Abstract

A cartridge/ammunition holder (1) has at least one cooling channel (3) mill-cut on the peripheral surface (2) of the cartridge holder (1).

Description

Die Erfindung betrifft ein Patronenlager mit Kühlkanälen.The invention relates to a chamber with cooling channels.

Eine Trommelwaffe ist beispielsweise aus der DE 195 01 003 C2 bekannt, ein Trommelrevolver aus der DE 196 24 400 A1 .A drum weapon, for example, from the DE 195 01 003 C2 known, a drum turret from the DE 196 24 400 A1 ,

Aus der EP 0 731 330 B1 ist eine Revolvertrommel einer Revolverkanone und einer Kühlvorrichtung bekannt. Ausgehend von der US 2,801,575 wird vorgeschlagen, Verbindungsrohre zwischen einzelnen Kühlkanälen einzubinden.From the EP 0 731 330 B1 a revolver drum of a revolver gun and a cooling device is known. Starting from the US 2,801,575 It is proposed to incorporate connecting pipes between individual cooling channels.

Nachteilig ist, dass diese Kanäle und Verbindungsleitungen durch aufwendiges Tieflochbohren hergestellt werden, was auch unnötige Zugangsbohrungen einschließt. Diese werden bekanntlich mittels Stopfbuchsen dann geschlossen.The disadvantage is that these channels and connecting lines are made by consuming deep hole drilling, which also includes unnecessary access holes. These are known to be closed by glands then.

Hier greift die Erfindung die Aufgabe auf, eine andere Form der Schaffung der Kühlkanäle aufzuzeigen.Here, the invention takes on the task to show a different form of creation of the cooling channels.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1.The problem is solved by the features of claim 1.

Der Erfindung liegt die Idee zugrunde, die Trommelkühlung an die Geometrie der Trommel anzupassen und die Kühlkanäle auf der Oberfläche der / des einzelnen Patronenlager(s) zu fräsen. Dadurch, dass die Kühlkanäle auf die frei zugängliche Oberfläche gefräst werden, entfallen die oben aufgezählten Nachteile.The invention is based on the idea to adapt the drum cooling to the geometry of the drum and to mill the cooling channels on the surface of the individual cartridge chamber (s). The fact that the cooling channels are milled onto the freely accessible surface eliminates the disadvantages enumerated above.

Neben der vereinfachten Fertigung wird eine bessere Dichtigkeit geschaffen. Zudem können eine höhere Anzahl Kühlkanäle vorgesehen werden. Auch ist die Länge der Kanäle variabler gestaltbar. Durch eine gleichmäßigere Verteilung der Kühlkanäle kann zudem eine bessere Kühlleistung bewirkt werden.In addition to the simplified production, a better tightness is created. In addition, a higher number of cooling channels can be provided. Also, the length of the channels is variable shaped. By a more uniform distribution of the cooling channels also a better cooling performance can be effected.

Die Lösung ist für alle Waffen bzw. Kanonen geeignet, deren Patronenlager aus einem separaten Teil gefertigt werden können und welche in einem späteren Fertigungsprozess in ein Waffenrohr oder eine modulare Revolverkanone eingepasst werden.The solution is suitable for all guns or cannons whose chamber can be made from a separate part and which are fitted in a later manufacturing process in a gun barrel or a modular turret gun.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt

Fig. 1
eine perspektivische Darstellung eines Patronenlagers,
Fig. 2
das Patronenlager aus Fig. 1 in einer Teilschnittdarstellung,
Fig. 3
eine Darstellung der Einfräsung.
Reference to an embodiment with drawing, the invention will be explained in more detail. It shows
Fig. 1
a perspective view of a cartridge chamber,
Fig. 2
the cartridge chamber Fig. 1 in a partial sectional view,
Fig. 3
a representation of the milling.

Fig. 1 als auch Fig. 2 zeigen eine stilistische Darstellung eines Patronenlagers 1 mit am Umfang bzw. auf der Umfangsoberfläche 2 eingefrästen Kühlkanälen 3, welche sich bevorzugt nur in einem Teilbereich des Patronenlagers 1 befinden. Diese Kühlkanäle 3 können in sich geschlossen oder aber auch als Einzelkanal 3.1 gewindeartig eingebracht sein. Fig. 1 as well as Fig. 2 show a stylistic representation of a cartridge chamber 1 with milled on the periphery or on the peripheral surface 2 cooling channels 3, which are preferably only in a portion of the cartridge chamber 1. These cooling channels 3 can be self-contained or can also be thread-like introduced as a single channel 3.1.

Dieses Patronenlager 1 kann Bestandteil einer nicht näher dargestellten Trommel mit mehreren Patronenlagern sein.This cartridge chamber 1 may be part of a drum not shown with several cartridge bearings.

In Fig. 3 dargestellt ist ein möglicher Verlauf der Einfräsungen am Umfang 2 des Patronenlagers 1 aus den Fig. 1 und 2.In Fig. 3 shown is a possible course of the milled recesses on the circumference 2 of the cartridge chamber 1 from the Fig. 1 and 2 ,
