Description

TOURBILLONTOURBILLON
Die Erfindung betrifft ein TourbiUon, respektive ein Tourbillonmodul, gemäss dem Oberbegriff des unabhängigen Patentanspruchs.The invention relates to a TourbiUon, or a tourbillon module, according to the preamble of the independent claim.
Aus dem Stand der Technik sind Uhrwerke mit einem TourbiUon bekannt, die in der Regel kompliziert aufgebaut sind. Dadurch entstehen Nachteile bei der Herstellung und der Wartung. Ausserdem besteht keine Möglichkeit einen TourbiUon mit einem besonders flachen Aufbau zu erzielen.Movements with a TourbiUon are known from the prior art, which are generally of complex construction. This creates disadvantages in production and maintenance. In addition, there is no way to achieve a TourbiUon with a particularly flat structure.
Aus EP 0 681 227 ist ein zentrisch angeordneter TourbiUon bekannt, der vor einem Federhaus montiert ist. Dieser Aufbau ist hinsichtlich Montage und Unterhalt sehr aufwendig und daher teuer. Insbesondere bei einem Defekt ist es erforderlich das ganze Uhrwerk zu demontieren, um Zugang zum TourbiUon zu erhalten. Der TourbiUon ist zudem nur von vorne sichtbar.From EP 0 681 227 a centrally arranged TourbiUon is known, which is mounted in front of a barrel. This structure is very complex in terms of assembly and maintenance and therefore expensive. In the event of a defect in particular, it is necessary to dismantle the entire movement in order to gain access to the TourbiUon. The TourbiUon is also only visible from the front.
Die Firma IWC, Schaffhausen, baut seit 1993 einen fliegenden TourbiUon mit einer einseitigen Kugellagerung in das Modell „II Destriera Scafusia" ein. Dieser weist eine drehende Basis auf, die mit dem Aussenring des Lagers verbunden ist. Der Innenring des Lagers ist feststehend. Ein signifikanter Nachteil dieser Konstruktion besteht darin, dass sie keinen TourbiUon niedriger Bauhöhe zulässt. Ein weiterer Nachteil besteht darin, dass der TourbiUon, insbesondere dessen Lager, im eingebauten Zustand nicht von aussen zugänglich sind. Damit der TourbiUon, respektive dessen Lager zugänglich sind, muss das gesamte Uhrwerk zerlegt werden.IWC, Schaffhausen, has been installing a flying TourbiUon with one-sided ball bearings in the "II Destriera Scafusia" model since 1993. This has a rotating base that is connected to the outer ring of the bearing. The inner ring of the bearing is fixed A significant disadvantage of this construction is that it does not permit a TourbiUon of low overall height. Another disadvantage is that the TourbiUon, in particular its bearing, cannot be accessed from the outside when installed. In order for the TourbiUon or its bearing to be accessible, this must be possible entire movement can be disassembled.
Die Aufgabe der hier offenbarten Erfindung besteht darin, einen TourbiUon, respektive ein Tourbillonmodul mit einem wartungsfreundlichen, einfachen Aufbau und einer verbesserten Ganggenauigkeit zu zeigen, der bei Bedarf eine besonders niedere Bauhöhe des Tourbillons aufweist.The object of the invention disclosed here is to show a TourbiUon, or a tourbillon module with a maintenance-friendly, simple structure and improved accuracy, which if necessary has a particularly low overall height of the tourbillon.
