Description

Einrichtung zum Auswechseln heiß gewordener Läufe bei Maschinengewehren Den Gegenstand der Erfindung bildet eine Einrichtung bei Maschinengewehren nach Patent 466 183 zum Auswechseln heiß gewordener Läufe.Device for replacing hot barrels in machine guns The subject of the invention is a device in machine guns Patent 466 183 for replacing hot barrels.

Die Befestigung von Geschützteilen mittels unterbrochener segmentartiger Gewinde ist bei Schraubenverschlüssen bereits bekannt. Ferner sind auchLaufbefestigungen fürRückstoßladepistolen bekannt geworden, bei welchen der Lauf mit Vorsprüngen versehen ist. die zum Eingriff mit entsprechend ausgebildeten Yuten oder Ausnehmungen des Gehäuses eingerichtet sind, wobei die Lösung der Befestigung durch Verdrehen des Laufes erfolgt.The attachment of gun parts by means of interrupted segment-like Thread is already known in screw closures. There are also barrel attachments has become known for recoil loading pistols in which the barrel is provided with projections is. to engage with appropriately designed yutes or recesses of the Housing are set up, the solution of the attachment by rotating the Run takes place.

Erfindungsgemäß ist der das Muttergewinde für das Laufgewinde enthaltende Teil des Gehäuses als ein im letzteren drehbar und unverschiebbar gelagerter Ring ausgebildet. Die Lösung der Befestigung erfolgt daher durch das Verdrehen dieses Ringes, ohne Verdrehen des Laufes - und daher unter anderem auch ohne die Gefahr der Änderung der festgelegten Schußri:chtung.According to the invention is the one containing the nut thread for the barrel thread Part of the housing as a ring rotatably and immovably mounted in the latter educated. The fastening is therefore released by twisting it Ring, without twisting the barrel - and therefore, among other things, without the danger the change of the fixed shooting direction.

Die Einrichtung gemäß der Erfindung ist auf der Zeichnung dargestellt. Es zeigt: Abb. i einen axialen. Längsschnitt, Abb. 2 einen O_uerschnitt.The device according to the invention is shown in the drawing. It shows: Fig. I an axial. Longitudinal section, Fig. 2 an O_u section.

Der Lauf D ist im Gehäuse B abnehmbar eingeschoben und mit Schraubengewinde versehen, welches aus mehreren Segmenten besteht. Diese sind durch gewindelose Zwischenräume voneinander getrennt, deren Teilungswinkel denjenigen der Gewindesegmente entsprechen. In dem zeichnerisch dargestellten Ausführungsbeispiele sind drei Gewindesegmente vorgesehen, die symmetrisch verteilt sind und deren Teilungswinkel je 6o° beträgt. In einem Ausschnitte des Gehäuses B ist ein Laufbefestigungsring A eingelegt, der mit Muttergewinde versehen ist, welches zum Eingriff mit dem Gewinde des Laufes D eingerichtet ist. Dieses Muttergewinde besteht gleichfalls aus Segmenten, deren Anzahl und Teilungswinkel denjenigen des Laufgewindes entsprechen, so daß der Ring A durch Verdrehen um den Teilungswinkel im einen oder anderen Drehsinne in oder außer Eingriff mit dem- Laufgewinde ,gebracht und dementsprechend der Lauf D entweder im Gehäuse B gegen Verschieben gesichert oder zum Auswechseln durch axiales Verschieben und Herausnehmen freigelegt wird. Der Ring A ist zwecks leichter Handhabung seitlich mit einem Halter A, versehen, der am freien Ende eine drehbare, unter der Einwirkung einer Feder stehende Einfallklinke C trägt und derart ausgestaltet ist, daß er sich beim Verdrehen in die Schließlage an den unteren Rand des Gehäuses B legt, wobei die Klinke C selbsttätig mit diesem Rande in Eingriff kommt und auf diese Weise den Ring A gegen unbeabsichtigtes Verdrehen sichert.The barrel D is detachably inserted in the housing B and provided with a screw thread, which consists of several segments. These are separated from one another by threadless spaces, the pitch angles of which correspond to those of the thread segments. In the exemplary embodiment shown in the drawing, three thread segments are provided which are symmetrically distributed and whose pitch angle is 60 ° each. In a cutout of the housing B, a barrel fastening ring A is inserted, which is provided with a nut thread, which is set up for engagement with the thread of the barrel D. This nut thread also consists of segments, the number and pitch angle of which correspond to those of the barrel thread, so that the ring A is brought into or out of engagement with the barrel thread by turning the pitch angle in one or the other direction, and accordingly the barrel D is either in the housing B secured against displacement or exposed for replacement by axial displacement and removal. For easy handling, the ring A is laterally provided with a holder A, which at the free end has a rotatable catch catch C under the action of a spring and is designed in such a way that it moves against the lower edge of the housing when it is turned into the closed position B sets, the pawl C automatically engages with this edge and in this way secures the ring A against unintentional rotation.
