Description

Domaine de l'inventionField of the invention

L'invention concerne une roue anti-choc d'horlogerie pour l'entraƮnement d'un composant prƩsentant un balourd non nul par rapport Ơ un axe de pivotement de ladite roue, laquelle roue comporte, d'une part un arbre pour son guidage en pivotement autour dudit axe de pivotement, et d'autre part des moyens d'entraƮnement agencƩs ou rapportƩs sur un flasque que comporte ladite roue, ladite roue comportant au moins un ƩlƩment flexible entre ledit arbre et ledit flasque.The invention relates to a clock shock wheel for driving a component having a non-zero imbalance with respect to a pivot axis of said wheel, which wheel comprises, firstly a shaft for its guidance in pivoting about said pivot axis, and secondly driving means arranged or reported on a flange that includes said wheel, said wheel having at least one flexible element between said shaft and said flange.

L'invention concerne encore un mouvement horloger comportant une telle roue portant un dit composant prƩsentant un balourd non nul par rapport Ơ un axe de pivotement de ladite roue.The invention also relates to a watch movement comprising such a wheel bearing a said component having a non-zero unbalance with respect to a pivot axis of said wheel.

L'invention concerne encore une montre comportant au moins un tel mouvement horloger.The invention also relates to a watch comprising at least one such watch movement.

L'invention concerne le domaine de la protection des montres contre les effets des chocs, en particulier quand elles comportent des composants mobiles avec un balourd important risquant d'endommager un ƩlƩment plus fragile de la chaƮne cinƩmatique lors d'un choc.The invention relates to the field of the protection of watches against the effects of shocks, especially when they include moving components with a large imbalance that may damage a more fragile element of the drive train during an impact.

ArriĆØre-plan de l'inventionBackground of the invention

L'utilisation de technologies permettant d'utiliser des balourds d'aiguilles plus importants implique de nouveaux problĆØmes :

  • glissement des aiguilles sur les tubes ;
  • casse des rouages, ou/et des rotors de moteurs en versions Ć©lectriques, lors d'un choc Ć  5000g.
The use of technologies to use larger needle imbalances involves new problems:
  • slipping of the needles on the tubes;
  • breaks the wheels, or / and motor rotors in electric versions, during a shock at 5000g.

Ce dernier point est de loin le plus critique. Sur certains calibres existants, ce genre de casse peut se produire lors d'un choc Ć  5000g, tel qu'une chute accidentelle depuis la hauteur de l'utilisateur.This last point is by far the most critical. On some existing calibres, this kind of breakage can occur during a shock at 5000g, such as an accidental fall from the height of the user.

La casse ne permet plus Ơ la montre de fonctionner, ce qui produit un fort impact sur la qualitƩ perƧue par l'utilisateur.The case no longer allows the watch to operate, which has a strong impact on the quality perceived by the user.

L'invention vise Ć  empĆŖcher la casse des rouages ou/et du rotor en absorbant l'Ć©nergie du choc, sans impacter le design des aiguilles. En effet, si on peut rajouter une contre-masse aux aiguilles afin de rĆ©duire leur balourd, et ainsi rĆ©duire le couple exercĆ© lors d'un choc important, ce type de solution altĆØre l'aspect des aiguilles souhaitĆ© par les manufactures.The invention aims to prevent breakage of the wheels and / or the rotor by absorbing the energy of the shock, without impacting the design of the needles. Indeed, if we can add a counterweight to the needles to reduce their unbalance, and thus reduce the torque exerted during a major shock, this type of solution alters the appearance of the hands desired by the manufactures.

L'absorption de l'Ć©nergie du choc est nĆ©cessaire pour permettre d'utiliser des aiguilles avec des balourds importants, encore plus courantes avec la tendance actuelle Ć  l'augmentation du diamĆØtre des montres.The absorption of shock energy is necessary to allow the use of needles with significant unbalance, even more common with the current trend to increase the diameter of watches.

Le dispositif comporte encore une rondelle prĆ©sentant un trou et fixĆ©e sur l'axe de maniĆØre Ć  ce que la piĆØce soit situĆ©e entre la butĆ©e et la rondelle. La seule possibilitĆ© de protection contre les contraintes externes est fournie par l'Ć©lasticitĆ© du silicium au niveau du pincement de l'arbre.The document EP 1 705 533 in the name of PATEK PHILIPPE SA describes an assembly of a silicon part on an axis having a bearing adjacent an axial abutment. The piece has a passage cooperating with the scope. The device further comprises a washer having a hole and fixed on the axis so that the piece is located between the stop and the washer.

