Description
L'invention concerne un oscillateur horloger comportant une structure ou/et un cadre, et une pluralité de résonateurs primaires et distincts, déphasés temporellement et géométriquement, et comportant chacun au moins une masse inertielle rappelée vers ladite structure ou vers ledit cadre par un moyen de rappel élastique.The invention relates to a clock oscillator comprising a structure and / or a frame, and a plurality of primary and distinct resonators, temporally and geometrically out of phase, and each comprising at least one inertial mass biased towards said structure or towards said frame by means of elastic return.
L'invention concerne encore un mouvement d'horlogerie comportant au moins un tel oscillateur horloger.The invention also relates to a watch movement comprising at least one such watch oscillator.
L'invention concerne une montre comportant au moins un tel mouvement.The invention relates to a watch comprising at least one such movement.
L'invention concerne le domaine des oscillateurs d'horlogerie pour montres, notamment pour des mouvements mécaniques.The invention relates to the field of watch oscillators for watches, in particular for mechanical movements.
La plupart des montres mécaniques actuelles comportent un échappement à ancre suisse. Les deux fonctions principales de l'échappement sont:
- l'entretien des va-et-vient du résonateur, constitué par un ensemble balancier-spiral ;
- le comptage de ces va-et-vient.
- maintenance of the comings and goings of the resonator, constituted by a pendulum-balance assembly;
- Counting these back and forth.
En plus de ces deux fonctions, l'échappement doit être robuste, et résister aux chocs, et constitué de façon à éviter de coincer le mouvement (renversement).In addition to these two functions, the exhaust must be robust, shock-resistant, and constructed to prevent entrapment (overturning).
L'échappement à ancre suisse a un rendement énergétique faible, de l'ordre de 30%. Ce faible rendement provient du fait que les mouvements de l'échappement sont saccadés, et du fait que plusieurs pièces se transmettent leur mouvement via des plans inclinés qui frottent les uns par rapport aux autres.The Swiss lever escapement has a low fuel efficiency of around 30%. This low yield is due to the fact that the movements of the exhaust are jerky, and that several parts are transmitted their movement via inclined planes that rub against each other.
La présente invention a pour objectif de proposer un système d'échappement à haut rendement. On propose également un oscillateur sans pivot et sans réaction au support permettant d'atteindre de très haut facteur de qualité.The present invention aims to provide a high efficiency exhaust system. We also propose a oscillator without pivot and without reaction to the support to achieve a very high quality factor.
Pour atteindre ce but, l'invention consiste dans la mise au point d'une architecture permettant des interactions continues, sans saccades, entre résonateur et roue d'échappement. On doit, pour ce faire, concéder l'utilisation d'au moins un deuxième résonateur déphasé par rapport à un premier résonateur.To achieve this goal, the invention consists in the development of an architecture for continuous interactions, without saccades, between resonator and escape wheel. To do this, we must concede the use of at least a second resonator out of phase with respect to a first resonator.

