Description

Rudder post for a watercraft, watercraft with a rudder post and method for producing a rudder post

Technical Field

The invention relates to a rudder stock for a ship, comprising a rudder stock trunk, a receiving shaft and a holder for holding the rudder stock trunk in the receiving shaft, wherein an intermediate space is provided between the rudder stock trunk and the receiving shaft in the state in which the rudder stock trunk is arranged in the receiving shaft. Furthermore, the invention relates to a vessel 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 the rudder stock.

Background

For the storage of large rudders, for example in commercial or container ships, so-called rudder bars are used in the prior art. The rudder stock of the steering engine is used for mounting the rudder shaft and transmitting rudder force into the ship. In the case of being arranged on a ship, the rudder stock comprises a receiving shaft arranged in the hull and a rudder stock trunk arranged in the receiving shaft. The rudder stock trunk can be fixed by welding or by gluing it in the receiving shaft. The rudder stock shaft is inserted into a rudder stock trunk fixed to the receiving shaft and is supported by axial and radial bearings.

A glued rudder stock is known from EP 2 583 892 A1 of the same applicant, wherein a rudder stock tube is arranged in the receiving shaft, and wherein an intermediate space is provided between a first part 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.

In the prior art, the mounting of the rudder stock trunk in the receiving shaft of the hull is done overhead. During the ship construction the stern portion, in which the rudder stock is arranged, is usually manufactured with a single 180 deg. turn up and down, i.e. with the upper deck down. Thus, the rudder trunk of the rudder stock is inserted into the stern portion from above. Only after the rudder stock has been placed and completed is the stern portion turned into an upright position, which means that the upper deck is facing upwards and connected to the hull of the ship, which hull comprises the propeller and the stern tube. Thus, until this moment, the alignment of the rudder stock trunk in the receiving shaft is independent of the actual propeller axis or stern tube.

However, for hydrodynamic efficiency it is advantageous if the rudder stock or the rudder stock trunk of the rudder stock is aligned or adjusted to the actual propeller axis or actual stern tube of the vessel. In the known rudder trunk mounting methods, it is not possible to refer to the actual propeller axis or stern tube, and such adjustment or alignment can only be done indirectly and expensive.

Summary of The Invention

The object of the present invention is to provide a rudder stock for a ship which is easy and inexpensive to manufacture and which can be installed into the hull when the stern section 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 increase the hydrodynamic efficiency.

Furthermore, it is an object of the present invention to provide a vessel 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, to achieve the above-mentioned advantages.

In order to solve the object underlying the invention, 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 an intermediate space is provided between the rudder stock tube and the receiving shaft in the state in which the rudder stock tube is arranged in the receiving shaft, wherein the holder comprises at least one holder element and at least one complementary holder piece, wherein the at least one holder element is arranged on the rudder stock tube, wherein the at least one complementary holder piece is arranged on the receiving shaft, and wherein the at least one holder element and/or the at least one complementary holder piece protrudes into the intermediate space in the state in which the rudder stock tube is arranged in the receiving shaft.

The rudder stock for ships according to the present invention includes a rudder stock trunk and a receiving shaft. The receiving shaft is intended to be mounted in a vessel, in particular in a stern portion of the vessel, or the receiving shaft is already located in the vessel. In the receiving shaft, the rudder stock trunk may be arranged to form a rudder stock or the rudder stock trunk may already be arranged in the receiving shaft. Furthermore, if the rudder stock trunk is attached to the receiving shaft of the hull, the rudder trunk shaft may be arranged in the rudder stock trunk.

In the state in which the rudder stock trunk is arranged in the receiving shaft, an intermediate space is provided between the rudder stock trunk and the receiving shaft, in particular between the outer wall of the rudder stock trunk and the inner wall of the receiving shaft. The entire intermediate space is preferably formed between the outer wall of the rudder stock trunk and the inner wall of the receiving shaft. At least one retainer element arranged on the rudder stock trunk and/or at least one complementary retainer piece arranged on the receiving shaft protrude into the intermediate space. The retainer element and the complementary retainer piece form a retainer for retaining the rudder stock trunk in the receiving shaft.

By holding the rudder stock tube in the receiving shaft by means of a holder consisting of at least one holder element and at least one complementary holder piece, it is possible to insert the rudder stock tube into the receiving shaft already mounted on the hull or to be mounted on the hull, in particular on the stern part, if the stern part is already connected to the hull, i.e. when the upper deck of the vessel, in particular of the stern part, is facing upwards, whereas in the prior art the mounting of the rudder stock in the receiving shaft of the hull is performed overhead, i.e. when the stern part of the vessel, in which the rudder stock is arranged, is rotated up and down by 180, i.e. the upper deck is facing downwards.