RƩsumƩ de l'inventionSummary of the invention

Le principe de base de l'invention est d'absorber le choc en permettant une torsion Ć©lastique au niveau d'un composant du rouage, et, tout particuliĆØrement, de la roue de centre. Cette torsion est rĆ©alisĆ©e par un glissement entre l'arbre 2 d'arbre de centre et le flasque 8. Un Ć©lĆ©ment Ć©lastique permet d'absorber le choc. Le glissement tube/planche permet de dissiper un peu d'Ć©nergie en frottement. L'Ć©lĆ©ment Ć©lastique permet de modifier l'amplitude et la durĆ©e du choc (amplitude plus faible et durĆ©e plus longue).The basic principle of the invention is to absorb the shock by allowing elastic torsion at a component of the train, and particularly the center wheel. This torsion is achieved by sliding between the shaft 2 of the center shaft and the flange 8. An elastic element makes it possible to absorb the impact. The sliding tube / board allows to dissipate some energy in friction. The elastic element makes it possible to modify the amplitude and duration of the shock (lower amplitude and longer duration).

Description dƩtaillƩe des modes de rƩalisation prƩfƩrƩsDetailed Description of the Preferred Embodiments

L'invention se propose d'amƩliorer la protection des montres contre les effets des chocs. L'effet d'un choc important sur un composant mobile avec un balourd important risque d'endommager les ƩlƩments les plus fragiles de la chaƮne cinƩmatique.The invention proposes to improve the protection of watches against the effects of shocks. The effect of a large impact on a moving component with a large unbalance may damage the most fragile elements of the driveline.

A cet effet, l'invention concerne une roue 1 anti-choc d'horlogerie pour l'entraƮnement d'un composant 4 prƩsentant un balourd B non nul par rapport Ơ un axe de pivotement D de la roue 1.For this purpose, the invention relates to a watch shock wheel 1 for driving a component 4 having a non-zero unbalance B relative to a pivot axis D of the wheel 1.

Cette roue 1 comporte, d'une part un arbre 2 pour son guidage en pivotement autour de l'axe de pivotement D, et d'autre part des moyens d'entraĆ®nement 7 agencĆ©s ou rapportĆ©s sur un flasque 8 que comporte la roue 1. Ces moyens d'entraĆ®nement 7 peuvent ĆŖtre un secteur dentĆ©, une piste pour courroie ou chaĆ®ne ou similaire, ou autre.This wheel 1 comprises, on the one hand a shaft 2 for its guidance in pivoting about the pivot axis D, and on the other hand drive means 7 arranged or reported on a flange 8 that includes the wheel 1. These drive means 7 may be a toothed sector, a belt track or chain or the like, or other.

La roue 1 comporte au moins un ƩlƩment flexible 9 entre l'arbre 2 et le flasque 8, pour absorber l'impact dƻ au choc, et amortir l'effet sur les autres composants du mouvement horloger 100, dans lequel est incorporƩe la roue 1 selon l'invention.The wheel 1 comprises at least one flexible element 9 between the shaft 2 and the flange 8, to absorb the impact due to impact, and dampen the effect on the other components of the watch movement 100, in which the wheel 1 is incorporated. according to the invention.

Selon l'invention, ce flasque 8 comporte une portĆ©e cylindrique 81 coopĆ©rant en appui de centrage avec une portĆ©e cylindrique complĆ©mentaire 21 que comporte l'arbre 2 pour assurer la parfaite concentricitĆ© des moyens d'entraĆ®nement 7 avec l'arbre 2. La gĆ©omĆ©trie est ainsi toujours parfaitement assurĆ©e, ainsi que la prĆ©cision de la transmission de mouvement. Cette disposition assure l'absence de tout faux rond, ainsi que de toute vibration parasite du fait d'un jeu extrĆŖmement rĆ©duit.According to the invention, this flange 8 comprises a cylindrical bearing surface 81 cooperating in centering bearing with a complementary cylindrical bearing surface 21 that comprises the shaft 2 to ensure the perfect concentricity of the drive means 7 with the shaft 2. The geometry is thus always perfectly assured, as well as the precision of the motion transmission. This arrangement ensures the absence of any false round, as well as any parasitic vibration due to an extremely small game.

Les figures illustrent plusieurs modes de rƩalisation de l'invention, nullement limitatifs.The figures illustrate several embodiments of the invention, in no way limiting.

Parmi ces modes illustrƩs, les trois premiers modes, illustrƩs aux figures 1 Ơ 34, concernent une variante avantageuse de l'invention, dans laquelle l'ƩlƩment flexible 9 est un ƩlƩment interchangeable distinct de l'arbre 2 et du flasque 8. La rƩsilience de cet ƩlƩment flexible est choisie en fonction de la valeur maximale admissible du balourd B.Among these illustrated modes, the first three modes, illustrated in Figures 1 to 34 relate to an advantageous variant of the invention, in which the flexible element 9 is an interchangeable element distinct from the shaft 2 and the flange 8. The The resilience of this flexible element is chosen according to the maximum permissible value of the unbalance B.

