Description

La présente invention se rapporte à un mécanisme de quantième annuel pour mouvement d'horlogerie comprenant un mobile des quantièmes à 31 dents, un sautoir en prise avec sa denture, un satellite des mois, dont l'axe de rotation est solidaire de ce mobile des quantièmes et qui comporte cinq dents d'entraínement d'une denture de douze pas pour les mois de moins de 31 jours, une denture planétaire fixe, coaxiale au mobile des quantièmes, en liaison desmodromique avec le satellite des mois et un organe d'entraínement du mobile des quantièmes en liaison d'entraínement avec la roue des heures du mouvement d'horlogerie et comportant deux doigts d'entraínement, le premier coupant la trajectoire de la denture du mobile des quantièmes, le second coupant la trajectoire de la denture du satellite des mois lorsque son axe de révolution est aligné avec ceux de la denture planétaire, de l'organe d'entraínement et du mobile des quantièmes.The present invention relates to a mechanism for annual calendar for a watch movement comprising a mobile calendar of 31 teeth, a jumper in engagement with its toothing, a satellite of months, whose axis of rotation is in solidarity with this calendar of dates and which includes five drive teeth of a twelve step toothing for months less than 31 days, fixed planetary toothing, coaxial mobile dates, in conjunction desmodromic with the satellite of the months and a drive organ of the mobiles of dates in connection with training with the wheel of the hours of the watch movement and having two fingers of training, the first cutting the trajectory of the toothing the mobile of the dates, the second cutting the trajectory of the satellite toothing of the months when its axis of revolution is aligned with those of the planetary toothing, the drive member and mobile dates.

Un tel mécanisme de quantième annuel, associé à un mécanisme de quantième perpétuel, est décrit dans le EP 1 351 104. Ce mécanisme comporte un satellite des mois dont l'axe de pivotement est solidaire d'une roue des quantièmes qui fait un tour par mois. Ce satellite des mois comporte douze dents dont sept sont tronquées et cinq ne le sont pas. Les douze dents de ce satellite engrènent avec une denture planétaire fixe de sept dents, coaxiale à la roue des quantièmes.Such an annual calendar mechanism, associated with a mechanism Perpetual calendar, is described in EP 1,351 104. This mechanism includes a satellite of the months whose axis of pivoting is integral with a date wheel which go round once a month. This satellite of the months has twelve teeth of which seven are truncated and five are not. The twelve teeth of this satellite meshing with planetary gearing fixed of seven teeth, coaxial with the date wheel.

Durant l'année, à chaque tour de la roue des quantièmes, la denture du satellite des mois occupe une position différente lorsque son axe de pivotement est aligné sur l'axe de la denture planétaire et l'axe de pivotement d'une roue qui fait un tour en vingt-quatre heures pour l'entraínement de la roue des quantièmes. A cet effet, cette roue de vingt-quatre heures comporte vingt-quatre dents dont vingt sont tronquées et parmi les quatre autres, une est une dent d'entraínement normal qui vient en prise avec la roue des quantièmes une fois par jour et une autre est une dent de correction annuelle, décalée parallèlement à son axe de rotation, pour venir en prise avec une des cinq dents non tronquées du satellite des mois chaque fois que le mois a moins de trente et un jours.During the year, at each turn of the date wheel, the teeth of the satellite of the months occupies a position different when its pivot axis is aligned with the axis of the planetary toothing and the pivot axis of a wheel who makes a turn in twenty-four hours for training of the date wheel. For this purpose, this wheel of twenty-four hours has twenty-four teeth of which twenty are truncated and among the other four, one is a tooth normal drive that engages with the wheel of dates once a day and another is a tooth of annual correction, shifted parallel to its axis of rotation, to engage one of the five teeth truncated satellite every month that the month has less than thirty-one days.