Der erfindungsgemässe TourbiUon weist vorzugsweise einen modularen Aufbau auf. Der eigentliche Tourbillonmechanismus, inklusive aller wesentlichen Teile, sind vorzugsweise in einem Tourbillonmodul zusammengefasst, das eine normierte Schnittstelle zum Rest des Uhrwerks aufweist und auf einfache Art und Weise von diesem gelöst werden kann. Der TourbiUon weist bevorzugt eine Plattform auf, die einseitig gelagert ist (fliegender TourbiUon). Für die Lagerung wird bevorzugt ein Kugellager (Hauptlager) verwendet, wobei der Aussenring dieses Kugellagers mit der Plattform des Tourbillons mitrotiert. Die Plattform und der Aussenring können bei Bedarf einteilig ausgebildet sein. Infolge der gewählten Konstruktion besteht die Möglichkeit die Kugeln des Kugellagers im wesentlichen auf der Höhe der Plattform anzuordnen. Dies hat einen positiven Einfluss auf die Bauhöhe. Der Innenring des zentralen Lagers der Plattform ist fest an einer Basis angeordnet und rotiert nicht. Damit das Lagerspiel einfach eingestellt werden kann, besteht die Möglichkeit den Innen- und/oder der Aussenring zweiteilig auszugestalten. Eine Unruh ist mittels einem oberen und einem unteren Unruhlager gelagert. Bei gewissen Ausführungsformen rotieren beide Unruhlager mit der Plattform mit. Alternativ besteht die Möglichkeit das untere Unruhlager feststehend auf der Seite der Basis anzuordnen. Dies wirkt sich je nach Bauform vorteilhaft auf die Bauhöhe aus.The TourbiUon according to the invention preferably has a modular structure. The actual tourbillon mechanism, including all essential parts, are preferably combined in a tourbillon module, which has a standardized interface to the rest of the movement and can be detached from it in a simple manner. The TourbiUon preferably has a platform that is supported on one side (flying TourbiUon). A ball bearing (main bearing) is preferably used for the storage, the outer ring of this ball bearing also rotating with the platform of the tourbillon. The platform and the outer ring can be formed in one piece if necessary. As a result of the design chosen, it is possible to arrange the balls of the ball bearing essentially at the level of the platform. This has a positive impact on the overall height. The inner ring of the central bearing of the platform is fixed to a base and does not rotate. So that the bearing play can be easily adjusted, it is possible to design the inner and / or the outer ring in two parts. A balance is supported by an upper and a lower balance bearing. In certain embodiments, both balance bearings rotate with the platform. Alternatively, there is the option of arranging the lower balance bearing fixed on the side of the base. Depending on the design, this has an advantageous effect on the overall height.
Die aus dem Stand der Technik bekannten Tourbillonkonstruktionen weisen in der Regel den Nachteil auf, dass ein Justieren und Warten des Tourbillons, respektive der Lager des Tourbillons, im eingebauten Zustand nicht möglich ist. Falls ein TourbiUon gewartet werden soll, muss in der Regel das gesamte Uhrwerk zerlegt werden. Der hier offenbarte TourbiUon weist einen Aufbau auf, der eine einfache Wartung ermöglicht. Die Lager sind bevorzugt so angeordnet, dass sie auch in eingebauten Zustand einfach kontrolliert, justiert und gewartet werden können. Damit sowohl ein unteres Lager der Unruh (Unruhlager) als auch das Hauptlager der Plattform des Tourbillons frei zugärfglich sind, weist der Innenring des Hauptlagers der Plattform bevorzugt einen Durchmesser auf, der so gross ist, dass das untere Lager der Unruh (Unruhlager) in seiner Mitte Platz findet und bei Bedarf, insbesondere für Wartungszwecke, zugänglich ist. Durch eine koaxiale Anordnung wird erreicht, dass Kräfte infolge von äusseren Stössen und Schlägen besonders effizient abgeleitet werden. Ein weiterer Vorteil besteht darin, dass die Unruhlager bei einer koaxialen Anordnung weit auseinander angeordnet werden können, so dass die Unruhachse eine vergleichsweise maximale Länge aufweist, wodurch die Reaktionskräfte infolge von auftretenden Momenten, vergleichsweise minimiert werden. Zudem weisen Fabrikationstoleranzen in der Regel einen geringeren Einfluss auf.The tourbillon constructions known from the prior art generally have the disadvantage that it is not possible to adjust and maintain the tourbillon or the bearings of the tourbillon in the installed state. If a TourbiUon is to be serviced, the entire movement must usually be dismantled. The TourbiUon disclosed here has a structure that enables easy maintenance. The bearings are preferably arranged so that they can be easily checked, adjusted and serviced even when installed. So that both a lower bearing of the balance (balance bearing) and the main bearing of the platform of the tourbillon are freely accessible, the inner ring of the main bearing of the platform preferably has a diameter that is so large that the lower bearing of the balance (balance bearing) in it Mitte finds space and is accessible when needed, especially for maintenance purposes. A coaxial arrangement ensures that forces due to external shocks and impacts are dissipated particularly efficiently. A further advantage is that the balance bearings can be arranged far apart in a coaxial arrangement, so that the balance axis has a comparatively maximum length, whereby the reaction forces due to occurring moments are comparatively minimized. In addition, manufacturing tolerances generally have less influence.
