Description

Domaine techniqueTechnical area

La présente invention concerne un mouvement d'horlogerie, notamment pour une pièce d'horlogerie mécanique. Plus particulièrement, elle concerne un mouvement d'horlogerie comprenant :

  • une source d'énergie mécanique,
  • un premier organe réglant et un premier échappement reliés par un premier rouage à ladite source d'énergie, le premier rouage, le premier échappement et le premier organe réglant définissant un premier ensemble,
  • un deuxième organe réglant et un deuxième échappement reliés par un deuxième rouage à ladite source d'énergie, le deuxième rouage, le deuxième échappement et le deuxième organe réglant définissant un deuxième ensemble, et
  • un engrenage différentiel agencé pour assurer une liaison cinématique entre le premier ensemble et la source d'énergie d'une part et entre le deuxième ensemble et la source d'énergie d'autre part.
The present invention relates to a watch movement, in particular for a mechanical timepiece. More particularly, it relates to a watch movement comprising:
  • a source of mechanical energy,
  • a first regulating member and a first escapement connected by a first wheel to said energy source, the first wheel, the first escapement and the first regulating member defining a first assembly,
  • a second regulating member and a second escapement connected by a second wheel to said energy source, the second wheel, the second escapement and the second regulating member defining a second set, and
  • a differential gear arranged to provide a kinematic connection between the first set and the energy source on the one hand and between the second set and the energy source on the other.

La présente invention concerne également une pièce d'horlogerie comprenant un tel mouvement.The present invention also relates to a timepiece comprising such a movement.

Etat de la techniqueState of the art

Un mouvement similaire est notamment décrit dans le brevet CH 698622 . Ce type de mouvement comprenant deux organes réglants alimentés par l'engrenage différentiel décrit dans le brevet CH 698622 ou tout autre engrenage différentiel connu de l'art antérieur présente certains effets indésirables liés à l'utilisation d'un tel engrenage différentiel. Notamment, lors d'une impulsion simultanée sur les deux chaines cinématiques comprenant l'une le premier ensemble et l'autre le deuxième ensemble, l'énergie sera tout d'abord fournie à la chaine cinématique qui nécessite le moins d'énergie. C'est seulement après cela que la deuxième chaine recevra de l'énergie. Cela a pour conséquence que l'énergie servant à entretenir l'organe réglant de la deuxième chaine sera perdue. En effet, comme l'impulsion sur l'organe réglant aura déjà été faite, l'ancre sera donc déjà en phase de repos. Cela entraine une perte de l'amplitude du deuxième balancier et une augmentation de celle du premier balancier, ce qui est néfaste à la marche de la pièce d'horlogerie.A similar movement is described in particular in the patent CH 698622 . This type of movement comprising two regulating members powered by the differential gear described in the patent CH 698622 or any other differential gear known from the prior art has certain undesirable effects related to the use of such a differential gear. In particular, during a simultaneous pulse on the two kinematic chains comprising one the first set and the other set second, the energy will first be provided to the kinematic chain that requires the least energy. Only after that will the second channel receive energy. This has the consequence that the energy used to maintain the regulating organ of the second chain will be lost. Indeed, as the impulse on the organ regulation has already been made, the anchor will be already in the rest phase. This causes a loss of the amplitude of the second pendulum and an increase of that of the first pendulum, which is detrimental to the running of the timepiece.

Un but de la présente invention est donc de pallier cet inconvénient, en proposant un mouvement d'horlogerie permettant de fournir immédiatement à chacun des deux organes réglants l'énergie qui lui est nécessaire sans perturber l'autre organe réglant.An object of the present invention is therefore to overcome this disadvantage, by providing a clockwork to provide immediately to each of the two regulating organs energy that is necessary without disturbing the other regulating organ.

  • the figure 2 is an isometric view of the differential gear and spring members used in the invention, and
  • the figure 3 represents a sectional view of the figure 2 .

