Description

Die Erfindung betrifft eine Rohrwaffe, bei der das mit einem Bodenstück verbundene Waffenrohr in einem Wiegenrohr verschiebbar gelagert ist.The invention relates to a gun barrel, in which the gun barrel connected to a bottom piece is slidably mounted in a cradle tube.

DE 19 800 193 offenbart eine Rohrwaffe gemäß dem Oberbegriff des Anspruchs 1. DE 19 800 193 discloses a gun barrel according to the preamble of claim 1.

Eine derartige Rohrwaffe ist beispielsweise aus der DE 31 48 265 A1 bekannt. Dabei wird das Waffenrohr in zwei Gleitbuchsenlagern gelagert, die am mündungs- und am bodenseitigen Ende des Wiegenrohres angeordnet sind. Nachteilig ist bei einer derartigen bekannten Gleitbuchsenlagerung, daß das Waffenrohr, z.B. einer Panzerkanone, massebedingt auf dem unteren Lagerinnenrand aufliegt und sich durch die bei Schußabgabe auftretende Rohraufweitung hochhebt. Dieser Vorgang führt dann zu Schwingungen des Waffenrohres und wirkt sich negativ auf den Abgangsfehler des jeweiligen Geschosses aus.Such a tube weapon is for example from the DE 31 48 265 A1 known. In this case, the gun barrel is mounted in two sliding bush bearings, which are arranged at the mouth and at the bottom end of the cradle tube. The disadvantage of such a known Gleitbuchsenlagerung that the gun barrel, for example, a tank cannon, due to the mass rests on the lower inner edge of the bearing and lifts itself up by the tube expansion occurring at firing. This process then leads to vibrations of the barrel and has a negative effect on the departure error of each bullet.

Aus der DE 39 36 454 A1 ist es bekannt, zur Vermeidung der beim Abfeuern entstehenden Rohrschwingungen statt herkömmlicher Gleitbuchsenlager hubeffektfreie Lager zu verwenden, bei denen das Waffenrohr bei Schußabgabe in radialer Richtung gegen keinen festen Anschlag stößt, so daß sowohl in horizontaler wie in vertikaler Richtung eine Rohraufweitung erfolgen kann. Zur Lagerung des Waffenrohres in dem Wiegenrohr sind an dem Waffenrohr umfangseitig vier gleichmäßig verteilt angeordnete, sich in Richtung der Längsachse erstreckende und als Gleitschienen ausgebildete Führungsschienen vorgesehen, die in entsprechenden Führungsnuten des Wiegenrohres eingreifen, derart, daß die Richtungen der Auflagerkraft und der radialen Rohraufweitung jeweils senkrecht zueinander stehen.From the DE 39 36 454 A1 It is known to use instead of conventional Gleitbuchsenlager lifting effect-free bearing to avoid the resulting during firing pipe vibrations in which the gun barrel at firing in the radial direction against any fixed stop, so that both in the horizontal and vertical direction, a tube expansion can be done. For storage of the barrel in the cradle four circumferentially uniformly distributed, extending in the direction of the longitudinal axis and designed as slide rails guide rails are provided which engage in corresponding guide grooves of the cradle tube, such that the directions of the support force and the radial pipe expansion respectively perpendicular to each other.

Nachteilig ist bei dieser Lagerung vor allem, daß die Führungsschienen und Führungsnuten sich über beide Lagerstellen hinweg erstrecken und daher ein hoher fertigungstechnischer Aufwand erforderlich ist. Außerdem ist der Wechsel des Waffenrohres bei derartigen Rohrwaffen kompliziert und damit zeitaufwendig.The disadvantage of this storage, above all, that the guide rails and guide grooves extend over both bearing points away and therefore a high manufacturing technology Effort is required. In addition, the change of the gun barrel in such a pipe weapon is complicated and therefore time consuming.

