Definitions
- the present invention relates to a mobile watch, wheel, pinion or ring gear intended to be incorporated in a cog or kinematic chain and therefore cooperating with at least one other mobile or gear, this watch mobile to allow to eliminate any play between its teeth and that of the other mobile with which it meshes.
- This invention therefore relates to a watchmaker mobile game catching.
- the document US 2808033 discloses a backlash gear comprising a first gear wheel secured to an axis and a second gear, of the same diameter as the first gear, integral with a tube.
- the axis of the first gearwheel extends into the tube of the second gearwheel and is fixed to this tube at its free end so that the teeth of the first and second wheels are shifted.
- the axis and the tube form a torsion bar allowing the wheels to angularly shift by elastic deformation of the torsion bar.
- Such a catch-up gear has major disadvantages which are its size due to the length of the axis and the tube and the very large torque necessary to angularly offset the wheels relative to each other which induces high friction forces between this game-catching gear and the gear with which it meshes which can lead to high energy losses and poor performance of the kinematic chain thus produced.
- the object of the present invention is to provide a watch-making mobile with catch-up clearance which is very compact, especially of very small thickness, and which is monobloc to facilitate its incorporation into a mechanism.
- Another object of the present invention is to provide a watchmaking mobile with backlash in which the torque necessary to move the two toothed wheels is low so as not to affect the efficiency of a transmission chain comprising such a mobile game catch-up
- Another goal is to make a mobile watchmaker to catch up with a game of low weight.
- the subject of the present invention is a watchmaking mobile device with clearance adjustment that obviates the abovementioned disadvantages, consisting of a one-piece assembly comprising a hub; a first serge serrated rigidly connected to the hub; a second serge serrated connected to the hub by second elastically deformable arms allowing angular displacement of the second serge relative to the first serge.
- the first embodiment of the watchmaking mobile with catching up game illustrated with the Figures 1 to 4 consists of a first element 1 ( Fig. 3 ) having a first toothed serge 1.1 a first hub 1.2 and first rigid arms 1.3 rigidly connecting the first toothed serge 1.1 to the first hub 1.2 and a second element 2 having a second tooth serge 2.1, a second hub 2.2. and second resiliently deformable arms 2.3 connecting the second hub 2.2 to the second serge 2.1.
- At least one of the hubs 1.2, 2.2 is slightly thicker than the serge and the corresponding arms so that when the two elements 1 and 2 are superimposed and secured by their hubs 1.2, 2.2 the arms 1.3, 2.3 and the serges 1.1, 2.1 of these two elements 1, 2 do not touch but are separated by a game that can be very small of the order of a few thousandths, or hundredths, millimeters, the thickness of the serges 1.2 and 2.1 being of the order of a few hundredths of a millimeter, for example 10, 15 or 20 hundredths of a millimeter.
- first and second elements 1, 2 can of course be secured to one another by any other means including mechanical clamping means.
- the number of teeth of the first serge 1.1 is preferably identical to the number of teeth of the second serge 2.1, the pitch of these two teeth are also preferably identical, against the shape of the teeth of the first serge 1.1 can be indifferently identical or different from the shape of the teeth of the second serge 2.1.
- the arms 1.2 of the first element are rigid, not elastically deformable, and their dimensioning is provided according to the torque that mobile watch must be able to transmit.
- These first rigid arms can be replaced by any rigid connection, for example a board.
- This first element 1 of the watchmaking mobile device with play catching of this first embodiment further comprises in its center and connected to its first hub 1.2 a pinch fixing device 1.4 for fixing the watchmaker to play catch on an axis.
- the first hub can be glued to an axis or to a metal part enabling the assembly to be driven on an axis.
- the second element 2 further comprises rigid abutment arms 2.4 extending radially from its second hub 2.2 to the second serge 2.1, the free ends of which are situated between abutments 2.5 that comprise the inner periphery of the second serge.
- These stop arms 2.4 and these stops 2.5 limit the amplitude of the angular displacement that the second serge 2.1 may perform relative to the second hub to prevent the elastic arms 2.3 of the second element 2 from accidentally breaking during handling or shock .
