Description

Rudder trunk of water vehicle, method of manufacturing water vehicle having rudder trunk and rudder trunk

The present invention relates to a rudder trunk for a ship comprising a rudder stock tube, a receiving shaft and a holder for retaining the rudder stock tube on the receiving shaft, wherein the rudder stock tube comprises a receiving shaft An intermediate space is provided between the rudder stock tube and the receiving shaft in a state of being disposed therein. In addition, the present invention relates to a method for manufacturing a rudder trunk and a ship including a rudder trunk, a rudder stock tube for a rudder trunk, a receiving shaft for a rudder trunk, and a kit for a rudder trunk.

In the prior art, so-called rudder trunks are used to store large rudders, for example on merchant ships or container ships. The rudder trunk of the steering gear is used to mount the rudder stock and transmit the rudder force to the ship. When deployed on a ship, the rudder trunk includes a receiving shaft disposed in the hull and a rudder stock tube disposed in the receiving shaft. The rudder stock tube may be fixed by welding or gluing to the receiving shaft. The rudder stock tube is inserted and fixed on the receiving shaft and supported by axial and radial bearings.

Applicant's EP 2583892 A1 discloses a glued rudder trunk, wherein a rudder stock tube is placed on a receiving shaft, intermediately between a first part of the coke tube and the wall of the receiving shaft. A space is provided, the intermediate space being at least partially filled with connecting means, the connecting means being a means for gluing.

In the prior art, installing the rudder stock tube to the receiving shaft of the hull is done overhead. The stern of the ship in which the rudder trunk is arranged is generally manufactured separately during the construction of the ship by being rotated 180° up and down, i.e. with the upper deck facing down. Thus, the rudder stock tube of the rudder trunk is inserted into the stern from above. The stern part is converted into a vertical position, meaning that the upper deck is facing up, only after the arrangement of the rudder trunk is completely completed, and is connected to the ship's hull, where the hull includes the propeller and the stern tube. Thus, the alignment of the rudder stock tube to the receiving shaft is up to now independent of the actual propeller shaft or stern tube.

However, for hydraulic efficiency, it is advantageous if the rudder trunk or the rudder stock tube of the rudder trunk and the rudder are aligned or adjusted to the ship's actual stern tube or actual propeller shaft. In known rudder stock tube installation methods that do not reference an actual propeller shaft or stern tube, this adjustment or alignment can only be performed indirectly and at great cost.

It is an object of the present invention that the stern part is already provided in such a way that the rudder trunk, in particular the rudder stock tube, can be aligned or adjusted with respect to the actual propeller axis or the actual stern tube in order to be easy to manufacture, to have low manufacturing costs and to improve the hydraulic efficiency. To provide a ship's rudder trunk that can be mounted on the hull when connected to the hull.

In addition, an object of the present invention is to provide a ship including a rudder trunk, a rudder stock tube for a rudder trunk, a receiving shaft for a rudder trunk, and a kit for a rudder trunk, and a method for manufacturing a rudder trunk capable of achieving the above-mentioned advantages. is in providing

To achieve the object of the present invention, a rudder trunk for a ship comprising a rudder stock tube, a receiving shaft and a holder for holding the rudder stock tube on the receiving shaft is proposed.

For this purpose, the holder element is inserted between the limbs of the U-profile body and placed on the base section of the U-profile body. In the above embodiment, twisting of the rudder stock tube at the receiving shaft is also prevented or may be limited. The rotary brake is provided through the interaction of the holder element and the complementary holder piece.

In principle, it is also possible that the holder element on the rudder stock tube is formed as a U-shaped profile body, and the complementary holder piece is formed as a pin, bolt, lug, plate or rod on the receiving shaft. In both options, only the orientation of the U-profile body has to be considered.

If the U-profile body is placed as a complementary holder piece on the receiving shaft, the rim of the U-profile body on the receiving shaft should be oriented vertically upward, thus forming a pin, bolt, protrusion, plate or rod. The holder element of the rudder stock tube can be inserted from above into the U-profile body.

