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 type mentioned at the beginning which, in the case of an ignition failure, prevents an abrupt transfer of the kinetic energy of the rotating masses of the closure drive to be braked to the locking means and, in addition to a reduction in the masses looking up via the control roller, a continuously on and off decelerating energy transfer enables.
  • This energy transfer should also take place without interference with every ignition delay in the blocking position.
  • the blocking position assumed should be able to be released automatically after a waiting time.
  • the invention enables the kinetic energy of the rotating masses of the lock drive and the lock control to be rotatably and elastically stopped without causing interference 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 locking position of the breech drive.
  • the torsion bar spring is arranged inside the control roller, the rotating masses of the locking drive being stopped resiliently on one side of the control roller and the torsion bar spring directly on the other side, while avoiding the look-up effect of the rotating masses Control means of the locking element of the closure control is engaged.
  • FIG. 1 shows a closure drive 6 for a closure 34 movable between two symmetrically arranged control rollers 1.
  • the closure 34 can be pushed back and forth in grooves 35 of the control rollers 1 in the longitudinal direction of the elongated tube core axis 37.
  • the control rollers 1 are coupled on one side to a gear 14 within a weapon housing 36.
  • One end 10 of a torsion bar spring 2, which is rotatably arranged on the central axis 17 within each control roller 1, is in each case connected to the transmission 14 in a form-fitting manner.
  • the other end 11 of the torsion bar spring 2 is provided with a stop washer 12 of a stop device described in more detail in FIGS. 2 and 3.
  • the closure 34 of the cannon tube 38 is in the locked position due to the bolts 39 not belonging to the invention.
  • 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), it having to 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 connected to the end 10 of the torsion bar spring 2 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 by the control disc 12 in the weapon housing 36.
  • the control roller 1 is fastened 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.
  • a toothed bevel gear designed as a transmission means 7 and the stop disk 12 are positively connected.
  • the stop disk 12 and the bevel gear are expediently formed as one part.
  • Both bevel gears have the same number of teeth, so that the control means 8 is driven at the same speed of the torsion bar spring 2.
  • 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.
  • a locking element 4 is seated 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 disc 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 spirally from the outer radius 22 into the stop stop 3.
  • the stop stop 3 runs from the curve 15 at right angles to the outer surface 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 Longitudinal direction of its body axis 47 in the weapon housing 36 slidably arranged.
  • the gas locking bolt 5 provides an annular channel 29 for blocking or opening an opening 23 through which propellant gas can reach the annular space 50 via a further channel 49 in order to act upon the annular surface 28 of the blocking element 4.
  • 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 for releasing and rotating the Stop stop 3 is held briefly by the locking slide 27 which can be displaced 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 take place via a hydraulic cylinder 53 or a magnet (not shown), 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
  • 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 disc 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 can assume the starting position on the jacket of the stop disc 12 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 locking drive 6 including the control roller 1 and the gear 14 are now braked by the torsion bar spring 2 so that they can rotate.
  • the kinetic energy of its 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 in the direction opposite 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 4 has been released.
  • a test run of the locking device can also be carried out in a simple manner by the release of the locking element 4 which can be taken in via the unlocking lever 31.
