Definitions

  • the device In order to prevent the turret from traversing when the gun is fired or is being restored after recoil, the device is provided with a friction shoe which is engageable with a friction member fixed on the foundation.
  • a lever arrangement is provided, which, during recoil and counterrecoil, presses the friction shoe against the friction member and prevents the turning of the turret.
  • the arrangement includes a link structure which has bosses engageable with the friction shoe on turning in either direction and springs for positioning the friction shoe and the lever.
  • the present invention relates to a pivotable turret with a firing weapon arranged eccentrically and a means for preventing turret traversing caused by torque deriving from the recoil or counter-recoil force of said weapon.
  • a known device for compensating turret traversing caused by the recoil force of a weapon arranged eccentrically in a pivotable turret is characterised in that the weapon is connected by means of a spring link to a swinging bracket arranged through a transfer coupling member to turn a driving wheel, for example a toothed gear which is in engagement with a member to be driven, for example a toothed rim secured onto an object carrying the turret, for example a tank.
  • the invention is based on present the use of a regular braking means which secures the turret to the foundation and in which the braking force is obtained directly from the recoil and counter recoil force.
  • the braking means in itself is already known, but is influenced by an operating device which is activated prior to firing so that continued lateral directioning of the turret during automatic firing is not possible.
  • the weapon turret according to the invention includes a lever arrangement connected to the gun and actuated during recoil and counter-recoil a friction shoe which engages a friction surface secured to the foundation. The lever and the shoe are centered by springs or the like.
  • FIG. 1 shows one embodiment of a weapon turret with weapon and braking means arranged therein
  • FIGS. 2 and 3 show another embodiment.
  • a weapon turret located on a tank, for example.
  • a weapon l1 for example a quick-firing weapon is placed in the turret 10. Because of the lack of space the weapon is not placed in the centre of the turret, but is somewhat displaced laterally, more specifically at a distance a from the centre C of the turret. If the weapon 11 were rigidly secured in this position in the turret 10, it would be caused to pivot clockwise by a recoil force and counter-clockwise by a counter-recoil force because of the torque.
  • the object of the invention is to eliminate this effect of the recoil and counter-recoil force and to counteract the torque by mounting the weapon 11 in such a way that said forces are compensated.
  • the weapon is therefore connected either directly or through a double-acting spring unit 12 to a connecting arm 13 arranged pivotably on a schematically shown compensator, for example a compensating lever 14, and is centred in lever 14 by means of two centering springs 15, 16.
  • the compensating lever 14 is in turn suitably pivotable in the centre C of the turret and, in relation to the turret 10, is centred by two restoring springs 17, 18 located between an easily displaced activating member, for example a block 19, arranged on the compensating lever 14, and two bosses 20, 21 on the turret 10.
  • the weapon 11 In its neutral position, the weapon 11 is thus centred with the help of the doubleacting spring unit 12, centering springs 15, 16 and restoring springs 17, 18.
  • the connecting arm 13 Upon a recoil or counter recoil from the weapon 11, the purpose of the connecting arm 13 is to influence the block 19 by way of a first or second boss 13 a, 13 b, so that the block is clamped against a receiving member, for example a friction surface 22 placed on the object carrying the turret 10.
  • the device has a double-acting function and locks the turret 10 against the friction surface 22 for either recoil or counter recoil forces from the weapon 1 1.
  • Another possibility is for two braking blocks to be influenced by the recoil force and the counter recoil force, respectively.
  • the connecting arm 13 and compensating lever 14 are in neutral position, the position shown in the drawing, so that the turret can be turned without being affected by forces from the weapon 1 1.
  • the recoil force from the weapon acts by way of the spring unit 12 on the connecting arm 13.
  • the spring unit 12 is double-acting to dampen the initial force caused by recoil or counter recoil of the weapon.
  • the pressure produced by the spring unit 12 influences the connecting arm 13 and endeavours to turn this counterclockwise. However, in the first instant it is met by counter force from the centering springs 15, 16.
  • the direct torque caused by the recoil and exerted on the turret is of the following magnitude
  • the choice of the pivot point for the compensating lever 14 is dependent on the forces existing in the various springs 12, 15, 16, 17, 18 before and after activation of the connecting block 19.
  • the weapon l1 resumes its normal position at the same time as the centering springs 15, 16 return the connecting arm 13 to its neutral position.
  • the connecting block 19 is then re leased from the friction surface 22 and "the turret can be turned to a new firing position as desired.
