Definitions
- the invention relates to an escape mechanism for a timepiece.
- the invention also relates to a watch movement comprising such an escapement mechanism.
- the invention relates to a timepiece comprising such a watch movement.
- the timepiece is for example a watch, a clock.
- a Swiss lever escapement comprises an escapement wheel (also called an anchor wheel), an anchor provided with inlet and outlet lifts, and a double plate.
- the Swiss lever escapement transmits the forces of the anchor wheel to the balance through the effects of levers and sliding inclined planes of the anchor wheel on the anchor.
- the teeth of the anchor wheel thus fulfill an impulse function on the anchor lifts.
- such a principle of force transmission is also the weak point of this type of exhaust.
- Maintaining friction conditions on sliding planes indeed involves systems of very delicate lubrication, and sensitive to aging. This is an important factor in varying gait and is thus liable to cause unstable gait in the positions.
- escapement of the Swiss anchor type requires having very high amplitudes at nine.
- a known solution consists in providing a coaxial escapement system anchored in the watch mechanism.
- the system typically comprises a triple coaxial wheel comprising a first escape wheel, a second escape wheel (also called a pulse pinion) and a drive pinion mounted coaxially in that order.
- the system also includes an intermediate wheel meshing with the drive pinion; as well as a balance plate, integral with a sprung balance.
- the balance plate carries a plate pin and a direct impulse vane arranged to cooperate with the first escape wheel.
- the anchor has an anchor inlet cooperating with the chainring pin, an impulse vane arranged to cooperate with the impulse pinion, and rest vane arranged to cooperate with the first escape wheel.
- the anchor coaxial escapement system transmits energy to the balance spring in the clockwise and anti-clockwise directions of the balance oscillations.
- a pulse is transmitted clockwise directly from a tooth of the first escape wheel to the chainring.
- Counterclockwise the impulse is delivered to the plate via the anchor, more precisely via the action of a tooth of the impulse pinion on the impulse vane of the anchor, then of the anchor inlet on the platform peg. After the impulses, the first escape wheel is at rest on the rest paddles and the balance oscillates freely, without disturbance.
- Such a coaxial exhaust mechanism Via its tangential force transmission system, such a coaxial exhaust mechanism is not dependent on lubrication for maintain the operating conditions of the mechanism. This system works like a gear and does not require any lubrication for the transmission of force. A large variation factor is therefore eliminated and contributes to a relatively stable rate in motion.
- Such a coaxial escapement mechanism also allows a constant transmission over time of the maintenance force of the sprung balance, and allows constant maintenance of the amplitude of the latter. Unlike the Swiss anchor type escapement, it is therefore no longer necessary to have very high amplitudes at nine. The step errors in the positions are thus reduced. Finally, this coaxial escapement mechanism allows a beneficial reduction in the angle of lift of the balance compared to the Swiss lever escapement.
- the lift angle is in fact reduced from 52 degrees for the Swiss anchor escapement to 37 degrees for the coaxial escapement. This ensures less disturbance of the balance at each alternation of the latter, compared to the Swiss lever escapement. This results in the constancy of the adjustment qualities of the watch and its precision.
- Such a coaxial escapement mechanism is therefore particularly intended for the manufacture of high precision chronometers.
- the patent document EP 1 045 297 A1 offers a dual coaxial wheel coaxial exhaust system.
- the system described in this document in fact comprises a double coaxial wheel comprising a first escape wheel and a second escape wheel.
- the system also includes an intermediate wheel meshing with the second escape wheel.
- the anchor has an anchor inlet cooperating with the plate peg, an impulse paddle arranged to cooperate with the second escape wheel, and rest paddles arranged to cooperate with the first escape wheel.
- the second escape wheel performs a dual function: that of the drive pinion meshing with the intermediate wheel and that of the escape wheel cooperating with the impulse pallet of the anchor.
- the object of the invention is therefore to provide an escapement mechanism for a timepiece which comprises a watch movement provided with a balance, making it possible to increase the inertia of the balance while limiting the bulk and the overall volume. of the movement, and while keeping all the optimization latitude on the number of teeth and the profile of the drive pinion.
- the invention relates to an escapement mechanism of a timepiece, which comprises the characteristics mentioned in independent claim 1.
- the escape mechanism according to the invention makes it possible to lower the plate of the intermediate wheel (which is typically the seconds wheel for a watch) in the watch movement. This advantageously frees space in the movement, which makes it possible to increase the volume and therefore the inertia of the balance.
