Description

La présente invention concerne un composant horloger, c'est-à-dire un composant destiné à être intégré dans une pièce d'horlogerie telle qu'une montre ou une pendule. La présente invention concerne plus particulièrement un composant horloger, par exemple une roue ou une virole, destiné à être monté élastiquement sur un axe.The present invention relates to a timepiece component, that is to say a component intended to be integrated into a timepiece such as a watch or a pendulum. The present invention more particularly relates to a timepiece component, for example a wheel or a ferrule, intended to be resiliently mounted on an axis.

Un tel composant comprend des bras élastiques agencés pour serrer l'axe et ainsi maintenir le composant sur celui-ci. Les bras peuvent être droits. Ils peuvent aussi avoir une forme non droite, par exemple en V, pour augmenter leur longueur de sorte à permettre, en ajustant leurs autres dimensions, d'augmenter leur raideur et donc la force de serrage de l'axe. Des exemples de tels composants à bras élastiques droits ou non droits sont décrits dans les documents EP 1 513 029 , EP 1 705 533 , EP 1 708 045 et JP 59 135385 .Such a component comprises elastic arms arranged to clamp the axis and thus maintain the component thereon. The arms can be straight. They may also have a non-straight form, for example V, to increase their length so as to allow, by adjusting their other dimensions, to increase their stiffness and thus the clamping force of the axis. Examples of such components with straight or non-straight elastic arms are described in the documents EP 1,513,029 , EP 1 705 533 , EP 1 708 045 and JP 59 135385 .

Lors du montage du composant sur l'axe, ce dernier déforme les bras pour qu'ils exercent leur fonction de serrage élastique. Cette déformation des bras entraîne une déformation ou mal-rond du pourtour du composant. Dans certains cas, en particulier lorsque les bras sont rattachés par leurs deux extrémités au reste du composant et ont une forme non droite, le mal-rond du pourtour peut être important. Un tel mal-rond peut être préjudiciable au fonctionnement du composant, notamment lorsque le pourtour a une fonction active telle qu'une fonction d'engrènement.When mounting the component on the axis, the latter deforms the arms so that they exert their elastic clamping function. This deformation of the arms causes a deformation or poorly round the periphery of the component. In some cases, particularly when the arms are attached at both ends to the rest of the component and have a non-straight shape, the roundness of the periphery may be important. Such a roundness can be detrimental to the operation of the component, especially when the periphery has an active function such as a meshing function.

La présente invention vise à proposer un composant horloger apte à être monté élastiquement sur un axe et dont la déformation du pourtour due à son montage sur l'axe reste limitée.The present invention aims to provide a watch component adapted to be mounted elastically on an axis and whose deformation of the periphery due to its mounting on the axis remains limited.

A cette fin est prévu un composant horloger destiné à être monté sur un axe et comprenant une partie centrale et une partie périphérique, la partie centrale comprenant des bras de serrage élastique de l'axe et une partie extérieure entourant les bras et à laquelle les bras sont rattachés, caractérisé en ce qu'il comprend des lumières entre la partie périphérique et la partie extérieure, ces lumières étant agencées de telle sorte que la partie périphérique est rattachée à la partie extérieure en des zones discrètes de cette dernière comprenant chacune un point qui n'est pas déplacé lors de la déformation des bras par l'axe.For this purpose there is provided a clock component intended to be mounted on an axis and comprising a central portion and a peripheral portion, the central portion comprising elastic clamping arms of the axis and an outer portion surrounding the arms and to which the arms are attached, characterized in that comprises lights between the peripheral portion and the outer portion, these lights being arranged such that the peripheral portion is attached to the outer portion in discrete areas thereof each comprising a point that is not displaced during the deformation arms by the axis.

