Definitions
- the present invention relates to an isochronous, self-starting mechanical horological regulator, the energy consumption of which is low.
- EP1736838 which describes a mechanical oscillator and a grasshopper escapement.
- the escapement is made up of two elastic blades, each blade of which has one end linked to the balance and a free end working with an escape wheel.
- the balance is pushed by one of its blades to beyond neutral. It is then the balance which pushes on the other blade so that the first can release. If the pendulum does not have enough momentum to provide clearance, then the system becomes blocked. This principle cannot therefore be self-starting.
- the aim of the present invention is to provide an isochronous, self-starting mechanical horological regulator whose energy consumption is low.
- the horological mechanical regulator of the invention comprises an oscillator with flexible guidance and a double-detent escapement, the oscillator comprising a balance linked to an elastic suspension arranged to guide and return the balance in a plane of oscillation.
- the escapement comprises an escape wheel and an anchor integrated into the balance and having two arms arranged to alternately receive impulses from the escape wheel.
- the escapement further comprises two detents alternately blocking the escape wheel between two pulses and cooperating with the arms of the anchor to release the escape wheel before each pulse, without direct cooperation between the anchor and the wheel. exhaust. Then the escape wheel transmits its impulse directly to the arms of the anchor.
- the main advantage of the invention compared to a traditional watch regulator composed of a spring-balance type oscillator and a Swiss lever escapement is that its power consumption is much lower, typically at least three times lower. . Therefore, the first advantage resulting from this low consumption is that the power reserve of the watch will be longer. This implies that the time of use of the watch before it stops will be at least three times longer. Second advantage linked to this low energy consumption: the barrel spring will take at least three times longer to discharge; its torque will therefore vary less during a given period of time which means, for a given isochronism of the regulator, that the rate variation over this period of time will also be smaller. The characteristics of the system which make it possible to minimize this energy consumption will be detailed below.
- each trigger consists of a flexible blade having a fixed end and a free end, these free ends cooperating on the one hand with an arm of the anchor and on the other hand with the wheel. exhaust.
- detents are therefore clearly distanced from conventional detents as described in EP3059641 .
- a conventional trigger comprises a rigid structure provided with a pivot, a rigid stopper and a flexible blade.
- flexible blade any prismatic beam (typically of rectangular section) whose thickness is at least 10 times smaller than the length and at least 2 times smaller than the width.
- the section can change dimension along the blade and the path along the length of this blade can be straight or curved.
- each trigger comprises a rest plane which cooperates with the teeth of the escape wheel to block the latter during the rest phase of the escapement while allowing the balance to move. '' oscillate without contact with the escape wheel.
- each trigger comprises a release plane which cooperates with the arms of the anchor to release the escape wheel before each pulse.
- the ends of the arms of the anchor comprise impulse planes cooperating with the beak of each tooth of the escape wheel so as to transmit energy from the escape wheel to the balance.
- the end of the anchor impulse plane then becomes the impulse nozzle and is pushed by the back of one of the teeth of the escape wheel.
- the rest planes of the detents are arranged relative to the anchor arms so that at the end of the release (achieved by the anchor) of one or the other of the detents , the tooth of the escape wheel in contact with the rest plane of said trigger transits directly on the impulse plane of the anchor arms without falling.
- a fall is a vacuum spinning of the escape wheel, often necessary as a transition between two exhaust phases to ensure that the system cannot jam but is also a significant energy loss of any exhaust.
- a drop is not necessary between the release and the impulse because the escape wheel comprises only a single toothing on a single level.
- the resting planes of the detents, the anchor impulse planes and the toothing of the escape wheel are then all located on the same work plane.
- the losses of inertial energy are due to the fact that it is necessary, at each impulse, to considerably accelerate the escape wheel so that it catches up with the balance and transmits its torque to it, this kinetic energy is then lost when the escape wheel strikes the rest plane of the detents.
- This loss of inertial energy can become considerably high compared to other types of loss when using a high frequency oscillator such as a flexible guided oscillator. It is therefore crucial to minimize the inertia of the escape wheel for an escapement operating with this particular type of oscillator.
- each of the two pulse planes receives a pulse from the escape wheel.
- the impulse planes of the arms of the anchor have a convex shape such that, when the escape wheel transmits its energy to the balance, the escape wheel is driven essentially by a uniformly accelerated movement.
- the utility of the shape of the pulse planes will be described later.
- the regulator comprises a fixed base comprising two rigid stops each corresponding respectively to one of the detents, the two rigid stops being arranged to give a preload torque of its respective detent against the corresponding stop.