Ausgehend von der DE 39 36 454 A1 liegt der Erfindung die Aufgabe zugrunde, eine in einem Wiegenrohr verschiebbar gelagerte Rohrwaffe anzugeben, bei der ein Hubeffekt des Waffenrohres weitgehend vermieden wird und bei der aufwendige Führungsnuten in dem Wiegenrohr nicht erforderlich sind sowie bei der ein Rohrwechsel wie bei herkömmlichen Waffenlagerungen möglich ist.Starting from the DE 39 36 454 A1 The invention has for its object to provide a slidably mounted in a cradle tube weapon, in which a lifting effect of the gun barrel is largely avoided and in the complex guide grooves in the cradle tube are not required and in which a tube change as in conventional weapon bearings is possible.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

Die Erfindung beruht im wesentlichen auf dem Gedanken, an dem Waffenrohr mindestens mündungsseitig, vorzugsweise aber auch heckseitig ein Gleitbuchsenlager anzuordnen, welches eine Rohrbuchse umfaßt, in der das Waffenrohr hubeffektfrei angeordnet ist und deren Außenflächen in dem Wiegenrohr formschlüssig gleitend (d.h. mit geringst möglichem Spiel) gelagert sind, so daß -anders als im Falle der DE 39 36 454 A1 - eine unabhängig voneinander wirkende axiale und radiale Gleitführung des Waffenrohres stattfindet. Dabei erfolgt die radiale Gleitführung des Waffenrohres bei Schußabgabe ähnlich wie im Falle der DE 39 36 454 A1 mittels leistenförmiger Vorsprünge, die in entsprechende nutenförmige Ausnehmungen der Rohrbuchse eingreifen und das Waffenrohr zentrisch in der Rohrbuchse halten. Ein radialer Aufweitungsausgleich erfolgt wiederum durch vorhandene Spielvorgabe zwischen Waffenrohr bzw. einem mit dem Waffenrohr drehfest verbundenen, die leistenförmigen Vorsprünge tragenden Innenring und der inneren Oberfläche der Rohrbuchse.The invention is based essentially on the idea of arranging at the mouth side at least mouth, but preferably also a sliding bush bearing, which comprises a pipe bushing in which the barrel is arranged Hubeffektfrei and their outer surfaces in the cradle tube form-fitting sliding (ie with the least possible game) are stored so that -anders than in the case of DE 39 36 454 A1 - An independently acting axial and radial sliding guide of the barrel takes place. In this case, the radial sliding of the gun barrel at firing is similar to the case of the DE 39 36 454 A1 by strip-shaped projections which engage in corresponding groove-shaped recesses of the pipe bushing and keep the barrel centrally in the pipe socket. A radial widening compensation takes place in turn by existing game specification between gun barrel or a non-rotatably connected to the gun barrel, the strip-shaped projections bearing inner ring and the inner surface of the pipe sleeve.

Aufgrund der fehlenden axialen Schienenführung ist ein gegenüber vergleichbaren Rohrwaffen geringerer Fertigungsaufwand erforderlich. Außerdem ist die vorgeschlagene Lagerung des Waffenrohres sehr robust und es ist ein einfacher Austausch vorhandener herkömmlicher Gleitbuchsen gegen die neuen, zentrisch führenden, genuteten Rohrbuchsen möglich.Due to the lack of axial rail guidance compared to comparable guns less manufacturing effort is required. In addition, the proposed storage of the gun barrel is very robust and it is a simple replacement of existing conventional sliding bushes against the new, centrically leading, grooved pipe bushings possible.

Um einen schnellen Waffenrohrwechsel im Felde durchführen zu können, hat es sich als vorteilhaft erwiesen, die Rohrbuchse des vorderen (ersten) Gleitbuchsenlagers fest mit dem Waffenrohr und die Rohrbuchse des hinteren (zweiten) Gleitbuchsenlagers fest mit dem Bodenstück zu verbinden. Beim Rohrwechsel bleibt dann die erste Rohrbuchse auf dem Waffenrohr und wird mit diesem demontiert. Die zweite Rohrbuchse verbleibt am Bodenstück zentrisch über seinen Außendurchmesser in der Wiege geführt.In order to be able to make a quick change of gun barrel in the field, it has proven to be advantageous to firmly connect the pipe bushing of the front (first) Gleitbuchsenlagers with the barrel and the pipe sleeve of the rear (second) Gleitbuchsenlagers with the bottom piece. When changing the tube then the first pipe bushing remains on the gun barrel and is dismantled with this. The second tube bushing remains centered on the bottom piece over its outer diameter in the cradle.