Lorsque le mois a moins de 31 jours, une des cinq dents non tronquées du satellite des mois recouvre une des dents de la roue des quantièmes et est située dans la trajectoire d'une dent de correction de la roue qui fait un tour en vingt-quatre heures, en sorte qu'en tournant, la dent de correction de cette roue, décalée parallèlement à son axe de rotation, fait tourner le satellite des mois, lequel étant en prise avec la denture planétaire fixe, fait tourner la roue des quantièmes avant que le doigt d'entraínement normal de cette roue de vingt-quatre heure ne fasse tourner la roue des quantièmes d'un pas, comme elle le fait à chaque rotation, en sorte que la roue des quantièmes est déplacée de deux pas pour un tour de la roue de vingt-quatre heures.When the month is less than 31 days, one of five teeth truncated satellite of the month covers one of the teeth of the date wheel and is located in the trajectory of a wheel correction tooth that makes a turn in twenty-four hours, so that by turning, the correction tooth of this wheel, shifted parallel to its axis of rotation, rotate the satellite of the months, which is taken with fixed planetary toothing, rotates the wheel dates before the normal training finger of this twenty-four hour wheel does turn the wheel of of one step, as it does at each rotation, in so that the date wheel is moved two steps for a twenty-four hour round of the wheel.

Ce mécanisme présente l'avantage d'éviter les dispositifs à cames et leviers tels que ceux décrits dans le CH 685 585 ou dans le EP 987 609, qui utilisent de l'énergie, sont délicats à mettre au point et sont donc peu fiables.This mechanism has the advantage of avoiding the devices with cams and levers such as those described in CH 685 585 or in EP 987 609, which use energy, are delicate to develop and are therefore unreliable.

Bien que de conception séduisante, ce mécanisme présente cependant un important inconvénient provenant du fait que le satellite des mois travaille sur un premier cercle primitif avec la denture planétaire fixe, tandis qu'il travaille sur un second cercle primitif, plus grand que le premier, avec les dents d'entraínement de la roue de vingt-quatre heures. Ce plus grand diamètre primitif est nécessaire pour éviter que les dents d'entraínement de la roue de vingt-quatre heures ne puisse venir en prise avec les dents tronquées du satellite des mois. Par conséquent, la pénétration entre les dents de la roue de vingt-quatre heures dans la denture du satellite des mois est faible, de même que la valeur angulaire de la menée. Un tel mécanisme ne présente donc pas une grande fiabilité et est pour le moins extrêmement difficile à mettre au point, conduisant à des retouches pièce par pièce.Although of attractive design, this mechanism presents however, a major drawback from the fact that satellite of the months is working on a first primitive circle with fixed planetary toothing, while working on a second primitive circle, larger than the first, with the drive teeth of the twenty-four hour wheel. This larger primitive diameter is necessary to avoid that the drive teeth of the twenty-four wheel hours can not come into contact with the truncated teeth of satellite of the months. Therefore, penetration between teeth of the twenty-four hour wheel in the teeth of the months satellite is weak, as is the value angular of the led. Such a mechanism does not therefore present high reliability and is extremely extreme difficult to develop, leading to retouching by piece.

Un inconvénient supplémentaire de cette solution vient du fait que lorsque l'axe de révolution du satellite des mois est aligné avec les axes de révolution respectifs de la denture planétaire et de la roue de vingt-quatre heures, le satellite se situe entre eux, en sorte que l'entraínement de ce satellite se fait sur une partie de sa denture située la plus éloignée du centre de la roue des quantièmes par la roue vingt-quatre heures située à l'extérieur de cette roue des quantièmes, ce qui réduit l'angle de menée au minimum, la pénétration et l'angle de menée étant déjà réduits du fait que le diamètre primitif entre cette roue de vingt-quatre heures et le satellite des mois est agrandi par rapport au diamètre primitif entre ce satellite et la denture planétaire. La réalisation et la mise au point d'un tel mécanisme est donc problématique et sa fiabilité est faible.A further disadvantage of this solution comes because when the axis of revolution of the satellite months is aligned with the respective axes of revolution of the planetary gearing and the twenty-four hour wheel, the satellite is located between them, so that the training of this satellite is done on a part of its teeth located the further away from the center of the date wheel by the wheel twenty-four hours located outside this wheel of months, which reduces the driving angle to a minimum, penetration and the angle of lead being already reduced by that the pitch diameter between this wheel of twenty-four hours and months satellite is enlarged relative to the pitch diameter between this satellite and the teeth planetary. The realization and the development of such a mechanism is therefore problematic and its reliability is low.

