Abstract

Die Erfindung betrifft ein gezogenes Waffenrohr (1), aus dem drallstabilisierte Geschosse (8) mit Führungsbändern (9) verschossen werden.
Zur Reduzierung von Verschleißerscheinungen an einem Führungsband (9) ist es bekannt, einen beim Verschuß auftretenden Drallwinkel (δ) zu stabilisieren oder in das Waffenrohr (1) tiefere Züge (3) in eine Rohrinnenwand (2) einzuarbeiten. Beide Möglichkeiten sind nur begrenzt umsetzbar, da die Kompatibiliät zwischen Waffenrohr (1) und Geschoß (8) gewährleistet sein muß.
Eine andere Möglichkeit der Verschleißreduzierung am Führungsband (9) sieht die vorgeschlagene Lösung vor. Durch eine Erhöhung der Anzahl der Züge (3) in der Rohrinnenwand (2) reduziert sich die auftretende Reibungsbelastung am Führungsband (9). Die neuartige Gestaltung von Zugflanken (5), die zwischen einem Zuggrund (7) des Zuges (3) und einem Feld (4) zwischen den Zügen (3) gebildet sind, reduziert das Gesamtverschleißvolumen des Führungsbandes (9). Dabei verlaufen die Zugflanken (5) fast senkrecht stehend zum Zuggrund (7).
