Description

La présente invention concerne le domaine des mouvements horlogers mécaniques.The present invention relates to the field of mechanical watch movements.

Les mouvements horlogers mécaniques comprennent généralement, notamment, un barillet logeant un ressort moteur, un rouage entraîné par le barillet et dont les axes de certaines des roues portent des aiguilles indicatrices, un organe réglant tel qu'un balancier-spiral et, entre le rouage et l'organe réglant, un échappement pour entretenir les oscillations de l'organe réglant. L'échappement comprend une roue d'échappement entraînée par le rouage et un organe, tel qu'une ancre, située entre la roue d'échappement et l'organe réglant.Mechanical watch movements generally comprise, in particular, a barrel housing a mainspring, a train driven by the barrel and whose axes of some of the wheels carry indicator hands, a regulating member such as a balance-spring and, between the gear train and the regulating member, an escapement for maintaining the oscillations of the regulating member. The exhaust includes an escape wheel driven by the gear train and a member, such as an anchor, located between the escape wheel and the regulating member.

Les mouvements horlogers que l'on trouve actuellement sur le marché ont couramment un organe réglant oscillant à une fréquence de 4 Hz et une roue d'échappement à 20 dents. Il a également été commercialisé, sous la marque Zenith El Primero, un mouvement dont l'organe réglant oscille à une fréquence de 5 Hz et dont la roue d'échappement comporte, à la connaissance du déposant, 21 dents. Le document FR 2162504 divulgue différentes sortes de mouvements fonctionnant à des fréquences différentes.The watch movements currently found on the market currently have a regulating organ oscillating at a frequency of 4 Hz and a 20-tooth escapement wheel. It has also been marketed under the brand name Zenith El Primero, a movement whose regulating organ oscillates at a frequency of 5 Hz and whose escape wheel includes, to the applicant's knowledge, 21 teeth. The document FR 2162504 discloses different kinds of movements operating at different frequencies.

On sait dans le domaine horloger que plus la fréquence de l'organe réglant est grande plus la mesure du temps sera précise. Toutefois, une augmentation de la fréquence entraîne une augmentation de la vitesse angulaire de rotation de la roue d'échappement et nécessite donc de modifier le rouage, plus précisément les rapports d'engrenage, pour que les aiguilles indicatrices tournent à la bonne vitesse. L'augmentation de la vitesse de rotation de la roue d'échappement a également pour effet de diminuer la réserve de marche car le ressort moteur se détend plus rapidement.It is known in the watch industry that the higher the frequency of the regulating organ, the more accurate the time measurement will be. However, an increase in the frequency causes an increase in the angular speed of rotation of the escape wheel and therefore requires to modify the gear, specifically the gear ratios, so that the indicator hands turn at the right speed. Increasing the speed of rotation of the escape wheel also has the effect of reducing the power reserve as the mainspring expands more rapidly.

La présente invention vise à permettre l'obtention d'un mouvement horloger qui puisse fonctionner à une fréquence élevée sans présenter les inconvénients susmentionnés.The present invention aims to provide a watch movement that can operate at a high frequency without the aforementioned disadvantages.

A cette fin, il est prévu un procédé de réalisation d'au moins deux mouvements horlogers fonctionnant à des fréquences d'oscillation différentes, caractérisé en ce qu'il comprend la conception d'une base commune aux mouvements, la base commune comprenant un rouage servant à relier un barillet à un échappement dans chaque mouvement, et la sélection, pour chacun desdits mouvements, d'un ensemble organe réglant - échappement comprenant un organe réglant ayant une fréquence d'oscillation f et un échappement pour entretenir les oscillations de l'organe réglant, l'échappement comprenant une roue d'échappement à N dents, la fréquence d'oscillation f et le nombre de dents N étant différents d'un mouvement à l'autre et le rapport entre N et f étant sensiblement le même d'un mouvement à l'autre.To this end, there is provided a method for producing at least two watch movements operating at different oscillation frequencies, characterized in that it comprises the design of a base common to the movements, the common base comprising a gear train apparatus for connecting a cylinder to an exhaust in each movement, and selecting, for each of said movements, a regulating-exhausting body assembly comprising a regulating member having an oscillation frequency f and an exhaust for sustaining oscillations of the a regulating member, the escapement comprising an N-tooth escape wheel, the oscillation frequency f and the number of teeth N being different from one movement to the other and the ratio between N and f being substantially the same, one movement to another.