- At least one of the detents comprises an end rigidly linked to an arm cooperating with an adjustment table, this linked end being opposite to said free end of the flexible detent; the position of this adjustment table can be modified relative to the fixed base in order to change the orientation of the flexible trigger relative to its rigid stop, which makes it possible to modify the preload torque of the flexible trigger which is resting against its rigid stopper.
- At least one of the detents cooperates with a stiffening member arranged to modify the active length of the flexible blade of said detent.
- the anchor comprises a beak cooperating with a tooth of the escape wheel such that this tooth of the escape wheel acts as a plane of rest in the case where one of the detents n fail to block the escape wheel.
- the elastic suspension of the oscillator preferably includes at least two flexible pivot blades.
- the balance, the anchor and the detents are typically made of silicon and shaped for DRIE technologies and the inertial body of the balance is obtained by assembling a dense material ring and a silicon ring.
- the silicon could be replaced by another material such as silica glass which would be shaped by a typically femtosecond laser and possibly followed by chemical attack.
- the invention also relates to a clockwork movement or a wristwatch comprising a regulator according to the present invention.
- the mechanical watch regulator comprises an oscillator with flexible guidance and a double-trigger escapement, the oscillator comprising a balance 1 kinematically linked to an elastic suspension 2a, 2b arranged to guide and recall the balance 1 in a plane of oscillation.
- the escapement has an escape wheel 3 and an anchor 4 integrated into the balance 1 and having two arms 5, 6 arranged to alternately receive pulses from the escape wheel 3.
- the escapement also comprises two detents 7, 8 alternately blocking the escape wheel 3 between two pulses and cooperating with the arm 5, 6 of the anchor to release the escape wheel 3 before each impulse, without direct cooperation between the anchor and the escape wheel.
- the flexible guided oscillator is composed of an inertial body 1a linked to the elastic suspension 2a, 2b providing on the one hand the guiding function of the inertial body 1a in the desired path and on the other hand the elastic return function.
- Each trigger 7, 8 consists of a flexible blade having a fixed end 7a, 8a and a free end 7b, 8b, this free end cooperating on the one hand with an arm 5, 6 of the anchor and on the other hand with escape wheel 3.
- the isochronism defect of the oscillator suspension 2a, 2b is corrected by the detents 7, 8.
- a single detent 7, 8 is supported on the balance 1 during the additional arc and the two detents 7, 8 are in contact with the balance 1 during the release of the escape wheel and the impulse. Since the detents 7, 8 are flexible, the rigidity of the regulator varies during the oscillation. The detents 7, 8 therefore tend to reduce the average rigidity of the large amplitude oscillator. This compensates for the fact that the flexible oscillator suspension tends to be stiffer on average at large amplitude.
- each trigger 7b, 8b has a rest plane 7c, 8c (see figures 2 , 3 and 4 ) which cooperates with the teeth of the escape wheel 3 to block the latter during the rest phase of the escape while allowing the balance 1 to oscillate without contact with the escape wheel 3.
- each trigger 7, 8 comprises a release plane which cooperates with the arms 5, 6 of the anchor to release the escape wheel 3 before each impulse.
- the ends of the arms 5, 6 of the anchor comprise impulse planes 5a, 6a cooperating with the teeth of the escape wheel 3 so as to transmit the energy of the escape wheel 3 to the balance wheel 1.
- the end of the impulse plane 5c, 6c becomes the impulse nozzle and is pushed by the impulse plane of the tooth of the escape wheel 3c .
- the impulse planes 5a, 6a are advantageously arranged in contiguous with the rest planes of the detents 7c, 8c at the time of disengagement, so as to avoid a fall between the disengagement and the impulse; If it were not avoided, this fall would cause a loss of energy, therefore a lower efficiency of the escapement and therefore a lower amplitude of the balance 1.
- This effect can be obtained by the fact that the escape wheel 3 does not have a single toothing on a single level and that the escape wheel 3 is located on the same working plane P as the rest planes 7c, 8c of the detents and the impulse planes of the anchor 5a, 6a.
- each of the two pulse planes 5a, 6a of the anchor arms receives a pulse from the escape wheel 3.
- These pulse planes 5a, 6a have a convex shape such that, when the escape wheel 3 transmits its energy to the balance 1, the escape wheel 3 is driven essentially by a uniformly accelerated movement.
- the pulse planes 5a, 6a are said to be touch, that is to say they guarantee at least the brushing of the nose of the escape wheel 3a against one of the pulse planes 5a, 6a during the pulse phase. This ensures a continuous transmission of the energy from the escape wheel 3 to the balance 1.
- This characteristic is important for the escapements cooperating with an oscillator with flexible guide because the latter have the particularity of having a high frequency, typically 10. at 20 Hz, and a low amplitude, typically 5 to 20 degrees.
