Description

Die vorliegende Erfindung betrifft ein Hemmungssystem, welches beispielsweise in einem Messgerät, wie z.B. einer Uhr, verwendet werden kann. Das Hemmungssystem umfasst eine Antriebsachse und mindestens ein Hemmungsrad, welches mehrere Impulszähne aufweist. Jeder der Impulszähne mit der Antriebsachse über jeweils ein Federelement verbunden und besitzt eine Ausgangsposition, in der er so fixiert ist, dass das Federelement ein Vorspannmoment aufweist.The present invention relates to an escapement system which can be used, for example, in a measuring device such as a watch. The escapement system includes a drive axle and at least one escapement wheel having a plurality of pulse teeth. Each of the impulse teeth is connected to the drive shaft via a respective spring element and has an initial position in which it is fixed such that the spring element has a preload torque.

Es ist bekannt, dass Gangregler in Ablaufgetrieben und Uhren diversen Kraftschwankungen unterliegen, die ihre Ursachen unter anderem in der Qualität der Antriebsfeder, des Ablaufgetriebes oder der Schmiermittel haben. Diese Kraftschwankungen beeinflussen ursächlich den Isochronismus des Gangreglers und damit die Qualität einer Uhr. Deshalb ist man bemüht den sich während des Impulses bewegenden Antriebsstrang möglichst kurz zu halten um die Anzahl der Störquellen zu minimieren. Zur Lösung dieser Problematik ist aus der CH 708 043 bekannt, die Zähne des Hemmungsrades auf federnde Elemente zu setzen, die durch die Kraft, die durch den Kraftstrang an das Hemmungsrad übertragen wird, auf ein Energieniveau angehoben werden. Die so gespeicherte Energie wird während der Impulsübertragung teilweise an die Hebeflächen des Ankers abgegeben. Zu dieser Energie kommt aber stets auch die durch die Rotation des Hemmungsrades übertragene Energie hinzu, die bekanntermassen starken Schwankungen unterliegt, so dass die in der CH 708 043 beschriebene Vorrichtung die Schwankungen zwar etwas abschwächt, aber nicht beseitigen kann, wie im dort zitierten Text auch richtig dargelegt wird. Eine durchaus vergleichbare Vorrichtung zeigt die US 2717488 , bei der jedoch die Geräuschminimierung einer Hemmung im Fokus steht.It is well known that rate regulators in drain gears and watches are subject to various force fluctuations, which are caused, among other things, by the quality of the drive spring, the drain gear or the lubricant. These power fluctuations have a causal effect on the isochronism of the rate regulator and thus on the quality of a watch. Efforts are therefore made to keep the drive train moving during the impulse as short as possible in order to minimize the number of sources of interference. To solve this problem is from the CH 708 043 It is known to place the teeth of the escape wheel on resilient members which are raised to an energy level by the force transmitted through the power train to the escape wheel. The energy thus stored is partially released to the lifting surfaces of the armature during momentum transfer. In addition to this energy, however, there is always the energy transmitted by the rotation of the escapement wheel, which is known to be subject to strong fluctuations, so that the CH 708 043 The device described reduces the fluctuations somewhat, but cannot eliminate them, as is also correctly explained in the text cited there. A quite comparable device shows the US2717488 , but where the focus is on minimizing the noise of an escapement.

Der vorliegenden Erfindung liegt jedoch eine andere Aufgabenstellung zu Grunde. So war es die Aufgabe der vorliegenden Erfindung ein Hemmungssystem mit konstanter Impulsenergie und hohem Wirkungsgrad anzugeben. Diese Aufgabe wird bezüglich eines Hemmungssystems mit den Merkmalen des Patentanspruchs 1 und bezüglich eines Messgeräts mit den Merkmalen des Patentanspruchs 11 gelöst. Die jeweilig abhängigen Patentansprüche stellen dabei vorteilhafte Weiterbildungen dar.However, the present invention is based on a different task. It was therefore the object of the present invention to specify an escapement system with constant pulse energy and high efficiency. This object is achieved with the features of patent claim 1 with regard to an escapement system and with the features of patent claim 11 with regard to a measuring device. The respective dependent patent claims represent advantageous developments.

