Definitions
- the invention relates to a detonator for low-swirl and for swirl projectiles with a recoil pin system consisting of two recoil pins coupled to one another via a ball, with a rotor or slide for receiving a detonator and with an inhibitor controlling the focus of the rotor or slide in a housing of the detonator.
- An igniter of the type mentioned is known from DE-PS 31 07 110.
- This is a safety device for a detonator of swirl projectiles with a recoil pin system, which is arranged within the rotor. Due to the launch acceleration of a projectile, a recoil bolt is moved backwards against the pressure of a spring. Due to the translational acceleration, the ball mounted on a cone of the second recoil bolt is pushed against an opposite cone of the first recoil bolt. The spring on the first recoil pin, via its cone and the ball used, locks the recoil pin system in the unlocked position, as a result of which the rotor is finally unlocked by the second recoil pin.
- this object is achieved in that a spring is provided, the first leg of which rests securely on the lower end of a cone of an axially movable recoil bolt and the second leg of which engages with its end on a pin or in a recess in the lateral surface of the slide or rotor.
- the spring is a leg spring bent around the bolt in a U-shape.
- the second leg of this spring lies against a shorter wall of the recess lying on the radius of the rotor in the rotational drive direction.
- a spring tensioning system is provided for the rotor arming on a detonator when the projectile is fired, which prestresses a spring which turns the rotor into the arming position after its release.
- the basic requirement of such a detonator is thus advantageously met in a simple manner, that no potential energy is used for the removal of the spark plug lock device.
- the spring is in the fully secured position when the system is secured and only receives its operating energy when the first spring arm is tensioned by the axial movement of the second recoil bolt.
- the rear-firing pin system 1 is mounted between two plates 14 and 15 arranged at a fixed distance from one another.
- This recoil pin system consists of a first recoil pin 5, which is inserted with its upper shaft 16 in the upper plate 14 and axially against a spring 17 supported on the lower plate 15.
- This recoil bolt 5 also has a cone 4, which is located between an upper collar 18 and a lower collar 19.
- another recoil pin 20 is inserted in the housing, which in turn is axially supported against a spring 21 supported on the lower plate 15.
- the two recoil bolts 5 and 20 are coupled to one another by a ball 11.
- a U-shaped leg spring 2 is inserted around a bolt 12 arranged in the housing, the first spring leg 3 of which rests with its end on the lower part of the cone 4 of the recoil pin 5 in the securing of the igniter.
- the second spring leg 6 of the leg spring lies in a recess 7 on the outer surface of the rotor 8. This spring leg 6 is supported in particular on the shorter wall 13 lying on the radius of the rotor 8.
- the rotor 8 also has a focus lock 9 and is in drive connection with an inhibitor 10 formed from a plurality of wheels.
- a slide can also be used.
- a correspondingly arranged pin can be provided, against which the spring leg 6 of the leg spring 2 rests.
- the leg spring 2 In securing the detonator, the leg spring 2 is not under tension and is protected against unintentional tension by securing the recoil pin system 1. There is therefore no spring force at the rotor 8. This meets STANAG 3525's requirement that no potential energy be used to remove the spark plug lock device.
- the recoil pin system 1 triggers and the recoil pin 5 biases the spring leg 3 of the U-shaped leg spring 2 as it moves downward through the cone 4.
- the spring leg 6 of the U-shaped leg spring 2 moves against the wall 13 in the recess 7 of the rotor 8. The rotor 8 is thus turned into the arming position, where it is fixed via the arming lock 9 becomes.
- the escapement 10 connected to the rotor controls the rotary movement of the rotor in the arming position.
- the inhibitor 10 itself consists of the armature 22, which is rotatably arranged on the shaft 23 and is in engagement with the star wheel 24.
- the pinion 25, which is rotationally fixed on the same shaft with the star wheel 24, meshes with the intermediate wheel 26, which in turn is arranged on the same shaft with the second pinion 27 in a rotationally fixed manner.