Ainsi, il est possible de concevoir, pour un mĆŖme couple arbre 2-flasque 8, qui dĆ©termine les interfaces gĆ©omĆ©triques avec le reste du mouvement, une sĆ©rie d'Ć©lĆ©ments flexibles 9 de gĆ©omĆ©trie similaire, mais de capacitĆ©s d'amortissement diffĆ©rentes, permettant d'adapter au mieux la roue anti-choc 1 au contexte d'utilisation, et en particulier Ć  la valeur du balourd B, et aussi au niveau de chocs prĆ©visible, qui dĆ©pend de l'utilisation ou de la destination de la montre, par exemple pour des utilisateurs travaillant en milieu vibratoire contraignant, comme les travaux publics, ou pour des utilisateurs du milieu sportif, militaire, ou similaire. Comme on le verra plus loin, l'assemblage de la roue 1 est conƧu pour ĆŖtre trĆØs simple, et il est donc possible de personnaliser une montre Ć  ses conditions d'utilisation en choisissant l'Ć©lĆ©ment flexible 9 adĆ©quat.Thus, it is possible to design, for the same pair of 2-flange shaft 8, which determines the geometrical interfaces with the rest of the movement, a series of flexible elements 9 of similar geometry, but of different damping capacities, allowing to best adapt the impact wheel 1 to the context of use, and in particular to the value of the unbalance B, and also the predictable shock level, which depends on the use or the destination of the watch, for example for users working in a constricting vibratory environment, such as public works, or for users of the sports, military, or similar environment. As will be seen below, the assembly of the wheel 1 is designed to be very simple, and it is therefore possible to customize a watch to its conditions of use by choosing the appropriate flexible element 9.

DiffĆ©rentes versions de montage, non limitatives sont prĆ©sentĆ©es ici. En particulier, l'Ć©lĆ©ment flexible 9 peut ĆŖtre montĆ© :

  • soit prisonnier entre le flasque 8 et une rondelle de blocage 20 chassĆ©e ou sertie sur l'arbre 2,
  • soit clipĆ© de part et d'autre d'une zone d'assemblage de la portĆ©e cylindrique 81 avec la portĆ©e cylindrique complĆ©mentaire 21.
  • soit clipĆ© au niveau d'une zone d'assemblage de la portĆ©e cylindrique 81 et de la portĆ©e cylindrique complĆ©mentaire 21.
Different mounting versions, not limiting, are presented here. In particular, the flexible element 9 can be mounted:
  • is trapped between the flange 8 and a lock washer 20 driven or crimped on the shaft 2,
  • is clipped on either side of an assembly area of the cylindrical seat 81 with the complementary cylindrical bearing surface 21.
  • is clipped at an assembly area of the cylindrical bearing surface 81 and the complementary cylindrical bearing surface 21.

Dans le premier et le deuxiĆØme mode de rĆ©alisation, les Ć©lĆ©ments flexibles 9 sont des joints circulaires sensiblement plats, et sont coincĆ©s entre le flasque 8 et l'arbre 2. Le flasque 8 pivote sur l'arbre 2. Une rondelle en appui sur l'arbre 2 et rivetĆ©e sur celui-ci rĆ©alise un arrĆŖt axial du flasque 8. Les joints permettent de transmettre le couple entre le flasque 8 et l'arbre 2. Lors d'un choc, ces joints se dĆ©forment et absorbent donc une partie de l'Ć©nergie du choc. Quand le choc est terminĆ©, le flasque 8 revient en position initiale par rapport Ć  l'arbre 2.In the first and second embodiments, the flexible elements 9 are substantially flat circular seals, and are wedged between the flange 8 and the shaft 2. The flange 8 pivots on the shaft 2. A washer resting on the 2 and riveted on it makes an axial stop of the flange 8. The seals allow to transmit the torque between the flange 8 and the shaft 2. During an impact, these joints deform and absorb some of the energy of the shock. When the shock is over, the flange 8 returns to its initial position relative to the shaft 2.

Dans le cas particulier de l'application de l'invention Ơ une roue de centre 1 porteuse d'une aiguille 5, le choc est absorbƩ directement au niveau de la roue de centre 1. C'est-Ơ-dire que l'Ʃnergie du choc, exercƩ par le balourd d'aiguille, est absorbƩe au plus tƓt dans la chaƮne de transmission du couple.In the particular case of the application of the invention to a center wheel 1 carrying a needle 5, the shock is absorbed directly at the center wheel 1. That is to say that the energy shock, exerted by the unbalance needle, is absorbed at the earliest in the transmission chain torque.

