Description

Die Erfindung handelt von einer Vorrichtung zum Fördern gegurteter Muniton zu einer automatischen Feuerwaffe mittels vor der Waffe auf einer Sternradwelle angeordneter Sternräder. Die Waffe verfügt meist auch über einen integrierten Gurtzuführer, die Sternräder dienen dem Abziehen des Gurtes aus einem Magazin. Dazu müssen sie Kräfte variabler Größe ausüben, schnell aus dem Stillstand beschleunigen und dürfen nicht mit starrer Geschwindigkeit angetrieben werden, um keine Synchronisation mit der Waffe zu erfordern.The invention relates to a device for conveying belted ammunition to one automatic firearm by means of a starwheel arranged in front of the weapon Star wheels. The weapon usually also has an integrated belt feeder, the star wheels are used to pull the belt out of a magazine. To do this, they need more variable forces Exercise size, accelerate quickly from standstill and must not be rigid Speed driven so as not to require synchronization with the weapon.

Deshalb sind bei schwereren automatischen Feuerwaffen starke Fremdantriebe mit aufwendiger Steuerung üblich. Gemäß der DE 20 11 236 C2 ist dazu eine Drehmomentmessung und eine steuerbare Kupplung erforderlich. Abgesehen vom Platzbedarf ist in einem Gefechtsfahrzeug die Störungsanfälligkeit kritisch.Therefore, heavy external drives are more expensive with heavier automatic firearms Control common. According to DE 20 11 236 C2 there is a torque measurement and a controllable clutch required. Apart from the space requirement is in a combat vehicle the susceptibility to failure is critical.

Es ist daher Ziel der Erfindung, eine möglichst raumökonomische und störungsunempfindliche Fördervorrichtung vorzuschlagen. Erfindungsgemäß wird das dadurch erreicht, daß die Sternradwelle von einem Federspeicher angetrieben wird, der aus einer als Druckfeder eingesetzten Schraubenfeder und einer geschlossenen Kettenschlaufe besteht.It is therefore the aim of the invention to be as space-efficient as possible and insensitive to interference Propose conveyor. According to the invention this is achieved in that the Star wheel shaft is driven by a spring accumulator, which is used as a compression spring Coil spring and a closed chain loop.

Durch die hohe Energiedichte (auf den Raumbedarf bezogene gespeicherte Energie) einer Schraubenfeder und den geringen Raumbedarf einer Kette werden sehr kleine Einbaumaße erreicht, wegen der Kettenschlaufe ist der Abtrieb sehr einfach, da diese selbst die Kraftübertragung übernimmt. Die Schraubenfeder in Verbindung mit der einfachen Kraftübertragung erlaubt die erforderliche hohe Beschleunigung. Der Einsatz der Schraubenfeder als Druckfeder hat den Vorteil, daß die Feder auch bei Bruch noch Kraft ausüben kann. Eine Steuerung ist auch nicht erforderlich, da die Feder sich dem Kraftbedarf anpasst.Due to the high energy density (stored energy related to the space requirement) one Coil spring and the small space requirement of a chain become very small installation dimensions reached, because of the chain loop, the downforce is very easy, since this itself is the power transmission takes over. The coil spring in connection with the simple power transmission allows the required high acceleration. The use of the coil spring as a compression spring has the advantage that the spring can still exert force even if it breaks. One control is also not necessary because the spring adapts to the power requirement.

In einer vorteilhaften Ausbildung wird die Kettenschlaufe von mindestens zwei in einem Gehäuse gelagerten Kettenrädern gebildet, von denen eines mit der Sternradwelle antriebsverbunden ist und ein Ende einer Schraubenfeder stützt sich im Gehäuse und das andere Ende auf einem auf der Kette angebrachten Druckstück ab (Anspruch 2). Eines der für die Spannung und Umlenkung der Kettenschlaufe erforderlichen Kettenräder wird so gleich als Abtriebselement verwendet. Die Verbindung zwischen Schraubenfeder und Kette über das Druckstück ist besonders einfach und zudem leicht einstellbar.In an advantageous embodiment, the chain loop of at least two in one Housing sprockets formed, one of which is drive-connected to the star wheel shaft is and one end of a coil spring is supported in the housing and the other end on a pressure piece attached to the chain (claim 2). One of those for tension and deflection of the chain loop required sprockets is the same as an output element used. The connection between coil spring and chain via the Pressure piece is particularly simple and also easily adjustable.

