Abstract

L’invention concerne un résonateur rotatif comportant un mobile (3) soumis à un couple. Le résonateur comporte un premier oscillateur linéaire selon une première direction par rapport auquel oscille un deuxième oscillateur linéaire selon une deuxième direction orthogonale à la première direction, ce deuxième oscillateur comportant une deuxième masse porteuse d’une goupille (2) coopérant sans jeu avec une rainure (1) que comporte ce mobile (3), lequel comporte un patin frottant coulissant avec friction dans la rainure (1), et dans lequel patin frottant pivote cette goupille (2).The invention relates to a rotary resonator comprising a mobile (3) subjected to a torque. The resonator comprises a first linear oscillator in a first direction relative to which oscillates a second linear oscillator in a second direction orthogonal to the first direction, this second oscillator comprising a second mass carrying a pin (2) cooperating without play with a groove (1) that comprises the mobile (3), which comprises a sliding pad frictionally sliding in the groove (1), and wherein the friction pad pivots the pin (2).

Description

Description [0001] L’invention concerne, tel que visible sur la fig. 1, un résonateur 10 de type rotatif issu de la mise en série de deux oscillateurs 01 et 02 à guidage flexible comportant chacun une masse M1, M2, celle M1 du premier oscillateur 01 étant suspendue par des premières lames flexibles L1 à une structure fixe P telle qu’une platine. Le premier oscillateur 01 oscille essentiellement selon une première direction linéaire Y. La première masse mobile M1 de ce premier oscillateur 01 sert d’ancrage aux deuxièmes lames flexibles L2 d’un deuxième oscillateur 02, qui oscille essentiellement selon une deuxième direction linéaire X, perpendiculaire à la première direction linéaire Y. La deuxième masse mobile M2 du deuxième oscillateur 02 comporte une goupille 2, qui coopère avec une rainure 1 que porte un mobile 3 soumis à un couple, typiquement une roue d’échappement.Description [0001] The invention relates, as visible in FIG. 1, a resonator 10 of rotary type from the series connection of two oscillators 01 and 02 with flexible guide each having a mass M1, M2, the M1 of the first oscillator 01 being suspended by first flexible blades L1 to a fixed structure P such as a platinum. The first oscillator O1 oscillates essentially in a first linear direction Y. The first mobile mass M1 of this first oscillator O1 serves to anchor the second flexible blades L2 of a second oscillator O2, which oscillates essentially in a second linear direction X, perpendicular at the first linear direction Y. The second mobile mass M2 of the second oscillator O2 comprises a pin 2, which cooperates with a groove 1 which carries a mobile 3 subjected to a torque, typically an escape wheel.

[0002] Les forces de rappel ne sont pas exactement proportionnelles aux déplacements, car les guidages flexibles L1, L2, utilisés dans un tel résonateur sont très courts, ce qui entraîne une non-linéarité de la force du ressort en fonction du déplacement, ce qui introduit un défaut d’isochronisme.The restoring forces are not exactly proportional to the displacements, because the flexible guides L1, L2, used in such a resonator are very short, resulting in a non-linearity of the spring force as a function of displacement, which introduces a defect of isochronism.

[0003] De plus, si les deux oscillateurs 01 et 02 ne sont pas bien synchronisés, il s’ensuit un mouvement elliptique de la goupille 2 entraînée par la rainure 1 qui tourne avec le mobile 3.In addition, if the two oscillators 01 and 02 are not well synchronized, it follows an elliptical movement of the pin 2 driven by the groove 1 which rotates with the mobile 3.

[0004] Le risque est que ce mouvement elliptique prenne une excentricité nulle, et se transforme en simple va-et-vient linéaire, ce qui perturberait fortement le système. Pour rendre le système isochrone, on agence de façon particulière la rainure 1 qui sert de guidage à la goupille 2 fixée sur la deuxième masse M2 du deuxième oscillateur 02.The risk is that this elliptical movement takes a zero eccentricity, and is transformed into a simple back and forth linear, which would greatly disrupt the system. In order to make the isochronous system, the groove 1 which serves as a guide for the pin 2 fixed on the second mass M2 of the second oscillator 02 is arranged in a particular way.

[0005] Selon l’invention, on équipe cette rainure 1 d’un patin frottant 4, tel que visible sur la fig. 2. On crée deux frottements entre la goupille 2 et la rainure 1: - le premier frottement entre la goupille 2 et le patin frottant 4, notamment un patin prismatique de profil complémentaire à celui de la rainure 1 et coulissant dans cette rainure. Ce premier frottement est avantageusement minimisé, et surtout rendu constant, par un roulement à bille 6, la goupille 2 porte ainsi la cage intérieure 61 de ce roulement 6; - le deuxième frottement entre le patin frottant 4 et la rainure 1, dont la fonction est d’atténuer le mouvement elliptique de la goupille pour tendre vers un mouvement circulaire.According to the invention, this groove 1 is equipped with a friction pad 4, as shown in FIG. 2. Two friction is created between the pin 2 and the groove 1: the first friction between the pin 2 and the friction pad 4, in particular a prismatic pad of profile complementary to that of the groove 1 and sliding in this groove. This first friction is advantageously minimized, and especially made constant, by a ball bearing 6, the pin 2 thus carries the inner race 61 of the bearing 6; - The second friction between the friction pad 4 and the groove 1, whose function is to attenuate the elliptical movement of the pin to tend to a circular motion.

[0006] La cage extérieure 62 du roulement 6 est avantageusement montée dans le patin frottant 4, lequel coulisse avec friction dans la rainure 1 radiale du mobile 3. Ce patin frottant 4 permet de favoriser un déphasage de 90° entre les deux oscillateurs 01 et 02, et ainsi d’éviter que la trajectoire collapse sur une ligne.The outer race 62 of the bearing 6 is advantageously mounted in the friction pad 4, which slides with friction in the radial groove 1 of the mobile 3. This friction pad 4 allows to promote a phase shift of 90 ° between the two oscillators 01 and 02, and thus prevent the trajectory collapse on a line.

[0007] Ainsi l’invention concerne un tel résonateur 10 équipé d’un tel mobile 3 d’application d’un couple à ce résonateur 10 comportant un premier oscillateur 01 linéaire selon une première direction Y par rapport auquel oscille un deuxième oscillateur 02 linéaire selon une deuxième direction X orthogonale à ladite direction Y, ce deuxième oscillateur 02 comportant une deuxième masse M2 porteuse d’une goupille 2 pivotante dans un patin frottant 4 lequel coulisse à friction dans la rainure 1.Thus the invention relates to such a resonator 10 equipped with such a mobile 3 to apply a torque to the resonator 10 having a first linear oscillator 01 in a first direction Y relative to which oscillates a second linear oscillator 02 in a second direction X orthogonal to said direction Y, this second oscillator 02 having a second mass M2 carrying a pin 2 pivoting in a friction pad 4 which slides frictionally in the groove 1.

[0008] L’invention concerne encore un mouvement équipé d’un tel résonateur, et une montre équipée d’un tel mouvement.The invention also relates to a movement equipped with such a resonator, and a watch equipped with such a movement.