- the impulse phase is short and the balance 1, for a given amplitude, moves quickly.
- the escape wheel 3 before the impulse is stationary while the balance 1 is close to its maximum speed.
- the touch profile implies a variable transmission ratio between the escape wheel 3 and the anchor 4.
- the torque applied to the anchor 4 then increases during the pulse so as to compensate for the increase in torque.
- return torque of the elastic suspension 2a, 2b of the oscillator So even when the oscillator is at when stopped, the torque of the escape wheel 3 is sufficient to complete the impulse, which allows the system to self-start.
- the regulator comprises a fixed base 9 comprising two rigid stops 10a, 10b each interacting respectively with one of the detents 7, 8; each of these rigid stops is arranged to apply a preload torque to its respective trigger.
- the preload torque of at least one of the detents is adjustable and makes it possible to correct the isochronism defect of the clock regulator.
- the rigid stops 10a, 10b (see figure 7 ) and the preload torque make it possible to ensure the positioning of the detents 7, 8 during rest and to secure their positioning in the event of external shocks.
- the orientation of the trigger 8 is adjustable and makes it possible to adjust the isochronism defect of the clock regulator.
- the trigger 8 has one end 8a rigidly linked to an arm 13 cooperating with an adjustment table 11. This linked end 8a is opposite the free end 8b of the flexible trigger 8; the position of this adjustment table 11 can be changed relative to the fixed base 9 in order to change the orientation of the flexible trigger 8 relative to its rigid stop 10b, thus modifying the preload torque of the flexible trigger 8 pressed against the corresponding rigid stop 10b. It is clear that this mechanism can also be used to achieve fine tuning of the frequency of the system.
- the trigger 8 could cooperate with a stiffening member 14 arranged to modify the active length of the flexible blade of the trigger.
- each arm of the anchor 4 comprises a beak 5b, 6b cooperating with a tooth of the escape wheel 3 such that part 3b of this tooth of the escape wheel 3 acts as a rest plane in substitution detents 7, 8 in the event that, for example following an impact, one of the latter fails to block the escape wheel 3.
- the elastic suspension 2a, 2b of the flexible pivot oscillator has two blades but it could include more and the topology chosen (here of the Wittrick type according to EP2911012 ) to represent this oscillator is given only as an example and is in no way limiting.
- Another advantage of the present regulator is that the isochronism defect of the double expansion escapement naturally compensates for the isochronism defect of the flexible pivot of the oscillator. This effect is obtained by the fact that, unlike conventional trigger escapements, there is always at least one trigger in contact with the balance.
- the isochronism defect of the escapement of the present invention is adjustable, which makes it possible to adapt to the oscillator defect which can vary from one oscillator to another due to the manufacturing and assembly inaccuracies of parts.

Description
La présente invention se rapporte à un régulateur horloger mécanique isochrone, auto-démarrant et dont la consommation énergétique est faible.The present invention relates to an isochronous, self-starting mechanical horological regulator, the energy consumption of which is low.

Le but de la présente invention est de proposer un régulateur horloger mécanique isochrone, auto-démarrant et dont la consommation énergétique est faible.The aim of the present invention is to provide an isochronous, self-starting mechanical horological regulator whose energy consumption is low.
Le régulateur mécanique horloger de l'invention comporte un oscillateur à guidage flexible et un échappement à double détente, l'oscillateur comportant un balancier lié à une suspension élastique agencée pour guider et rappeler le balancier dans un plan d'oscillation. L'échappement comporte une roue d'échappement et une ancre intégrée au balancier et ayant deux bras agencés pour recevoir alternativement des impulsions de la roue d'échappement. L'échappement comporte en outre deux détentes bloquant alternativement la roue d'échappement entre deux impulsions et coopérant avec les bras de l'ancre pour libérer la roue d'échappement avant chaque impulsion, sans coopération directe entre l'ancre et la roue d'échappement. Puis la roue d'échappement transmet son impulsion directement aux bras de l'ancre.The horological mechanical regulator of the invention comprises an oscillator with flexible guidance and a double-detent escapement, the oscillator comprising a balance linked to an elastic suspension arranged to guide and return the balance in a plane of oscillation. The escapement comprises an escape wheel and an anchor integrated into the balance and having two arms arranged to alternately receive impulses from the escape wheel. The escapement further comprises two detents alternately blocking the escape wheel between two pulses and cooperating with the arms of the anchor to release the escape wheel before each pulse, without direct cooperation between the anchor and the wheel. exhaust. Then the escape wheel transmits its impulse directly to the arms of the anchor.
