Description

TECHNICAL FIELD

[0001] The invention relates to a rudder stock for a ship, comprising a rudder stock tube, a receiving shaft and a holder for holding the rudder stock tube in the receiving shaft, wherein in the state in which the rudder stock tube is arranged in the receiving shaft, an intermediate space is provided between the rudder stock tube and the receiving shaft. Furthermore, the invention relates to a ship comprising a rudder stock, a rudder stock tube of the rudder stock, a receiving shaft of the rudder stock, a rudder stock kit and a method of manufacturing a rudder stock. BACKGROUND

[0002] For the storage of large rudders, for example in merchant ships or container ships, so-called rudder stocks are used in the prior art. The rudder stock of the rudder serves to mount the rudder stock shaft and to transfer the rudder force into the ship. In the arrangement on the ship, the rudder stock comprises a receiving shaft arranged in the hull and a rudder stock tube arranged in the receiving shaft. The rudder stock tube can be fixed by welding or by gluing it in the receiving shaft. The rudder stock shaft is inserted into the rudder stock tube fixed on the receiving shaft and is supported by axial and radial bearings.

[0003] From EP 2 583 892 A1 of the same applicant, a glued rudder stock is known, in which the rudder stock tube is arranged in the receiving shaft and in which an intermediate space is provided between a first portion of the rudder stock tube and a wall of the receiving shaft, wherein the intermediate space is at least partially filled with an adhesive, wherein the adhesive is a component for gluing.

[0004] In the prior art, the mounting of the rudder stock tube in the receiving shaft of the hull is carried out overhead. During the shipbuilding process, the stern part, in which the rudder stock is arranged, is usually manufactured separately and rotated 180° upside down, i.e. the upper deck is facing downwards. Thus, the rudder stock tube of the rudder stock is inserted from above into the stern part. Only after the rudder stock has been arranged and completely finished, the stern part is turned into an upright position, which means that the upper deck is facing upwards and connected to the hull of the ship, which comprises the propeller and the stern tube. Thus, until this moment, the alignment of the rudder stock tube in the receiving shaft is independent of the actual propeller axis or the actual stern tube.

[0005] However, for hydrodynamic efficiency, it is advantageous if the rudder stock or the rudder stock tube of the rudder stock, and thus the rudder, is aligned or adjusted to the actual propeller axis or the actual stern tube of the ship. In the known rudder stock mounting method, it is not possible to refer to the actual propeller axis or the stern tube, such an alignment or adjustment can only be carried out indirectly and expensively. SUMMARY

[0007] It is an object of the invention to provide a rudder stock for a ship, which is easy to manufacture and cost-effective and which can be mounted into the hull of the ship when the stern part has been connected to the hull in such a way that the rudder stock, 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 improve the hydrodynamic efficiency.

[0008] Furthermore, it is an object of the present application to provide a ship, a rudder stock, a rudder stock tube of the rudder stock, a receiving shaft of the rudder stock, a rudder stock assembly and a method of manufacturing a rudder stock, which achieve the above-mentioned advantages.

[0009] In order to solve the underlying object of the present application, a rudder stock for a ship is proposed, comprising a rudder stock tube, a receiving shaft and a holder for holding the rudder stock tube in the receiving shaft, wherein in a state in which the rudder stock tube is arranged in the receiving shaft, an intermediate space is provided between the rudder stock tube and the receiving shaft, wherein the holder comprises at least one holder element and at least one complementary holder workpiece, wherein the at least one holder element is arranged on the rudder stock tube, wherein the at least one complementary holder workpiece is arranged on the receiving shaft, and wherein the at least one holder element and / or the at least one complementary holder workpiece protrudes into the intermediate space in the state in which the rudder stock tube is arranged in the receiving shaft.

[0010] The rudder stock for a ship according to the present application comprises a rudder stock tube and a receiving shaft. The receiving shaft is intended to be mounted in the ship, in particular in the aft portion of the ship, or the receiving shaft is already located in the ship. In the receiving shaft, the rudder stock tube can be arranged to form a rudder stock, or the rudder stock tube is already arranged within the receiving shaft. Furthermore, the rudder stock shaft can be arranged in the rudder stock tube if the rudder stock tube is attached to the receiving shaft of the ship's hull.

[0011] In the state in which the rudder stock tube is arranged in the receiving shaft, an intermediate space is provided between the rudder stock tube and the receiving shaft, in particular between the outer wall of the rudder stock tube and the inner wall of the receiving shaft. The entire intermediate space is preferably formed between the outer wall of the rudder stock tube and the inner wall of the receiving shaft. The at least one holder element arranged on the rudder stock tube and / or the at least one complementary holder workpiece arranged on the receiving shaft protrudes into the intermediate space. The holder element and the complementary holder workpiece form a holder for holding the rudder stock tube within the receiving shaft.

[0012] By holding the rudder stock tube in the receiving shaft with the holder consisting of the at least one holder element and the at least one complementary holder workpiece, the rudder stock tube can be inserted into the receiving shaft which is already mounted on the hull or is to be mounted on the hull, in particular the aft portion of the hull, if the aft portion is already connected to the hull, i.e. when the upper deck of the ship, in particular the upper deck of the aft portion, is facing upwards, while the keel of the hull is facing downwards, whereas in the prior art the mounting of the rudder stock in the receiving shaft of the hull is carried out overhead, that is to say when the aft portion of the ship, in which the rudder stock is arranged, is rotated 180° upside down, i.e. with the upper deck facing downwards.

[0013] In contrast to the mounting methods known from the prior art, the rudder stock tube of the rudder stock according to the application can be introduced into the receiving shaft from below and held in the receiving shaft. In particular, since the stern portion is already connected to the hull when the rudder stock is inserted into the receiving shaft from below, the rudder stock tube held by the holder can be aligned with the actual propeller axis or the actual stern tube of the ship.

