Description

Die Erfindung betrifft einen Keilverschluß für eine Rohrwaffe mit einem an einem Waffenrohr heckseitig angeordneten Bodenstück und einem in einer Ausnehmung des Bodenstückes senkrecht zur Seelenachse des Waffenrohres verschiebbaren Verschlußkeil.The invention relates to a wedge lock for a gun barrel with a rear side arranged on a weapon barrel bottom piece and a displaceable in a recess of the bottom piece perpendicular to the axis of the barrel axis weapon wedge.

Ein derartiger Keilverschluß ist beispielsweise aus der US 898,840 sowie aus der DE 198 23 785 A1 bekannt. Dabei weist der jeweilige Verschlußkeil an seinen gegenüberliegenden Seitenflächen, in Richtung der Seelenachse des Waffenrohres gesehen, mehrere hintereinander angeordnete sägezahnförmige Stufen auf, die in entsprechende Vertiefungen der Seitenwände der Ausnehmung des Bodenstückes eingreifen, so daß sich bei Schußabgabe die dem Waffenrohr abgewandten, als Anlageflächen ausgebildeten Seiten der Stufen des Verschlußkeiles an korrespondierenden Anlageflächen der Vertiefungen der Seitenwände des Bodenstückes abstützen. Die Anlageflächen der einzelnen Stufen des Verschlußkeiles und die Anlageflächen der korrespondierenden Vertiefungen der Seitenwände weisen bei den bekannten Keilverschlüssen im wesentlichen alle die gleiche Neigungsrichtung auf.Such a wedge lock is for example from the US 898,840 as well as from the DE 198 23 785 A1 known. In this case, the respective closure wedge on its opposite side surfaces, seen in the direction of the axis of the barrel axis, a plurality of successively arranged sawtooth-shaped steps, which engage in corresponding recesses of the side walls of the recess of the bottom piece, so that in firing the gun barrel facing away, trained as contact surfaces Support sides of the steps of the closure wedge on corresponding contact surfaces of the recesses of the side walls of the bottom piece. The contact surfaces of the individual stages of the closure wedge and the contact surfaces of the corresponding recesses of the side walls have in the known wedge closures substantially all the same direction of inclination.

Aus der US 5,014,592 ist ferner ein Keilverschluß bekannt, dessen Verschlußkeil drei sägezahnförmige Stufen aufweist, die derart in bezug auf die korrespondierenden Anlageflächen der Vertiefungen der Seitenwände des Bodenstückes angeordnet sind, daß bei Schußabgabe zunächst die Anlageflächen der beiden gegenüberliegenden heckseitigen Stufen des Verschlußkeiles an den korrespondierenden Anlageflächen des Bodenstückes anliegen und erst mit zunehmendem Druck auch die Anlageflächen der weiteren Stufen gegen die korrespondierenden Anlageflächen der Bodenstücke gepresst werden. Hierzu weisen die Anlageflächen der einzelnen nebeneinander angeordneten Stufen unterschiedliche Flankenwinkel auf, die allerdings mit dem Flankenwinkel der korrespondierenden Anlageflächen der Vertiefungen des Bodenstückes übereinstimmen. Bei diesem Verschlusskeil weist die erste Stufe eine positive Neigungsrichtung und die zweite Stufe eine negative Neigung (wenn man entlang der Seelenachse zur Mündung des Waffenrohres hin sieht) auf. Ferner offenbart die US 5,014,592 einen Verschlusskeil, an dem heckseitig ein in das Bodenstück einschiebbarer Steg befestigt ist, welcher die beiden Seiten des Bodenstückes (Bodenstückwangen) miteinander verbindet und bei Schussabgabe am Aufweiten hindert.From the US 5,014,592 Furthermore, a wedge lock is known, the closure wedge having three sawtooth-shaped steps, which are arranged with respect to the corresponding contact surfaces of the recesses of the side walls of the bottom piece, that initially abut the contact surfaces of the two opposite rear-side steps of the closure wedge on the corresponding contact surfaces of the bottom piece at firing and only with increasing pressure and the contact surfaces of the other stages against the corresponding contact surfaces of the bottom pieces are pressed. For this purpose, the contact surfaces of the individual juxtaposed stages have different flank angles, which, however, coincide with the flank angle of the corresponding contact surfaces of the depressions of the bottom piece. In this closure wedge, the first stage has a positive slope direction and the second stage has a negative slope (as seen along the axis of the soul towards the mouth of the barrel). Further, the US 5,014,592 a closure wedge, on the rear side of a insertable into the bottom piece web is attached, which connects the two sides of the bottom piece (bottom piece cheeks) together and prevents firing on firing.