Insbesondere aufgrund der Lagerung der Plattform des Tourbillons, ermöglicht die Erfindung sehr flache Tourbillons zu bauen, deren Höhe unter 5 mm und, falls erforderlich, unter 4 mm zu liegen kommt. Dies wird unter anderem dadurch erreicht, dass bei den sehr flachen Ausführungsformen die Mittel zur Lagerung der Tourbillonplattform (bei einem Kugellager die Kugeln) bevorzugt in etwa auf der Höhe der Hauptebene der Tourbillonplattform angeordnet sind. Die Tourbillonplattform weist zu diesem Zweck eine entsprechend grosse Öffnung auf. Bei diesen Ausführungsformen wird der Aussenring des Hauptlagers der Plattform bevorzugt in die Plattform integriert. Eine kinematische Umkehr der Lageiteile des Hauptlagers ist bei gewissen Ausführungsformen möglich. Dabei kommen die Mittel zur Lagerung der Tourbillonplattform in etwa auf die Höhe der Basis zu liegen, wobei der Aussenring des Hauptlagers feststehend und der Innenring rotierend angeordnet ist.In particular due to the mounting of the tourbillon platform, the invention enables very flat tourbillons to be built, the height of which is less than 5 mm and, if necessary, less than 4 mm. This is achieved, inter alia, in that, in the very flat embodiments, the means for mounting the tourbillon platform (for a ball bearing, the balls) are preferably arranged approximately at the level of the main level of the tourbillon platform. The tourbillon platform assigns a correspondingly large opening for this purpose. In these embodiments, the outer ring of the main bearing of the platform is preferably integrated into the platform. A kinematic reversal of the position parts of the main bearing is possible in certain embodiments. The means for mounting the tourbillon platform come to lie approximately at the level of the base, the outer ring of the main bearing being stationary and the inner ring being arranged in a rotating manner.
Insbesondere bei Ausführungsformen, bei denen die Kugeln des Hauptlagers in etwa auf der Höhe der Plattform, respektive der Basis angeordnet sind, ist es sinnvoll das untere Lager der Unruh im Innern des Hauptlagers koaxial, auf der feststehenden Seite (uhrwerksseitig) anzuordnen. Dadurch wird die Bauhöhe bei Bedarf zusätzlich reduziert.In particular in embodiments in which the balls of the main bearing are arranged approximately at the level of the platform or the base, it makes sense to arrange the lower bearing of the balance inside the main bearing coaxially on the fixed side (clockwork side). This further reduces the overall height if necessary.
Das untere Lager der Unruh und das Hauptlager der Plattform des Tourbillons sind bevorzugt im Wesentlichen koaxial angeordnet, da dadurch mechanische Stösse und Schwingungen besonders gut abgeleitet werden.The lower bearing of the balance wheel and the main bearing of the platform of the tourbillon are preferably arranged essentially coaxially, since mechanical shocks and vibrations are thereby particularly well dissipated.
Anstelle eines integrierten Hauptlagers kann auch ein Industrielager verwendet werden. Dadurch nimmt jedoch die Anzahl Teile zu und das Lagerspiel kann, je nach Ausführungsform, nicht optimal eingestellt werden. Fertige Lager werden bevorzugt durch Einpressen oder Kleben befestigt.Instead of an integrated main warehouse, an industrial warehouse can also be used. However, this increases the number of parts and, depending on the embodiment, the bearing play cannot be optimally adjusted. Finished bearings are preferably attached by pressing or gluing.

