Description

The present invention relates to a rowing coker for a watercraft, comprising a coker pipe, a receiving shaft and a holder for holding the coker pipe in the receiving shaft, with a gap being provided between the coker pipe and the receiving shaft when the coker pipe is arranged in the receiving shaft. The present invention also relates to a watercraft with a rudder trunk, a trunk pipe for a rudder trunk, a receiving shaft for a rudder trunk and a kit for a rudder trunk.

Technological background

For the storage of large oars, for example in merchant ships or container ships, so-called oar cokers are used in the prior art. The rudder trunk of a rudder system is used to store the rudder stock and to transfer the rudder forces into the watercraft. In the state arranged on the ship, a rudder trunk comprises a receiving shaft, which is arranged in the hull, and a coker pipe, which is arranged in the receiving shaft. The coker pipe can be fixed in the receiving shaft by welding or gluing. The rudder stock is inserted into the coker tube fixed in the receiving shaft and stored there with axial and radial bearings.

From the EP 2 583 892 A1 by the same applicant is known a glued-in rowing coker, a coker tube being arranged in a receiving shaft and wherein an intermediate space is provided between a first part of the coker tube and a wall of the receiving shaft, the intermediate space being at least partially filled with a connecting means, the connecting means being a Means for gluing is.

In the prior art, the coker pipe is installed overhead in the receiving shaft in the hull. The aft section of the ship, in which the rudder trunk is arranged, is usually turned upside down by 180 ° when building ships, i.e. with the upper deck facing down. Therefore, the coker tube of the rudder coker is inserted into the aft section from above. Only after the rudder coker has been arranged and completed is the aft section rotated into an upright position, that is, with the upper deck facing up, and connected to the hull, the hull comprising the propeller and the stern tube. The alignment of the coker tube in the receiving shaft has therefore been independent of the actual propeller axis or the stern tube.

For hydrodynamic efficiency, however, it is advantageous if the rudder coker or the coker tube of the rudder coker, and thus the rudder, is aligned or adjusted with respect to the actual propeller axis or the actual stern tube of the ship. With the known installation methods for coker tubes without the possibility of being able to refer to an actual propeller axis or a stern tube, such an adjustment or alignment can only be carried out indirectly and with great effort.

Presentation of the invention: task, solution, advantages

The present invention is based on the object of providing a rudder trunk for a watercraft, which can be produced easily and inexpensively and which can be installed in the hull when the aft section is already connected to the hull, so that the rudder trunk, in particular the trunk tube, compared to the actual Propeller axis or the actual stern tube can be aligned or adjusted to improve hydrodynamic efficiency.

A further object of the present invention is to provide a watercraft with a rudder trunk, a trunk pipe for a rudder trunk, a receiving shaft for a rudder trunk and a kit for a rudder trunk, with which the aforementioned advantages are achieved.

To solve the problem underlying the invention, a rowing coker for a watercraft is proposed, comprising a coker pipe, a receiving shaft and a holder for holding the coker pipe in the receiving shaft, with an intermediate space being provided between the coker pipe and the receiving shaft when the coker pipe is in the receiving shaft wherein the holder comprises at least one holder element and at least one holder complement, wherein the at least one holder element is arranged on the coker pipe, wherein the at least one holder complement is arranged on the receiving shaft, and wherein the at least one holder element and / or the at least one holder complement in the state of the coker pipe arranged in the receiving shaft protrudes into the space.

The rudder trunk according to the invention for a watercraft comprises a trunk pipe and a receiving shaft. The receiving shaft is intended to be installed in a watercraft, in particular in an aft section of a watercraft, or the receiving shaft is already in the watercraft arranged. The coker pipe can be arranged in the receiving shaft to form a rowing coker, or the coker pipe is already arranged in the receiving shaft. Furthermore, a rudder stock can be arranged in the coker tube when the coker tube is attached to the hull in the receiving shaft.

When the coker pipe is arranged in the receiving shaft, a gap is provided between the coker pipe and the receiving shaft, in particular between an outer wall of the coker pipe and an inner wall of the receiving shaft. The interspace is preferably formed over its entire circumference between the outer wall of the coker pipe and the inner wall of the receiving shaft. The at least one holder element arranged on the coker pipe and / or the at least one holder complement arranged on the receiving shaft protrudes into the gap. The holder element and holder complement form a holder for holding the coker pipe in the receiving shaft.

By holding the coker pipe in the receiving shaft by means of the bracket comprising the at least one holder element and the at least one holder complement, it is possible to insert the coker pipe into the receiving shaft installed or to be built into the hull, in particular on the aft section of the watercraft, if the aft section is already connected to the Hull is connected, that is, when the upper deck of the ship, in particular the aft section, is directed upwards and the keel of the hull is directed downwards, whereas in the prior art the installation of the coker pipe in the receiving shaft in the hull takes place overhead, that is when the aft section of the ship, in which the rudder trunk is arranged, is turned 180 ° upside down, i.e. with the upper deck facing downwards.