[0014] The hydrodynamic efficiency can thus be improved in relation to the rudder stocks known from the prior art.

[0015] The protruding configuration of the at least one holder element and / or the at least one complementary holder workpiece into the intermediate space, in the state in which the rudder stock tube is arranged in the receiving shaft, provides a space-saving embodiment of the holder for holding the rudder stock tube within the receiving shaft, since no other elements of the holder have to be arranged outside the receiving shaft.

[0016] However, insofar as applicable, in order to align the rudder stock tube in the receiving shaft inside and / or outside the receiving shaft, an alignment aid can be provided with which the rudder stock tube can be held in an aligned position for aligning and subsequently fixing the rudder stock tube. However, the alignment aid is preferably removed after the alignment and fixing.

[0017] After aligning or adjusting the rudder stock tube in the receiving shaft to the actual propeller axis or the actual stern tube, the intermediate space can be filled with adhesive, preferably in sections, in order to fix the rudder stock tube in the receiving shaft.

[0018] A further advantage of the rudder according to the application is that, after connecting or fixing the rudder stock tube, the holder remains in the rudder and forces can also be transferred through the holder. For example, in the event of adhesive failure, protection against sagging or sliding of the rudder stock tube can be provided.

[0019] Preferably, the at least one holder element and the at least one complementary holder workpiece can be arranged in a form- and / or force-fitting manner, such that, in the state in which the rudder stock tube is arranged in the receiving shaft, in particular when the rudder comprising the rudder stock tube and the receiving shaft is arranged on the ship, movement of the rudder stock tube in the receiving shaft in the axial direction of the rudder stock tube is impeded or prevented.

[0020] By means of the form-fit and / or force-fit arrangement of the complementary retainer workpiece and the retainer element, in particular when the rudder stock arrangement comprising the rudder stock tube and the receiving shaft is in a state on the ship, the rudder stock tube can be held in a mounted position in the receiving shaft with the keel of the ship oriented downwards. In this case, the form-fit and / or force-fit arrangement of the retainer element and the complementary retainer workpiece impedes or prevents the rudder stock tube from moving in the axial direction of the rudder stock tube; in particular, the rudder stock tube is prevented from moving downwards out of the receiving shaft. In other words, the rudder stock tube in the receiving shaft cannot slide in its axial direction, in particular not downwards in the axial direction. This allows the adjustment of the rudder stock tube relative to the actual propeller axis or skeg of the ship before the rudder stock tube is fixed in the receiving shaft.

[0021] It is furthermore advantageous if at least two, preferably at least three, more preferably at least four, particularly preferably exactly four retainer elements and / or at least two, preferably at least three, more preferably at least four, particularly preferably exactly four complementary retainer workpieces are provided.

[0022] If at least two retainer elements or at least two complementary retainer workpieces are provided, they can preferably be arranged opposite each other on the outer wall of the rudder stock tube or on the inner wall of the receiving shaft relative to the central axis of the rudder stock tube or the receiving shaft. By means of the form-fit and / or force-fit arrangement of these retainer elements and complementary retainer workpieces, a two-point retainer for the rudder stock tube in the receiving shaft is provided, which allows the rudder stock tube to pivot or move within the receiving shaft in order to align or adjust the rudder stock tube. By means of at least three retainer elements and three complementary retainer workpieces, a particularly advantageous three-point retainer can be ensured. This is particularly particularly advantageous if four retainer elements and four complementary retainer workpieces are provided. In this case, the rudder stock tube has a particularly stable support in the receiving shaft.

[0023] It is furthermore advantageous if at least one retainer element is formed as a single piece with the rudder stock tube and / or is connected to the rudder stock tube in a materially bonded and / or form-fit and / or force-fit manner, and / or if the at least one complementary retainer workpiece is formed as a single piece with the receiving shaft and / or is connected to the receiving shaft in a materially bonded and / or form-fit and / or force-fit manner.

[0024] The materially bonded connection of the retainer element to the rudder stock tube or of the complementary retainer workpiece to the receiving shaft can be achieved, for example, by welding or gluing.

[0025] If at least one retainer element and / or at least one complementary retainer workpiece is connected to the rudder stock tube and / or the receiving shaft in a form-fit and / or force-fit manner, this connection can be established by inserting the retainer element or the complementary retainer workpiece into a corresponding receptacle in the outer wall of the rudder stock tube or the inner wall of the receiving shaft. The form-fit and / or force-fit connection can also be achieved by providing fastening elements, such as screws, bolts, adhesives, clamps, etc.

[0026] It is furthermore advantageous if the at least one retainer element and / or the at least one complementary retainer workpiece is a pin or a bolt, preferably a threaded bolt, or a protrusion or a plate or a bar or a profile body, preferably a U-shaped profile body, and / or the at least one retainer element and / or the at least one complementary retainer workpiece is a receptacle, in particular a drilled hole and / or a blind hole, preferably with an internal thread or a recess, in particular a groove and / or a thread, in particular a thread pitch, and / or the at least one retainer element and / or the at least one complementary retainer workpiece is a clamping element, in particular a clamping ring.

[0027] The at least one complementary retainer workpiece and the at least one retainer element can be designed differently or identically. In a preferred embodiment, the retainer element is designed in the form of a pin, a bolt, a protrusion, a plate or a bar. The pin, the bolt, the protrusion, the plate or the bar then protrudes in a substantially radial direction from the outer wall of the rudder stock tube. On the other hand, the complementary retainer workpiece can be designed as a profile body, preferably as a U-shaped profile body comprising a contact surface, wherein the profile body, preferably the U-shaped profile body, protrudes substantially radially from the inner wall of the receiving shaft into the interior space of the receiving shaft.