- the pinion 27 is operatively connected to the toothed segment 28, as a result of which the disk 29, which is rotationally fixed on the same shaft as the toothed segment, performs a limited rotational movement.
- the rotor 8 When the disk 29 rotates, the rotor 8 is uncoupled from the inhibitor mechanism 10 when the flattened area of the disk 29 is above the recess 30 of the rotor. The rotor then swivels into its focus position, the spring leg 6 serving as the drive.

Abstract
Mit der Erfindung wird ein Federspannsystem für die Rotorscharfstellung von einem Zünder beim Abschuß eines Geschosses vorgestellt. In der Sicherstellung des Zünders ist eine mit dem Rotor (8) in Eingriff befindliche Feder (2) ungespannt und gegen unbeabsichtigte Spannung geschützt. Erst bei Abschuß des Zünders mit einem Geschoß wird ein Schenkel (3) der Feder (2) durch einen Konus (4) eines Rückschießbolzens (5) vorgespannt. Nach der Freigabe des Rotors (8) bewegt der zweite Schenkel (6) der Feder (2) den Rotor (8) in die Scharfstellung.With the invention, a spring tensioning system for rotor focusing by an igniter is presented when a projectile is fired. When the igniter is secured, a spring (2) which is in engagement with the rotor (8) is not under tension and is protected against unintentional tension. Only when the detonator is fired with a projectile is a leg (3) of the spring (2) biased by a cone (4) of a recoil bolt (5). After the rotor (8) has been released, the second leg (6) of the spring (2) moves the rotor (8) into the arming position.
Description
Die Erfindung betrifft einen Zünder für drallarme und für Drallgeschosse mit einem Rückschießbolzensystem aus zwei über eine Kugel miteinander gekoppelte Rückschießbolzen, mit einem Rotor oder Schieber zur Aufnahme eines Detonators und mit einem die Scharfstellung des Rotors oder Schiebers steuernden Hemmwerk in einem Gehäuse des Zünders.The invention relates to a detonator for low-swirl and for swirl projectiles with a recoil pin system consisting of two recoil pins coupled to one another via a ball, with a rotor or slide for receiving a detonator and with an inhibitor controlling the focus of the rotor or slide in a housing of the detonator.
Ein Zünder der eingangs genannten Art ist durch die DE-PS 31 07 110 bekannt. Hierbei handelt es sich um eine Sicherheitsvorrichtung für einen Zünder von Drallgeschossen mit einem Rückschießbolzensystem, welches innerhalb des Rotors angeordnet ist. Durch die Abschußbeschleunigung eines Geschosses wird ein Rückschießbolzen gegen den Druck einer Feder nach hinten bewegt. Die an einem Konus des zweiten Rückschießbolzens gelagerte Kugel wird aufgrund der Translationsbeschleunigung an einen gegenläufigen Konus des ersten Rückschießbolzens geschoben. Die Feder am ersten Rückschießbolzen bewirkt über dessen Konus und die eingesetzte Kugel eine Arretierung des Rückschießbolzensystems in entsicherter Position, wodurch der Rotor durch den zweiten Rückschießbolzen schließlich entriegelt ist.An igniter of the type mentioned is known from DE-PS 31 07 110. This is a safety device for a detonator of swirl projectiles with a recoil pin system, which is arranged within the rotor. Due to the launch acceleration of a projectile, a recoil bolt is moved backwards against the pressure of a spring. Due to the translational acceleration, the ball mounted on a cone of the second recoil bolt is pushed against an opposite cone of the first recoil bolt. The spring on the first recoil pin, via its cone and the ball used, locks the recoil pin system in the unlocked position, as a result of which the rotor is finally unlocked by the second recoil pin.
