Description

Die vorliegende Erfindung bezieht sich auf eine Arretiereinrichtung zur Sicherung einer eingestellten Position an einer Vorrichtung, beispielsweise einer Justierposition an einer mechanischen Vorrichtung, welche schwenkbar auf einer Unterlage gelagert ist und wobei zur Ein- und Feststellung der Justierposition bspw. ein drehbar gelagertes, über ein Getriebe mit der Vorrichtung in Wirkverbindung stehendes Handrad arretiert werden kann. Eine solche Vorrichtung ist z.B. aus der CH-A-281164 bekannt.The present invention relates to a locking device for securing a set position on a device, for example an adjustment position on a mechanical device, which is pivotally mounted on a base and, for example, for setting and determining the adjustment position handwheel that is operatively connected to the device can be locked. Such a device is e.g. known from CH-A-281164.

Die Anordnung von Arretiervorrichtungen zur Sicherung einer Ausrichtposition (Justierposition) eines Geschützes, ist an sich bereits bekannt (z.B aus der obenerwähnten CH-A-281164). Die stufenlos und beidseitig wirksame, sowie spielfreie Sicherung der Justierposition an einem solchen Geschütz war bisher jedoch problematisch.The arrangement of locking devices for securing an alignment position (adjustment position) of a gun is already known per se (e.g. from the above-mentioned CH-A-281164). Up to now, the continuously and bilaterally effective and play-free securing of the adjustment position on such a gun was problematic.

Eine Schiesseinrichtung, wie sie durch ein Geschütz dargestellt ist, soll in beliebiger, stufenloser Elevationsstellung mit einfacher Bedienung vom Operateur, bspw. für Justierzwecke, arretiert werden können. Die Justierung bezieht sich in diesem Fall auf die Ausrichtung der optischen Visierlinie zur Rohrachse der Waffe. Um die diffizile Einstelloperation durchzuführen, muss eine präzise, spielfreie, das heisst, sicher wirkende Arretierung gewährleistet sein. Weiterhin soll die Arretierung in beiden Drehrichtungen des Handantriebes voll worksam sein. In gelöster Stellung des Handrades muss ein reibungsloser Freilauf desselben gewährleistet sein.A shooting device, as represented by a gun, should be able to be locked in any stepless elevation position with simple operation by the operator, for example for adjustment purposes. In this case, the adjustment relates to the alignment of the optical line of sight with the barrel axis of the weapon. In order to carry out the difficult adjustment operation, a precise, play-free, that is to say a safe-acting locking device must be guaranteed. Furthermore, the lock should be fully working in both directions of rotation of the manual drive. When the handwheel is released, the freewheel must run smoothly.

Durch diese speziellen Forderungen an eine Arretierung erwachsen jedoch weitere Probleme, zumal sich durch die Uebersetzung zum Handbetrieb der Elevationswinkel auf N(mal)360° erweitert, die Lager durch die Arretierung nicht belastet werden dürfen (spannungsfreie Arretierung) und die Bedienung vorzugsweise mit einer Drehbewegung mit gleichbleibendem Drehmoment über den ganzen Freilauf erfolgen soll.However, these special requirements for a lock cause further problems, especially as the translation to manual operation increases the elevation angle to N (times) 360 °, the bearings must not be loaded by the lock (tension-free lock) and the operation preferably with a rotary movement with constant torque over the entire freewheel.

