Abstract

Bei einem Gurtzuführer einer gasdruckbetätigten ?auto?matischen Rohrwaffe erfolgt die Patronenzufuhr in den Laderaum der Waffe abwechselnd von zwei Seiten über in jeden Gurt eingreifende Zuführwellensterne je einer Zuführwelle (5), die von einem Gaskolben über je eine Schaltratsche o. dgl. wechsel - und schrittweise um die Vorschubstrecke einer Patrone gedreht werden. Um ein Einklemmen der Patronen durch die Zuführwellensterne der Zuführwelle (5) infolge eines zu weiten Drehschrittes zu verhindern, wodurch deren Ableitung durch den Verschluss behindert und in nachteiliger Weise die Kadenz erniedrigt wird, ist auf jeder Zuführwelle (5) ein Klinkenrad (6) angeordnet, in dessen Klinkenlücken je eine Sperrklinke (4) eingreift, die unter der Kraft je einer Feder (7) in Richtung zur Achse der Zuführwelle (5) hin schwenkbar ist. Die Sperrklinke (4) wird mittels einer Steuerkurve (2) an einem koaxialen Antriebsritzel (1) und einem zwischen dieser Steuerkurve (2) und der Sperrklinke (4) eingesetzten Steuerstift (3) dann wenn die Zuführwelle von dem Gaskolben nicht bewegt wird, mit den Klinkenlücken des Klinkenrades (6) ausser Eingriff gebracht. Während der Drehung der Zuführwelle (5), also während des Gurttransports, fährt die Sperrklinke (4) jedoch in die Klinkenlücken des Klinkenrades (6) ein, ist am Ende der Drehung in diese eingerastet und begrenzt somit ruckartig den Gurttransport.In the case of a belt feeder of a gas-pressure-operated? Automatic? Barrel weapon, the cartridge is fed into the loading space of the weapon alternately from two sides via feed shaft stars engaging in each belt, each with a feed shaft (5), which changes from a gas piston via a switching ratchet or the like - and be gradually rotated around the feed distance of a cartridge. A ratchet wheel (6) is arranged on each feed shaft (5) in order to prevent the cartridges from being jammed by the feed shaft stars of the feed shaft (5) as a result of an excessively large turning step, as a result of which their derivation is hindered by the closure and the cadence is disadvantageously reduced , in the pawl gaps a pawl (4) engages which can be pivoted under the force of a spring (7) in the direction of the axis of the feed shaft (5). The pawl (4) is by means of a control cam (2) on a coaxial drive pinion (1) and a control pin (3) inserted between this control cam (2) and the pawl (4) when the feed shaft is not moved by the gas piston the pawl gaps of the ratchet wheel (6) disengaged. However, during the rotation of the feed shaft (5), i.e. during the belt transport, the pawl (4) moves into the pawl gaps of the ratchet wheel (6), is locked in at the end of the rotation and thus abruptly limits the belt transport.

Description

Die Erfindung betrifft einen Gurtzuführer einer automatischen Gasdrucklader-Rohrwaffe, insbesondere einer Maschinenkanone, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a belt feeder of an automatic gas-pressure gun barrel weapon, in particular a machine gun, with the features of the preamble of claim 1.

Ein solcher Gurtzuführer und sein Antrieb ist z.B. aus der DE-OS 28 09 505 als bekannt zu entnehmen. Bei diesem bekannten Gurtzuführer kann es vorkommen, daß die Zuführwellensterne der Zuführwelle nach Beendigung des Transports des Gurtzuführers die Patrone einklemmen und dadurch deren Ableitung durch den Verschluß behindern. Dadurch kann die Patronenhülse beim Ableiten beschädigt werden und es tritt eine höhere Belastung der Zuführwellensterne und,damit verbunden,gegebenenfalls ein Abfallen der Kadenz ein. Diese Nachteile treten besonders stark auf, wenn beim Schießen das Gurtende erreicht oder nahezu erreicht ist, weil dann auf den weniger Masse aufweisenden Gurt der gleiche Impuls des Antriebs ausgeübt wird.Such a belt feeder and its drive can be seen, for example, from DE-OS 28 09 505 as known. In this known belt feeder it can happen that the feed shaft stars of the feed shaft clamp the cartridge after the transport of the belt feeder has ended and thereby hinder their discharge through the closure. As a result, the cartridge case can be damaged when it is discharged, and there is a higher load on the feed shaft stars and, associated with this, the cadence may drop. These disadvantages occur particularly strongly when the belt end is reached or almost reached when shooting, because then the belt with less mass the same impulse of the drive is exerted.