On peut donc en conclure que, malgré l'existence de la solution faisant l'objet du EP 1 351 104, il n'a pas encore été proposé d'alternative crédible aux mécanismes de quantièmes annuels utilisant des cames et des leviers.It can therefore be concluded that, despite the existence of the solution which is the subject of EP 1 351 104, it has not yet has been proposed credible alternative to the mechanisms of date using cams and levers.

Le but de la présente invention est de remédier, au moins en partie, aux inconvénients susmentionnés.The object of the present invention is to remedy the less in part, to the aforementioned drawbacks.

A cet effet, la présente invention a pour objet un mécanisme de quantième selon la revendication 1.For this purpose, the subject of the present invention is a mechanism date calendar according to claim 1.

L'avantage essentiel de cette invention vient du fait que la présence de deux satellites coaxiaux dont chacun remplit une fonction distincte permet à chacun d'eux de travail-1er avec des dentures normales, chaque denture ne travaillant que sur un seul cercle primitif, les cercles primitifs respectifs des deux mobiles engrenant l'un avec l'autre étant tangents. Ces conditions d'engrenage permettent aux dentures d'avoir des pénétrations optimales, donc des angles de menées aptes à produire un entraínement fiable, ce qui n'est pas le cas lorsque l'on travaille à proximité des extrémités des dents.The essential advantage of this invention is that that the presence of two coaxial satellites each of which fills a separate function allows each of them to work-1st with normal toothings, each toothing not working only on a single primitive circle, the respective primitive circles of the two mobiles meshing with each other being tangent. These gear conditions allow the teeth to have optimal penetrations, so angles of led able to produce a reliable training, which is not the case when working near the ends of the teeth.

La conception d'un mécanisme de quantième annuel, sans bascule ni levier, avec des pénétrations et des angles de menée optimaux selon la présente invention, rend tout réglage de ce mécanisme superflu. Ceci constitue un facteur important de fiabilité dans la mesure où, d'une part, tout réglage comporte une marge de tolérance et, d'autre part, tout réglage est susceptible de se dérégler. La bascule de saut instantané, utilisée avec la forme préférée de changement instantané des quantièmes n'entre pas en compte, du fait qu'elle ne participe pas à la correction du nombre de jours des mois du mécanisme de quantième annuel selon l'invention, mais sert uniquement à délivrer une énergie accumulée pour l'entraínement instantané du mobile des quantièmes.The design of an annual calendar mechanism, without rocker or lever, with penetrations and angles of conduct according to the present invention, makes any adjustment of this superfluous mechanism. This is an important factor reliability in so far as, on the one hand, any adjustment involves a margin of tolerance and, on the other hand, any adjustment is likely to go wrong. The instant jump rocker, used with the preferred form of instant change dates do not count, because it does not participate not to correct the number of days of the months of the mechanism annual calendar according to the invention, but only serves to deliver accumulated energy for training instantaneous mobile dates.

Avantageusement, l'axe de révolution de l'organe d'entraínement du mobile des quantièmes, lorsqu'il est aligné avec les axes de révolution respectifs des satellites et de la denture planétaire, est situé entre leurs axes de révolution.Advantageously, the axis of revolution of the drive member mobile dates, when aligned with the respective axes of revolution of the satellites and the planetary toothing, is located between their axes of revolution.

Grâce à cette caractéristique, la menée peut être encore améliorée.Thanks to this characteristic, the led can be still improved.

De préférence, le second satellite a un diamètre sensiblement supérieur à celui du satellite des mois. De ce fait, l'entraínement du satellite des mois par le doigt de correction s'effectue sur un rayon primitif plus petit que celui du second satellite. Grâce à cette particularité, le sens de rotation des satellites lors de leur entraínement par le second doigt d'entraínement est le même que celui de l'organe d'entraínement portant ledit second doigt.Preferably, the second satellite has a substantially higher than the satellite of the months. Thereby, the training of the satellite of the months by the finger of correction on a prime radius smaller than that of the second satellite. Thanks to this particularity, the meaning of rotation of the satellites during their training by the second training finger is the same as that of the organ drive carrying said second finger.