Cela permet d'Ć©viter la casse des Ć©ventuels rouages et rotors en matiĆØre plastique avec de petits pivots, que peut comporter un mouvement 100. Les avantages de ces composants plastiques sont le coĆ»t rĆ©duit, la prĆ©-lubrification, le faible niveau de frottement au niveau des pivots. Le fait de pouvoir conserver, dans un mouvement, de tels composants Ć©vite l'utilisation de composants mĆ©talliques, synonyme d'augmentation de coĆ»ts et de problĆØmes de faisabilitĆ© (notamment pour le rotor quand il s'agit d'un mouvement Ć©lectrique ou quartz). Absorber le choc Ć©vite Ć©galement que les aiguilles ne glissent sur leur tube d'arbre 2.This avoids the breakage of any workings and rotors made of plastic with small pivots, which may include a movement 100. The advantages of these plastic components are the reduced cost, the pre-lubrication, the low level of friction at the pivots. The fact of being able to keep, in a movement, such components avoids the use of metal components, synonymous with increased costs and problems of feasibility (especially for the rotor when it is an electric movement or quartz) . Absorbing the shock also prevents the needles from slipping on their shaft tube 2.

Dans le premier mode de rĆ©alisation illustrĆ© aux figures 1 Ć  15, la roue anti-chocs 1, illustrĆ©e sous forme d'une roue des minutes, comporte un flasque 8 dentĆ© avec une denture 7, centrĆ© sur un arbre 2, et fixĆ© Ć  cet arbre 2 par un mĆ©canisme Ć  baĆÆonnette. Ce flasque 8 est liĆ© en pivotement Ć  cet arbre 2 par un Ć©lĆ©ment flexible 9 dĆ©formable en cas de choc, de type Ć©lastomĆØre ou similaire, cet Ć©lĆ©ment flexible 9 est plaquĆ© sur une surface supĆ©rieure 8A du flasque 8, et clipĆ© sous une surface infĆ©rieure 8B de ce flasque 8.In the first embodiment illustrated in Figures 1 to 15 , the anti-shock wheel 1, illustrated in the form of a minute wheel, comprises a toothed flange 8 with a toothing 7, centered on a shaft 2, and fixed to this shaft 2 by a bayonet mechanism. This flange 8 is pivotally connected to this shaft 2 by a flexible element 9 which can be deformed in the event of an impact, of elastomer type or the like, this flexible element 9 is pressed onto an upper surface 8A of the flange 8 and clipped under a lower surface 8B of this flange 8.

Cet Ć©lastomĆØre a une duretĆ© voisine de 50 Shore A. Un copolymĆØre de type dit Ā« NBR Ā», ou butadiĆØne-acrylonitrile, convient particuliĆØrement. D'autres Ć©lastomĆØres de duretĆ© voisine peuvent Ć©galement convenir.This elastomer has a hardness close to 50 Shore A. A copolymer of the type called "NBR", or butadiene-acrylonitrile, is particularly suitable. Other elastomers of similar hardness may also be suitable.

La figure 8 montre, sur l'arbre 2, contiguƫ Ơ une portƩe cylindrique 21 prƩvue pour le centrage du flasque 8, une gorge radiale 25 prƩvue pour l'immobilisation axiale du flasque 8.The figure 8 shows, on the shaft 2, contiguous to a cylindrical bearing surface 21 provided for centering the flange 8, a radial groove 25 provided for the axial immobilization of the flange 8.

Dans cette rĆ©alisation, l'Ć©lĆ©ment flexible 9 comporte des protubĆ©rances 93 qui sont agencĆ©es pour, en fonctionnement normal, transmettre un couple d'entraĆ®nement entre l'arbre 2 et le flasque 8, et pour, lors d'un choc Ć©ventuel, absorber la torsion entre l'arbre 2 et le flasque 8, pour dissiper une partie de l'Ć©nergie du choc en frottement, pour modifier l'effet, sur les moyens d'entraĆ®nement 7, de l'amplitude et la durĆ©e du choc, en en rĆ©duisant l'amplitude et en augmentant la durĆ©e, et pour constituer des moyens de rappel Ć©lastique rappelant le flasque 8 par rapport Ć  l'arbre 2 dans une position de rĆ©alignement aprĆØs le choc.In this embodiment, the flexible element 9 comprises protuberances 93 which are arranged, in normal operation, to transmit a driving torque between the shaft 2 and the flange 8, and for, during a possible shock, to absorb the torsion between the shaft 2 and the flange 8, to dissipate a portion of the energy of the impact friction, to modify the effect on the drive means 7, the amplitude and duration of the shock, in reducing the amplitude and increasing the duration, and to constitute elastic return means reminding the flange 8 relative to the shaft 2 in a position of realignment after the shock.