In contrast to the installation methods known from the prior art, the coker pipe of the row coker according to the invention can be inserted into the receiving shaft from below and held in the receiving shaft. Since the stern section in particular is already connected to the hull when the coker tube is inserted into the receiving shaft from below, the coker tube held by the bracket can be aligned with the actual propeller axis or the actual stern tube of the watercraft.

The hydrodynamic efficiency can thus be improved compared to the row coker known from the prior art.

The protrusion of the at least one holder element and / or the at least one holder complement into the gap in the state of the coker pipe arranged in the receiving shaft provides a space-saving design of the holder for holding the coker pipe in the receiving shaft, since no further elements of the holder have to be arranged outside the receiving shaft .

If necessary, however, alignment aids can be provided for aligning the coker pipe in the receiving shaft inside and / or outside the receiving shaft, with which the coker pipe can be held in an alignment position for the alignment and later fixing of the coker pipe. However, the alignment aids are preferably removed again after alignment and fixation.

After the alignment or adjustment of the coker tube in the receiving shaft with respect to the actual propeller axis or the actual stern tube, the gap can be filled with a connecting means, preferably in areas, in order to fix the coker tube in the receiving shaft.

Another advantage of the rudder coker according to the invention is that the holder remains in the rudder trunk after connecting or after fixing the coker tube and therefore forces can also be dissipated via the holder. For example, in the event of failure of the connecting means, protection against sagging or slipping of the coker pipe can be provided.

It is preferably provided that the at least one holder element and the at least one holder complement can be arranged and / or arranged on one another in a non-positive and / or form-fitting manner, so that in the state of the coker pipe arranged in the receiving shaft, in particular in a state of the row coker pipe arranged on the watercraft, comprising coker pipe and Receiving shaft, a movement of the coker pipe in the receiving shaft in an axial direction of the coker pipe is hindered or prevented.

Due to the non-positive and / or positive arrangement of the holder complement and holder element, in particular when the rowing coker is arranged on the watercraft, comprising coker pipe and receiving shaft, the coker pipe can be held in the receiving shaft in an installation situation with the hull facing downwards with the keel. In this case, the non-positive and / or positive-locking arrangement of the holder element and prevents or prevents Holder complement a movement of the coker tube in an axial direction of the coker tube, in particular a movement of the coker tube downward out of the receiving shaft is prevented. In other words, the coker pipe cannot slip in the receiving shaft along its axial direction, in particular not in the downward axial direction. This enables the coker tube to be adjusted relative to the actual propeller axis or the actual stern tube of the watercraft before the coker tube is fixed in the receiving shaft.

With a further advantage it can be provided that at least two, preferably at least three, more preferably at least four, especially preferably exactly four, holder elements are provided, and / or that at least two, preferably at least three, more preferably at least four, especially preferably exactly four, Holder complements are provided

If at least two holder elements or at least two holder complements are provided, these can preferably be arranged opposite one another with respect to a central axis of the coker pipe or the receiving shaft on the outer wall of the coker pipe or on the inner wall of the receiving shaft. A two-point mounting of the coker pipe in the receiving shaft is provided by a force-fitting and / or positive-locking arrangement of these holder elements and holder complements, which allows pivoting or displacement of the coker pipe in the receiving shaft for aligning or adjusting the coker pipe. With at least three holder elements and three holder complements, a particularly advantageous three-point mounting is guaranteed. It is particularly advantageous if four holder elements and four holder complements are provided. In this case, the coker pipe is held in a particularly stable manner in the receiving shaft.

With a further advantage it can be provided that the at least one holder element is formed in one piece with the coker pipe and / or is connected to the coker pipe with a material fit and / or non-positive fit and / or a positive fit, and / or that the at least one holder complement is formed in one piece with the receiving shaft and / or is materially and / or non-positively and / or positively connected to the receiving shaft.

The material connection of the holder element with the coker pipe or of the holder complement with the receiving shaft can be produced, for example, by welding or gluing.

If the at least one holder element and / or the at least one holder complement is non-positively and / or positively connected to the coker tube and / or the receiving shaft, this connection can be made by inserting the holder elements or the holder complements into corresponding receptacles in the outer wall of the coker tube or in the inner wall of the receiving shaft. The positive and / or non-positive connection can also be made possible by the provision of fastening elements such as screws, bolts, adhesives, clamps, etc.

With a further advantage it can be provided that the at least one holder element and / or the at least one holder complement is a pin or a bolt, preferably a threaded bolt, or a projection or a plate or a web or a profile body, preferably a U-profile body, and / or that the at least one holder element and / or the at least one holder complement has a receptacle, in particular a bore 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, and / or that the at least one holder element and / or the at least one holder complement is a clamping element, in particular a clamping ring.