Par ce mode d'entraínement que l'on peut qualifier de pseudo-paradoxal, on augmente encore l'angle de menée et donc la sécurité du mécanisme.By this mode of training that can be described as pseudo-paradoxical, we further increase the lead angle and therefore the security of the mechanism.

De préférence, le mobile des quantièmes portant le satellite des mois est un anneau ou disque des quantièmes coaxial au centre du mouvement d'horlogerie, permettant ainsi d'avoir des organes de plus grandes dimensions qu'avec un mécanisme déporté. En outre, la disposition des satellites sur le mobile des quantièmes permet de réduire le nombre de pièces, aucun renvoi n'étant nécessaire entre le mécanisme de quantième annuel et le mobile des quantièmes.Preferably, the mobile of the dates carrying the satellite months is a ring or disc coaxial date at the center of the watch movement, thus allowing to have organs of larger dimensions than with a remote mechanism. In addition, satellite layout on mobile dates can reduce the number of parts, no reference being necessary between the mechanism of annual calendar and mobile dates.

La fiabilité de ce mécanisme, qui utilise exclusivement des engrenages, avec de bonnes pénétrations de leurs dentures et des angles de menées aptes à assurer le bon fonctionnement du mobile des quantièmes, se prête particulièrement bien à être entraíné par un mécanisme d'entraínement à saut instantané. Avantageusement, dans ce cas, le mobile des quantièmes présente la forme d'un anneau.The reliability of this mechanism, which uses exclusively gears, with good penetrations of their teeth and angles of operations able to ensure the proper functioning of mobile dates, is particularly suitable for be driven by an instant jump drive mechanism. Advantageously, in this case, the mobile of the calendars has the shape of a ring.

Cette roue 5 est entraínée à raison d'un tour en vingt-quatre heures par la roue des heures 6 du mouvement d'horlogerie et par l'intermédiaire d'un mobile 6a.The date mechanism object of the invention comprises a mobile calendar of dates, preferably under the shape of a date ring 1 also called disc of calendars. The inner edge of this ring of dates 1 has 31 teeth positioned by a jumper spring 2. The daily training of this ring of dates is achieved by a drive finger 3a integral with an organ 3 secured to an instantaneous jump cam 4 connected to a wheel 5 by means of a pin 4a in taken with an opening in an arc 5a formed in the wheel 5. This wheel 5 is driven at the rate of one turn in twenty-four hours by the hour wheel 6 of the movement timepieces and via a mobile phone 6a.

    Une bascule 7 est appliquée contre le pourtour de la came de saut instantané 4 par un ressort 8 destiné à faire tourner brusquement la came 4 dans le sens des aiguilles de la montre dès qu'elle arrive à l'extrémité de la rampe d'armage 4b du ressort 8 pour entraíner l'organe d'entraínement 3 de l'anneau des quantièmes 1.A rocker 7 is applied against the periphery of the instant jump cam 4 by a spring 8 intended to make turn cam 4 sharply clockwise the watch as soon as it arrives at the end of the arming ramp 4b of the spring 8 to drive the drive member 3 of the date ring 1.

    Ce qui vient d'être décrit correspond à un mécanisme simple de quantième instantané, dans lequel, l'anneau des quantièmes 1 est entraíné d'un pas toutes les vingt-quatre heures, ce qui nécessite d'effectuer une correction cinq fois par an à la fin des mois de moins de trente et un jours. What has just been described corresponds to a mechanism simple instantaneous date, in which, the ring of dates 1 is driven one step every twenty-four hours, which requires a correction five times per year at the end of the months of less than thirty-one days.

