Description

Die Erfindung betrifft eine Kühleinrichtung für Revolvertrommeln von Revolverkanonen, wobei die Revolvertrommel mehrere Patronenlager aufweist und drehbar auf einer Trommelachse gelagert ist, und wobei in der Trommelachse ein Zuflusskanal vorgesehen ist, der mit im Bereich der einen Stirnseite der Revolvertrommel angeordneten radialen Eingangskanälen in Verbindung steht.The invention relates to a cooling device for revolver drums of revolver cannons, wherein the revolver drum has a plurality of cartridge bearings and is rotatably mounted on a drum axis, and an inflow channel is provided in the drum axis, which is connected to radial input channels arranged in the region of one end face of the revolver drum.

Bei Revolverkanonen wie beispielsweise aus einer Druckschrift OC 2059 e 94 der Firma Oerlikon-Contraves, Zürich, bekannt, wird im allgemeinen die beim Schiessen erwärmte Revolvertrommel durch die Umgebungsluft gekühlt. Bei längeren Feuerstössen und schneller Geschossfolge ist diese Kühlungsart jedoch ungenügend, da sich der Bereich der Trommel, in welchem das Geschoss im Patronenlager geführt wird, sehr stark erhitzen kann. Dadurch kann es bei Weiterleitung der Wärme in denjenigen Bereich der Trommel, in dem die Hülse im Patronenlager geführt wird zu einem kritischen Zustand kommen, so dass Sicherheits- und Zuverlässigkeitsprobleme wie z.B. Überdruckschüsse, Zündversager, Cook OFF usw. auftreten können.In the case of revolver cannons, for example from a publication OC 2059 e 94 from the company Oerlikon-Contraves, Zurich, the revolver drum heated during firing is generally cooled by the ambient air. In the case of longer bursts of fire and rapid projectile order, this type of cooling is insufficient, however, since the area of the drum in which the projectile is carried in the cartridge chamber can heat up considerably. This can lead to a critical condition when the heat is transferred to the area of the drum in which the sleeve is guided in the cartridge chamber, so that safety and reliability problems such as excess pressure shots, ignition failure, Cook OFF etc. can occur.

Mit der deutschen Patentschrift DE-PS 31 45 764 ist eine Kühleinrichtung für Waffenrohre von Feuerwaffen, insbesondere automatischen Feuerwaffen und Hochleistungsmaschinenkanonen bekannt geworden. Bei derartigen Hochleistungsfeuerwaffen, die hochgezüchtete Munition verfeuern, ist der hohe Waffenrohrverschleiss darauf zurückzuführen, dass die Oberflächenwärme nicht genügend schnell abgeführt wird. Die schnell aufeinanderfolgende Wärmebeaufschlagung beim Feuerstoss verursacht Oberflächenspannungen und Werkstoffumwandlungen. Durch das Flattern der Geschosse im Waffenrohr werden die Züge verformt, und es kommt zur Abtragung von Material durch das Führungsband der Geschosse. Um die Lebensdauer der Waffenrohre zu erhöhen wird mit vorstehend zitierter Patentschrift vorgeschlagen, im Bereich des axial an eine Trommel angrenzenden Endteiles des Waffenrohres in der Trommel radial nach aussen zwischen den einzelnen Patronenlagern ausgerichtete Kühlkanäle vorzusehen, die mit einem in der Trommelachse verlaufenden Hauptkanal für die Kühlmittelzuführung verbunden sind. Die Kühlkanäle sind mit parallel zur Trommelachse verlaufenden Düsen verbunden, die in die dem Waffenrohr zugewandte Stirnseite der Trommel einmünden und im gleichen Abstand zur Trommellängsachse wie die Mittellängsachsen der Patronenlager angeordnet sind. In den Kühlkanälen sind Absperrorgane für die Düsen vorgesehen, die im Falle des Beschusses jeweils diejenige Düse kurzzeitig freigeben, die sich im Bereich der Rohröffnung befindet. Die Absperrorgane sind z.B. Schieber, die mittels an einer Steuerkurve bei Drehbewegung der Trommel entlanggleitenden Steuerstücken verschoben werden können. Das Kühlmittel gelangt durch die Düsen direkt auf die Innenwandung des Waffenrohres im rückwärtigen Teil. Dabei sind die Düsen nur jeweils für den Zeitraum des Vorbeigleitens der Düsen im Waffenrohrrückteil geöffnet und die Kühlmittelzufuhr erfolgt nur dann, wenn geschossen wird.With the German patent DE-PS 31 45 764 a cooling device for gun barrels of firearms, in particular automatic firearms and high-performance machine guns, has become known. In high-performance firearms of this type, which fire highly-developed ammunition, the high level of wear on the weapon barrel is due to the fact that the surface heat is not dissipated quickly enough. The rapid succession of heat during the burst of fire causes surface tensions and material conversions. When the bullets flap in the weapon barrel, the trains are deformed and material is removed by the bullet's guide band. In order to increase the service life of the gun barrels, the patent cited above proposes to provide cooling channels in the region of the end part of the gun barrel axially adjacent to a barrel in the barrel, radially outward between the individual cartridges, with a main channel for the coolant supply running in the barrel axis are connected. The cooling channels are connected to nozzles running parallel to the drum axis, which open into the end of the drum facing the weapon barrel and are arranged at the same distance from the longitudinal axis of the drum as the central longitudinal axes of the cartridge chamber. Shut-off devices for the nozzles are provided in the cooling channels, which in the event of bombardment briefly release the nozzle in the area of the pipe opening. The shut-off devices are, for example, slides which can be moved by means of control pieces sliding along a control cam when the drum rotates. The coolant passes through the nozzles directly onto the inner wall of the barrel in the rear part. The nozzles are only open for the period when the nozzles slide past in the rear of the gun barrel and the coolant is only supplied when shooting.