L'invention concerne une montre mécanique 200 munie de résonateurs équilibrés, déphasés et entretenus de manière continue.The invention relates to a
L'invention concerne un oscillateur horloger 1 comportant une structure 2 ou/et un cadre 4, et une pluralité de résonateurs primaires 10 et distincts.The invention relates to a
Ces résonateurs primaires 10 sont déphasés temporellement et géométriquement. Ils comportent chacun au moins une masse inertielle 5, qui est rappelée vers la structure 2, ou le cadre 4, par un moyen de rappel élastique 6. On entend en effet par « résonateurs distincts » que chaque résonateur primaire 10 possède sa propre masse inertielle 5 et son propre moyen de rappel élastique 6, notamment un ressort.These primary resonators 10 are phase-shifted temporally and geometrically. They each comprise at least one
Selon l'invention, cet oscillateur horloger 1 comporte des moyens de couplage 11, qui sont agencés pour permettre l'interaction des résonateurs primaires 10. Ces moyens de couplage 11 comportent des moyens moteurs 12, lesquels sont agencés pour entraîner en mouvement un mobile 13. Ce mobile 13 comporte des moyens d'entraînement et de guidage 14, qui sont agencés pour entraîner et guider, de préférence de façon prisonnière, un moyen de commande 15. Ce moyen de commande 15 est articulé avec une pluralité de moyens de transmission 16, chacun articulé, à distance du moyen de commande 15, avec une masse inertielle 5 d'un résonateur primaire 10.According to the invention, this
De plus, les résonateurs primaires 10 et le mobile 13 sont agencés de telle façon que les axes des articulations de deux quelconques des résonateurs primaires 10 et l'axe d'articulation du moyen de commande 15 ne sont jamais coplanaires. En d'autres termes, les projections de ces axes selon un plan perpendiculaire commun ne sont jamais alignées. On comprend que les axes d'articulation peuvent, dans certaines réalisations, être des axes de pivots virtuels.In addition, the primary resonators 10 and the mobile 13 are arranged such that the axes of the joints of any two of the primary resonators 10 and the axis of articulation of the control means 15 are never coplanar. In other words, the projections of these axes in a common perpendicular plane are never aligned. It is understood that the axes of articulation may, in some embodiments, be virtual pivot axes.
Dans les variantes non limitatives de réalisation illustrées aux
On comprend que le mobile 13 se substitue à une roue d'échappement classique, et est préférentiellement en aval d'un rouage de finissage alimenté par un barillet ou similaire.It is understood that the mobile 13 replaces a conventional escape wheel, and is preferably downstream of a finishing train powered by a barrel or the like.
Les moyens de transmission 16 peuvent en particulier être réalisés sous la forme de bielles 160, comportant chacune une première articulation 161 avec le moyen de commande 15, et une deuxième articulation 162 avec la masse inertielle 5 considérée. La première articulation 161 et la deuxième articulation 162 définissent ensemble une direction de bielle. Selon l'invention, toutes les directions de bielle font deux à deux, à tout instant, un angle différent de zéro ou π. Autrement formulé, le produit vectoriel des deux directions de bielles est différent de zéro.The transmission means 16 may in particular be made in the form of connecting rods 160, each having a
Dans une application particulière, les moyens de transmission 16 sont des bielles 160 non colinéaires. Le mobile 13, soumis à un couple moteur, et les moyens de couplage 11 ont une géométrie d'interaction, qui permet de transmettre essentiellement des forces tangentielles à ces bielles 160.In a particular application, the transmission means 16 are non-collinear connecting rods 160. The mobile 13, subjected to a driving torque, and the coupling means 11 have an interaction geometry, which allows to essentially transmit tangential forces to these rods 160.
On appelle ci-après résonateurs élémentaires des résonateurs constituant ensemble un résonateur primaire: ils sont montés en diapason, de telle façon que les réactions et les erreurs s'annulent. Quand un nombre n de résonateurs élémentaires constituent ensemble un résonateur primaire, ils sont déphasés entre eux de 2π/n.Elementary resonators are termed resonators that together constitute a primary resonator: they are mounted in a tuning fork so that the reactions and errors cancel each other out. When a number n of elementary resonators together constitute a primary resonator, they are out of phase with each other by 2π / n.
La
Dans une application particulière préférée, mais non limitative, et illustrée par les figures, les résonateurs primaires 10 sont des résonateurs rotatifs.In a particular preferred application, but not limited to, and illustrated by the figures, the primary resonators 10 are rotary resonators.