    Nous allons décrire maintenant les composants qui permettent de passer du quantième simple décrit ci-dessus à un quantième annuel. A cet effet, une denture planétaire 9 est fixée au bâti du mouvement d'horlogerie, concentriquement à l'anneau des quantièmes 1. Un pignon satellite 10 dont le nombre de dents est de douze ou, de préférence, un multiple de douze est monté pivotant autour d'un axe solidaire de l'anneau des quantièmes 1. Ce pignon satellite 10 est constamment en prise avec la denture planétaire 9, formant avec elle un engrenage épicycloïdal simple qui fait un tour par mois. Un second pignon satellite des mois 11 ne comportant que cinq dents sur douze est solidaire et coaxial au pignon satellite 10. De préférence, le diamètre du pignon satellite des mois 11 est inférieur à celui du pignon satellite 10.We will now describe the components that allow to go from the simple date described above to a annual calendar. For this purpose, a planetary toothing 9 is fixed to the watchmaking frame, concentrically to date ring 1. A satellite pinion 10 whose number of teeth is twelve or, preferably, a multiple of twelve is pivotally mounted about an integral axis of the ring of dates 1. This pinion satellite 10 is constantly engaged with the planetary toothing 9, forming with it a simple epicyclic gear that makes a turn through month. A second satellite gear of the months 11 not including that five teeth out of twelve is integral and coaxial with the pinion satellite 10. Preferably, the diameter of the satellite pinion months 11 is less than that of the planet gear 10.

    Enfin, l'organe d'entraínement 3 porte un second doigt 3b décalé, d'une part angulairement, en avant par rapport au sens de rotation correspondant à celui des aiguilles de la montre de cet organe d'entraínement 3, d'autre part parallèlement à son axe de rotation. Ce second doigt 3b de l'organe d'entraínement 3 constitue un doigt de correction destiné à entraíner l'anneau des quantièmes 1 d'un pas supplémentaire à la fin de chaque mois de moins de 31 jours.Finally, the training member 3 carries a second finger 3b offset, on the one hand angularly, forward relative to the direction of rotation corresponding to that of the hands of the shows this training member 3, on the other hand in parallel to its axis of rotation. This second finger 3b of the organ 3 constitutes a correction finger for drive the ring of the dates 1 of an additional step to the end of each month of less than 31 days.

    Le principe sur lequel le mécanisme de correction fonctionne consiste à amener le 30 de chaque mois de moins de 31 jours une des cinq dents du pignon satellite des mois 11 sensiblement en alignement avec la droite joignant les axes de révolution respectifs du planétaire 9, de l'organe d'entraínement 3 du mobile des quantièmes 1 et des satellites 10, 11, comme illustré sur la figure 2.The principle on which the correction mechanism works is to bring the 30th of each month under 31 days one of the five teeth of the satellite gear of the months 11 substantially in alignment with the line joining the axes of the respective revolution of the sun gear 9, of the training 3 mobile dates and satellites 1 10, 11, as illustrated in FIG. 2.

    Dès que la bascule 7 arrive au-delà de l'extrémité de la courbe d'armage 4b de la came de saut instantané 4, elle fait tourner brusquement cette came 4 et l'organe d'entraínement 3 qui lui est solidaire dans le sens des aiguilles de la montre. Cette rotation brusque de la came 4 est rendue possible grâce à l'ouverture en arc de cercle 5a dans laquelle la cheville 4a de la came 4 est engagée. Au cours de ce mouvement, le doigt de correction 3b qui est en contact avec une des cinq dents du pignon satellite des mois 11 est entraíné. Etant donné d'une part, que ce satellite 11 est solidaire du satellite 10 de plus grand diamètre qui est en prise avec le planétaire 9 et d'autre part, que l'organe d'entraínement 3 est situé entre l'axe de révolution du planétaire 9 et l'axe de révolution des satellites 10, 11, le déplacement du satellite 11 par le doigt de correction 3b se traduit par une rotation de ce satellite 11 dans le sens des aiguilles de la montre, c'est-à-dire dans le même sens que l'organe d'entraínement 3. Cet engrenage que l'on peut qualifier de pseudo-paradoxal permet d'augmenter l'angle de contact entre le doigt de correction 3b et le pignon satellite 11, améliorant la sécurité du déplacement et garantissant que l'anneau des quantièmes 1 ne sera pas ramené en arrière par le sautoir 2, mais au contraire, que celui-ci terminera l'entraínement de l'anneau des quantièmes en le déplaçant dans le sens des aiguilles de la montre.As soon as flip-flop 7 reaches beyond the end of the winding curve 4b of the instantaneous jump cam 4, it makes turn suddenly this cam 4 and the drive member 3 which is solidarity with it in the sense of the needles of the shows. This sudden rotation of the cam 4 is made possible thanks to the opening in an arc 5a in which the peg 4a of the cam 4 is engaged. During this movement, the correction finger 3b that is in contact with one of the five teeth of the satellite gear of the months 11 is causes. Given, on the one hand, that this satellite 11 is in solidarity with the larger diameter satellite 10 which is taken with the sun gear 9 and on the other hand, that the organ 3 is located between the axis of revolution of the sun gear 9 and the axis of revolution of the satellites 10, 11, the displacement of the satellite 11 by the correction finger 3b se translated by a rotation of this satellite 11 in the direction of needles of the watch, that is to say in the same direction as the drive member 3. This gear that can be called of pseudo-paradoxal makes it possible to increase the angle of contact between the correction finger 3b and the satellite pinion 11, improving the safety of the movement and ensuring that the ring of the dates 1 will not be brought back by the jumper 2, but on the contrary, that it will finish training the date ring by moving it clockwise.