Erfindungsgemäß wird somit ein Hemmungssystem angegeben, welches eine Antriebsachse und mindestens ein Hemmungsrad umfasst, wobei das mindestens eine Hemmungsrad mehrere Impulszähne aufweist. Jeder der Impulszähne ist mit der Antriebsachse über jeweils ein Federelement verbunden und besitzt eine Ausgangsposition (oder nimmt vorzugsweise eine Ausgangsposition ein), in der er so fixiert ist, dass das Federelement ein Vorspannmoment aufweist.According to the invention, an escapement system is thus specified which comprises a drive axle and at least one escapement wheel, the at least one escapement wheel having a plurality of impulse teeth. Each of the impulse teeth is connected to the drive axle via a respective spring element and has (or preferably assumes an initial position) an initial position in which it is fixed such that the spring element has a preload torque.

Der Impulszahn bzw. die Impulszähne des Hemmungsrads besitzen jeweils mindestens zwei Positionen, die sie einnehmen können. Eine dieser Positionen ist die Ausgangsposition, in welcher der Impulszahn ein niedriges Energieniveau aufweist und in welcher sich der Impulszahn befindet, solange er nicht auf sein hohes Energieniveau gehoben wird, dort gehalten wird oder er sich in der Phase der Energieübertragung befindet. Eine weitere Position ist z.B. die Spannposition, in welcher der Impulszahn sein hohes Energieniveau aufweist und in welche der Impulszahn während der Drehung des Hemmungsrads (Δα) gebracht wird, ehe er nach seiner Energieabgabe wieder in die Ausgangsposition zurückkehrt. Die Ausgangsposition kann hierbei auch als die Position bezeichnet werden, in der der Impulszahn bzw. das Federelement bei einem Zyklus des Hemmungsrads die geringste Spannung aufweist. Die Spannposition kann wiederum auch als die Position bezeichnet werden, in der der Impulszahn bzw. das Federelement bei einem Zyklus des Hemmungsrads die höchste Spannung aufweist. Die Spannung des Impulszahns bzw. des Federelements ist somit grundsätzlich in der Ausgangsposition niedriger als in der Spannposition.The impulse tooth or the impulse teeth of the escapement wheel each have at least two positions that they can occupy. One of these positions is the home position, in which the impulse tooth is at a low energy level, and in which the impulse tooth is unless it is raised to its high energy level, held there, or in the energy transfer phase. Another position is, for example, the clamping position, in which the impulse tooth has its high energy level and into which the pulse tooth is brought during the rotation of the escapement wheel (Δα) before returning to the starting position after releasing its energy. The starting position can also be referred to as the position in which the impulse tooth or the spring element has the lowest tension during one cycle of the escapement wheel. The tensioning position can in turn also be referred to as the position in which the impulse tooth or the spring element has the highest tension during one cycle of the escapement wheel. The tension of the impulse tooth or the spring element is therefore basically lower in the starting position than in the tensioned position.

Die vorliegende Erfindung zeichnet sich dadurch aus, dass der Impulszahn, während er sich in der Ausgangsposition befindet, ein Vorspannmoment (> 0 Nm) aufweist. Mit anderen Worten ist der Impulszahn in seiner Ausgangsposition bereits mit einem Moment vorgespannt.The present invention is characterized in that the impulse tooth has a preload torque (>0 Nm) while in the home position. In other words, the impulse tooth is already prestressed with a moment in its initial position.

