Definitions

  • the subject of the present invention is a shaft journal for the elevation in elevation of a plate on an armament mount.
  • the invention aims to achieve such a structure.
  • the invention also aims to provide a journaling structure which allows the self-alignment of the weapon support on the carriage as well as the catching up of variations in center distance of the carriage, due to the severe temperature variations that may undergo such a system in its operational use.
  • the invention therefore relates to a shaft journal for the journaling in elevation of a plate on a cocking carriage, said journal being carried by a site axis mounted tightly in the inner ring of a bearing disposed at the inside the bore of a housing secured to the carriage, characterized in that the outer ring of the bearing is slidably mounted inside the housing and in that an elastic means is interposed between the bearing and the bottom of the housing bore.
  • the journal is equipped with mechanical means capable of longitudinally displacing the site axis against the elastic means to release the axis of the journal partially in the bore of the housing during assembly of the deck on the lookout.
  • the mechanical means can be made inactive as soon as the plate is in place on the mount and secured to the pin, to allow axial sliding of the plate on the mount against the elastic means.
  • the mechanical means is constituted by a screw-nut system formed by the combination of a threaded end of the site axis passing through the bottom of the housing and of a nut carried by said end threaded, said nut being able to bear externally against the bottom of the housing.
  • the deployable mount incorporating the shaft journal according to the invention is arranged on the roof 1 of a vehicle (itself not shown).
  • the carriage has at its base a circular plate 2 rotating around a bearing axis ZZ on an extension 3 by means of a horizontal bearing 4.
  • the extension comprises a toothed circular 5 on which meshes a pinion 7 of a field encoder 6
  • the plate 2 comprises a rectangular armored hatch 8 opening by tilting backwards to serve as a passage for the servant of the lookout from inside the vehicle.
  • the tray 2 includes four boxes serving as bearings for a deployable chair, itself made up of two lyres, one front 9 and the other rear 10.
  • two front boxes 11 serving as a bearing for the front lyre
  • two rear boxes 12 serve as bearings for the rear lyre.
  • the front left 11 and rear 12 boxes are symmetrical between the right front and rear boxes with respect to a diametrical axis of the turntable.
  • Each front 9 and rear 10 lyre consists of a U-shaped bent tube, the base (respectively 9a, 10a) is provided with yokes (respectively 9b, 10b) equipped with articulation axes around which the lyres 9 rotate. and 10.
  • left 9c, 10c and right 9d, 10d are mounted, articulated on ball joints of the horizontal crosspieces (respectively left 13a and right 13b).
  • the assembly formed by the lyres 9 and 10 and the crosspieces 13a and 13b constitutes the articulated chair whose deployment is ensured by the form in two deformable parallelograms constituted by the plate 2, the left uprights 9c, 10c of the lyres and the crosspiece 13a (respectively the uprights 9d, 10d and the cross 13b).
  • the plate 14 On the chair thus formed is mounted the plate 14, support for the weapon (s) 15.
  • the plate 14 is rotatably mounted in elevation on a site axis YY materialized by pins 111 of the crosspieces 13a, 13b, said site axis being arranged in the vertical plane containing the axis of deposit 22.
  • the plate 14 supports two weapons 15 placed laterally on either side of the servant. It also supports a sighting device 17 in front of the servant.
  • FIG. 5 A general description of a mount incorporating the pin of site axis according to the invention having thus been made by way of example, reference will now be made to FIG. 5 for the description of the device according to the invention itself, ensuring the rotation in elevation of the plate 14.
  • two pins 111 carried by axes 112 are screwed by screws 113 to the plate 14.
  • the housing 114 of generally cylindrical tubular shape, is welded into the cross member 13a (or 13b).
  • the housing has a first bore 116 open towards the inside of the carriage, the bottom of the bore being closed by a wall 117 pierced with a central hole 18, said wall defining a second bore 119 open towards the outside of the lookout and which can be closed by a screwed flange 120.
  • the journalling axis 112 has a cylindrical bearing 112a terminated by a shoulder 112b and opposite the shoulder 112b, a threaded part 112C.
  • the pin 111 proper In abutment against the shoulder 112b is mounted the pin 111 proper, the latter comprising a cylindrical surface 111a against which abuts the internal ring of a roller bearing 121 mounted tight on the axis 12a.
  • the outer ring of the bearing 121 is slidably mounted.
  • a spacer 123 comes to bear against the lateral face of the outer ring of the bearing 121 opposite the bearing 11a of the journal relative to the bearing 121.
  • the threaded part 112c of the axis 112 passes through the wall 117 through the hole 118 thereof and supports a nut 125 housed in the housing 119.
  • the end of the thread 112c carries a circlip 126 which prevents the nut from being removed 125 out of thread 112c.
  • the pin 111 When mounting the plate 14 on the mount and in order to facilitate the introduction of the plate between the crosspieces 13a and 13b, the pin 111 must be released to maneuver the plate more easily.
  • the nut 125 is tightened on the thread 112c, the nut coming to bear on the outer face of the wall 117, thus driving the axis 112 and the pin 111, the outer ring to the right of the figure. of the bearing 121 sliding axially in the self-lubricating ring 122 of the housing 114, against the spring formed by the elastic washers 124. (In a variant, the latter could be replaced by a spiral spring).
  • the plate 14 is placed in position between the crosspieces and then the nut 125 is loosened in order to position the shoulder 112b of the axis 112 inside a bore 14a of the plate 14, thus giving the reference of rotation of the plate on the trunnion. It is then possible to rotate the pin 111 to coincide the holes in the plate and the threads of the pin which will make it possible to screw the plate 14 by the screws 113 on the pin.
  • the nut 125 can then be unscrewed until it no longer exerts any force on the wall 117, the nut remaining held by the retaining ring 126.
  • the flange 120 can then be closed.
  • the invention also relates to a weapon such as that described here carried by a plate capable of journalling on site on a mount and comprising two pins 111 of the type described, mounted in opposition on either side of the plate, such that '' they can be seen in Figures 3 and 4.
  • the cross members 13a, 13b of the chair support each a longitudinal cylinder 20 therefore the body is articulated at the rear of the cross member and comprises a spring which actuates a cable 21 wound on a pulley 129, itself secured in rotation in elevation of the plate by means of screws 130 and concentric with the pin 111 of said plate.
  • this device makes it possible to catch up on the clearances at the level of the site axis and to improve the precision of the system and the dynamic behavior when driving.
  • the elastic mounting of the trunnion axis in its housing has many advantages.
  • the fact of being able to disengage the journal axis in its housing facilitates the positioning of the plate on the carriage, which is important for example for the use of removable transportable carriage, or simply for maintenance operations on the weapon and / or the plate which supports it.
  • the elastic axial sliding mounting of the site pin journal allows the self-alignment of the weapon support on the mount and increases the flexibility of operation.
  • this type of mounting makes it possible to increase the tolerances for producing the supports (lyres and crosspieces) and makes it possible to make up for the variations in center distances due to the variations in temperatures when the mount is used in variable and / or severe climatic conditions.
