Description

Domaine de l'inventionField of the invention

L'invention concerne un mécanisme régulateur rotatif d'horlogerie pour la régulation de la vitesse de rotation d'un mécanisme d'horlogerie soumis à l'action de moyens moteurs au travers de moyens de transmission.The invention relates to a rotary clockwork regulator mechanism for regulating the speed of rotation of a clockwork mechanism subjected to the action of motor means through transmission means.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant au moins un tel mécanisme régulateur rotatif.The invention also relates to a timepiece, in particular a watch, comprising at least one such rotary regulator mechanism.

L'invention concerne le domaine de la régulation de vitesse des mécanismes d'horlogerie.The invention relates to the field of speed regulation of clockwork mechanisms.

Arrière-plan de l'inventionBackground of the invention

Les microtechnologies ont favorisé l'émergence de résonateurs rotatifs de types nouveaux, destinés aux bases de temps de montres ou de pendules, et généralement entraînés par une glissière ou une coulisse. Néanmoins, pour l'emploi d'un oscillateur dans le garde-temps d'une montre, il faut satisfaire de nombreuses exigences, qui rendent leur emploi encore très délicat :

  • sensibilité aux positions,
  • sensibilité aux tolérances de fabrication ;
  • consommation d'énergie réduite ;
  • sensibilité au phasage des deux oscillations selon des axes orthogonaux ;
  • sensibilité aux frottements de la glissière d'entraînement.
Microtechnologies have favored the emergence of rotary resonators of new types, intended for the time bases of watches or clocks, and generally driven by a slide or a slide. However, for the use of an oscillator in the timepiece of a watch, many requirements must be met, which make their use still very delicate:
  • sensitivity to positions,
  • sensitivity to manufacturing tolerances;
  • reduced energy consumption;
  • sensitivity to the phasing of the two oscillations along orthogonal axes;
  • friction sensitivity of the drive slide.

Résumé de l'inventionSummary of the invention

On voit que l'emploi de liaisons à glissières n'est pas favorable pour des applications horlogères, qu'il s'agisse de bases de temps ou de fonctions annexes liées au fonctionnement des complications.It can be seen that the use of sliding links is not favorable for horological applications, whether they are time bases or ancillary functions linked to the operation of complications.

L'invention propose d'utiliser une bielle en remplacement de la glissière proposée dans l'art antérieur. Elle propose également de limiter l'utilisation d'un tel système de régulation à des fonctions moins exigeantes que le garde-temps d'une montre, soit des régulations de mécanismes annexes comme des sonneries, des passages quantièmes ou autres mouvements devant être régulés dans une montre sans que la régulation de fréquence nécessite une précision de l'ordre de quelques parties par million.The invention proposes to use a connecting rod to replace the slideway proposed in the prior art. It also proposes to limit the use of such a regulation system to functions less demanding than the timepiece of a watch, that is to say regulation of ancillary mechanisms such as bells, date passages or other movements that must be regulated in a watch without frequency regulation requiring a precision of the order of a few parts per million.

Il s'agit de proposer un mécanisme simple, entièrement mécanique.It is a question of proposing a simple, entirely mechanical mechanism.

A cet effet, l'invention concerne un mécanisme régulateur rotatif d'horlogerie pour la régulation de la vitesse de rotation d'un mécanisme d'horlogerie soumis à l'action de moyens moteurs au travers de moyens de transmission, selon la revendication 1.To this end, the invention relates to a rotary clockwork regulator mechanism for regulating the speed of rotation of a clockwork mechanism subjected to the action of motor means through transmission means, according to claim 1.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant au moins un tel mécanisme régulateur rotatif.The invention also relates to a timepiece, in particular a watch, comprising at least one such rotary regulator mechanism.

Description détaillée des modes de réalisation préférésDetailed description of the preferred embodiments

L'invention concerne un mécanisme régulateur rotatif 100 d'horlogerie pour la régulation de la vitesse de rotation d'un mécanisme d'horlogerie soumis à l'action de moyens moteurs 1 au travers de moyens de transmission 10.The invention relates to a rotary regulator mechanism 100 for clockwork for regulating the speed of rotation of a clockwork mechanism subjected to the action of motor means 1 through transmission means 10.

Selon l'invention, ce mécanisme régulateur rotatif 100 comporte un mécanisme oscillateur 20, qui est relié indirectement aux moyens de transmission 10 par des moyens de transformation de mouvement 30 comportant un système bielle-manivelle.According to the invention, this rotary regulator mechanism 100 comprises an oscillator mechanism 20, which is indirectly connected to the transmission means 10 by movement transformation means 30 comprising a connecting rod-crank system.

Ce mécanisme oscillateur 20 comporte classiquement au moins une masse inertielle 23, qui est soumise à l'action de moyens de rappel élastique 21.This oscillator mechanism 20 conventionally comprises at least one inertial mass 23, which is subjected to the action of elastic return means 21.