The at least one holder complement and the at least one holder element can be configured differently or identically. In a preferred embodiment, the holder element is designed in the form of a pin, a bolt, a projection, a plate or a web. The pin, the bolt, the projection, the plate or the web then protrude approximately in a radial direction from the outer wall of the coker tube. In contrast, the holder complement can be designed as a profile body, preferably as a U-profile body, which has a support surface, the profile body, preferably the U-profile body, protruding approximately in a radial direction into the interior of the receiving shaft from the inner wall of the receiving shaft .

If the holder complement is designed as a U-profile body and the holder element as a pin, bolt, projection, plate or web, the holder element can be hooked into the U-profile body. For this purpose, the holder element is inserted between the legs of the U-profile body and placed on a base section of the U-profile body. In this embodiment, twisting of the coker pipe in the receiving shaft can also be prevented or restricted, since the holder element designed as a pin, bolt, plate, web or projection strikes the legs of the U-profile body when attempting to twist the coker pipe. Due to the interaction of the holder element and A rotation brake is provided to the holder complement.

In principle, it is also possible that the holder element on the coker tube is designed as a U-shaped profile body, while the holder complement on the receiving shaft is designed as a pin, bolt, projection, plate or web. With both options, you only have to pay attention to the alignment of the U-profile body.

If the U-profile body is arranged on the receiving shaft as a holder complement, the legs of the U-profile body in the receiving shaft must be aligned upwards in a vertical direction so that the holder element of the coker tube, which is designed as a pin, bolt, projection, plate or web, enters the U from above -Profile body can be used.

If, on the other hand, the U-profile body is arranged as a holder element on the coker pipe, the legs of the U-profile body on the coker pipe must be aligned downwards in a vertical direction so that the U-profile body from above onto the pin, bolt, projection, plate or web Holder complement of the receiving shaft can be placed. The terms “vertical direction”, “up” and “down” relate to the condition of the coker pipe in the receiving shaft that is arranged on the watercraft.

In addition to these preferred embodiments, however, other configurations of the holder element and holder complement are also possible.

Either the holder element or the holder complement can be a threaded bolt. The corresponding holder complement or the corresponding holder element is then designed as a receptacle, in particular as a bore, preferably with an internal thread. The threaded bolt can be screwed into the receptacle or in the bore with the internal thread. By defining the screw-in depth, the coker pipe can be aligned or adjusted in the receiving shaft, in particular in a 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 coker pipe. The holder complement can be designed as a clamping element, in particular as a clamping ring, which is more preferably also arranged in a groove in the inner wall of the receiving shaft. If the coker pipe is inserted into the receiving shaft, the clamping element, designed as a holder complement, can engage both in the recess on the coker pipe and in the recess, in particular in the groove, of the receiving shaft and thereby favor a form-fitting and / or non-positive holding of the coker pipe in the receiving shaft or to ensure. In principle, however, the holder complement designed as a clamping element and the corresponding holder element can also be designed differently from a clamping ring and a recess, as long as the clamping element and the corresponding holder element together cause a non-positive and / or positive clamping between the coker pipe and the receiving shaft.

Another possibility is that the holder element and / or the holder complement are designed as a thread, an external thread being provided on the coker pipe and an internal thread being provided in the receiving shaft. In this case, the coker pipe can be screwed into the receiving shaft, with the holder elements and holder complements designed as internal and external threads providing a positive and non-positive connection. With a suitable design of the thread, in particular the pitch of the thread, the coker tube can still be moved in the receiving shaft so that it can be aligned on the watercraft with the actual propeller axis and the actual stern tube. A fixation of the coker pipe with connecting means in the receiving shaft can take place after the alignment.

With a further advantage, it is provided that the at least one holder element and the at least one holder complement protrude into the space between the coker tube and the receiving shaft, the at least one holder complement and / or the at least one holder element in relation to the respective radial direction with respect to the coker tube or the receiving shaft in Are arranged inclined in the direction of the axial direction of the coker pipe or the receiving shaft.

When the receiving shaft and the coker pipe are arranged on the hull of the ship, the holder elements and / or the holder complements are then preferably oriented slightly inclined downwards and / or upwards. Due to this slight inclination in the axial direction, a particularly advantageous alignment and adjustment of the coker pipe in the receiving shaft can be ensured. If, for example, two U-profile bodies are arranged opposite one another in the receiving shaft as holder complements, with the legs of the U-profile bodies pointing upwards, and the course of the U-profile bodies in the radial direction in the interior of the receiving shaft having a slight downward slope and, in contrast, two Bolt arranged as holder elements on an outer wall of the coker pipe, so the bolts can be in the U-profile body can be used from above in order to establish a positive and non-positive connection or bracket. If the coker pipe is now aligned, that is to say in particular a central axis of the coker pipe is aligned with respect to a central axis of the receiving shaft, this can be done by moving the coker pipe approximately in a radial direction in the receiving shaft. One of the bolts is then guided slightly downwards along the U-profile body, which is inclined slightly downwards, while the other bolt in the second U-profile body is guided slightly upwards. As a result, the central axis of the coker pipe is inclined with respect to the central axis of the receiving shaft. A corresponding effect also occurs with at least three or at least four or exactly four holder elements or holder complements.