[0028] In one embodiment, when the complementary retainer workpiece is a U-shaped profile body and the retainer element is a pin, a bolt, a protrusion, a plate or a bar, the retainer element can be hung into the U-shaped profile body. To this end, the retainer element is inserted between the fins of the U-shaped profile body and placed on the base section of the U-shaped profile body. In this embodiment, a twisting of the rudder stock tube in the receiving shaft can also be prevented or limited, since the retainer element formed as a pin, a bolt, a plate, a bar or a protrusion hits the fins of the U-shaped profile body in an attempt to twist the rudder stock tube. A rotational brake is provided by the interaction of the retainer element and the complementary retainer workpiece.

[0029] In principle, the retainer element on the rudder stock tube can also be designed as a U-shaped profile body, while the complementary retainer workpiece is formed as a pin, a bolt, a protrusion, a plate or a bar at the receiving shaft. For both options, only the orientation of the U-shaped profile body has to be considered.

[0030] If the U-shaped profile body is arranged as a complementary retainer workpiece on the receiving shaft, the fins of the U-shaped profile body in the receiving shaft must be oriented upwards in the vertical direction, so that the retainer element of the rudder stock tube formed as a pin, a bolt, a protrusion, a plate or a bar can be inserted into the U-shaped profile body from above.

[0031] On the other hand, if the U-shaped profile body is a retainer element on the rudder stock tube, the fins of the U-shaped profile body of the rudder stock tube must be aligned downwards in the vertical direction, so that the U-shaped profile body can be placed from above on the complementary retainer workpiece of the receiving shaft formed as a pin, a bolt, a protrusion, a plate or a bar. The terms "vertical direction", "upwards" and "downwards" refer to the situation of the rudder stock tube in the receiving shaft on the ship.

[0032] However, other embodiments of the retainer element and the complementary retainer workpiece are possible in addition to these preferred embodiments.

[0033] The retainer element or the complementary retainer workpiece can thus be a threaded bolt. The respective complementary retainer workpiece or the respective retainer element is then formed as a receptacle, in particular a bore, which preferably has an internal thread. The threaded bolt can be screwed onto the retainer or onto the internal thread in the bore. By determining the screwing-in depth, the rudder stock tube can be aligned or adjusted in the receiving shaft, in particular in the radial direction of the receiving shaft.

[0034] Another preferred possibility is that the retainer element is a recess, in particular a circumferential recess, which is preferably a groove around the rudder stock tube. The complementary retainer workpiece can be formed as a clamping element, in particular a clamping ring, which is further preferably also arranged in a groove in the inner wall of the receiving shaft. If the rudder stock tube is inserted into the receiving shaft, the clamping element formed as the complementary retainer workpiece can both intervene in the recess on the rudder stock tube and in the recess, in particular the groove, of the receiving shaft, thereby facilitating or ensuring a form-fit and / or force-fit support of the rudder stock tube in the receiving shaft. In principle, however, the complementary retainer workpiece designed as a clamping element can also be designed differently from the clamping ring and the recess, as long as the clamping element and the respective retainer element together produce a force-fit and / or form-fit clamping between the rudder stock tube and the receiving shaft.

[0035] Another possibility is that the retainer element and / or the complementary retainer workpiece are designed as a thread, wherein an external thread is arranged on the rudder stock tube and an internal thread is arranged in the receiving shaft. In this case, the rudder stock tube can be screwed into the receiving shaft, wherein the retainer element and the complementary retainer workpiece are designed as an internal thread and an external thread to provide a form-fit and force-fit connection. By suitable embodiments of the thread, in particular the division of the thread, mobility of the rudder stock tube in the receiving shaft can be made possible, so that the rudder stock tube can be aligned at the actual propeller axis and the actual stern tube on the ship. After alignment, the rudder stock tube can be fixed inside the receiving shaft using an adhesive.

[0036] It is furthermore advantageous if the at least one retainer element and the at least one complementary retainer workpiece project into an intermediate space between the rudder stock tube and the receiving shaft, wherein the at least one complementary retainer workpiece and / or the at least one retainer element is arranged obliquely with respect to the axial direction of the rudder stock tube or the receiving shaft with respect to the respective radial direction.

[0037] In the state in which the receiving shaft and the rudder stock tube are mounted on the hull, the holder elements and / or the complementary holder pieces are preferably aligned slightly obliquely downwards and / or upwards. Due to this slight obliquity in the axial direction, a particularly advantageous alignment and adjustment of the rudder stock tube in the receiving shaft can be ensured. For example, if two U-profile bodies are arranged opposite one another in the receiving shaft as complementary holder pieces, with the flanges of the U-profile bodies pointing upwards, and with the course of the U-profile bodies into the interior space of the receiving shaft in the radial direction having a slight downward obliquity, and on the other hand two bolts are arranged as holder elements on the outer wall of the rudder stock tube, the bolts can be inserted into the U-profile bodies from above to establish a form and force fit connection or support. If the rudder stock tube is now aligned, i.e. in particular the central axis of the rudder stock tube is aligned with the central axis of the receiving shaft, this can be achieved by moving the rudder stock tube in the receiving shaft approximately in the radial direction. Then, one of the bolts is guided slightly downwards along the slightly obliquely downwards directed U-profile body, while the other bolt is guided slightly upwards within the second U-profile body. As a result of this, the central axis of the rudder stock tube is oblique with respect to the central axis of the receiving shaft. The same effect also occurs with at least three or at least four or exactly four holder elements or complementary holder pieces.

[0038] It is furthermore advantageous if at least two holder elements are arranged on the outer circumference of the rudder stock tube, preferably uniformly, and / or at least two complementary holder pieces are arranged on the inner circumference of the receiving shaft, preferably uniformly.