Bekannt ist beispielsweise die Anordnung einer Lamellen-Bremse zwischen einem stationären, unbeweglichen Teil der Schiesseinrichtung, wie beispielsweise einer Lafette bzw. einem Gehäuse und einem drehbar gelagerten Handrad, um mit Hilfe der Lamellenbremse die Position des Handrades und damit die einmal eingestellte Justierposition der Schiesseinrichtung zu arreitieren bzw. zu fixieren. Die bisher bekannte Anordnung einer Lamellen-Bremse zum Arretieren bzw. Fixieren einer einmal eingestellten Justierposition an einer Schiesseinrichtung war bisher jedoch nicht zufriedenstellend. Weiterhin war der konstruktive Aufwand und Platzbedarf für die Anordnung einer Lamellen-Bremse verhältnismässig hoch. Gerade bei einem nachträglichen Einbau einer Arretiereinrichtung, können bezüglich Platzbedart grosse Sachzwänge auftreten, sodass konstrucktive Lösungen, die einen geringen Platzbedarf aufweisen, von Vorteil sind.It is known, for example, the arrangement of a multi-disc brake between a stationary, immovable part of the shooting device, such as, for example, a mount or a housing and a rotatably mounted handwheel, in order to use the multi-disc brake to position the handwheel and thus the once set adjustment position of the shooting device argue or fix. However, the previously known arrangement of a multi-disc brake for locking or fixing a once-adjusted adjustment position on a shooting device has so far not been satisfactory. Furthermore, the design effort and space required for the arrangement of a multi-disc brake was relatively high. Especially when retrofitting a locking device, large constraints can arise with regard to space requirements, so that constant pressure solutions that require little space are advantageous.

Der vorliegenden Erfindung liegt nunmehr die Aufgabe zugrunde, eine Arretiervorrichtung zur Sicherung einer eingestellten Position an einer mechanischen Vorrichtung der vorbezeichneten Art zu schaffen, mit welcher insbesondere die den bisher bekannten, an Schiesseinrichtungen angeordneten Arretiervorrichtungen anhaftenden vorbeschrieben Nachteil vermieden werden.The present invention is based on the object of creating a locking device for securing a set position on a mechanical device of the aforementioned type, with which in particular the previously described disadvantage associated with locking devices arranged on shooting devices is avoided.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass ein Verstellmechanismus, bspw, das tellerförmig ausgebildete Handrad, einen mit demselben fest verbundenen, konzentrisch zu einer Drehachse des Verstellmechanismus angeordneten zylinderförmigen Ring aufweist, an dessen beiden gekrümmten Seiten, d.h., jeweils an je einer Seite je eine Klemmbacke angeordnet ist, welche ihrerseits Bestandteile einer fest mit dem Gehäuse verbundenen, sich zum Ring verschieblich selbsteinstellende Klemmeinrichtung bilden.According to the invention, the object is achieved in that an adjusting mechanism, for example the plate-shaped handwheel, has a cylindrical ring which is fixedly connected to the same and is arranged concentrically to an axis of rotation of the adjusting mechanism, on the two curved sides thereof, that is, one on each side Clamping jaw is arranged, which in turn form part of a clamping device which is fixedly connected to the housing and which is displaceable to the ring and is self-adjusting.

In einer bevorzugten Ausführungsform ist am Gehäuse der Vorrichtung eine Ausnehmung zur Aufnahe eines Einsatzes vorgesehen, welcher mit dem Gehäuse fest verbunden ist und in welchem die zwei Klemmbacken aufweisende Klemmeinrichtung angeordnet ist. Weiterhin ist hierbei der Einsatz in bevorzugter Weise im näheren Bereich des Umfanges des Handrades in einem radialen Abstand von der Drehachse desselben in der Ausnehmung des besagten Gehäuses angeordnet word1 n.In a preferred embodiment, a recess is provided on the housing of the device for receiving an insert, which is firmly connected to the housing and in which the clamping device having two jaws is arranged. Furthermore, the insert is preferably arranged in the vicinity of the circumference of the handwheel at a radial distance from the axis of rotation thereof in the recess of said housing.

Die beiden Klemmbacken der Klemmeinrichtung sind in einer U-förmigen Ausnehmung-in der Längsrichtung derselben-derat hin- und herbeweglich geführt, dass die Klemmbacken in seitlicher Richtung keine Bewegung ausüben können.The two clamping jaws of the clamping device are guided back and forth in a U-shaped recess — in the longitudinal direction of the same — such that the clamping jaws cannot move laterally.

Bei einer weiterhin vorteilhaften Ausgestaltung der Erfindung weist die an der Aussenseite des Ringes angeordnete Klemmbacke eine dem äusseren Umfang des Ringes angepasste, konkav gewölbte Anpressfläche und die an der Innenseite des Ringes angeordnete Klemmbacke eine dem inneren Umfang des Ringes angepasste, konvex gewölbte Anpressfläche auf.In a further advantageous embodiment of the invention, the clamping jaw arranged on the outside of the ring has a concavely curved pressing surface adapted to the outer circumference of the ring and the clamping jaw arranged on the inside of the ring has a convex curved pressing surface adapted to the inner circumference of the ring.