La
Pour obtenir un meilleur facteur de qualité, l'oscillateur 1 est agencé de façon à ce que les forces et les couples de réactions des résonateurs primaires 10 sur le support 2 (ou sur le cadre 4 s'ils sont tous fixés sur un tel cadre) s'annulent. Les forces s'annulent parce que le centre de masse ne bouge pas, quand l'axe de rotation passe par le centre de masse. Les couples s'annulent car chaque composant en rotation est compensé par un autre composant en rotation inverse. Le couplage entre les résonateurs peut se faire via un encastrement flexible comme dans un diapason ou via les bielles 160, ou, plus généralement, les moyens de transmission 16. Le couplage des résonateurs primaires 10 les uns par rapport aux autres se fait alors par un encastrement flexible de chacun des résonateurs primaires 10 par rapport à la structure commune 2 ou au cadre 4.To obtain a better quality factor, the
Ainsi, de préférence, la résultante des efforts et couples de réaction des résonateurs primaires 10 par rapport à la structure commune 2 ou au cadre 4, à laquelle ou auquel ils sont fixés, est nulle.Thus, preferably, the resultant of the efforts and reaction torques of the primary resonators 10 with respect to the
Pour un fonctionnement optimal, les résonateurs primaires rotatifs 10 sont agencés de façon à ce que leurs centres de masse restent en position fixe, au moins lors des oscillations normales de ces résonateurs primaires 10. L'oscillateur horloger 1 comporte de préférence des moyens de butée pour limiter leur course en cas de choc ou similaire.For optimum operation, the primary rotary resonators 10 are arranged so that their centers of mass remain in a fixed position, at least during the normal oscillations of these primary resonators 10. The
De préférence, ces résonateurs primaires 10 ont au moins un mode de résonance identique, ils sont agencés pour vibrer selon un déphasage entre eux de la valeur 2π/n, où n est leur nombre, et ils sont agencés selon une symétrie dans l'espace telle que la résultante des efforts et des couples appliqués par les résonateurs primaires 10 sur la structure 2, ou sur un cadre 4 qui les supporte, est nulle.Preferably, these primary resonators 10 have at least one identical resonance mode, they are arranged to vibrate in a phase shift between them of the value 2π / n, where n is their number, and they are arranged according to a symmetry in space such that the resultant of the forces and torques applied by the primary resonators 10 on the
Dans une application particulière, tel que visible sur les figures, les résonateurs primaires 10 sont en nombre pair, et ils constituent deux à deux des paires dans lesquelles les masses inertielles 5 sont en mouvement déphasé de π l'un par rapport à l'autre.In a particular application, as can be seen in the figures, the primary resonators 10 are even in number, and they constitute pairs of pairs in which the
Dans un agencement particulier, tel que visible sur les
Ces résonateurs élémentaires 810 ont au moins un mode de résonance identique, et sont agencés pour vibrer selon un déphasage entre eux de la valeur 2π/n, où n est le nombre des résonateurs élémentaires 810. Ils sont agencés selon une symétrie dans l'espace, telle que la résultante des efforts et des couples appliqués par les résonateurs élémentaires 810 sur la traverse 804 est nulle.These elementary resonators 810 have at least one identical resonance mode, and are arranged to vibrate in a phase shift between them of the value 2π / n, where n is the number of elementary resonators 810. They are arranged according to a symmetry in space , such that the resultant of the forces and torques applied by the elementary resonators 810 on the cross member 804 is zero.
Cette traverse 804 est fixée au support fixe 2 par une liaison élastique principale élémentaire 803, dont la rigidité est supérieure à la rigidité de chaque lame flexible élastique élémentaire 806, et dont l'amortissement est supérieur à l'amortissement de chaque lame flexible élémentaire 806. Et les résonateurs élémentaires 810 sont agencés dans l'espace de manière à ce que la résultante de leurs erreurs de marche dues à la gravitation soit nulle.This cross member 804 is fixed to the fixed
Plus particulièrement, au moins un des résonateurs primaires 10 est constitué d'une paire de tels résonateurs élémentaires 810. Dans cette paire, les masses inertielles élémentaires 805 sont en mouvement déphasé de π l'un par rapport à l'autre.More particularly, at least one of the primary resonators 10 consists of a pair of such elementary resonators 810. In this pair, the elementary inertial masses 805 are in phase-shifting π relative to one another.