[0039] The uniform arrangement of the holder elements and the complementary holder pieces allows for an easy manufacture as well as an easy alignment and adjustment of the rudder stock tube in the receiving shaft.

[0040] It is advantageous if at least two holder elements on the outer circumference of the rudder stock tube, spaced apart in the circumferential direction, and / or at least two complementary holder pieces on the inner circumference of the receiving shaft, spaced apart in the circumferential direction, are arranged in such a way that the holder elements can be guided past the complementary holder pieces in the axial direction when the rudder stock tube is inserted into the receiving shaft.

[0041] In the state in which the receiving shaft is arranged on the hull, in particular on the stern portion, and in the case of a downwardly directed keel of the stern portion or of the hull, the rudder stock tube can be inserted into the receiving shaft from below. The holder elements are thereby guided past the complementary holder pieces of the receiving shaft, which can then form a form fit and / or force fit arrangement with the complementary holder pieces, preferably hindering or preventing a movement of the rudder stock tube in the direction of insertion.

[0042] It can be particularly advantageous if the rudder stock tube, if the intermediate space is not filled, can be arranged and / or arranged so as to be arranged axially movably in the receiving shaft, such that the at least one holder element can be arranged at the at least one complementary holder workpiece, in particular be aligned, and / or such that the at least one holder element can be placed on the complementary holder workpiece, in particular be aligned.

[0043] Furthermore, it can be advantageous if the rudder stock tube, if the intermediate space is not filled, can be arranged and / or arranged so as to be arranged axially movably in the receiving shaft, such that the at least one holder element can be arranged at the at least one complementary holder workpiece, in particular be aligned, and / or such that the at least one holder element can be placed on the complementary holder workpiece, in particular be aligned.

[0044] In this case, it can be particularly advantageous if the rotatable arrangement of the rudder stock tube is such that, after the holder element has been guided past the complementary holder workpiece when inserting the rudder stock tube into the receiving shaft from below, the holder element and the complementary holder workpiece can be aligned by turning the rudder stock tube before the holder element and the complementary holder workpiece are arranged relative to each other. The holder provided in this way is functionally similar to a bayonet lock.

[0045] When inserting the rudder stock tube into the receiving shaft from below, the rudder stock tube is first aligned to enable the holder element to be guided past the complementary holder workpiece. Once the holder element is above the complementary holder workpiece, the rudder stock tube can be rotated such that the holder element is aligned in the axial direction of the rudder stock tube or the receiving shaft is aligned with the complementary holder workpiece. Subsequently, the rudder stock tube can be moved axially downwards, wherein the holder element forms a form-fit and / or force-fit connection with the complementary holder workpiece and holds the rudder stock tube in the receiving shaft.

[0046] It can be advantageous to provide that, in the state arranged in the receiving shaft, in particular when the rudder stock comprising the rudder stock tube and the receiving shaft is arranged on the ship, the rudder stock tube can be aligned within the receiving shaft, in particular if the intermediate space is not filled.

[0047] The adjustment of the rudder stock tube arranged in the receiving shaft can thus be carried out particularly advantageously in the state arranged on the ship, i.e. compared to the actual propeller axis or the actual stern tube. The adjustment is preferably carried out if the intermediate space has not yet been filled with adhesive. However, it can also be carried out if the intermediate space, preferably in sections, is filled with adhesive. If the adhesive is a cast plastic, the alignment or adjustment can be carried out as the cast plastic hardens.

[0048] Preferably, the rudder stock tube can be moved within the receiving shaft to align and adjust relative to the radial direction of the receiving shaft.

[0049] It is furthermore advantageous if an adjustment member can be provided, wherein the adjustment member is designed to adjust the position and / or the orientation of the rudder stock tube in the receiving axis, in particular the position of the rudder stock tube on the receiving axis with respect to the radial direction of the receiving axis and / or the angle between the central axis of the rudder stock tube and the central axis of the receiving axis, in particular in the case of adjacent holder elements and complementary holder workpieces.

[0050] The adjustment member can be an additional element, but the adjustment member can also be part of the holder element and / or the complementary holder workpiece. For example, the holder element and / or the complementary holder workpiece are adjustable. In a preferred embodiment, the inclination angle of the holder element and / or the complementary holder workpiece can be adjusted.

[0051] It is furthermore advantageous if an adjustment member, preferably a screw and / or a spacer element, preferably a washer, can be provided, wherein the adjustment member is preferably arranged on at least one holder element and / or at least one complementary holder workpiece.

[0052] Preferably, the intermediate space between the outer wall of the rudder stock tube and the inner wall of the receiving axis 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 axis increases or decreases at least in some regions in the axial direction of the rudder stock tube. It is particularly preferred that the gap width of the intermediate space between the outer wall of the rudder stock tube and the inner wall of the receiving axis increases at least in certain regions, viewed in the axial direction of the rudder stock tube upwards, that is to say, in the state in which the rudder stock or the receiving axis is arranged on a ship, in particular a ship, in particular in the direction of the ship's hull.

[0053] The increase in the gap width can be achieved by at least regional increase in the inner diameter of the receiving axis in the state in which it is arranged on the ship in the direction of the ship's hull and / or by at least partial reduction of the outer diameter of the rudder stock tube in the state in which it is arranged on the ship in the direction of the ship's hull. It is particularly preferred that the rudder stock tube wall thickness, viewed in the axial direction of the rudder stock tube, is reduced, wherein the inner diameter of the rudder stock tube remains constant in the axial direction and the outer diameter is reduced.

[0054] In the state in which the rudder stock tube is arranged in the receiving axis, the rudder stock tube is arranged above a clamping height within the receiving axis. The clamping height is preferably formed between the lower end or the outer side of the receiving axis and an upper region of the rudder stock tube, in particular the upper end of the rudder stock tube. Preferably, the gap width increases at least partially in the course of the clamping height. In this case, it is particularly preferred that the lower region of the clamping height can have a constant gap width. In order to increase the gap width regionally, it increases above the region with the constant gap width.