With a further advantage it can be provided that the at least two holder elements are arranged, preferably uniformly, over an outer circumference of the coker pipe, and / or that the at least two holder complements are arranged, preferably uniformly, over an inner circumference of the receiving shaft.

A uniform arrangement of holder elements and holder complements enables simple production and simple alignment and adjustment of the coker pipe in the receiving shaft.

It is advantageously provided that the at least two holder elements are arranged spaced apart in the circumferential direction over the outer circumference of the coker pipe, and / or that the at least two holder complements are arranged spaced apart in the circumferential direction over the inner circumference of the receiving shaft, such that when the coker pipe is inserted into the receiving shaft, the Holder elements can be moved past the holder complements in the axial direction.

When the receiving shaft is arranged on the hull, in particular on the aft section, and the aft section or the hull is aligned with the keel down, the coker pipe can be inserted into the receiving shaft from below. The holder elements are guided past the holder complements of the receiving shaft and can then be brought into a positive and / or non-positive mutual arrangement with the holder complements, which preferably hinders or prevents a movement of the coker tube against the insertion direction.

It is particularly advantageous that the coker tube can be rotatably arranged and / or arranged in the receiving shaft when the space is not filled, so that the at least one holder element and the at least one holder complement are aligned with one another in the axial direction by rotating the coker tube can.

Furthermore, it can advantageously be provided that the coker pipe can be arranged and / or arranged movably in the axial direction in the receiving shaft if the intermediate space is not filled so that the at least one holder element can be arranged on the, in particular aligned, at least one holder complement, and / or so that the at least one holder element can be placed on the, in particular aligned, at least one holder complement.

It is particularly advantageous that the rotatable arrangement of the coker pipe enables the holder elements to be aligned with one another by rotating the coker pipe after the holder elements have been guided past the holder complements when the coker pipe is inserted into the receiving shaft from below before the holder elements and holder complements are arranged be aligned with the holder complements. The manner of operation of the holder provided in this way resembles a bayonet lock.

When the coker tube is inserted into the receiving shaft from below, the coker tube is first aligned so that the holder elements can be guided past the holder complements. As soon as the holder elements are located above the holder complements, the coker tube can be rotated so that the holder elements are aligned with the holder complements as viewed in the axial direction of the coker tube or the receiving shaft. The coker tube can then be moved downwards in the axial direction, the holder elements entering into a form-fitting and / or force-locking connection with the holder complements and holding the coker tube in the receiving shaft.

It can advantageously be provided that the coker pipe in the state arranged in the receiving shaft, in particular in a state of the rowing coker arranged on the watercraft, comprising the coker pipe and the receiving shaft, further particularly if the space is not filled, can be adjusted, in particular aligned, in the receiving shaft.

The adjustment of the coker tube arranged in the receiving shaft can thus take place particularly advantageously in the state arranged on the watercraft, that is to say in relation to an actual propeller shaft or in relation to an actual stern tube. The adjustment is preferred, if the space has not yet been filled with a lanyard. However, it can also be carried out when the space is preferably filled in areas with a connecting means. If the connecting means is a cast plastic, an alignment or adjustment can take place while the cast plastic is hardening.

The coker pipe can preferably be displaced in the interior of the receiving shaft for alignment and adjustment with respect to a radial direction of the receiving shaft.

Adjustment means can be provided with further advantage, the adjustment means being designed so that, in particular with holder elements and holder complements arranged next to one another, a position and / or alignment of the coker pipe in the receiving shaft, in particular the position of the coker pipe in the receiving shaft with respect to a radial direction of the receiving shaft and / or an angle between a central axis of the coker pipe and a central axis of the receiving shaft can be adjusted.

The adjustment means can be additional elements, but the adjustment means can also be part of the holder elements and / or the holder complements. For example, it is possible for the holder elements and / or the holder complements to be adjustable. In a preferred embodiment, an angle of inclination of the holder elements and / or the holder complements can be set.

With a further advantage it can be provided that the adjusting means are adjusting screws and / or washers, preferably washers, the adjusting means preferably being arranged on the at least one holder element and / or on the at least one holder complement.

It is preferably provided that the space between the outer wall of the coker pipe and the inner wall of the receiving shaft expands or decreases at least in some areas in the axial direction of the coker pipe. In other words, a gap in the space between the outer wall of the coker tube and the inner wall of the receiving shaft increases or decreases at least in some areas in the axial direction of the coker tube. Particularly preferably, the gap dimension of the space between the outer wall of the coker tube and the inner wall of the receiving shaft increases at least in some areas in the axial direction of the coker tube upwards, i.e. when the rowing coker or the receiving shaft is arranged on the watercraft, in particular on the ship, in the direction of the watercraft body , in particular the hull, too.