In contrast to the mounting methods known from the prior art, the rudder stock trunk of the rudder stock according to the invention can be introduced from below into the receiving shaft and held therein. 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 trunk held by the holder can be aligned with the actual propeller axis or the actual stern tube of the ship.

Thus the hydrodynamic efficiency can be improved with respect to rudder bars known from the prior art.

The configuration of the projection of the at least one retainer element and/or the at least one complementary retainer piece into the intermediate space in the state of the rudder stock tube being arranged in the receiving shaft provides a space-saving embodiment of the retainer for retaining the rudder stock tube in the receiving shaft, since no other elements of the retainer have to be arranged outside the receiving shaft.

However, if applicable, in order to align the rudder stock trunk in the receiving shaft inside and/or outside the receiving shaft, an alignment aid can be provided with which the rudder stock trunk can be held in an aligned position for alignment and subsequent fixing of the rudder stock trunk. However, it is preferable to remove the alignment aid after alignment and fixing.

After aligning or adjusting the rudder stock trunk in the receiving shaft to the actual propeller axis or to the actual stern tube, the intermediate space may be filled with an adhesive, preferably in sections, to fix the rudder stock trunk in the receiving shaft.

A further advantage of the rudder stock according to the invention is that after the rudder stock trunk has been connected or fixed, the holder remains in the rudder stock and thus the force can also be transferred through the holder. For example, in the event of an adhesive failure, protection against drooping or slipping of the rudder stock trunk may be provided.

Preferably, the at least one retainer element and the at least one complementary retainer piece can be arranged in and/or form-and/or force-fitting manner such that in a state in which the rudder stock tube is arranged in the receiving shaft, in particular in a state in which the rudder stock comprising the rudder stock tube and the receiving shaft is arranged on the vessel, a movement of the rudder stock tube in the receiving shaft in the axial direction of the rudder stock tube is hindered or prevented.

By means of the force-fit and/or form-fit arrangement of the complementary holder piece and the holder element, the rudder stock tube can be held in the mounted position in the receiving shaft when the keel of the hull is facing downwards, in particular in the state in which the rudder stock comprising the rudder stock tube and the receiving shaft is arranged on the vessel. In this case, the form-fitting and/or force-fitting arrangement of the retainer element and the complementary retainer piece impedes or prevents the rudder stock tube from moving in the axial direction of the rudder stock tube; in particular to prevent the rudder stock trunk from moving downwards out of the receiving shaft. In other words, the rudder stock trunk in the receiving shaft cannot slide in its axial direction, in particular cannot slide axially downwards. This allows the rudder stock trunk to be adjusted with respect to the actual propeller axis or stern tube of the vessel before the rudder stock trunk is fixed in the receiving shaft.

It is furthermore advantageous that at least two, preferably at least three, more preferably at least four, particularly preferably exactly four holder elements, and/or at least two, preferably at least three, more preferably at least four, particularly preferably exactly four complementary holder pieces can be provided.

If at least two retainer elements or at least two complementary retainer pieces are provided, they may preferably be arranged opposite each other on the outer wall of the rudder stock tube or on the inner wall of the receiving shaft with respect to the central axis of the rudder stock tube or the receiving shaft. By means of a form-fitting and/or force-fitting arrangement of these retainer elements and the complementary retainer pieces, a two-point retainer of the rudder stock tube is provided in the receiving shaft, which allows the rudder stock tube to be pivoted or moved within the receiving shaft for aligning or adjusting the rudder stock tube. By means of at least three holder elements and three complementary holder pieces, a particularly advantageous three-point holder can be ensured. This is particularly advantageous if four holder elements and four complementary holder pieces are provided. In this case, the rudder stock trunk has a particularly stable support in the receiving shaft.

It is furthermore advantageous if at least one retainer element is formed in one piece with the rudder stock tube and/or is connected to the rudder stock tube in a material-bonded and/or form-fitted and/or force-fitted manner and/or the at least one complementary retainer piece is formed in one piece with the receiving shaft and/or is connected to the receiving shaft in a material-bonded and/or form-fitted and/or force-fitted manner.

The material-bonded connection of the retainer element to the rudder stock trunk or the complementary retainer piece to the receiving shaft can be achieved, for example, by welding or gluing.

If at least one holder element and/or at least one complementary holder piece is connected to the rudder stock trunk and/or the receiving shaft in a form-fitting and/or force-fitting manner, such a connection can be established by inserting the holder element or the complementary holder piece into a corresponding receptacle in the outer wall of the rudder stock trunk or the inner wall of the receiving shaft. Form-fitting and/or force-fitting connections may also be achieved by providing fastening elements (e.g., screws, bolts, adhesives, clamps, etc.).