- the first element 1 and the second element 2 are made from a silicon wafer for example by etching according to the DRIE (Deep Reactive-ion-etching) method and the assembly of the first and second elements. is by fusion bonding of their respective hubs 1.2, 2.2 on top of one another.
- DRIE Deep Reactive-ion-etching
- the attachment of the first element 1 to the second element 2 is such that the toothing of the second serge 2.1 is angularly offset relative to the teeth of the first serge 1.1, whereas the second elastic arms 2.3 of the second element are the state of rest, not elastically deformed.
- the offset of the teeth of the first serge 1.1 and the second serge 2.1 is such that regardless of the distance between the watch mobile gaming catch-up and the mobile with which it meshes and regardless of its position .angular a tooth of the mobile with which it meshes is pinched between two teeth of the mobile watch with catch-up clearance.
- the mobile watchmaker play catch is monobloc, very thin and therefore space-saving particularly in height or thickness.
- this mobile watchmaker with catch-up game avoids any game with other mobiles with which it meshes.
- it is easy to control the low spring stiffness of the second elastically deformable arms which minimizes the energy consumption of the train comprising this mobile watch while maintaining a small footprint.
- the torque between the two sets 1 and 2 can be reduced just to its value necessary to ensure the play catchup without more, so that the losses are reduced to a minimum.
- the figure 10 illustrates for a watch making mobile watch this first embodiment the torque consumed compared to the available torque.
- the energy consumption as a percentage of the available torque as a function of the angular stiffness of the second elastic arms 2.3, connecting the two toothed serges does not exceed 10% of the torque transmitted for an angular stiffness of 400 ⁇ Nm / ° which is weak and negligible.
- the angular stiffness of the second elastic arms 2.3 is between 50 and 300 ⁇ Nm / ° preferably about 200 ⁇ Nm / °. This can be obtained during manufacture by calculating the thickness, the length and the width of the second elastic arms 2.3.
- the first serrated serge 1 has the same number of teeth as the second serrated serge 2 and these teeth are of identical shape.
- the number of teeth of the first serge 1 may be different from that of the second serge 2 as the shape of the teeth of said serrations 1, 2 may be different.
- the number and shape of the teeth of the two toothed serges are identical and the angular offset of these two serrations 1, 2 is at most equal to half a step of said teeth of these serges 1, 2.
- the figure 5 illustrates a variant of the watchmaking mobile device with catch-up of the first embodiment described with reference to the Figures 1 to 4 in which the second element 2 comprises a second toothed serge 2.1 and a second hub 2.2.
- the connection between this second serge 2.1 and the second hub 2.2 is here with the aid of a second flexible spiral elastic arm 2.6 which may have one or more turns and whose ends have come from one piece with the other.
- second serge 2.1 and the other with the second hub 2.2., the second flexible spiral elastic arm thus allows, once the second hub 2.2 secured to the first hub 1.3 of the watchmaking mobile take-up play an angular displacement of the second serge 2.1 by report to the first serge 1.1.
- the second element 2 comprises a plurality of flexible second flexible spiral arms 2.7 connecting the second serge 2.1 to the second hub 2.2.
- the second element 2 comprises second resilient flexible arms, here three, curved 2.8 connecting the second serge 2.1 to the second hub 2.2.
- FIGS. Figures 1 to 4 illustrate a second embodiment of the watchmaking mobile with play catching practically identical to that illustrated in FIGS. Figures 1 to 4 but obtained by a different manufacturing process.
- the watchmaking mobile with backlash is obtained by deep-etching etching (DRIE) machining of a composite wafer plate comprising a layer of silicon oxide between two silicon layers. .
- This pellet is etched from each of its faces to form by DRIE engraving of its first face the first serge 1.1, the first hub 1.2 and the rigid arms 1.3 and the attachment formation 1.4.
- DRIE engraving of its second face one forms the second serge 2.1, the second hub 2.2. and the second elastic arms 2.3.