Die Klemmeinrichtung weist in einer bevorzugten Ausgestaltung eine auf Gleitlagern drehbar gelagerte Betätigungswelle auf, welche mit einer elektrisch oder manuell betätigten Vorrichtung in Antriebsverbindung steht, um der Betätigungswelle eine Drehung in beiden Drehrichtungen zu verleihen. Weiterhin weist die Betätigungswelle einen zylindrischen Abschnitt mit einem Aussengewinde auf, welches mit einem Innengewinde einer der Innenseite des Ringes zugeordneten Klemmbacke im Eingriff steht und wobei andererseits die Betätigungswelle durch eine Bohrung einer der Aussenseite des Ringes zugeordneten Klemmbacke hindurchgeführt ist.In a preferred embodiment, the clamping device has an actuating shaft which is rotatably mounted on slide bearings and which is in drive connection with an electrically or manually actuated device in order to give the actuating shaft a rotation in both directions of rotation. Furthermore, the actuating shaft has a cylindrical section with an external thread, which is in engagement with an internal thread of a clamping jaw assigned to the inside of the ring and, on the other hand, the actuating shaft is passed through a bore of a clamping jaw assigned to the outside of the ring.

Ausgehend von der auf die Betätigungswelle aufgesetzten, der Aussenseite des Ringes zugeordneten Klemmbacke sind auf die Betätigungswelle Tellerfedern, ein Stützring für die Tellerfedern und eine mit der Betätigungswelle fest verbundene Buchse auf die Welle aufgezogen.Starting from the clamping jaw placed on the actuating shaft and assigned to the outside of the ring, plate springs, a support ring for the plate springs and a bushing which is firmly connected to the actuating shaft are mounted on the shaft on the actuating shaft.

An einem aus dem Einsatz herausragenden Ende der Buchse ist ein Stift quer zu derselben verlaufend angeordnet, welcher über den Umfang der besagten Buchse mit einem Ende herausragt und mit diesem Ende in einer kreisbogenförmigen Ausnehmung des Einsatzes eine Drehbewegung in beiden Drehrichtungen in einem vorbestimmten Winkelbereich bei der Betätigung der Klemmeinrichtung ausübt. Der Winkelbereich erstreckt sich von einem ersten Anschlag bis zu einem zweiten Anschlag, welche in der kreisbogenförmgien Ausnehmung des Einsatzes angeordnet sind.At one end of the socket protruding from the insert, a pin is arranged running transversely to the same, which over the Extends circumference of said socket with one end and with this end in a circular recess of the insert rotates in both directions of rotation in a predetermined angular range when actuating the clamping device. The angular range extends from a first stop to a second stop, which are arranged in the arcuate recess of the insert.

Anschliessend wird nun anhand der nachfolgend aufgeführten Zeichnungen die Erfindung am Beispiel der vorerwähnten Schiesseinrichtung, also an einem Geschütz, eingehend diskutiert.The invention will now be discussed in detail with reference to the drawings shown below using the example of the aforementioned shooting device, that is to say on a gun.

Das Handrad 3 ist tellerförmig ausgebildet und weist auf seiner Innenseite eine mit demselben fest verbundenen, konzentrisch zur Drehachse 4 desselben angeordneten zylindrischen Ring 14 auf, an dessen beiden Seiten 19 und 20 jeweils eine Klemmbacke 8 und 9 angeordnet ist. Diese Klemmbacken sind Bestandteile einer Klemmeinrichtung 10, die weiter unten im Detail beschrieben ist.The handwheel 3 is plate-shaped and has on its inside a cylindrical ring 14 which is fixedly connected to it and is arranged concentrically to the axis of rotation 4 thereof, on the two sides 19 and 20 of which a clamping jaw 8 and 9 is arranged. These jaws are part of a clamping device 10, which is described in detail below.