Le système bielle-manivelle comporte au moins une manivelle 31, qui est entraînée en rotation autour d'un axe de manivelle D1 par les moyens de transmission 10.The connecting rod-crank system comprises at least one crank 31, which is driven in rotation about a crank axis D1 by the transmission means 10.

Le système bielle-manivelle comporte encore au moins une bielle 33, qui est mobile angulairement par rapport à cette manivelle 31, dans un plan perpendiculaire à l'axe de manivelle D1, au niveau d'une première zone de contact 38 excentrique par rapport à l'axe de manivelle D1. Cette au moins une bielle 33 est mobile angulairement par rapport à une masse inertielle 23 dans un plan perpendiculaire à l'axe de manivelle D1, au niveau d'une deuxième zone de contact 39 qui est distante de la première zone de contact 38, pour assurer l'entretien du mécanisme oscillateur 20 par l'énergie fournie par les moyens moteurs 1, et pour assurer la régulation en vitesse d'un rouage 4 que comportent les moyens de transmission 10 par rapport à la fréquence du mécanisme oscillateur 20.The connecting rod-crank system also comprises at least one connecting rod 33, which is movable angularly relative to this crank 31, in a plane perpendicular to the crank axis D1, at the level of a first contact zone 38 which is eccentric with respect to the crank axis D1. This at least one connecting rod 33 is angularly movable with respect to an inertial mass 23 in a plane perpendicular to the crank axis D1, at the level of a second contact zone 39 which is distant from the first contact zone 38, for ensure the maintenance of the oscillator mechanism 20 by the energy supplied by the motor means 1, and to ensure the speed regulation of a gear train 4 that the transmission means 10 comprise with respect to the frequency of the oscillator mechanism 20.

Plus particulièrement, dans une variante articulée visible sur les figures 1 à 5, au moins une bielle 33 est articulée avec la manivelle 31 au niveau d'une première articulation définissant la première zone de contact 38, et est encore articulée avec une masse inertielle 23, au niveau d'une deuxième articulation définissant la deuxième zone de contact 39. La deuxième articulation.More particularly, in an articulated variant visible on the figures 1 to 5 , at least one connecting rod 33 is articulated with the crank 31 at the level of a first articulation defining the first contact zone 38, and is further articulated with an inertial mass 23, at the level of a second articulation defining the second contact zone 39. The second articulation.

Plus particulièrement, le système bielle-manivelle comporte un mobile récepteur 36, qui est solidaire de la manivelle 31, et qui est entraîné en rotation autour de l'axe de manivelle D1 par les moyens de transmission 10. La manivelle 31 comporte, au niveau de la première articulation, un maneton 32 ou un alésage, définissant un axe de maneton D2 autour duquel pivote librement, par un alésage 35 ou respectivement un tourillon qu'elle comporte, la bielle 33 qui comporte, à distance de l'axe de maneton D2, et au niveau de la deuxième articulation, un guidage 34 coopérant de façon complémentaire avec un guidage complémentaire 24 solidaire d'une masse inertielle 23.More particularly, the connecting rod-crank system comprises a receiving mobile 36, which is integral with the crank 31, and which is driven in rotation about the crank axis D1 by the transmission means 10. The crank 31 comprises, at the level of the first articulation, a crankpin 32 or a bore, defining a crankpin axis D2 around which pivots freely, by a bore 35 or respectively a journal that it comprises, the connecting rod 33 which comprises, at a distance from the crankpin axis D2, and at the level of the second articulation, a guide 34 cooperating in a complementary manner with a complementary guide 24 integral with an inertial mass 23.

Dans une variante, et tel que visible sur la figure 6, au moins une bielle 33 est solidaire d'au moins une lame flexible de bielle 330 mobile dans un plan perpendiculaire à l'axe de manivelle D1, et mobile angulairement, dans ce plan ou en projection sur ce plan, par rapport à au moins une lame flexible de manivelle 310 qui est solidaire de la au moins une manivelle 31 ou constituant cette manivelle 31.In a variant, and as visible on the figure 6 , at least one connecting rod 33 is integral with at least one flexible connecting rod blade 330 movable in a plane perpendicular to the crank axis D1, and movable angularly, in this plane or in projection on this plane, with respect to at least a flexible crank blade 310 which is integral with the at least one crank 31 or constituting this crank 31.

Plus particulièrement, au moins une lame flexible de bielle 330 et au moins une lame flexible de manivelle 310 sont agencées sur au moins deux niveaux parallèles.More particularly, at least one flexible connecting rod blade 330 and at least one flexible crank blade 310 are arranged on at least two parallel levels.