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, die grundsätzliche Forderung eines solchen Zünders zu erfüllen, keine potentielle Energie für die Beseitigung der Zündkettensperreinrichtung zu verwenden.Starting from this prior art, it is an object of the invention to meet the basic requirement of such a detonator not to use any potential energy for the removal of the spark plug lock device.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß eine Feder vorgesehen ist, deren erster Schenkel in Sicherstellung am unteren Ende eines Konus eines axial bewegbaren Rückschießbolzens anliegt und deren zweiter Schenkel mit seinem Ende an einem Stift oder in einer Ausnehmung in Mantelfläche des Schiebers oder Rotors eingreift.According to the invention, this object is achieved in that a spring is provided, the first leg of which rests securely on the lower end of a cone of an axially movable recoil bolt and the second leg of which engages with its end on a pin or in a recess in the lateral surface of the slide or rotor.
Dabei ist in vorteilhafter Ausführung der Erfindung die Feder eine um den Bolzen U-förmig gebogene Schenkelfeder. Der zweite Schenkel dieser Feder liegt gegen eine auf dem Radius des Rotors liegende, kürzere Wand der Ausnehmung in Drehantriebsrichtung an.In an advantageous embodiment of the invention, the spring is a leg spring bent around the bolt in a U-shape. The second leg of this spring lies against a shorter wall of the recess lying on the radius of the rotor in the rotational drive direction.
Durch diese Erfindung wird für die Rotorscharfstellung an einem Zünder beim Abschuß des Geschosses ein Federspannsystem zur Verfügung gestellt, welches eine Feder vorspannt, die den Rotor nach seiner Freigabe in die Scharfstellung dreht. Damit wird in vorteilhaft einfacher Weise die grundsätzliche Forderung an einem solchen Zünder erfüllt, keine potentielle Energie für die Beseitigung der Zündkettensperreinrichtung zu verwenden. Die Feder befindet sich in der Sicherstellung des Systems in vollkommen entspannter Lage und erhält erst dann ihre Betriebsenergie, wenn durch die axiale Bewegung des zweiten Rückschießbolzens der erste Federarm gespannt wird.By means of this invention, a spring tensioning system is provided for the rotor arming on a detonator when the projectile is fired, which prestresses a spring which turns the rotor into the arming position after its release. The basic requirement of such a detonator is thus advantageously met in a simple manner, that no potential energy is used for the removal of the spark plug lock device. The spring is in the fully secured position when the system is secured and only receives its operating energy when the first spring arm is tensioned by the axial movement of the second recoil bolt.
In der Zeichnung ist ein Beispiel der Erfindung dargestellt. Es zeigen:
- Fig. 1 das Rückschießbolzensystem innerhalb des Zündergehäuses in Ansicht;
- Fig. 2 den Zünder in der Ansicht nach der Schnittlinie II-II in Fig. 1.
- Figure 1 shows the rear-firing pin system within the igniter housing in view.
- 2 shows the igniter in the view along the section line II-II in FIG. 1.