In einem vorbestimmten Radialen Abstand von der Drehachse 4 des Handrades 3 ist im näheren Bereich des Umfanges desselben an dem Gehäuse 2 eine Ausnehmung 5 zur Aufnahme eines Einsatzes 6 vorgesehen, welcher mit Hilfe von Schrauben 7 mit dem Gehäuse 2 fest verbunden ist und in welchem eine zwei Klemmbacken 8 und 9 aufweisende Klemmeinrichtung 10 angeordnet ist. Siehe unter anderem Figur 4.At a predetermined radial distance from the axis of rotation 4 of the handwheel 3, a recess 5 for receiving an insert 6 is provided in the closer region of the circumference thereof on the housing 2, which is firmly connected to the housing 2 by means of screws 7 and in which one two clamping jaws 8 and 9 having clamping device 10 is arranged. See, inter alia, Figure 4.

Das Handrad 3 weist auf seiner Innenseite eine ringförmige Ausnehmung 13 auf, welche die über die Oberfläche des Gehäuses 2 herausragenden Klemmbacken 8 und 9 der Klemmeinrichtung 10 überdeckt. An der Aussenseite des Handrades 3 ist in bekannter Art und Weise eine Kurbel 15 vorgesehen.The handwheel 3 has an annular recess 13 on its inside, which covers the clamping jaws 8 and 9 of the clamping device 10 which protrude beyond the surface of the housing 2. On the outside of the handwheel 3, a crank 15 is provided in a known manner.

Die beiden Klemmbacken 8 und 9 der Klemmeinrichtung 10 sind gemäss der Figur 6 in einer U-förmigen Ausnehmung 16-in der Längsrichtung derselben-derart hin- und herbeweglich geführt, dass die beiden an der Innenseite 19 und der Aussenseite 20 des Ringes 14 angeordneten Klemmbacken 8 und 9 in seitlicher Richtung keine Bewegung ausüben können. Mit Hilfe der Klemmeinrichtung 10 werden diese gegen die Innenseite 19 und die Aussenseite 20 des Ringes 14 gepresst und auf diese Weise durch Reibungsschluss mit dem Ring 14 fest verbunden. Auch die Ausbildung von den Klemmbacken und dem zylinderförmigen Ring zur Erzielung eines Formschlusses kann vorteilhaft sein. Eine solche Massnahme ist das Anbringen einer Verzahnung, wobei allerdings die bei einem Reibungsschluss gegebene stufenlose Einstellbarkeit aufgegeben wird. Wird die Verzahnung eher grob gewählt, so können die Rastpositionen für ein Verstellmass herangezogen werden; eine eher feine Verzahnung dient lediglich einer Erhöhung der Arretierkraft mittels Formschluss. Auch der Reibungsschluss kann durch ausgesuchte Materialpaarungen erhöht werden. Solche Paarungen sind bspw. erzielbar durch Verwendung von Haftbelägen auf den Klemmflächen der Backen und/oder auf den beiden gekrümmten Seiten des zylinderförmigen Ringes.According to FIG. 6, the two clamping jaws 8 and 9 of the clamping device 10 are guided to and fro in a U-shaped recess 16 — in the longitudinal direction thereof — such that the two clamping jaws arranged on the inside 19 and the outside 20 of the ring 14 8 and 9 cannot move laterally. With the help of the clamping device 10, these are pressed against the inside 19 and the outside 20 of the ring 14 and in this way are firmly connected to the ring 14 by frictional engagement. The formation of the clamping jaws and the cylindrical ring to achieve a positive fit can also be advantageous. One such measure is the fitting of a toothing, however the stepless adjustability given in the case of a frictional engagement is given up. If the toothing is chosen rather roughly, the locking positions can be used for an adjustment dimension; a rather fine toothing only serves to increase the locking force by means of a positive fit. The frictional engagement can also be increased by selected material combinations. Such pairings can be achieved, for example, by using adhesive coverings on the clamping surfaces of the jaws and / or on the two curved sides of the cylindrical ring.