The increase in the size of the gap can take place in that the inside diameter of the receiving shaft increases at least in some areas in the direction of the hull when it is arranged on the ship, and / or that the outside diameter of the coker pipe decreases in at least some areas in the direction of the hull when it is arranged on the ship. Particularly preferably, a wall thickness of the coker pipe decreases as seen in the axial direction of the coker pipe, the inside diameter of the coker pipe remaining constant in the axial direction and the outside diameter decreasing.

When the coker pipe is arranged in the receiving shaft, the coker pipe is arranged over a clamping height in the receiving shaft. The clamping height is preferably formed between a lower end or an outer side of the receiving shaft and an upper region, in particular an upper end, of the coker pipe. The gap dimension preferably increases at least in regions over the course of the clamping height. A lower region of the clamping height can particularly preferably have a constant gap dimension. To increase the gap size in areas, it increases above the area of the constant gap size.

Furthermore, viewed in the axial direction, the gap dimension can decrease again in an upper region of the clamping height. The decrease in the gap dimension in the upper region of the clamping height can be caused by the holder complements and / or holder elements of the holder protruding into the space. Furthermore, the decrease in the size of the gap in the upper area of the clamping height can also take place by means of a, in particular circumferential, flange on the inner wall of the receiving shaft or the outer wall of the coker pipe in the upper area.

In principle, however, it is also conceivable that the size of the gap between the outer wall of the coker tube and the inner wall of the receiving shaft, at least in some areas in the axial direction of the coker tube, is downward, i.e. when the row coker or the coker is arranged on the watercraft, in particular the ship Receiving shaft in the direction facing away from the watercraft body, in particular from the hull of the ship.

With a further advantage it can be provided that the intermediate space can be filled or filled at least in some areas with a connecting means, preferably with a cast plastic, in particular cast resin.

The gap is filled with the connecting means, in particular the cast plastic, preferably only after the alignment and adjustment of the coker pipe in the receiving shaft, at least partially filled. As soon as the connecting means establish a firm connection between the coker pipe and the receiving shaft, for example as soon as the cast plastic has hardened, a fixed and aligned or adjusted coker pipe is obtained in the receiving shaft, which provides a particularly high hydrodynamic efficiency. In addition, the holder elements and holder complements that preferably continue to remain in the intermediate space prevent the coker pipe from slipping even if the connecting means fails, for example if the cast plastic leaks.

Particularly preferably, the gap is only filled with the connecting means in the lower region of the clamping height with a constant gap dimension. Alternatively or additionally, the intermediate space can also be filled with the connecting means only in the upper region of the clamping height, in particular in the region of the holder element and / or the holder complement and / or the flange. Particularly preferably, the gap in the area of the widening gap dimension is not filled with the connecting means.

With a further advantage, it can be provided that a sealing element, in particular a sealing sleeve, is provided, the sealing element resting against an outside of the rowing coker so that when the space is filled, the connection means can be prevented from leaking to the outside through the sealing element, wherein preferably the sealing element, can be removed especially after the space has been filled.

When the rudder coker is arranged on the watercraft, the outside of the rudder coker corresponds to the outside of the ship's hull, specifically preferably to the area of the ship's hull which surrounds the outside opening of the receiving shaft. When the receiving shaft is arranged on the ship, the coker pipe can be inserted into the receiving shaft from below. A sealing element, in particular a sealing sleeve, is then attached to the outside of the ship's hull and thus to an outside of the rudder coker, which seals the space between the coker tube and the receiving shaft from below. After the sealing element has been attached, the space between the coker tube and the receiving shaft can be filled with a connection means, in particular with a cast plastic, the sealing element allowing the connection means to escape from the space, in particular downwards to the outside of the rudder coker or to the outside of the hull , prevented. After the space has been filled with the connecting means, the sealing element can remain on the hull or on the outside of the rudder coker. However, it is also possible for the sealing element to be removed after the space has been filled with the connecting means. If the sealing element remains on the hull or on the outside of the rudder coker, further protection against leakage of the connecting means, in particular the cast plastic, is offered. If, however, the sealing element is removed, it can be reused.

It is provided with a further advantage that the sealing element is designed in one piece, in particular in one piece, or in several pieces.

A multi-part design of the sealing element allows the sealing element to be attached particularly easily to the outside of the rudder coker or to the outside of the hull.

With a further advantage it can be provided that the sealing element comprises an, in particular ring-shaped, frame and / or an O-ring and / or an elastomer.

Another advantage is provided if the sealing element has at least one opening, in particular an opening or a passage, it being possible through the opening to introduce the connecting means, in particular into the space.