Aufgabe der Erfindung ist es daher, die genannten Nachteile zu vermeiden. Die Zuführwellensterne sollen die Patronenhülse nach Beendigung des jeweiligen Transports nicht mehr beschädigen, es soll keine erhöhte Belastung der Zuführwellensterne eintreten und ein Kadenzabfall soll vermieden werden. Dabei soll durch die zur Verhinderung dieser Nachteile eingesetzten Mittel das Be- und Entladen der Waffe und auch der Aus- und Einbau d.er Zuführwellen nicht behindert werden. Weiterhin sollen die Mittel in Gurtzuführern beliebiger, unterschiedlicher Konstruktion einsetzbar sein.The object of the invention is therefore to avoid the disadvantages mentioned. The feed shaft stars should no longer damage the cartridge case after the end of the respective transport, there should be no increased stress on the feed shaft stars and a cadence drop should be avoided. The means used to prevent these disadvantages should not impede the loading and unloading of the weapon and the removal and installation of the feed shafts. Furthermore, the means should be usable in belt feeders of any different construction.

Die genannte Aufgabe wird bei dem eingangs genannten Gurtzuführer durch die im kennzeichnenden Teil des Anspruchs 1 genannten Merkmale gelöst. Die Unteransprüche nennen Weiterbildungen der Erfindung des Anspruchs 1..The stated object is achieved in the belt feeder mentioned at the outset by the features mentioned in the characterizing part of claim 1. The subclaims name developments of the invention of claim 1.

Durch die im Anspruch 1 genannten Merkmale ist für die Zuführwellensterne eine Vorlaufbremse geschaffen, die jeweils am Ende des Vorschubs des Gurtes durch das Einrasten der Sperrklinke die Drehung des jeweiligen Zuführwellensterns ruckartig begrenzt. Dadurch kann kein Einklemmen der Patronen mehr erfolgen. Dadurch, daß die Sperrklinke in der Nullstellung, also wenn die Zuführwelle nicht gedreht wird, ganz. aus dem Klinkenrad ausgefahren ist, wird das Be- und Ent- laden der Waffe nicht behindert. Durch die Anordnung des Antriebsritzels am vorderen Ende jeder Zuführwelle ist der einfache Ein- und Ausbau der Zuführwellen gewährleistet.Due to the features mentioned in claim 1, a feed brake is created for the feed shaft, which jerkily limits the rotation of the respective feed shaft at the end of the feed of the belt by engaging the pawl. This means that the cartridges can no longer be jammed. The fact that the pawl in the zero position, so when the feed shaft is not rotated, completely. when the ratchet wheel is extended, loading and unloading of the weapon is not hindered. The arrangement of the drive pinion at the front end of each feed shaft ensures easy installation and removal of the feed shafts.

Eine besonders günstige konstruktive Ausbildung ergibt sich dadurch, daß die Sperrklinken zweiarmige, einseitig feder- . belastete Hebel sind und daß sie auf gemeinsamer Welle zwischen den Zuführwellen gelagert sind. Kürzere Lagerwellen für die Sperrklinken ergeben sich, wenn jede Sperrklinke auf einer eigenen, zwischen den Zuführwellen nebeneinander liegenden Lagerwelle gelagert ist.A particularly favorable structural design results from the fact that the pawls are two-armed, spring-sided. are loaded levers and that they are mounted on a common shaft between the feed shafts. Shorter L age rwellen for the pawls result when each pawl is mounted on a separate, juxtaposed between the Zuführwellen bearing shaft.

Die Zeichnung zeigt eine Ausführungsform des neuen Gurtzuführers mit der Vorlaufbremse für die Zuführwellensterne und zwar in

  • Figur 1 im lotrechten Schnitt teilweise in Ansicht im Bereich des vorderen Endes der Zuführwellen, in
  • Figur 2 im zur Figur 1 rechtwinkligen, lotrechten Schnitt längs der Mittelachse einer Zuführwelle und in
  • Figur 3 im zur Figur 1 rechtwinkligen, lotrechten Schnitt längs der Mittelachse der Lagerwelle.
The drawing shows an embodiment of the new belt feeder with the feed brake for the feed shaft stars, namely in
  • 1 in vertical section partially in view in the region of the front end of the feed shafts, in
  • FIG. 2 in a perpendicular section perpendicular to FIG. 1 along the central axis of a feed shaft and in
  • 3 in a perpendicular section perpendicular to FIG. 1 along the central axis of the bearing shaft.