Ainsi, dans la présente invention, la fréquence de l'organe réglant peut être augmentée d'un mouvement à l'autre sans augmenter le rapport entre le nombre de dents N de la roue d'échappement et la fréquence f, rapport qui peut être égal à une valeur usuelle. La vitesse angulaire de rotation de la roue d'échappement reste donc inchangée d'un mouvement à l'autre, permettant au rouage et plus généralement à l'ensemble du mouvement à l'exception de l'organe réglant et de l'échappement de rester inchangés. La réserve de marche est également conservée.Thus, in the present invention, the frequency of the regulating member can be increased from one movement to another without increasing the ratio between the number of teeth N of the escape wheel and the frequency f, which ratio can be equal to a usual value. The angular speed of rotation of the escape wheel therefore remains unchanged from one movement to the other, allowing the gear and more generally to the entire movement with the exception of the regulating member and the exhaust of remain unchanged. The power reserve is also preserved.

Typiquement, les mouvements sont réalisés de manière que l'échappement de chaque mouvement comprenne en outre une ancre située entre la roue d'échappement et l'organe réglant, et que la distance entre les centres de rotation de la roue d'échappement et de l'ancre soit sensiblement la même d'un mouvement à l'autre et la distance entre les centres de rotation de l'ancre et de l'organe réglant soit sensiblement la même d'un mouvement à l'autre. De cette manière, les platines et ponts sur lesquels sont montés les différents organes peuvent être les mêmes d'un mouvement à l'autre.Typically, the movements are made so that the exhaust of each movement further comprises an anchor located between the escape wheel and the regulating member, and that the distance between the centers of rotation of the escape wheel and the the anchor is substantially the same from one movement to another and the distance between the centers of rotation of the anchor and the regulating member is substantially the same from one movement to another. In this way, the plates and bridges on which are mounted the different organs can be the same from one movement to another.

Les mouvements peuvent même être réalisés de manière à être sensiblement entièrement identiques à l'exception de leur échappement et de leur organe réglant.The movements can even be made to be substantially identical except for their escapement and their regulating organ.

Ledit rapport entre le nombre de dents N et la fréquence f, mesurée en Hertz, est typiquement sensiblement égal à 5. De préférence, au moins l'une des fréquences f est au moins égale à environ 5 Hz, de préférence au moins égale à environ 6 Hz, de préférence encore au moins égale à environ 8 Hz, de préférence encore au moins égale à environ 10 Hz.Said ratio between the number of teeth N and the frequency f, measured in Hertz, is typically substantially equal to 5. Preferably, at least one of the frequencies f is at least equal to approximately 5 Hz, preferably at least equal to about 6 Hz, more preferably at least about 8 Hz, more preferably at least about 10 Hz.

On observera qu'avec la présente invention il est possible de concevoir des ensembles organe réglant - échappement différents et interchangeables, pour permettre à des mouvements horlogers de même conception de fonctionner à des fréquences différentes. En d'autres termes, on peut concevoir ladite base commune pour plusieurs mouvements, et ensuite choisir, pour chacun d'entre eux, un ensemble organe réglant - échappement pour le faire fonctionner à une fréquence souhaitée.It will be observed that with the present invention it is possible to design different and interchangeable regulating-exhaust member assemblies, to allow watch movements of the same design to operate at different frequencies. In other words, one can design said common base for several movements, and then choose, for each of them, a set regulating body - exhaust to operate at a desired frequency.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description détaillée suivante faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue plane de dessus schématique d'une partie d'un mouvement horloger traditionnel,
  • la figure 2 est une vue en perspective d'un ensemble d'une roue d'échappement et d'une ancre d'échappement selon l'invention, coopérant l'une avec l'autre,
  • la figure 3 est une vue en perspective d'un autre ensemble d'une roue d'échappement et d'une ancre d'échappement selon l'invention, coopérant l'une avec l'autre.
Other features and advantages of the present invention will appear on reading the following detailed description given with reference to the accompanying drawings in which:
  • the figure 1 is a schematic top plan view of part of a traditional watch movement,
  • the figure 2 is a perspective view of a set of an escape wheel and an escape anchor according to the invention, cooperating with each other,
  • the figure 3 is a perspective view of another set of an escape wheel and an escape anchor according to the invention, cooperating with each other.

Dans le cadre de la présente invention, on entend par « dent » une dent de la roue d'échappement ayant un rôle fonctionnel, c'est-à-dire, dans le cas d'un échappement à ancre, une dent qui coopère avec les palettes de l'ancre.In the context of the present invention, the term "tooth" means a tooth of the escape wheel having a functional role, that is to say, in the case of an anchor escapement, a tooth which cooperates with the pallets of the anchor.