    A la fin de cette première phase d'entraínement, les composants du mécanisme de quantième se trouvent dans la position illustrée par la figure 3, c'est-à-dire que l'anneau des quantièmes 1 a été avancé d'un pas au 31. Au cours de la seconde phase, c'est le doigt d'entraínement normal 3a qui prend le relais et déplace le disque comme il le fait toutes les vingt-quatre heures, pour amener le "1" du mois suivant dans le guichet 13 dont la position est indiquée en traits mixtes.At the end of this first phase of training, components of the date mechanism are found in the position illustrated in Figure 3, that is to say that the ring dates 1 has been advanced by one step to 31. During the second phase is the normal training finger 3a which takes over and moves the disc like he does all twenty-four hours, to bring the "1" of the following month in the window 13 whose position is indicated in lines mixed.

    Il est évident que les deux phases d'entraínement de l'anneau des quantièmes qui viennent d'être décrites se succèdent sans interruption, dans le même déplacement angulaire de la came de saut instantané 4, la durée totale d'entraínement n'étant que de quelques centièmes de secondes, elle n'est donc pas perceptible à l'oeil nu.It is obvious that the two training phases of the ring of the dates which have just been described succeed without interruption, in the same angular displacement of the instantaneous jump cam 4, the total duration of training being only a few hundredths of a second, it is therefore not perceptible to the naked eye.

    Pour que les cinq dents du pignon satellite 11 soient disposées dans la bonne position à la fin de chaque mois en fonction du nombre de jour du mois, il faut évidemment que le nombre de tours du satellite par tour de l'anneau des quantièmes soit un nombre non entier. Toutefois cette condition n'est pas suffisante.So that the five teeth of the satellite gear 11 are placed in the right position at the end of each month in depending on the number of days of the month, it is obviously necessary that the number of satellite revolutions per revolution of the date ring a non-integer number. However this condition it's not enough.

    La première condition à remplir est évidemment que le satellite 10 qui représente les mois, présente un nombre de dents correspondant à douze ou un multiple de douze. En ce qui concerne le satellite des mois à cinq dents réparties sur un pignon de douze pas, ses cinq dents doivent être soit disposées sur cinq pas consécutifs, soit réparties chronologiquement, comme se succèdent les mois de moins de trente et un jours et les mois de trente et un jours ou dans la chronologie inverse.The first condition to fulfill is obviously that the satellite 10 which represents the months, presents a number of teeth corresponding to twelve or a multiple of twelve. In this which concerns the satellite of the five-toothed months spread over a twelve step pinion, his five teeth must be either arranged in five consecutive steps, or distributed chronologically, as one succeeds the months of less than thirty and a day and the months of thirty-one days or in the timeline reverse.