If the sealing element is arranged on the outside of the rudder coker or on the outside of the hull in the area of the rudder coker, the connecting means can be introduced into the space from the outside of the watercraft into the space through the opening, in particular through the opening or the passage. This provides a particularly simple way of filling the space.

The openings can be designed to be closable in order to prevent the connecting means, in particular the cast plastic, from escaping after the space has been filled. Furthermore, hoses for introducing the connecting means can be passed through the openings. This can prevent the formation of bubbles in the connecting means, in particular in the cast plastic.

It is provided with a further advantage that the connecting means, in particular the cast plastic, can be liquefied, preferably through the introduction of heat, so that the coker pipe after liquefaction the connecting means can be removed from the receiving shaft.

If the connecting means, in particular the cast plastic, is designed to be liquefiable by the introduction of heat, replacement of the coker pipe is simplified. If it should be necessary to replace the coker pipe, the connecting means can be liquefied by the introduction of heat. The coker pipe can then be removed from the receiving shaft on the hull. For this purpose, in a preferred embodiment, the coker pipe must be raised in the vertical direction after the connecting means has liquefied, so that the coker pipe moves upwards in the receiving shaft. The coker pipe is then rotated so that the holder elements and holder complements that were previously aligned with one another are rotated with respect to one another. The coker pipe can then be guided out of the receiving shaft in the axial direction downwards, the holder elements being guided past the holder complements. A new coker pipe can then be inserted.

It is provided with a further advantage that heating elements, in particular heating wires, are arranged in the intermediate space and are preferably embedded in the connecting means.

By providing heating elements, in particular heating wires, replacement of the coker pipe is further simplified. The heating elements, in particular the heating wires, allow homogeneous thermal energy to be introduced into the connecting means for the exchange, so that it liquefies evenly.

With a further advantage it can be provided that recesses, in particular grooves or bores, are arranged on the outside and / or on the inside of the coker pipe and / or the receiving shaft, with signal conducting means, in particular cables, preferably being arranged in the recesses.

For sensors to be attached to the rudder trunk or to the trunk tube or to the receiving shaft or to the rudder shaft, grooves or bores can be provided in the trunk tube or in the receiving shaft in order to guide corresponding signal conducting means, such as cables, therein. The signal conducting means can preferably be guided in the space between the coker pipe and the receiving shaft and, with further advantage, be led out at the least stressed points of the receiving shaft or the coker pipe.

It is preferably provided that the holder elements arranged next to one another, in particular the bolts or webs, and holder complements, in particular the profile bodies or U-profile bodies, restrict or prevent rotation of the coker pipe when rotational or torsional forces act on the coker pipe.

The holder elements and holder complements thus preferably represent rotation brakes. This further improves the introduction of force from the rudder stock into the hull. In particular, if the holder complements are designed as U-profile bodies and if the holder elements are designed as bolts, pins, projections, webs or plates, which are arranged between the legs of the holder complements designed as U-profile bodies, twisting of the coker pipe in the receiving shaft is prevented . However, a slight twist may be permitted. This can be done when the distance between the legs of the U-profile body is greater than the width of the holder elements arranged between the legs. Due to the low permissible rotatability, manufacturing tolerances can be compensated for when aligning the coker pipe in the receiving shaft.

Another solution to the problem on which the invention is based is to provide a rudder arrangement for a watercraft, in particular a ship, with a rudder and a rudder trunk as described above.

Another solution to the problem on which the invention is based is to provide a watercraft, in particular a ship, with a rudder trunk as described above.

An additional solution to the problem on which the invention is based is to provide a coker pipe for a previously described rowing pipe, the coker pipe having at least one holder element.

The holder element can be designed in accordance with the embodiments described above.

Yet another solution to the problem on which the invention is based consists in providing a receiving shaft for a previously described rowing trunk, the receiving shaft having at least one holder complement.

The holder complement can be designed in accordance with the embodiments described above.

Yet another solution to the problem on which the invention is based consists in a kit for a previously described rudder trunk comprising at least one, in particular previously described, holder element and comprising at least one, in particular previously described, holder complement, wherein the kit preferably comprises a coker pipe and / or a receiving shaft.

Detailed description of the figures

1 shows a rowing trunk 100 comprising a coker pipe 10 and a receiving slot 11 . The rowing coker 100 is in a ship's hull 12th of a watercraft 13 arranged. The hull 12th has an outside 14th on. The coker pipe 10 is here as a hollow tube 15th formed and in a vertical direction 16 from the outside 14th of the hull 12th from below into the slot 11 introduced. Between the outer wall 17th of the coker pipe 10 and the inner wall 18th of the receiving slot 11 is in the slot 11 arranged state of the coker pipe 10 a gap 19th educated. The rowing coker 100 includes a bracket 20th to hold the coker pipe 10 in the receiving slot 11 . The bracket 20th includes holder elements 21st which on the outside wall 17th of the coker pipe 10 are firmly bonded, positively or non-positively attached. The holder also includes 20th Holder complements 22nd which on the inside wall 18th of the receiving slot 11 Are arranged positively, cohesively or positively. Each of the holder complements 22nd protrudes in a radial direction 23 from the inner wall 18th of the receiving slot 11 in the space 19th inside. Each of the holder elements also protrudes 21st from the outside wall 17th of the coker pipe 10 in the radial direction 23 in the space 19th inside. There is also a space in between 19th a lanyard 24 , which as cast plastic 25th is designed and for a secure fixation of the coker pipe 10 in the receiving slot 11 cares. The coker pipe 10 also extends in an axial direction 26th .