En référence à la figure 1, un mouvement horloger traditionnel 1 comprend notamment un ressort moteur (non représenté) logé dans un barillet 2, un rouage 3 entraîné par le barillet 2, un organe réglant de type balancier-spiral 4 (dont seul le balancier est représenté) et, entre le rouage 3 et le balancier-spiral 4, un échappement 5. L'échappement 5 comprend une roue d'échappement 6 et un pignon d'échappement 7 qui est solidaire de la roue 6 et qui engrène avec une roue de seconde 8 du rouage 3 pour entraîner la roue 6. L'échappement 5 comprend en outre un organe 9, par exemple une ancre, qui coopère avec la roue d'échappement 6 et avec une cheville de plateau 10 solidaire de l'axe du balancier-spiral 4 pour entretenir les oscillations du balancier-spiral 4. Les axes respectifs de certaines des roues du rouage 3, à savoir la roue de seconde 8, une roue des minutes et une roue des heures (non représentées), sont destinés à porter des organes indicateurs des secondes, des minutes et des heures, typiquement des aiguilles, se déplaçant au-dessus d'un cadran de montre. Tous ces éléments sont bien connus de l'homme du métier et ne seront donc pas décrits plus en détail.With reference to the figure 1 a traditional watch movement 1 comprises in particular a motor spring (not shown) housed in a barrel 2, a gear train 3 driven by the barrel 2, a regulating member of the balance-spring type 4 (of which only the balance is shown) and, the gear train 3 and the sprung balance 4, an exhaust 5. The exhaust 5 comprises an escape wheel 6 and an exhaust pinion 7 which is secured to the wheel 6 and which meshes with a second wheel 8 of the gear train 3 to drive the wheel 6. The exhaust 5 further comprises a member 9, for example an anchor, which cooperates with the escape wheel 6 and with a plate pin 10 secured to the axis of the balance-spring 4 for maintain the oscillations of the sprung balance 4. The respective axes of some of the wheels of the train 3, namely the second wheel 8, a minute wheel and a wheel hours (not shown), are intended to carry the indicators of seconds, minutes and hours s, typically needles, moving over a watch face. All these elements are well known to those skilled in the art and will not be described in more detail.

Une manière connue d'augmenter la fréquence d'oscillation d'un balancier-spiral est d'augmenter la raideur du spiral et/ou de diminuer le moment d'inertie du balancier. Pour augmenter la raideur du spiral, on peut par exemple le raccourcir ou augmenter sa section. La diminution du moment d'inertie du balancier s'obtient par exemple en allégeant le balancier et/ou en diminuant son rayon de giration.One known way to increase the oscillation frequency of a balance spring is to increase the stiffness of the balance spring and / or to reduce the moment of inertia of the balance. To increase the stiffness of the hairspring, it can for example shorten or increase its section. The decrease of the moment of inertia of the pendulum is obtained for example by lightening the balance and / or decreasing its radius of gyration.

Dans la présente invention, l'augmentation de la fréquence du balancier-spiral s'accompagne d'une augmentation du nombre de dents de la roue d'échappement. Les techniques de fabrication actuelles permettent la réalisation de roues avec un grand nombre de dents. La figure 2 montre une roue d'échappement 11 et une ancre d'échappement 12 faisant partie d'un échappement selon l'invention. La roue d'échappement 11 comporte 50 dents et l'échappement dont elle fait partie est destiné à fonctionner avec un balancier-spiral oscillant à une fréquence de 10 Hz (72000 alternances par heure). La figure 3 montre une roue d'échappement 13 et une ancre d'échappement 14 faisant partie d'un autre échappement selon l'invention. La roue d'échappement 13 comporte 40 dents et l'échappement dont elle fait partie est destiné à fonctionner avec un balancier-spiral oscillant à une fréquence de 8 Hz (57600 alternances par heure). De manière similaire, on peut aussi réaliser par exemple un échappement ayant une roue d'échappement à 30 dents et destiné à fonctionner avec un balancier-spiral oscillant à une fréquence de 6 Hz (43200 alternances par heure), ou un échappement ayant une roue d'échappement à 25 dents et destiné à fonctionner avec un balancier-spiral oscillant à une fréquence de 5 Hz (36000 alternances par heure).In the present invention, the increase in the frequency of the sprung balance is accompanied by an increase in the number of teeth of the escape wheel. Current manufacturing techniques allow the realization of wheels with a large number of teeth. The figure 2 shows an escape wheel 11 and an exhaust anchor 12 forming part of an exhaust according to the invention. The escape wheel 11 has 50 teeth and the exhaust of which it is part is intended to operate with a sprung balance oscillating at a frequency of 10 Hz (72000 vibrations per hour). The figure 3 shows an escape wheel 13 and an exhaust anchor 14 forming part of another exhaust according to the invention. The escape wheel 13 has 40 teeth and the exhaust of which it is part is intended to operate with a sprung balance oscillating at a frequency of 8 Hz (57600 vibrations per hour). Similarly, it is also possible to produce, for example, an exhaust having a 30-tooth escapement wheel intended to operate with a balance-spring oscillating at a frequency of 6 Hz (43,200 vibrations per hour), or an escapement having a wheel Exhaust system with 25 teeth and intended to operate with a sprung balance oscillating at a frequency of 5 Hz (36000 vibrations per hour).

