Description

Domaine de l'inventionField of the invention

L'invention concerne un mouvement d'horlogerie pour une montre mécanique, comportant, agencés sur une platine, un mécanisme résonateur et un mécanisme d'entretien soumis au couple de moyens moteurs que comporte ledit mouvement.The invention relates to a watch movement for a mechanical watch, comprising, arranged on a plate, a resonator mechanism and a maintenance mechanism subjected to the pair of motor means that includes said movement.

L'invention concerne encore une montre mécanique comportant au moins un tel mouvement.The invention also relates to a mechanical watch comprising at least one such movement.

L'invention concerne le domaine des mécanismes résonateurs constituant les bases de temps des montres mécaniques.The invention relates to the field of resonator mechanisms constituting the time bases of mechanical watches.

Arrière-plan de l'inventionBackground of the invention

La plupart des montres mécaniques actuelles comportent un résonateur de type balancier-spiral, qui constitue la base de temps de la montre, et un mécanisme d'échappement, généralement à ancre suisse, lequel remplit deux fonctions principales:

  • l'entretien des va-et-vient du résonateur ;
  • le comptage de ces va-et-vient.
Most of the current mechanical watches include a sprung-balance resonator, which is the time base of the watch, and an escapement mechanism, usually Swiss-anchored, which has two main functions:
  • maintenance of the comings and goings of the resonator;
  • Counting these back and forth.

Le mécanisme d'échappement doit être robuste, résister aux chocs, et être conçu pour éviter de coincer le mouvement (renversement).The exhaust mechanism must be strong, shock-resistant, and designed to avoid pinching the movement (overturning).

Un résonateur mécanique combine au minimum un élément inertiel et un élément de rappel élastique. Dans le balancier-spiral, le spiral joue le rôle d'élément de rappel élastique pour l'élément inertiel que constitue le balancier.A mechanical resonator combines at least one inertial element and an elastic return element. In the spiral balance, the spiral acts as an elastic return element for the inertial element that constitutes the balance.

Le balancier est classiquement guidé en rotation par des pivots qui tournent dans des paliers lisses en rubis. Cela donne lieu à des frottements, et donc à des pertes d'énergie et des perturbations de marche, que l'on cherche à supprimer. Les pertes sont caractérisées par le facteur de qualité Q. On cherche à maximiser ce facteur Q.The balance is conventionally guided in rotation by pivots which rotate in smooth ruby bearings. This gives rise to friction, and therefore to energy losses and disturbances, which we seek to remove. The losses are characterized by the quality factor Q. We seek to maximize this Q factor.

L'échappement à ancre suisse a un rendement énergétique faible (environ 30%). Ce faible rendement provient du fait que les mouvements de l'échappement sont saccadés, qu'il y a des « chutes » (chemin perdus pour s'accommoder des erreurs d'usinage) et, aussi, du fait que plusieurs composants 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 (about 30%). This low performance comes from the fact that the movements of the exhaust are jerky, that there are "falls" (path lost to accommodate machining errors) and, also, that several components are transmitted their movement via inclined planes that rub against each other.

La demande de brevet EP2908189 au nom de ETA Manufacture Horlogère Suisse décrit un mécanisme de synchronisation de deux oscillateurs d'horlogerie avec un rouage, où un mécanisme régulateur d'horlogerie comporte, montés mobiles, au moins en pivotement par rapport à une platine, une roue d'échappement agencée pour recevoir un couple moteur via un rouage, et un premier oscillateur comportant une première structure rigide reliée à cette platine par des premiers moyens de rappel élastique. Ce mécanisme régulateur comporte un deuxième oscillateur, qui comporte une deuxième structure rigide, laquelle est reliée à la première structure rigide par des deuxièmes moyens de rappel élastique, et qui comporte des moyens de guidage agencés pour coopérer avec des moyens de guidage complémentaire que comporte la roue d'échappement, synchronisant le premier oscillateur et le deuxième oscillateur avec le rouage.The patent application EP2908189 in the name of ETA Manufacture Horlogère Suisse describes a synchronization mechanism of two clockwork oscillators with a gear train, where a watchmaking mechanism comprises, mounted mobile, at least pivotally relative to a plate, an arranged escape wheel to receive a motor torque via a train, and a first oscillator having a first rigid structure connected to this plate by first elastic return means. This regulating mechanism comprises a second oscillator, which comprises a second rigid structure, which is connected to the first rigid structure by second elastic return means, and which comprises guide means arranged to cooperate with complementary guide means that includes the escape wheel, synchronizing the first oscillator and the second oscillator with the wheel.