[0055] Furthermore, the gap width can be reduced again in an upper range of the clamping height seen in the axial direction. The reduction of the gap width in the upper region of the clamping height can be caused by the complementary retainer workpiece and / or the retainer element of the retainer protruding into the intermediate space. Furthermore, the reduction of the gap width in the upper region of the clamping height can also be achieved by a, in particular circumferential, flange on the inner wall of the receiving shaft or the outer wall of the rudder stock tube in the upper region.

[0056] However, it is also conceivable in principle that the gap width between the outer wall of the rudder stock tube and the inner wall of the receiving shaft is locally increased at least in the axial direction of the rudder stock tube, i.e. in the state in which the rudder stock tube or the receiving shaft is arranged on the ship, in particular on a ship, in particular in the direction away from the ship body.

[0057] It is furthermore advantageous that at least in some regions the intermediate space can be filled or filled with adhesive, preferably with cast plastic, in particular with cast resin.

[0058] The intermediate space is at least partially filled with adhesive, in particular with cast plastic, preferably only after the rudder stock tube has been aligned and adjusted in the receiving shaft. Once the rudder stock tube and the receiving shaft are firmly connected by the adhesive, for example once the cast plastic has hardened, a fixed, aligned or adjusted rudder stock tube is obtained in the receiving shaft, thereby providing a particularly high hydrodynamic efficiency. Furthermore, by means of the retainer element and the complementary retainer workpiece, which are preferably still present in the intermediate space, even in the event of a failure of the adhesive, for example when the cast plastic leaks, a slipping of the rudder stock tube can be prevented.

[0059] It is particularly preferred that the intermediate space is filled with adhesive only in the lower region of the clamping height having a constant gap width. Furthermore, or alternatively, the intermediate space can also be filled only in the upper region of the clamping height, in particular in the region of the retainer element and / or the complementary retainer workpiece and / or the flange with adhesive. It is particularly preferred that the intermediate space in the region of the increasing gap width is not filled with adhesive.

[0060] It is furthermore advantageous that a sealing element, in particular a sealing sleeve, can be provided, wherein the sealing element is attached to the outside of the rudder stock such that a leakage of the adhesive to the outside when filling the intermediate space is preventable by said sealing element, wherein preferably the sealing element can be removed, in particular after the intermediate space has been filled.

[0061] In the state in which the rudder stock is arranged on the ship, the outer side of the rudder stock corresponds to the outer side of the hull, preferably to the region of the hull which encloses the outer opening of the receiving shaft. At the location of the receiving shaft on the ship, the rudder stock tube can be inserted into the receiving shaft from below. Subsequently, the sealing element, in particular the sealing sleeve, is attached to the outer side of the hull and thus to the outer side of the rudder stock, which seals the intermediate space between the rudder stock tube and the receiving shaft from below. After connecting the sealing element, the intermediate space between the rudder stock tube and the receiving shaft can be filled with adhesive, in particular casting plastic, wherein the sealing element prevents the adhesive from leaking out of the intermediate space, in particular downwards to the outer side of the rudder stock or the outer side of the hull. After filling the intermediate space with adhesive, the sealing element can remain on the hull or on the outer side of the rudder stock. However, it is also possible to remove the sealing element after filling the intermediate space with adhesive. If the sealing element remains on the hull or on the outer side of the rudder stock, further protection against leakage of the adhesive, in particular the casting plastic, can be provided. On the other hand, if the sealing element is removed, it can be reused.

[0062] It is furthermore advantageous if the sealing element is designed as a single piece, in particular consists of one component or a plurality of components.

[0063] The multi-component design of the sealing element allows the sealing element to be attached particularly simply on the outer side of the rudder stock or on the outer side of the hull.

[0064] It is furthermore advantageous if the sealing element, in particular the annular sealing element, comprises a frame and / or an O-ring and / or an elastomer.

[0065] If the sealing element has at least one through-portion, in particular an opening or a channel, a further advantage is provided, wherein the adhesive can be introduced through the opening, in particular into the intermediate space.

[0066] If the sealing element is located on the outer side of the rudder stock or in the region of the rudder stock on the outer side of the hull, the intermediate space can be accessed from the outside of the ship through the through-portion, in particular through the opening or the channel. This provides a particularly easy way of filling the intermediate space.

[0067] The opening can be closable in order to prevent the adhesive, in particular the casting plastic, from leaking after filling the intermediate space. Furthermore, a hose for introducing the adhesive can be passed through the opening. Thus, the formation of air bubbles in the adhesive, in particular in the casting plastic, can be prevented.

[0068] It is furthermore advantageous if the adhesive, in particular the casting plastic, can be liquefied, preferably by means of heat input, such that the rudder stock tube can be removed from the receiving shaft after the adhesive has been liquefied.

[0069] If the adhesive, in particular the casting plastic, can be liquefied by heat input, the replacement of the rudder stock tube is simplified. Thus, if the rudder stock tube needs to be replaced, the adhesive can be liquefied by heat input. The rudder stock tube can then be detached from the receiving shaft on the hull. For this purpose, in the preferred embodiment, after liquefying the adhesive, the rudder stock tube has to be raised vertically so that the rudder stock tube is moved upwards in the receiving shaft. Subsequently, the rudder stock tube is rotated so that the previously aligned holder elements and the complementary holder pieces are twisted towards each other. Subsequently, the rudder stock tube can be guided axially downwards from the receiving shaft, wherein the holder elements are guided past the complementary holder pieces. A new rudder stock tube can then be inserted.

[0070] It is furthermore advantageous if the heating element, in particular the heating wire, is arranged in the intermediate space and preferably embedded into the adhesive.