- the quality of isochronism is consequently improved in the watch movement, and the rate variations reduced, while obtaining a very compact setting for the escapement mechanism.
- the impulse vane of the anchor has a height such that said impulse vane extends at the level of the teeth of the impulse pinion. This allows meshing between the anchor and the impulse pinion.
- the invention also relates to a watch movement comprising the escapement mechanism, and which comprises the characteristics mentioned in dependent claim 8.
- the invention also relates to a timepiece comprising the horological movement described above, and which comprises the characteristics mentioned in dependent claim 9.
- the figures 1 , 4a , 4b and 5 represent a part of a timepiece 1, which comprises a timepiece movement 2.
- the timepiece 1 is typically a watch, a clock.
- the watch movement 2 comprises an oscillator provided with a balance and a hairspring (not shown), an energy source (not shown) and an escape mechanism 4 placed between the energy source and the oscillator.
- the escape mechanism shown in figures 1 to 4b is a coaxial escapement 4, and comprises a triple coaxial wheel 6, an intermediate wheel 8, a balance plate (not shown) and an anchor 12.
- the escape mechanism illustrated on figure 5 is a classic escapement comprising two levels with an anchor 12, an escape wheel and a balance.
- the triple coaxial wheel 6 comprises a first escape wheel 14, a drive pinion 16 and a second escape wheel 18 called the impulse pinion.
- the first escape wheel 14, the drive pinion 16 and the impulse pinion 18 are mounted on a same axis X1. More precisely, the first escape wheel 14, the drive pinion 16 and the impulse pinion 18 are mounted coaxially, in this order, on the axis X1. In other words, the drive pinion 16 is mounted coaxially on the first escape wheel 14, and the impulse pinion 18 is mounted coaxially on the drive pinion 16.
- the coaxial escape mechanism 4 advantageously allows the board (not shown) of the intermediate wheel 8 to be lowered into the watch movement 2, at the level of the drive pinion 16. This advantageously frees up space in the watch movement 2, which makes it possible to increase the volume and therefore the inertia of the balance.

Description
L'invention concerne un mécanisme d'échappement pour une pièce d'horlogerie.The invention relates to an escape mechanism for a timepiece.
L'invention concerne également un mouvement horloger comprenant un tel mécanisme d'échappement.The invention also relates to a watch movement comprising such an escapement mechanism.
L'invention concerne enfin une pièce d'horlogerie comprenant un tel mouvement horloger. La pièce d'horlogerie est par exemple une montre, une horloge.Finally, the invention relates to a timepiece comprising such a watch movement. The timepiece is for example a watch, a clock.
Dans le domaine des mouvements horlogers, il est connu des systèmes assurant la fonction d'échappement. L'échappement est classiquement placé entre la source d'énergie du mouvement horloger et l'oscillateur de type balancier-spiral. L'échappement a pour but de compter et d'entretenir les oscillations du balancier-spiral. Typiquement, il est connu d'utiliser dans certaines montres mécaniques un échappement de type ancre suisse. Un tel échappement à ancre suisse comprend une roue d'échappement (appelée aussi roue d'ancre), une ancre munie de levées d'entrée et de sortie, et un double plateau. L'échappement à ancre suisse transmet les forces de la roue d'ancre au balancier par des effets de leviers et de plans inclinés glissants de la roue d'ancre sur l'ancre. Les dents de la roue d'ancre remplissent ainsi une fonction d'impulsion sur les levées d'ancre. Toutefois, un tel principe de transmission des forces est aussi le point faible de ce type d'échappement. Le maintien des conditions de frottement sur des plans glissants implique en effet des systèmes de lubrification très délicats, et sensibles au vieillissement. Ceci constitue un important facteur de variation de la marche et est ainsi susceptible de provoquer une marche instable dans les positions. En outre, un tel échappement de type ancre suisse impose d'avoir des amplitudes à neuf très élevées.In the field of watch movements, systems are known which provide the escapement function. The escapement is conventionally placed between the energy source of the watch movement and the balance-spring type oscillator. The purpose of the escapement is to count and maintain the oscillations of the sprung balance. Typically, it is known to use in certain mechanical watches an escapement of the Swiss anchor type. Such a Swiss lever escapement comprises an escapement wheel (also called an anchor wheel), an anchor provided with inlet and outlet lifts, and a double plate. The Swiss lever escapement transmits the forces of the anchor wheel to the balance through the effects of levers and sliding inclined planes of the anchor wheel on the anchor. The teeth of the anchor wheel thus fulfill an impulse function on the anchor lifts. However, such a principle of force transmission is also the weak point of this type of exhaust. Maintaining friction conditions on sliding planes indeed involves systems of very delicate lubrication, and sensitive to aging. This is an important factor in varying gait and is thus liable to cause unstable gait in the positions. In addition, such an escapement of the Swiss anchor type requires having very high amplitudes at nine.