It is furthermore advantageous if at least one holder element and/or at least one complementary holder workpiece can be provided as a pin or a bolt, preferably as a threaded bolt, or as a projection or a plate or a bar or a profile body, preferably as a U-shaped profile body, and/or at least one holder element and/or at least one complementary holder workpiece is a container, in particular a borehole and/or a blind hole, preferably with an internal thread or recess, in particular a groove and/or a thread, in particular a thread number, and/or at least one holder element and/or at least one complementary holder workpiece is a clamping element, in particular a clamping ring.

The at least one complementary holder piece and the at least one holder 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 rod. The pins, bolts, protrusions, plates or bars then protrude from the outer wall of the rudder stock trunk in a substantially radial direction. On the other hand, the complementary holder piece 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 inner space of the receiving shaft.

In one embodiment, where the complementary retainer work piece is a U-shaped profile body and the retainer element is a pin, bolt, protrusion, plate or bar, the retainer element may hang into the U-shaped profile body. For this purpose, the retainer element is inserted between the wings of the U-shaped profile body and placed on the base section of the U-shaped profile body. In this embodiment, the torsion of the rudder stock tube in the receiving shaft can also be prevented or limited, because the retainer element formed as a pin, bolt, plate, bar or projection hits the tab of the U-shaped profile body in an attempt to twist the rudder stock tube. The rotation brake is provided by the interaction of the retainer element and the complementary retainer work piece.

In principle, the holder element on the rudder stock tube can also be designed as a U-shaped profile body, while the complementary holder piece is formed as a pin, a bolt, a projection, a plate or a rod at the receiving shaft. For both options, only the direction of the U-shaped profile body has to be considered.

If the U-shaped profile body is arranged as a complementary holder piece 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 holder element formed as a pin, bolt, projection, plate or rudder stock tube of the lever can be inserted into the U-shaped profile body from above.

On the other hand, if the U-shaped profile body is to be used as a holder 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 a complementary holder piece formed as a receiving shaft of a pin, bolt, protrusion, plate or rod. The terms "vertical", "upward" and "downward" refer to the condition of the rudder stock trunk in the receiving shaft on the vessel.

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

Thus, the retainer element or the complementary retainer work piece may be a threaded bolt. The corresponding complementary holder piece or the corresponding holder element is then formed as a container, in particular a bore, preferably with an internal thread. The threaded bolt may be screwed onto an internal thread in the holder or in the borehole. By determining the screw-in depth, the rudder stock trunk can be aligned or adjusted in the receiving shaft, in particular in the radial direction 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 trunk. The complementary holder workpiece may 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 elements formed as complementary retainer pieces can be inserted either into the recess on the rudder stock tube or into the recess of the receiving shaft (in particular into a groove), so that a form-fitting and/or force-fitting support of the rudder stock tube in the receiving shaft is facilitated or ensured. In principle, however, when the complementary holder piece is designed as a clamping element, the corresponding holder element can also be designed differently from the clamping ring and the recess, as long as the clamping element and the corresponding holder element together create a force-fit and/or form-fit clamping between the rudder stock tube and the receiving shaft.

Another possibility is that the holder element and/or the complementary holder piece are designed as threads, wherein an external thread is provided on the rudder stock trunk and an internal thread is provided 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 piece are designed as an internal thread and an external thread to provide a form-fitting and force-fitting connection. By a suitable embodiment of the screw thread, in particular the division of the screw thread, mobility of the rudder stock trunk in the receiving shaft is made possible, so that the rudder stock trunk can be aligned at the actual propeller axis and the actual stern tube on the vessel. After alignment, an adhesive may be used to secure the rudder stock trunk within the receiving shaft.

It is furthermore advantageous if at least one holder element and at least one complementary holder piece project 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 is arranged obliquely with respect to the rudder stock tube or the receiving shaft in the axial direction of the rudder stock tube or the receiving shaft with respect to the respective radial direction.

The retainer element and/or the complementary retainer piece are preferably aligned slightly downwardly and/or upwardly inclined in the state in which the receiving shaft and the rudder stock trunk are mounted on the hull. Due to this slight inclination in the axial direction, a particularly advantageous alignment and adjustment of the rudder stock trunk in the receiving shaft can be ensured. For example, if two U-shaped profile bodies are arranged as complementary retainer pieces in the receiving shaft opposite each other, wherein the wings of the U-shaped profile bodies are directed upwards, and wherein the course of the U-shaped profile bodies into the inner space of the receiving shaft in the radial direction has a slight downward inclination, and on the other hand two bolts are arranged as retainer elements on the outer wall of the rudder stock tube, the bolts can be inserted into the U-shaped profile bodies from above to establish a form and force fit connection or support. If the rudder stock trunk is now aligned, i.e. in particular the central axis of the rudder stock trunk is aligned with the central axis of the receiving shaft, this can be achieved by displacing the rudder stock trunk in a substantially radial direction in the receiving shaft. One of the bolts is then guided slightly downwards along the slightly downwardly sloping U-shaped profile body, while the other bolt is guided slightly upwards in the second U-shaped profile body. Thereby, the central axis of the rudder stock trunk is inclined with respect to the central axis of the receiving shaft. The corresponding effects also occur on at least three or at least four or exactly four retainer elements or complementary retainer pieces.