Différents types d'engrenage à rattrapage de jeu sont connus. Le document
Un tel engrenage à rattrapage de jeu présente des inconvénients majeurs qui sont, son encombrement dû à la longueur de l'axe et du tube et le couple très important nécessaire pour décaler angulairement les roues l'une par rapport à l'autre ce qui induit des forces de frottements élevées entre cet engrenage à rattrapage de jeu et l'engrenage avec lequel il engrène ce qui peut conduire à des pertes d'énergie élevées et un mauvais rendement de la chaîne cinématique ainsi réalisée.Such a catch-up gear has major disadvantages which are its size due to the length of the axis and the tube and the very large torque necessary to angularly offset the wheels relative to each other which induces high friction forces between this game-catching gear and the gear with which it meshes which can lead to high energy losses and poor performance of the kinematic chain thus produced.

La première forme d'exécution du mobile horloger à rattrapage de jeu illustrée aux
Au moins un des moyeux 1.2, 2.2 est légèrement plus épais que la serge et les bras correspondants de sorte que lorsque les deux éléments 1 et 2 sont superposés et solidarisés par leurs moyeux 1.2, 2.2 les bras 1.3, 2.3 et les serges 1.1, 2.1 de ces deux éléments 1, 2 ne se touchent pas mais sont séparés par un jeu qui peut être très faible de l'ordre de quelques millièmes, voir centièmes, de millimètres, l'épaisseur des serges 1.2 et 2.1 étant de l'ordre de quelques centièmes de millimètres, par exemple 10, 15 ou 20 centièmes de millimètres.At least one of the hubs 1.2, 2.2 is slightly thicker than the serge and the corresponding arms so that when the two
Suivant les matériaux utilisés pour la réalisation des premier et second éléments 1, 2 leur assemblage se fait par collage, soudure ou fusionnement (fusion bonding) de leurs moyeux 1.2, 2.2 l'un contre l'autre.According to the materials used for producing the first and
Ces premier et second éléments 1, 2 peuvent bien entendu être rendu solidaire l'un de l'autre par tout autre moyen notamment des moyens de serrage mécanique.These first and
Le nombre de dents de la première serge 1.1 est de préférence identique au nombre de dents de la seconde serge 2.1, les pas de ces deux dentures sont également de préférence identiques, par contre la forme des dents de la première serge 1.1 peut être indifféremment identique ou différente de la forme des dents de la seconde serge 2.1.The number of teeth of the first serge 1.1 is preferably identical to the number of teeth of the second serge 2.1, the pitch of these two teeth are also preferably identical, against the shape of the teeth of the first serge 1.1 can be indifferently identical or different from the shape of the teeth of the second serge 2.1.
Les bras 1.2 du premier élément sont rigides, non déformables élastiquement, et leur dimensionnement est prévu en fonction du couple que ce mobile horloger doit pouvoir transmettre. Ces premiers bras rigides peuvent être remplacés par toute liaison rigide, par exemple une planche.The arms 1.2 of the first element are rigid, not elastically deformable, and their dimensioning is provided according to the torque that mobile watch must be able to transmit. These first rigid arms can be replaced by any rigid connection, for example a board.
Ce premier élément 1 du mobile horloger à rattrapage de jeu de cette première forme d'exécution comporte encore en son centre et relié à son premier moyeu 1.2 un dispositif de fixation par pincement 1.4 pour fixer le mobile horloger à rattrapage de jeu sur un axe.This
Dans une variante le premier moyeu peut être collé sur un axe ou sur une pièce métallique permettant le chassage de l'ensemble sur un axe.In a variant, the first hub can be glued to an axis or to a metal part enabling the assembly to be driven on an axis.