Ces protubƩrances 93 sont de prƩfƩrence reliƩes l'une Ơ l'autre par un anneau 92 de l'ƩlƩment flexible 9, lequel anneau 92 est agencƩ pour venir en appui sur une surface latƩrale 8A du flasque 8.These protuberances 93 are preferably connected to one another by a ring 92 of the flexible element 9, which ring 92 is arranged to bear on a lateral surface 8A of the flange 8.

De prĆ©fĆ©rence, ces protubĆ©rances 93 sont identiques entre elles et disposĆ©es de faƧon rĆ©guliĆØre autour d'une direction axiale DA autour de laquelle s'Ć©tend l'Ć©lĆ©ment flexible 9.Preferably, these protuberances 93 are identical to one another and arranged regularly around an axial direction DA around which the flexible element 9 extends.

Le flasque 8 comporte des logements 82 de rƩception et de centrage des protubƩrances 93 de l'ƩlƩment flexible 9.The flange 8 has housing 82 for receiving and centering the protuberances 93 of the flexible element 9.

L'arbre 2 comporte aussi des logements complƩmentaires 22 de rƩception et de centrage des protubƩrances 93.The shaft 2 also comprises complementary housing 22 for receiving and centering the protuberances 93.

L'arbre 2 et le flasque 8 sont agencĆ©s de faƧon Ć  ce que, dans au moins une position angulaire de l'un par rapport Ć  l'autre quand ils sont assemblĆ©s avec la portĆ©e cylindrique 81 coopĆ©rant en appui de centrage avec la portĆ©e cylindrique complĆ©mentaire 21, les logements 82 et les logements complĆ©mentaires 22 forment deux Ć  deux des alvĆ©oles 23 pour la rĆ©ception complĆØte et complĆ©mentaire des protubĆ©rances 93 quand l'Ć©lĆ©ment flexible 9 est plaquĆ© sur le flasque 8.The shaft 2 and the flange 8 are arranged so that, in at least one angular position of the one relative to the other when they are assembled with the cylindrical bearing surface 81 cooperating in centering support with the cylindrical seat 21, the housing 82 and the complementary housing 22 form pairs of cells 23 for the complete and complementary reception of the protuberances 93 when the flexible element 9 is pressed on the flange 8.

Le flasque 8 comporte un logement 85 pour la rƩception de l'arbre 2.The flange 8 comprises a housing 85 for receiving the shaft 2.

De faƧon avantageuse, l'arbre 2 comporte une gorge 25 agencĆ©e pour recevoir, dans une premiĆØre position angulaire relative, une nervure 85 que comporte le flasque 8, quand l'arbre 2 et le flasque 8 sont assemblĆ©s avec la portĆ©e cylindrique 81 en appui de centrage avec la portĆ©e cylindrique complĆ©mentaire 21 et quand le flasque 8 est en position de butĆ©e, en appui par une surface latĆ©rale 8A du flasque 8, contre une surface d'Ć©paulement 27 de l'arbre 2. La gorge 25 autorise le pivotement en baĆÆonnette de l'arbre 2 par rapport au flasque 8 dans une au moins une deuxiĆØme position angulaire relative, dans laquelle les logements 82 et les logements complĆ©mentaires 22 sont alignĆ©s et forment deux Ć  deux des alvĆ©oles 23 pour la rĆ©ception complĆØte et complĆ©mentaire des protubĆ©rances 93 quand l'Ć©lĆ©ment flexible 9 est plaquĆ© sur le flasque 8, les protubĆ©rances 93 assurant alors l'indexation angulaire du flasque 8 par rapport Ć  l'arbre 2.Advantageously, the shaft 2 comprises a groove 25 arranged to receive, in a first relative angular position, a rib 85 that includes the flange 8, when the shaft 2 and the flange 8 are assembled with the cylindrical bearing surface 81 centering with the complementary cylindrical surface 21 and when the flange 8 is in abutment position, supported by a lateral surface 8A of the flange 8, against a shoulder surface 27 of the shaft 2. The groove 25 allows the pivoting in bayonet shaft 2 relative to the flange 8 in at least a second relative angular position, wherein the housing 82 and the complementary housing 22 are aligned and form two by two cells 23 for the complete and complementary reception of the protuberances 93 when the flexible element 9 is pressed onto the flange 8, the protuberances 93 then ensuring the angular indexing of the flange 8 with respect to the shaft 2.

