Description

Die Erfindung betrifft eine Elevationslagerung für eine in einem Panzerturm angeordnete großkalibrige Rohrwaffe mit den Merkmalen aus dem Oberbegriff des Patentanspru­ches 1.The invention relates to an elevation mount for a large-caliber barrel weapon arranged in a tank tower with the features from the preamble of patent claim 1.

Zum Höhenrichten einer in einem Panzerturm angeordneten Rohrwaffe ist eine Elevationslagerung erforderlich, die es erlaubt, den vorgesehenen Höhenrichtwinkel der Waffe zuzulassen. In der europäischen Offenlegungsschrift Nr. 0 141 900 ist eine übliche Elevationslagerung für Pan­zerfahrzeuge mit drehbarem Panzerturm beschrieben, die in der Lage ist, im stabilisierten Richtbetrieb die großkalibrige Rohrwaffe während der Fahrt des Fahrzeuges auf das Ziel ausgerichtet zu halten. Dabei wird die Waffe in ihrem Schwerpunkt mit einer Schildzapfenlage­rung gehalten und durch einen an einem Schwenkpunkt angreifenden Linearantrieb, der als Hydraulikzylinder oder Kugelrollspindel ausgebildet sein kann, bewegt.In order to adjust the height of a barrel weapon arranged in an armored turret, an elevation bearing is required which allows the intended height adjustment angle of the weapon to be permitted. European laid-open specification No. 0 141 900 describes a customary elevation bearing for armored vehicles with a rotating 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.

Ein Nachteil dieser bekannten Ausbildung eines Eleva­tionsantriebes besteht darin, daß, um die Antriebs­ kräfte in vertretbarer Größe zu halten, die Rohrwaffe etwa in ihrem Schwerpunkt über Schildzapfen aufgehängt werden muß. Bei immer größer und länger werdenden Rohr­waffen ragt das Rohrende dann extrem weit in den Kampf­raum des Panzerturmes. Es ist versucht worden dieses auszugleichen, indem der Drehdurchmesser und die Höhe des Panzerturmes vergrößert wurden oder am inneren Teil der Rohrwaffe Ausgleicher angeordnet wurden. Beide Maß­nahmen besitzen jedoch den Nachteil, daß das Gesamtge­wicht des Panzerfahrzeuges erhöht wird.A disadvantage of this known design of an elevator drive is that in order to drive To keep forces in a reasonable size, the barrel weapon must be hung about its center of gravity over shield pins. With longer and longer barrel weapons, the end of the barrel protrudes extremely far into the battle chamber 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.

Zweck der Erfindung ist es eine Elevationslagerung für eine großkalibrige Rohrwaffe zu finden, die es ermög­licht, die Rohrwaffe außerhalb des Schwerpunktes zu lagern, ohne daß die exzentrische Rohrlagerung wesent­lichen Einfluß auf die Antriebsleistung des Elevations­antriebes hat. Insbesondere sollen die Extremkräfte durch Nickbewegungen eines Panzerfahrzeuges im nichtsta­bilisierten Fahrbetrieb im Gelände nicht von den An­triebseinheiten übernommen werden müssen.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 of the center of gravity without the eccentric barrel bearing having a significant influence on the drive power of the elevation drive. In particular, 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.

Eine Elevationslagerung mit den Merkmalen aus dem Ober­begriff des Patentanspruches 1 ist in der DE-AS Nr. 20 37 819 beschrieben.An elevation bearing with the features from the preamble of claim 1 is described in DE-AS No. 20 37 819.

Diese bekannte Elevationslagerung ist jedoch nicht für den Einsatz an Panzerfahrzeugen mit drehbarem Panzerturm im stabilisierten Betrieb geeignet, da diese bekannte Ausbildung direkt in der Panzerung angeordnet ist. Beim stabilisierten Betrieb müßten somit ständig die großen Panzerungsmassen mitbewegt werden, wodurch wiederum die erforderlichen Antriebsleistungen unvertretbar hoch würden. Ein weiterer Nachteil der bekannten Anordnung besteht darin, daß viele Überlappungen der Panzerung vorgesehen werden müßten, um die erforderliche Beschuß­sicherheit zu erbringen, was zu hohem Gewicht führt.However, this known elevation bearing is not suitable for use on armored vehicles with a rotating armored 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 security against fire, which leads to high weight.