Hierin unterscheidet sich die vorliegende Erfindung maßgeblich von den in der US 2717488 und der CH 708 043 beschriebenen Vorrichtungen. Dort werden ebenfalls federnde Impulszähne vorgeschlagen. In der US 2717488 werden diese jedoch zur Verminderung der Hemmungsgeräusche eingesetzt. Eine Vorspannung der federnden Impulszähne in der Ausgangsposition offenbart die US 2717488 nicht. Die CH 708 043 greift eine ähnliche technische Lösung auf, beabsichtigt jedoch eine Force-Constant Hemmung darzustellen, wobei die Impulszähne in ihrer Ausgangsposition bzw. Ruhelage keine Vorspannung aufweisen und das Hemmungsrad über keine gesonderten Ruhezähne verfügt.This is where the present invention differs significantly from those in FIG US2717488 and the CH 708 043 devices described. Springy impulse teeth are also proposed there. In the US2717488 however, these are used to reduce escapement noise. A bias of the resilient impulse teeth in the starting position reveals the US2717488 Not. the CH 708 043 takes up a similar technical solution, but intends to represent a force-constant escapement, whereby the impulse teeth have no pretension in their starting position or rest position and the escapement wheel has no separate rest teeth.

Dadurch, dass bei der vorliegenden Erfindung der mindestens eine Impulszahn in seiner Ausgangsposition ein Vorspannmoment aufweist, weist das erfindungsgemäße Hemmungssystem einen im Hemmungsrad integrierten Energiespeicher auf, der den Impuls direkt oder indirekt (z.B. über einen Anker) an eine Unruhe weitergeben kann. Dieser Energiespeicher ist hierbei in jeden einzelnen Impulszahn oder in jede Gruppe aus Impulszähnen des Hemmungsrades integriert.Due to the fact that in the present invention the at least one impulse tooth has a pretensioning moment in its starting position, the escapement system according to the invention has an energy store integrated in the escapement wheel, which can transmit the impulse directly or indirectly (e.g. via an anchor) to a balance wheel. This energy store is integrated in each individual pulse tooth or in each group of pulse teeth of the escapement wheel.

Bei der Hemmungsentwicklung stellt die Trägheit der impulsgebenden Elemente eine große Herausforderung dar. Sie bestimmt maßgeblich die Größe der Hemmungsräder und die Frequenz der Unruhe. Bei Schwingungen mit 2,5 Hz aufwärts werden typischerweise mehr als 60 % (meist mehr als 70 %) der Energie für die Beschleunigung der impulsgebenden Elemente verbraucht. Durch die vorliegende Erfindung wird die Trägheit des impulsgebenden Elementes minimiert, wodurch weniger Energie für die Beschleunigung der impulsgebenden Elemente verbraucht wird. Hierdurch kann die Effizienz des Hemmungssystems deutlich erhöht werden.When developing the escapement, the inertia of the stimulating elements poses a major challenge. It largely determines the size of the escapement wheels and the frequency of the balance wheel. For vibrations of 2.5 Hz and higher, typically more than 60% (usually more than 70%) of the energy is consumed in accelerating the stimulating elements. The present invention minimizes the inertia of the impeller, thereby expending less energy in accelerating the impeller. This can significantly increase the efficiency of the escapement system.

Der Wirkungsgrad des Hemmungssystems ergibt sich in grober Näherung aus der Formel: η = M H + M L / 2 − E 1 / Δ α / M A mit M A ≥ M H ,

Figure imgb0001
wobei η der Wirkungsgrad, ML das Vorspannmoment in der Ausgangsposition bzw. das niedrige Moment, MH das Moment in der Spannposition bzw. das hohe Moment, E1 die kinetische Energie der während des Impulses bewegten Hemmungsteile zu Impulsende, Δα den Drehwinkel des Hemmungsrades je Impuls und MA das Drehmoment des Hemmungsrads angibt. Für einen korrekten Ablauf ist es erforderlich, dass die Antriebsachse des Hemmungsrades ein höheres Drehmoment MA abgibt, als zum Spannen des Impulszahns erforderlich ist. Durch das erfindungsgemäß vorgesehene von 0 Nm verschiedene Vorspannmoment ML steigt die Effizienz der Hemmung maßgeblich, da mehr von der zum Spannen erforderlichen Energie (Δα · MA) gespeichert werden kann.The efficiency of the escapement system results in a rough approximation from the formula: n = M H + M L / 2 − E 1 / Δ a / M A With M A ≥ M H ,
Figure imgb0001
 where η is the efficiency, ML the pretensioning moment in the starting position or the low moment, MH the moment in the tensioning position or the high moment, E1 the kinetic energy of the escapement parts moving during the impulse at the end of the impulse, Δα the angle of rotation of the escapement wheel impulse and M A indicates the torque of the escape wheel. For a correct process, it is necessary that the drive axle of the escapement wheel delivers a higher torque M A than is required to tension the impulse tooth. As a result of the pretensioning torque M L different from 0 Nm provided according to the invention, the efficiency of the escapement increases significantly, since more of the energy (Δα · M A ) required for tensioning can be stored.