La figure 9 illustre ainsi l'emmanchement, dans une premiĆØre position angulaire relative d'introduction, du flasque 8 sur l'arbre 2 dans une position d'appui en butĆ©e. La figure 10 montre le flasque 8 et l'arbre 2 coopĆ©rant dans une deuxiĆØme position angulaire, aprĆØs une rotation et un verrouillage de type baĆÆonnette, cette deuxiĆØme position angulaire correspondant Ć  une mise en concordance de logements de rĆ©ception 82 du flasque 8, et de logements de rĆ©ception complĆ©mentaire 22 de l'arbre 2, pour constituer ensemble des alvĆ©oles 23 pour le positionnement ajustĆ© de protubĆ©rances 93 que comporte l'Ć©lĆ©ment flexible 9.The figure 9 thus illustrates the fitting, in a first relative angular insertion position, of the flange 8 on the shaft 2 in a abutment bearing position. The figure 10 shows the flange 8 and the shaft 2 cooperating in a second angular position, after a rotation and a bayonet-type locking, this second angular position corresponding to a matching of reception slots 82 of the flange 8, and receiving housing complementary 22 of the shaft 2, to constitute together cells 23 for the adjusted positioning of protuberances 93 that includes the flexible element 9.

La figure 11 montre la mise en position de l'ƩlƩment flexible 9 en appui sur une surface supƩrieure 8A du flasque 8, et la mise en coopƩration de ses protubƩrances 93 avec les alvƩoles 23 de positionnement.The figure 11 shows the positioning of the flexible element 9 bearing on an upper surface 8A of the flange 8, and the cooperation of its protuberances 93 with the cells 23 of positioning.

Dans ce mode de rƩalisation, l'ƩlƩment flexible 9 comporte des pattes de clipage 94 et est montƩ clipƩ de part et d'autre de la zone d'assemblage de la portƩe cylindrique 81 et de la portƩe cylindrique complƩmentaire 21.In this embodiment, the flexible element 9 has clipping lugs 94 and is mounted clipped on either side of the assembly area of the cylindrical bearing surface 81 and the complementary cylindrical bearing surface 21.

La figure 12 montre la position atteinte aprĆØs clipage des pattes de clipage 94 que comporte l'Ć©lĆ©ment flexible, visibles aux figures 4, 6 et 7, autour du flasque en prenant appui par leur extrĆ©mitĆ© 98 sur une surface infĆ©rieure 8B du flasque 8. Les figures 13 Ć  15 illustrent un montage similaire d'une roue d'heures, l'assemblage s'effectue de la mĆŖme faƧon mais avec l'arbre 2 renversĆ©.The figure 12 shows the position reached after clip clipping tabs 94 that includes the flexible element, visible to the Figures 4, 6 and 7 around the flange being supported by their end 98 on a lower surface 8B of the flange 8. Figures 13 to 15 illustrate a similar assembly of a wheel of hours, the assembly is carried out in the same way but with the shaft 2 reversed.

Dans une rĆ©alisation particuliĆØre de ce premier mode, sur au moins une partie de son Ć©paisseur, chaque protubĆ©rance 93 est symĆ©trique par rapport Ć  un plan passant par la direction axiale DA et comporte au moins deux crĆŖtes 95 rayonnĆ©es et dirigĆ©es vers cette direction axiale DA, sĆ©parĆ©es par un creux rayonnĆ© 96 permettant d'absorber la compression de la protubĆ©rance 93 lors d'un choc. Dans ce cas particulier des figures, la protubĆ©rance 93 a un tel profil, encore dĆ©limitĆ© latĆ©ralement par des creux rayonnĆ©s 97, d'un seul cĆ“tĆ© 9A de l'Ć©lĆ©ment flexible 9, et la surface principale 91 dite supĆ©rieure, visible sur la figure 1, est destinĆ©e Ć  venir au-dessus d'une surface supĆ©rieure 8A du flasque 8, tandis que, du cĆ“tĆ© opposĆ©, la partie 9B de la protubĆ©rance 93 est sensiblement cylindrique, et constitue la surface active pour l'amortissement. La surface 99 dite infĆ©rieure de cette partie 9B est destinĆ©e Ć  sensiblement affleurer la surface infĆ©rieure 8B du flasque 8. La partie 9A permet ainsi de tenir la partie cylindrique 9B dans la bonne position. La protubĆ©rance 93 accepte une certaine dĆ©formation, notamment en vrillage, de la partie 9A par rapport Ć  la partie 9B, ce qui permet d'absorber une partie de l'Ć©nergie du choc, l'autre partie de l'Ć©nergie Ć©tant absorbĆ©e par la compression de la partie 9B.In a particular embodiment of this first embodiment, over at least part of its thickness, each protuberance 93 is symmetrical with respect to a plane passing through the axial direction DA and comprises at least two ridges 95 radiated and directed towards this axial direction DA, separated by a radially hollow 96 for absorbing the compression of the protuberance 93 during an impact. In this particular case of the figures, the protuberance 93 has such a profile, still delimited laterally by radially recessed openings 97, on one side only 9A of the flexible element 9, and the so-called upper main surface 91, visible on the figure 1 , is intended to come over an upper surface 8A of the flange 8, while on the opposite side, the portion 9B of the protuberance 93 is substantially cylindrical, and constitutes the active surface for damping. The so-called lower surface 99 of this portion 9B is intended to be substantially flush with the lower surface 8B of the flange 8. The portion 9A thus makes it possible to hold the cylindrical portion 9B in the correct position. The protuberance 93 accepts a certain deformation, in particular twisting, of the portion 9A relative to the portion 9B, which absorbs some of the impact energy, the other part of the energy being absorbed by the compression of part 9B.