Ergänzend ist zu erwähnen, dass gemäss Figur 4 die an der Aussenseite 20 des Ringes 14 angeordnete Klemmbacke 8 eine dem äusseren Umfang des Ringes 14 angepasste, konkav gewölbte Anpressfläche 21 und die an der Innenseite des Ringes angeordnete Klemmbacke 9 eine dem inneren Umfang des Ringes 14 angepasste, konvex gewölbte Anpressfläche 22 aufweist.It should also be mentioned that according to FIG 4 the clamping jaw 8 arranged on the outside 20 of the ring 14 has a concavely curved pressing surface 21 adapted to the outer circumference of the ring 14 and the clamping jaw 9 arranged on the inside of the ring has a convex curved pressing surface 22 adapted to the inner circumference of the ring 14.

Die bereits erwähnte Klemmeinrichtung 10 weist eine auf Gleitlagern 17 und 18 drehbar gelagerte Betätigungswelle 12 auf, welche mit einer elektrisch oder manuell betätigten Vorrichtung 11 derart in Antriebsverbindung steht, dass derselben eine Drehung im Uhrzeigersinn und eine andere Drehung im entgegengesetzten Uhrzeigersinn verliehen werden kann.The clamping device 10 already mentioned has an actuating shaft 12 which is rotatably mounted on slide bearings 17 and 18 and which is in drive connection with an electrically or manually operated device 11 in such a way that it can be given a rotation in the clockwise direction and another rotation in the counterclockwise direction.

Die Betätigungswelle 12 weist einen zylindrischen Abschnitt 23 mit einem Aussengewinde 24 auf, welche mit einem an der Klemmbacke 9 angeordneten Innengewinde 25 im Eingriff steht. Die andere Klemmbacke 8 ist dagegen mit einer Bohrung 26 versehen, durch welche die Betätigungswelle 12 hindurchgeführt ist.The actuating shaft 12 has a cylindrical section 23 with an external thread 24, which is in engagement with an internal thread 25 arranged on the clamping jaw 9. The other jaw 8, however, is provided with a bore 26 through which the actuating shaft 12 is passed.

Ausgehend von der auf der Betätigungswelle 12 gelagerten Klemmbacke 8 sind auf der Welle Tellerfedern 30, ein Stützring 29 für die Tellerfedern sowie eine mit der Betätigungswelle 12 unverdrehbar fest verbundenen Büchse 28 aufgezogen worden.Starting from the clamping jaw 8 mounted on the actuating shaft 12, plate springs 30, a support ring 29 for the plate springs and a bushing 28 which is non-rotatably connected to the actuating shaft 12 have been mounted on the shaft.

Gemäss den Figuren 3 und 5 ist an dem aus dem Einsatz 6 herauszeigenden Ende der Büchse 28 ein Stift 31 quer zu derselben angeordnet, welcher über den Umfang der Büchse 28 hinausragt und mit dem herausragenden Ende 32 der Büchse in einer kreisbogenförmigen Ausnehmung 33 des Einsatzes 6 (siehe Fig. 1), eine Drehbwegung in einem vorbestimmten Winkelbereich bei der Betätigung der Klemmeinrichtung 10 ausübt. Der Winkelbereich erstreckt sich gemäss der Figur 3 von einem ersten Anschlag 34 bis zu einem zweiten Anschlag 35, welche von einem achsparallel zur Betätigungswelle 12 in eine Bohrung 36 des Einsatzes 6 eingesetzten Stift 37 gebildet werden.According to FIGS. 3 and 5, a pin 31 is arranged transversely to the end of the sleeve 28 pointing out of the insert 6, which pin projects beyond the circumference of the sleeve 28 and with the protruding end 32 of the sleeve in an arcuate recess 33 of the insert 6 (see FIG. 1), a rotational movement in a predetermined angular range when the clamping device 10 is actuated. According to FIG. 3, the angular range extends from a first stop 34 to a second stop 35, which are formed by a pin 37 inserted into a bore 36 of the insert 6 parallel to the actuating shaft 12.