Afin de remédier à ces inconvénients, une solution connue consiste à prévoir un système d'échappement coaxial à ancre dans le mécanisme horloger. Outre l'ancre, le système comprend typiquement une roue coaxiale triple comportant une première roue d'échappement, une deuxième roue d'échappement (appelée aussi pignon d'impulsion) et un pignon d'entraînement montés coaxialement dans cet ordre. Le système comprend également une roue intermédiaire engrenant avec le pignon d'entraînement ; ainsi qu'un plateau de balancier, solidaire d'un balancier-spiral. Le plateau de balancier porte une cheville de plateau et une palette d'impulsion directe arrangée pour coopérer avec la première roue d'échappement. L'ancre comporte une entrée d'ancre coopérant avec la cheville de plateau, une palette d'impulsion arrangée pour coopérer avec le pignon d'impulsion, et des palettes de repos arrangées pour coopérer avec la première roue d'échappement. Le système d'échappement coaxial à ancre transmet l'énergie au balancier-spiral dans les sens horaire et anti-horaire des oscillations du balancier. Une impulsion est transmise dans le sens horaire directement d'une dent de la première roue d'échappement au plateau. Dans le sens antihoraire l'impulsion est délivrée au plateau via l'ancre, plus précisément via l'action d'une dent du pignon d'impulsion sur la palette d'impulsion de l'ancre, puis de l'entrée d'ancre sur la cheville de plateau. Après les impulsions, la première roue d'échappement est en repos sur les palettes de repos et le balancier effectue ses oscillations librement, sans perturbation.In order to remedy these drawbacks, a known solution consists in providing a coaxial escapement system anchored in the watch mechanism. In addition to the anchor, the system typically comprises a triple coaxial wheel comprising a first escape wheel, a second escape wheel (also called a pulse pinion) and a drive pinion mounted coaxially in that order. The system also includes an intermediate wheel meshing with the drive pinion; as well as a balance plate, integral with a sprung balance. The balance plate carries a plate pin and a direct impulse vane arranged to cooperate with the first escape wheel. The anchor has an anchor inlet cooperating with the chainring pin, an impulse vane arranged to cooperate with the impulse pinion, and rest vane arranged to cooperate with the first escape wheel. The anchor coaxial escapement system transmits energy to the balance spring in the clockwise and anti-clockwise directions of the balance oscillations. A pulse is transmitted clockwise directly from a tooth of the first escape wheel to the chainring. Counterclockwise the impulse is delivered to the plate via the anchor, more precisely via the action of a tooth of the impulse pinion on the impulse vane of the anchor, then of the anchor inlet on the platform peg. After the impulses, the first escape wheel is at rest on the rest paddles and the balance oscillates freely, without disturbance.
Via son système de transmission tangentielle de la force, un tel mécanisme d'échappement coaxial n'est pas tributaire de la lubrification pour maintenir les conditions de fonctionnement du mécanisme. Ce système fonctionne en effet comme un engrenage et ne nécessite, pour la transmission de la force, aucune lubrification. Un important facteur de variation est par conséquent éliminé et contribue à une marche relativement stable dans le mouvement. Un tel mécanisme d'échappement coaxial permet en outre une transmission constante dans le temps de la force d'entretien du balancier-spiral, et permet un maintien constant de l'amplitude de ce dernier. Il n'est ainsi plus nécessaire, contrairement à l'échappement de type ancre suisse, d'avoir des amplitudes à neuf très élevées. Les erreurs de marches dans les positions sont ainsi diminuées. Enfin, ce mécanisme d'échappement coaxial permet une réduction profitable de l'angle de levée du balancier par rapport à l'échappement ancre suisse. L'angle de levée est en effet réduit de 52 degrés pour l'échappement ancre suisse à 37 degrés pour l'échappement coaxial. Ceci assure une perturbation moindre du balancier à chaque alternance de ce dernier, par rapport à l'échappement ancre suisse. Il en résulte la constance des qualités de réglage de la montre et sa précision. Un tel mécanisme d'échappement coaxial est donc particulièrement destiné à la fabrication de chronomètres de haute précision.Via its tangential force transmission system, such a coaxial exhaust mechanism is not dependent on lubrication for maintain the operating conditions of the mechanism. This system works like a gear and does not require any lubrication for the transmission of force. A large variation factor is therefore eliminated and contributes to a relatively stable rate in motion. Such a coaxial escapement mechanism also allows a constant transmission over time of the maintenance force of the sprung balance, and allows constant maintenance of the amplitude of the latter. Unlike the Swiss anchor type escapement, it is therefore no longer necessary to have very high amplitudes at nine. The step errors in the positions are thus reduced. Finally, this coaxial escapement mechanism allows a beneficial reduction in the angle of lift of the balance compared to the Swiss lever escapement. The lift angle is in fact reduced from 52 degrees for the Swiss anchor escapement to 37 degrees for the coaxial escapement. This ensures less disturbance of the balance at each alternation of the latter, compared to the Swiss lever escapement. This results in the constancy of the adjustment qualities of the watch and its precision. Such a coaxial escapement mechanism is therefore particularly intended for the manufacture of high precision chronometers.