Bei der bekannten Anordnung sind weiterhin entweder zwei voneinander unabhängige Antriebsvorrichtungen erforder­lich, wobei über eine Steuerungsvorrichtung der Gleich­lauf der Lagerringe erzeugt wird oder es ist eine An­triebsvorrichtung vorhanden, die in aufwendiger Weise über viele mechanische Bewegungsteile mit den beiden Lagerringen gekoppelt ist. So werden bei dieser bekann­ten Ausführungsform insgesamt drei Zahnkränze benötigt, die mit einem Antriebsritzel und einem Vorgelegezahnrad zusammenwirken. Hieraus ergeben sich drei Zahneingriffs­punkte mit entsprechenden Ungenauigkeiten der Ver­zahnung. Zu weiteren Ungenauigkeiten im Antrieb führt die elastisch nachgiebige Lagerung der Vorgelegewelle.In the known arrangement, either two mutually independent drive devices are also required, the synchronism of the bearing rings being generated via a control device, or a drive device is present which is coupled to the two bearing rings in a complex manner via many mechanical moving parts. In this known embodiment, a total of three sprockets are required, which interact with a drive pinion and a counter gear. This results in three tooth engagement points with corresponding inaccuracies in the toothing. The elastically flexible bearing of the countershaft leads to further inaccuracies in the drive.

Der Erfindung liegt die Aufgabe zugrunde, eine Eleva­tionslagerung mit den Merkmalen aus dem Oberbegriff des Patentanspruches 1 so auszubilden, daß sie für den stabilisierten Betrieb an Panzerfahrzeugen mit drehbarem Panzerturm geeignet ist, indem die im stabilisierten Betrieb zu beschleunigenden Massen erheblich reduziert werden.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.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Patentan­spruches 1.This object is achieved according to the invention with the features from the characterizing part of patent claim 1.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous developments of the invention are described in the subclaims.

Die Erfindung geht von dem Grundgedanken aus, die Schrägringlagerung als Einzelbaueinheit auszubilden und damit von der Panzerung zu trennen, was zu einer erheb­lichen Reduzierung der zu beschleunigenden Massen führt. Weiterhin wird damit erreicht, daß am Panzerturm die übliche Elevationspanzerung eingesetzt werden kann. Durch die verdrehfeste Anordnung der Anschlußflansche an der Rohrwaffe und am Turm und der Antriebsvorrichtung wird die Schrägringlagerung genügend leicht und stabil, um als Elevationslagerung für großkalibrige Rohrwaffen für den stabilisierten Betrieb an Panzerfahrzeugen mit drehbarem Panzerturm einsetzbar zu sein. Der gegensinni­ge Antrieb der beiden Lagerringe von einer gemeinsamen Antriebsvorrichtung aus schafft einen besonders platz­sparenden und kompakten Aufbau der Gesamteinheit. Da­durch wird nicht nur Platz im Kampfraum geschaffen, sondern auch Gewicht eingespart. Als besonderer Vorteil ergibt sich auch, daß das erforderliche Bogenmaß am inneren Ende der Rohrwaffe wesentlich geringer und damit die erforderlichen Wege der Ladevorrichtung kleiner werden. Weiterhin ist es vorteilhaft, daß die Rückwir­kungen aus den Massenbeschleunigungen der Waffe im Fahrbetrieb auf die Antriebselemente wesentlich geringer sind als bei einer bisher eingesetzten Schildzapfenlage­rung. Beim unstabilisierten Fahrbetrieb, bei dem sich die Waffe im unteren oder oberen Scheitelpunkt befindet, tritt keine Rückwirkung aus den Massenbeschleunigungs­kräften, hervorgerufen durch die Nickbewegung des Pan­zerfahrzeuges und damit der Waffe auf die Antriebsele­mente, auf, da die Schrägringlagerung in dieser Stellung die Kräfte direkt in den Turmflansch überträgt.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. It is also a particular advantage that 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. During unstabilized driving, when the weapon is at the lower or upper vertex, there is no reaction from the mass acceleration forces caused by the pitching movement of the armored vehicle and thus the weapon on the drive elements, since the inclined ring bearing in this position forces the forces directly into the Tower flange transmits.

Ein weiterer besonderer Vorteil der erfindungsgemäßen Elevationslagerung besteht darin, daß keine Endlagen­dämpfung des Antriebs sowie keine Endanschläge vorgese­hen zu werden brauchen, da die Beziehung zwischen Eleva­ tionsbewegung und Antrieb nach einer Sinusfunktion verläuft. Beim Einsatz vorgespannter Lager für die Schrägringlagerung und eines vorgespannten Antriebes wird ein spielfreier Antrieb erzielt, der gegenüber der bisher in diesen Fällen eingesetzten Schildzapfenlage­rung eine erhöhte Stabilisierungs- und Zielgenauigkeit bringt.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 Eleva tion movement and drive follows a sine function. When using preloaded bearings for the diagonal ring bearing and a preloaded drive, a backlash-free drive is achieved, which brings increased stabilization and target accuracy compared to the shield journal bearing previously used in these cases.