On the other hand, if the U-profile body is placed as a holder element on the rudder stock tube, the rim of the U-profile body in the rudder stock tube must be aligned vertically downward, so that the U-profile body can It can be placed from above on the complementary holder piece of the receiving shaft formed as a projection, plate or rod. "Vertical", "above" and "below" are relative to the condition in which the rudder stock tube is in the receiving shaft where it is placed on the vessel.

However, in addition to these preferred embodiments, other embodiments of the holder element and the complementary holder piece are also possible.

Thus, either the holder element or the complementary holder piece may be a threaded bolt. In this case, the corresponding complementary holder piece or the corresponding holder element is formed as a receptacle, in particular a bore hole, preferably a bore hole with an internal thread. Threaded bolts can be screwed into the internal threads of the holder or bore hole. By determining the threading depth, the rudder stock tube can be aligned or adjusted at the receiving shaft, in particular radially of the receiving shaft.

Another preferred possibility is that the holder element is a recess, in particular a circumferential recess, preferably a groove around the rudder stock tube. The complementary holder piece may be formed of a clamping element, in particular a clamping ring, more preferably also a clamping ring arranged in a groove of the inner wall of the receiving shaft. If the rudder stock tube is inserted into the receiving shaft, the clamping element formed by the complementary holder piece can fit both in the recess on the rudder stock tube and in the recess, in particular the groove, of the receiving shaft, so that the rudder stock tube is placed on the receiving shaft. Maintaining a shape fit and/or a press fit of the is ensured or advantageous. However, in principle, a complementary holder piece designed as a clamping element and a corresponding holder element, insofar as the clamping element and the corresponding holder element together result in a press-fit and/or form-fit clamping between the rudder stock tube and the receiving shaft Rings and recesses may be designed differently.

In another possibility, the holder element and/or the complementary holder piece is threaded, wherein the rudder stock tube is provided with an external thread and the receiving shaft is provided with an internal thread. In this case, the rudder stock tube can be screwed into the receiving shaft, and the holder element formed with internal and external threads and complementary holder pieces provide a form-fit and press-fit connection. With a suitable embodiment of the threads, in particular the thread distribution, it is possible to move the rudder stock tube in the receiving shaft in such a way that the rudder stock tube can be aligned with the actual propeller axis and the actual stern tube in the vessel. After alignment, the rudder stock tube can be secured in the receiving shaft using a linkage.

More advantageously, the at least one holder element and the at least one complementary holder piece protrude into the intermediate space between the rudder stock tube and the receiving shaft, wherein the at least one complementary holder piece and/or the at least one holder element are arranged inclined in the axial direction of the rudder stock tube or receiving shaft, in the respective radial directions with respect to the rudder stock tube or receiving shaft.

With the receiving shaft and rudder stock tube arranged in the hull, the holder element and/or complementary holder piece is preferably aligned with a slight downward and/or upward tilt. Due to this slight inclination in the axial direction, a particularly advantageous alignment and adjustment of the rudder stock tube on the receiving shaft can be ensured. If, for example, two U-profile bodies are placed opposite each other in the receiving shaft as complementary holder pieces, the rims of the U-profile bodies are directed upwards, and the radial U-profile bodies into the interior space of the receiving shaft The path of has a slight slope downward, whereas if two bolts are placed as holder elements on the outer wall of the rudder stock tube, the bolts from above form a shape and press fit connection or holder to the U-profile body. can be inserted into Now if the rudder stock tube is aligned, i.e. in particular if the central axis of the rudder stock tube is aligned with the central axis of the receiving shaft, this can be done by moving the rudder stock tube approximately radially on the receiving shaft. At this time, one of the bolts is guided slightly downward along the U-profile body inclined slightly downward, and the other bolt is guided slightly upward to the second U-profile body. Thereby, the central axis of the rudder stock tube is inclined with respect to the central axis of the receiving shaft. A corresponding effect occurs for at least three or at least four or exactly four holder elements or complementary holder pieces.

More advantageously, the at least two holder elements may be disposed along the outer periphery of the rudder stock tube, preferably evenly, and/or the at least two complementary holder pieces may be disposed along the inner periphery of the receiving shaft, preferably It can be evenly spaced.

Holders provided in this manner are similar in bayonet lock function.