Des modes de réalisation particuliers de l'invention sont définis dans les revendications dépendantes annexées.Particular embodiments of the invention are defined in the appended dependent claims.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description détaillée suivante faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue de dessus d'une roue d'échappement selon un premier mode de réalisation de l'invention, destinée à être montée sur un axe représenté en trait pointillé ;
  • la figure 2 est un tiers de vue de dessus de la roue d'échappement illustrée à la figure 1, montrant cette roue dans un état non déformé (trait continu) avant son montage sur l'axe et dans un état déformé (trait pointillé) après son montage sur l'axe ; et
  • la figure 3 est une vue de dessus d'une roue d'échappement selon un deuxième mode de réalisation de l'invention.
Other features and advantages of the present invention will appear on reading the following detailed description given with reference to the accompanying drawings in which:
  • the figure 1 is a top view of an escape wheel according to a first embodiment of the invention, intended to be mounted on an axis shown in broken lines;
  • the figure 2 is a third of top view of the escape wheel shown in the figure 1 , showing this wheel in an undistorted state (solid line) before it is mounted on the axis and in a deformed state (dashed line) after it has been mounted on the axis; and
  • the figure 3 is a top view of an escape wheel according to a second embodiment of the invention.

En référence à la figure 1, un composant horloger selon un premier mode de réalisation de l'invention consiste en une roue d'échappement comprenant une partie centrale ou intérieure 1 et une partie périphérique ou extérieure 2.With reference to the figure 1 , a watch component according to a first embodiment of the invention consists of an escape wheel comprising a central or inner part 1 and a peripheral or outer part 2.

La partie centrale 1 comporte trois bras élastiques 3 en V placés à 120° les uns par rapport aux autres autour de l'axe imaginaire 4 de la roue et une partie extérieure ou périphérique circulaire 5, d'axe 4, qui entoure les bras 3 et à laquelle chaque bras 3 est rattaché par ses deux extrémités. Les bras 3 et la partie extérieure 5 sont définis par des premières lumières 6 formées dans la partie centrale 1. Les pointes respectives des V définissent des surfaces concaves 7 agencées à 120° les unes par rapport aux autres à proximité et autour de l'axe imaginaire 4. Ces surfaces 7 sont les surfaces de contact de la roue avec l'axe (physique) 8 sur lequel elle est destinée à être montée. L'axe 8 a un diamètre supérieur au diamètre de la zone entre les surfaces 7 de sorte que son introduction dans cette zone déforme les bras 3 vers la partie périphérique 2, causant un serrage de l'axe 8 par les bras 3 et ainsi le maintien de la roue sur l'axe 8. Dans cette position assemblée de la roue et de l'axe 8, l'axe imaginaire de ce dernier coïncide avec l'axe imaginaire 4 de la roue. Les bras 3 ont une largeur variable pour que les contraintes que leur fait subir l'axe 8 soient réparties de façon plus homogène sur toute leur longueur.The central portion 1 comprises three V-shaped elastic arms 3 placed at 120 ° relative to one another about the imaginary axis 4 of the wheel and an outer or circular peripheral portion 5, of axis 4, which surrounds the arms 3 and to which each arm 3 is attached by its two ends. The arms 3 and the outer portion 5 are defined by first lumens 6 formed in the central portion 1. The respective tips of the V define concave surfaces 7 arranged at 120 ° relative to each other in the vicinity and around the axis imaginary 4. These surfaces 7 are the contact surfaces of the wheel with the axis (physical) 8 on which it is intended to be mounted. The axis 8 has a diameter greater than the diameter of the zone between the surfaces 7 so that its introduction into this zone deforms the arms 3 towards the peripheral part 2, causing the axis 8 to be clamped by the arms 3 and thus the maintaining the wheel on the axis 8. In this assembled position of the wheel and the axis 8, the imaginary axis of the latter coincides with the imaginary axis 4 of the wheel. The arms 3 have a variable width so that the stresses that makes them undergo the axis 8 are distributed more evenly over their entire length.