L'avantage principal de l'invention par rapport à un régulateur horloger traditionnel composé d'un oscillateur de type balancier-spiral et d'un échappement à ancre suisse est que sa puissance consommée est beaucoup plus faible, typiquement au moins trois fois plus faible. De ce fait, le premier avantage résultant de cette faible consommation est que la réserve de marche de la montre sera plus longue. Cela implique que la durée d'utilisation de la montre avant qu'elle ne s'arrête sera au moins trois fois plus longue. Deuxième avantage lié à cette faible consommation d'énergie : le ressort de barillet mettra au moins trois fois plus de temps à se décharger ; son couple variera donc moins pendant un laps de temps donné ce qui signifie, pour un isochronisme donné du régulateur, que la variation de marche sur ce laps de temps sera également plus faible. Les caractéristiques du système qui permettent de minimiser cette consommation énergétique seront détaillées plus loin.The main advantage of the invention compared to a traditional watch regulator composed of a spring-balance type oscillator and a Swiss lever escapement is that its power consumption is much lower, typically at least three times lower. . Therefore, the first advantage resulting from this low consumption is that the power reserve of the watch will be longer. This implies that the time of use of the watch before it stops will be at least three times longer. Second advantage linked to this low energy consumption: the barrel spring will take at least three times longer to discharge; its torque will therefore vary less during a given period of time which means, for a given isochronism of the regulator, that the rate variation over this period of time will also be smaller. The characteristics of the system which make it possible to minimize this energy consumption will be detailed below.
Dans une forme d'exécution, chaque détente est constituée d'une lame flexible ayant une extrémité fixe et une extrémité libre, ces extrémités libres coopérant d'une part avec un bras de l'ancre et d'autre part avec la roue d'échappement. Ces détentes se distancient donc clairement des détentes classiques tel que décrite dans
On entend par lame flexible toute poutre prismatique (typiquement de section rectangulaire) dont l'épaisseur est au moins 10 fois plus faible que la longueur et au moins 2 fois plus faible que la largeur. La section peut changer de dimension le long de la lame et la trajectoire suivant la longueur de cette lame peut être droite ou courbée.By flexible blade is meant any prismatic beam (typically of rectangular section) whose thickness is at least 10 times smaller than the length and at least 2 times smaller than the width. The section can change dimension along the blade and the path along the length of this blade can be straight or curved.
Selon cette forme d'exécution, l'extrémité libre de chaque détente comporte un plan de repos qui coopère avec les dents de la roue d'échappement pour bloquer celle-ci durant la phase de repos de l'échappement tout en permettant au balancier d'osciller sans contact avec la roue d'échappement.According to this embodiment, the free end of each trigger comprises a rest plane which cooperates with the teeth of the escape wheel to block the latter during the rest phase of the escapement while allowing the balance to move. '' oscillate without contact with the escape wheel.
Toujours selon cette même forme d'exécution, l'extrémité libre de chaque détente comporte un plan de dégagement qui coopère avec les bras de l'ancre pour libérer la roue d'échappement avant chaque impulsion.Still according to this same embodiment, the free end of each trigger comprises a release plane which cooperates with the arms of the anchor to release the escape wheel before each pulse.
De préférence, les extrémités des bras de l'ancre comportent des plans d'impulsion coopérant avec le bec de chaque dent de la roue d'échappement de sorte à transmettre l'énergie de la roue d'échappement au balancier. A la fin de l'impulsion l'extrémité du plan d'impulsion de l'ancre devient alors le bec d'impulsion et est poussé par le dos de l'une des dents de la roue d'échappement. Cela constitue une configuration avantageuse mais il est clair que le bec d'impulsion pourrait se situer uniquement sur la roue d'échappement et le plan d'impulsion uniquement sur l'ancre ou inversement.Preferably, the ends of the arms of the anchor comprise impulse planes cooperating with the beak of each tooth of the escape wheel so as to transmit energy from the escape wheel to the balance. At the end of the impulse, the end of the anchor impulse plane then becomes the impulse nozzle and is pushed by the back of one of the teeth of the escape wheel. This constitutes an advantageous configuration, but it is clear that the impulse nozzle could be located only on the escape wheel and the impulse plane only on the anchor or vice versa.