It is furthermore advantageous if at least two retainer elements can be provided which are arranged on the outer circumference of the rudder stock tube, preferably uniformly on the outer circumference of the rudder stock tube, and/or at least two complementary retainer pieces are preferably arranged on the inner circumference of the receiving shaft, preferably uniformly on the inner circumference of the receiving shaft.

The uniform arrangement of the retainer element and the complementary retainer piece allows for easy manufacture and easy alignment and adjustment of the rudder stock trunk in the receiving shaft.

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

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 stern portion or keel of the hull facing downwards, the rudder stock trunk can be inserted into the receiving shaft from below. The retainer element is thereby guided past the complementary retainer piece of the receiving shaft and can then form a form-fitting and/or force-fitting arrangement with the complementary retainer piece, preferably impeding or preventing the rudder stock tube from moving counter to the insertion direction.

It is particularly advantageous if the intermediate space is not filled, the rudder stock tube can be arranged or arranged rotatable in the receiving shaft such that the at least one holder element and the at least one complementary holder piece can be aligned with each other by rotating the rudder stock tube in the axial direction.

Furthermore, it may advantageously be provided that if the intermediate space is not filled, the rudder stock tube may be arranged and/or arranged axially movably in the receiving shaft such that the at least one retainer element may be arranged at the at least one complementary retainer piece, in particular aligned, and/or such that the at least one retainer element may be placed on the complementary retainer piece, in particular aligned.

In this case, it is particularly advantageous for the rotatable arrangement of the rudder stock tube to be such that, after the holder element has been guided past the complementary holder piece when the rudder stock tube is inserted into the receiving shaft from below, the holder element and the complementary holder piece can be aligned by rotating the rudder stock tube before the holder element and the complementary holder piece are arranged one another. The retainer provided in this way is similar in its function to a bayonet lock.

When inserting the rudder stock tube into the receiving shaft from below, the rudder stock tube is first aligned so that the retainer element can be guided through the complementary retainer piece. Once the retainer element is located above the complementary retainer piece, the rudder stock tube can be rotated such that the retainer element is aligned in the axial direction of the rudder stock tube or the receiving shaft is aligned with the complementary retainer piece. The rudder stock trunk can then be moved axially downwards, wherein the retainer element forms a form-and/or force-fitting connection with the complementary retainer piece and retains the rudder stock trunk in the receiving shaft.

It may advantageously be provided that in the state of being arranged in the receiving shaft, in particular when the rudder stock comprising the rudder stock trunk and the receiving shaft is arranged on a ship, the rudder stock trunk can be adjusted within the receiving shaft, in particular aligned if the intermediate space is not filled.

The adjustment of the rudder trunk arranged in the receiving shaft can thus be performed particularly advantageously in the state of being arranged on the vessel, i.e. compared to the actual propeller axis or the actual stern tube. If the intermediate space is not yet filled with adhesive, an adjustment is preferably made. However, filling with adhesive, preferably in sections, can also be carried out if the intermediate space is present. If the adhesive is a cast plastic, alignment or adjustment can be made as the cast plastic hardens.

Preferably, the alignment rudder stock trunk is movable within the receiving shaft to align and adjust in a radial direction relative to the receiving shaft.

Furthermore, it is advantageous if an adjusting member can be provided, wherein the adjusting member is designed such that, in particular in the case of adjacent holder elements and complementary holder pieces, the position and/or orientation of the rudder stock tube in the receiving shaft, in particular the position of the rudder stock tube on the receiving shaft with respect to the radial direction of the receiving shaft, and/or the angle between the central axis of the rudder stock tube and the central axis of the receiving shaft can be adjusted.

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

Furthermore, it is advantageous if an adjusting member can be provided for adjusting the screw and/or the spacer element, preferably a washer, wherein the adjusting member is preferably arranged on the at least one holder element and/or the at least one complementary holder workpiece.

Preferably, the intermediate space between the outer wall of the rudder trunk and the inner wall of the receiving shaft is expanded or reduced at least in the axial direction of the rudder trunk. In other words, the gap width of the intermediate space between the outer wall of the rudder stock trunk and the inner wall of the receiving shaft increases or decreases in the rudder stock trunk axial direction at least in some regions. It is particularly preferred that the gap width of the intermediate space between the outer wall of the rudder stock trunk and the inner wall of the receiving shaft increases, at least in certain areas, seen axially upwards from the rudder stock trunk, i.e. in the state in which the rudder stock or the receiving shaft is arranged on a ship, in particular in the direction of the ship's hull.

