Abstract
Es wird vorgeschlagen, Kühlkanäle (3) auf der Umfangsoberfläche (2) der/des einzelnen Patronenlager(s) (1) zu fräsen. Dadurch, dass die Kühlkanäle (3) auf die frei zugängliche Oberfläche (2) gefräst werden, ist eine einfachere Fertigung möglich.It is proposed to mill cooling channels (3) on the peripheral surface (2) of the individual cartridge chamber (s) (1). The fact that the cooling channels (3) are milled on the freely accessible surface (2), a simpler production is possible.
Description
Die Erfindung betrifft ein Patronenlager mit Kühlkanälen.The The invention relates to a chamber with cooling channels.
Eine
Trommelwaffe ist beispielsweise aus der

der
Nachteilig ist, dass diese Kanäle und Verbindungsleitungen durch aufwendiges Tieflochbohren hergestellt werden, was auch unnötige Zugangsbohrungen einschließt. Diese werden bekanntlich mittels Stopfbuchsen dann geschlossen.adversely is that these channels and connecting lines through elaborate Deep hole drilling can be made, including unnecessary access holes includes. These are known by stuffing boxes then closed.
Hier greift die Erfindung die Aufgabe auf, eine andere Form der Schaffung der Kühlkanäle aufzuzeigen.Here the invention takes on the task of another form of creation show the cooling channels.
Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1.Solved the object is achieved by the features of patent 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.Of the The invention is based on the idea of drum cooling to adjust the geometry of the drum and the cooling channels on the surface of the individual cartridge chamber (s) too milling. Because of the cooling channels Milled on the freely accessible surface become, 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.Next the simplified production is created a better tightness. In addition, a higher number of cooling channels be provided. Also, the length of the channels variable designable. By a more even Distribution of the cooling channels can also be a better Cooling capacity 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 weapons or cannons whose cartridge chamber can be made from a separate part and which in a later manufacturing process into a weapon barrel or a modular revolver gun can be fitted.
Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigtBased an embodiment with drawing, the invention be explained in more detail. It shows