Sofern die Rohrbuchse des zweiten Gleitbuchsenlagers eine Länge aufweist, die derart gewählt ist, daß die Rohrbuchse bei einem Rücklauf des Waffenrohres vollständig aus dem Wiegenrohr herausgezogen wird, sollte in dem Wiegenrohr mündungsseitig vor dem hinteren Gleitbuchsenlager eine zusätzliche Gleitbuchse mit vorgegebenem Passungsspiel angeordnet werden, welche die Führung des Waffenrohres in diesem Falle übernimmt.If the pipe bushing of the second Gleitbuchsenlagers has a length which is chosen such that the pipe bushing is completely withdrawn at a return of the gun barrel from the cradle tube, should be arranged in the cradle muzzle before the rear Gleitbuchsenlager an additional sliding bush with predetermined Passungsspiel, which Leadership of the weapon barrel in this case takes over.

Das zweite Gleitbuchsenlager kann aber auch eine Länge aufweisen, die derart gewählt ist, daß die Rohrbuchse das Wiegenrohr beim Rücklauf nicht verläßt und somit auf eine zusätzliche Gleitbuchse verzichtet werden kann.However, the second Gleitbuchsenlager can also have a length which is chosen such that the pipe socket does not leave the cradle pipe during the return and thus can be dispensed with an additional slide bushing.

In Fig. 1 ist mit 1 eine Rohrwaffe bezeichnet, bei der das Waffenrohr 2 in einem Wiegenrohr 3 einer Wiege 4 axial verschiebbar gelagert ist. Hierzu sind am mündungsseitigen Ende des Wiegenrohres 3 ein erstes Gleitbuchsenlager 5 und am bodenstückseitigen Ende des Wiegenrohres 3 ein zweites Gleitbuchsenlager 6 angeordnet.In Fig. 1 1 denotes a gun barrel, in which the weapon barrel 2 is mounted axially displaceably in a cradle 3 of a cradle 4. For this purpose, a first plain bush bearing 5 and at the bottom end of the weighing tube 3, a second plain bush bearing 6 are arranged at the mouth-side end of the cradle tube 3.

Das erste Gleitbuchsenlager 5 umfaßt eine Rohrbuchse 7 (Fig.2 und 3), deren Außenfläche 8 gleitend in dem Wiegenrohr 3 gelagert ist, wobei zwischen der Rohrbuchse 7 und dem Wiegenrohr 3 ein möglichst geringes Passungsspiel vorhanden ist. Die Rohrbuchse 7 weist innenseitig vier gleichmäßig verteilt angeordnete, nutenförmige Ausnehmungen 9 auf, in die vier entsprechende, an dem Waffenrohr 2 befestigte leistenförmige Vorsprünge 10 eingreifen.The first slide bush bearing 5 comprises a pipe bushing 7 (FIG. Fig.2 and 3 ), whose outer surface 8 is slidably mounted in the cradle tube 3, wherein between the pipe sleeve 7 and the cradle tube 3 as small as possible match clearance is present. The pipe sleeve 7 has on the inside four evenly distributed, groove-shaped recesses 9, in the four corresponding, attached to the gun barrel 2 strip-shaped projections 10 engage.

Zwischen der äußeren Oberfläche 11 des Waffenrohres 2 und der inneren Oberfläche 12 der Rohrbuchse 7 sowie zwischen den Leistenköpfen 13 und der inneren Oberfläche 14 der nutenförmigen Ausnehmungen 9 der Rohrbuchse 7 ist jeweils ein vorgegebenes Spiel vorgesehen (in Fig.2 und 3 ist dieses Spiel durch einen dicken schwarzen Strich angedeutet).Between the outer surface 11 of the gun barrel 2 and the inner surface 12 of the pipe sleeve 7 and between the inguinal heads 13 and the inner surface 14 of the groove-shaped recesses 9 of the pipe sleeve 7 is a predetermined game is provided in each case (in Fig.2 and 3 this game is indicated by a thick black line).