The increase in gap width may be achieved by: in the ship-mounted state in the direction of the ship, the inner diameter of the receiving shaft increases at least in regions, and/or in the ship-mounted state in the direction of the ship, the outer diameter of the rudder stock trunk decreases at least in part. 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 rudder stock tube inner diameter remains constant in the axial direction and the outer diameter is reduced.

In the state in which the rudder stock trunk is arranged in the receiving shaft, the rudder stock trunk is arranged above the clamping height in the receiving shaft. The clamping height is preferably formed between the lower end or the outer side of the receiving shaft and the upper region of the rudder stock trunk, in particular the upper end of the rudder stock trunk. Preferably, the gap width increases at least partially during 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 per area, it increases over an area having a constant gap width.

Furthermore, the gap width can be reduced again within the upper limit 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 holder workpiece of the holder and/or the holder element 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 particularly circumferential flange on the inner wall of the receiving shaft or on the outer wall of the rudder stock trunk in the upper region.

However, it is also conceivable in principle for the gap width between the outer wall of the rudder stock trunk and the inner wall of the receiving shaft to increase locally at least when looking down in the axial direction of the rudder stock trunk, i.e. in the state in which the rudder stock trunk or the receiving shaft is arranged on a ship, in particular in a direction away from the ship's hull.

It is furthermore advantageous that at least in some areas the intermediate space can be filled or filled with an adhesive, preferably with a casting plastic, in particular a casting resin.

The intermediate space is at least partially filled with adhesive, in particular cast plastic, preferably only after alignment and adjustment of the rudder stock trunk in the receiving shaft. Once the rudder stock tube and the receiving shaft are firmly connected by means of an 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 piece, which preferably remain in the intermediate space, slipping of the rudder stock trunk can be prevented even in case of adhesive failure, for example when the cast plastic leaks.

It is particularly preferred that the intermediate space is filled with adhesive only in the lower region of the clamping height with a constant gap width. In addition or as an alternative, the intermediate space can also be filled only in the upper region of the clamping height, in particular in the region of the holder element and/or the complementary holder workpiece and/or the flange. It is particularly preferred that the intermediate space in the region of increased gap width is not filled with adhesive.

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 leakage of adhesive to the outside is prevented by said sealing element when filling the intermediate space, wherein preferably the sealing element can be removed, in particular after filling the intermediate space.

In the state in which the rudder stock is arranged on the vessel, the outer side of the rudder stock corresponds to the outer side of the hull, preferably to the area of the hull surrounding the outer opening of the receiving shaft. In the position of the receiving shaft on the vessel, the rudder stock trunk can be inserted into the receiving shaft from below. Subsequently, a sealing element, in particular a sealing sleeve, is attached to the outside of the hull and thus to the outside of the rudder stock, which seals the intermediate space between the rudder stock trunk and the receiving shaft from below. After the connection of the sealing element, the intermediate space between the rudder stock tube and the receiving shaft can be filled with an adhesive, in particular cast plastic, wherein the sealing element prevents leakage of the adhesive from the intermediate space, in particular downwards to the outside of the rudder stock or the outside of the hull. After filling the intermediate space with adhesive, the sealing element may remain on the hull or outside the rudder stock. However, it is also possible to remove the sealing element after filling the intermediate space with adhesive. Further protection against leakage of adhesive, in particular cast plastic, can be provided if the sealing element is held on the hull or on the outside of the rudder stock. On the other hand, if the sealing element is removed, it can be reused.

Furthermore, it is advantageous if the sealing element is designed as a single piece, in particular is composed of one part or a plurality of parts.

The multipart design of the sealing element allows a particularly simple attachment of the sealing element on the outside of the rudder stock or on the outside of the hull.

Furthermore, it is advantageously possible to provide, in particular annular, sealing elements, including frames and/or O-rings and/or elastomers.

A further advantage is provided if the sealing element has at least one through-penetration, in particular an opening or a channel, through which the adhesive can be introduced, in particular into the intermediate space.

If the sealing element is located outside the rudder stock or outside the hull in the region of the rudder stock, it can pass through the through-penetration, in particular through the opening or the channel, from outside the vessel into the intermediate space. This provides a particularly easy way of filling the intermediate space.

The opening may be closable to prevent leakage of the adhesive, in particular the cast plastic, after filling the intermediate space. In addition, a hose for introducing adhesive may pass through the opening. Thus, the formation of bubbles in the adhesive, particularly in the cast plastic, can be prevented.