In the 2a and 2 B is a first embodiment of the bracket 20th shown.

2a shows a plan view of the coker pipe 10 and the receiving slot 11 against the axial direction 26th . 2 B Figure 13 shows a view of that on the inner wall 18th of the receiving slot 11 arranged holder complement 22nd and that on the outside wall 17th of the coker pipe 10 arranged holder element 21st along the section line AA 2a .

The coker pipe 10 has four holder elements 21a to 21d on which from the outside wall 17th of the coker pipe 10 in the space 19th protrude. On the inside wall 18th of the receiving slot 11 are four holder complements 22a to 22d arranged, which also in the space 19th protrude. The holder elements 21a to 21d and the holder complements 22a to 22d are even over the outer circumference of the coker pipe 10 or over the inner circumference of the receiving shaft 11 spaced apart. How out 2 B can be seen are the holder complements 22nd or. 22a to 22d as a profile body 29 and especially as a U-profile body 28 educated. The U-profile body 28 wise thighs 30th as well as a base section 31 on. The holder elements 21st or. 21a to 21d are used as bridges 32 formed and on the base portion 31 as a U-profile body 28 trained holder complements 22nd or. 22a to 22d is filed. By resting the bars 32 on the base section 31 the U-profile body 28 becomes a movement of the coker pipe 10 in the axial direction 26th hindered or prevented downwards. The thigh 30th of the U-profile body 28 also serve as a rotation brake 33 . This is how the coker pipe 10 in the in the 2a and 2 B shown arrangement only slightly in the receiving shaft 11 rotate before the bars 32 the holder elements 21a to 21d on the thighs 30th the U-profile body 28 nudge. In the 2a is the space in between 19th between the coker pipe 10 and the receiving slot 11 not completed. Accordingly, the coker pipe 10 in the receiving slot 11 be aligned or adjusted. For this, the 2 B Shown washer elements 34 be provided. By arranging the washers 34 between the jetty 32 and the base section 31 of the U-profile body 28 can the coker pipe 10 in the receiving slot 11 adjusted. In 2c and 2d are the options for adjusting the coker pipe 10 in the receiving slot 11 shown. As in 2c the coker pipe 10 such in the receiving shaft 11 laterally shifted that the central axis 35 of the coker pipe 10 opposite the central axis 36 of the receiving slot 11 is laterally offset. In 2d is shown greatly exaggerated that by arranging washers 34 between the holder elements 21st and the holder complements 22nd an angle α between the central axis 35 of the coker pipe 10 and the central axis 36 of the receiving slot 11 can be adjusted. After the alignment has taken place, the gap 19th with a lanyard 24 , especially with a cast plastic 25th , fill out. After the lanyard has hardened 24 is the coker pipe 10 in the receiving slot 11 fixed.

For the production of the rowing coker according to the 1 to 2d gets the coker pipe from the outside 14th of the hull 12th in the vertical direction 16 ( 1 ) into the slot 11 introduced. For this, as in 3 shown the coker pipe 10 opposite the receiving slot 11 rotated so that the holder elements 21a to 21d and the holder complements 22a to 22d are not aligned with one another. In this position the coker pipe 10 in the vertical direction 16 like this in the receiving shaft 11 are introduced that the holder elements 21a to 21d on the holder complements 22a to 22d are passed until the holder elements 21a to 21d above the holder complements 22a to 22d are arranged. The holder elements 21a to 21d by turning the coker pipe 10 around the central axis 35 of the coker pipe 10 with the holder elements 22a to 22d be aligned, as in the supervision in 2a shown. Then the coker pipe 10 in the axial direction 26th or against the vertical direction 16 be moved down, so that, in particular as webs 32 trained, holder elements 21a to 21d to, especially as a U-profile body 28 trained, holder complements 22a to 22d to be ordered. By the arrangement of the holder elements 21a to 21d on the holder complements 22a to 22d becomes a bracket 20th formed which allows movement of the coker tube in the axial direction 26th inside the receiving slot 11 prevented or disabled ( 1 ). Then the coker pipe 10 , in particular on a propeller axis or on a stern tube. For fixing the coker pipe 10 The space is then in the receiving shaft 19th with a lanyard 24 filled out.