Der TourbiUon 1 ist als Tourbillonmodul 1 konzipiert, das unabhängig vom Rest des Uhrwerks gefertigt und anschliessend montiert wird. Das Tourbillonmodul 1 weist eine Plattform 2 auf, die auf einer Basis 3 um eine Drehachse A drehbar gelagert ist. Die Plattform 2 weist eine Aussenver- zahnung 8 auf, über welche das Tourbillonmodul 1 angetrieben, respektive das Uhrwerk gehemmt wird. Auf der Plattform 2 ist zentrisch eine Unruh 9 drehbar angeordnet, die mit dem Inneren Ende einer Spiralfeder 10 wirkverbunden ist. Die Unruh 9 wird über ein Ankerrad 1 1 und ein Anker 12 (nur teilweise ersichtlich) angetrieben, respektive gehemmt. Auf der Plattform 2 sind drei Stützen 15 angeordnet, die eine Brücke 16 halten. In der Mitte der Brücke 16 ist koaxial zur Drehachse A ein oberes Unruhlager 18 angeordnet. Ein Regelmechanismus 17 steht mit einem äusseren Bereich 4 der Spiralfeder 10 in Wirkverbindung. Der Regelmechanismus 17 dient zur Feineinstellung der Ganggenauigkeit des Tourbillonmoduls 1 , indem er auf die wirksame Länge der Spiralfeder 10 Einfluss nimmt. Ein äusseres Ende 5 der Spiralfeder 10 ist über eine Halterung 6 an der Brücke 16 befestigt. Die Basis 3 weist Öffnungen 7 (Befestigungsmittel) auf, die zur Befestigung der Basis 3 an einer Platine eines Uhrwerks (nicht näher dargestellt) dienen.

The design of the Tourbillon 1 is a flying TourbiUon that is one-sided is stored. The TourbiUon 1 is designed as a tourbillon module 1, which is manufactured independently of the rest of the movement and then assembled. The tourbillon module 1 has a platform 2 which is mounted on a base 3 so as to be rotatable about an axis of rotation A. The platform 2 has an external toothing 8, via which the tourbillon module 1 is driven or the clockwork is inhibited. A balance 9 is rotatably arranged centrally on the platform 2 and is operatively connected to the inner end of a spiral spring 10. The balance wheel 9 is driven or inhibited via an escape wheel 11 and an anchor 12 (only partially visible). On the platform 2, three supports 15 are arranged which hold a bridge 16. In the middle of the bridge 16, an upper balance bearing 18 is arranged coaxially to the axis of rotation A. A control mechanism 17 is operatively connected to an outer region 4 of the spiral spring 10. The control mechanism 17 serves to fine-tune the accuracy of the tourbillon module 1 by influencing the effective length of the coil spring 10. An outer end 5 of the spiral spring 10 is fastened to the bridge 16 via a holder 6. The base 3 has openings 7 (fastening means) which are used to fasten the base 3 to a circuit board of a clockwork (not shown in more detail). Figure 2 shows a sectional view along the line DD.