Minimale Trägheit und ein möglichst hohes Vorspannmoment ML des Impulszahns bzw. der Impulszähne in der Ausgangsposition tragen somit maßgeblich zur hohen Effizienz des erfindungsgemäßen Hemmungssystems bei, wohingegen ohne ein Vorspannen in der Ausgangsposition maximal 50 % der verfügbaren Energie genutzt werden können.Minimal inertia and the highest possible pretensioning moment M L of the impulse tooth or impulse teeth in the starting position thus contribute significantly to the high efficiency of the escapement system according to the invention, whereas a maximum of 50% of the available energy can be used without pretensioning in the starting position.

Mit der vorliegenden Erfindung kann somit ein Hemmungssystem mit konstanter Impulsenergie und hohem Wirkungsgrad erhalten werden.Thus, with the present invention, an escapement system with constant pulse energy and high efficiency can be obtained.

Eine bevorzugte Ausführungsform der vorliegenden Erfindung zeichnet sich dadurch aus, dass das Hemmungssystem mindestens ein ruhegebendes Element aufweist, welches mindestens eine Spannfläche aufweist, die bei einer Drehung des Hemmungsrads den Impulszahn von der Ausgangsposition in eine Spannposition überführt. Vorzugsweise weist das ruhegebende Momente zwei Spannflächen auf.A preferred embodiment of the present invention is characterized in that the escapement system has at least one resting element which has at least one clamping surface which is at a Rotation of the escape wheel moves the pulse tooth from the home position to a cocking position. The quiescent moment preferably has two clamping surfaces.

Besonders bevorzugt ist es, dass der Impulszahn durch Drehung des Hemmungsrades mit einem Drehmoment, welches größer als das Vorspannmoment des mindestens einen Federelements in der Ausgangsposition des mindestens einen Impulszahns ist, so gegen die mindestens eine Spannfläche gedrückt werden kann, dass er aus der Ausgangsposition heraus in die Spannposition bewegt wird und sich dabei das Vorspannmoment des mindestens einen Federelements erhöht.It is particularly preferred that the impulse tooth can be pressed against the at least one clamping surface by rotating the escapement wheel with a torque that is greater than the pretensioning moment of the at least one spring element in the starting position of the at least one impulse tooth so that it can be pushed out of the starting position is moved into the clamping position and thereby increases the biasing torque of the at least one spring element.

Vorzugsweise ist das mindestens eine ruhegebende Element als Anker, als Ruhehebel oder als Teil einer Unruhe ausgeführt.The at least one resting element is preferably designed as an anchor, as a resting lever or as part of a balance.

Weiterhin ist es bevorzugt, dass der mindestens eine Impulszahn eine Ausgangsposition einnimmt, in der er so fixiert ist, dass das Federelement ein Vorspannmoment aufweist. Dies bedeutet, dass der mindestens eine Impulszahn eine Ausgangsposition besitzt, in der er so fixiert ist, dass das Federelement ein Vorspannmoment aufweist, und diese Ausgangsposition einnimmt. Natürlich ist es hierbei immer noch möglich, dass der Impulszahn aus der Ausgangsposition in eine andere Position, z.B. die Spannposition, bewegt wird.Furthermore, it is preferred that the at least one impulse tooth assumes an initial position in which it is fixed in such a way that the spring element has a pretensioning moment. This means that the at least one pulse tooth has an initial position in which it is fixed in such a way that the spring element has a pretensioning moment and assumes this initial position. Of course, it is still possible that the impulse tooth is moved from the starting position to another position, e.g. the clamping position.

