Definitions

  • the invention relates to a belt feeder according to the preamble of patent claim 1.
  • Such a belt feeder and its drive is such. B. from DE-A-30 15 130 known.
  • Such belt feeders are operated in a clock-controlled manner in accordance with the firing rhythm, in that a switching element connected to the feed shaft of the belt feeder, in particular in the form of a star wheel, engages in the belt members in order to bring the cartridges held by them in succession into the removal position.
  • the feed shaft in turn can be connected to a drive source by means of a separable coupling.
  • DE-C-10 43 154 also discloses a belt feeder with a star wheel for feeding belted ammunition into a machine gun, in which a double lever mounted on the star wheel shaft represents a flexible stop for the front cartridge which has already been de-belted and which is next in the extended position to get what she experiences at this stop a change in her direction of movement from the circumferential direction of the star wheel in a radial direction in a radial channel to the extended position.
  • the coupling of the star wheel shaft is to engage with a certain rotational play in the connecting means to the drive source. Damage to toothed coupling parts in particular due to the reduced coverage of opposing tooth flanks and higher surface pressures cannot be avoided by the lever-like cartridge stop.
  • the invention has for its object to provide a novel belt feeder, in which the risk of such damage is eliminated, whereby greater reliability and reliability, in particular a longer life of the weapon can be achieved.
  • the belt feeder consists of a feed housing 3 in which a feed shaft 40 is rotatably mounted.
  • the feed shaft 40 can be connected at least temporarily to a drive source, also not shown, via a coupling (not shown in FIG. 1).
  • this drive source is usually an electric motor.
  • the drive energy is drawn in a known manner either from the return energy, from the gas pressure or from the breech movement.
  • the feed shaft 40 is a switching element in the form of a star wheel 9, which engages with its teeth in the cartridges 5, 6, 7 of the belt and moves these in cycles in the feed direction, so that the respective leading cartridge comes into the removal position. From this removal position, the cartridge is fed to the barrel through the breech, not shown.
  • the direction of rotation of the star wheel 9 acting as a switching element is indicated by the arrow identified by reference number 12 '; the resulting running or advancing direction of the belt 5, 6, 7 is indicated by the arrow 12.
  • the belt feeder 100 transports the belt 5, 6, 7 in the direction of the arrow 12.
  • the belt 5, 6, 7 thus excited can be switched off after the positively controlled advance lock, the parts of which are not shown in the drawing, and after being pushed out in the extended position located leading cartridge due to its inertia, the star wheel 9 and thus the rotationally fixedly connected to this star wheel 9 feed shaft 40 further in the transport direction 12 '.
  • the tooth surfaces of the transport clutch 21 and the transport pinion 20 have the large-area overlap designated X in FIG. 3.
  • the means consist in detail of a lever 1 with two lever arms 10 ', 10 ", which is pivotably mounted about an axis of rotation 4 arranged in the weapon housing 3 such that the lever arm 10' of the lever 1 into the running plane of the belt 5, 6, 7th protrudes.
  • the second lever arm 10 ′′ of the lever 1 has a stop surface c, which rests on a counter surface c ′ in the feeder housing in the rest position of the lever 1 and thus fixes the rest position or end position of the lever 1.
  • a stop surface c which rests on a counter surface c ′ in the feeder housing in the rest position of the lever 1 and thus fixes the rest position or end position of the lever 1.
  • Between the lever arm 10 ′ of the lever 1 and the A spring 2 is additionally arranged in the feeder housing 3, the end pieces of which are mounted in bores provided in the lever arm 10 'or in the feeder housing 3.
  • the spring 1 is biased by this spring 2 in such a way that it always strives to assume its rest position, at which the stop surface c rests on the counter surface c '.
  • Reference numeral 8 shows a cartridge which just passes the lever arm 10 'of the lever 1 during a transport step and thereby lifts this lever 1 into its second extreme position which deviates from the rest position.
  • the braking process described above is achieved. that in the non-driven state of the belt 5. 6, 7 can not move undesirably in the direction of thrust 12, with the result. that the feed shaft 40 is not caused to rotate and ultimately the tooth flanks in the coupling area can remain in the optimal position shown in FIG. 3.
  • the lever 1 also makes it easier to load the belt feeder with a filled belt, since when the belt guide piece is inserted, it presses it against the side wall 10 of the weapon housing 3 and thus enables the belt guide piece to be inserted into the de-belting rails 50, which are in the belt feeder 100 are arranged. In the same way, a safe introduction of the belt end itself is finally made possible, whereby inhibitions in the operational sequence of the weapon are avoided.
