Definitions

  • the invention relates to an elevation bearing for a large-caliber barrel weapon arranged in a tank turret with the features from the preamble of patent claim 1.
  • European laid-open specification No. 0 141 900 describes a conventional elevation bearing for armored vehicles with a rotatable armored turret, which is capable of keeping the large-caliber barrel weapon aligned with the target while the vehicle is traveling in stabilized straightening operation.
  • the weapon is held in its center of gravity with a shield pin bearing and is moved by a linear drive which acts on a pivot point and which can be designed as a hydraulic cylinder or ball screw spindle.
  • a disadvantage of this known design of an elevation drive is that in order to drive the forces to keep in a reasonable size, the barrel weapon must be hung about its center of gravity over shield pins. As tube weapons get bigger and longer, the tube end protrudes extremely far into the battle area of the tank turret. Attempts have been made to compensate for this by increasing the turning diameter and the height of the armored turret or by arranging compensators on the inner part of the barrel weapon. However, both measures have the disadvantage that the total weight of the armored vehicle is increased.
  • the purpose of the invention is to find an elevation bearing for a large-caliber barrel weapon, which makes it possible to store the barrel weapon outside the center of gravity without the eccentric barrel bearing having a significant influence on the drive power of the elevation drive.
  • the extreme forces due to pitching movements of an armored vehicle in non-stabilized driving operation in the field should not have to be taken over by the drive units.
  • this known elevation bearing is not suitable for use on armored vehicles with a rotatable turret in stabilized operation, since this known design is arranged directly in the armor. With stabilized operation, the large armor masses would have to be constantly moved, which in turn would make the required drive power unacceptably high.
  • Another disadvantage of the known arrangement consists in the fact that many overlaps of the armor would have to be provided in order to provide the necessary bullet security, which leads to high weight.
  • the invention has for its object to provide an elevation bearing with the features from the preamble of claim 1 so that it is suitable for stabilized operation on armored vehicles with a rotatable turret by significantly reducing the masses to be accelerated in stabilized operation.
  • the invention is based on the basic idea of designing the inclined ring bearing as a single structural unit and thus separate from the armor, which leads to a considerable reduction in the masses to be accelerated. It is also achieved that the usual elevation armor can be used on the tank tower. Due to the torsion-proof arrangement of the connecting flanges on the barrel weapon and on the turret and the drive device, the inclined ring bearing is sufficiently light and stable to be used as an elevation bearing for large-caliber barrel weapons for stabilized operation on armored vehicles with a rotating armored turret. The opposite drive of the two bearing rings from a common drive device creates a particularly space-saving and compact structure of the entire unit. This not only creates space in the combat area, but also saves weight.
  • the required radian measure at the inner end of the barrel weapon is significantly smaller and the required paths of the loading device become smaller. Furthermore, it is advantageous that the repercussions from the mass accelerations of the weapon when driving on the drive elements are significantly less than in the case of a shield journal bearing previously used.
  • a shield journal bearing previously used.
  • Another particular advantage of the elevation bearing according to the invention is that no end position damping of the drive and no end stops need to be provided, since the relationship between the elevation movement and drive runs according to a sine function.
  • a backlash-free drive is achieved, which brings increased stabilization and target accuracy compared to the shield journal bearing previously used in these cases.
  • the elevation bearing arrangement according to the invention also opens up the possibility of achieving a considerable reduction in the mechanical moving parts and thus an increased level of accuracy by directly engaging a pinion in the toothing of the bearing rings.
  • a large-caliber barrel weapon 3 is arranged in the tank tower, the end piece 3a of which protrudes into the combat area, while the front end of the barrel is led to the outside through a slot 1 a, which is not shown in the illustration by a conventional armor.
  • the barrel weapon 3 is suspended in the tank turret 1 by means of an oblique ring bearing comprising the barrel 3 described below.
  • the inclined ring bearing has a first connecting flange 4 connected to the cradle tube 3b comprising the tube 3 via screw connections 4a, on which a first bearing ring 6 is rotatably supported at one end about the tube axis RA via a ball or roller bearing 5.
  • the first bearing ring 6 is rotatably supported about a first axis of rotation D1 via a further ball or roller bearing 8 in a connecting ring 7, in which a second bearing ring opposite the first bearing ring 6 via a ball or roller bearing 9 about the axis of rotation D1 is rotatably mounted.
  • the second bearing ring 10 is rotatably mounted about a second axis of rotation D2 via ball or roller bearings 11 in a connecting flange 12.
  • the connecting flange 12 is connected to the bulkhead 1b in the turret 1 via screw connections 12a.
  • the connecting flange 4 carrying the tube 3 is connected in a rotationally fixed manner to the armored turret 1 in that the rear section 3c of the cradle tube 3b is designed as a square, which is guided in a slot 1c in the bulkhead wall 1b.
  • the connecting ring 7 is also rotatably but pivotably arranged with respect to the turret 1 by having a guide element 16 which is immersed in a holder 17 arranged on the turret 1 and provided with a groove running in the longitudinal direction.
  • the output shaft 13a drives a pinion 14, which is pressed under the action of a spring 15 into the space between the two bearing rings 6 and 10 such that it engages in gears 6a and 10a without play, which are arranged at the two opposite ends of the two bearing rings 6 and 10.
  • the three axes of rotation of the inclined ring bearing namely the tube axis RA, the first axis of rotation D1 and the second axis of rotation D2 each form acute angles ⁇ and ⁇ with one another.
  • the axes of rotation D1 and D2 intersect at a point P lying on the tube axis RA.
  • the angles between the first axis of rotation and the tube axis and between the second axis of rotation and the first axis of rotation become the same size for the desired purpose chosen. Under these conditions it is possible to achieve a swiveling movement of the non-rotatably arranged barrel weapon 3 in a vertical plane by rotating the two bearing rings in opposite directions by the same angular amounts.
  • the two bearing rings 6 and 10 are driven in the opposite direction of rotation by the same angular amounts by the pinion 14 arranged in the radial bearing plane E of the connecting ring 7 between the bearing rings 6 and 10.
  • the toothings 6a, 10a of the bearing rings 6, 10 are designed with the same number of teeth .
  • a spring-free drive is ensured by the spring 15.
  • the drive rings 6 and 10 can also be designed in a different way than according to the embodiment of FIGS. 1 and 2.
  • they can be the counter-rotating rotors of a directly driving ring motor arranged between them, which can be designed as a double electric torque ring motor.