Toutefois, ce type de mécanisme d'échappement coaxial est relativement encombrant, ce qui est préjudiciable à la compacité de l'ensemble. Afin de répondre à ce problème, le document brevet
L'invention a donc pour but de fournir un mécanisme d'échappement pour une pièce d'horlogerie qui comporte un mouvement horloger muni d'un balancier, permettant d'augmenter l'inertie du balancier tout en limitant l'encombrement et le volume global du mouvement, et tout en gardant toute la latitude d'optimisation sur le nombre de dents et le profil du pignon d'entrainement.The object of the invention is therefore to provide an escapement mechanism for a timepiece which comprises a watch movement provided with a balance, making it possible to increase the inertia of the balance while limiting the bulk and the overall volume. of the movement, and while keeping all the optimization latitude on the number of teeth and the profile of the drive pinion.
A cet effet, l'invention concerne un mécanisme d'échappement d'une pièce d'horlogerie, qui comprend les caractéristiques mentionnées dans la revendication indépendante 1.To this end, the invention relates to an escapement mechanism of a timepiece, which comprises the characteristics mentioned in
Des formes particulières du mécanisme d'échappement sont définies dans les revendications dépendantes 2 à 5.Particular forms of the escape mechanism are defined in
Grâce à la configuration particulière entre la première roue d'échappement, le pignon d'entraînement et le pignon d'impulsion, plus précisément au fait que ces éléments sont montés coaxialement dans cet ordre, le mécanisme d'échappement selon l'invention permet de descendre la planche de la roue intermédiaire (qui est typiquement la roue des secondes pour une montre) dans le mouvement horloger. Ceci libère avantageusement de l'espace dans le mouvement, ce qui permet d'augmenter le volume et donc l'inertie du balancier. La qualité de l'isochronisme est par conséquent améliorée dans le mouvement horloger, et les variations de marche réduites, tout en obtenant un réglage très compact pour le mécanisme d'échappement.Thanks to the particular configuration between the first escape wheel, the drive pinion and the impulse pinion, more precisely to the fact that these elements are mounted coaxially in this order, the escape mechanism according to the invention makes it possible to lower the plate of the intermediate wheel (which is typically the seconds wheel for a watch) in the watch movement. This advantageously frees space in the movement, which makes it possible to increase the volume and therefore the inertia of the balance. The quality of isochronism is consequently improved in the watch movement, and the rate variations reduced, while obtaining a very compact setting for the escapement mechanism.
Avantageusement, la palette d'impulsion de l'ancre présente une hauteur telle que ladite palette d'impulsion s'étend au niveau des dents du pignon d'impulsion. Ceci permet l'engrènement entre l'ancre et le pignon d'impulsion.Advantageously, the impulse vane of the anchor has a height such that said impulse vane extends at the level of the teeth of the impulse pinion. This allows meshing between the anchor and the impulse pinion.
A cet effet, l'invention concerne également un mouvement horloger comportant le mécanisme d'échappement, et qui comprend les caractéristiques mentionnées dans la revendication dépendante 8.To this end, the invention also relates to a watch movement comprising the escapement mechanism, and which comprises the characteristics mentioned in dependent claim 8.
A cet effet, l'invention concerne également une pièce d'horlogerie comportant le mouvement horloger décrit ci-dessus, et qui comprend les caractéristiques mentionnées dans la revendication dépendante 9.To this end, the invention also relates to a timepiece comprising the horological movement described above, and which comprises the characteristics mentioned in dependent claim 9.