Es ist besonders bevorzugt, dass der mindestens eine Impulszahn bzw. die Impulszähne in jeder Position, die er einnehmen kann bzw. sie einnehmen können, ein (Vorspann-)Moment > 0 aufweist.It is particularly preferred that the at least one impulse tooth or the impulse teeth have a (preload) moment > 0 in every position that it or they can assume.

Gemäß der Erfindung weist das Hemmungsrad mehrere Impulszähne auf. Gemäß der Erfindung ist jeder der Impulszähne jeweils über ein Federelement mit der Antriebsachse verbunden. Alternativ ist es auch möglich, dass einer, mehrere oder alle der Impulszähne jeweils über ein oder mehrere Federelemente mit der Antriebsachse verbunden sind. Ferner ist es bevorzugt, dass jeder der Impulszähne mit dem jeweiligen Federelement, über das er mit der Antriebsachse verbunden ist, einstückig ausgebildet ist.According to the invention, the escapement wheel has a plurality of impulse teeth.

Dieses Prinzip kann auf die verschiedensten Hemmungstypen angewendet werden:

  • Ankerhemmungen:
    Der Impuls wird via Zwischenelement vom Hemmungsrad auf die Unruhe übertragen.
    1. a.) Es kommt ein Element zum Einsatz, welches Impulsfläche und Spannfläche und ruhegebende Fläche aufweist
    2. b.) Es kommen zwei Elemente zum Einsatz, eines weist die Impulsfläche und Spannfläche auf, ein weiteres die ruhegebende Fläche.
  • Chronometerhemmungen:
    Der Impuls wird direkt vom Hemmungsrad auf die Unruhe übertragen, welche somit die Impulsfläche aufweist.
    1. a.) Es gibt einen Ruhehebel, der Spannfläche und Ruhefläche aufweist und temporär mit der Unruhe in kontakt steht
    2. b.) Es gibt einen Spannhebel, der die Spannfläche aufweist und temporär mit der Unruhe im Kontakt steht, außerdem gibt es einen Ruhehebel, der durch die Unruhe oder den Impulszahn betätigt wird.

    Der Impuls wird direkt vom Hemmungsrad auf die Unruhe übertragen, welche somit die Impulsfläche aufweist.
    1. a.) Spannfläche und Ruhefläche sind ebenfalls Bestandteile der Unruhe
    2. b.) Spannfläche und Ruhefläche liegen auf einem separatem Element, welches permanent mit der Unruhe in Kontakt steht
    3. c.) Spannfläche ist Bestandteil der Unruhe, die Ruhefläche lieg auf einem separatem Element, welches permanent mit der Unruhe in Kontakt steht
This principle can be applied to a wide variety of escapement types:
  • anchor escapements:
    The impulse is transmitted from the escapement wheel to the balance via an intermediate element.
    1. a.) An element is used which has an impulse surface, a clamping surface and a resting surface
    2. b.) Two elements are used, one has the impulse surface and clamping surface, another the resting surface.

Anhand der nachfolgenden Beispiele und Figuren soll die vorliegende Erfindung näher erläutert werden, ohne diese auf die hier gezeigten spezifischen Ausführungsformen und Parameter zu beschränken.The present invention is to be explained in more detail on the basis of the following examples and figures, without restricting it to the specific embodiments and parameters shown here.

Im Folgenden wird die Funktion des erfindungsgemäßen Hemmungssystems anhand der Figuren beispielhaft in einer der "Schweizer Ankerhemmung" ähnlichen "Konstant-Energie Hemmung" erörtert.The function of the escapement system according to the invention is explained below with reference to the figures by way of example in a "constant-energy escapement" similar to the "Swiss lever escapement".