Dans le deuxiĆØme mode de rĆ©alisation des figures 16 Ć  29, l'Ć©lĆ©ment flexible 9 est montĆ© prisonnier entre le flasque 8 et une rondelle de blocage 20 chassĆ©e ou sertie sur l'arbre 2.In the second embodiment of the Figures 16 to 29 , the flexible element 9 is mounted prisoner between the flange 8 and a locking washer 20 driven or crimped onto the shaft 2.

La roue des minutes 1 comporte un flasque 8 dentĆ© centrĆ© sur un arbre 2, ce flasque 8 Ć©tant liĆ© en pivotement Ć  cet arbre 2 par un Ć©lĆ©ment flexible 9 dĆ©formable en cas de choc, Ć©galement de type Ć©lastomĆØre ou similaire, cet Ć©lĆ©ment flexible 9 est plaquĆ© sur une surface supĆ©rieure 8A du flasque 8, et est maintenu, ainsi que le flasque 8, sur l'arbre 2 par une rondelle de blocage 20 chassĆ©e, ou de prĆ©fĆ©rence rivĆ©e, ou similaire, sur l'arbre. Les figures montrent une version avec une rivure 26 prĆ©parĆ©e au niveau de l'arbre 2 brut, et qui est mise en forme aprĆØs montage de la rondelle de blocage 20.The minute wheel 1 comprises a toothed flange 8 centered on a shaft 2, this flange 8 being pivotally connected to this shaft 2 by a flexible element 9 which can be deformed in the event of an impact, also of the elastomer type or the like, this flexible element 9 is plated on an upper surface 8A of the flange 8, and is maintained, as well as the flange 8, on the shaft 2 by a blocking washer 20 driven, or preferably riveted, or the like, on the shaft. The figures show a version with a rivet 26 prepared at the level of the raw shaft 2, and which is shaped after mounting of the locking washer 20.

L'arbre 2 comporte, de part et d'autre d'une portĆ©e cylindrique 21 prĆ©vue pour le centrage du flasque 8, d'une part un Ć©paulement 27 pour l'immobilisation axiale du flasque 8, et d'autre part cette rivure 26 pour l'immobilisation du flasque 8 et de la rondelle de blocage 20 aprĆØs leur mise en position;The shaft 2 comprises, on either side of a cylindrical bearing surface 21 intended for centering the flange 8, on the one hand a shoulder 27 for the axial immobilization of the flange 8, and on the other hand this rivet 26 for the immobilization of the flange 8 and the locking washer 20 after being put in position;

La figure 23 montre l'emmanchement du flasque 8 sur l'arbre 2 dans une position d'appui en butĆ©e, dans une position angulaire correspondant Ć  une mise en concordance des logements de rĆ©ception 82 du flasque 8, et des logements de rĆ©ception complĆ©mentaire 22 de l'arbre 2, pour constituer ensemble des alvĆ©oles 23 pour le positionnement ajustĆ© des protubĆ©rances 93 que comporte l'Ć©lĆ©ment flexible 9. Celui-ci prend de prĆ©fĆ©rence la forme d'un anneau 92 sur lequel sont rapportĆ©s trois bossages constituant les protubĆ©rances 93, qui peuvent ĆŖtre cylindriques ou avec un mĆ©plat radial 90 pour la coopĆ©ration avec l'arbre 2.The figure 23 shows the fitting of the flange 8 on the shaft 2 in a abutment bearing position, in an angular position corresponding to a matching of the receiving housing 82 of the flange 8, and complementary receiving housing 22 of the shaft 2, to form together cells 23 for the adjusted positioning of the protuberances 93 that comprises the flexible element 9. This preferably takes the form of a ring 92 on which are reported three bosses constituting the protuberances 93, which can be cylindrical or with a radial flat 90 for cooperation with the shaft 2.