An dem äusseren Ende der Büchse 28 ist weiterhin koaxial zur Drehachse der Betätigungswelle 12 ein Sechskant 38 befestigt, welches in einer nicht dargestellten Art und Weise mit einem Sechskantschlüssel der bspw, elektrisch betriebenen Vorrichtung 11 zum Betätigen der Welle 12 bzw. zum Drehen der Welle 12 in beiden Drehrichtungen innerhalb des bereits erwähnten Winkelbereichs zwischen einem ersten Anschlag 34 und einem zweiten Anschlag 35 in Antriebsverbindung steht. Der Sechskantschlüssel kann auch von Hand betätigt werden, notfalls kann die Betätigung z.B. auch mit einem passenden Gabelschlüssel durchgeführt werden.At the outer end of the sleeve 28, a hexagon 38 is furthermore fastened coaxially to the axis of rotation of the actuating shaft 12, which in a manner not shown with a hexagon key of the, for example, electrically operated device 11 for actuating the shaft 12 or for rotating the shaft 12 is in drive connection in both directions of rotation within the already mentioned angular range between a first stop 34 and a second stop 35. The hexagon key can also be operated by hand, if necessary the operation can be e.g. can also be carried out with a suitable open-ended wrench.

Die Arbeitsweise der vorbeschriebenen Arretiervorrichtung 1 ist wie folgt:The operation of the locking device 1 described above is as follows:

Um eine vorangegangene Arretierung zu lösen, wird die Betätigungswelle 12 der Klemmeinrichtung 10 in einfacher Weise mit Hilfe der Vorrichtung 11 entgegen dem Uhrzeigersinn bis zum zweiten Anschlag 35 gedreht. Beim Lösen der Klemmbacken geschieht dann folgendes: Während dem Drehen der Betätigungswelle 12 wird der zylindrische Abschnitt 23 gegen die Klemmbacke 8 bewegt. Dabei wird das für eine sichere Klemmwirkung vorgesehene Achsialspiel zwischen dem zylindrischen Abschnitt 23 und der Klemmbacke 8 aufgehoben und die Klemmbacke sukzessive entgegen die Federkraft der Tellerfedern 30 bewegt. Dabei wird die Einbaulänge des Federpaketes verringert und der Federdruck steigt etwas an, allerdings so gering, dass das zusätzliche Betätigungsmoment (bspw, bei einem elektrischen Antrieb) vernachlössigbar ist. Die aschiale Verschiebbarkeit der Klemmeinrichtung 10 ist nun praktisch aufgehoben, die Klemmbacken 8 und 9 stehen nun am Gehäuse 2 bzw. am Einsatz 6 an, damit ist ein (berührungsfreier) Freilauf des Ringes 14 zwischen den beiden Klemmbacken hindurch gewährleistet. In geöffnetem Zustand werden die gespreizten Klemmbacken 8 und 9 achsial in der Lagerung positioniert, womit ein freies Spiel zu dem zu blockierenden Ring 14 gerantiert ist.In order to release a previous locking, the actuating shaft 12 of the clamping device 10 is rotated counterclockwise in a simple manner with the aid of the device 11 up to the second stop 35. The following then occurs when the clamping jaws are released: While the actuating shaft 12 is rotating, the cylindrical section 23 is moved against the clamping jaw 8. The axial play provided for a secure clamping action between the cylindrical section 23 and the clamping jaw 8 is canceled and the clamping jaw is successively moved against the spring force of the plate springs 30. The installation length of the spring assembly is reduced and the spring pressure increases somewhat, but so low that the additional actuation torque (for example, in the case of an electric drive) is negligible. The aschial displaceability of the clamping device 10 is now practically eliminated, the clamping jaws 8 and 9 are now in contact with the housing 2 and the insert 6, respectively, so that a (contact-free) free movement of the ring 14 between the two clamping jaws is ensured. In the open state, the spread jaws 8 and 9 are positioned axially in the bearing, with which a free play to the ring 14 to be blocked is guaranteed.

Nach erfolgter Einstellung der Schiesseinrichtung mit Hilfe des Handrades 3 in die gewünschte Position (Elevationsposition) wird die Arretierung und Fixierung der eingestellten Position dadurch bewerkstelligt, dass das Handrad 3 über den Ring 14 und die Klemmbacken 8 und 9 mit dem gegenüber dem Handrad 3 stationären Teil oder einem Gehäuse der Schiesseinrichtung fest verbunden wird.After setting the shooting device with the help of the handwheel 3 in the desired position (elevation position), the locking and fixing of the set position is accomplished in that the handwheel 3 via the ring 14 and the clamping jaws 8 and 9 with the part that is stationary relative to the handwheel 3 or a housing of the shooting device is firmly connected.