Il est possible de conformer les dents des roues d'échappement pour que la même ancre puisse être utilisée avec plusieurs de ces roues d'échappement. Ainsi, les ancres 12 et 14 illustrées aux figures 2 et 3 peuvent être identiques bien qu'elles coopèrent avec des roues d'échappement qui sont différentes.It is possible to conform the teeth of the exhaust wheels so that the same anchor can be used with several of these escape wheels. Thus, the anchors 12 and 14 illustrated at Figures 2 and 3 may be identical although they cooperate with different exhaust wheels.

On voit que dans les exemples indiqués ci-dessus le rapport entre le nombre de dents de la roue d'échappement et la fréquence du balancier-spiral est égal à 5, soit la valeur que l'on rencontre couramment dans les mouvements actuels. La vitesse angulaire de rotation de la roue d'échappement est donc la même que dans les mouvements usuels. Il en découle qu'un mouvement incluant l'un des échappements décrits ci-dessus et le balancier-spiral correspondant pourra avoir un rouage usuel, par exemple le rouage 3 illustré à la figure 1.It can be seen that in the examples indicated above, the ratio between the number of teeth of the escape wheel and the frequency of the spring balance is equal to 5, which is the value that is commonly encountered in the current movements. The angular speed of rotation of the escape wheel is therefore the same as in the usual movements. It follows that a movement including one of the exhausts described above and the balance sprung-balance may have a conventional wheel, for example the wheel 3 illustrated in the figure 1 .

De préférence, les entraxes de l'échappement, c'est-à-dire les distances entre le centre de rotation de la roue d'échappement et le centre de rotation de l'ancre et entre le centre de rotation de l'ancre et le centre de rotation du balancier, sont conservés d'un échappement à l'autre et sont égaux à des valeurs usuelles. Ainsi, en particulier, l'entraxe d3 de la roue d'échappement 11 et de l'ancre 12 est égal à l'entraxe d5 de la roue d'échappement 13 et de l'ancre 14 et à l'entraxe d1 de la roue d'échappement usuelle 6 et de l'ancre usuelle 9. De manière similaire, l'entraxe d4 de l'ancre 12 et du balancier correspondant est égal à l'entraxe d6 de l'ancre 14 et du balancier correspondant et à l'entraxe d2 de l'ancre usuelle 9 et du balancier usuel 4. En conservant les mêmes entraxes d'un échappement à l'autre, on facilite l'interchangeabilité de l'ensemble échappement - organe réglant dans un mouvement donné et on permet à des mouvements incluant respectivement des échappements tels que décrits ci-dessus avec les balanciers-spiraux correspondants d'avoir des platines et ponts identiques.Preferably, the distances from the exhaust, that is to say the distances between the center of rotation of the escape wheel and the center of rotation of the anchor and between the center of rotation of the anchor and the center of rotation of the balance, are preserved from one exhaust to the other and are equal to usual values. Thus, in particular, the center distance d3 of the escape wheel 11 and the anchor 12 is equal to the center distance d5 of the escape wheel 13 and the anchor 14 and to the center distance d1 of the usual escape wheel 6 and the usual anchor 9. Similarly, the center distance d4 of the anchor 12 and the corresponding balance is equal to the center distance d6 of the anchor 14 and corresponding balance and at the center distance d2 of the usual anchor 9 and the usual balance wheel 4. Keeping the same distances from one exhaust to the other, it facilitates the interchangeability of the exhaust assembly - regulating organ in a given movement and allows movements including respectively escapements as described above with the corresponding balance springs to have identical plates and bridges.

De manière plus générale, on peut réaliser des mouvements entièrement identiques, à l'exception de leur échappement et de leur balancier-spiral, et régulés par des oscillations de fréquences différentes. Le fait que toute la partie du mouvement autre que l'échappement et le balancier-spiral ne change pas d'un mouvement à l'autre réduit considérablement les coûts de développement, de production et de logistique. Il est possible par exemple de reprendre un mouvement existant et de n'y changer que l'échappement et le balancier-spiral pour augmenter sa fréquence de régulation.More generally, it is possible to perform entirely identical movements, with the exception of their escapement and their sprung balance, and regulated by oscillations of different frequencies. The fact that the entire part of the movement other than the escapement and the sprung balance does not change from one movement to the other greatly reduces the costs of development, production and logistics. It is possible for example to resume an existing movement and to change only the exhaust and the sprung balance to increase its frequency of regulation.

Dans les exemples représentés, l'échappement selon l'invention est un échappement à ancre suisse. Toutefois, la présente invention pourrait s'appliquer à d'autres types d'échappements à ancre et plus généralement à d'autres types d'échappement.In the examples shown, the escapement according to the invention is a Swiss lever escapement. However, the present invention could be applied to other types of anchor escapements and more generally to other types of escapement.
