Definitions

  • This invention relates to a device for compensating recoil torques in tank turrets and refers more particularly to a device for compensating the turning of a turret caused by the recoil force of a cannon which is excentrically mounted in the rotary turret.
  • An object of the present invention is to eliminate this drawback.
  • FIGURE 1 is a diagrammatic top view of a turret provided with a cannon and a compensating device of the present invention.
  • FIGURE 2 is a top view showing a somewhat different embodiment.
  • FIGURE 3 is a diagrammatic side view of a detail of the construction shown in FIG. 2.
  • FIG. 1 shows a turret mounted upon a tank and carrying a weapon 12 which may be an automatic cannon.
  • the recoil force of the cannon is received by a first spring 14.
  • the cannon is not placed in the middle of the turret but to one side thereof, indicated by the line a. In this position of the cannon, the recoil force will result in a torque, causing the turret to turn clockwise; the torque is produced by the force P acting upon the spring 14 and the lever arm a of the cannon in relation to the center C of the turret.
  • this torque is compensated by producing a torque acting in the opposite direction.
  • the cannon 12 is connected through a pivot 16 with a telescoping rod 16 which is connected with a swingable arm 18.
  • the arm 18 actuates a driving member, such as a gear wheel, 20 by a diagrammatically indicated coupling 19.
  • the coupling 19 is the usual coupling of the type well known in the art.
  • the gear wheel 20 is rotatably mounted in the turret and meshes with a fixed member such as gear crown 22 which is firmly connected to a fixed part of the tank (not shown).
  • a second spring 24 which in the example shown FIG.
  • the gear wheel 20 Since the gear wheel 20 is always disconnected when the cannon returns to its position of rest, the efiect of the spring 24 is switched off or brought to zero a certain number of times per second, depending upon the speed of firing.
  • the tension of the spring 24 is directly dependent upon the turning of the turret between two shots corresponding to the speed of rotation.
  • the lastmentioned spring is replaced by a torsion spring 30 having the shape of a thin rod which is enclosed by a tube 32.
  • the lower end of the tube 32 is closed by a plate 34 in which the torsion spring rod 30 is rigidly mounted.
  • the torsion spring rod 30 can turn elastically clockwise or counterclockwise, as seen in the direction of the arrow 38.
  • Both ends of the tube 32 are mounted in the turret 10, as indicated diagrammatically by the numeral 38 in FIG. 2, so that the tube can follow the elastic turnings of the torsion rod.
  • the tube 32 serves as the member transmitting the forces acting upon the torsion spring 30 and the forces emanating from the torsion spring 30.
  • the upper end 36 of the torsion spring 30 is provided with a swinging arm 40 which is connected with the weapon 44 by means of an arm 42 (FIG. 2).
  • a second arm 46 is attached to the tube 32 at a certain distance from the arm 42.
  • the arm 46 is coupled with a swinging arm 50 by means of a link 48 in a manner similar to the arrangement of the swinging arm 18 in the construction shown in FIG.
  • the swinging arm 50 is connected with a coupling 52 which actuates a gear Wheel 54 adapted to mesh with a gear crown 22 corresponding to the gear crown 22 of FIG. 1.
  • a coupling 52 which actuates a gear Wheel 54 adapted to mesh with a gear crown 22 corresponding to the gear crown 22 of FIG. 1.
  • gear wheel 20 and the gear crown can be replaced by a friction wheel having a frictional surface cooperating with the turret carrier.
  • a torque compensating device for a turret rotatably mounted upon a support and carrying an excentrically mounted cannon said device comprising a swingable arm, a member resiliently coupling said arm with said cannon, a coupling connected with said arm, a driving member rotated by said coupling, and a fixed member attached to said support and adapted to engage said driving member to stop the rotation thereof.