Die erfindungsgemäße Elevationslagerung eröffnet zudem die Möglichkeit, durch den direkten Eingriff eines Ritzels in die Verzahnung der Lagerringe eine erhebliche Reduzierung der mechanischen Bewegungsteile und damit eine erhöhte Richtgenauigkeit zu erzielen.The elevation bearing arrangement according to the invention also opens up the possibility of achieving a considerable reduction in the mechanical movement parts and thus an increased level of accuracy by directly engaging a pinion in the toothing of the bearing rings.

Im folgenden wird anhand der beigefügten Zeichnungen ein Ausführungsbeispiel für eine Elevationslagerung nach der Erfindung näher erläutert.An exemplary embodiment of an elevation bearing according to the invention is explained in more detail below with reference to the accompanying drawings.

In den Zeichnungen zeigen:

  • Fig. 1 in einem stark schematisierten Längsschnitt durch einen Panzerturm eine Elevationslage­rung für eine großkalibrige Rohrwaffe bei angehobener Stellung der Rohrwaffe;
  • Fig. 2 in einer Darstellung analog Fig. 1 die Eleva­tionslagerung bei abgesenkter Rohrwaffe;
The drawings show:
  • 1 in a highly schematic longitudinal section through an armored turret, an elevation bearing for a large-caliber tube weapon with the tube weapon in the raised position;
  • Fig. 2 in a representation analogous to Figure 1, the elevation with the barrel weapon lowered;

In Fig. 1 ist im Schnitt ein Panzerturm 1 dargestellt, der über einen Drehkranz 2 auf einem nicht dargestellten Panzerfahrzeug gelagert ist.In Fig. 1, a tank tower 1 is shown in section, which is mounted on a turntable 2 on an armored vehicle, not shown.

Im Panzerturm ist eine großkalibrige Rohrwaffe 3 ange­ordnet, deren Endstück 3a in den Kampfraum ragt, während das vordere Rohrende durch einen in nicht eigens darge­stellter Weise durch eine übliche Panzerung abgedeckten Schlitz 1a nach außen geführt ist.A large-caliber barrel weapon 3 is arranged in the turret, 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.

Die Rohrwaffe 3 ist mittels einer nachfolgend beschrie­benen das Rohr 3 umfassenden Schrägringlagerung im Panzerturm 1 aufgehängt. Die Schrägringlagerung besitzt einen ersten mit dem das Rohr 3 umfassenden Wiegenrohr 3b über Schraubverbindungen 4a verbundenen Anschluß­flansch 4, an dem über ein Kugel- oder Rollenlager 5 ein erster Lagerring 6 mit seinem einen Ende drehbar um die Rohrachse RA gelagert ist. An seinem anderen Ende ist der erste Lagerring 6 über ein weiteres Kugel- oder Rollenlager 8 drehbar um eine erste Drehachse D1 in einem Verbindungsring 7 gelagert, in dem dem ersten Lagerring 6 gegenüberliegend ein zweiter Lagerring über ein Kugel-oder Rollenlager 9 um die Drehachse D1 drehbar gelagert ist. Mit seinem anderen Ende ist der zweite Lagerring 10 über Kugel- oder Rollenlager 11 in einem Anschlußflansch 12 drehbar um eine zweite Drehachse D2 gelagert. Der Anschlußflansch 12 ist über Schraubverbin­dungen 12a mit der Schottwand 1b im Panzerturm 1 verbun­den.The barrel weapon 3 is suspended in the 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. At its other end, the first bearing ring 6 is rotatably supported by a further ball or roller bearing 8 about a first axis of rotation D1 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. With its other end, 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 via screw connections 12a to the bulkhead 1b in the turret 1.

Weiterhin ist der das Rohr 3 tragende Anschlußflansch 4 dadurch drehfest mit dem Panzerturm 1 verbunden, daß der hintere Abschnitt 3c des Wiegenrohres 3b als Vier­kant ausgeführt ist, der in einem Schlitz 1c in der Schottwand 1b geführt ist.Furthermore, 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.