Selon cette forme d'exécution préférentielle, les plans de repos des détentes sont disposés par rapport aux bras d'ancre de telle sorte qu'à la fin du dégagement (réalisé par l'ancre) de l'une ou l'autre des détentes, la dent de la roue d'échappement en contact avec le plan de repos de ladite détente transite directement sur le plan d'impulsion des bras d'ancre sans chuter. Une chute est une rotation dans le vide de la roue d'échappement, souvent nécessaire comme transition entre deux phases d'échappement pour s'assurer que le système ne puisse se bloquer mais constitue également une perte d'énergie significative de tout échappement. Dans cette forme d'exécution, une chute n'est pas nécessaire entre le dégagement et l'impulsion car la roue d'échappement ne comprend qu'une seule denture sur un seul niveau. Les plans de repos des détentes, les plans d'impulsion de l'ancre et la denture de la roue d'échappement se situent alors tous sur un même plan de travail. Néanmoins il pourrait être utile d'ajouter une chute entre la phase de dégagement et la phase d'impulsion pour éviter que les bras d'ancre génèrent un recul de la roue d'échappement avant la phase de dégagement en conséquence d'erreurs de positionnement à l'assemblage des pièces constituant l'échappement. Il est clair que le fonctionnement global du système resterait le même mais que la consommation énergétique pourrait être affectée. Par ailleurs, le fait que la roue d'échappement n'ait qu'un seul niveau et une seule denture constitue un avantage important du design car cela contribue également à réduire l'inertie de la roue d'échappement qui est un paramètre déterminant pour la consommation énergétique du régulateur. En effet, les pertes d'énergie inertielle sont dues au fait qu'il faille, à chaque impulsion, accélérer considérablement la roue d'échappement pour qu'elle rattrape le balancier et lui transmette son couple, cette énergie cinétique est ensuite perdue lorsque la roue d'échappement percute le plan de repos des détentes. Cette perte d'énergie inertielle peut devenir considérablement élevée au regard des autres types de perte lorsque l'on utilise un oscillateur à fréquence élevée tel qu'un oscillateur à guidage flexible. Il est donc crucial de minimiser l'inertie de la roue d'échappement pour un échappement fonctionnant avec ce type particulier d'oscillateur.According to this preferred embodiment, the rest planes of the detents are arranged relative to the anchor arms so that at the end of the release (achieved by the anchor) of one or the other of the detents , the tooth of the escape wheel in contact with the rest plane of said trigger transits directly on the impulse plane of the anchor arms without falling. A fall is a vacuum spinning of the escape wheel, often necessary as a transition between two exhaust phases to ensure that the system cannot jam but is also a significant energy loss of any exhaust. In this embodiment, a drop is not necessary between the release and the impulse because the escape wheel comprises only a single toothing on a single level. The resting planes of the detents, the anchor impulse planes and the toothing of the escape wheel are then all located on the same work plane. However, it could be useful to add a drop between the release phase and the impulse phase to prevent the anchor arms from causing the escape wheel to retreat before the release phase as a result of positioning errors. to the assembly of the parts constituting the exhaust. It is clear that the overall operation of the system would remain the same but that energy consumption could be affected. Furthermore, the fact that the escape wheel has only one level and only one toothing constitutes an important advantage of the design because it also contributes to reducing the inertia of the escape wheel which is a determining parameter for the energy consumption of the regulator. In fact, the losses of inertial energy are due to the fact that it is necessary, at each impulse, to considerably accelerate the escape wheel so that it catches up with the balance and transmits its torque to it, this kinetic energy is then lost when the escape wheel strikes the rest plane of the detents. This loss of inertial energy can become considerably high compared to other types of loss when using a high frequency oscillator such as a flexible guided oscillator. It is therefore crucial to minimize the inertia of the escape wheel for an escapement operating with this particular type of oscillator.
Selon cette exécution, à chaque période de l'oscillateur chacun des deux plans d'impulsion reçoit une impulsion de la roue d'échappement.According to this embodiment, at each period of the oscillator each of the two pulse planes receives a pulse from the escape wheel.
Selon cette exécution préférentielle, les plans d'impulsion des bras de l'ancre ont une forme bombée telle que, lorsque la roue d'échappement transmet son énergie au balancier, la roue d'échappement est animée essentiellement d'un mouvement uniformément accéléré. L'utilité de la forme des plans d'impulsion sera décrite plus loin.According to this preferred embodiment, the impulse planes of the arms of the anchor have a convex shape such that, when the escape wheel transmits its energy to the balance, the escape wheel is driven essentially by a uniformly accelerated movement. The utility of the shape of the pulse planes will be described later.
Dans une forme d'exécution, le régulateur comporte une base fixe comportant deux butées rigides correspondant chacune respectivement à une des détentes, les deux butées rigides étant agencées pour donner un couple de précharge de sa détente respective contre la butée correspondante.In one embodiment, the regulator comprises a fixed base comprising two rigid stops each corresponding respectively to one of the detents, the two rigid stops being arranged to give a preload torque of its respective detent against the corresponding stop.
