L'invention concerne le domaine des mécanismes de régulation pour l'horlogerie mécanique.The invention relates to the field of regulation mechanisms for mechanical watchmaking.
La technologie des oscillateurs et résonateurs d'horlogerie a beaucoup évolué avec l'apparition des techniques de réalisation de composants en silicium ou matériaux de caractéristiques similaires, qui ont permis l'avènement de guidages flexibles, en particulier à lames, définissant des pivots virtuels, et permettant de s'affranchir des pivots traditionnels, consommateurs d'énergie, sujets à l'usure, et nécessitant des lubrifications adéquates.The technology of clockwork oscillators and resonators has evolved a great deal with the appearance of techniques for producing components in silicon or materials with similar characteristics, which have enabled the advent of flexible guides, in particular with blades, defining virtual pivots, and allowing to overcome the traditional pivots, energy consumers, subject to wear, and requiring adequate lubrication.
De nombreux paramètres restent néanmoins à améliorer : les faibles amplitudes d'oscillation, la transmission d'efforts importants, la sensibilité aux chocs, et, de façon générale la sensibilité aux perturbations du porté, en particulier en ce qui concerne la rotation.Many parameters still need to be improved: the low amplitudes of oscillation, the transmission of significant forces, the sensitivity to shocks, and, in general, the sensitivity to disturbances when carried, in particular with regard to rotation.

L'invention concerne un mécanisme régulateur d'horlogerie 300, comportant une pluralité de résonateurs primaires 100, 200. Ce mécanisme régulateur 300 est un mécanisme à résonateurs articulés.The invention relates to a
L'invention est applicable en particulier, mais non limitativement, aux résonateurs sur pivots flexibles à faible course, pour montre mécanique, lesquels sont usuellement très sensibles aux perturbations lors du porté, et notamment très sensibles aux accélérations angulaires, notamment en rotation.The invention is applicable in particular, but not restrictively, to resonators on flexible pivots with short travel, for mechanical watches, which are usually very sensitive to disturbances during wearing, and in particular very sensitive to angular accelerations, in particular in rotation.
Les figures n'illustrent, de façon non limitative, que la variante avec deux tels résonateurs primaires 100, 200, et l'homme du métier saura sans peine extrapoler les caractéristiques de l'invention à un nombre supérieur de résonateurs.The figures illustrate, in a nonlimiting manner, only the variant with two such
Ces résonateurs primaires 100, 200, comportent chacun au moins une masse inertielle 102, 202, qui est mobile de façon pivotante par rapport à une structure fixe 101, 201, à laquelle la masse inertielle 102, 202, est suspendue par une pluralité de lames flexibles 103, 203. Ces lames flexibles définissent, de façon connue, un axe de pivotement virtuel autour duquel pivote la masse inertielle concernée, avec un écart très faible, de quelques micromètres ou dizaines de micromètres, notamment inférieur à 30 micromètres, entre la position de l'axe instantané de pivotement et l'axe virtuel théorique imposé par la forme et le positionnement des lames flexibles.These
Selon l'invention, ce mécanisme régulateur 300 comporte des moyens mécaniques de synchronisation d'au moins deux tels résonateurs primaires 100, 200. Ces moyens mécaniques de synchronisation comportent une liaison articulée entre deux masses inertielles 102, 202, que comportent les deux résonateurs primaires 100, 200.According to the invention, this regulating
Cette liaison articulée est agencée pour autoriser, en régime normal, le pivotement des deux masses inertielles 102, 202, selon des sens de rotation opposés, et avec des valeurs d'angles de rotation voisines. Et la liaison articulée est agencée pour interdire, lors d'un choc, le pivotement des deux masses inertielles 102, 202, selon le même sens de rotation.This articulated connection is arranged to allow, in normal operation, the pivoting of the two
Dans une réalisation particulière, cette liaison articulée est avec jeu.In a particular embodiment, this articulated connection is with play.
Plus particulièrement et non limitativement, et tel que visible sur les
Ainsi, tel que visible sur les
En cas de choc rotatif, le premier résonateur 100 et le deuxième résonateur 200 tendent à tourner dans le même sens, et la liaison articulée les en empêche, ce qui garantit un fonctionnement correct de l'échappement avec lequel coopère au moins un des deux résonateurs. Il n'y a pas d'arrêt intempestif comme ce serait le cas pour un résonateur unique sur pivot flexible à faible course.In the event of a rotary shock, the
L'entretien des résonateurs peut être effectué de différentes façons.The maintenance of the resonators can be carried out in different ways.