Ein Aussenring 21 des Hauptlagers 20 ist starr mit der Plattform 2 verbunden und dreht mit dieser mit. Der Aussenring 21 weist eine glockenförmige Ausgestaltung mit einer durchgehenden Öffnung mit einem veränderlichen Innendurchmesser mit zwei ausgeprägten Durchmesserniveaus aus. Der Aussenring 24 ist bei der gezeigten Ausführungsform, über einen Presssitz mit der Plattform 2 verbunden. Der Aussenring 24 ist so ausgestaltet, dass er als Halterung eines unteren Unruhlagers 19 dient. Das untere Unruhlager 19 ist auf der Seite der Plattform 2 angeordnet und rotiert mit dieser mit. Ein Vorteil besteht darin, dass die auf der Plattform 2 angeordneten Teile und Mittel, inkl. der Unruh 9, unabhängig von der Basis 3 aufgebaut werden können. Ein Innenring 22 ist zweiteilig ausgestaltet und besteht aus einem festen, ersten Teilring 23 und einem justierbaren, zweiten Teilring 24, der mit dem ersten Innenring 23 über ein Gewinde 25 derart wirkverbunden ist, dass das Lagerspiel einstellbar ist. Durch diese Anordnung ist es möglich das Hauptlager 20 zu montieren und das Lagerspiel einzustellen. Alternative Ausführungsformen, zum Beispiel mit einem Presssitz, sind möglich. Die Unruh 9 ist auf einer Unruhachse 13 befestigt, die wiederum mittels einem ersten, unteren und einem zweiten, oberen schock- und vibrationsabsorbierenden Gleitlager 18, 19 (Unruhlager) um die Drehachse A drehbar gelagert ist. Das untere Gleitlager 19 ist hier leicht oberhalb des Hauptlagers 20 angeordnet. Bei anderen Ausführungsformen können das Hauptlager 20 und das untere Gleitlager 19 im Wesentlichen auf derselben Höhe angeordnet sein. Ein bei der gezeigten Ausführungsform innenverzahntes Zahnrad 26 ist mit der Basis 3 wirkverbunden und bezüglich der Drehachse A zentriert. Das innenverzahnte Zahnrad 26 dient zum Antrieb des Ankerrades 1 1 über ein Ritzel 27 (vgl. Figur 4). Die Basis 3 und das Zahnrad 26 können bei Bedarf einteilig ausgebildet sein.FIG. 2 shows a section along the line DD through the tourbillon module 1 from FIG. 1. A main bearing 20 serves to support the platform 2 of the tourbillon 1 relative to the base 3. An outer ring 21 of the main bearing 20 is rigidly connected to the platform 2 and rotates with it this one with. The outer ring 21 has a bell-shaped configuration with a continuous opening with a variable inner diameter with two pronounced diameter levels. In the embodiment shown, the outer ring 24 is connected to the platform 2 via a press fit. The outer ring 24 is designed such that it serves as a holder for a lower balance bearing 19. The lower balance bearing 19 is arranged on the side of the platform 2 and rotates with it. One advantage is that the parts and means, including the balance 9, arranged on the platform 2 can be constructed independently of the base 3. An inner ring 22 is configured in two parts and consists of a fixed, first partial ring 23 and an adjustable, second partial ring 24, which is operatively connected to the first inner ring 23 via a thread 25 such that the bearing play is adjustable. This arrangement makes it possible to mount the main bearing 20 and to adjust the bearing play. Alternative embodiments, for example with a press fit, are possible. The balance 9 is fastened on a balance axis 13, which in turn is mounted rotatably about the axis of rotation A by means of a first, lower and a second, upper shock and vibration absorbing slide bearing 18, 19 (balance bearing). The lower slide bearing 19 is arranged slightly above the main bearing 20 here. In other embodiments, the main bearing 20 and the lower slide bearing 19 can be arranged at substantially the same height. A gearwheel 26 with internal teeth in the embodiment shown is operatively connected to the base 3 and centered with respect to the axis of rotation A. The internally toothed gear 26 serves to drive the escape wheel 11 via a pinion 27 (cf. FIG. 4). The base 3 and the gear 26 can be formed in one piece if necessary.
Figur 3 zeigt eine weitere Ausführungsform eines Tourbillonmoduls 1 in einer perspektivischen Darstellung von schräg oben. Obschon dieses Tourbillonmodul 1 von vorne im Wesentlichen der Ausführungsform aus Figur 1 entspricht, unterscheidet es sich wesentlich im Aufbau des Hauptlagers. Die hier gezeigte Ausführungsform ist so konzipiert, dass sie von hinten auf einer Platine eines Uhrwerk befestigt werden kann, wobei der TourbiUon 1 in einer geeigneten, durchgehenden Öffnung der Platine angeordnet von vorne (Zifferblattseitig) sichtbar ist. Das innenverzahnte Zahnrad 26 ist konzentrisch zur Drehachse A angeordnet und mittels zwei Schrauben 29 an der Basis 3 befestigt. Andere Befestigungsmöglichkeiten, z.B. von vorne, sind möglich. Die Nummerierung entspricht den Figuren 1 und 2.Figure 3 shows a further embodiment of a tourbillon module 1 in a perspective view obliquely from above. Although this tourbillon module 1 essentially corresponds to the embodiment from FIG. 1 from the front, it differs significantly in the structure of the main bearing. The embodiment shown here is designed so that it can be fastened from behind on a circuit board of a clockwork, the TourbiUon 1 being arranged in a suitable, continuous opening in the circuit board and visible from the front (dial side). The internally toothed gear 26 is arranged concentrically to the axis of rotation A and fastened to the base 3 by means of two screws 29. Other mounting options, e.g. from the front, are possible. The numbering corresponds to Figures 1 and 2.