Selon cette forme d'exécution, au moins une des détentes comporte une extrémité liée rigidement à un bras coopérant avec une table de réglage, cette extrémité liée étant opposée à ladite extrémité libre de la détente flexible ; la position de cette table de réglage est modifiable par rapport à la base fixe afin de changer l'orientation de la détente flexible par rapport à sa butée rigide, ce qui permet de modifier le couple de précharge de la détente flexible qui est en appui contre sa butée rigide.According to this embodiment, at least one of the detents comprises an end rigidly linked to an arm cooperating with an adjustment table, this linked end being opposite to said free end of the flexible detent; the position of this adjustment table can be modified relative to the fixed base in order to change the orientation of the flexible trigger relative to its rigid stop, which makes it possible to modify the preload torque of the flexible trigger which is resting against its rigid stopper.
Dans une autre forme d'exécution, au moins l'une des détentes coopère avec un organe de rigidification agencé pour modifier la longueur active de la lame flexible de ladite détente.In another embodiment, at least one of the detents cooperates with a stiffening member arranged to modify the active length of the flexible blade of said detent.
Dans une forme d'exécution, l'ancre comporte un bec coopérant avec une dent de la roue d'échappement de telle manière que cette dent de la roue d'échappement agit comme plan de repos dans le cas où l'une des détentes n'arrive pas à bloquer la roue d'échappement.In one embodiment, the anchor comprises a beak cooperating with a tooth of the escape wheel such that this tooth of the escape wheel acts as a plane of rest in the case where one of the detents n fail to block the escape wheel.
La suspension élastique de l'oscillateur comporte de préférence au moins deux lames de pivot flexibles.The elastic suspension of the oscillator preferably includes at least two flexible pivot blades.
Le balancier, l'ancre et les détentes sont réalisés typiquement en silicium et mise en forme pour les technologies DRIE et le corps inertiel du balancier est obtenu par l'assemblage d'un anneau en matériau dense et d'un anneau en silicium. Le silicium pourrait être remplacé par un autre matériau comme du verre de silice qui serait mis en forme par un laser typiquement femto-seconde et éventuellement suivit d'une attaque chimique.The balance, the anchor and the detents are typically made of silicon and shaped for DRIE technologies and the inertial body of the balance is obtained by assembling a dense material ring and a silicon ring. The silicon could be replaced by another material such as silica glass which would be shaped by a typically femtosecond laser and possibly followed by chemical attack.

Comme illustré aux
L'oscillateur à guidage flexible est composé d'un corps inertiel 1a lié à la suspension élastique 2a, 2b assurant d'une part la fonction de guidage du corps inertiel 1a dans la trajectoire voulue et d'autre part la fonction de rappel élastique.The flexible guided oscillator is composed of an inertial body 1a linked to the
Chaque détente 7, 8 est constituée d'une lame flexible ayant une extrémité fixe 7a, 8a et une extrémité libre 7b, 8b, cette extrémité libre coopérant d'une part avec un bras 5, 6 de l'ancre et d'autre part avec la roue d'échappement 3.Each
Le défaut d'isochronisme de la suspension 2a, 2b de l'oscillateur est corrigé par les détentes 7, 8. Une seule détente 7, 8 est en appui sur le balancier 1 pendant l'arc supplémentaire et les deux détentes 7, 8 sont en contact avec le balancier 1 durant le dégagement de la roue d'échappement et l'impulsion. Les détentes 7, 8 étant flexibles, la rigidité du régulateur varie durant l'oscillation. Les détentes 7, 8 ont donc tendance à diminuer la rigidité moyenne de l'oscillateur à grande amplitude. Cela compense le fait que la suspension flexible de l'oscillateur à tendance à être plus rigide en moyenne à grande amplitude.The isochronism defect of the
L'extrémité libre de chaque détente 7b, 8b comporte un plan de repos 7c, 8c (voir
L'extrémité libre de chaque détente 7, 8 comporte un plan de dégagement qui coopère avec les bras 5, 6 de l'ancre pour libérer la roue d'échappement 3 avant chaque impulsion.The free end of each
Comme illustré aux
Les plans d'impulsion 5a, 6a sont avantageusement disposés en contigüe avec les plans de repos des détentes 7c, 8c au moment du dégagement, de manière à éviter une chute entre le dégagement et l'impulsion ; Si elle n'était évitée, cette chute causerait une perte d'énergie, donc un rendement plus faible de l'échappement et donc une amplitude plus faible du balancier 1. Cet effet peut être obtenu par le fait que la roue d'échappement 3 ne comprend d'une seule denture sur un seul niveau et que la roue d'échappement 3 se situe sur le même plan P de travail que les plans de repos 7c, 8c des détentes et les plans d'impulsion de l'ancre 5a, 6a.The impulse planes 5a, 6a are advantageously arranged in contiguous with the rest planes of the