In einer bevorzugten Weiterbildung sind im Gehäuse zwei parallel angeordnete Schraubenfedern vorgesehen (Anspruch 3), die sich an entgegengesetzten Enden an Schultern im Gehäuse abstützen. Diese Verdopplung bedeutet eine Parallelschaltung der beiden Federn, wodurch diese bei gleichem Kraftbedarf kleiner dimensioniert werden können. Sie verursacht dann keinen zusätzlichen Raumbedarf und erhöht die Ausfallsicherheit.In a preferred development, two coil springs are arranged in parallel in the housing provided (claim 3), located at opposite ends on shoulders in the housing support. This doubling means a parallel connection of the two springs, whereby these can be dimensioned smaller with the same power requirement. It caused then no additional space requirements and increased reliability.

Eine weitere Ausbildung besteht darin, daß 4 Kettenräder vorgesehen sind, je zwei auf jeder Seite (Anspruch 4). Dadurch können statt eines bei gegebenem Abstand zwischen den beiden Trumen der Kettenschlaufe großen Kettenrades auf jeder Seite zwei kleine verwendet werden. Das verringert den Raumbedarf weiter und ermöglicht eine höhere Übersetzung im Antrieb der Sternradwelle.Another training is that 4 sprockets are provided, two on each Side (claim 4). This allows instead of one at a given distance between the two Dream of the chain loop large chain wheel uses two small ones on each side become. This further reduces the space requirement and enables a higher translation in the Star wheel shaft drive.

Alternativ oder kumulativ kann zur Wahl einer optimalen Übersetzung auch das mit der Sternradwelle antriebsverbundene Kettenrad auf einer Kettenradwelle sitzen, die die Sternradwelle über eine Verbindungswelle und ein Übersetzungsgetriebe antreibt (Anspruch 5). Dank der Verbindungswelle ist das Übersetzungsgetriebe raumökonomisch auf der dem Federspeicher abgewandten Seite der Sternradwelle angeordnet.Alternatively or cumulatively, the one with the Starwheel shaft drive-connected sprocket sit on a sprocket shaft that the Star wheel shaft drives via a connecting shaft and a transmission gear (claim 5). Thanks to the connecting shaft, the transmission gear is economically on the same Side of the star wheel shaft facing away from the spring accumulator.

Schließlich ist es noch praktisch, wenn die Sternradwelle auf dem dem Übersetzungsgetriebe abgewandten Ende einen Kuppelteil für eine externe Aufziehvorrichtung aufweist (Anspruch 6), so ist sie gut zugänglich.Finally, it is still practical if the star wheel shaft on the transmission gear opposite end has a dome part for an external mounting device 6), it is easily accessible.

Im Folgenden wird die Erfindung anhand von Abbildungen eines Ausführungsbeispieles beschrieben und erläutert. Es stellen dar:

Am der Brechbolzenkupplung 7 gegenüberliegenden Ende der Sternradwelle 8 ist ein Übersetzungsgetriebe 9 angeordnet, das aus einem Zahnradpaar besteht und von einer Verbindungswelle 10 angetrieben wird, die ihrerseits mit einer koaxialen Kettenradwelle 11 antriebsverbunden ist. Die Kettenradwelle 11 ist zwischen zwei Lagern 12 gelagert und trägt in der Mitte zwischen den Lagern 12 ein erstes Kettenrad 13.In Fig. 1, 1 is a frame of the device according to the invention or a magazine wall referred to, depending on the installation and application of the device. The feed direction is with indicated by an arrow 2, the belted ammunition to be drawn in with a cartridge 3 part of the belt 4. Intervening in the spaces between the cartridges Star wheels 5 are attached to a drum 6 mounted in the frame 1. The drum 6 is Drive connected via a breaking pin coupling 7 with a star wheel shaft 8, which in the Star wheel drum 6 is mounted. At the opposite end of the breaking pin coupling 7 the star wheel shaft 8, a transmission gear 9 is arranged, which consists of a gear pair exists and is driven by a connecting shaft 10, which in turn with a coaxial sprocket shaft 11 is drive-connected. The sprocket shaft 11 is between two Bearings 12 mounted and carries a first sprocket 13 in the middle between the bearings 12.

