Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • first pressure piece 24 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.
  • a first coil spring 28 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.
  • the pressure pieces 24, 25 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.
  • the two coil springs 28, 29 are thus used in parallel and as compression springs.
  • an external device not shown - which in the simplest case is a hand crank - cocked.
  • a coupling part 32 is provided, but it could also on the chain wheel shaft 11 arranged or even be designed as a freewheel.
  • spring loaded are (Fig.2), the pressure pieces 24.25 approximately in the middle of the cladding tubes 23.
  • a ratchet wheel 33 can be placed on the star wheel drum be provided, in which a frame-fixed locking bolt 34 engages.