Zwischen zwei im festen Abstand zueinander angeordneten Platten 14 und 15 ist das Rückschießbolzensystem 1 gelagert. Dieses Rückschießbolzensystem besteht aus einem ersten Rückschießbolzen 5, der mit seinem oberen Schaft 16 in der oberen Platine 14 eingesetzt ist und axial gegen eine sich an der unteren Platine 15 abstützende Feder 17 ansteht. Dieser Rückschießbolzen 5 weist ferner einen Konus 4 auf, der sich zwischen einem oberen Bund 18 und einem unteren Bund 19 befindet. Parallel zu diesem Rückschießbolzen 5 ist im Gehäuse ein weiterer Rückschießbolzen 20 eingesetzt, welcher wiederum axial gegen eine sich an der unteren Platine 15 abstützende Feder 21 abstützt.The rear-firing pin system 1 is mounted between two
Die beiden Rückschießbolzen 5 und 20 sind durch eine Kugel 11 miteinander gekoppelt. Um einen im Gehäuse angeordneten Bolzen 12 ist eine U-förmig gebogene Schenkelfeder 2 eingesetzt, deren erster Federschenkel 3 in der Sicherstellung des Zünders mit seinem Ende am unteren Teil des Konus 4 des Rückschießbolzens 5 anliegt. Der zweite Federschenkel 6 der Schenkelfeder liegt in einer Ausnehmung 7 an der Mantelfläche des Rotors 8 an. Dieser Federschenkel 6 stützt sich dabei insbesondere an der kürzeren, auf dem Radius des Rotors 8 liegenden Wand 13 ab. Der Rotor 8 besitzt ferner eine Scharfstellarretierung 9 und steht mit einem aus mehreren Rädern gebildeten Hemmwerk 10 in Antriebsverbindung.The two
Anstelle des Rotors 8 kann ebenso auch ein Schieber eingesetzt sein. Außerdem kann auch anstelle der Ausnehmung 7 am Rotor bzw. an einem Schieber 8 ein entsprechend angeordneter Stift vorgesehen sein, gegen den der Federschenkel 6 der Schenkelfeder 2 anliegt.Instead of the
In der Sicherstellung des Zünders ist die Schenkelfeder 2 ungespannt und wird durch die Absicherung des Rückschießbolzensystems 1 gegen eine unbeabsichtigte Spannung geschützt. Es liegt demzufolge keinerlei Federkraft am Rotor 8 an. Damit wird die Forderung der STANAG 3525 erfüllt, keine potentielle Energie für die Beseitigung der Zündkettensperreinrichtung zu verwenden.In securing the detonator, the leg spring 2 is not under tension and is protected against unintentional tension by securing the recoil pin system 1. There is therefore no spring force at the
Bei einer axialen Beschleunigung bei Abschuß des Zünders mit einem Geschoß löst das Rückschießbolzensystem 1 aus und der Rückschießbolzen 5 spannt bei seiner Abwärtsbewegung durch den Konus 4 den Federschenkel 3 der U-förmigen Schenkelfeder 2 vor. Nach der Freigabe des Rotors 8 durch die übrigen Sicherungselemente bewegt sich der Federschenkel 6 der U-förmigen Schenkelfeder 2 gegen die Wand 13 in der Ausnehmung 7 des Rotors 8. Damit wird der Rotor 8 in die Scharfstellung gedreht, wo er über die Scharfstellarretierung 9 fixiert wird.With an axial acceleration when the detonator is fired with a projectile, the recoil pin system 1 triggers and the
Das mit dem Rotor verbundene Hemmwerk 10 steuert die Drehbewegung des Rotors in Scharfstellung.The
Das Hemmwerk 10 selbst besteht aus dem Anker 22, der auf der Welle 23 drehbar angeordnet ist und mit dem Sternrad 24 in Eingriff steht. Das mit dem Sternrad 24 auf gleicher Welle drehfeste Ritzel 25 kämmt mit dem Zwischenrad 26, welches wiederum auf einer gleichen Welle mit dem zweiten Ritzel 27 drehfest angeordnet ist. Das Ritzel 27 ist mit dem Zahnsegment 28 wirkverbunden, wodurch die auf gleicher Welle mit dem Zahnsegment drehfeste Scheibe 29 eine begrenzte Drehbewegung durchführt. Bei Drehung der Scheibe 29 wird der Rotor 8 von dem Hemmwerk 10 entkuppelt, wenn der abgeflachte Bereich der Scheibe 29 über der Ausnehmung 30 des Rotors steht. Danach schwenkt der Rotor in seine Scharfstellung, wobei der Federschenkel 6 als Antrieb dient.The
Mit diesem Zünder wird insgesamt mehr Sicherheit erzielt, da im Sicherheitszustand keine vorgespannte Rotordrehfeder vorhanden ist.Overall, more safety is achieved with this igniter, since there is no preloaded rotor torsion spring in the safety state.