In Fig. 1 ist zunächst eine spezielle Ausführungsform des erfindungsgemäßen Hemmungssystems gezeigt. Das Hemmungssystem umfasst hierbei eine Antriebsachse 11 und ein Hemmungsrad, welches mehrere Impulszähne 1, 8 aufweist, wobei die Impulszähne 1, 8 mit der Antriebsachse 11 über Federelemente verbunden sind. Hierbei ist jeder der Impulszähne 1, 8 jeweils über ein Federelement mit der Antriebsachse 11 verbunden. Alternativ ist jedoch auch möglich, dass einer, mehrere oder alle der Impulszähne über ein oder mehrere Federelemente mit der Antriebsachse verbunden sind. Wie in Fig. 1a gezeigt, besitzen die Impulszähne eine Ausgangsposition, die sie einnehmen können, wie beispielhaft am Impulszahn 8 zu sehen ist. In dieser Ausgangsposition ist der Impulszahn so fixiert, dass das Federelement, über welches der Ruhezahn mit der Antriebsachse verbunden ist, ein Vorspannmoment aufweist. Die Impulszähne können jedoch auch eine Spannposition einnehmen, wie beispielhaft am Impulszahn 1 zu sehen ist.In 1 a special embodiment of the escapement system according to the invention is first shown. The escapement system here comprises a drive axle 11 and an escapement wheel, which has a plurality of impulse teeth 1, 8, the impulse teeth 1, 8 being connected to the drive axle 11 via spring elements. Each of the pulse teeth 1, 8 is connected to the drive axle 11 via a spring element. Alternatively, however, it is also possible for one, several or all of the impulse teeth to be connected to the drive axle via one or more spring elements. As shown in FIG. 1a, the pulse teeth have a starting position which they can assume, as can be seen at pulse tooth 8 by way of example. In this initial position, the impulse tooth is fixed in such a way that the spring element, via which the rest tooth is connected to the drive axle, has a pretensioning moment. However, the impulse teeth can also assume a clamped position, as can be seen in impulse tooth 1 as an example.

Das in Fig. 1 gezeigte Hemmungsrad ist zweiteilig ausgeführt ist. Es umfasst als ersten Teil ein Impulsrad, welches die Impulszähne 1, 8 aufweist, und als zweiten Teil ein Ruherad, welches Ruhezähne 3, 9 aufweist. In Fig. 2a sind beide Teile vor dem Zusammenbau des Hemmungsrads gezeigt. Hier sind die mit den Impulszähnen verbundenen Federelemente in einem entspannten Zustand. In Fig. 2b (wie auch in Fig. 1) sind die beiden Teile nach dem Zusammenbau und einem Verdrehen der Narben zueinander gezeigt. Das Impulsrad und das Ruherad sind hier in einer festen Position gegeneinander fixiert. Zudem werden die Impulszähne gegen auf dem Ruherad befindliche Anschläge 12, 13 gedrückt, so dass die Impulszähne in der Ausgangsposition fixiert sind, in welcher sie ein Vorspannmoment aufweisen.This in 1 The escapement wheel shown is made in two parts. As a first part, it comprises an impulse wheel, which has the impulse teeth 1, 8, and as a second part, a rest wheel, which has rest teeth 3, 9. In Figure 2a Both parts are shown before the escape wheel is assembled. Here the spring elements connected to the impulse teeth are in a relaxed state. In Figure 2b (as also in 1 ) the two parts are shown after assembly and twisting of the hubs towards each other. The momentum wheel and the rest wheel are fixed in a fixed position relative to each other. In addition the impulse teeth are pressed against stops 12, 13 located on the rest wheel, so that the impulse teeth are fixed in the starting position in which they have a pretensioning moment.

