Definitions

  • the invention relates to a device for a forward-looking sleeve ejection of an externally driven machine cannon with a breech which can be moved longitudinally displaceably by a continuously rotating control roller, from which means for feeding a cartridge and for pushing out an empty cartridge case are simultaneously moved forward, for the feed and Ejecting process in the circumferential direction one behind the other pockets of an intermittently rotating rotor are provided, and that the means for ejecting the empty cartridge case is a sleeve pusher mounted longitudinally displaceable with respect to the rotor.
  • ejection levers are provided as a means for ejecting the empty cartridge cases on both sides in the outer region of the rotor and are connected to the breech and extend into the two laterally adjacent pockets of the rotor, optionally depending on the feed direction eject the empty cartridges from the left or the right rotor pocket to the front.
  • the ejection process of the sleeve on the lever-acting loads are disadvantageously transferred in full by the lever arrangement directly to the closure, whereby the connection point of the lever on the closure is subjected to unfavorably superimposed torsional, bending and shear stresses.
  • such superimposed tensions can have a negative effect on the operational readiness of the closure in the case of the long levers which are additionally angled in the pocket area of the rotor.
  • the ejection lever and the closure are made in one piece, which means that a considerable manufacturing outlay is required for manufacture and additional stresses due to notch effects can occur at the connection points, which would accelerate the early removal of the complete closure.
  • the means required for pushing out the sleeve as a sleeve slide that is mounted longitudinally displaceably within the rotor, storage of the sleeve slide that is independent of the closure is also achieved at the same time, which advantageously absorbs the tilting loads that occur during the sleeve ejection process.
  • a positive-locking connection between the sleeve slide and the closure which is only effective in the axial direction, provides, in a further advantageous manner over the known rigid connection, for a substantial reduction in the loads acting on the closure during the ejection process.
  • the sleeve slide is mounted on a drive shaft of the rotor arranged inside the rotor.
  • the driver elements of the sleeve slide it is also advantageously possible to design the driver elements of the sleeve slide to be comparatively short for ejecting the sleeves.
  • Favorable leverage ratios are created, the resulting low bending bursts being securely received by a tubular bearing housing of the sleeve slide and being transmitted over a large area to the shaft.
  • a slide or ball bearing arranged within the bearing housing further advantageously ensures a low-friction longitudinal displacement on the shaft.
  • the driving element contains a driving surface with a circular segment cross section for pushing out the sleeve.
  • This circular segment-like surface enables the sleeve to be supported over a large area when being pushed out, as a result of which deformations of the driving surface due to low surface pressures are avoided.
  • the interlocking connection between the slide and the closure consists of a circular segment-like driving spring which engages in a groove of the closure adapted to the driving spring, as a result of which the forces required for longitudinal displacement of the sleeve slide can be transmitted from the closure over a large area and thus only as low pressure loads .
  • the respective position of the groove and the respective width of the driving spring is furthermore advantageously larger than the size of the gaps between the driving springs, as a result of which a constant engagement of at least one driving spring in the groove and thus its axial fixation always remains guaranteed.
  • longitudinal slots are arranged in the rotor between each pocket and an axially extending bore provided for receiving the slide bearing housing, which ensure a common intermittent rotary movement of the sleeve slide with the rotor without additional drive means.
  • guide rollers are arranged in front of and behind the receiving groove, preferably in the front and rear breech area, which are mounted on both sides of the breech in prismatic guides and are almost free of play by actuators for a longitudinal displacement can be set. This guarantees a precise forward and backward movement of the closure, with the arrangement of the rollers at the very front and at the far rear reducing further freedom lines of the closure to a minimum.
  • the roller arrangement enables a low-load introduction of force to the weapon housing by the sleeve slide.
  • a rear contour of an insertion lever which can be controlled to feed the cartridges is designed as the outer boundary wall of the pocket provided for the pushing-out operation of the sleeves, so that additional guide parts are unnecessary.
  • Each pocket serving the sleeve shaft and lying on top in every rotor position is outside the rotor, for a targeted ejection of the sleeves forward into the outside area Gun cover, assigned to an ejection chute.
  • the push-out path of an ejection chute is always opened by a slide between the rotor and the ejection chute for pushing out the sleeves; on the other hand, the slide simultaneously closes the rotor chute serving the cartridge feed in the direction of the ejection chute and enables trouble-free cartridge feed.
  • the device is furthermore advantageously characterized in that the sleeve slide can be produced essentially as a cast without cutting and requires only minimal mechanical processing.
  • the arrangement of the slide within the rotor means that space can be exploited without increasing weight.
  • Figure 1 illustrates the structure of an externally powered machine gun 1, in which via a breech 3, which is movable longitudinally displaceably by a continuously rotating control roller 2, not only serves to feed the cartridges 6 in a cargo space 46 (FIG. 2) of the weapon barrel 39, but according to the details in FIGS. 2 to 10 eject mechanisms shown, pushing empty cartridge cases 7 forward out of an ejection chute 35 arranged on the right or left side of the weapon barrel 39.
  • a drive and gear unit 40 arranged on the rear of the machine cannon comprises the drive for the control roller 2, a stepping gear for a rotor 9, a further continuously rotating gear for the controlled feeding of the cartridges 6 via a respective insertion lever 34 and a change gear for reversing the cartridge feed, whereby a cartridge supply to the right or left of the weapon barrel according to FIGS. 9 and 10 is possible and only a sleeve ejection window 41 on the side facing away from the respective feed side of the rotor is released by a slide 36 shown in FIG. 8 for the sleeve ejection.

  • the integration of the sleeve slide 5 within the rotor 9 enables its longitudinal displacement and the sliding out of the sleeve 7 in a pocket 8 of the rotor 9 facing away from the closure 3 by a driver 10 of the sleeve slide 5 which projects radially into the pockets.
