Definitions

  • the invention relates to a rotary bearing of a saddle with a cradle receiving a gun barrel, primarily a launcher barrel, in which the saddle is rotatably mounted with the base plate to form a bearing or base plate and can be rotated by means of a gear which is made up of a drivable worm gear and a gear transmission engaging with the bearing or base plate and a clutch.
  • the rotary bearing described above belongs to the state of the art according to Article 54 (2) EPG.
  • DE-PS 308 479 describes a mine launcher with a side directional field of 360 ° .
  • the carriage is adjusted in the lateral direction using a handwheel and a pinion engaging in a ring gear.
  • the pinion can also be switched off so that the carriage can be turned directly by hand. No further details have been given.
  • a grenade launcher can be found in AT-PS 79 175, in which the double stand for the weapon barrel can be rotated around a pivot pin and can be fixed with a clamping screw. The grenade launcher can be adjusted to the side by turning it around the pivot pin. This requires loosening the clamping screw. In the uncoupled position, the uncoupled parts are not locked.
  • DE-OS 34 03 927 describes a device for manually rotating an armored turret by means of a hand crank via a gearbox with drive pinion and driven wheel, wherein a toothed arch attached to the armored vehicle engages with the drive wheel, in which a rotation of the armored turret, for example by the weapon tube getting caught on an obstacle, does not cause the hand crank to rotate, so that it cannot distribute any blows.
  • a self-locking locking device is provided in the crankshaft arranged between the hand crank and the drive pinion. This has a locking wedge which, depending on the direction of the torque, firmly connects the driving claw to the driven claw in one or the other position. A center position with free wheel is not provided.
  • a slip clutch is additionally arranged, which ensures between the drive-side part of the crankshaft and the drive pinion that a relative rotation of the drive pinion can take place in the locked position of the crankshaft, namely when e.g. the gun barrel, which strikes an obstacle when the armored vehicle is moving, should exert such a large torque on the drive pinion that the device would break without the slip clutch.
  • the object of the invention is to be able to quickly change and lock the lateral adjustment of the launcher tube in a structurally simple manner when the saddle is pivoted with a cradle carrying a launcher tube.
  • the invention is characterized in that on the shaft of the worm gear, a gear of the gear transmission can be rotated loosely and a coupling sleeve, which is displaceable in the axial direction and connected to the worm gear shaft in a rotationally fixed manner, engages with the gear via gear rings.
  • the coupling sleeve is adjustable by means of an adjusting device which has an angle lever which is rotatably mounted on a fixed axis, with one end cooperating with the coupling sleeve and with the other end engaging with a pull rod which is under spring action and by means of a hand lever, e.g. an eccentric lever is displaceable.
  • the actuating device for the clutch is designed to be simple and safe. There are only a few parts. Characterized in that a flat surface rests on a flat abutment surface when the lever is pivoted away, the risk is eliminated that coupling can inadvertently happen while the saddle is pivoted by hand with the cradle and the weapon barrel. To engage the clutch, a certain amount of force is required to transfer the hand lever into the vertical position to the contact surfaces, by overcoming the spring force. In the engaged position of the clutch, the fine adjustments for the lateral direction of the weapon located on the saddle are made by the gear by means of the handwheel.
  • the worm of the worm gear can have a shaft journal on which a manual operating device, e.g. a handwheel, which is connected to the shaft journal by means of a handlebar and intermediate universal joints, the hand-operated device being attached to the saddle.
  • a manual operating device e.g. a handwheel
  • the worm gear of the worm gear can also have a motor drive.
  • the gear wheel of the gear transmission meshes with an internal toothing of the base plate.
  • the transmission is advantageously arranged on a shoulder of the saddle.
  • Fig. 1 shows a grenade launcher 1 with a launch tube 2, which has a closed end cap 3 with bottom piece 4 at the lower end, which for articulated engagement with egg ner on the ground, for example the soil or the like, arranged plate is determined.