Figur 4 zeigt das Tourbillonmodul 1 gemäss Figur 3 in einer perspektivischen Ansicht von schräg unten. Die Basis 3 weist hier eine Lageröffnung 28 auf in welcher der zweite Teilring 24 des Hauptlagers 20 zu erkennen ist. In der Mitte des zweiten Teilringes 24 ist das untere Gleitlager 19 der Unruh 9, respektive der Unruhachse 13 (vgl. Figur 5) zu erkennen. Anstelle des innenverzahnten Zahnrades 26 kann auch ein aussenverzahntes Zahnrad (nicht dargestellt) verwendet werden. Das Zahnrad 26 kann bei Bedarf in die Plattform 3 integriert sein. Bei gewissen Ausführungsformen besteht die Möglichkeit das Hauptlager 20 kinematisch umzukehren, indem der Innenring 24 des Hauptlagers rotierend und der Aussenring 21 mit der Basis 3 verbunden feststehend angeordnet sind. Dadurch wird jedoch die Dicke der Basis 3 tendenziell vergrössert, was sich auf die Bauhöhe des Tourbillons 1 auswirken kann. Bei der gezeigten Ausführungsform besteht die Möglichkeit, die Basis 3 sehr dünn auszugestalten. Die Dicke t wird ist im Wesentlichen nur durch die für einen Betrieb erforderlichen mechanische Festigkeit, respektive Herstellbarkeit gegeben ist. Dies wirkt sich positiv auf eine geringe Bauhöhe aus.FIG. 4 shows the tourbillon module 1 according to FIG. 3 in a perspective view obliquely from below. The base 3 here has a bearing opening 28 in which the second partial ring 24 of the main bearing 20 can be seen. In the middle of the second partial ring 24, the lower slide bearing 19 of the balance 9, or the balance axis 13 (see FIG. 5) can be seen. Instead of the internally toothed gear 26, an externally toothed gear (not shown) can also be used. The gear 26 can be integrated into the platform 3 if necessary. In certain embodiments, there is the possibility of kinematically reversing the main bearing 20 in that the inner ring 24 of the main bearing rotates and the outer ring 21 is fixedly connected to the base 3. However, this tends to increase the thickness of the base 3, which can affect the overall height of the tourbillon 1. In the embodiment shown, it is possible to make the base 3 very thin. The thickness t is essentially given only by the mechanical strength or manufacturability required for operation. This has a positive effect on a low overall height.
Figur 5 zeigt die Ausführungsform des Tourbillons 1 gemäss den Figuren 3 und 4 in einer perspektivischen Schnittdarstellung. Das Hauptlager 20 und das untere Unruhlager 19 der Unruh 9, respektive der Unruhachse 13 befinden sich hier im Wesentlichen auf derselben Höhe in einer koaxialen Anord- nung. Das untere Unruhlager 19 ist mit der Basis 3 wirkverbunden und dreht daher nicht mit der Plattform 2 mit. Bei dieser Ausführungsform ist der Aussenring 21 des Hauptlagers 20 in die Plattform 2 integriert. Dies bietet den Vorteil, dass die Anzahl der erforderlichen und aufeinander abzustimmenden Teile verringert wird. Diese Ausführungsform eignet sich für Tourbillons geringer Bauhöhe, die in flachen Kalibern oder von vorne montiert zum Einsatz kommen. Zwischen dem Aussen- und dem Innenring 21 , 22 des Hauptlagers 20 sind Kugeln 28 zu erkennen. Durch den justierbaren Aufbau des Hauptlagers 20, mittels einem ersten und einem zweiten Teilring 23, 24, die über ein Gewinde 25 justierbar wirkverbunden sind, wird das Lagerspiel des Hauptlagers 20 eingestellt.Figure 5 shows the embodiment of the tourbillon 1 according to Figures 3 and 4 in a perspective sectional view. The main bearing 20 and the lower balance bearing 19 of the balance 9 and the balance axis 13 are located essentially at the same height in a coaxial arrangement. voltage. The lower balance bearing 19 is operatively connected to the base 3 and therefore does not rotate with the platform 2. In this embodiment, the outer ring 21 of the main bearing 20 is integrated in the platform 2. This has the advantage that the number of required and coordinated parts is reduced. This embodiment is suitable for tourbillons of low overall height, which are used in flat calibres or mounted from the front. Balls 28 can be seen between the outer and inner rings 21, 22 of the main bearing 20. Due to the adjustable structure of the main bearing 20, by means of a first and a second partial ring 23, 24, which are adjustably operatively connected via a thread 25, the bearing play of the main bearing 20 is set.