  • the restoring springs 17, 18 have been added.
  • the connecting block 19 When the connecting block 19 is pressed against the friction surface 22 upon the occurrence of recoil or counter recoil and lateral directioning is performed, one of the two restoring springs 17, 18 is compressed. Which of the two springs is compressed depends on in the direction in which the weapon 11 and thus also the turret 10 is aimed.
  • the lateral directioning and compression of one of the restoring springs 17 or 18 thus caused results in the block 19, and with it the compensating arm 14 and connecting arm 13, assuming a position slightly displaced in relation to the turret 10.
  • the connecting block 19, compensating lever 14 and thus also the connecting arm 13 and weapon 11 return to their normal positions due to the action of the restoring springs l7, 18.
  • a shaft 28 for a toothed wheel 26 which is in engagement with the toothed rim 25 and can pivot freely on the shaft 28.
  • the weapon 11 is connected by the links 30, 31 to the link arm 29 on the shaft 28.
  • the link arm 31 is suitably in the form of a resilient shock absorber correspondingly to the spring 12in FIG. 1.
  • the link arm 29 can rotate on the shaft 28 and acts as an operating arm for a friction coupling or the like between the shaft 28 and the toothed wheel 26. In this way the recoil and counter recoil force from the weapon will be transmitted to the link arm 29 and the toothed wheel 26 will be locked rigidly on the shaft 28.
  • This causes the turret to be blocked with respect to the toothed rim 25 so that turret traversing due to recoil or counter recoil is prevented.
  • connection between toothed wheel 26, shaft 28 and links 29 may be as shown in FIG. 3, for example. This is clearly a form of free-wheel coupling by means of a combination of axial and pivoting forces.
  • the shaft 28 is journalled by means of ball-bearings in brackets 27, 27' in the turret 10.
  • a flange 32 In the middle of the shaft is a flange 32, below which is a flat disc 33. This is provided with pins 35 which can move in oblong slots 34 in the turret itself.
  • the disc 33 is thus prevented from turning with respect to the turret but it can move vertically on the shaft 28.
  • a plate spring 36 With the help of a plate spring 36 the disc 33 is pressed up against the flange 32 and the balls 37 rest in recesses therebetween in the disc and flange at the bottom of peripheral slots 38, 39, respectively in these.
  • the shaft is thus prevented from turning in relation to the turret with a force obtained from the spring force in 36 and the profile of the recesses for the balls 37.
  • the plate spring 36 thus has a function corresponding to the springs 17, 18 in FIG. 1.
  • the toothed wheel 26 is pivotably journalled on the shaft 28 between the flange 32 and an axially movable disc 40.
  • a pin or bolt 41 passing through the disc 40 and an oblong aperture 42 in the shaft 28 the disc is prevented from rotating on the shaft but can move axially on it.
  • flange 32 and disc 40 are friction surfaces and if the disc 40 is pressed down sufficiently hard, the toothed wheel becomes clamped tightly on the shaft 28 so that the turret is blocked against the toothed rim 25.
  • spring 40 thus corresponds to the springs 14, according to FIG. 1.
  • FIGS. 1 3 A combination of FIGS. 1 3 is also possible, in which the coupling according to FIG. 3 is fitted on the righthand end of the lever 14 in FIG. 1 instead of the braking block 19.
  • the friction surface 22 is then replaced by the toothed rim 25 according to FIG. 2.
  • the shaft 28 can be permanently fitted on the end of the arm 14, the plate spring 36 and disc 33 being replaced by the springs 17, 18 on the brackets 20, 21.
  • the link arm 13 must also be altered so that the recoil and counter-recoil force from the weapon can be transmitted to the link arm 29.
  • said link means between the weapon (11) and said second section (19) comprising a second set of springs (15,16) to neutralize said second section.
  • said first set of springs (l7, 18) being more pre-stressed than the second set (15,16).
  • Pivotable weapon turret according to claim 1 in which said first section comprises a friction surface (22) on the foundation, while the second section comprises a friction block (19) which is pressed against said friction surface by the recoil and counter-recoil force through said link means (13,14),
  • said first section comprising a toothed wheel (26) pivotably journalled on a shaft (28) in the turret (10) and in engagement with a toothed rim (25) on the foundation carrying the turret
  • the second section comprising at least one friction element (32, 40) which is forced against the toothed wheel by the recoil and counterrecoil force, and thus blocks the turret.