More advantageously, the adhesive, in particular the cast plastic, can be liquefied, preferably by heat input, so that the rudder stock tube can be removed from the receiving shaft after the adhesive has been liquefied.

If the adhesive, in particular the cast plastic, can be liquefied by heat input, the replacement of the rudder stock trunk is simplified. Thus, if a rudder stock tube needs to be replaced, the adhesive can be liquefied by heat input. The rudder stock trunk can then be detached from the receiving shaft on the hull. For this purpose, in a preferred embodiment, after liquefying the adhesive, the rudder stock trunk must be raised vertically so that the rudder stock trunk moves upwards in the receiving shaft. Subsequently, the rudder stock tube is rotated so that the previously aligned retainer element and the complementary retainer piece are twisted towards each other. The rudder stock trunk can then be guided axially downwards from the receiving shaft, wherein the retainer element is guided through the complementary retainer piece. A new rudder stock trunk can then be inserted.

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

By providing a heating element, in particular a heating wire, the replacement of the rudder stock trunk 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 so that it liquefies uniformly.

Furthermore, it is advantageous if a recess, in particular a groove or a borehole, can be provided on the outside and/or inside of the rudder stock tube and/or the receiving shaft, wherein a signal-conducting member, in particular a cable, is preferably provided in the recess.

For sensors to be connected to the rudder stock or rudder stock trunk, the receiving shaft or rudder lever shaft, a groove or a borehole may be provided in the rudder stock trunk or the receiving shaft to guide a suitable signal conducting member, such as a cable. Preferably, the signal-conducting member can be guided in the intermediate space between the rudder stock trunk and the receiving shaft and led out at the receiving shaft or rudder stock trunk, preferably at the minimum load point.

Preferably, when a rotational or torsional force acts on the rudder stock tube, the rotation of the rudder stock tube is limited or prevented by the adjacent retainer element, in particular the bolt or the rod, and the complementary retainer piece, in particular the profile body or the U-profile body.

Thus, the retainer element and the complementary retainer work piece preferably represent a rotation brake. This further improves the force transmission of the rudder stock to the hull. In particular, if the complementary holder piece is formed as a U-shaped profile body and if the holder element is formed as a bolt, pin, protrusion, rod or plate, which is arranged between the wings of the U-shaped profile body forming the complementary holder piece, the torsion of the rudder stock tube in the receiving shaft is prevented. However, it may be possible to allow for a slight twist. This can be achieved when the distance between the wings of the U-shaped profile body is greater than the width of the holder element arranged between the wings. Due to the small amount of rotation allowed, manufacturing tolerances can be compensated when aligning the rudder stock trunk with the receiving shaft.

Another solution of the object of the invention is to provide a rudder device for a ship, in particular a ship, with a rudder and a rudder stock as described above.

Another solution to the object of the invention is to provide a ship, in particular a ship, with a rudder stock as described above.

Another solution of the object of the invention is to provide a rudder stock trunk for the rudder stock described above, wherein the rudder stock trunk comprises at least one retainer element.

The retainer element may be formed according to the embodiments described above.

Another solution of the object of the invention is to provide a receiving shaft for a rudder stock as described above, wherein the receiving shaft has at least one complementary holder piece.

The complementary retainer work piece may be formed according to the embodiments described above.

Another solution of the object of the invention consists in a kit for a rudder stock as described previously, comprising at least one, in particular the previously described, holder element and comprising at least one, in particular the previously described, complementary holder piece, wherein the kit preferably comprises a rudder stock tube and/or a receiving shaft.

The rudder stock trunk and the receiving shaft can also be formed according to one of the embodiments described above.

Detailed Description

Fig. 1 shows a rudder stock 100 comprising a rudder stock trunk 10 and a receiving shaft 11. The rudder stock 100 is arranged in the hull 12 of the vessel 13. The hull 12 includes an outer side 14. The rudder stock trunk 10 is formed as a hollow pipe 15 and is inserted into the receiving shaft 11 from below in the vertical direction 16 from the outside 14 of the hull 12. In the state in which the rudder stock trunk 10 is arranged in the receiving shaft 11, an intermediate space 19 is formed between the outer wall 17 of the rudder stock trunk 10 and the inner wall 18 of the receiving shaft 11. The rudder stock 100 comprises a holder 20 for holding the rudder stock trunk 10 in the receiving shaft 11. The holder 20 comprises a holder element 21 which is attached to the outer wall 17 of the rudder stock trunk 10 in a material-bonded, form-fitting or force-fitting manner. Furthermore, the holder 20 comprises complementary holder pieces 22 which are arranged in a form-fitting, material-bonding or force-fitting manner on the inner wall 18 of the receiving shaft 11. Each complementary holder piece 22 protrudes in a radial direction 23 from the inner wall 18 of the receiving shaft 11 into the intermediate space 19. Likewise, each retainer element 21 protrudes from the outer wall 17 of the rudder stock trunk 10 into the intermediate space 19 in the radial direction 23. In the intermediate space 19, an adhesive 24 is furthermore present, which is designed as a cast plastic 25 and ensures that the rudder stock trunk 10 is firmly fixed in the receiving shaft 11. Furthermore, the rudder stock trunk 10 extends in the axial direction 26.