When inserting the rudder stock tube into the receiving shaft from below, the rudder stock tube is first aligned so that the holder element can be guided past the complementary holder piece. The rudder stock tube can be rotated as soon as the holder element is placed over the complementary holder piece so that the holder element is aligned flush with the receiving shaft or rudder stock tube axial direction to which the complementary holder piece is aligned. Next, the rudder stock tube can be moved axially downward, the holder element collapsing into a form fit and/or press fit connection with the complementary holder piece, retaining the rudder stock tube on the receiving shaft.

Advantageously, if the intermediate space is not filled, the rudder stock tube is adjusted to the receiving shaft, in the state where the rudder stock tube is arranged on the receiving shaft, in particular on the vessel of the rudder trunk comprising the rudder trunk and the receiving shaft; can be specifically aligned.

Thus, the adjustment of the rudder stock tube arranged on the receiving shaft can be carried out with particular advantage as it is placed on the vessel, ie in contrast to a real propeller or a real stern tube. Adjustment is preferably performed when the intermediate space is not yet filled with the connecting means. However, this can also be done when the intermediate space is preferably partially filled with the connecting means. If the connecting means is cast plastic, alignment or adjustment may be performed while the cast plastic is curing.

Preferably, for alignment and adjustment, the rudder stock tube is movable relative to the radial direction of the receiving shaft on the inner surface of the receiving shaft.

Preferably, an intermediate space between the outer wall of the rudder stock tube and the inner wall of the receiving shaft expands or decreases at least in the axial direction of the rudder stock tube. In other words, the gap width of the intermediate space between the outer wall of the rudder stock tube and the inner wall of the receiving shaft increases or decreases in at least some areas in the axial direction of the rudder stock tube. Particularly preferably, the gap width of the intermediate space is directed upwards when viewed in the axial direction of the rudder stock tube, ie in the direction of the ship body, in particular the hull, with the receiving shaft or rudder trunk arranged on the ship, in particular the ship, the rudder stock tube It increases at least locally between the outer wall of the and the inner wall of the receiving shaft.

An increase in the gap width results in an at least locally increased inner diameter of the receiving shaft with the receiving shaft disposed on the ship in the direction of the hull, and/or a rudder stock tube with the rudder stock tube disposed on the ship in the direction of the hull. The outer diameter of can be made by at least partially reducing. Particularly preferably, the wall thickness of the rudder stock tube decreases when viewed in the axial direction of the rudder stock tube, the inner diameter of the rudder stock tube remains constant in the axial direction and the outer diameter decreases.

With the rudder stock tube disposed on the receiving shaft, the rudder stock tube is disposed above the clamping height of the receiving shaft. The clamping height is preferably formed between the outer face or lower end of the receiving shaft and the upper region, in particular the upper end, of the rudder stock tube. Preferably, the gap width increases at least partially along the path of the clamping height. In this case, particularly advantageously, the lower region of the clamping height can have a constant gap width. To increase the gap width from region to region, the gap width increases over regions with a constant gap width.

Furthermore, the gap width in the upper range of the clamping height viewed in the axial direction can again decrease. A reduction of the gap width in the upper region of the clamping height can be caused by a complementary holder piece and/or holder element of the holder protruding into the intermediate space. The reduction of the gap width in the upper region of the clamping height may also be effected by means of a flange on the inner wall of the receiving shaft, in particular a circumferential flange or an outer wall of the rudder stock tube in the upper region.

However, in principle, the gap width of the intermediate space is in the axial direction of the rudder trunk when viewed from below, i.e. in the direction away from the ship body, in particular the hull, in the ship, in particular with the receiving shaft or rudder trunk arranged on the ship, the rudder stock It increases at least locally between the outer wall of the tube and the inner wall of the receiving shaft.

More advantageously, the intermediate space can be filled or filled, at least in some areas, with a connecting means, preferably a cast plastic, in particular a cast resin.

The intermediate space is preferably at least partially filled with a connecting means, in particular cast plastic, only after alignment and adjustment of the rudder stock tube in the receiving shaft. As soon as a rigid connection of the rudder stock tube and the receiving shaft is established by the connecting means, for example as soon as the cast plastic hardens, a rudder stock tube fixed and aligned or adjusted to the receiving shaft is obtained, whereby a particularly high hydraulic power is obtained. efficiency is provided. In addition, as the holder element and the complementary holder piece are preferably still left in the intermediate space, damage to the connecting means, for example slipping of the rudder stock tube, is prevented even if the cast plastic has come off.