In 4th is another embodiment of the bracket 20th shown. Compared to the design of the 1 and 2a the embodiment differs according to 4th only in that they act as webs 32 trained holder elements 21st or. 21a to 21d which in the radial direction 23 in the space 19th between the coker pipe 10 and the receiving slot 11 protrude, in addition against the axial direction 26th are inclined upwards. This leads to that by moving the coker pipe 10 in the receiving slot 11 in the radial direction 23 the holder elements 21st or. 21a to 21d in the U-profile body 28 trained holder complements 22nd or. 22a to 22d due to the inclination an additional component of the movement in or against the axial direction 26th receive. This becomes the central axis 35 of the coker pipe 10 opposite the central axis 36 of the receiving slot 11 aligned.

Another embodiment of the bracket 20th is in 5a and 5b shown. When designing the 5a and 5b it is a possible formation of the bracket 20th using a clamping element. The holder element 21st in the coker pipe 10 is as a recess 37 , especially as a groove 38 , educated. The recess 37 is about the coker pipe 10 formed all around. The holder complement 22nd is as a clamping element in the form of a clamping ring 39 formed and form-fitting over an inner wall 18th of the receiving slot 11 circumferential second groove 40 on the receiving slot 11 arranged. The clamping ring 39 is not completely closed, but demonstrates 5b a crack at one point 41 on which allows the clamping ring 39 can be expanded. When inserting the coker pipe 10 into the slot 11 is then first of all the clamping ring 39 to widen so that the coker pipe 10 through the clamping ring 39 can be performed. Once the recess 37 or the groove 38 of the coker pipe 10 at the height of the clamping ring 39 is arranged, the clamping ring 39 relaxed, so that, as in the 5a shown in the recess 37 or the groove 38 of the coker pipe 10 intervenes. This causes a movement of the coker pipe 10 in the axial direction 26th of the coker pipe 10 in the receiving slot 11 prevented. Instead of the clamping ring 39 and the groove 38 can be used as a holder complement 22nd also other clamping elements and suitably designed holder elements 21st be used, which have a non-positive and / or positive locking between the coker pipe 10 and receiving slot 11 cause.

In 1 is also a sealing element 42 shown which one on the outside 14th of the hull 12th is arranged. The sealing element 42 is as a sealing collar 43 formed and has an opening 44 on through which the lanyard 24 , especially the cast plastic 25th in the space 19th between the coker pipe 10 and the Receiving slot 11 can be initiated. After the lanyard has hardened 24 can the sealing sleeve 43 either on the outside 14th of the hull 12th remain. Alternatively, it is possible that the sealing collar 43 from the outside 14th of the hull 12th Will get removed.

The 6th and 7th show another rowing trunk 100 . The rowing coker 100 has a receiving slot 11 on which on a ship's hull 12th of a watercraft 13 is arranged. A coker pipe 10 is in the slot 11 arranged such that between the outer wall 17th of the coker pipe 10 and the inner wall 18th of the receiving slot 11 a gap 19th is trained. The coker pipe 10 is about a clamping height 45 in the receiving slot 11 arranged. In a lower area 46 the clamping height 45 indicates the gap 19th between the inner wall 18th of the receiving slot 11 and the outer wall 17th of the coker pipe 10 a constant gap 47 on. In the axial direction 26th up towards the hull 12th or in the vertical direction 16 of the coker pipe 10 seen is above the lower range 46 the clamping height 45 a middle area 48 provided in which the gap dimension 47 between the outer wall 17th of the coker pipe 10 of the inner wall 18th of the receiving slot 11 in the direction of the hull 12th increases. For increasing the gap size 47 points the coker pipe 10 a wall thickness that decreases towards the top 49 on. In an upper area 50 the clamping height 45 are on the outside of the coker pipe 10 Holder elements 21st arranged. On the inside wall 18th of the receiving slot 11 are corresponding holder complements 22nd arranged. Through the holder elements 21st or holder complements 22nd there is a decrease in the gap size 47 in the upper area 50 the clamping height 45 . Instead of the holder elements 21st and / or the holder complements 22nd a circumferential flange can also be provided. In the upper area 50 in the area of the holder elements 21st and holder complements 22nd is a lanyard 24 such as cast plastic 25th , arranged. Likewise is in the lower area 46 constant gap 47 a lanyard 24 intended. Between the upper area 50 and the lower area 46 the clamping height 45 is the middle area 48 the clamping height 45 , where the space 19th in the middle area 48 not with a lanyard 24 is filled out.

In the perspective view of the 7th is the increasing gap between the outer wall 17th of the coker pipe 10 and the inner wall 18th of the receiving slot 11 clearly visible. In addition, are in the lower area 46 constant gap 47 as well as in the upper area 50 in the area of the holder elements 21st or holder complements 22nd as cast plastic 25th trained lanyard 24 shown.