Der Verbindungsring 7 ist ebenfalls gegenüber dem Pan­zerturm 1 drehfest, aber verschwenkbar, angeordnet, indem er ein Führungselement 16 besitzt, das in eine am Panzerturm 1 angeordnete mit einer in Längsrichtung verlaufenden Nut versehene Halterung 17 eintaucht.The connecting ring 7 is also rotatably but pivotably arranged with respect to the armored turret 1 by having a guide element 16 which is immersed in a holder 17 arranged on the armored turret 1 and provided with a longitudinally extending groove.

Am Verbindungsring 7 ist mindestens ein Antriebsmotor 13 angeordnet, dessen Abtriebswelle 13a ein Ritzel 14 antreibt, das unter der Wirkung einer Feder 15 in den Zwischenraum zwischen die beiden Lagerringe 6 und 10 eingedrückt wird derart, daß es in Verzahnungen 6a und 10a spielfrei eingreift, die an den beiden einander gegenüberliegenden Enden der beiden Lagerringe 6 und 10 angeordnet sind.At the connecting ring 7 at least one drive motor 13 is arranged, 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 the toothings 6a and 10a without play, which are arranged at the two opposite ends of the two bearing rings 6 and 10.

Die drei Drehachsen der Schrägringlagerung, nämlich die Rohrachse RA, die erste Drehachse D1 und die zweite Drehachse D2 schließen jeweils spitze Winkel α bzw. β miteinander ein. Die Drehachsen D1 und D2 schneiden sich in einem auf der Rohrachse RA liegenden Punkt P. Wie bekannte kinematische und geometrische Überlegungen zeigen, werden für den erstrebten Zweck die Winkel zwischen der ersten Drehachse und der Rohrachse sowie zwischen der zweiten Drehachse und der ersten Drehachse gleich groß gewählt. Unter diesen Bedingungen ist es möglich, durch gegensinniges Verdrehen der beiden Lager­ringe gegeneinander um gleiche Winkelbeträge eine in einer vertikalen Ebene ablaufende Schwenkbewegung der drehfest angeordneten Rohrwaffe 3 zu erzielen.The three axes of rotation of the inclined ring bearing, namely the pipe axis RA, the first axis of rotation D1 and the second axis of rotation D2 each form acute angles α and β with one another. The axes of rotation D1 and D2 intersect at a point P lying on the tube axis RA. As known kinematic and geometric considerations show, 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, by rotating the two bearing rings in opposite directions by the same angular amounts, to achieve a pivoting movement of the non-rotatably arranged gun 3 in a vertical plane.

Der Antrieb der beiden Lagerringe 6 und 10 in gegensin­niger Drehrichtung um gleiche Winkelbeträge erfolgt durch das in der radialen Lagerebene E des Verbindungs­ringes 7 zwischen den Lagerringen 6 und 10 angeordnete Ritzel 14. Die Verzahnungen 6a, 10a der Lagerringe 6, 10 sind mit gleicher Zähnezahl ausgebildet. Durch die Feder 15 wird dabei ein spielfreier Antrieb sicherge­stellt.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.

Das Verdrehen der beiden Antriebsringe 6 und 10 gegen­einander mittels des Antriebsmotors 13 bewirkt die Verschwenkung des Rohres 3, beispielsweise aus der in Fig. 1 dargestellten Stellung in die in Fig. 2 darge­stellte Stellung und umgekehrt. Dabei bewegt sich, wie aus den Zeichnungen ersichtlich, das Führungselement 16 in Längsrichtung in der Nut der Halterung 17.The rotation of the two drive rings 6 and 10 against each other by means of the drive motor 13 causes the tube 3 to pivot, for example from the position shown in FIG. 1 to the position shown in FIG. 2 and vice versa. As can be seen from the drawings, the guide element 16 moves in the longitudinal direction in the groove of the holder 17.

Selbstverständlich können die Antriebsringe 6 und 10 auch in anderer Weise als gemäß dem Ausführungsbeispiel nach Fig. 1 und 2 ausgebildet sein. So können sie bei­spielsweise die gegenläufigen Rotoren eines zwischen ihnen angeordneten direkt antreibenden Ringmotors sein, der als zweifacher elektrischer Torque-Ring-Motor ausge­bildet sein kann.Of course, the drive rings 6 and 10 can also be designed in a different manner than according to the embodiment of FIGS. 1 and 2. For example, they can be the counter-rotating rotors of a directly driving ring motor arranged between them, which can be designed as a double electrical torque ring motor.