La figure 24 montre la mise en position de l'Ć©lĆ©ment flexible 9 en appui sur une surface supĆ©rieure 8A du flasque 8, et la mise en coopĆ©ration de ses protubĆ©rances 93 avec les alvĆ©oles 23 de positionnement, et la figure 25 montre la pose de la rondelle de blocage 20 sur l'Ć©lĆ©ment flexible 9 en le comprimant sur le flasque 8, la figure 26 montrant la position finale aprĆØs sertissage de cette rondelle de blocage 20 sur l'arbre 2 par rabattage de la rivure 26.The figure 24 shows the positioning of the flexible element 9 resting on an upper surface 8A of the flange 8, and the cooperation of its protuberances 93 with the positioning cells 23, and the figure 25 shows the installation of the locking washer 20 on the flexible element 9 by compressing it on the flange 8, the figure 26 showing the final position after crimping of this lock washer 20 on the shaft 2 by folding the rivet 26.

Les figures 27 Ć  29 illustrent un montage similaire d'une roue d'heures, l'assemblage s'effectuant de la mĆŖme faƧon mais avec l'arbre 2 renversĆ©.The Figures 27 to 29 illustrate a similar assembly of a wheel of hours, the assembly being performed in the same way but with the shaft 2 reversed.

Dans le troisiĆØme mode de rĆ©alisation des figures 30 Ć  34, l'Ć©lĆ©ment flexible 9 est un ressort-fil 6 de forme sensiblement en omega, maintenu d'une part dans une gorge frontale 28 de l'arbre 2 et d'autre part dans une chambre 88 du flasque 8, dans laquelle le ressort 6 est maintenu sensiblement coplanaire au flasque 8. Ce ressort de forme 6 est placĆ© entre le flasque 8 et l'arbre 2. Le ressort 6 ne peut pas tourner sur l'arbre 2. Les branches 61 et 62 du ressort sont prĆ©chargĆ©es sur le flasque 8. Une rondelle en appui sur l'arbre 2, et rivetĆ©e sur celui-ci rĆ©alise un arrĆŖt axial du flasque 8, et permet d'emprisonner et guider le ressort 6 dans le plan du flasque 8. Lors d'un choc, les branches 61 et 62 du ressort 6 se dĆ©forment, absorbant ainsi une partie de l'Ć©nergie du choc. Quand le choc est terminĆ©, le flasque 8 revient en position initiale par rapport Ć  l'arbre 2.In the third embodiment of the Figures 30 to 34 , the flexible element 9 is a wire spring 6 of substantially omega shape, maintained firstly in a front groove 28 of the shaft 2 and secondly in a chamber 88 of the flange 8, in which the spring 6 is maintained substantially coplanar with the flange 8. This shape of spring 6 is placed between the flange 8 and the shaft 2. The spring 6 can not rotate on the shaft 2. The branches 61 and 62 of the spring are preloaded on the flange 8. A washer bearing on the shaft 2, and riveted on it carries an axial stop flange 8, and allows to trap and guide the spring 6 in the plane of the flange 8. During an impact, the branches 61 and 62 of the spring 6 are deformed, thus absorbing part of the impact energy. When the shock is over, the flange 8 returns to its initial position relative to the shaft 2.

Dans une rĆ©alisation alternative Ć  l'invention, aux figures 35 Ć  38, l'Ć©lĆ©ment flexible 9 est intĆ©grĆ© au flasque 8 et comporte deux lames-ressort 83, 84, dans son Ć©paisseur, sensiblement radiales et rentrantes, qui coopĆØrent en appui de frottement avec un secteur cylindrique excentrique creux 29 de l'arbre 2.In an alternative embodiment of the invention, Figures 35 to 38 , the flexible element 9 is integrated into the flange 8 and comprises two spring blades 83, 84, in its thickness, substantially radial and reentrant, which cooperate in frictional contact with a hollow eccentric cylindrical sector 29 of the shaft 2.

Dans un autre mode de rĆ©alisation non illustrĆ© voisin de l'invention, l'Ć©lĆ©ment flexible 9 est constituĆ© par un surmoulage d'Ć©lastomĆØre maintenant ensemble le flasque 8 et l'arbre 2. Ce surmoulage concerne un Ć©lastomĆØre avec une duretĆ© comprise entre 20 et 70 Shore A.In another non-illustrated embodiment of the invention, the flexible element 9 consists of an overmolding of elastomer holding together the flange 8 and the shaft 2. This overmoulding relates to an elastomer with a hardness of between 20 and 70 Shore A.
