synchronous torque motor described in detail in DE 10 2012 220 920 B3. As with this synchronous torque motor and a rotor of the servomotor 6 is rotatably connected rotatably connected to a spindle nut 8 of a planetary roller drive. The rotor of the servomotor 6 is formed as a hollow cylinder. In the interior of the rotor engages guided by the spindle nut 8 and there with this motion-coupled planetary roller spindle 10 a. Upon actuation of the servomotor 6, the spindle nut 8 of the planetary roller drive rotates, whereby the planetary roller spindle 10 is set in a translational movement along a central axis A of the planetary roller spindle 10. In this respect, the planetary roller spindle 10 forms a translationally movable part of the planetary roller spindle drive.

At an arranged outside of the servomotor 6 end of the planetary roller spindle

10, this is connected via an elastomer coupling 12 with the push rod 4. The elastomer coupling 12 has a substantially hollow-cylindrical coupling housing 14, in which a wall 16 formed in the interior of the coupling housing 14

a chamber 18 which is open toward the servomotor 6 and a chamber 20 which faces away from it. The chamber 20 is closed by a cover 22 screwed to the front side of the clutch housing 14. At the servomotor 6 facing side of the wall, the planetary roller spindle 10 is formed on a formed at the end of the planetary roller spindle 10 radial extension 24 on the Clutch housing 14 of the elastomeric clutch 12 is rigidly fastened by means of a screw connection. The push rod 4 engages through an opening 30 formed on the cover 22 into the chamber 20 of the coupling housing 14. Here, the push rod 4 is aligned such that its central axis coincides with the central axis A of the planetary roller spindle 10.

At a the servomotor 6 facing the end of the push rod 4, a ring member 26 is placed on this and firmly connected to the push rod 4. In this way, the ring member 26 forms a radial extension of the push rod 4. The ring member 26 has on its the servomotor 6 facing the outside six evenly distributed over the circumference of the ring member 26 recesses. Also on the side remote from the servomotor 6 outside of the ring member 26 six evenly over the circumference of the ring member 26 distributed recesses are formed. Each of these recesses

serves to receive a cylindrically shaped elastomeric element 28. The elastomeric elements 28 are dimensioned so that the arranged on the servomotor 6 side of the ring member 26 arranged elastomeric elements 28 between the ring member 26 and formed on the clutch housing 14 wall 16, while the on the side facing away from the actuator 6 side of the ring member 26 disposed elastomeric elements 28 between the ring member 26 and the screwed onto the clutch housing 14 cover 22 are supported. In this way, the push rod 4 in the direction of movement of the planetary roller screw 10 is fixedly connected to the clutch housing 14 and concomitantly fixed to the planetary roller spindle 10, wherein the elastomeric elements 28 form damping elements which absorb as much as possible from the servo motor 6 and the motion-coupled planetary roller body emanating sound.

On a front side 32 of a housing 34 of the servomotor 6, on which the planetary roller spindle 10 is led out of the servomotor 6, a pipe 36 is flanged. The tube 36 forms a linear guide for the elastomer coupling 12, which is slidably mounted in the tube 36. On an inner wall 38 of the tube 36 six projections 40 are uniformly distributed over the inner circumference 20 formed. The projections 40 are formed strip-shaped elongated and extend over the entire length of the tube 36th

Corresponding to the projections 40 in the tube 36, six recesses 42 are formed on the peripheral side of the coupling housing 14 of the elastomer coupling 12, which extend over the entire length of the coupling housing 14. In these recesses 42 engage the formed on the inner wall 38 of the tube 36 projections 40 a. In this way, the elastomeric coupling 12 and the tube 36 form an anti-rotation device for the planetary roller spindle 10 fixedly connected to the coupling housing of the elastomer coupling 12. In approximately half the length of the tube 36, a lubricant supply line 44 is formed on this, over which a lubricant in the contact area between the inner wall 38 of the tube 36 and the peripheral side of the clutch housing 14 can be initiated.