[0071] By providing a heating element, in particular a heating wire, the replacement of the rudder stock tube is further simplified. By means of the heating element, in particular the heating wire, thermal energy can be introduced uniformly into the adhesive for exchange to liquefy it uniformly.

[0072] It is furthermore advantageous if recesses, in particular grooves or drillings, can be provided on the outside and / or the inside of the rudder stock tube and / or the receiving shaft, wherein signal conducting means, in particular electrical cables, are preferably provided in the recesses.

[0073] For sensors to be connected to the rudder stock or the rudder stock tube, the receiving shaft or the rudder stock shaft, grooves or drillings can be provided in the rudder stock tube or the receiving shaft to guide appropriate signal conducting means, for example electrical cables. Preferably, the signal conducting means can be guided in the intermediate space between the rudder stock tube and the receiving shaft and led out at the receiving shaft or the rudder stock tube, preferably at the point of minimum load.

[0074] Preferably, the adjacent holder elements, in particular bolts or rods, and the complementary holder pieces, in particular profile bodies or U-shaped profile bodies, limit or prevent the rotation of the rudder stock tube when a rotational or torsional force acts on the rudder stock tube.

[0075] Thus, the holder elements and the complementary holder pieces preferably represent a rotational brake. This further improves the force transmission of the rudder stock to the hull. In particular, if the complementary holder pieces are formed as U-shaped profile bodies and if the holder elements are formed as bolts, pins, protrusions, rods or plates, which are arranged between the fins of the U-shaped profile bodies forming the complementary holder pieces, the twisting of the rudder stock tube in the receiving shaft is prevented. However, it can be possible to allow a slight twisting. This can be achieved by the distance between the wings of the U-shaped profile body being greater than the width of the holder elements arranged between the fins. Since a small amount of rotation is allowed, manufacturing tolerances can be compensated when aligning the rudder stock tube to the receiving shaft.

[0076] A further solution of the object of the present application is to provide a rudder device for a ship, in particular a ship, having a rudder and a rudder shaft as described above.

[0077] A further solution of the object of the present application is to provide a ship, in particular a ship, having a rudder shaft as described above.

[0078] A further solution of the object of the present application is to provide a rudder shaft tube for a rudder shaft as described above, wherein the rudder shaft tube comprises at least one holder element.

[0079] The holder element can be formed according to the above-described embodiments.

[0080] A further solution of the object of the present application is to provide a receiving shaft for a rudder shaft as described above, wherein the receiving shaft has at least one complementary holder piece.

[0081] The complementary holder piece can be formed according to the above-described embodiments.

[0082] A further solution of the object of the present application is a kit for a rudder shaft as described above, which comprises at least one, in particular the previously described, holder element and at least one, in particular the previously described, complementary holder piece, wherein the kit preferably comprises a rudder shaft tube and / or a receiving shaft.

[0083] The rudder shaft tube and the receiving shaft can also be formed according to one of the above-described embodiments.

[0084] Furthermore, the basic object of the present application is achieved by providing a method for producing a rudder shaft as described above, in particular having a receiving shaft as described above and a rudder shaft tube as described above, in a ship, wherein a ship, in particular a ship, further in particular a stern portion, is provided, wherein a receiving shaft is arranged in the ship, wherein the rudder shaft tube is introduced into the receiving shaft, wherein the at least one holder element is passed through the at least one complementary holder piece, wherein the rudder shaft tube is rotated such that the at least one holder element and the at least one complementary holder piece are aligned in the axial direction of the rudder shaft tube and / or in the axial direction of the receiving shaft, wherein the rudder shaft tube is moved in the axial direction such that the at least one holder element and the at least one complementary holder piece are opposite to each other, in particular rest on each other.

[0085] With the above-described ship, rudder shaft tube, receiving shaft, kit for a rudder shaft and method for producing a rudder shaft, the advantages according to the present application are achieved.

[0086] The method according to the application particularly allows the rudder stock tube to be inserted into the receiving shaft, wherein the receiving shaft is arranged in a stern portion of the hull, and wherein the stern portion has an upper deck which is oriented upwards, or in other words wherein the keel of the hull is oriented downwards. In particular, in the method according to the application, the rudder stock tube does not have to be inserted into the receiving shaft of the inverted stern portion from above, but can be inserted into the receiving shaft from below in the case of a hull with a downward-oriented keel. This makes it possible to align the rudder stock tube with the actual propeller axis and the actual stern tube.

[0087] This particularly increases the hydrodynamic efficiency of the rudder device.

[0088] It is advantageous that the keel of the ship can be arranged to be oriented downwards, and that the rudder stock tube is inserted vertically into the receiving shaft from below.

[0089] This possibility of inserting the rudder stock tube vertically into the receiving shaft from below allows the rudder stock tube to be adjusted or aligned with respect to the actual propeller axis and the actual stern tube.

[0090] It is furthermore advantageous that the rudder stock tube in the receiving shaft can be aligned with an adjustment member, wherein aligned is the propeller axis and / or the stern tube of the ship.

[0091] The adjustment member can be part of or identical to a retainer element or a complementary retainer piece. Furthermore, the adjustment member can also be designed as a washer or the like.

[0092] It is furthermore advantageous that the intermediate space between the rudder stock tube and the receiving shaft is filled with an adhesive, in particular a casting plastic, and wherein the adhesive, in particular the casting plastic, is cured.

[0093] By filling the intermediate space with an adhesive, in particular with a casting plastic, it is possible to fix the rudder stock tube, which is aligned with the actual propeller axis or the actual stern tube, in the receiving shaft.

[0094] It is furthermore advantageous that a sealing element is provided, which is arranged on the outside of the rudder stock, in particular on the outside of the ship, in particular on the outside of the hull, so that when filling the intermediate space, the adhesive is prevented from leaking out by means of the sealing element.