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

Fig. 2a shows a top view of the rudder stock trunk 10 and the receiving shaft 11 with respect to the axial direction 26. Fig. 2b shows a view of a complementary retainer piece 22 arranged on the inner wall 18 of the receiving shaft 11 and a retainer element 21 arranged on the outer wall 17 of the rudder stock tube 10 along the section line A-A in fig. 2 a.

The rudder stock trunk 10 comprises four retainer elements 21a to 21d which protrude from the outer wall 17 of the rudder stock trunk 10 into the intermediate space 19. On the inner wall 18 of the receiving shaft 11 four complementary holder 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 at even intervals along the outer circumference of the rudder stock tube 10 or along the inner circumference of the receiving shaft 11. As shown in fig. 2b, the

complementary holder pieces

22 or 22a to 22d are designed as profile bodies 29, in particular U-shaped profile bodies 28. The U-shaped profile body 28 comprises a tab 30 and a base 31. The

retainer element

21 or 21a to 21d is designed as a rod 32 and rests on a base 31 of a

complementary retainer piece

22 or 22a to 22d formed as a U-shaped profile body 28. By placing the rod 32 on the base 31 of the U-shaped profile body 28, the rudder stock tube 10 is hindered or prevented from moving downwards in the axial direction 26. The tabs 30 of the U-shaped profile body 28 also act as rotation stops 33. The rudder stock tube 10 shown in fig. 2a and 2b can therefore only be rotated slightly in the receiving shaft 11 before the bars 32 of the holder elements 21a to 21d strike the wings 30 of the U-shaped profile body 28. In fig. 2a, the intermediate space 19 between the rudder stock trunk 10 and the receiving shaft 11 is not filled. Thus, the rudder stock trunk 10 can be aligned or adjusted within the receiving shaft 11. For this purpose, a spacer element 34 as shown in fig. 2b may be provided. By arranging the spacer element 34 between the stem 32 and the base 31 of the U-shaped profile body 28, the rudder stock tube 10 can be adjusted in the receiving shaft 11. Fig. 2c and 2d show the possibility of adjusting the rudder stock trunk 10 in the receiving shaft 11. Thus, as shown in fig. 2c, the rudder stock trunk 10 can be moved laterally in the receiving shaft 11 such that the central axis 35 of the rudder stock trunk 10 is offset laterally with respect to the central axis 36 of the receiving shaft 11. Fig. 2d shows in a very exaggerated manner that by arranging the spacer element 34 between the holder element 21 and the complementary holder piece 22, the angle α between the central axis 35 of the rudder stock pipe 10 and the central axis 36 of the receiving shaft 11 can be adjusted. After alignment, the intermediate space 19 may be filled with an adhesive 24, in particular a cast plastic 25. After the adhesive 24 has hardened, the rudder stock trunk 10 is fixed in the receiving shaft 11.

In order to produce the rudder stock according to fig. 1 to 2d, a rudder stock tube is inserted into the receiving shaft 11 from the outer side 14 of the hull 12 in the vertical direction 16 (fig. 1). For this purpose, as shown in fig. 3, the rudder stock tube 10 is rotated relative to the receiving shaft 11 such that the retainer elements 21a to 21d and the complementary retainer 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 retainer elements 21a to 21d are guided past the complementary retainer pieces 22a to 22d until the retainer elements 21 to 21d are arranged above the complementary retainer pieces 22a to 22 d. Subsequently, the retainer elements 21a to 21d can be aligned with the retainer elements 22a to 22d by rotating the rudder stock tube 10 around the central axis 35 of the rudder stock tube 10, as shown in fig. 2 a. Subsequently, the rudder stock tube 10 can be moved downwards in the axial direction 26 or in the vertical direction 16, so that the holder elements 21a to 21d, in particular the holder elements 21a to 21d formed as bars 32, are arranged at complementary holder pieces 22a to 22d, in particular those holder pieces 22a to 22dss formed as U-shaped profile bodies 28. By arranging the retainer elements 21a to 21d at the complementary retainer pieces 22a to 22d, a retainer 20 is formed which prevents or counteracts a movement of the rudder stock trunk in the axial direction 26 (fig. 1) within the receiving shaft 11. The rudder stock trunk 10 can then be aligned, in particular with respect to the propeller axis or the stern tube. In order to fix the rudder stock trunk 10 in the receiving shaft, the intermediate space 19 is then filled with adhesive 24.