La partie périphérique 2, dite également serge de la roue, comporte la denture 9 de la roue. La partie périphérique 2 entoure coaxialement la partie centrale 1 et est rattachée à cette dernière uniquement en des zones discrètes 10 de la partie extérieure 5. A cet effet, la roue comporte des deuxièmes lumières 11, au nombre de six dans l'exemple illustré, qui séparent la partie périphérique 2 de la partie extérieure 5 sauf au niveau des intervalles 12 entre les lumières 11. Ces lumières 11 sont disposées suivant un cercle coaxial avec la partie périphérique 2 et la partie extérieure 5 et forment ainsi une ligne circulaire interrompue. Les intervalles 12 entre les lumières 11 constituent des parties discrètes de liaison de la partie périphérique 2 aux zones discrètes 10 de la partie extérieure 5 et sont alignés radialement avec les zones discrètes 10. La position et la longueur des lumières 11 sont déterminées de telle sorte que les zones discrètes 10 soient des zones de moindre déplacement, c'est-à-dire des zones contenant chacune un point qui n'est pas déplacé lors de l'introduction de l'axe 8 entre les bras 3. Ces zones de moindre déplacement peuvent être déterminées par des méthodes de simulation connues de l'homme du métier, par exemple par une méthode à éléments finis. Le nombre de ces zones, six dans l'exemple illustré, dépend du nombre et de la géométrie des bras 3.The peripheral portion 2, also called serge of the wheel, has the toothing 9 of the wheel. The peripheral portion 2 coaxially surrounds the central portion 1 and is attached thereto only in discrete zones 10 of the outer portion 5. For this purpose, the wheel comprises second lights 11, six in number in the illustrated example, which separate the peripheral portion 2 of the outer portion 5 except at the intervals 12 between the slots 11. These slots 11 are arranged in a circle coaxial with the peripheral portion 2 and the outer portion 5 and thus form a broken circular line. The gaps 12 between the slots 11 constitute discrete portions of connection of the peripheral portion 2 to the discrete zones 10 of the outer part 5 and are aligned radially with the discrete zones 10. The position and the length of the slots 11 are determined in such a way that the discrete zones 10 are areas of least displacement, that is to say zones each containing a point that is not displaced during the introduction of the axis 8 between the arms 3. These areas of less displacement can be determined by simulation methods known to those skilled in the art, for example by a finite element method. The number of these zones, six in the illustrated example, depends on the number and the geometry of the arms 3.

La figure 2 montre de manière exagérée la déformation de la roue lors de son montage sur l'axe 8. On voit qu'au droit de certaines lumières 11a la partie extérieure 5 se déforme vers l'extérieur tandis qu'au droit d'autres lumières 11 b la partie extérieure 5 se déforme vers l'intérieur. Entre deux lumières consécutives 11 a, 11 b, dans chaque zone discrète 10, le sens des déformations locales de la partie extérieure 5 change, ce qui implique qu'il existe dans cette zone un (unique) point de déplacement nul. Comme la partie périphérique 2 est rattachée à la partie centrale 1 uniquement en des zones de moindre déplacement, elle n'est que peu affectée par la déformation de la partie centrale 1 due à l'axe 8. Sa déformation et donc le mal-rond de la roue sont dès lors réduits, permettant ainsi une coopération fiable entre cette roue et une ancre d'échappement. Dans l'exemple illustré aux figures 1 et 2, pour une force de tenue de la roue sur l'axe 8 de 2 Newtons, un mal-rond de 1,8 µm a été constaté après montage de la roue sur l'axe 8. Pour la même force de tenue, le mal-rond est de 7 µm si la roue ne comporte pas les lumières 11.The figure 2 shows exaggeratedly the deformation of the wheel during its mounting on the axis 8. It can be seen that at the right of certain lights 11a the outer part 5 deforms outwards while at the right of other lights 11b the outer portion 5 deforms inwardly. Between two consecutive lights 11a, 11b, in each discrete zone 10, the direction of the local deformations of the outer part 5 changes, which implies that there exists in this zone a (single) point of zero displacement. As the peripheral portion 2 is attached to the central portion 1 only in areas of less displacement, it is only slightly affected by the deformation of the central portion 1 due to the axis 8. Its deformation and therefore the poorly-rounded of the wheel are reduced, thus allowing a reliable cooperation between this wheel and an exhaust anchor. In the example shown in figures 1 and 2 for a force holding the wheel on the axis 8 of 2 Newtons, a roundness of 1.8 microns was found after mounting the wheel on the axis 8. For the same holding force, the evil -rond is 7 μm if the wheel does not include the lights 11.