Die Achse 13 der Unruh 9 ist in einem oberen Unruhlager 18 und in einem unteren Unruhlager 19 gelagert. Bei den Unruhlagern 18, 19 handelt es sich um schock- und vibrationsabsorbierende Gleitlager. Das obere Unruhlager 18 ist an einer Brücke 16 befestigt, die wiederum mittels Schrauben 14 auf stützen 15 befestigt ist. Die Stützen 1 5 sind auf der Plattform 2 befestigt. Bei der gezeigten Ausführungsform handelt es sich um Pressverbindungen. Alternativ kann eine andere Verbindungsform gewählt werden. Das untere Unruhlager 19 ist feststehend, daher ausserhalb der drehbar angeordneten Plattform 2, angebracht. Bei der gezeigten Ausführungsform ist das untere Unruhlager mit dem ersten Teilring 23 des Innenringes 22 des Hauptlagers 20 wirkverbunden. Eine alternative Ausführungsform besteht darin, das untere Unruhlager 19 ausserhalb des Hauptlagers 20 anzuordnen.The axis 13 of the balance 9 is mounted in an upper balance bearing 18 and in a lower balance bearing 19. The balance bearings 18, 19 are shock and vibration absorbing plain bearings. The upper balance bearing 18 is fastened to a bridge 16, which in turn is fastened to supports 15 by means of screws 14. The supports 1 5 are attached to the platform 2. The embodiment shown is a press connection. Alternatively, another form of connection can be selected. The lower balance bearing 19 is fixed, therefore outside of the rotatably arranged platform 2. In the embodiment shown, the lower balance bearing is operatively connected to the first partial ring 23 of the inner ring 22 of the main bearing 20. An alternative embodiment consists in arranging the lower balance bearing 19 outside the main bearing 20.
Die auf der Unruhachse 13 drehbar gelagerte Unruh 9 ist über einen zur Achse A parallel angeordneten Unruhzapfen 29 mit dem Anker 12 wirkverbunden. Der Anker 12 ist auf einer Ankerachse 30, die mittels zwei Ankerlagern 31 (wovon hier nur das obere sichtbar ist) gegenüber der Plattform 2 gelagert ist, angeordnet. Die Ankerwelle 30 ist bei der gezeigten Ausführungsform um eine zweite Drehachse B drehbar angeordnet. Die zweite Drehachse B ist parallel zur Hauptdrehachse A angeordnet.The balance 9, which is rotatably mounted on the balance axis 13, is operatively connected to the armature 12 via a balance pin 29 arranged parallel to the axis A. The anchor 12 is arranged on an anchor axis 30, which is mounted opposite the platform 2 by means of two anchor bearings 31 (only the upper one of which is visible here). The armature shaft 30 is arranged rotatable about a second axis of rotation B in the embodiment shown. The second axis of rotation B is arranged parallel to the main axis of rotation A.
