Description

Die Erfindung betrifft eine Ladevorrichtung für Maschinenkanone, insbesondere für eine fremd angetriebene Maschinenkanone, wie in der US 4 065 998 A beschrieben, die eine Grundlage für den Anspruch 1 bildet.The invention relates to a loading device for machine gun, in particular for a foreign-powered machine gun, as in US Pat. No. 4,065,998 described, which forms a basis for claim 1.

Die allgemeine Funktionsweise einer Maschinenkanone, hier einer gasdruckbetrieben sowie deren Aufbau kann der DE 37 31 035 A1 entnommen werden.The general functioning of a machine gun, here a gas-powered and their construction can the DE 37 31 035 A1 be removed.

Eine fremd angetriebene Maschinenkanone mit einem walzengesteuerten Geradezugverschluss beschreibt die DE 32 11 134 C1 . Dieser umschließt zwei gegensinnig drehbare Steuerwalzen mit je einer umfangsseitigen Steuernut zur axialen Hin- und Herbewegung eines Verschlusskörpers. Die Steuerwalzen befinden sich im Rückbereich des Rohres. Selbige Anordnung einer Steuerwalze ist auch in der DE 36 27 360 C1 dargestellt.A foreign-powered machine gun with a roller-controlled straight-pull closure describes the DE 32 11 134 C1 , This encloses two oppositely rotatable control rollers, each with a peripheral control groove for axial reciprocation of a closure body. The control rollers are located in the back of the pipe. Same arrangement of a control roller is also in the DE 36 27 360 C1 shown.

Eine Ladeeinrichtung für eine automatische Querverschluss- Rohrwaffe ist aus der DE 31 18 383 A1 bekannt, die zum geradlinigen und mit der Rohrseelenachse koaxialen Einführen einer Munitionseinheit dient. Die Ladeeinrichtung umfasst eine in einem Zubringergehäuse um eine Achse drehbar angeordnete Steuerwalze. Über die äußere Mantelfläche der Steuerwalze erstreckt sich eine Steuernut mit einem vorderen und einem rückseitigen Umlenkbereich. Das Zubringergehäuse befindet sich im Rückseitenbereich des Rohres. Das Zubringergehäuse weist eine linke und eine rechte Geradführungsnut für einen, mit dem Steuerorgan funktional zusammenwirkenden Träger auf.A loading device for an automatic cross-lock barrel weapon is from the DE 31 18 383 A1 known, which serves for the linear and coaxial with the tube axis axis introducing an ammunition unit. The charging device comprises a control roller rotatably arranged in a feeder housing about an axis. Over the outer circumferential surface of the control roller, a control groove extends with a front and a rear deflection region. The feeder housing is located in the back area of the pipe. The feeder housing has a left and a right Geradführungsnut for, with the control member functionally cooperating support.

Ein starr verriegelter Geradzugverschluss für eine fremd angetriebene Maschinenwaffe wird mit der DE 36 27 361 C1 publiziert. Für eine Raum sparende und prellfreie Verriegelung wird nur noch eine Steuerwalze vorgeschlagen, die von zwei um 180° versetzt zueinander und hintereinander angeordnete Gleichdicke umlaufen werden. Auch diese Steuerwalze befindet sich im hinteren Bereich der Waffe.A rigidly locked straight-pull fastener for a foreign-powered machine gun is with the DE 36 27 361 C1 published. For a space-saving and bounce-free locking only a control roller is proposed, which are rotated by two offset by 180 ° to each other and arranged one behind the other equal thickness. This control roller is located in the rear of the weapon.

Mit der DE 37 12 905 A1 wird eine Maschinenwaffe beschrieben, die u. a. eine Kurventrommel aufweist, die durch Fremdantrieb betätigt, zur Linearbewegung eines Geradezugverschlusses dient. Die Kurventrommel weist entsprechend eine über den Umfang endlos verlaufende Steuerkurve auf. Auf dem Umfang sind des Weiteren eine kurze radial wirkende Steuerkurve und eine längere axial wirkende Steuerkurve angeordnet.With the DE 37 12 905 A1 a machine gun is described which, inter alia, has a cam drum operated by external drive for the linear movement of a straight-pull fastener serves. The cam drum accordingly has a circumferentially endless control cam. Furthermore, a short radially acting control cam and a longer axially acting control cam are arranged on the circumference.

Bedingt durch Anordnung dieser Zuführungs- Nerschlusseinrichtungen im hinteren Bereich, d.h., hinter der Munitionszuführung und parallel und versetzt zur Rohrseelenachse sind derartige Waffen groß bauend. Dies trifft auch bei gasdruckbetriebenen Maschinenkanonen zu ( US 5,370,036 ).Due to the arrangement of these supply Nerschlusseinrichtungen in the rear, ie, behind the ammunition supply and parallel and offset from the tube soul axis such weapons are building large. This also applies to gas-powered machine guns ( US 5,370,036 ).

Die Erfindung greift die Aufgabe auf, eine Ladeeinrichtung aufzuzeigen, die eine kleiner bauende Waffe realisiert.The invention addresses the problem of pointing out a charging device that realizes a small-sized weapon.