Plus particulièrement, au moins une bielle 33 et au moins une manivelle 31 constituent ensemble un unique composant monobloc incorporant des lames flexibles. Un tel agencement permet de réduire encore les frottements, en supprimant un pivotement.More particularly, at least one connecting rod 33 and at least one crank 31 together constitute a single one-piece component incorporating flexible blades. Such an arrangement makes it possible to further reduce friction, by eliminating pivoting.

Plus particulièrement, la masse inertielle 23 est agencée pour osciller autour d'un axe d'oscillateur D4 par rapport à une structure fixe 40, à laquelle la masse inertielle 23 est fixée par au moins une lame flexible 22 constituant les moyens de rappel élastique 21 du mécanisme oscillateur 20, et tendant à rappeler chaque masse inertielle 23 vers l'axe d'oscillateur D4.More particularly, the inertial mass 23 is arranged to oscillate about an oscillator axis D4 relative to a fixed structure 40, to which the inertial mass 23 is fixed by at least one flexible blade 22 constituting the elastic return means 21 of the oscillator mechanism 20, and tending to return each inertial mass 23 towards the oscillator axis D4.

L'extrémité distale de la masse inertielle 23 est agencée pour se mouvoir de façon sensiblement plane, dans un plan XY. L'axe d'oscillateur D4 est parallèle à l'axe de manivelle D1; plus particulièrement, ils sont confondus.The distal end of the inertial mass 23 is arranged to move in a substantially planar manner, in an XY plane. The oscillator axis D4 is parallel to the crank axis D1; more particularly, they are confused.

Ce mécanisme oscillateur 20 est plus particulièrement construit comme une masse inertielle 23 supportée par un fil ou un barre ronde en flexion. On comprend que la rotation de la masse inertielle 23 peut être décomposée en une flexion alternative sinusoïdale du fil selon l'axe X et une flexion alternative sinusoïdale selon l'axe Y, déphasées de 90°.This oscillator mechanism 20 is more particularly constructed as an inertial mass 23 supported by a wire or a bending round bar. It will be understood that the rotation of the inertial mass 23 can be broken down into an alternating sinusoidal bending of the wire along the X axis and an alternating sinusoidal bending along the Y axis, out of phase by 90 °.

Plus particulièrement, cette lame flexible 22 est unique.More particularly, this flexible blade 22 is unique.

Plus particulièrement, au moins une lame flexible 22 est constituée par un fil de flexion et/ou de torsion.More particularly, at least one flexible blade 22 consists of a bending and / or twisting wire.

Dans d'autres variantes non illustrées, le mécanisme oscillateur 20 comporte plusieurs lames flexibles ou fils flexibles, agencées ou agencés en faisceau, ou parallèles entre elles ou entre eux, ou autres.In other variants not shown, the oscillator mechanism 20 comprises several flexible blades or flexible wires, arranged or arranged in a bundle, or parallel to each other or to each other, or others.

Dans une variante, tel que visible sur la figure 8, la masse inertielle 23 est agencée pour osciller autour d'un axe d'oscillateur D4 par rapport à une structure fixe 40 à laquelle la masse inertielle 23 est suspendue par au moins un ensemble de lames élastiques 211 parallèles entre elles, par l'intermédiaire d'un support intermédiaire 41, cet au moins un ensemble de lames élastiques constituant les moyens de rappel élastique 21 du mécanisme oscillateur 20 et tendant à rappeler la au moins une masse inertielle 23 vers l'axe d'oscillateur D4.In a variant, as seen on the figure 8 , the inertial mass 23 is arranged to oscillate about an oscillator axis D4 relative to a fixed structure 40 from which the inertial mass 23 is suspended by at least one set of elastic blades 211 parallel to each other, via of an intermediate support 41, this at least one set of elastic blades constituting the elastic return means 21 of the oscillator mechanism 20 and tending to return the at least one inertial mass 23 towards the oscillator axis D4.

Dans une autre variante, tel que visible sur la figure 7, la masse inertielle 23 est agencée pour osciller autour d'un axe d'oscillateur D4 par rapport à une structure fixe 40 à laquelle la masse inertielle 23 est suspendue par des ressorts 212 constituant les moyens de rappel élastique 21 du mécanisme oscillateur 20 et tendant à rappeler la au moins une masse inertielle 23 vers l'axe d'oscillateur D4.In another variant, as seen on the figure 7 , the inertial mass 23 is arranged to oscillate about an oscillator axis D4 relative to a fixed structure 40 from which the inertial mass 23 is suspended by springs 212 constituting the elastic return means 21 of the oscillator mechanism 20 and tensioning in recalling the at least one inertial mass 23 towards the oscillator axis D4.

