Definitions

  • the invention relates to a device for the rapid stopping of an externally driven machine gun according to the preamble of patent claim 1.
  • the object of the invention is to provide a device of the aforementioned type, wherein a Misfire an abrupt transfer of the braked kinetic energy of the rotating masses prevents the shutter actuator to the locking means and in addition to a reduction in the look-up extending over the control roller masses a continuously Toggle which ' / nnd decelerating energy transfer enables. This energy transfer should also take place without interference with every ignition delay in the blocking position. For further readiness to fire, the blocking position taken should itself after a waiting period can be actively canceled.
  • the invention enables the kinetic energy of the rotating masses of the breech drive and the breech control to be rotatably and elastically stopped without causing malfunctions in the event of an ignition failure or an extremely delayed ignition.
  • the machine gun is immediately ready for use again after a waiting period due to the separate possibility of lifting the locked position of the breech drive.
  • the torsion bar spring is arranged inside the control roller, the rotating masses of the closure drive being stopped resiliently on one side of the control roller and the torsion bar spring on the other side directly avoiding the lookup effect of the rotating masses Control means of the locking element of the closure control is engaged.
  • the control roller 1 is driven via a closure drive 6 connected upstream of the transmission 14, which as the motor 40 can be both a hydraulic motor and an electric motor.
  • the gear 14 is simultaneously in engagement with the control roller 1 and the torsion bar spring 2 in such a way that there is a transmission ratio i of the speed of the control roller 1 to the speed of the torsion bar spring 2 of at least one (i ⁇ 1).
  • the transmission ratio i is determined by the course of the groove 35 (FIG. 1), wherein it must be taken into account that within a firing cycle the breech 34 (FIG. 1) is moved once in the direction of the gun barrel 38 (FIG. 1) and unlocked must be moved back again.
  • Each revolution of the torsion bar spring 2 corresponds to a locking and unlocking cycle of the closure 34 (FIG. 1).
  • the gear 14 is at the end 10 of the rotation rod spring 2 connected via a tooth profile 13 arranged thereon.
  • the torsion bar spring 2 is arranged centrally on the central axis 17 within the control roller, the end 10 in the control roller 1 and the end 11 outside the control roller 1 being supported by the control disk 12 in the weapon housing 36.
  • the control roller 1 is fixed within the weapon housing 36 in the bearings 41. On the outer jacket, the profile of the groove 35 is visible on the control roller 1.
  • a control body 42 required for locking the closure 34 (FIG. 1) is positively connected to the control roller 1, but is not considered here in greater detail.
  • an eccentrically designed unlocking disk 25 is fastened, which is rotatably arranged in a recess 44 of the locking slide 27.
  • the locking slide 27 is in a position displaced against the restoring force of the spring 26, from which it can be moved back by the spring force when the unlocking disk 25 is rotated further.
  • the locking element 4 On a curve 15 of the stop disk 12, there is a locking element 4 mounted in the weapon housing 36.
  • the locking element 4 is displaceable in the longitudinal direction of its body axis 45 and has an annular surface 28 for pressurizing gas, a locking surface 46 and a lifting surface 30.
  • the function of the locking element 4 in connection with the stop disk 12 and the aforementioned surfaces will be described in more detail with reference to FIG. 3.
  • the stop disk 12 which is positively connected to the torsion bar spring 2 via a tooth profile 33, contains on the circumference the curve 15 which merges from the outer radius 22 into the stop stop 3 in a spiral.
  • the stop stop 3 runs from the curve 15 at right angles to the outer jacket of the stop disc 12.
  • the stroke 21 of the control curve 9 results from the difference between the radii 22 and 20.
  • a stroke area 18 of the control curve 9 which transitions from the radius 20 into the outer radius 22 there is a gas locking bolt (5) in contact with the control curve 9 against a restoring force of the spring 48 longitudinally displaceable in the body housing 47 in the weapon housing 36.
  • the gas locking bolt 5 provides an annular channel 29 for shutting off or opening an opening 23 through which propellant gas can pass through a further channel 49 into the annular space 50 to act upon the annular surface 28 of the blocking element 4 in the event of a broken shot.
  • the blocking element 4, with its surfaces 51, 52 abutting the stop stop 3, is in the blocking position of the stop disc 12.
  • the end of the blocking element 4 facing away from the stop disc provides a locking surface 46 on which the blocking element 4 is released and Further rotation of the stop stop 3 is briefly held by the locking slide 27 which is displaceable in the housing 36.
  • the locking element 4 can be released independently of the propellant gas pressure against the restoring force of the spring 32 from the locking position of the stop stop 3 by a pivotable unlocking lever 31, the unlocking lever 31 being able to lift the locking element 4 on the lifting surface 30.
  • a separate unlocking can be done via a hydraulic cylinder 53 or a magnet, not shown, take place, the unlocking lever 31 pivotable about the bearing 54 being able to be reset by a spring 55 into the starting position of the locking position of the locking element 4.
  • the unlocking disk 25 has released the locking slide 27 for taking the holding position of the locking element 4.
  • the locking slide 27 holds the locking element 4 on its locking surface 46 in the release position until the stop stop 3 has passed the locking element 4 unhindered.
  • the unlocking disk 25 then unlocks the locking element 4 via the locking slide 27, so that under the restoring force of the spring 32, the locking element 4 the output position on the jacket of the stop disc 12 can take again. In the case of trouble-free operation, this sequence is repeated until it is interrupted by a firing device which is not part of the invention.
  • the shutter drive 6 including the control roller 1 and gear 14 are now decelerated in a rotatable manner.
  • the kinetic energy of their rotating masses is absorbed by the torsion bar spring 2 in an elastically braking manner due to the possibility of rotation of the torsion bar spring 2.
  • the locked position of the locking element 4 at the stop stop 3 can be released by actuating the unlocking lever 31, so that the closure 34 can move back and unlock to remove the non-fired ammunition.
  • no rotational movement of the stop disk 12 counter to the direction of rotation 16 is necessary, but the closure drive 6 can continue to run in the direction of rotation 16 of the stop disk 12 after the blocking position has been released by the blocking element 4. Due to the free on the unlocking lever 31 position of the locking element 4 can be carried out a trial run of the closure device in a simple manner.