Das zweite Gleitbuchsenlager 6 (Fig.1) ist ähnlich wie das erste Gleitbuchsenlager 5 aufgebaut und umfaßt ebenfalls eine das Waffenrohr 2 zentrisch führende genutete Rohrbuchse 15. Dabei ist die Rohrbuchse 15 in diesem Fall mit einem Bodenstück 16 verschraubt.The second sliding bush bearing 6 ( Fig.1 ) is similar to the first slide bush bearing 5 constructed and also includes a gun barrel 2 centric leading grooved pipe bushing 15. In this case, the pipe bushing 15 is bolted to a bottom piece 16.

Vor dem zweiten Gleitbuchsenlager 6 ist im Wiegenrohr 3 eine herkömmliche Gleitbuchse 17 mit vorgegebenem Passungsspiel angeordnet.Before the second Gleitbuchsenlager 6 a conventional bushing 17 is arranged with a predetermined fit clearance in the cradle tube 3.

Nachfolgend wird auf die Wirkungsweise der erfindungsgemäßen Rohrwaffe 1 und damit auch auf die Funktionsweise der Gleitbuchsenlager 5 und 6 eingegangen:Subsequently, the operation of the gun barrel 1 according to the invention and thus also on the operation of the sliding bush bearings 5 and 6 will be discussed:

Wird ein Geschoß aus der Rohrwaffe 1 abgefeuert, so weitet sich das Waffenrohr 2 bei dem Durchlauf des Geschosses durch das Waffenrohr 2 elastisch auf und die an dem Waffenrohr 2 vorgesehenen leistenförmigen Vorsprünge 10 verschieben sich radial innerhalb der nutenförmigen Ausnehmungen 9 in den Rohrbuchsen 7 und 15. Aufgrund des vorgegebenen Spiels zwischen Waffenrohr 2 und Rohrbuchsen 7, 15 bleiben die Rohrbuchsen 7, 15 unverformt und können über ihre gleitbeschichteten, zum Wiegeninnendurchmesser mit geringstem Spiel versehenen Außenflächen 8 axial verschoben werden, ohne daß ein Verklemmen innerhalb des Wiegenrohres 3 zu befürchten ist. Durch die gleichmäßige radiale Verschiebung der äußeren Waffenrohrwandung innerhalb des Gleitbuchsenlagers bleibt das Waffenrohr stets zentrisch geführt, so daß es während des Geschoßdurchlaufes zu keinem Hubeffekt mit seinen negativen Auswirkungen auf das Treffverhalten des Geschosses kommen kann.If a projectile fired from the gun 1, the gun barrel 2 expands elastically during the passage of the projectile through the gun barrel 2 and provided on the gun barrel 2 strip-shaped projections 10 move radially within the groove-shaped recesses 9 in the pipe sleeves 7 and 15th Due to the predetermined clearance between gun barrel 2 and pipe bushes 7, 15, the pipe bushings 7, 15 remain undeformed and can be axially displaced over their slippery, provided for cradle inner diameter with minimum clearance outer surfaces 8, without jamming within the cradle tube 3 is to be feared. Due to the uniform radial displacement of the outer gun barrel wall within the sliding sleeve bearing the weapon barrel always remains centered, so that it can come during the projectile run to no lifting effect with its negative impact on the meeting behavior of the projectile.