La
Plus particulièrement, cet oscillateur comporte une ancre élargie 401, telle que décrite dans la demande
Un bras 110, que comporte le résonateur primaire 100, 200, avec lequel le mécanisme d'échappement 400 est agencé pour coopérer, le premier résonateur 100 dans le cas de la
Un deuxième moyen d'entretenir les résonateurs, qui ne fait pas partie de l'invention, est d'utiliser un échappement à repos frottant, qui agit alternativement sur le premier résonateur 200 et le deuxième résonateur 200. Ainsi, tel que visible sur les
Les avantages de cette variante sont nombreux.The advantages of this variant are numerous.
En effet, l'énergie est distribuée de façon égale sur les deux résonateurs. Quand les deux résonateurs primaires 100, 200, ont le même réglage en fréquence et en équilibrage, la liaison articulée est en contact mécanique seulement en cas de choc: la goupille 104 et la fente 204 ne se touchent jamais, sauf en cas de perturbation externe. Ceci permet de minimiser la perturbation de la marche due au frottement entre la goupille 104 et la fente 204.Indeed, the energy is distributed equally on the two resonators. When the two
De préférence, la géométrie des palettes 121, 221, est la même pour les deux résonateurs, ce qui permet d'optimiser les chemins de frottement. Par rapport à un échappement à repos frottant traditionnel, qui a les deux palettes sur le même mobile, la configuration avec une palette par mobile, permet de choisir la géométrie de palette avec le même rendement, sans être obligé d'utiliser des palettes courbes telles que connues de l'échappement Graham. Les
Ainsi, plus particulièrement, le mécanisme d'échappement 400 à repos frottant comporte une roue d'échappement 420 en silicium et/ou dioxyde de silicium, et les palettes 121; 221 sont en rubis de façon à minimiser les forces de contact entre les dents 421 de la roue d'échappement 420 et les palettes 121, 221.Thus, more particularly, the
Selon l'invention,un troisième moyen d'entretenir les résonateurs consiste à utiliser un mécanisme régulateur 300 articulé, qui comporte un oscillateur lequel comporte un mécanisme d'échappement 400 libre à double impulsion tangentielle directe, tel que visible sur la
Ce mécanisme est comparable à un échappement coaxial, dans lequel l'impulsion directe de l'ancre est remplacée ici par une impulsion directe sur la masse inertielle du deuxième résonateur.This mechanism is comparable to a coaxial escapement, in which the direct impulse of the anchor is replaced here by a direct impulse on the inertial mass of the second resonator.
Plus particulièrement, dans une variante illustrée par la
Selon ce troisième moyen, le mécanisme d'échappement 400 est libre à double impulsion tangentielle directe.According to this third means, the
En effet, il est libre car le résonateur est libre pendant une partie de son oscillation, ce qui est favorable d'un point de vue chronométrique.Indeed, it is free because the resonator is free during part of its oscillation, which is favorable from a chronometric point of view.
Il est à double impulsion, car une impulsion se produit à chaque alternance de l'oscillation.It is double-pulse, because a pulse occurs with each alternation of the oscillation.
Il est à impulsion tangentielle, car le contact qui produit l'impulsion se produit sensiblement sur la ligne qui relie le centre d'inertie de la masse inertielle considérée au centre de la roue d'échappement (par opposition à l'impulsion frottante d'un échappement à ancre suisse traditionnel).It is tangential impulse, because the contact which produces the impulse occurs substantially on the line which connects the center of inertia of the inertial mass considered to the center of the escape wheel (as opposed to the friction impulse of a traditional Swiss lever escapement).
Il est à impulsion directe car l'impulsion est donnée directement de la roue au résonateur, sans nécessairement passer par une ancre.It is a direct impulse because the impulse is given directly from the wheel to the resonator, without necessarily going through an anchor.
On comprend que cette double impulsion directe n'est possible que parce que les deux masses inertielles pivotent selon des sens opposés. Ainsi, la roue d'échappement, qui tourne toujours dans le même sens, peut pousser l'une des masses inertielles lors de la première alternance, et l'autre lors de la deuxième alternance.It is understood that this direct double impulse is only possible because the two inertial masses pivot in opposite directions. Thus, the escape wheel, which always turns in the same direction, can push one of the inertial masses during the first alternation, and the other during the second alternation.
