Definitions
- the invention relates to a device for conveying taped ammunition to a automatic firearm by means of before the weapon on a star wheel shaft arranged Star wheels.
- the weapon usually also has an integrated belt feeder, the Star wheels are used to remove the belt from a magazine. They have to Exercise forces of variable size, accelerate quickly from standstill and allowed can not be driven at a rigid speed, with no synchronization to require the weapon.
- the invention has set itself the goal of such a device continues to improve, which is achieved by the fact that the spring also a closed Chain loop and the chain loop of at least two in a housing stored sprockets is formed, one of which with the star wheel shaft is drivingly connected, wherein the other end of a coil spring on a the chain loop attached pressure piece is supported.
- Coil springs provided (claim 2), which are at opposite ends Support shoulders in housing. This doubling means a parallel connection of two springs, whereby they are dimensioned smaller with the same power requirement can. It then causes no additional space and increases the Reliability.
- Another embodiment is that four sprockets are provided, two each on each side (claim 3). This allows instead of a given distance between the two strands of the chain loop big sprocket on each side two small ones are used. This further reduces the space required and allows a higher gear ratio in the drive of the starwheel shaft.
- Fig. 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 retractable strapped ammunition by a cartridge 3 with a part of the belt 4.
- Star wheels 5 are mounted on a drum 1 mounted in the frame 1.
- the drum 6 is via a break bolt coupling 7 with a star wheel shaft 8 drivingly connected, in the Star wheel drum 6 is mounted.
- a transmission gear 9 is arranged, which consists of a pair of gears consists and is driven by a connecting shaft 10, which in turn with a coaxial sprocket 11 is drivingly connected.
- the sprocket shaft 11 is between two Bearings 12 stored and carries in the middle between the bearings 12, a first sprocket thirteenth
- the first sprocket makes the connection to a spring accumulator 30 whose training can be seen better in Fig.2.
- the first sprocket 13 and a second, third and fourth Sprocket 14,15,16 are surrounded by a closed chain loop 17, the first Trum 18 and a second strand 19 forms.
- the chain is preferably a common link chain, as used to drive two-wheeled vehicles.
- Sprockets 13,14,15,16 and the chain loop 17 are 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, the connect both end blocks 21,22.
- the sprockets 14,15,16 are in one of the end blocks 21,22 rotatably mounted.
- the chain loop 17 is a first pressure piece 24 and a attached second pressure piece 25.
- the two end blocks 21,22 form at their the cladding tubes 23 facing sides shoulders 26,27.
- a first coil spring 28 is arranged between the shoulder 26 of the first end block 21st and the first pressure piece 24, a first coil spring 28 is arranged; between the second Shoulder 27 of the second end block 22 and the second pressure piece 25, a second coil spring 29.
- the two coil springs 28,29 are thus used in parallel and as compression springs.
- the coil springs 28,29 by an external device, not shown - which is a hand crank in the simplest case - tense.
- an external device not shown - which is a hand crank in the simplest case - tense.
- a coupling part 32 is provided, but it could also on the sprocket shaft 11 arranged or even be designed as a freewheel.
- the plungers 24,25 approximately in the middle of the ducts 23.
- a ratchet 33rd be provided, in which a frame-solid locking bolt 34 engages.