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

En référence à la figure 1, le mouvement d'horlogerie selon l'invention comprend notamment

  • une source d'énergie mécanique 1, tel qu'un barillet,
  • un premier organe réglant 2 et un premier échappement 4, comprenant une première roue d'échappement 5 et une première ancre 6, reliés par un premier rouage 8 à ladite source d'énergie 1, le premier rouage 8, le premier échappement 4 et le premier organe réglant 2 définissant un premier ensemble,
  • un deuxième organe réglant 10 et un deuxième échappement 12 comprenant une deuxième roue d'échappement 13 et une deuxième ancre 14, reliés par un deuxième rouage 16 à ladite source d'énergie 1, le deuxième rouage 16, le deuxième échappement 12 et le deuxième organe réglant 10 définissant un deuxième ensemble,
  • un engrenage différentiel 18 agencé pour assurer une liaison cinématique entre le premier ensemble et la source d'énergie 1 d'une part et entre le deuxième ensemble et la source d'énergie 1 d'autre part.
With reference to the figure 1 , the watch movement according to the invention comprises in particular
  • a source of mechanical energy 1, such as a cylinder,
  • a first regulating member 2 and a first escapement 4, comprising a first escape wheel 5 and a first anchor 6, connected by a first wheel 8 to said energy source 1, the first wheel 8, the first escapement 4 and the first regulating member 2 defining a first set,
  • a second regulating member 10 and a second escapement 12 comprising a second escape wheel 13 and a second anchor 14, connected by a second wheel 16 to said energy source 1, the second wheel 16, the second exhaust 12 and the second regulating member 10 defining a second set,
  • a differential gear 18 arranged to ensure a kinematic connection between the first set and the energy source 1 on the one hand and between the second set and the energy source 1 on the other hand.

Dans la variante représentée ici, les organes réglants 2 et 10 sont des balanciers simples, mais il est bien évident qu'ils peuvent être également des tourbillons ou des carrousels. De même, les premier et deuxième échappements représentés sont à ancre suisse mais ils pourraient être d'un autre type, tel que des échappements à détente ou d'autres types d'échappement connus.In the variant shown here, the regulating members 2 and 10 are simple pendulums, but it is obvious that they can also be whirlpools or carousels. Similarly, the first and second exhausts shown are Swiss-anchored but they could be of another type, such as escapements or relaxation other known exhaust types.

En référence plus particulièrement aux figures 2 et 3, les éléments composant l'engrenage différentiel sont montés pivotant autour d'un arbre 20 solidaire du bâti du mouvement.With particular reference to figures 2 and 3 , the components of the differential gear are pivotally mounted around a shaft 20 integral with the movement frame.

L'engrenage différentiel 18 comprend une roue d'entrée 22 montée pivotante autour de l'arbre 20 et présentant une denture extérieure engrenant avec un renvoi 24 engrenant lui-même avec la source d'énergie 1. Il est bien évident que le mécanisme peut comprendre d'autres mobiles que le renvoi 24 entre l'engrenage différentiel 18 et la source d'énergie 1.The differential gear 18 comprises an input wheel 22 pivotally mounted around the shaft 20 and having an external toothing meshing with a gear 24 meshing itself with the energy source 1. It is obvious that the mechanism can comprise other mobiles than the return 24 between the differential gear 18 and the energy source 1.

La roue d'entrée 22 est solidaire d'un porte-satellite 26 qui comporte des arbres 28 perpendiculaires à l'arbre 20 et sur chacun desquels est monté pivotant un pignon-satellite 30. Dans la variante représentée, les pignons-satellites 30 sont à denture conique.The input wheel 22 is integral with a planet carrier 26 which comprises shafts 28 perpendicular to the shaft 20 and on each of which is pivotally mounted a planet gear 30. In the variant shown, the planet gears 30 are with conical teeth.