Another embodiment of the retainer 20 is shown in fig. 4. With the embodiment of fig. 1 and 2a, the embodiment according to fig. 4 differs only in that the

retainer element

21 or 21a to 21d is designed as a rod 32 which protrudes in the radial direction 23 into the intermediate space 19 between the rudder stock tube 10 and the receiving shaft 11 and is inclined upwards with respect to the axial direction 26. This leads to the fact that by moving the rudder stock tube 10 in the radial direction 23 in the receiving shaft 11, the

retainer elements

21 or 21a to 21d in the

complementary retainer piece

22 or 22a to 22d designed as a U-shaped profile body 28 receive an additional component of the movement in the axial direction 26 or counter to the axial direction 26 due to the tilting. Thus, the central axis 35 of the rudder stock trunk 10 is aligned with the central axis 36 of the receiving shaft 11.

Fig. 5a and 5b show another embodiment of the holder 20. Fig. 5a and 5b show a possible embodiment of the holder 20 using clamping elements. The holder element 21 in the rudder stock trunk 10 is formed as a recess 37, in particular a groove 38. The recess 37 is formed circumferentially around the rudder stock trunk 10. The complementary holder piece 22 is designed as a clamping element in the form of a clamping ring 39 and is arranged at the receiving shaft 11 in a form-fitting manner 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 fig. 5b, a gap 41 is included somewhere, which allows the clamping ring 39 to widen. When inserting the rudder stock trunk 10 into the receiving shaft 11, the clamping ring 39 is first widened so that the rudder stock trunk 10 can be guided through the clamping ring 39. Once the recess 37 or groove 38 of the rudder stock tube 10 is arranged on the level of the clamping ring 39, the clamping ring 39 is loosened so that the clamping ring 39 is inserted into the recess 37 and groove 38 of the rudder stock tube 10 as shown in fig. 5 a. This prevents the rudder stock trunk 10 from moving in the receiving shaft 11 in the axial direction 26 of the rudder stock trunk 10. Instead of the clamping ring 39 and the groove 38, other clamping elements and appropriately formed retainer elements 21 can also be used as complementary retainer pieces 22, which create a force-fit and/or form-fit clamping between the rudder stock pipe 10 and the receiving shaft 11.

Furthermore, in fig. 1, a sealing element 42 is shown 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-penetration 44, wherein the adhesive 24, in particular the cast plastic 25, can be introduced into the intermediate space 19 between the rudder stock trunk 10 and the receiving shaft 11 through the through-penetration 44. After the adhesive 24 hardens, the sealing sleeve 43 may remain on the outer side 14 of the hull 12. Alternatively, the sealing sleeve 43 may be removed from the outer side 14 of the hull 12.

Fig. 6 and 7 show another rudder stock 100. The rudder stock 100 comprises a receiving shaft 11 arranged on the hull 12 of a ship 13. The rudder stock trunk 10 is arranged in the receiving shaft 11 such that an intermediate space 19 is formed between the outer wall 17 of the rudder stock trunk 10 and the inner wall 18 of the receiving shaft 11. The rudder stock trunk 10 is arranged above 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 trunk 10 has a constant gap width 47. Above a lower region 46 of the clamping height 45, seen in the axial direction 26 of the hull 12, or in the vertical direction 16 of the rudder stock trunk 10, there is provided an intermediate region 48 in which the gap width 47 between the outer wall 17 of the rudder stock trunk 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 trunk 10 has a wall thickness 49 that decreases in an upward direction. In the upper region 50 of the clamping height 45, the retainer element 21 is arranged outside the rudder stock trunk 10. A corresponding complementary retainer work piece 22 is provided on the inner wall 18 of the receiving shaft 11. By means of the holder element 21 or the complementary holder workpiece 22, a reduction of the gap width 47 in the upper region 50 of the clamping height 45 is obtained. Instead of the holder element 21 and/or the complementary holder piece 22, a circumferential flange may also be provided. An adhesive 24, for example a cast plastic 25, is provided in the region of the holder element 21 and the complementary holder workpiece 22 in the upper region 50. Similarly, adhesive 24 is disposed within lower region 46 of gap width 47. The middle region 48 of the clamping level 45 is located between the upper region 50 and the lower region 46 of the clamping level 45, wherein the intermediate space 19 in the middle region 48 is not filled with adhesive 24.

In the perspective view of fig. 7, the increase in the gap width between the outer wall 17 of the rudder stock trunk 10 and the inner wall 18 of the receiving shaft 11 can be clearly seen. Furthermore, in the region of the constant gap width 47 in the lower region 46 and the holder element 21 or the complementary holder workpiece 22 in the upper region 50, an adhesive 24 is shown which is designed as a cast plastic 25.