La demande de brevet EP3054358 au nom de ETA Manufacture Horlogère Suisse décrit un oscillateur horloger, qui comporte une structure et des résonateurs primaires distincts, déphasés temporellement et géométriquement, comportant chacun une masse rappelée vers la structure par un moyen de rappel élastique. Cet oscillateur horloger comporte des moyens de couplage pour l'interaction des résonateurs primaires, comportant des moyens moteurs pour entraîner en mouvement un mobile lequel comporte des moyens d'entraînement et de guidage agencés pour entraîner et guider un moyen de commande articulé avec des moyens de transmission chacun articulé, à distance du moyen de commande, avec une masse d'un résonateur primaire, et les résonateurs primaires et le mobile sont agencés de telle façon que les axes des articulations de deux quelconques des résonateurs primaires et l'axe d'articulation du moyen de commande ne sont jamais coplanaires.The patent application EP3054358 in the name of ETA Manufacture Horlogère Suisse describes a clock oscillator, which comprises a structure and separate primary resonators, temporally and geometrically out of phase, each comprising a mass biased towards the structure by an elastic return means. This clock oscillator comprises coupling means for the interaction of the primary resonators, comprising motor means for driving a mobile in motion which comprises driving and guiding means arranged to drive and guide an articulated control means with means for transmission each articulated, remote control means, with a mass of a primary resonator, and the primary resonators and the mobile are arranged such that the axes of the joints of any two of the primary resonators and the axis of articulation of the control means are never coplanar.

Résumé de l'inventionSummary of the invention

La présente invention a pour objectif de supprimer les saccades du mécanisme d'entretien d'un résonateur, notamment un mécanisme d'échappement, afin d'augmenter le rendement de ce mécanisme d'entretien.The present invention aims to eliminate the saccades of the maintenance mechanism of a resonator, including an exhaust mechanism, to increase the performance of this maintenance mechanism.

Pour atteindre cet objectif, on propose un mécanisme permettant des interactions continues, donc sans saccades, entre résonateur et mobile d'entretien, notamment une roue d'échappement. On doit, pour ce faire, concéder l'utilisation d'un deuxième degré de liberté du résonateur, le deuxième degré de liberté étant déphasé par rapport au premier.To achieve this goal, we propose a mechanism for continuous interactions, so without saccades, between resonator and mobile maintenance, including an escape wheel. To do this, we must concede the use of a second degree of freedom of the resonator, the second degree of freedom being out of phase with the first.

Ainsi, l'invention concerne un mouvement d'horlogerie selon la revendication 1.Thus, the invention relates to a watch movement according to claim 1.

L'invention concerne encore une montre mécanique comportant au moins un tel mouvement.The invention also relates to a mechanical watch comprising at least one such movement.

Dans la variante de la figure 3, la piste 82 est une piste intérieure de l'anneau rigide 8, lequel comporte, à l'intérieur et à distance du contour 82, un moyeu 83 qui définit avec la piste 82 une gorge 84 dans laquelle circule le maneton 72, la gorge 84 constituant une sécurité prévenant tout décrochement entre la manivelle 7 et le résonateur 100 en cas de choc, ou en cas de déphasage entre les deux degrés de liberté du résonateur 100.In the variant of the figure 3 , the track 82 is an inner track of the rigid ring 8, which has, inside and at a distance from the contour 82, a hub 83 which defines with the track 82 a groove 84 in which the crank pin 72 passes, the throat 84 constituting a security preventing any separation between the crank 7 and the resonator 100 in case of shock, or in the event of a phase shift between the two degrees of freedom of the resonator 100.

Plus particulièrement, la piste 82 et le moyeu 83 sont concentriques.More particularly, the track 82 and the hub 83 are concentric.