La présente invention n'est pas limitée à un nombre de bras particulier. La figure 3 montre une roue d'échappement selon un deuxième mode de réalisation de l'invention, comportant deux bras élastiques 13 en V placés à 180° l'un par rapport à l'autre autour de l'axe imaginaire de la roue. Dans cet exemple de la figure 3, un mal-rond de la roue de 2,8 µm pour une force de tenue de 1,5 Newtons a été constaté, à comparer avec un mal-rond de 10 µm constaté dans le cas où les lumières 11 sont omises.The present invention is not limited to a particular number of arms. The figure 3 shows an escape wheel according to a second embodiment of the invention, comprising two elastic arms 13 V placed at 180 ° relative to each other about the imaginary axis of the wheel. In this example of the figure 3 a poor roundness of the wheel of 2.8 microns for a holding force of 1.5 Newtons was found, compared with a poor roundness of 10 microns found in the case where the lights 11 are omitted.

Dans la présente invention, le nombre de zones discrètes de rattachement 10 peut être égal ou inférieur au nombre de zones de moindre déplacement de la partie extérieure 5. Dans les exemples des figures 1 et 3, il est égal au nombre de zones de moindre déplacement. Un nombre inférieur de zones discrètes 10 peut être obtenu, à partir de l'un ou l'autre des exemples des figures 1 et 3, en prolongeant deux lumières 11 consécutives pour qu'elles se rejoignent.In the present invention, the number of discrete zones of attachment 10 may be equal to or less than the number of zones of least displacement of the outer portion 5. In the examples of figures 1 and 3 , it is equal to the number of zones of least displacement. A smaller number of discrete areas can be obtained from one or other of the examples of figures 1 and 3 by extending two consecutive lights 11 to meet each other.

Bien que le problème de mal-rond soit plus particulièrement critique dans le cas de bras élastiques de forme non droite, tels que les bras en V 3 et 13 des figures 1 et 3, la présente invention n'exclut pas de donner une forme droite aux bras. La présente invention n'exclut pas non plus que les bras soient rattachés à la partie extérieure 5 par l'une de leurs extrémités seulement.Although the problem of roundness is more particularly critical in the case of non-straight elastic arms, such as V-arms 3 and 13 of figures 1 and 3 the present invention does not exclude giving a straight form to arms. The present invention does not exclude that the arms are attached to the outer portion 5 by one of their ends only.

La présente invention peut s'appliquer à d'autres composants horlogers qu'une roue d'échappement. A titre d'exemples complémentaires, le composant horloger selon l'invention peut être une roue dentée d'engrènement, un râteau, une virole de spiral, une ancre d'échappement, un balancier ou un petit plateau destiné à être monté sur l'axe d'un balancier-spiral pour coopérer avec le dard d'une ancre d'échappement. Dans les cas de la roue d'engrènement, du râteau, de l'ancre et du petit plateau, la faible déformation de leur pourtour lors de leur montage sur leur axe, permise par la présente invention, augmente la fiabilité de leur fonctionnement, c'est-à-dire de leur coopération avec leurs partenaires respectifs (roue d'engrènement, roue d'échappement et dard). Dans le cas de la virole, la faible déformation de son pourtour lors de son montage sur l'axe permet de maintenir sensiblement fixe le point d'attache du spiral à la virole et d'améliorer ainsi l'isochronisme du balancier-spiral. Enfin, dans le cas du balancier, l'invention permet de maintenir son inertie sensiblement constante lors de son montage sur l'axe.The present invention can be applied to other watch components than an escape wheel. As additional examples, the watch component according to the invention may be a meshing gear, a rake, a spiral shell, an escape anchor, a rocker or a small plate to be mounted on the axis of a sprung balance to cooperate with the stinger of an exhaust anchor. In the case of the meshing wheel, the rake, the anchor and the small plate, the small deformation of their periphery when mounted on their axis, permitted by the present invention, increases the reliability of their operation, c that is to say, of their cooperation with their respective partners (meshing wheel, escape wheel and dart). In the case of the ferrule, the small deformation of its periphery during its assembly on the axis makes it possible to maintain substantially fixed the point of attachment of the spiral to the ferrule and thus improve the isochronism of the sprung balance. Finally, in the case of the balance, the invention maintains its inertia substantially constant when mounted on the axis.

Le composant horloger selon l'invention, en particulier sa partie périphérique, n'a pas nécessairement une forme circulaire. Il pourrait avoir une autre forme, par exemple polygonale, selon la fonction du composant.The watch component according to the invention, in particular its peripheral part, does not necessarily have a circular shape. It could have another shape, for example polygonal, depending on the function of the component.