Ein weiterer Verschluss ist aus der US 5,604,325 bekannt. Auch die DE 242 131 beschäftigt sich mit einem Verschlussblock, der aus zwei gegeneinander beweglichen Teilen besteht. In der US 2003051600 A1 wird vorgeschlagen, einen Verschlusskeil mit Hilfe auf eine Kolbenstange wirkende wiegenfeste Steuereinheit zu verschieben.Another closure is from the US 5,604,325 known. Also the DE 242 131 deals with a closure block, which consists of two mutually movable parts. In the US 2003051600 A1 It is proposed to move a closure wedge with the help of acting on a piston rod weighing control unit.

Ausgehend von der US 5,014,592 liegt der Erfindung die Aufgabe zugrunde, eine gegenüber bekannten Keilverschlüssen optimalere Kraftverteilung innerhalb des Bodenstückes bei Schussabgabe zu erreichen und damit die spannungsmäßige Höchstbelastung zu optimieren.Starting from the US 5,014,592 The invention has for its object to achieve a comparison with known wedge closures optimal power distribution within the bottom piece at firing and thus to optimize the maximum voltage stress.

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, einen Keilverschluss vorzusehen, dessen Verschlusskeil mindestens zwei axial hintereinander angeordnete Stufen aufweist, wobei die Anlagefläche der dem Waffenrohr benachbarten ersten Stufe eine positive und die Anlagefläche der zweiten Stufe eine negative Neigungsrichtung besitzen. Die Neigungsrichtungen der Anlageflächen der den Stufen korrespondierenden Vertiefungen der Seitenwände des Bodenstückes entsprechen den Neigungsrichtungen der Anlageflächen der beiden Stufen.The invention is essentially based on the idea to provide a wedge closure, the closure wedge has at least two axially successively arranged stages, wherein the contact surface of the gun barrel adjacent first stage has a positive and the contact surface of the second stage a negative slope direction. The inclination directions of the contact surfaces of the recesses corresponding to the steps of the side walls of the bottom piece correspond to the inclination directions of the contact surfaces of the two stages.

Als vorteilhaft hat es sich erwiesen, wenn die Neigungswinkel der Anlageflächen der Stufen des Verschlusskeiles zwischen 8 und 12° liegen.It has proven to be advantageous if the inclination angle of the contact surfaces of the steps of the closure wedge are between 8 and 12 °.

Bei einer Ausführungsform der Erfindung sind die Neigungswinkel der Anlageflächen der beiden Stufen des Verschlußkeiles und die Neigungswinkel der Anlageflächen der Vertiefungen derart gewählt, daß bei einer Schußabgabe zunächst die Anlageflächen der zweiten Stufe und der korrespondierenden Vertiefungen des Bodenstückes zur Anlage kommen und durch die elastische Verformung während der weiteren Belastung unter der Schußeinwirkung dann die Anlageflächen der ersten Stufe und der korrespondierenden Vertiefungen des Bodenstückes komplett flächenmäßig ganz zur Anlage kommen.In one embodiment of the invention, the inclination angle of the contact surfaces of the two stages of the closure wedge and the inclination angle of the contact surfaces of the wells chosen such that at a firing initially the contact surfaces of the second stage and the corresponding recesses of the bottom piece come to rest and then by the elastic deformation during the further load under the fire action the contact surfaces of the first Stage and the corresponding recesses of the bottom piece completely completely in terms of area come to rest.