Particularly preferably, the intermediate space is filled with the connecting means only in the lower region of the clamping height with a constant gap width. Additionally or alternatively, the intermediate space can be filled with the connecting means only in the upper region of the clamping height, in particular only in the region of the holder element and/or the complementary holder piece and/or the flange. Particularly preferably, the intermediate space in the region where the gap width is widened is not filled with the connecting means.

More advantageously, a sealing element, in particular a sealing sleeve, may be provided, the sealing element being attached to the outer surface of the rudder trunk, so that when the intermediate space is filled, the sealing element prevents leakage of the connecting means to the outer surface. This can be prevented and preferably the sealing element can be removed, in particular after the intermediate space has been filled.

With the rudder trunk arranged in the region of the ship's hull, preferably surrounding the outer opening of the receiving shaft, the outer surface of the rudder trunk corresponds to the outer surface of the ship's hull. At the location of the ship's receiving shaft, the rudder stock tube can be inserted into the receiving shaft from below. Next, a sealing element, in particular a sealing sleeve, is attached to the outer surface of the ship's hull and thus the outer surface of the rudder trunk, and seals the intermediate space between the rudder stock tube and the receiving shaft from below. After attaching the sealing element, the intermediate space between the rudder stock tube and the receiving shaft can be filled with a connecting means, in particular of cast plastic, and the sealing element allows the connecting means to pass from the intermediate space, in particular downwards, to the outer surface of the rudder trunk or It prevents them from escaping to the outer surface of the hull. After filling the intermediate space with the connecting means, the sealing element can be left on the outer surface of the rudder trunk or on the hull. However, it is also possible that the sealing element is removed after the intermediate space has been filled with the connecting means. If the sealing element is left on the outer surface of the rudder trunk or on the hull, additional protection is provided against leakage of the connecting means, in particular of cast plastic. On the other hand, if the sealing element is removed, it can be reused.

More advantageously, the sealing element is designed as a single piece, in particular consisting of one part or a plurality of parts.

The multi-part design of the sealing element enables a particularly simple attachment of the sealing element on the outer surface of the rudder trunk or the outer surface of the hull.

An additional advantage is provided if the sealing element has at least one breakthrough, in particular an opening or passage, through which the connecting means can be introduced, in particular into an intermediate space.

If the sealing element is located on the outer surface of the hull or the outer surface of the trunk in the region of the rudder trunk, the connecting means can be introduced from the outer surface of the vessel into the intermediate space through a through hole, in particular through an opening or passage. This provides a particularly easy way to fill in the intervening space.

The opening can be closed to prevent leakage of the connecting means, in particular of the cast plastic, after the intermediate space is filled. Also, a hose for introducing the connecting means may pass through the opening. As a result, the generation of bubbles in the connecting means, in particular in the cast plastic, can be prevented.

More advantageously, the coupling, in particular cast plastic, can be liquefied, preferably via heat input, so that the rudder stock tube can be removed from the receiving shaft after liquefaction of the coupling.

Replacing the rudder stock tube is simplified if the linkage, especially the cast plastic, can be liquefied through heat input. Thus, if replacement of the rudder stock tube is absolutely necessary, the connecting means can be liquefied through heat input. The rudder stock tube can then be removed from the receiving shaft on the hull. For this purpose, in a preferred embodiment, after liquefaction of the connecting means, the rudder stock tube must be erected vertically, so that the rudder stock tube moves up the receiving shaft. Next, the rudder stock tube is rotated so that the already flush aligned holder element and complementary holder piece can be twisted towards each other. Next, the rudder stock tube can be led axially downward from the receiving shaft, and the holder element is guided past the complementary holder piece. A new rudder stock tube can then be inserted.

More advantageously, a heating element, in particular a heating wire, is arranged in the intermediate space, preferably incorporated in the connecting means.

By providing a heating element, in particular a heating wire, replacement of the rudder stock tube is further simplified. Via the heating element, in particular the heating wire, thermal energy can be transferred uniformly to the connecting means for replacement in a uniformly liquefied manner.