A chaque période de l'oscillateur, chacun des deux plans d'impulsions 5a, 6a des bras d'ancre reçoit une impulsion de la roue d'échappement 3. Ces plans d'impulsion 5a, 6a ont une forme bombée telle que, lorsque la roue d'échappement 3 transmet son énergie au balancier 1, la roue d'échappement 3 est animée essentiellement d'un mouvement uniformément accéléré. Autrement dit, les plans d'impulsion 5a, 6a sont dits à effleurement, c'est-à-dire qu'ils garantissent au moins l'effleurement du bec de la roue d'échappement 3a contre l'un des plans d'impulsion 5a, 6a durant la phase d'impulsion. Cela assure une transmission continue de l'énergie de la roue d'échappement 3 au balancier 1. Cette caractéristique est importante pour les échappements coopérant avec un oscillateur à guidage flexible car ces derniers ont la particularité d'avoir une fréquence élevée, typiquement de 10 à 20 Hz, et une faible amplitude, typiquement de 5 à 20 degrés. Dans ce contexte, la phase d'impulsion est brève et le balancier 1, pour une amplitude donnée, se déplace rapidement. De plus la roue d'échappement 3 avant l'impulsion est à l'arrêt alors que le balancier 1 est proche de sa vitesse maximum. Ainsi, grâce au plan d'impulsion à effleurement, la roue d'échappement 3 arrivera de toute manière à rattraper le balancier 1 et à lui transmettre son énergie et ce quel que soit l'amplitude du balancier 1, de l'arrêt jusqu'à son amplitude nominale. De plus, le profil à effleurement implique un rapport de transmission variable entre la roue d'échappement 3 et l'ancre 4. Le couple appliqué à l'ancre 4 augmente alors au cours de l'impulsion de sorte de compenser l'augmentation du couple de rappel de la suspension élastique 2a, 2b de l'oscillateur. Ainsi même lorsque l'oscillateur est à l'arrêt, le couple de la roue d'échappement 3 est suffisant pour finir l'impulsion, ce qui permet l'auto-démarrage du système. Le régulateur comporte une base fixe 9 comportant deux butées rigides 10a, 10b interagissant chacune respectivement avec une des détentes 7, 8 ; chacune de ces butées rigides est agencée pour appliquer un couple de précharge sur sa détente respective.At each period of the oscillator, each of the two
Les détentes 7, 8, lorsqu'elles ne sont pas en contact avec le balancier 1, reposent avec un couple de précharge contre des butées rigides 10a, 10b. Le couple de précharge d'au moins une des détentes est réglable et permet de corriger le défaut d'isochronisme du régulateur horloger. De plus, les butées rigides 10a, 10b (voir

Par ailleurs, il est également possible d'ajouter des plans de blocage sur le balancier 1. Ces plans de blocage, par exemple à la suite d'un choc, empêcheraient l'une ou l'autre des détentes de trop pivoter et de libérer la roue d'échappement. Ce blocage interviendrait donc uniquement lorsque la roue d'échappement 3 est en appui avec la détente 7, 8 en question.Furthermore, it is also possible to add locking planes on the balance 1. These locking planes, for example following a shock, would prevent one or the other of the detents from pivoting too much and releasing the escape wheel. This blocking would therefore occur only when the
Les
- La roue d'échappement 3 commence par être sur le repos de la détente d'entrée 7c (
figure 5 ), la détente d'entrée 7 est en appui sursa butée 10a et la détente desortie 8 est en appui sur le bras desortie 6 de l'ancre. - Le pivotement du balancier 1 provoque le dégagement de la détente d'entrée 7 par le bras d'entrée de l'ancre 5, ce qui libère la roue d'échappement 3 (
figure 6 ), la détente d'entrée 7 n'est alors plus en contactavec sa butée 10a et est emportée par le bras d'entrée de l'ancre 5. - La roue d'échappement 3 est maintenant libérée et pivote dans le sens horaire (
figure 7 ), le bec 3a de l'une des dents de la roue d'échappement est en contact avec le plan d'impulsion à effleurement d'entrée 5a et pousse l'ancre 4. - La roue d'échappement 3 poursuit ensuite son impulsion (
figure 8 ),le plan d'impulsion 3c de la dent poussant le bras d'entrée de l'ancre 5. - En fin d'impulsion, le bras d'ancre opposé dépose la détente sur sa butée.
- L'impulsion d'entrée est terminée (
figure 9 ), la roue d'échappement 3 chute dans le sens horaire et est bloquée par le plan derepos 8c de la détente de sortie. La détente desortie 8 est en appui contresa butée 10b et la détente d'entrée 7 est emportée par le bras d'entrée de l'ancre 5.