Der Anker 12 steht in Wirkverbindung mit dem Ankerrad 1 1 , das auf einer Ankerradwelle 32 mit einem Ritzel 27 befestigt ist. Die Ankerradwelle 32 ist um eine zweite Drehachse C mittels zwei an der Plattform 2 befestigten Ankerradlagem 33 drehbar gelagert. Das Ritzel 27 steht wiederum in Eingriff mit dem hier innenverzahnten, auf der Basis 3 befestigten Zahnrad 26. Der Hemmmechanismus 34, der das Ankerrad 1 1 , den Anker 12 und den Unruhzapfen 29, sowie die zwischen diesen wirkenden Wirkverbindungen umfasst, dient zum Antrieb, respektive zur Hemmung der Unruh 9. Um die Bauhöhe des Tourbillons 1 zu minimieren, besteht bei gewissen Ausführungsformen die Möglichkeit die Kugeln 28 des Hauptlagers 20 in etwa auf der Höhe der Plattform 2 anzuordnen. Bei gewissen Ausführungsformen ist es sinnvoll den Hemmmechanismus 34, sowie das Ritzel 27 und das Zahnrad 26 oberhalb der Unruh 9 anzuordnen. Der zweite Teilring 24 kann bei einer entsprechenden Formgebung und Anordnung des Hauptlagers 20 so ausgestaltet sein, dass er auf einem Aussenbe- reich eine Verzahnung (nicht näher dargestellt) aufweist oder mit dieser Wirkverbunden ist. Diese Verzahnung kämmt mit dem Ritzel 27 und dient als Ersatz für das Zahnrad 26. Dadurch besteht die Möglichkeit die Anzahl Teile, sowie die Bauhöhe weiter zu reduzieren. Bei einer solchen Anordnung ist das Ankerrad 1 1 in der Regel zwischen der Unruh 9 und der Plattform 2 und das Ritzel 27 zwischen der Unruh, respektive dem Ankerrad 1 1 und der Plattform 2 angeordnet.The armature 12 is operatively connected to the armature wheel 1 1, which is fastened on an armature wheel shaft 32 with a pinion 27. The escape wheel shaft 32 is rotatably supported about a second axis of rotation C by means of two escape wheel bearings 33 attached to the platform 2. The pinion 27 is in turn in engagement with the gearwheel 26, which is internally toothed here and fastened on the base 3. respectively to inhibit the balance 9. In order to minimize the overall height of the tourbillon 1, it is possible in certain embodiments to arrange the balls 28 of the main bearing 20 approximately at the height of the platform 2. In certain embodiments, it is useful to arrange the locking mechanism 34, as well as the pinion 27 and the gear 26 above the balance 9. With a corresponding shape and arrangement of the main bearing 20, the second partial ring 24 can be designed such that it has teeth (not shown in more detail) on an outer area or is operatively connected to it. This toothing meshes with the pinion 27 and serves as a replacement for the gearwheel 26. This makes it possible to further reduce the number of parts and the overall height. With such an arrangement, the escape wheel 11 is generally arranged between the balance 9 and the platform 2 and the pinion 27 between the balance, respectively the escape wheel 11 and the platform 2.
Die erfindungsgemässe Konstruktion des Tourbillons 1 bietet den Vorteil, dass insbesondere die Lager der Unruh 18, 19 im eingebauten Zustand zugänglich sind und gewartet werden können, ohne dass der TourbiUon 1 , respektive das Tourbillonmodul aus einem Uhrwerk ausgebaut oder komplett auseinander genommen werden muss.The construction of the tourbillon 1 according to the invention offers the advantage that, in particular, the bearings of the balance 18, 19 are accessible and can be serviced in the installed state without the tourbillon 1 or the tourbillon module having to be removed from a clockwork or completely disassembled.
Anstelle eines integrierten Hauptlagers 20 kann auch ein separat gefertigtes, standardisiertes Kugellager verwendet werden, das durch Einpressen, Kleben oder auf eine andere Art und Weise befestigt wird. Vorzugsweise befinden sich die Kugeln des Lagers in etwa auf der Höhe der Plattform 3, da so eine besonders geringe Bauhöhe erzielt werden kann. Instead of an integrated main bearing 20, a separately manufactured, standardized ball bearing can also be used, which is attached by pressing, gluing or in some other way. The balls of the bearing are preferably approximately at the level of the platform 3, since a particularly low overall height can be achieved in this way.