[0095] It is furthermore advantageous that it can be provided that, after the adhesive, in particular the casting plastic, has hardened, the sealing element, in particular on the outside of the rudder stock, in particular on the outside of the ship, in particular on the outside of the hull, is left or removed.

[0096] It is particularly preferred that a heating element, in particular a heating wire, is arranged in the intermediate space. SUMMARY

[0111] Figure 1A rudder stock 100 comprising a rudder stock tube 10 and a receiving shaft 11 is shown. The rudder stock 100 is arranged in a hull 12 of a ship 13. The hull 12 comprises an outer side 14. The rudder stock tube 10 is formed as a hollow tube 15 and is inserted into the receiving shaft 11 from below along a vertical direction 16 from the outer side 14 of the hull 12. In a state in which the rudder stock tube 10 is arranged in the receiving shaft 11, an intermediate space 19 is formed between an outer wall 17 of the rudder stock tube 10 and an inner wall 18 of the receiving shaft 11. The rudder stock 100 comprises a retainer 20 for holding the rudder stock tube 10 within the receiving shaft 11. The retainer 20 comprises retainer elements 21 which are attached to the outer wall 17 of the rudder stock tube 10 in a material bond, form fit or force fit. Furthermore, the retainer 20 comprises complementary retainer pieces 22 which are arranged on the inner wall 18 of the receiving shaft 11 in a form fit, material bond or force fit. Each complementary retainer piece 22 protrudes into the intermediate space 19 from the inner wall 18 of the receiving shaft 11 along a radial direction 23. Likewise, each retainer element 21 protrudes into the intermediate space 19 from the outer wall 17 of the rudder stock tube 10 along the radial direction 23. Furthermore, in the intermediate space 19, there is an adhesive 24 which is designed as a cast plastic 25 and which ensures that the rudder stock tube 10 is firmly fixed in the receiving shaft 11. Furthermore, the rudder stock tube 10 extends in an axial direction 26.

[0112] A first embodiment of the retainer 20 is shown in Figure 2a and 2b .

[0113] Figure 2a A top view of the rudder stock tube 10 and the receiving shaft 11 with respect to the axial direction 26 is shown. Figure 2b A view of the complementary retainer pieces 22 arranged on the inner wall 18 of the receiving shaft 11 and the retainer elements 21 arranged on the outer wall 17 of the rudder stock tube 10 along the section line A-A in Figure 2a is shown.

[0114] The rudder stock tube 10 comprises four retainer elements 21a to 21d which protrude into the intermediate space 19 from the outer wall 17 of the rudder stock tube 10. On the inner wall 18 of the receiving shaft 11, four complementary retainer pieces 22a to 22d are arranged which also protrude into the intermediate space 19. The retainer elements 21a to 21d and the complementary retainer pieces 22a to 22d are arranged uniformly spaced apart along the outer circumference of the rudder stock tube 10 or along the inner circumference of the receiving shaft 11. As Figure 2bAs shown, the complementary retainer workpiece 22 or 22a to 22d is designed as a profiled body 29, in particular a U-shaped profiled body 28. The U-shaped profiled body 28 comprises a wing 30 and a base 31. The retainer element 21 or 21a to 21d is designed as a rod 32 and is placed on the base 31 of the complementary retainer workpiece 22 or 22a to 22d formed as a U-shaped profiled body 28. By placing the rod 32 on the base 31 of the U-shaped profiled body 28, the rudder stock tube 10 is hindered or prevented from moving in the axial direction 26 downwards. The wing 30 of the U-shaped profiled body 28 also serves as a rotation stop 33. Thus, Figure 2a and 2b The rudder stock tube 10 shown can only be rotated slightly in the receiving shaft 11 before the rod 32 of the retainer element 21a to 21d hits the wing 30 of the U-shaped profiled body 28. In Figure 2a the intermediate space 19 between the rudder stock tube 10 and the receiving shaft 11 is not filled. Thus, the rudder stock tube 10 can be aligned or adjusted within the receiving shaft 11. To this end, a Figure 2b pad element 34 can be provided. By arranging the pad element 34 between the rod 32 and the base 31 of the U-shaped profiled body 28, the rudder stock tube 10 can be adjusted in the receiving shaft 11. Figure 2c and 2d The possibility of adjusting the rudder stock tube 10 in the receiving shaft 11 is shown. Thus, as Figure 2c shown, the rudder stock tube 10 can be moved laterally in the receiving shaft 11 so 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. Figure 2d In a very exaggerated manner, it is shown that by arranging the pad element 34 between the retainer element 21 and the complementary retainer workpiece 22, the angle a between the central axis 35 of the rudder stock tube 10 and the central axis 36 of the receiving shaft 11 can be adjusted. After alignment, the intermediate space 19 can be filled with adhesive 24, in particular cast plastic 25. After the adhesive 24 has hardened, the rudder stock tube 10 is fixed within the receiving shaft 11.