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, eine, für die geradlinige Zuführung der Munition zu einem Waffenroh benötigte Steuerwalze in die Ebene der Rohrseelenachse einzubinden, vorzugsweise im Bereich eines Patronenlagers bzw. des Laderaumes. Dazu wird ein, wenigstens zwei Steuerkurven tragender Steuerkörper um das Waffengehäuse in diesem Bereich koaxial gelagert. Eine der beiden Steuerkurven befindet sich an der Mantelseite, die andere an der Stirnseite des Steuerkörpers. Durch diese beiden Steuerkurven wird über Steuerschieber oder Hebel der Verschluss geradlinig geführt und die Verschlussriegelung geöffnet bzw. geschlossen. Für die geradlinige Führung des Verschlusses mit Hilfe eines Verschlussschiebers erfolgt ein Umsetzen der Kurveninformation in eine geradlinige Bewegung. Der Steuerkörper selbst wird mit Hilfe eines Elektromotors angetrieben, wozu der Steuerkörper eine Rundumverzahnung aufweisen kann. In diese greift dazu ein Zahnrad, welches auf einer Welle sitzend mit einem am hinteren Ende der Waffe befindlichen Schrittgetriebe verbunden ist, das, bevorzugt direkt, vom Motor angetrieben wird. Dazu ist vorgesehen, dass der Motor mit dem Schrittgetriebe verbunden in dessen Nähe angeordnet ist. Diese Variante ermöglicht u. a. das Abkoppeln des Motors vom Steuerkörperantrieb. Alternativ kann der Motor im Bereich des Steuerkörpers abgebracht, diesen direkt antreiben, wie beispielsweise in der DE 37 12 905 A1 beschrieben.The invention is based on the idea of incorporating a control roller, which is required for the rectilinear supply of the ammunition to a gun barrel, into the plane of the tube bore axis, preferably in the region of a cartridge chamber or the loading space. For this purpose, a, at least two control curves bearing control body is mounted coaxially to the weapon housing in this area. One of the two cams is located on the shell side, the other on the front side of the control body. Through these two cams, the shutter is guided in a straight line via control slide or lever and the locking latch is opened or closed. For the rectilinear guidance of the closure with the aid of a closure slide, the curve information is converted into a rectilinear movement. The control body itself is driven by means of an electric motor, for which purpose the control body can have all-around toothing. In this attacks a gear, which is seated on a shaft connected to a located at the rear end of the weapon step gearbox, which is preferably driven directly from the engine. For this purpose, it is provided that the motor is arranged connected to the indexing gear in the vicinity thereof. This variant allows, among other things, the decoupling of the engine from the control body drive. Alternatively, the engine can be brought down in the area of the control body, drive it directly, such as in the DE 37 12 905 A1 described.

Wird ein, die Munition tragender Rotor verwendet, kann dieser durch das Schrittgetriebe verstellt werden, um die zu verschießende Munition vor den Verschluss zu legen. Andere Zuführungen der Munition sind jedoch auch möglich.If a rotor carrying the ammunition is used, it can be adjusted by the indexing gear in order to place the ammunition to be fired in front of the shutter. Other supplies of ammunition are also possible.

Neben einer reduzierten Baugröße und einer damit verbundenen Gewichtseinsparung sind weitere Vorteile die, dass die Kadenz frei wählbar ist und eine sichere Funktion gewährleistet wird. Je nach Wahl der Übersetzung zwischen einer Verzahnung des Verschlussschiebers und dem durch die mantelseitige Kurve geführten Zahnrad und einer feststehenden Zahnstange kann die Länge des Steuerkörpers gewählt bzw. variiert werden.In addition to a reduced size and associated weight savings are further advantages that the cadence is freely selectable and a safe function is guaranteed. Depending on the choice of the translation between a toothing of the shutter and the guided through the shell-side curve gear and a fixed rack, the length of the control body can be selected or varied.

Der nicht näher dargestellte Motor treibt den Steuerkörper 3 an. Die in die mantelseitige Steuerkurve 7 eingreifende Steuerrolle 14 des Schiebers 19 "Vorne" wird entlang der Steuerkurve 7 geführt, wodurch das mit der Steuerrolle 14 zusammenwirkende Zahnrad 16 die Verzahnung des Verschlussschiebers 19 entlang der feststehenden Zahnstange 17 geradlinig bewegt, bis der Schieber 19 "Hinten" erreicht hat. Die Steuerrolle 14 hat ihrerseits den Umkehrpunkt in der Steuerkurve 7 erreicht. Mit dem weiteren Verdrehen des Steuerkörpers 3 wird dadurch der Verschlussschieber 19 über die Verzahnung wieder nach vorne gebracht.The motor not shown drives the control body 3. The engaging in the shell-side cam 7 control roller 14 of the slider 19 "front" is guided along the cam 7, whereby the cooperating with the control roller 14 gear 16, the teeth of the shutter slide 19 along the fixed rack 17 moves straight until the slide 19 "rear " has reached. The control roller 14 has in turn reached the turning point in the control cam 7. As a result of the further rotation of the control body 3, the closure slide 19 is thereby brought forward again via the toothing.

Die am Steuerkörper 3 stirnseitige Steuerkurve 8 dient parallel zum Bewegen des Verschlusses 20 zur Steuerung der beiden Verschlussriegel 21, 22. Mit Verdrehung des Steuerkörpers 3 um seine Achse, wird auch die Steuerrolle 23 entlang der Steuerkurve 8 am linken Verschlussriegel 22 bewegt, wodurch der linke Verschlussriegel 22 aus- bzw. eingesteuert wird. Das Aussteuern erfolgt zur Freigabe des Verschlusses 20, das Einsteuern zur Sicherung. Mit Hilfe der beiden Winkelhebel 24, 25, wird dabei auch der andere Verschlussriegel 21 mit bewegt.With the rotation of the control body 3 about its axis, the control roller 23 along the control cam 8 on the left locking latch 22 is moved, whereby the left Locking bar 22 off or is controlled.