Zwecks Arretierung wird die Betätigungswelle 12 der Klemmeinrichtung 10 nun mit Hilfe der Vorrichtung 11 im Uhrzeigersinn bis zu einem ersten Anschlag 34 verdreht und übt hierbei entgegen der auf die Klemmbacke 8 wirkenden Kraft der vorgespannten Tellerfedern 30 über die Schraubverbindung 24, 25 zwischen der Betätigungswelle 12 und der Klemmbacke 9 eine beispielsweise 1000 N übersteigende Zugkraft auf die Klemmbacke 9 aus, welche zwischen den beiden Klemmbacken 8 und 9 einerseits, die so in ihrer achsialen Lage definiert sind, und dem mit dem Handrad 3 fest verbundenen Ring 14 andererseits einen festen Reibungsschluss oder Formschluss bewirkt, wodurch das Handrad 3 in der gewünschten Weise in seiner Position arretiert und fixiert ist. Das Spiel in der Arretiervorrichtung ist bspw. in der Grösse von 0.1 mm angenommen. Die Uebertragung dieses Spiels auf das Handrad der diskutierten Schiesseinrichtung entspricht dann einem Winkel von ungefähr 0.1° (Grad), welches Winkelspiel sich durch die Uebersetzung auf die Höhenkoordinate (gemäss diesem Beispiel von 1:140) auf ungefähr 2,3" (Sekunden) verringert, was auch für präzise Positionsmessungen vernachlässigbar ist.For the purpose of locking, the actuating shaft 12 of the clamping device 10 is now rotated clockwise with the aid of the device 11 up to a first stop 34 and in this case exercises against the force acting on the clamping jaw 8 of the prestressed disk springs 30 via the screw connection 24, 25 between the actuating shaft 12 and the jaw 9 has a tensile force, for example exceeding 1000 N, on the jaw 9, which between the two jaws 8 and 9 on the one hand, which are defined in their axial position on the one hand, and the ring 14 which is firmly connected to the handwheel 3 on the other hand provides a firm frictional engagement or positive fit causes, whereby the handwheel 3 is locked in its desired position and fixed. The play in the locking device is assumed, for example, in the size of 0.1 mm. The transmission of this game to the handwheel of the shooting device under discussion then corresponds to an angle of approximately 0.1 ° (degrees), which angular play is reduced to approximately 2.3 "(seconds) by the translation to the height coordinate (according to this example from 1: 140) , which is also negligible for precise position measurements.

Insbesondere ist die gezeigte Lösung für eine Arretiervorrichtung vielen Applikationen zugänglich, insbesondere bei der Verwendung der elektrischen Betätigung. So kann zum Beispiel irgend eine Welle in einem Mechanismus (bspw. Getriebe) gezielt auf die beschriebene Weise fixiert werden, um direkt eine nahezu spielfreie Arretierung und über einen evtl. übersetzten Wirkungspfad eine Arretierung mit vernachlässigbarem Spiel (spielfrei) herbeizuführen. Zudem ist die Arretiereinrichtung wartungsfrei und in hohen Masse betriebssicher, sodass sie sich auch dort zum Einsatz anbietet, wo, aus Gründen der Sicherheit solche Fixiermechanismen mit viel Aufwand an frei zugänglichen Stellen einer Vorrichtung angeordneten werden mussten.In particular, the solution shown for a locking device is accessible to many applications, in particular when using the electrical actuation. For example, any shaft in a mechanism (e.g. gearbox) can be specifically fixed in the manner described in order to directly lock it with almost no play and via a possibly translated we path with a negligible play (play-free). In addition, the locking device is maintenance-free and highly reliable, so that it can also be used where, for reasons of safety, such fixing mechanisms had to be arranged with a lot of effort at freely accessible locations on a device.