Bei einer weiteren Ausführungsform der Erfindung sind die Seitenwände der Ausnehmung des Bodenstückes heckseitig fest über einen Steg miteinander verbunden, so daß bei Schußabgabe eine Aufweitung der Bodenstückwangen unmittelbar bei Krafteinleitung in die Wangen verringert wird. Dabei wird der Steg durch die Verwendung der negativen Neigung der Anlageflächen der zweiten Stufe und der korrespondierenden Anlageflächen der Vertiefung zugentlastet.In a further embodiment of the invention, the side walls of the recess of the bottom piece are firmly connected to each other at the rear end via a web, so that when wrenching an expansion of Bodenstückwangen is reduced immediately upon introduction of force into the cheeks. In this case, the web is relieved of strain by the use of the negative slope of the contact surfaces of the second stage and the corresponding contact surfaces of the depression.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden anhand von Figuren erläuterten Ausführungsbeispielen. Es zeigen:

  • Fig.1 eine perspektivische Ansicht des Bodenstückes einer großkalibrigen Waffe mit erfindungsgemäßem Keilverschluß ohne Verschlußkeil;
  • Fig.2 den für den in Fig.1 dargestellten Keilverschluß bestimmten Verschlußkeil und
  • Fig.3 einen vergrößerten Längsschnitt des in Fig.1 dargestellten Keilverschlusses mit Verschlußkeil vor einer Druckbelastung.
Further details and advantages of the invention will become apparent from the following with reference to figures explained embodiments. Show it:
  • 1 shows a perspective view of the bottom piece of a large-caliber weapon with wedge closure according to the invention without closure wedge;
  • Fig.2 for the wedge closure shown in Figure 1 certain wedge and
  • 3 shows an enlarged longitudinal section of the wedge closure shown in Figure 1 with closure wedge before a pressure load.

In Fig.1 ist mit 1 ein Waffenrohr bezeichnet, an dem heckseitig in an sich bekannter Weise ein Bodenstück 2 befestigt ist. Das Bodenstück 2 ist zum hinteren Ende hin gabelförmig ausgebildet und weist zwei Seitenteile (Bodenstückwangen) 3, 4 auf, welche mittels eines oberen Steges 5 oder eines (gestrichelt angedeuteten) unteren Steges 6 fest miteinander verbunden sind. Die Seitenteile 3, 4 und der Steg 5 oder 6 des Bodenstückes 2 begrenzen eine Ausnehmung 7, in welcher senkrecht zur Seelenachse 8 des Waffenrohres 1 ein Verschlußkeil 9 (Fig.2) verschiebbar anordbar ist.In Fig.1, 1 denotes a weapon barrel, on the rear side in a conventional manner, a bottom piece 2 is attached. The bottom piece 2 is fork-shaped towards the rear end and has two side parts (bottom piece cheeks) 3, 4 which are firmly connected to one another by means of an upper web 5 or a lower web 6 (indicated by dashed lines). The side parts 3, 4 and the web 5 or 6 of the bottom piece 2 define a recess 7, in which perpendicular to the axis of the soul 8 of the gun barrel 1, a closure wedge 9 (Figure 2) is displaceable arranged.