Zudem weist das in Fig. 1 gezeigte Hemmungsrad ein ruhegebendes Element 5 auf, wobei dieses als Anker ausgeführt ist. Das ruhegebende Element 5 weist zwei Spannflächen 2, 7 auf, die bei einer Drehung des Hemmungsrads die Impulszähne 1, 8 von der Ausgangsposition in die Spannposition überführen. Hierbei wird der jeweilige Impulszahn 1 durch Drehung des Hemmungsrades mit einem Drehmoment, welches größer als das Vorspannmoment des Federelements in der Ausgangsposition des Impulszahns 1 ist, so gegen die Spannfläche 2 gedrückt, dass er aus der Ausgangsposition heraus in die Spannposition bewegt wird und sich dabei das Vorspannmoment des Federelements erhöht, sowie dies in Fig. 1 am Beispiel des Impulszahns 1 gezeigt ist.In addition, the 1 shown escapement wheel on a resting element 5, which is designed as an anchor. The resting element 5 has two clamping surfaces 2, 7 which, when the escapement wheel rotates, move the impulse teeth 1, 8 from the initial position into the clamping position. Here, the respective impulse tooth 1 is pressed against the clamping surface 2 by turning the escapement wheel with a torque that is greater than the pretensioning moment of the spring element in the starting position of the impulse tooth 1, so that it is moved from the starting position into the clamping position and thereby moves increases the preload torque of the spring element, as well as this in 1 is shown using the example of pulse tooth 1.

Die Fig. 3a bis 6a sowie 3b bis 6b zeigen nun die Funktion des Hemmungssystems während der Drehung des Hemmungsrads durch die Antriebsachse. Die Figuren a und b der gleichen Nummer zeigen dabei das Hemmungssystem jeweils zum gleichen Zeitpunkt aus unterschiedlichen Perspektiven, einmal von vorne und einmal von hinten.the Figures 3a to 6a and Figures 3b to 6b now show the function of the escapement system during rotation of the escapement wheel by the drive axle. Figures a and b of the same number show the escapement system at the same time from different perspectives, one from the front and one from the back.

In den Fig. 3a und 3b ist der Impulszahn 1 durch die Spannfläche 2 an der ausgehenden Ankerseite auf ein höheres Moment MH gespannt. Gleichzeitig wird die Antriebsachse 11 des Hemmungsrades durch den Kontakt zwischen dem Ruhezahn 3 und der Ruhefläche 4 arretiert. Hierüber wird die Differenz zwischen dem Antriebsmoment MA und dem Vorspannmoment MH abgestützt.In the Figures 3a and 3b the impulse tooth 1 is clamped to a higher moment M H by the clamping surface 2 on the outgoing armature side. At the same time, the escapement wheel's drive axle 11 is locked by the contact between the resting tooth 3 and the resting surface 4 . This supports the difference between the drive torque M A and the preload torque M H .

Bewegt nun die Unruhe den Anker 5, kommt es zunächst zu der Freigabe des Impulszahns 1, sobald dieser nicht mehr auf der Spannfläche 2 ruht. Nach Freigabe des Impulszahns 1 trifft dieser auf die Hubfläche 6 und treibt den Anker 5 an, wie dies in den Figuren 4a und 4b gezeigt wird. Hierbei entspannt sich der Impulszahn 1 von seinem hohen Vorspannniveau MH auf sein niedriges Niveau ML. Gegen Ende oder nach der Energieabgabe ist die Spannfläche 7 durch die Ankerbewegung vor den Impulszahn 8 bewegt worden. Die Ruhefläche 4 gibt nun das Hemmungsrad für das Nachspannen frei, indem sie den Ruhezahn 3 frei gibt.If the balance now moves the anchor 5, the impulse tooth 1 is first released as soon as it no longer rests on the clamping surface 2. After the pulse tooth 1 has been released, it hits the lifting surface 6 and drives the armature 5, as is shown in FIGS Figures 4a and 4b will be shown. Here, the impulse tooth 1 relaxes from its high preload level M H to its low level M L . Towards the end or after the energy has been released, the clamping surface 7 has been moved in front of the impulse tooth 8 by the movement of the armature. The rest surface 4 now releases the escapement wheel for re-tensioning by releasing the rest tooth 3.