Obwohl das Kühlmittel bei vorstehend beschriebener Kühleinrichtung für ein Waffenrohr durch die Trommel geführt wird, kann damit lediglich nur eine Kühlung im Bereich der Trommelstirnwand erreicht werden, so dass diese Einrichtung für die Beseitigung der eingangs genannten Probleme nicht geeignet ist.Although the coolant is passed through the drum in the case of the above-described cooling device for a weapon barrel, it is only possible to achieve cooling in the region of the drum end wall, so that this device is not suitable for eliminating the problems mentioned at the beginning.

Der Erfindung liegt die Aufgabe zugrunde eine Kühleinrichtung für eine Revolvertrommel der eingangs genannten Art vorzuschlagen, bei der die Erwärmung derart begrenzt wird, dass vorstehend erwähnte Nachteile vermieden werden.The invention has for its object to provide a cooling device for a revolver drum of the type mentioned, in which the heating is limited such that the above-mentioned disadvantages are avoided.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Erfindung gelöst. Hierbei sind jedem Patronenlager zwei parallel zur Trommelachse verlaufende Kühlkanäle zugeordnet, die sich über die ganze Länge der Geschossführung des Paronenlagers erstrecken. Die jeweils einem bestimmten Patronenlager zugeordneten Kühlkanäle sind an ihren Enden im Innern der Revolvertrommel miteinander verbunden. Im Bereich der einen Stirnseite der Revolvertrommel steht jeweils der erste von zwei einem Patronenlager zugeordneten Kühlkanälen über erste tangentiale Verbindungsrohre und die radialen Eingangskanäle mit dem in der Trommelachse vorgesehenen Zuflusskanal in Verbindung. Jeweils der zweite von zwei einem Patronenlager zugeordneten Kühlkanälen ist ebenfalls im Bereich der einen Stirnseite der Revolvertrommel über zweite tangentiale Verbindungsrohre und radiale, parallel zu den Eingangskanälen verlaufende Ausgangskanäle mit einem in der Trommelachse vorgesehenem Abflusskanal verbunden.This object is achieved by the invention specified in claim 1 . Each cartridge chamber is assigned two cooling channels that run parallel to the drum axis and extend over the entire length of the bullet guide of the block chamber. The cooling channels assigned to a particular cartridge chamber are connected to one another at their ends inside the revolver drum. In the area of the one end face of the revolver drum, the first of two cooling channels assigned to a cartridge chamber is connected via first tangential connecting tubes and the radial input channels to the inflow channel provided in the drum axis. In each case the second of two cooling channels assigned to a cartridge chamber is also connected in the region of one end face of the revolver drum via second tangential connecting pipes and radial outlet channels running parallel to the input channels with a drainage channel provided in the drum axis.

Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, dass das Kühlmittel nicht nacheinander durch alle Kühlkanäle der Revolvertrommel geführt wird, sondern dass jedem
Patronenlager ein eigener Kühlkreislauf zugeordnet ist, womit eine wirksame, die Wärme schnell abführende Kühlung erzielt wird. Ein weiterer Vorteil ist darin zu sehen, dass ein wesentlicher Teil der Wärme im am stärksten erhitzten Bereich, in welchem das Geschoss im Patronenlager geführt wird, schnell abgeführt wird. Dadurch kann sich der Bereich der Revolvertrommel, in dem die Hülse im Patronenlager geführt wird, nicht mehr so stark erwärmen.
Mit diesen Massnahmen werden die Beeinträchtigung der Kanonenfunktionen und festigkeitsmässige Probleme vermieden sowie der Spannungsverlauf in der Trommel verbessert.
Weitere Vorteile sind in den geringen Herstellungs- und Logistikkosten sowie im kleinen Änderungsaufwand an bestehenden Kanonen zu sehen.
The advantages achieved by the invention are, in particular, that the coolant is not passed through all the cooling channels of the revolver drum one after the other, but that everyone
Cartridge chamber is assigned its own cooling circuit, with which an effective, heat dissipating cooling is achieved. Another advantage can be seen in the fact that a substantial part of the heat is quickly dissipated in the most heated area, in which the projectile is guided in the cartridge chamber. As a result, the area of the revolver drum in which the sleeve is guided in the cartridge chamber can no longer heat up as much.
With these measures, the impairment of the cannon functions and strength problems are avoided and the tension curve in the drum is improved.
Further advantages can be seen in the low manufacturing and logistics costs as well as in the small change effort for existing cannons.

In den Fig. 1 bis 4 ist mit 1 eine Revolvertrommel bezeichnet, die drehbar auf einer Trommelachse 2 gelagert ist. Die Revolvertrommel 1 weist 4 Patronenlager 3 auf, die in eine Geschossführung 3.1 und eine Hülsenführung 3.2 unterteilt sind. Jedem Patronenlager 3 sind zwei parallel zur Trommelachse 2 verlaufende Kühlkanäle 4 zugeordnet, die sich über die ganze Länge der Geschossführungen 3.1 der Patronenlager 3 erstrecken und im Bereich zwischen dem betreffenden Patronenlager 3 und der Peripherie der Revolvertrommel 1 angeordnet sind. Die Kühlkanäle 4 sind an der einen Stirnseite 5 der Revolvertrommel 1 mittels Dichtstopfen 6 verschlossen. An ihren anderen Enden im Innern der Revolvertrommel 1 sind jeweils die einem bestimmten Patronenlager 3 zugeordneten Kühlkanäle 4 über tangential verlaufende Verbindungskanäle 7 miteinander verbunden. Die Öffnungen der Verbindungskanäle 7 münden in Ausnehmungen 8 der Revolvertrommel 1 und sind mit weiteren Dichtstopfen 9 verschlossen. Im Bereich der einen Stirnseite 5 der Revolvertrommel 1 ist jeweils der erste von zwei einem Patronenlager 3 zugeordneten Kühlkanälen 4 über erste tangential verlaufende Verbindungsrohre 10 mit Umlenkteilen 11 verbunden. Die Umlenkteile 11 stehen über radial verlaufende, um einen Winkel von 90° zueinander versetzte und zwischen den Patronenlagern 3 angeordnete Eingangskanäle 12 mit einem in der Trommelachse 2 vorgesehenen Zuflusskanal 13 in Verbindung. Am Ende des Zuflusskanals 13 sind vier um einen Winkel von 90° zueinander versetzte radiale Bohrungen 14 in der Trommelachse 2 vorgesehen, deren Achsen in der gleichen senkrecht zur Trommelachse 2 gerichteten Ebene wie die Achsen der Eingangskanäle 12 liegen. 1 to 4 , 1 denotes a revolver drum which is rotatably mounted on a drum axis 2 . The revolver drum 1 has 4 cartridge chambers 3 , which are divided into a projectile guide 3.1 and a sleeve guide 3.2 . Each cartridge chamber 3 are associated with two extending parallel to the drum axis 2 cooling channels 4, which extend over the whole length of the floor guides 3.1 of the cartridge chamber 3 and are arranged in the region between the respective cartridge chamber 3 and the periphery of the revolving drum. 1 The cooling channels 4 are closed on one end face 5 of the revolver drum 1 by means of sealing plugs 6 . At their other ends inside the revolver drum 1 , the cooling channels 4 assigned to a specific cartridge chamber 3 are connected to one another via tangentially extending connecting channels 7 . The openings of the connecting channels 7 open into recesses 8 of the revolver drum 1 and are closed with further sealing plugs 9 . In the region of one end face 5 of the revolving drum 1 is respectively connected to deflecting parts 11 of the first of two a cartridge chamber 3 associated cooling channels 4 extending through first tangential connecting pipes 10th The deflecting parts 11 are connected to an inlet channel 13 provided in the drum axis 2 via radial inlet channels 12 which are offset by an angle of 90 ° to one another and arranged between the cartridge bearings 3 . At the end of the inflow channel 13 there are four radial bores 14 offset from one another by an angle of 90 ° in the drum axis 2 , the axes of which are in the same plane perpendicular to the drum axis 2 as the axes of the input channels 12 lie.