Plus particulièrement, ou bien le guidage 34 est un alésage et le guidage complémentaire 24 est une surface sphérique d'une rotule 25 solidaire d'une masse inertielle 23, ou bien le guidage 34 est une surface torique et le guidage complémentaire 24 est une surface cylindrique d'un tourillon 250 solidaire d'une masse inertielle 23.More particularly, either the guide 34 is a bore and the complementary guide 24 is a spherical surface of a ball 25 integral with an inertial mass 23, or else the guide 34 is a toric surface and the complementary guide 24 is a surface cylindrical with a journal 250 integral with an inertial mass 23.

L'entraînement doit être agencé pour éviter qu'un déphasage éventuel des deux axes (différent de 90°) ne réduise l'oscillation d'un des axes.The drive must be arranged to prevent a possible phase shift of the two axes (other than 90 °) from reducing the oscillation of one of the axes.

Dans une autre variante encore, et tel que visible sur la figure 9, la masse inertielle 23 est agencée pour osciller linéairement comme sur la figure, ou selon un degré de liberté unique le long d'une trajectoire imposée, et est soumise de part et d'autre à l'action de moyens de rappel élastique 21 qui sont fixés à une structure fixe que comporte le mécanisme régulateur rotatif 100.In yet another variant, and as seen on the figure 9 , the inertial mass 23 is arranged to oscillate linearly as in the figure, or according to a single degree of freedom along an imposed trajectory, and is subjected on both sides to the action of elastic return means 21 which are attached to a fixed structure that comprises the rotary regulator mechanism 100.

Dans un mécanisme à glissière de l'art antérieur, les mouvements de l'axe d'entraînement, dûs aux différences d'amplitudes liées à l'énergie dissipée et au éventuels déphasages des deux oscillations en X et Y, génèrent des frottements qui pénalisent la fonction.In a slide mechanism of the prior art, the movements of the drive shaft, due to the differences in amplitudes linked to the dissipated energy and to the possible phase shifts of the two oscillations in X and Y, generate friction which penalizes function.

L'invention remplace ainsi la glissière connue de l'art antérieur par un couple bielle-manivelle, qui remplit la condition de liberté de rayon jusqu'à un minimum et limite les frottements à deux pivotements.The invention thus replaces the slide known from the prior art by a connecting rod-crank pair, which fulfills the condition of freedom of radius to a minimum and limits the friction to two pivotings.

Les figures 3 à 5 montrent différentes positions relatives de la bielle 33 et de la manivelle 31 :

  1. A (figure 3) : Position amplitude minimum : garant de non déphasage si ≠90° ;
  2. B (figure 4): Position amplitude moyenne ;
  3. C (figure 5): Position amplitude grande.
The figures 3 to 5 show different relative positions of the connecting rod 33 and of the crank 31:
  1. AT ( figure 3 ): Minimum amplitude position: guarantee of no phase shift if ≠ 90 °;
  2. B ( figure 4 ): Average amplitude position;
  3. VS ( figure 5 ): Large amplitude position.

On constate comme défaut que l'angle de la bielle génère un offset angulaire, qui est fonction de l'amplitude, sur le rouage d'entrainement. Ce défaut, qui pourrait être pénalisant pour une base de temps devant garantir les 10 ppm, reste tout à fait admissible pour une régulation de mécanisme, comme une régulation de sonnerie, ou autre.As a defect, it is noted that the angle of the connecting rod generates an angular offset, which is a function of the amplitude, on the drive train. This defect, which could be penalizing for a time base having to guarantee the 10 ppm, remains entirely admissible for a mechanism regulation, such as a ringing regulation, or the like.

L'apport d'énergie est ici assuré par un rouage de finissage 4 et un barillet 2, de manière connue par l'homme du métier.The energy supply is here provided by a finishing gear 4 and a barrel 2, in a manner known to those skilled in the art.

L'invention concerne encore une pièce d'horlogerie 1000 comportant au moins un oscillateur principal 900 constituant une base de temps, et qui comporte au moins un tel mécanisme régulateur rotatif 100. Selon l'invention, chaque mécanisme oscillateur 20 est distinct de cet oscillateur principal 900.The invention also relates to a timepiece 1000 comprising at least one main oscillator 900 constituting a time base, and which comprises at least one such rotary regulator mechanism 100. According to the invention, each oscillator mechanism 20 is distinct from this oscillator. main 900.

Plus particulièrement, un tel mécanisme régulateur rotatif 100 est agencé pour réguler la vitesse de rotation d'un mécanisme d'horlogerie qui est un mécanisme de sonnerie.More particularly, such a rotary regulator mechanism 100 is arranged to regulate the speed of rotation of a clockwork mechanism which is a striking mechanism.

Plus particulièrement, un tel mécanisme régulateur rotatif 100 est agencé pour réguler la vitesse de rotation d'un mécanisme d'horlogerie qui est un mécanisme d'entraînement de quantième.More particularly, such a rotary regulator mechanism 100 is arranged to regulate the speed of rotation of a clockwork mechanism which is a date drive mechanism.