Dans le cas particulier de la figure 5, les deux degrés de liberté du mécanisme résonateur 100 sont des rotations autour du centre d'inertie CI d'un élément inertiel 2 du résonateur 100 comportant l'anneau 8.In the particular case of figure 5 , the two degrees of freedom of the resonator mechanism 100 are rotations around the center of inertia CI of an inertial element 2 of the resonator 100 comprising the ring 8.

Dans une variante particulière et avantageuse, la période d'oscillation du mécanisme résonateur 100 selon le premier degré de liberté DDL1 et la période d'oscillation du mécanisme résonateur 100 selon le second degré de liberté DDL2 sont sensiblement identiques. Plus particulièrement, ces périodes sont égales.In a particular and advantageous variant, the oscillation period of the resonator mechanism 100 according to the first degree of freedom DDL1 and the oscillation period of the resonator mechanism 100 according to the second degree of freedom DDL2 are substantially identical. More particularly, these periods are equal.

Dans une variante particulière non illustrée, le mécanisme résonateur 100 comporte un élément inertiel 2 comportant l'anneau 8, l'élément inertiel comportant des masselottes de réglage de l'inertie et du balourd.In a particular variant not shown, the resonator mechanism 100 comprises an inertial element 2 comprising the ring 8, the inertial element comprising flyweights for adjusting the inertia and unbalance.

Dans une variante particulière illustrée par la figure 7, le mécanisme résonateur 100 comporte deux éléments inertiels 2A , 2B, oscillant avec un déphasage temporel d'un quart de période, et chacun lié à l'anneau 8 de manière flexible, selon une direction perpendiculaire à celle autour de laquelle oscille le élément inertiel 2A, 2B considéré.In a particular variant illustrated by the figure 7 , the resonator mechanism 100 comprises two inertial elements 2A, 2B, oscillating with a quarter-time phase shift, and each linked to the ring 8 in a flexible manner, in a direction perpendicular to that around which the inertial element oscillates 2A, 2B considered.

Plus particulièrement, chaque élément inertiel 2A, 2B, est lié à la platine 1 au moyen d'un guidage flexible à lames croisées 31, 32, définissant un axe virtuel de rotation passant par le centre d'inertie CI de l'élément inertiel 2A, 2B, considéré.More particularly, each inertial element 2A, 2B is connected to the plate 1 by means of a flexible guide with crossed blades 31, 32, defining a virtual axis of rotation passing through the center of inertia CI of the inertial element 2A. , 2B, considered.

Dans une variante, le mécanisme résonateur 100 à deux degrés de liberté est à résonateur à guidages flexibles, comportant des lames flexibles agencées pour guider au moins un élément inertiel 2 du résonateur 100 et/ou l'anneau 8, et pour assurer le rappel élastique de cet élément inertiel 2 et/ou de cet anneau 8.In a variant, the resonator mechanism 100 with two degrees of freedom is a resonator with flexible guides, comprising flexible blades arranged to guide at least one inertial element 2 of the resonator 100 and / or the ring 8, and to provide the elastic return of this inertial element 2 and / or of this ring 8.

Dans une variante particulière, les lames flexibles sont en « élinvar ».In a particular variant, the flexible blades are "élinvar".

Dans une variante particulière, les lames flexibles sont en silicium oxydé afin de compenser les effets des températures.In a particular variant, the flexible blades are made of oxidized silicon in order to compensate for the effects of temperatures.

De façon avantageuse, et tel qu'illustré par les figures, les moyens de rappel élastique sont constitués par des guidages rotatifs flexibles dépourvus de pivot.Advantageously, and as illustrated by the figures, the elastic return means are constituted by flexible rotary guides without a pivot.

Dans une mise en oeuvre particulière de l'invention, les moyens de rappel élastique forment tous ensemble un composant monolithique.In a particular embodiment of the invention, the elastic return means together form a monolithic component.

Dans une mise en oeuvre particulière de l'invention, illustrée par les figures, les moyens de rappel élastique comportent des guidages flexibles à deux lames qui sont, soit croisées dans un même plan, soit des lames situées dans deux plans parallèles voisins et dont les projections se croisent dans un plan parallèle.In a particular embodiment of the invention, illustrated by the figures, the elastic return means comprise flexible guides with two blades which are either crossed in the same plane or blades located in two parallel parallel planes and whose projections intersect in a parallel plane.