Im Bereiche der einen Stirnseite 5 der Revolvertrommel 1 ist jeweils der zweite von zwei einem Patronenlager 3 zugeordneten Kühlkanälen 4 über zweite tangential verlaufende Verbindungsrohre 15 mit den Umlenkteilen 11 verbunden. Die Umlenkteile 11 stehen über radial und parallel zu den Eingangskanälen 12 verlaufende Ausgangskanäle 16 mit einem in der Trommelachse 2 vorgesehenen Abflusskanal 17 in Verbindung. Der Abflusskanal 17 ist durch ein Zwischenstück 18 vom Zuflusskanal 13 getrennt. Am Anfang des Abflusskanals 17 sind vier, um einen Winkel von 90° zueinander versetzte radiale Bohrungen 19 in der Trommelachse 2 vorgesehen, deren Achsen in der gleichen senkrecht zur Trommelachse 2 gerichteten Ebene wie die Achsen der Ausgangskanäle 16 liegen. Mit 20 ist eine Dichtungshülse bezeichnet, in der auf der Trommelachse 2 aufliegende Dichtungsringe 21 gehalten werden, so dass ein in den Kühlkanälen befindliches Kühlmittel nicht austreten kann.In the region of one end face 5 of the revolving drum 1 is respectively connected to the deflecting parts 11 of the second of two a cartridge chamber 3 associated cooling channels 4 extending via second tangential connecting pipes 15 °. The deflecting parts 11 are connected to an outlet channel 17 provided in the drum axis 2 via outlet channels 16 which run radially and parallel to the inlet channels 12 . The outflow channel 17 is separated from the inflow channel 13 by an intermediate piece 18 . At the beginning of the discharge channel 17 there are four radial bores 19 offset from one another by an angle of 90 ° in the drum axis 2 , the axes of which lie in the same plane directed perpendicular to the drum axis 2 as the axes of the output channels 16 . 20 denotes a sealing sleeve in which sealing rings 21 resting on the drum axis 2 are held so that a coolant located in the cooling channels cannot escape.

Die vorstehend beschriebene Kühleinrichtung arbeitet wie folgt:
Das Kühlmittel wird über den Zuflusskanal 13, die vier Bohrungen 14, die vier Eingangskanäle 12 und die vier ersten Verbindungsrohre 10 allen ersten Kühlkanälen 4 (4', Fig. 3) der Patronenlager 3 gleichzeitig zugeführt und von allen zweiten Kühlkanälen 4 (4'', Fig. 3) der Patronenlager 3 über die vier zweiten Verbindungsrohre 15, die vier Ausgangskanäle 16, die vier Bohrungen 19 und den Abflusskanal 17 gleichzeitig wieder abgeführt. Auf diese Weise wird jedes Patronenlager 3 separat und gleichzeitig mit den anderen gekühlt, so dass eine schnelle und wirkungsvolle Kühlung erzielt wird.
The cooling device described above works as follows:
The coolant is supplied via the inflow channel 13 , the four bores 14 , the four input channels 12 and the four first connecting pipes 10 to all the first cooling channels 4 ( 4 ', FIG. 3 ) of the cartridge chamber 3 and from all second cooling channels 4 ( 4 '' 3 ) the cartridge chamber 3 is simultaneously removed again via the four second connecting tubes 15 , the four outlet channels 16 , the four bores 19 and the drain channel 17 . In this way, each cartridge chamber 3 is cooled separately and simultaneously with the others, so that rapid and effective cooling is achieved.