Es kommt nun - während die Unruhe ihren Ergänzungsbogen vollzieht - zu einer Bewegung der Antriebsachse 11, bis der Ruhezahn 9 auf die Ruhefläche 10 trifft, wie dies in den Figuren 5a und 5b gezeigt wird. Während dieses Vorgangs wird nun der Impulszahn 8 durch die Spannfläche 7 an der Eingangsseite Ankerseite vom Momentenniveau ML auf MH vorgespannt.It is now - while the unrest completes their supplementary arc - to a movement of the drive shaft 11 until the rest tooth 9 hits the rest surface 10, as in the Figures 5a and 5b will be shown. During this process, the impulse tooth 8 is now pretensioned by the clamping surface 7 on the input side, armature side, from the moment level M L to M H .

Bewegt nun wiederum die Unruhe den Anker 5, kommt es zur Freigabe des Impulszahns 8, sobald dieser nicht mehr auf der Spannfläche 7 ruht. Nach Freigabe des Impulszahns 8 trifft dieser auf die Hubfläche an der Eingangsseite des Ankers und treibt den Anker 5 an, wie dies in den Figuren 6a und 6b gezeigt wird. Hierbei entspannt sich der Impulszahn 8 von seinem hohen Vorspannniveau MH auf sein niedriges Niveau ML. Die Ruhefläche 10 gibt nun den Ruhezahn 9 des Ruherades frei, was das Vorspannen des nächsten Impulszahns auslöst.If the balance moves the anchor 5 again, the impulse tooth 8 is released as soon as it no longer rests on the clamping surface 7 . After the pulse tooth 8 is released, it hits the lifting surface on the input side of the armature and drives the armature 5, as shown in FIGS Figures 6a and 6b will be shown. Here, the impulse tooth 8 relaxes from its high preload level M H to its low level M L . The resting surface 10 now releases the resting tooth 9 of the resting wheel, which triggers the pretensioning of the next pulse tooth.

Ab hier wiederholen sich die Abläufe sobald die Unruhe einen weiteren Durchlauf der Ruhelage vollzieht.From here the processes are repeated as soon as the restlessness completes another pass through the rest position.

Für einen korrekten Ablauf ist es erforderlich, dass die Antriebsachse 11 des Hemmungsrades ein höheres Drehmoment MA abgibt, als zum Vorspannen des Impulszahns 1, 8 erforderlich ist. Durch ein von 0 Nm verschiedenes niedriges Vorspannmoment ML steigt die Effizienz der Hemmung maßgeblich, da mehr von der zum Spannen erforderlichen Energie (Δα · MA) gespeichert werden kann. Dies wird auch durch Fig. 7 veranschaulicht, welche das Energiediagramm der Hemmung zeigt. Dort wird gezeigt, dass aufgrund des hohen Vorspannniveaus ML der Impulszähne in der Ausgangsposition die Menge an übertragener Energie 14 im Vergleich zur Menge an verlorener Energie 15 sehr hoch ist. Aus dem Diagramm ist somit ohne Weiteres ersichtlich, dass ein möglichst hohes Vorspannmoment ML der Impulszähne in der Ausgangsposition maßgeblich zur Effizienz des erfindungsgemäßen Hemmungssystems beiträgt. Ohne Vorspannung in der Ausgangsposition könnten hingegen maximal 50% der verfügbaren Energie genutzt werden.For a correct process, it is necessary for the drive axle 11 of the escapement wheel to deliver a higher torque M A than is required for pretensioning the pulse tooth 1, 8. A low pretensioning torque M L other than 0 Nm significantly increases the efficiency of the escapement, since more of the energy required for tensioning (Δα · M A ) can be stored. This will also through 7 Figure 1 illustrates showing the energy diagram of the escapement. There it is shown that due to the high preload level M L of the impulse teeth in the home position, the amount of energy 14 transferred is very high compared to the amount of energy 15 lost. It is thus readily apparent from the diagram that the highest possible pretensioning moment M L of the impulse teeth in the starting position contributes significantly to the efficiency of the escapement system according to the invention. On the other hand, without pretensioning in the starting position, a maximum of 50% of the available energy could be used.