  • the launcher tube 2 is coupled to a recoil braking device 5 and is pivotably mounted in a cradle 7 by means of cross pins 6.
  • the cradle 7 is carried by a saddle 8 with a base plate 9 fixedly arranged thereon, the saddle frame 8, 9 being rotatably mounted to a fixed base plate 10 serving as a bearing.
  • the saddle frame 8, 9 is rotatably supported relative to the fixed bearing or base plate 10 by means of a gear 12.
  • a shaft 14 is rotatably mounted in the bearings 15 and with a worm wheel 16 non-rotatably connected.
  • the worm 17 has a free-standing shaft journal 19 which can be rotated by motor or by hand.
  • a gear 21 is loosely mounted, the ring gear 21 a of which engages with an annular inner ring gear 22 of the bearing or base plate 10.
  • the plate 10 is firmly connected to a stationary frame 23 by means of the screws 24, the stationary frame 23 being, for example, the substructure of a vehicle construction.
  • the coupling 26 has a coupling sleeve 27 which is mounted so as to be displaceable in the axial direction and is connected in a rotationally fixed manner to the shaft part 14a, as can be seen from the section in FIG. 5.
  • the coupling sleeve has an annular flange 27a with an internal toothing 28 which engages with an external toothing 29 of the toothed ring 21.
  • an angle lever 31 is pivotally mounted on a fixed axis 32.
  • the longer arm 31a of the angle lever 31 engages by means of rollers 33 in a groove 34 of the coupling sleeve 27.
  • the other leg 31b of the angle lever 31 is fork-shaped.
  • a pull rod 35 In the fork there is a pull rod 35, the inner end of which rests against the fork 31b of the angle lever 31 by means of a disk 36, advantageously with a spherical design.
  • the pull rod 35 is under the action of a spring 37 which acts against the other side of the fork 31 and is mounted in the stationary sleeve 38.
  • a handle 39 is arranged, which is designed as an eccentric lever.
  • the handle 39 is rotatably mounted about the eccentrically arranged pin 40, the rounded part 39a of the hand lever 39 being supported on the abutment plate 41.
  • the eccentricity of the bearing pin 40 pulls the pull rod 35 outwards against the action of the spring 37.
  • the bell crank 31 causes the bell crank 31 to rotate clockwise.
  • the coupling sleeve 27 is displaced upwards in the axial direction and the toothings 28 and 29 come out of engagement.
  • the saddle 8 with the base plate 9 is no longer connected to the gear 21.
  • the saddle 8 with the launcher tube can be pivoted freely in one or the other direction of rotation, which can be carried out easily and quickly since there is no more gear engagement.
  • the worm 17 is actuated via the shaft journal 19, in the case of the thrower expediently by hand.
  • a handwheel 45 is rotatably mounted on the saddle 8.
  • a housing 46 is connected to the saddle, in which a stub shaft 47 is rotatably mounted. This stub shaft 47 is connected to the axis of the handwheel 45 by means of bevel gears (not shown).
  • a link 48 and universal joints 49 and 50 are interposed as a connecting link.
  • an attachable sleeve 51 is arranged on the shaft journal 19, which is part of the universal joint 49.
  • the saddle 8 with the base plate 9 can be rotated clockwise and against it quickly and with slight play.
  • the housing 13 for the transmission 12 is expediently designed as an extension of the saddle 8.
  • annular intermediate piece 61 is arranged in a stationary manner by means of the screws 24.
  • the two ring-shaped parts enclose between them a bearing structure 62, by means of which a rotating ring 63 is rotatably mounted.
  • This inner rotating ring 63 represents the bearing on which the saddle 8, 9, which carries the cradle and the tube, is screwed, by means of the screw bolts 64, which engage in a threaded bush 65 of the inner rotating ring 63.
  • the saddle 9 is firmly connected to the saddle part 9a with the inner rotating ring 63, so that the saddle 9, 9a together with the gear 12 and the clutch 26 can be rotated in one direction or the other within the base plate parts 10 and 61.