Der Verschlußkeil 9 weist auf jeder seiner Seiten 10, 11, in Richtung der Seelenachse 8 gesehen, zwei hintereinander angeordnete, seitlich vorstehende Stufen 12, 13 auf, die in entsprechende Vertiefungen 14, 15 der Seitenteile 3, 4 des Bodenstückes 2 eingreifen. Bei Schußabgabe stützen sich daher die dem Waffenrohr 1 abgewandten, als Anlageflächen 16, 17 ausgebildeten Seiten der Stufen 12, 13 des Verschlußkeiles 9 an korrespondierenden Anlageflächen 18, 19 der Vertiefungen 14, 15 der Seitenteile 3, 4 des Bodenstückes 2 ab. Dabei weisen die Anlageflächen 16 der dem Waffenrohr 1 benachbarten ersten Stufe 12 des Verschlußkeiles 9 und die Anlageflächen 18 der korrespondierenden ersten Vertiefungen 14 der Seitenteile 3, 4 jeweils eine positive Neigung mit den Neigungswinkeln α1 und β1 (in der Größenordnung von z.B. 10°) auf. Die Anlageflächen 17 der zweiten Stufe 13 des Verschlußkeiles 9 und die Anlageflächen 19 der korrespondierenden zweiten Vertiefungen 15 der Seitenteile 3, 4 weisen hingegen jeweils eine negative Neigung mit den Neigungswinkeln α2, und β2 (von z.B. ebenfalls ca. 10°) auf.The closure wedge 9 has on each of its sides 10, 11, viewed in the direction of the axis of the shaft 8, two successively arranged laterally projecting steps 12, 13, which engage in corresponding recesses 14, 15 of the side parts 3, 4 of the bottom piece 2. When firing, therefore, the gun barrel 1 facing away, as contact surfaces 16, 17 formed sides of the steps 12, 13 of the closure wedge 9 on corresponding contact surfaces 18, 19 of the recesses 14, 15 of the side parts 3, 4 of the bottom piece 2 from. In this case, the contact surfaces 16 of the weapon barrel 1 adjacent first stage 12 of the closure wedge 9 and the contact surfaces 18 of the corresponding first recesses 14 of the side parts 3, 4 each have a positive slope with the inclination angles α1 and β1 (in the order of eg 10 °) , The contact surfaces 17 of the second step 13 of the closure wedge 9 and the abutment surfaces 19 of the corresponding second depressions 15 of the side parts 3, 4, however, each have a negative inclination with the inclination angles α2, and β2 (for example also about 10 °).

Wie Fig.3 entnehmbar ist, unterscheiden sich die Neigungswinkel α1 und α2 der Anlageflächen 16, 17 der Stufen 12, 13 des Verschlußkeiles 9 und der Neigungswinkel β1 und β2 der Anlageflächen 18, 19 der Vertiefungen 14, 15 in dem dargestellten Ausführungsbeispiel, so daß im lastfreien Zustand zwischen den Anlageflächen 16, 17 der Stufen 12, 13 und den Anlageflächen 18, 19 der Vertiefungen 14, 15 jeweils nur ein linienförmiger Kontakt vorliegt. Erst mit zunehmender Last bei Schußabgabe werden dann die entsprechenden Anlageflächen 16, 17, 18, 19 der Stufen 12, 13 und Vertiefungen 14, 15 gleichmäßig gegeneinander gepreßt, so daß eine Linienanpressung bei Belastung vermieden wird und dadurch die Gefahr eines Verschleißes reduziert wird.As can be seen in FIG. 3, the angles of inclination α1 and α2 of the abutment surfaces 16, 17 of the steps 12, 13 of the closure wedge 9 and the inclination angles β1 and β2 of the abutment surfaces 18, 19 of the recesses 14, 15 differ in the illustrated embodiment, so that In the load-free state between the contact surfaces 16, 17 of the steps 12, 13 and the contact surfaces 18, 19 of the recesses 14, 15 there is only one linear contact. Only with increasing load at firing then the corresponding contact surfaces 16, 17, 18, 19 of the stages 12, 13 and depressions 14, 15 are uniformly pressed against each other, so that a Linienanpressung is avoided under load and thereby the risk of wear is reduced.

Ferner kann vorgesehen sein, daß die Anlageflächen 17 der zweiten Stufe 13 bei einer Belastung zuerst zur Anlage an die komplementäre Anlageflächen 19 der zweiten Vertiefung 15 des Bodenstückes 2 kommen und durch die elastische Verformung während der Weiterbelastung unter der Schußeinwirkung dann die Anlageflächen 16 der ersten Stufe 12 vollständig flächenmäßig zur Anlage an die komplementäre Anlageflächen 18 der ersten Vertiefung 14 des Bodenstückes 2 kommen.Furthermore, it can be provided that the contact surfaces 17 of the second stage 13 at a load first come to rest against the complementary contact surfaces 19 of the second recess 15 of the bottom piece 2 and by the elastic deformation during further loading under the fire action then the contact surfaces 16 of the first stage 12 completely flat in terms of contact with the complementary contact surfaces 18 of the first recess 14 of the bottom piece 2 come.