Dans cette variante de guidage flexible à deux lames, le point de croisement réel ou en projection des deux lames est, avantageusement situé en un point situé entre 0.12 et 0.14 fois leur longueur, et ces lames forment entre elles un angle compris entre 60 et 80 degrés.In this variant of flexible guide with two blades, the actual or projection point of intersection of the two blades is advantageously located at a point between 0.12 and 0.14 times their length, and these blades form between them an angle of between 60 and 80 degrees.

Dans une variante illustrée à la figure 8, le mécanisme d'entretien 200 comporte des moyens d'entraînement 40, avec une lumière 42 agencée pour guider un galet 45. Ce galet 45 est agencé pour rouler sur une piste annulaire 250 que comporte le mobile inertiel 2, laquelle piste 250 constitue des moyens d'entraînement continu complémentaires 20. Le galet 45 imprime ainsi à l'élément inertiel un effort déporté, et un couple, qui, tend à imprimer à l'élément inertiel 2 un mouvement de précession, à la façon d'une pièce de monnaie ou d'une assiette mise en mouvement sur une surface plane par l'action d'un couple, ou encore d'un gyroscope ou d'une toupie. Le mécanisme d'entretien continu est alors constitué d'un anneau portant la piste annulaire 250, et solidaire de l'élément inertiel 2, entraîné en un mouvement de précession par la roue 4 à galet 45, soumise au couple des moyens moteurs 300, notamment d'au moins un barillet, la roue 4 tournant selon un axe perpendiculaire au plan défini par les axes de rotation des deux rotations flexibles.In a variant illustrated in figure 8 , the maintenance mechanism 200 comprises drive means 40, with a slot 42 arranged to guide a roller 45. This roller 45 is arranged to roll on an annular track 250 that includes the inertial mobile 2, which track 250 constitutes Complementary continuous drive means 20. The roller 45 thus imparts to the inertial element a deported force, and a torque, which tends to impart to the inertial element 2 a precession movement, in the manner of a workpiece. currency or a plate set in motion on a flat surface by the action of a couple, or a gyroscope or a spinning top. The continuous maintenance mechanism then consists of a ring bearing the annular track 250, and integral with the inertial element 2, driven in a precession movement by the wheel 4 to roller 45, subjected to the torque of the motor means 300, in particular at least one barrel, the wheel 4 rotating along an axis perpendicular to the plane defined by the axes of rotation of the two flexible rotations.

L'invention concerne encore une pièce d'horlogerie, notamment une montre mécanique 1000, comportant un tel mouvement 500.The invention also concerns a timepiece, in particular a mechanical watch 1000, comprising such a movement 500.

La figure 10 montre des résultats expérimentaux, sous forme de diagrammes présentant, en fonction du couple en abscisse, en microN.m : A l'amplitude en mm; PR la puissance réglante en mW, M la marche en s/jour, et R le rendement en %. On voit que le système fonctionne sur une immense plage de couple et que le rendement est proche de 98%. Le retard dû à ce système d'échappement dépend assez fortement du couple, ce qui peut être compensé par une non-linéarité des ressorts de rappel.The figure 10 shows experimental results, in the form of diagrams showing, as a function of the abscissa torque, in microN.m: A the amplitude in mm; PR the regulating power in mW, M walking in s / day, and R the yield in%. We see that the system operates over an immense range of torque and that the efficiency is close to 98%. The delay due to this exhaust system depends quite strongly on the torque, which can be compensated for by non-linearity of the return springs.

En somme, la présente invention présente des avantages particuliers :

  • la suppression des frottements de pivots du résonateur, grâce à leur remplacement par des guidages flexibles, permettant d'augmenter le facteur de qualité ;
  • la suppression des saccades à l'entretien, grâce à l'entretien continu, permettant d'augmenter le rendement d'entretien, notamment le rendement d'échappement quand le mécanisme d'entretien est un mécanisme d'échappement.
In sum, the present invention has particular advantages:
  • the suppression of the friction of the resonator pivots, thanks to their replacement by flexible guides, making it possible to increase the quality factor;
  • the elimination of maintenance saccades, through continuous maintenance, to increase the maintenance performance, including the exhaust performance when the maintenance mechanism is an escape mechanism.