L'engrenage différentiel 18 comprend également une première roue de transmission 32 et une deuxième roue de transmission 34, respectivement montées pivotantes autour de l'arbre 20 au moyen d'un canon 33 et 35 respectivement. Chacune des première et deuxième roues de transmission 32, 34 présente une denture conique disposée de part et d'autre des pignons-satellites 30. Les dentures coniques des première et deuxième roues de transmission 32, 34 sont choisies de sorte qu'elles engrènent avec les dentures coniques des pignons-satellites 30.The differential gear 18 also includes a first transmission wheel 32 and a second transmission wheel 34, respectively pivotally mounted about the shaft 20 by means of a barrel 33 and 35 respectively. Each of the first and second transmission wheels 32, 34 has a conical toothing arranged on either side of the planet gears 30. The conical teeth of the first and second transmission wheels 32, 34 are chosen so that they mesh with the conical teeth of the planet gears 30.

Les première et deuxième roues de transmission 32, 34 représentées ici sont sous la forme de roue-cloche, mais il est bien évident que toute roue de transmission d'un différentiel plat peut convenir. De même la forme des dentures des pignons-satellites et des dentures des roues de transmission est adaptée à la construction du différentiel. Notamment, les dentures peuvent être droites.The first and second transmission wheels 32, 34 shown here are in the form of a bell-wheel, but it is obvious that any transmission wheel of a flat differential may be suitable. Likewise, the shape of the gears of the planet gears and the teeth of the transmission wheels are adapted to the construction of the differential. In particular, the teeth can be straight.

L'engrenage différentiel 18 comprend également une première roue de sortie 36 et une deuxième roue de sortie 38, respectivement montées libres en rotation autour de l'arbre 20, et disposées à l'extérieur des première et deuxième roues de transmission 32, 34 respectivement.The differential gear 18 also comprises a first output wheel 36 and a second output wheel 38, respectively rotatably mounted around the shaft 20, and disposed outside the first and second transmission wheels 32, 34 respectively .

La première roue de sortie 36 présente une denture extérieure engrenant avec le premier rouage 8 et la deuxième roue de sortie 38 présente une denture extérieure engrenant avec le deuxième rouage 16.The first output wheel 36 has an external toothing meshing with the first gear 8 and the second output wheel 38 has an external toothing meshing with the second gear 16.

Une première goupille 40 est chassée dans la première roue de transmission 32 et insérée avec du jeu dans un trou prévu dans la première roue de sortie 36. De même, une deuxième goupille 42 est chassée dans la deuxième roue de transmission 34 et insérée avec du jeu dans un trou prévu dans la deuxième roue de sortie 38. Le rôle de ces goupilles 40, 42 sera décrit ci-après.A first pin 40 is driven into the first transmission wheel 32 and inserted with play into a hole provided in the first output wheel 36. Similarly, a second pin 42 is driven into the second transmission wheel 34 and inserted with play in a hole provided in the second output wheel 38. The role of these pins 40, 42 will be described below.

Conformément à l'invention, le mouvement comporte en outre :

  • un premier organe ressort ou élastique 44 prévu entre l'engrenage différentiel 18 et le premier échappement 4 et armé pour exercer un couple sur la première roue de sortie 36,
  • un deuxième organe ressort ou élastique 46 prévu entre l'engrenage différentiel 18 et le deuxième échappement 12 et armé pour exercer un couple sur la deuxième roue de sortie 38.
According to the invention, the movement further comprises:
  • a first spring or elastic member 44 provided between the differential gear 18 and the first escapement 4 and cocked to exert a torque on the first output wheel 36,
  • a second spring or elastic member 46 provided between the differential gear 18 and the second escapement 12 and cocked to exert a torque on the second output wheel 38.

Plus précisément, le premier organe ressort 44 est placé à l'extérieur de la première roue de sortie 36, à l'opposé de la première roue de transmission 32, concentriquement à l'arbre 20. Il présente une première extrémité 48 solidaire de la première roue de sortie 36 au moyen d'une goupille 50 et une seconde extrémité 52 solidaire du canon 33 de la première roue de transmission 32.More specifically, the first spring member 44 is placed outside the first output wheel 36, opposite the first transmission wheel 32, concentrically to the shaft 20. It has a first end 48 integral with the first output wheel 36 by means of a pin 50 and a second end 52 secured to the barrel 33 of the first transmission wheel 32.