- The
escape wheel 3 begins by being at the rest of theinput trigger 7c (figure 5 ), theinput trigger 7 rests on itsstop 10a and theoutput trigger 8 rests on theoutlet arm 6 of the anchor. - The pivoting of the balance 1 causes the release of the
input trigger 7 by the input arm of theanchor 5, which releases the escape wheel 3 (figure 6 ), theinput trigger 7 is then no longer in contact with itsstop 10a and is carried by the input arm of theanchor 5. - The
escape wheel 3 is now released and rotates clockwise (figure 7 ), thenose 3a of one of the teeth of the escape wheel is in contact with the inputtouch impulse plane 5a and pushes the anchor 4. - The
escape wheel 3 then continues its impulse (figure 8 ), theimpulse plane 3c of the tooth pushing the input arm of theanchor 5. - At the end of the pulse, the opposite anchor arm places the trigger on its stop.
- The input pulse has ended (
figure 9 ), theescape wheel 3 drops clockwise and is blocked by therest plane 8c of the output trigger. Theoutput trigger 8 bears against itsstop 10b and theinput trigger 7 is carried by the input arm of theanchor 5.
L'alternance suivante se poursuit alors de manière équivalente avec la rotation du balancier 1 dans le sens antihoraire suivie du dégagement, de l'impulsion et de la chute de sortie.The following alternation then continues in an equivalent manner with the rotation of the balance 1 in the counterclockwise direction followed by the release, the impulse and the exit fall.
Dans l'exemple illustré, la suspension élastique 2a, 2b de l'oscillateur sur pivot flexible comporte deux lames mais elle pourrait en comporter davantage et la topologie choisie (ici de type Wittrick selon
Grâce au régulateur de la présente invention, la consommation énergétique peut être très faible, inférieure à 0.3 uW (typiquement 0.25 uW). Une si faible puissance consommée est liée principalement :
- à la faible amplitude du balancier requise pour pouvoir être isochrone et peu sensible à la gravité,
typiquement entre 8 et 16 degrés, - à l'absence de frottement dans le pivot flexible du balancier,
- au fait que l'impulsion est transmise directement de la roue d'échappement au balancier ce qui supprime toute perte d'énergie associée à un mobile intermédiaire entre la roue et le balancier,
- au fait que les détentes permettent de limiter les frottements que l'on pourrait avoir durant une éventuelle phase de repos ou de recul,
- à l'absence de chute entre le dégagement de la roue d'échappement et l'impulsion, et
- à la minimisation de l'inertie de la roue d'échappement.
- the low amplitude of the balance required to be able to be isochronous and not very sensitive to gravity, typically between 8 and 16 degrees,
- the absence of friction in the flexible pivot of the balance,
- the fact that the impulse is transmitted directly from the escape wheel to the balance, which eliminates any loss of energy associated with an intermediate moving body between the wheel and the balance,
- the fact that the detents make it possible to limit the friction that one could have during a possible phase of rest or recoil,
- the absence of a fall between the release of the escape wheel and the impulse, and
- minimizing the inertia of the escape wheel.
Un autre avantage du présent régulateur est que le défaut d'isochronisme de l'échappement à double détente compense naturellement le défaut d'isochronisme du pivot flexible de l'oscillateur. Cet effet est obtenu par le fait que contrairement aux échappements à détente classique, il y a toujours au moins une détente en contact avec le balancier. De plus, comme expliqué précédemment, le défaut d'isochronisme de l'échappement de la présente invention est réglable, ce qui permet de s'adapter au défaut de l'oscillateur qui peut varier d'un oscillateur à l'autre en raison des imprécisions de fabrication et d'assemblage des pièces.Another advantage of the present regulator is that the isochronism defect of the double expansion escapement naturally compensates for the isochronism defect of the flexible pivot of the oscillator. This effect is obtained by the fact that, unlike conventional trigger escapements, there is always at least one trigger in contact with the balance. In addition, as explained previously, the isochronism defect of the escapement of the present invention is adjustable, which makes it possible to adapt to the oscillator defect which can vary from one oscillator to another due to the manufacturing and assembly inaccuracies of parts.
Finalement, l'échappement à double détente du présent régulateur est auto-démarrant car d'une part il n'a pas de coup perdu contrairement aux échappements classiques à détente et d'autre part il ne nécessite pas d'élan particulier du balancier pour permettre le dégagement de la roue d'échappement. Par ailleurs, le profil des plans d'impulsion à effleurement implique un rapport de transmission variable qui augmente le couple appliqué à l'ancre par la roue d'échappement à la fin de l'impulsion, ce qui facilite l'auto-démarrage.