Figur 1 und 2 zeigen, umgeben von einem Gehäuse 12, rechts die Zuführwelle 5 mit Klinkenrad 6 und Antriebsritzel 1, die rechts herum antreibbar sind, und links das etwas weiter nach hinten liegende Klinkenrad 6, ebenfalls einteilig mit der Zuführwelle 5 und davor das Antriebsritzel 1, die links herum antreibbar sind. Jeder Steuerkurve 2 an dem Antriebsritzel 1 ist ein Steuerstift 3 und eine Sperrklinke 4 zugeordnet. Die Sperrklinken 4 sind auf der feststehenden Lagerwelle 8 drehbar gelagert. In ihren oberen Hebelarm greifen Druckfedern 7 ein, die am Gehäuse 12 abgestützt sind.Figures 1 and 2 show, surrounded by a housing 12, on the right the feed shaft 5 with ratchet wheel 6 and drive pinion 1, which can be driven to the right, and on the left the ratchet wheel 6 lying a little further back, likewise in one piece with the feed shaft 5 and in front of it the drive pinion 1, which can be driven to the left. Each control cam 2 on the drive pinion 1 is assigned a control pin 3 and a pawl 4. The pawls 4 are rotatably mounted on the fixed bearing shaft 8. Compression springs 7, which are supported on the housing 12, engage in their upper lever arm.

Figur 2 zeigt, daß der Steuerstift 3 in einer Bohrung 13 eines Gehäusedeckels 9 gehalten ist.Figure 2 shows that the control pin 3 is held in a bore 13 of a housing cover 9.

Figur 3 zeigt die Lagerung der Welle 8, die die Sperrklinken 4 hintereinander trägt, in dem Gehäusedeckel 9, der hinten durch eine Abschlußplatte 10 abgedeckt ist. Damit die Sperrklinken auf einer Lagerwelle 8 hintereinander angebracht sein können, sind die Klinkenräder in Achsrichtung versetzt an den Zuführwellen angebracht.Figure 3 shows the bearing of the shaft 8, which carries the pawls 4 one behind the other, in the housing cover 9, which is covered at the rear by an end plate 10. So that the pawls can be mounted on a bearing shaft 8 one behind the other, the ratchet wheels are offset in the axial direction on the feed shafts.

Die Wirkungsweise der neuen Bremseinrichtung ist aus den Zeichnungen ersichtlich. Diese zeigen die Nullstellung, bei der der Steuerstift 3 ganz aus dem Antriebsritzel 1 herausgedrückt ist und dadurch auch die Sperrklinke 4 ganz aus dem Klinkenrad 6 herausgedrückt hat. Bei Drehung je eines Klinkenrades 6 infolge der Drehung der Zuführwelle 5 und des Antriebsritzels 1 gleitet der Steuerstift 3 entlang der Steuerkurve 2 in das Antriebsritzel 1 hinein, so daß dann der eine Hebelarm der Sperrklinke durch den Druck der Feder 7 auf den anderen Hebelarm in den Zwischenraum zwischen den Klinken des Klinkenrades 6 eingleitet und dessen Drehbewegung und damit auch die Drehung der Zuführwelle und der Zuführwellensterne am Ende der Transportbewegung des Gurtes stoppt.The operation of the new braking device can be seen from the drawings. These show the zero position, in which the control pin 3 is completely pushed out of the drive pinion 1 and thereby also the pawl 4 completely has pressed out of the ratchet wheel 6. Upon rotation of each ratchet wheel 6 as a result of the rotation of the feed shaft 5 and the drive pinion 1, the control pin 3 slides along the control cam 2 into the drive pinion 1, so that one lever arm of the pawl by the pressure of the spring 7 on the other lever arm into the Gap between the pawls of the ratchet wheel 6 and stops its rotation and thus also the rotation of the feed shaft and the feed shaft star at the end of the transport movement of the belt.