A rudder trunk or rudder stock tube or accommodating shaft or groove or bore hole for a sensor attached to the rudder shaft may be provided in the rudder stock tube or accommodating shaft to guide a suitable signal carrier, such as a cable. Preferably, the signal carrier can be guided into an intermediate space between the rudder stock tube and the receiving shaft, more advantageously coming out at the minimum load point of the receiving shaft or the rudder stock tube.

Preferably, an adjacent holder element, in particular a bolt or rod, and a complementary holder piece, in particular a profile body or a U-profile body, inhibit or prevent rotation of the rudder stock tube when a rotational or torsional force is applied to the rudder stock tube. .

The holder element and the complementary holder piece are thus preferably rotary brakes. This improves the transmission of rudder stock forces to the hull. In particular, if the complementary holder piece is formed from a U-profile body and the holder element is formed from a bolt, pin, protrusion, rod or plate disposed between the rims of the complementary holder piece formed from the U-profile body, at the receiving shaft Twisting of the rudder stock tube is prevented. However, a slight twist may be tolerated. This can be tolerated when the distance between the rims of the U-profile body is greater than the width of the holder element arranged between the rims. Due to the low allowable rotation, manufacturing tolerances can be compensated for when aligning the rudder stock tube to the receiving shaft.

1 shows a rudder trunk 100 comprising a rudder stock tube 10 and a receiving shaft 11 . The rudder trunk 100 is disposed on the hull 12 of the ship 13. The hull 12 includes an outer face 14 . The rudder stock tube 10 is formed of a hollow tube 15 and is inserted into the receiving shaft 11 from below in a vertical direction on the outer surface 14 of the hull 12. With the rudder stock tube 10 disposed on the receiving shaft 11, an intermediate space 19 is formed between the outer wall 17 of the rudder stock tube 10 and the inner wall 18 of the receiving shaft 11. do. The rudder trunk 100 includes a holder 20 for holding the rudder stock tube 10 within the receiving shaft 11. The holder 20 includes a holder element 21 attached to the outer wall 17 of the rudder stock tube 10 by means of material bonding, shape fitting, or press fitting. The holder 20 also includes a complementary holder piece 22 disposed on the inner wall 18 of the receiving shaft 11 in a form-fitting, material-bonding or press-fitting manner. Each complementary holder piece 22 projects radially 23 from the inner wall 18 of the receiving shaft 11 into the intermediate space 19 . Likewise, each holder element 21 projects radially 23 from the outer wall 17 of the rudder stock tube 10 into the intermediate space 19 . In addition, in the intermediate space 19 there is a connecting means 24 formed of cast plastic 25 and ensuring a rigid fixation of the rudder stock tube 10 to the receiving shaft 11 . Additionally, the rudder stock tube (10) extends in an axial direction (26).

A first embodiment of the holder 20 is shown in FIGS. 2a and 2b.

Figure 2a shows the rudder stock tube 10 and the receiving shaft 11 in the axial direction 26 opposite. Figure 2b shows a complementary holder piece 22 disposed on the inner wall 18 of the receiving shaft 11 and disposed on the outer wall 17 of the rudder stock tube 10, cut along the line A-A in Figure 2a. The holder element 21 is shown.