Das erste Kettenrad stellt die Verbindung zu einem Federspeicher 30 her, dessen Ausbildung in Fig.2 besser zu erkennen ist. Das erste Kettenrad 13 sowie ein zweites, drittes und viertes Kettenrad 14,15,16 sind von einer geschlossenen Kettenschlaufe 17 umgeben, die ein erstes Trum 18 und ein zweites Trum 19 bildet. Die Kette ist vorzugsweise eine übliche Gliederkette, wie sie zum Antrieb von Zweiradfahrzeugen benutzt wird. Kettenräder 13,14,15,16 und die Kettenschlaufe 17 befinden sich in einem Gehäuse 20, das aus einem ersten Endblock 21, der am Rahmen 1 angeschraubt ist, einem zweiten Endblock 22 sowie Hüllrohren 23, die die beiden Endblöcke 21,22 verbinden. Auch die Kettenräder 14,15,16 sind in einem der Endblöcke 21,22 drehbar gelagert.The first sprocket establishes the connection to a spring accumulator 30, the design of which can be seen better in FIG. The first sprocket 13 and a second, third and fourth Sprocket 14, 15, 16 are surrounded by a closed chain loop 17, which is a first Run 18 and a second run 19 forms. The chain is preferably a conventional link chain, how it is used to drive two-wheeled vehicles. Sprockets 13, 14, 15, 16 and the chain loop 17 are located in a housing 20, which consists of a first end block 21, which is screwed to the frame 1, a second end block 22 and cladding tubes 23 which the Connect the two end blocks 21, 22. The sprockets 14, 15, 16 are also in one of the end blocks 21,22 rotatably mounted.

Auf den beiden Trumen 18,19 der Kettenschlaufe 17 ist ein erstes Druckstück 24 und ein zweites Druckstück 25 befestigt. Die beiden Endblöcke 21,22 bilden an ihren den Hüllrohren 23 zugekehrten Seiten Schultern 26,27. Zwischen der Schulter 26 des ersten Endblockes 21 und dem ersten Druckstück 24 ist eine erste Spiralfeder 28 angeordnet; zwischen der zweiten Schulter 27 des zweiten Endblockes 22 und dem zweiten Druckstück 25 eine zweite Spiralfeder 29. Entsprechend der entgegengesetzten Bewegungsrichtung der beiden Trume 18,19 sind die Druckstücke 24,25 im entspannten Zustand an entgegengesetzten Enden der Hüllrohre 23. On the two runs 18, 19 of the chain loop 17 there is a first pressure piece 24 and one second pressure piece 25 attached. The two end blocks 21, 22 form on their cladding tubes 23 facing sides shoulders 26,27. Between the shoulder 26 of the first end block 21 and the first pressure piece 24 is arranged a first coil spring 28; between the second Shoulder 27 of the second end block 22 and the second pressure piece 25 a second coil spring 29. Corresponding to the opposite direction of movement of the two dreams 18, 19 are the pressure pieces 24, 25 in the relaxed state at opposite ends of the cladding tubes 23.

Die beiden Spiralfedern 28,29 sind somit parallel und als Druckfedern eingesetzt. Zum Laden des Federspeichers werden die Spiralfedern 28,29 durch eine nicht dargestellte, externe Vorrichtung - die im einfachsten Fall eine Handkurbel ist - gespannt. Dazu ist beispielsweise an der Sternradwelle 8 ein Kuppelteil 32 vorgesehen, er könnte aber auch auf der Kettenradwelle 11 angeordnet oder gar als Freilauf ausgebildet sein. Bei geladenem Federspeicher befinden sich (Fig.2) die Druckstücke 24,25 ungefähr in der Mitte der Hüllrohre 23. Um den Speicher in gespannter Stellung zu blockieren, kann auf der Sternradtrommel ein Sperrrad 33 vorgesehen sein, in das ein rahmenfester Sperrriegel 34 eingreift.The two coil springs 28, 29 are thus used in parallel and as compression springs.