Plus particulièrement encore, cette paire est constituée de résonateurs élémentaires 810 identiques, qui sont en opposition géométrique et de phase l'un par rapport à l'autre.More particularly, this pair consists of identical elementary resonators 810, which are geometrically opposed and phase to each other.
Dans le cas particulier des
Dans la variante de la
Pour chaque résonateur primaire 10A, 10B, au moins la liaison élastique principale 3A, respectivement 3B, la traverse 40A, respectivement 40B, les lames flexibles élastiques 61 A, 62A, respectivement 61 B, 62B, forment ensemble une structure monolithique primaire plane, en silicium, ou silicium oxydé, ou quartz, ou DLC, ou similaire, qui, dans la position de repos du mécanisme oscillateur isochrone 1, est symétrique par rapport à un plan de symétrie. Avantageusement, le support fixe 2 forme un ensemble monolithique avec ces deux structures monolithiques primaires.For each
La traverse 40A, respectivement 40B, porte une paire de masses 5, repérées 51 A et 52 A, respectivement 51B et 52 B, montées de façon symétrique de part et d'autre du support fixe 2 et de la liaison élastique principale 3A, respectivement 3B. Chacune de ces masses est montée de façon oscillante et rappelée par une lame flexible élastique 61 A, 62A, respectivement 61 B, 62B, qui est un spiral, ou encore un assemblage de spiraux. Ces spiraux sont, chacun, lié directement ou indirectement à une masse au niveau de leur spire interne, et attachés à la traverse 40A, respectivement 40B, par sa spire externe. Chaque masse pivote autour d'un axe de pivotement virtuel de position déterminée par rapport à la traverse 40A, respectivement 40B. Chaque axe de pivotement virtuel est, en position de repos du mécanisme oscillateur isochrone 1, confondu avec le centre de masse, de la masse respective. Les masses s'étendent sensiblement parallèlement l'une à l'autre en position au repos, selon une direction transversale. Pour limiter le déplacement des centres de masse à une course transversale par rapport à la traverse 4, aussi réduite que possible dans cette direction transversale Y, et à une course longitudinale selon une direction longitudinale (perpendiculaire à cette direction transversale) qui est supérieure à cette course transversale, chaque spiral est à section ou courbure variable le long de son développement.The

Chaque résonateur primaire 10A, 10B, ainsi rendu isochrone par l'une de ces combinaisons particulières de résonateurs élémentaires, comporte avantageusement des butées en rotation, ou/et des butées de limitation de translation selon les directions longitudinale et transversale, ou/et des butées de limitation en translation selon une direction perpendiculaire aux deux précédentes. Ces moyens de limitation de course peuvent être intégrés, faire partie d'une construction monobloc, ou/et être rapportés. Les masses comportent, avantageusement, des moyens de butée agencés pour coopérer avec des moyens de butée complémentaire que comportent les traverses 40A, 40B, pour limiter le déplacement des lames flexibles élastiques par rapport à ces traverses, en cas de chocs ou d'accélérations similaires.Each

Dans les variantes illustrées, les moyens moteurs 12 sont agencés pour entraîner le mobile 13 selon un mouvement de rotation, et le mobile 13 et les moyens d'entraînement et de guidage 14 sont agencés pour appliquer au moyen de commande 15 un effort essentiellement tangentiel par rapport à la rotation du mobile 13.In the variants shown, the motor means 12 are arranged to drive the mobile 13 in a rotational movement, and the mobile 13 and the drive and guide means 14 are arranged to apply to the control means 15 a substantially tangential force by relative to the rotation of the mobile 13.