The rudder stock tube 10 includes four holder elements 21a to 21d protruding from the outer wall 17 of the rudder stock tube 10 into the intermediate space 19 . On the inner wall 18 of the receiving shaft 11 are arranged four complementary holder pieces 22a to 22d which also protrude into the intermediate space 19 . Holder elements 21a to 21d and complementary holder pieces 22a to 22d are equally spaced along the outer periphery of the rudder stock tube 10 or along the inner periphery of the receiving shaft 11 . As can be seen in FIG. 2b , the complementary holder pieces 22 or 22a to 22d are formed from a profile body 29 , in particular a U-profile body 28 . The U-profile body 28 includes a rim 30 and a base section 31. The holder element 21 or 21a to 21d is formed of a rod 32 and is arranged on the base section 31 of a complementary holder piece 22 or 22a to 22d formed of a U-profile body 28 . By placing the rod 32 on the base section 31 of the U-profile body 28, movement of the rudder stock tube 10 down the axial direction 26 is prevented or inhibited. The rim 30 of the U-profile body 28 also serves as a rotary brake 33. Thus, the rudder stock tube 10 in the arrangement shown in FIGS. 2a and 2b has a receiving shaft ( 11) can only be slightly rotated. In Fig. 2a, the intermediate space 19 between the rudder stock tube 10 and the receiving shaft 11 is not filled. Accordingly, the rudder stock tube 10 can be aligned or adjusted within the receiving shaft 11 . For this purpose, the underlay element 34 shown in FIG. 2b may be provided. By placing the underlay element 34 between the rod 32 and the base section 31 of the U-profile body 28, the rudder stock tube 10 can be adjusted on the receiving shaft 11. 2c and 2d the possibility of adjusting the rudder stock tube 10 to the receiving shaft 11 is shown. Thus, as in Fig. 2c, the rudder stock tube 10 is arranged in such a way that the central axis 35 of the rudder stock tube 10 is laterally offset with respect to the central axis 36 of the receiving shaft 11, It can be moved laterally on the receiving shaft 11 . In Fig. 2d, by placing the underlay element 34 between the holder element 21 and the complementary holder piece 22, the central axis 35 of the rudder stock tube 10 and the central axis of the receiving shaft 11 ( 36) is shown in a very exaggerated way that the angle α between them can be adjusted. After alignment, the central space 19 can be filled with a connector 24 , in particular with cast plastic 25 . After the connecting means (24) is hardened, the rudder stock tube (10) is fixed in the receiving shaft (11).

For the manufacture of the rudder trunk according to FIGS. 1 to 2d , the rudder stock tube is inserted into the receiving shaft 11 in a vertical direction 16 (see FIG. 1 ) from the outer side 14 of the hull 12 . For this purpose, as shown in FIG. 3 , the rudder stock tube 10 has a receiving shaft in such a way that the holder elements 21a to 21d and the complementary holder pieces 22a to 22d are not aligned flush with each other. (11) is rotated in reverse. In this position, the rudder stock tube 10 moves until the holder elements 21a to 21d are positioned over the complementary holder pieces 22a to 22d until the holder elements 21a to 21d are placed over the complementary holder pieces 22a to 22d. ), it can be inserted into the receiving shaft 11 in the vertical direction 16. Next, as shown in FIG. 2A, the rudder stock tube 10 rotates around the central axis 35 of the rudder stock tube 10 having the holder elements 22a to 22d, thereby rotating the holder elements 21a to 21d. can be aligned to the same height. Next, the rudder stock tube 10 can be moved downwards in the axial direction 26 or against the vertical direction 16, and thus the holder elements 21a to 21d, in particular holder elements formed from rods 32 is arranged in a holder piece formed of complementary holder pieces 22a to 22d, in particular a U-profile body 28. By arranging the holder elements 21a to 21d on the complementary holder pieces 22a to 22d, a holder 20 is formed which prevents or inhibits movement of the rudder stock tube in the axial direction 26 within the receiving shaft 11. It becomes (see Figure 1). Next, the rudder stock tube 10 can be aligned, in particular on the propeller shaft or stern tube. Then, the connecting means 24 is filled in the intermediate space 19 to fix the rudder stock tube 10 to the receiving shaft.

Another embodiment of holder 20 is shown in FIG. 4 . Compared to the embodiment of FIGS. 1 and 2a , the embodiment according to FIG. 4 has the holder element 21 or 21a to 21d radially into the intermediate space 19 between the rudder stock tube 10 and the receiving shaft 11 . It differs only in that it is formed as a rod 32 projecting into 23 and additionally inclined upwards with respect to the axial direction 26 . This is done by moving the rudder stock tube 10 in the receiving shaft 11 in the radial direction 23, due to the inclination, the holder element 21 or 21a to 21d formed by the U-profile body 28 and the complementary holder piece ( 22 or 22a to 22d) results in additional movement relative to or in the axial direction 26 . As a result, the central axis 35 of the rudder stock tube 10 is aligned with the central axis 36 of the receiving shaft 11 .