Le second élément 2 comporte encore des bras de butée 2.4 rigides s'étendant radialement de son second moyeu 2.2 vers la seconde serge 2.1 dont les extrémités libres sont situées entre des butées 2.5 que comporte la périphérie interne de la seconde serge. Ces bras de butée 2.4 et ces butées 2.5 limitent l'amplitude du déplacement angulaire que la seconde serge 2.1 peut effectuer par rapport au second moyeu pour éviter que les bras élastiques 2.3 de ce second élément 2 ne se cassent accidentellement lors de manipulations ou de chocs.The
De préférence le premier élément 1 et le second élément 2 sont réalisés à partir d'une plaque (Wafer) de silicium par exemple par gravure selon le procédé DRIE (Deep reactive-ion-etching) et l'assemblage du premier et second éléments 1.2 se fait par soudage (fusion bonding) de leurs moyeux respectifs 1.2, 2.2 l'un sur l'autre.Preferably the
La fixation du premier élément 1 sur le second élément 2 se fait de manière à ce que la denture de la seconde serge 2.1 soit décalée angulairement par rapport à la denture de la première serge 1.1 alors que les seconds bras élastiques 2.3 du second élément sont à l'état de repos, non déformés élastiquement. Le décalage des dentures de la première serge 1.1 et de la seconde serge 2.1 est tel que quel que soit l'entraxe entre le mobile horloger à rattrapage de jeu et le mobile avec lequel il engrène et quelle que soit sa position .angulaire une dent du mobile avec lequel il engrène soit pincée entre deux dents du mobile horloger à rattrapage de jeu.The attachment of the
Une fois les deux ensembles 1, 2 assemblés le mobile horloger à rattrapage de jeu est monobloc, très mince et donc peu encombrant particulièrement en hauteur ou épaisseur. Lorsqu'il est réalisé en silicium il est extrêmement précis du fait des nouvelles techniques d'usinage et son matériau est sans fatigue. En fonction, ce mobile horloger à rattrapage de jeu évite tout jeu avec d'autres mobiles avec lesquels il engrène. En effet par cette réalisation il est aisé de maîtriser des faibles raideurs de ressort des seconds bras élastiquement déformables ce qui minimise la consommation d'énergie du rouage comportant ce mobile horloger tout en maintenant un faible encombrement. En fait en ajustant les caractéristiques géométriques des bras élastiques 2.3 le couple entre les deux ensembles 1 et 2 peut être réduit juste à sa valeur nécessaire pour assurer le rattrapage de jeu sans plus, de sorte que les pertes sont réduites au minimum.Once the two assemblies 1, 2 assembled the mobile watchmaker play catch is monobloc, very thin and therefore space-saving particularly in height or thickness. When made of silicon it is extremely accurate due to new machining techniques and its material is fatigue-free. In function, this mobile watchmaker with catch-up game avoids any game with other mobiles with which it meshes. Indeed by this embodiment it is easy to control the low spring stiffness of the second elastically deformable arms which minimizes the energy consumption of the train comprising this mobile watch while maintaining a small footprint. In fact by adjusting the geometric characteristics of the elastic arms 2.3 the torque between the two
La
Avec les techniques d'usinage du silicium on obtient un très bon état de surface du mobile et notamment des dentures des deux serges 1 et 2 et une grande liberté de design notamment des dentures. Au repos il n'y a pas de préarmage des seconds bras élastiques 2.3. De plus ce mobile horloger peut être réalisé dans de très petites dimensions.With silicon machining techniques we obtain a very good surface of the mobile and in particular the teeth of the two
Dans cette première forme d'exécution du mobile horloger à rattrapage de jeu la première serge dentée 1 comporte le même nombre de dents que la seconde serge dentée 2 et ces dents sont de forme identique. Toutefois dans des variantes le nombre de dents de la première serge dentée 1 peut être différent de celui de la seconde serge dentée 2 de même que la forme des dents desdites serges dentées 1, 2 peut être différente.In this first embodiment of the time-compensating watchmaker, the first
Ce qui importe c'est qu'en fonctionnant, le mobile horloger à rattrapage de jeu étant en prise avec un engrenage, au moins une dent de cet engrenage soit en permanence pincée entre deux dents du mobile horloger à rattrapage de jeu quelle que soit la position angulaire de ce mobile horloger et l'entraxe des deux mobiles.What is important is that, by operating, the mobile watchmaker with play catching being engaged with a gear, at least one tooth of this gear is permanently pinched between two teeth of the mobile watchmaker with catch-up regardless of the angular position of this mobile watch and the distance between the two mobiles.