Dans les différentes variantes décrites ici, de préférence les moyens de rappel élastique 6 des résonateurs primaires 10 comportent des lames flexibles, et les résonateurs primaires 10 et/ou la structure commune 2, ou/et le cadre 4, comportent des butées radiales et/ou angulaires et/ou axiales agencées pour limiter les déformations des lames flexibles et pour éviter les ruptures en cas de chocs ou de couple moteur trop élevé.In the various variants described here, preferably the elastic return means 6 of the primary resonators 10 comprise flexible blades, and the primary resonators 10 and / or the
Dans une réalisation avantageuse, l'oscillateur horloger 1 comporte une structure monolithique qui regroupe une structure commune 4 vers laquelle sont rappelées les masses inertielles 5 par leurs moyens de rappel élastique 6, le moyen de commande 15 et ses articulations avec les moyens de transmission 16, et les moyens de transmission 16 avec leurs articulations aux masses inertielles 5.In an advantageous embodiment, the
Avantageusement, cette structure monolithique comporte encore les butées.Advantageously, this monolithic structure further comprises the stops.
De préférence, l'orientation des moyens de rappel élastique 6 des résonateurs primaires 10 est optimisée de manière à ce que les erreurs de marche dues à la gravité s'annule entre les résonateurs primaires 10.Preferably, the orientation of the elastic return means 6 of the primary resonators 10 is optimized so that the operating errors due to the gravity vanish between the primary resonators 10.
Dans une variante non illustrée, les moyens de rappel élastique 6 des résonateurs primaires 10 sont des pivots virtuels à lames croisées.In a variant that is not illustrated, the elastic return means 6 of the primary resonators 10 are virtual cross-blade pivots.
Dans une variante particulière de l'oscillateur horloger 1 selon invention, les résonateurs primaires 10 sont isochrones.In a particular variant of the
Les avantages de l'invention sont nombreux :
- une roue à rainure, contrairement à une liaison élastique sur une manivelle, n'ajoute pas de force de rappel parasite aux résonateurs lorsque l'amplitude change. Il s'ensuit un meilleur isochronisme ;
- l'utilisation de résonateurs rotatifs dont le centre de rotation est confondu avec le centre de masse évite que le centre de masse se déplace dans le champ de gravité, et, partant, évite que la période soit affectée par un changement d'orientation de la montre. Le même argument explique que notre système est moins affecté par des chocs en translations.
- de préférence, les résonateurs sont tous identiques et montés en parallèle. Les mouvements de l'un ne risquent donc pas de parasiter l'inertie de l'autre, contrairement aux montages en série ;
- l'utilisation de deux résonateurs, ou davantage, complètement distincts, c'est-à-dire avec une masse inertielle propre à chaque résonateur primaire ou élémentaire, permet d'optimiser l'isochronisme des résonateurs séparément, et de jouer sur leur orientation pour que les erreurs dues aux positions et les réactions à l'encastrement s'annulent. Cela est un grand avantage pour obtenir un oscillateur indépendant des positions de la montre, et ayant un facteur de qualité très élevé.
- la conception permet une fabrication très simple de la version intégrée ;
- l'invention permet des réalisations dans la plus pure tradition horlogère puisqu'on peut simplement utiliser deux ensembles balancier-spiral reliés à la roue d'échappement par des bielles très légères ou des lames flexibles.
- a grooved wheel, unlike an elastic link on a crank, does not add a parasitic biasing force to the resonators when the amplitude changes. It follows a better isochronism;
- the use of rotating resonators whose center of rotation coincides with the center of mass prevents the center of mass from moving in the gravitational field, and thus avoids that the period is affected by a change of orientation of the shows. The same argument explains that our system is less affected by shocks in translations.
- preferably, the resonators are all identical and connected in parallel. The movements of one are not likely to interfere with the inertia of the other, unlike series editing;
- the use of two or more completely distinct resonators, that is to say with an inertial mass specific to each primary or elementary resonator, makes it possible to optimize the isochronism of the resonators separately, and to play on their orientation for that positional errors and flush responses cancel each other out. This is a great advantage to obtain an oscillator independent of the positions of the watch, and having a very high quality factor.
- the design allows a very simple manufacture of the integrated version;
- the invention allows achievements in the purest watchmaking tradition since one can simply use two sprung balance assemblies connected to the escape wheel by very light rods or flexible blades.