Another embodiment of a holder 20 is shown in FIGS. 5A and 5B. 5a and 5b show a possible embodiment of a holder 20 using a clamping element. The holder element 21 of the rudder stock tube 10 is formed with a recess 37, in particular a groove 38. A recess (37) is formed circumferentially around the rudder stock tube (10). The complementary holder piece 22 is formed as a clamping element in the form of a clamping ring 39 and is formed in the receiving shaft 11 via a second groove 40 in the circumferential direction around the inner wall 18 of the receiving shaft 11 . Arranged in a positive-locking manner. The clamping ring 39 is not completely closed, but comprises a gap 41 which allows the clamping ring 39 to widen at one point, according to FIG. 5b . When inserting the rudder stock tube 10 into the receiving shaft 11, the clamping ring 39 is first widened, so that the rudder stock tube 10 can be guided through the clamping ring 39. As soon as the recess 37 or groove 38 of the rudder stock tube 10 is placed at the level of the clamping ring 39, the clamping ring 39 is relaxed, which, as shown in Fig. 5a, It fits into the recess (37) or groove (38) of the stock tube (10). This prevents the rudder stock tube 10 from moving in the axial direction 26 of the rudder stock tube 10 in the receiving shaft 11 . Instead of clamping rings 39 and grooves 38, other clamping elements and appropriately formed holder elements 21 also positively lock and/or non-positive lock clamps between the rudder stock tube 10 and the receiving shaft 11. It can be used as a complementary holder piece 22 forming a.

Also shown in FIG. 1 is a sealing element 42 arranged on the outer side 14 of the hull 12 . The sealing element 42 is designed as a sealing sleeve 43, and the connecting means 24, in particular the cast plastic 25, is introduced into the intermediate space 19 between the rudder stock tube 10 and the receiving shaft 11. It includes a through hole 44 that can be. After the connecting means 24 has hardened, the sealing sleeve 43 can be left on the outer surface 14 of the hull 12 . Alternatively, it is also possible that the sealing sleeve 43 is removed from the outer surface 14 of the hull 12.

6 and 7 show another rudder trunk 100 . The rudder trunk 100 includes a receiving shaft 11 disposed on the hull 12 of the vessel 13. The rudder stock tube 10 is arranged on the receiving shaft 11 in such a way that an intermediate space 19 is formed between the outer wall 17 of the rudder stock tube 10 and the inner wall 18 of the receiving shaft 11 . The rudder stock tube 10 is arranged along the clamping height 45 in the receiving shaft 11 . In the lower region 46 of the clamping height 45, the intermediate space 19 between the inner wall 18 of the receiving shaft 11 and the outer wall 17 of the rudder stock tube 10 has a constant gap width 47 have The exterior of the rudder trunk 10, above the lower region 46 of the clamping height 45, in the axial direction 26 as viewed from the vertical direction 16 of the rudder stock tube 10 or upwards of the hull 12 An intermediate region 48 is provided in which the gap width 47 between the wall 17 and the inner wall 18 of the receiving shaft 11 increases in the direction of the hull 12 . For an increase in gap width 47, the rudder stock tube 10 has a wall thickness 49 that decreases upwards. The holder element 21 is arranged on the outer surface of the rudder stock tube 10 in the upper region 50 of the clamping height 45 . A corresponding complementary holder piece 22 is placed on the inner wall 18 of the receiving shaft 11 . The gap width 47 is reduced in the upper region 50 of the clamping height 45 via the holder element 21 or the complementary holder piece 22 . A circumferential flange may be provided instead of the holder element 21 and/or the complementary holder piece 22 . A connecting means 24 , for example of cast plastic 25 , is arranged in the upper region in the region of the holder element 21 and the complementary holder piece 22 . Similarly, the connecting means 24 is provided in the lower region 46 of the gap width 47 . The intermediate region 48 of the clamping height 45 is between the upper region 50 and the lower region 46 of the clamping height 45, and the intermediate space 19 in the intermediate region 48 is the connecting means 24 ) is not filled.

In the perspective view of FIG. 7 , an increasing gap width between the outer wall 17 of the rudder stock tube 10 and the inner wall 18 of the receiving shaft 11 can be clearly seen. In addition, in the lower region 46 of the constant gap width 47 and in the upper region 50 in the region of the holder element 21 or the complementary holder piece 22, connecting means 24 formed of cast plastic 25 this is shown