De même, le deuxième organe ressort 46 est placé à l'extérieur de la deuxième roue de sortie 38, à l'opposé de la deuxième roue de transmission 34, concentriquement à l'arbre 20. Il présente une première extrémité 54 solidaire de la deuxième roue de sortie 38 au moyen d'une goupille 56 et une seconde extrémité 58 solidaire du canon 35 de la deuxième roue de transmission 34.Similarly, the second spring member 46 is placed outside the second output wheel 38, opposite the second transmission wheel 34, concentrically to the shaft 20. It has a first end 54 integral with the second output wheel 38 by means of a pin 56 and a second end 58 secured to the barrel 35 of the second transmission wheel 34.

Un pré-armage des premier et deuxième organes ressorts peut être prévu lors de construction du mouvement.Pre-arming of the first and second spring members may be provided during movement construction.

Dans une autre variante de construction non représentée, le premier organe ressort 44 peut être placé à l'intérieur de la première roue de sortie 36, du même côté que la première roue de transmission 32, et le deuxième organe ressort 46 peut être placé à l'intérieur de la deuxième roue de sortie 38, du même côté que la deuxième roue de transmission 34.In another variant of construction not shown, the first spring member 44 can be placed inside the first output wheel 36, the same side as the first transmission wheel 32, and the second spring member 46 can be placed inside the second output wheel 38 on the same side as the second transmission wheel 34.

Dans la variante représentée, les organes ressorts 44 et 46 sont des ressorts spiraux.In the variant shown, the spring members 44 and 46 are spiral springs.

Il est bien évident que d'autres variantes de réalisation peuvent être prévues, telles que par exemple remplacer le spiral et la roue de sortie associée par une roue intégrant un élément élastique. Les organes ressorts ou éléments élastiques peuvent être de tout type de forme (boudin, spiral, lame-ressort, etc.), et de toute matière, la forme et la matière étant choisies pour que lesdits organes ressorts ou éléments élastiques permettent d'emmagasiner et de restituer de l'énergie.It is obvious that other embodiments may be provided, such as for example replace the spiral and the output wheel associated with a wheel incorporating an elastic member. The spring members or elastic members may be of any type of shape (coil, spiral, leaf spring, etc.), and any material, the shape and the material being chosen so that said springs or elastic members can store and to restore energy.

Le fonctionnement du mouvement selon l'invention est le suivant :The operation of the movement according to the invention is as follows:

Lors du fonctionnement, la force motrice arrivant de la source d'énergie 1 entre dans l'engrenage différentiel 18 par le renvoi 24, la roue d'entrée 22 et le porte-satellite 26 qui porte les pignons-satellites 30.During operation, the driving force arriving from the energy source 1 enters the differential gear 18 by the gearbox 24, the input wheel 22 and the planet carrier 26 which carries the planet gears 30.

Lorsque les première et deuxième ancres 6 et 14 libèrent les roues d'échappement 5 et 13 respectivement, les roues de sortie associées 36 et 38 respectivement transmettent un couple à leur rouage associé 8 et 16 respectivement. Comme les organes ressorts 44 et 46 sont pré-armés sur leur roue de sortie associée 36 et 38 respectivement, ces dernières vont tourner dès qu'elles en auront la possibilité. Les roues de sortie 36 et 38 vont se mettre en mouvement avant les roues de transmission 32 et 34. En effet, les roues de sortie 36 et 38 sont plus proches des échappements 4 et 12 que les roues de transmission 32 et 34. Ainsi, le chemin de force à parcourir étant moins important pour parvenir aux roues de sortie 36 et 38, ces dernières ont un temps de réaction plus rapide que les roues de transmission 32 et 34.When the first and second anchors 6 and 14 release the escape wheels 5 and 13 respectively, the associated output wheels 36 and 38 respectively transmit a torque to their associated gear train 8 and 16 respectively. As the spring members 44 and 46 are pre-armed on their associated output wheel 36 and 38 respectively, the latter will turn as soon as they have the possibility. The output wheels 36 and 38 will set in motion before the transmission wheels 32 and 34. In fact, the output wheels 36 and 38 are closer to the exhausts 4 and 12 than the transmission wheels 32 and 34. Thus, the force path to be traveled is less important to reach the output wheels 36 and 38, they have a reaction time faster than the transmission wheels 32 and 34.