Das zweite mit dem Bodenstück 16 und dem Waffenrohr 2 verbundene Gleitbuchsenlager 6 läuft mit diesen Einheiten beim Rücklauf des Waffenrohres mit zurück, d.h., die zweite Rohrbuchse 6 verläßt zunächst das Wiegenrohr 3, um dann bei dem Vorlauf des Waffenrohres 2 über eine Einführschräge 18 (Fig.1) wieder in das Wiegenrohr 3 einzufädeln. Die Führung des Waffenrohres 2 wird nach Verlassen der spielarm geführten Rohrbuchse 15 von der davor sitzenden Gleitbuchse 17 übernommen. Gleitbuchse 17 und Waffenrohr 2 haben hierbei ein vorgegebenes relativ großes Spiel, um ein sicheres Einfädeln der Rohrbuchse 15 in das Wiegenrohr 3 zu erreichen und ein Verklemmen bei der Rohraufweitung beim Geschoßdurchlauf sicher zu vermeiden.The second sliding bush bearing 6 connected to the bottom piece 16 and the weapon barrel 2 runs back with these units during the return of the weapon barrel, ie, the second pipe bushing 6 first leaves the cradle 3, in order then to reach the lead pipe of the weapon barrel 2 via an insertion bevel 18 (FIG. Fig.1 ) to thread back into the cradle tube 3. The leadership of the gun barrel 2 is taken over after leaving the low-play pipe bushing 15 of the front seated bushing 17. Sliding bushing 17 and gun barrel 2 in this case have a predetermined relatively large game to achieve a safe threading the pipe sleeve 15 in the cradle tube 3 and to avoid jamming in the pipe expansion during projectile passage safely.

Die Fig.4 und 5 zeigen ein den Fig.2 und 3 entsprechendes zweites Ausführungsbeispiel eines ersten Gleitbuchsenlagers 5'mit einer Rohrbuchse 7'. Dabei sind allerdings die vier leistenförmigen Vorsprünge 10' nicht direkt an dem Waffenrohr 2' befestigt, sondern an einem mit dem Waffenrohr 2' drehfest und spielarm verbundenen Innenring 19. Die nutenförmigen Ausnehmungen der Rohrbuchse 7'sind mit 9' bezeichnet.The 4 and 5 show the one Fig.2 and 3 corresponding second embodiment of a first Gleitbuchsenlagers 5'mit a pipe bushing 7 '. However, the four strip-shaped projections 10 'are not directly attached to the gun barrel 2', but at one with the gun barrel 2 'rotatably and low-backlash connected inner ring 19. The groove-shaped recesses of the pipe sleeve 7' are designated by 9 '.

Zwischen dem Innenring 19 und einer mit 20 bezeichneten Rohrschulter (Fig.5) sitzt ein Haltering 21. Der Innenring 19 und der Haltering 21 werden mittels eines Konterringes 22, welcher über ein Gewinde 23 mit dem Waffenrohr 2' verschraubt ist, axial gehalten. Der Haltering 21 und der Konterring 22 bilden die axiale Begrenzung für die Rohrbuchse 7'. Außerdem verhindern zwei Verdrehsicherungen 24 ein Verdrehen der Rohrbuchse 7' um die Rohrachse 25.Between the inner ring 19 and a tube shoulder designated 20 ( Figure 5 ) is a retaining ring 21. The inner ring 19 and the retaining ring 21 are axially held by means of a lock ring 22 which is screwed via a thread 23 with the gun barrel 2 '. The retaining ring 21 and the lock ring 22 form the axial boundary for the pipe bushing 7 '. In addition, prevent two Verdrehsicherungen 24 twisting the pipe sleeve 7 'to the tube axis 25th

Fig.6 zeigt eine vergrößerte detailliertere Darstellung eines zweiten Gleitbuchsenlagers 6', welches im wesentlichen dem ersten Gleitbuchsenlager 5' entspricht und bei dem die nicht dargestellten leistenförmigen Vorsprünge ebenfalls auf einem an dem Waffenrohr 2' drehfest angeordneten Innenring 19' befestigt sind. Figure 6 shows an enlarged detailed representation of a second Gleitbuchsenlagers 6 ', which essentially corresponds to the first Gleitbuchsenlager 5' and in which the non-illustrated strip-like projections are also mounted on one of the gun barrel 2 'rotatably mounted inner ring 19'.