De préférence le nombre et la forme des dents des deux serges dentées sont identiques et le décalage angulaire de ces deux serges 1, 2 est au plus égal à un demi pas desdites dentures de ces serges 1, 2.Preferably, the number and shape of the teeth of the two toothed serges are identical and the angular offset of these two

Dans cette forme d'exécution le mobile horloger à rattrapage de jeu est obtenu par l'usinage par gravage DRIE (deep reactive-ion etching) d'une plaque (Wafer) composite comportant une couche d'oxyde de silicium entre deux couches de silicium. Cette pastille est gravée à partir de chacune de ses faces pour former par gravage DRIE de sa première face la première serge 1.1, le premier moyeu 1.2 et les bras rigides 1.3 ainsi que la formation de fixation 1.4. Puis par gravage DRIE de sa seconde face on forme la seconde serge 2.1, le second moyeu 2.2. et les seconds bras élastiques 2.3. Les bras de butée 2.4 et les butées 2.5 sont également obtenues par cette seconde gravure.In this embodiment, the watchmaking mobile with backlash is obtained by deep-etching etching (DRIE) machining of a composite wafer plate comprising a layer of silicon oxide between two silicon layers. . This pellet is etched from each of its faces to form by DRIE engraving of its first face the first serge 1.1, the first hub 1.2 and the rigid arms 1.3 and the attachment formation 1.4. Then by DRIE engraving of its second face one forms the second serge 2.1, the second hub 2.2. and the second elastic arms 2.3. The stop arms 2.4 and the abutments 2.5 are also obtained by this second etching.
Ensuite la couche médiane d'oxyde de silicium est éliminée partout sauf entre les deux moyeux 1.2 et 2.2 qui restent ainsi solidaires l'un de l'autre, la structure sandwich silicium- oxyde de silicium- silicium étant conservée.Then the middle layer of silicon oxide is removed everywhere except between the two hubs 1.2 and 2.2 which thus remain integral with each other, the silicon-silicon oxide-silicon sandwich structure being retained.
Dans une variante le mobile horloger à rattrapage de jeu peut se composer d'un sandwich silicium - métal - silicium par utilisation des techniques DRIE et LIGA combinés.In a variant, the watchmaking mobile device with a backlash may consist of a silicon - metal - silicon sandwich using the combined DRIE and LIGA techniques.
Le mobile horloger à rattrapage de jeu ainsi obtenu est monobloc, réalisé à partir d'une seule plaque (wafer) composite, et présente tous les avantages énumérés, en référence à la première forme d'exécution du mobile horloger.The watchmaking mobile game retrofit thus obtained is monobloc, made from a single plate (wafer) composite, and has all the advantages listed, with reference to the first embodiment of the watchmaker.
Il est évident que dans cette seconde forme d'exécution la forme des seconds bras élastiques 2.3 pourrait également être en forme de spirale ou incurvés comme illustré aux
Comme on peut s'en rendre compte de ce qui précède le mobile horloger à rattrapage de jeu comporte une première serge dentée 1.1 et une seconde serge dentée 2.1 superposées, de préférence de même diamètre et présentant de préférence le même nombre de dents. La première serge dentée 1.1 est reliée à un moyeu 1.2, 2.2 du mobile par des bras rigides 1.3. La seconde serge dentée 2.1 est elle reliée au moyeu 1.2, 2.2. du mobile par des seconds bras déformables élastiquement 2.3.As can be appreciated from the foregoing, the watch-making mobile watch has a first serrated serge 1.1 and a second serrated serge 2.1 superimposed, preferably of the same diameter and preferably having the same number of teeth. The first toothed serge 1.1 is connected to a hub 1.2, 2.2 of the mobile by rigid arms 1.3. The second toothed serge 2.1 is connected to the hub 1.2, 2.2. mobile by second elastically deformable arms 2.3.
Dans tous les cas le mobile est considéré comme étant monobloc car il est soit obtenu par gravage à partir des deux côtés d'une plaque sandwich silicium-oxyde de silicium - silicium soit obtenu par soudage (fusion bonding) au niveau des premier et second moyeux des éléments 1, 2, soit à partir d'une plaque composite silicium - métal - silicium usinée selon les procédés DRIE et LIGA; la pièce finale étant monobloc.In all cases the mobile is considered to be monobloc because it is either obtained by etching from both sides of a silicon-silicon oxide-silicon sandwich plate or obtained by fusion bonding at the first and second hubs.