Ce mécanisme permet de transmettre aux roues de sortie 36 et 38 des forces qui proviennent exclusivement de leurs organes ressorts respectifs 44 et 46. Cette transmission se déroule également lorsque les impulsions des organes réglants 2 et 10 sont simultanées.This mechanism makes it possible to transmit to the output wheels 36 and 38 forces that come exclusively from their respective spring members 44 and 46. This transmission also occurs when the pulses of the regulating members 2 and 10 are simultaneous.

Ainsi, chaque organe réglant 2 et 10 reçoit instantanément l'énergie qui lui est nécessaire sans perturber l'autre. De ce fait, tous les effets indésirables rencontrés avec les engrenages différentiels connus de l'art antérieur sont supprimés, y compris lorsque les impulsions sont simultanées.Thus, each regulating organ 2 and 10 instantaneously receives the energy it needs without disturbing the other. As a result, all the undesirable effects encountered with the differential gears known from the prior art are eliminated, even when the pulses are simultaneous.

Afin de permettre le réarmage de leur organe ressort associé 44, 46, les première et deuxième roues de transmission 32, 34, entrainées par la source d'énergie 1, vont rattraper leurs décalages respectifs par rapport aux roues de sortie associées 36, 38. Ainsi, le couple initial des organes ressorts 44 et 46 sera rétabli. De plus, les goupilles 40, 42 servent de butée aux roues de transmission 32 et 34 dans les roues de sortie 36, 38 lorsqu'elles rattrapent leurs décalages, afin de toujours réarmer l'organe ressort associé 44, 46 avec un même couple.In order to allow the rearming of their associated spring member 44, 46, the first and second transmission wheels 32, 34, driven by the energy source 1, will catch their respective offsets relative to the associated output wheels 36, 38. Thus, the initial torque of the spring members 44 and 46 will be restored. In addition, the pins 40, 42 serve as a stop for the transmission wheels 32 and 34 in the output wheels 36, 38 when they catch their offsets, to always rearm the associated spring member 44, 46 with the same torque.

Le cycle peut alors reprendre.The cycle can then resume.

Il est bien évident que la présente invention n'est pas limitée à l'exemple de réalisation décrit. Notamment, le mouvement d'horlogerie peut comprendre plusieurs engrenages différentiels qui se suivent, placés entre un engrenage différentiel principal, situé le plus proche de la source d'énergie, et l'échappement du premier et/ou du deuxième ensemble. Dans ce cas, le premier organe ressort prévu entre l'engrenage différentiel principal et le premier échappement peut être plus spécifiquement disposé entre la sortie de l'engrenage différentiel principal et l'entrée de l'élément coopérant suivant, à savoir un deuxième engrenage différentiel. De même, le deuxième organe ressort prévu entre l'engrenage différentiel principal et le deuxième échappement peut être plus spécifiquement disposé entre la sortie de l'engrenage différentiel principal et l'entrée de l'élément coopérant suivant, à savoir un troisième engrenage différentiel.It is obvious that the present invention is not limited to the embodiment described. In particular, the watch movement may comprise several successive differential gears, placed between a main differential gear, located closest to the energy source, and the exhaust of the first and / or second set. In this case, the first spring member provided between the main differential gear and the first escapement may be more specifically disposed between the output of the main differential gear and the input of the next cooperating element, namely a second differential gear. . Similarly, the second spring member provided between the main differential gear and the second escapement may be more specifically disposed between the output of the main differential gear and the input of the next cooperating element, namely a third differential gear.