[0115] To manufacture the rudder shown according to Figures 1 to 2d the rudder stock tube is inserted into the receiving shaft 11 from the outside 14 of the hull 12 in the vertical direction 16 Figure 1 ). To this end, as Figure 3As shown, the rudder stock tube 10 is rotated relative to the receiving shaft 11 such that the holder elements 21a to 21d and the complementary holder pieces 22a to 22d are not aligned with each other. In this position, the rudder stock tube 10 can be introduced into the receiving shaft 11 in the vertical direction 16 such that the holder elements 21a to 21d are guided past the complementary holder pieces 22a to 22d until the holder elements 21 to 21d are arranged above the complementary holder pieces 22a to 22d. Subsequently, by rotating the rudder stock tube 10 about the central axis 35 of the rudder stock tube 10, the holder elements 21a to 21d can be aligned with the holder elements 22a to 22d, as Figure 2a shown. Subsequently, the rudder stock tube 10 can be moved in the axial direction 26 or downward in the vertical direction 16 such that the holder elements 21a to 21d, in particular the holder elements 21a to 21d formed as bars 32, are arranged at the complementary holder pieces 22a to 22d, in particular those complementary holder pieces 22a to 22d formed as U-shaped profile bodies 28. By arranging the holder elements 21a to 21d at the complementary holder pieces 22a to 22d, a holder 20 is formed which prevents or hinders the movement of the rudder stock tube within the receiving shaft 11 in the axial direction 26 Figure 1 ). Subsequently, the rudder stock tube 10 can be aligned, in particular with respect to the propeller axis or the skeg. In order to fix the rudder stock tube 10 in the receiving shaft, the intermediate space 19 is subsequently filled with adhesive 24.

[0116] Another embodiment of the holder 20 is shown in Figure 4 Fig. 6. For the embodiments of Figure 1 and 2a the difference to the embodiment according to Figure 4 is only that the holder elements 21 or 21a to 21d are designed as bars 32 which protrude in the radial direction 23 into the intermediate space 19 between the rudder stock tube 10 and the receiving shaft 11 and are inclined upwardly with respect to the axial direction 26. This leads to the fact that by moving the rudder stock tube 10 in the receiving shaft 11 in the radial direction 23, the holder elements 21 or 21a to 21d in the complementary holder pieces 22 or 22a to 22d designed as U-shaped profile bodies 28 receive an additional component of the movement in the axial direction 26 or the counter-axial direction 26 due to the inclination. Thus, the central axis 35 of the rudder stock tube 10 is aligned with the central axis 36 of the receiving shaft 11.

[0117] Figure 5a and 5b Fig. 7 shows another embodiment of the holder 20. Figure 5a and 5bA possible embodiment of a holder 20 using clamping elements is shown. The holder element 21 in the rudder stock tube 10 is formed as a recess 37, in particular a groove 38. The recess 37 is formed circumferentially around the rudder stock tube 10. The complementary holder piece 22 is designed as a clamping element in the form of a clamping ring 39 and is arranged in a form-fit at the receiving shaft 11 by means of a second groove 40 around the inner wall 18 of the receiving shaft 11. The clamping ring 39 is not completely closed, but, according to Figure 5b , comprises a gap 41 at a certain point, which allows the clamping ring 39 to widen. When the rudder stock tube 10 is inserted 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 the groove 38 of the rudder stock tube 10 is arranged on the level of the clamping ring 39, the clamping ring 39 relaxes, so that the clamping ring 39 is inserted into the recess 37 and the groove 38 of the rudder stock tube 10 as shown. This prevents the rudder stock tube 10 from moving in the receiving shaft 11 in the axial direction 26 of the rudder stock tube 10. Instead of the clamping ring 39 and the groove 38, other clamping elements and appropriately formed holder elements 21 can also be used as complementary holder pieces 22, which produce a force-fit and / or form-fit clamping between the rudder stock tube 10 and the receiving shaft 11. Figure 5a

[0118] Furthermore, in Figure 1 , a sealing element 42 is shown, which is arranged on the outer side 14 of the hull 12. The sealing element 42 is designed as a sealing sleeve 43 and comprises a through- going portion 44, through which the adhesive 24, in particular the cast plastic 25, can be introduced into the intermediate space 19 between the rudder stock tube 10 and the receiving shaft 11. After the adhesive 24 has hardened, the sealing sleeve 43 can remain on the outer side 14 of the hull 12. Alternatively, the sealing sleeve 43 can be removed from the outer side 14 of the hull 12.

[0119] Figure 6 and Figure 7 ​A further rudder stock 100 is shown. The rudder stock 100 comprises a receiving shaft 11 arranged on a hull 12 of a ship 13. A rudder stock tube 10 is arranged in the receiving shaft 11 such that an intermediate space 19 is formed between an outer wall 17 of the rudder stock tube 10 and an inner wall 18 of the receiving shaft 11. The rudder stock tube 10 is arranged within the receiving shaft 11 above a clamping height 45. In a 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. Above the lower region 46 of the clamping height 45, seen in the axial direction 26 of the hull 12, or in other words seen from the perpendicular direction 16 of the rudder stock tube 10, a middle region 48 is provided in which the gap width 47 between the outer wall 17 of the rudder stock tube 10 and the inner wall 18 of the receiving shaft 11 increases in the direction of the hull 12. In order to increase the gap width 47, the rudder stock tube 10 has a wall thickness 49 which decreases in the upward direction. In an upper region 50 of the clamping height 45, a retainer element 21 is arranged on the outside of the rudder stock tube 10. A corresponding complementary retainer piece 22 is provided on the inner wall 18 of the receiving shaft 11. By means of the retainer element 21 or the complementary retainer piece 22, a reduction of the gap width 47 in the upper region 50 of the clamping height 45 is obtained. Instead of the retainer element 21 and / or the complementary retainer piece 22, a circumferential flange can also be provided. An adhesive 24, for example a cast plastic 25, is provided in the region of the retainer element 21 and the complementary retainer piece 22 within the upper region 50. Similarly, the adhesive 24 is provided within the lower region 46 of the gap width 47. The middle region 48 of the clamping height 45 is located between the upper region 50 and the lower region 46 of the clamping height 45, wherein the intermediate space 19 in the middle region 48 is not filled with adhesive 24.

[0120] In Figure 7 perspective view, the 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. Furthermore, the constant gap width 47 in the lower region 46 and in the region of the retainer element 21 or the complementary retainer piece 22 in the upper region 50, the adhesive 24 is shown which is designed as a cast plastic 25.