    Il a été possible d'établir, de manière empirique, une formule pour calculer le nombre de dents du planétaire 9 capable d'amener une des cinq dents du pignon satellite en alignement avec les axes de révolution respectifs des satellites 10, 11, de l'organe d'entraínement 3 du mobile des quantièmes 1 et du planétaire 9, le 30 de chacun des mois de moins de trente et un jours. Cette condition est satisfaite pour tous les nombres ou un multiple de ceux-ci obtenus par la formule suivante: zi+1 = zl + 3 + (-1)', avec i = 1,2,3,..., et zl = 5It has been possible to establish, empirically, a formula for calculating the number of teeth of the sun gear 9 capable of bringing one of the five teeth of the satellite gear in alignment with the respective axes of revolution of the satellites 10, 11, 11 3 drive member of the mobile date and 1 of the planetary 9, the 30 of each month less than thirty-one days. This condition is satisfied for all numbers or multiples thereof obtained by the following formula: z i + 1 = z l + 3 + (-1) ', with i = 1,2,3, ..., and z l = 5

    Afin de garantir un positionnement angulaire le plus précis possible du satellite des mois 11 par rapport au doigt de correction 3b, les nombres de dents respectifs du satellite 10 et du planétaire 9 sont choisis aussi grands que possible, ce qui permet de réduire le jeu angulaire du pignon satellite 10 et donc celui du pignon satellite des mois à cinq dents 11. Dans l'exemple décrit, le planétaire a 123 dents alors que le pignon satellite 10 en a 36.In order to guarantee the most angular positioning precise possible satellite of the months 11 compared to the finger 3b, the respective numbers of teeth of the satellite 10 and the sun gear 9 are chosen as large as possible, which reduces the angular clearance of the pinion satellite 10 and therefore that of the satellite gear of the months to five teeth 11. In the example described, the sun gear has 123 teeth while the planet gear 10 has 36.

    Suivant le nombre de dents du planétaire 9, choisi par la formule ci-dessus, les cinq dents du pignon satellite des mois 11 devront être réparties, non pas groupées comme dans l'exemple représenté, mais séparées par des vides égaux à un ou deux pas, suivant que le mois de moins de trente et un jours est suivi par un ou deux mois de trente et un jours, comme c'est le cas de juin et de novembre. Dans ce cas, le nombre de tours des satellites 10, 11 par tour du mobile des quantièmes 1 sera égal, soit à un nombre de tours entiers plus 1/12ième de tour, soit à un nombre entier de tours plus 11/12ième de tour, suivant que les cinq dents du pignon satellite se succèdent chronologiquement comme les mois dans l'année ou comme l'inverse des mois dans l'année.According to the number of teeth of the sun gear 9, chosen by the above formula, the five teeth of the satellite gear 11 months will have to be distributed, not grouped as in the example shown, but separated by gaps equal to one or two not, according as the month of less than thirty-one days is followed by one or two months of thirty-one days, as is the case of June and November. In this case, the number of revolutions of the satellites 10, 11 per revolution of the mobile of the dates 1 will be equal, either to a number of whole revolutions more 1/12 th of a turn, or to a whole number of revolutions plus 11/12 th turn, according to which the five teeth of the satellite gear follow one another chronologically as the months in the year or as the inverse of the months in the year.

    La figure 4 illustre la position angulaire des cinq dents du pignon satellite des mois 11 à la fin d'un mois de 31 jours, ici le mois de mars. On voit qu'aucune des cinq dents du pignon satellite 11 ne se trouve dans la trajectoire du doigt de correction 3b. Par conséquent, lorsque la bascule de saut instantané 7 fera tourner les doigts 3a et 3b par l'intermédiaire de la came 4, le doigt 3b ne rencontrera pas de dent du pignon satellite 11 et seul le doigt 3a entraínera d'un pas l'anneau des quantièmes 1, amenant le "31" dans le guichet 13.Figure 4 illustrates the angular position of the five teeth of the satellite gear of the month 11 at the end of a month of 31 days, here the month of March. We see that none of the five teeth of the pinion satellite 11 is in the trajectory correction finger 3b. Therefore, when the rocker instant jump 7 will turn the fingers 3a and 3b by through the cam 4, the finger 3b will not meet tooth of the pinion satellite 11 and only the finger 3a will cause step the date ring 1, bringing the "31" into the counter 13.
