Description

La présente invention concerne une virole d'horlogerie, plus particulièrement une virole permettant le chassage d'un spiral sur l'arbre d'un balancier dans un mouvement d'horlogerie.The present invention relates to a timepiece ferrule, more particularly a ferrule for driving a spiral on the shaft of a pendulum in a clockwork movement.

Les viroles que l'on trouve dans les mouvements d'horlogerie actuels sont souvent en acier ou en laiton et, généralement, se déforment plastiquement lors de leur chassage sur l'arbre du balancier. Toutefois, on connaît également des viroles élastiques aptes à serrer élastiquement l'arbre du balancier. Ces dernières présentent plusieurs avantages, dont celui de pouvoir être réalisées dans une matière cassante telle que le silicium. Une telle virole élastique est décrite dans le document EP 1 513 029. Elle comprend une structure élastique entourée par une structure de rigidification.The ferrules found in current watch movements are often made of steel or brass and, generally, deform plastically when they are driven on the balance shaft. However, resilient ferrules are also known capable of elastically tightening the balance shaft. The latter have several advantages, including that of being made in a brittle material such as silicon. Such an elastic shell is described in EP 1 513 029. It comprises an elastic structure surrounded by a stiffening structure.

La présente invention vise à fournir une virole élastique qui, par rapport aux viroles élastiques connues, en particulier celle selon EP 1 513 029, soit capable d'exercer une force de serrage plus importante et/ou de se déformer davantage.The present invention aims to provide an elastic ferrule which, with respect to the known elastic ferrules, in particular that according to EP 1 513 029, is capable of exerting a greater clamping force and / or of being more deformed.

A cette fin, il est prévu une virole selon la revendication 1 annexée, des modes de réalisation particuliers de cette virole étant définis dans les revendications dépendantes.To this end, there is provided a ferrule according to claim 1 attached, particular embodiments of this ferrule being defined in the dependent claims.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description détaillée suivante faite en référence à la figure annexée qui représente en vue de dessus une virole d'horlogerie selon un mode de réalisation préférentiel de l'invention.Other features and advantages of the present invention will appear on reading the following detailed description with reference to the appended figure which shows a top view of a clockwork ferrule according to a preferred embodiment of the invention.

En référence à la figure annexée, une virole 1 selon l'invention comprend une structure flexible intérieure 2 apte à recevoir et serrer élastiquement un arbre à section circulaire 3, typiquement un arbre de balancier, et une structure de rigidification extérieure 4 entourant la structure flexible 2. La structure de rigidification 4 est rattachée à la structure flexible 2 en des points distincts 5, définissant ainsi des évidements 6 entre les structures 2 et 4. La virole 1 est typiquement rattachée à l'extrémité intérieure d'un spiral (non représenté) en un point 7. La virole 1 et le spiral peuvent être réalisés en une seule pièce, par exemple en silicium.Referring to the attached figure, a ferrule 1 according to the invention comprises an inner flexible structure 2 adapted to receive and resiliently tighten a shaft with a circular section 3, typically a balance shaft, and an external stiffening structure 4 surrounding the flexible structure 2. The stiffening structure 4 is attached to the flexible structure 2 at distinct points 5, thus defining recesses 6 between the structures 2 and 4. The ferrule 1 is typically attached to the inner end of a hairspring (not shown) at a point 7. The shell 1 and the hairspring can be made in one piece, for example silicon.

La structure flexible 2 est de préférence sous la forme d'une courbe fermée régulière, telle qu'un polygone régulier, ayant un nombre déterminé de points de contact avec l'arbre de balancier 3, différents des points 5 de rattachement de la structure de rigidification 4 à la structure flexible 2. Dans l'exemple illustré, la structure flexible 2 est sensiblement en forme de triangle équilatéral et possède ainsi trois points de contact avec l'arbre 3, et ses sommets correspondent aux points de rattachement précités 5.The flexible structure 2 is preferably in the form of a regular closed curve, such as a regular polygon, having a determined number of points of contact with the balance shaft 3, different from the points of attachment of the structure of the structure. rigidification 4 to the flexible structure 2. In the example shown, the flexible structure 2 is substantially in the shape of an equilateral triangle and thus has three points of contact with the shaft 3, and its vertices correspond to the aforementioned points of attachment 5.

L'élasticité de la structure 2 résulte de l'épaisseur, relativement mince, dans le plan de la virole de chacun de ses côtés 8 destinés à être contact avec l'arbre 3. Cette épaisseur qui, comme on le verra plus loin, est variable, est calculée de manière que la contrainte maximale exercée par l'arbre de balancier 3 sur la structure 2 soit inférieure à la limite élastique du matériau formant la virole 1, que la virole 1 s'accommode des tolérances de fabrication de l'arbre de balancier 3 et que la tenue de la virole 1 sur l'arbre 3 (couple de rotation, force de chassage) soit adéquate. Grâce à sa forme fermée et régulière, la structure flexible 2 a un centre de gravité qui reste sensiblement le même avant et après le chassage de la virole sur l'arbre 3.The elasticity of the structure 2 results from the relatively thin thickness in the plane of the ferrule of each of its sides 8 intended to be in contact with the shaft 3. This thickness, which, as will be seen below, is variable, is calculated so that the maximum stress exerted by the balance shaft 3 on the structure 2 is less than the elastic limit of the material forming the shell 1, the shell 1 accommodates manufacturing tolerances of the shaft balance 3 and that the holding of the ferrule 1 on the shaft 3 (torque, driving force) is adequate. Due to its closed and regular shape, the flexible structure 2 has a center of gravity which remains substantially the same before and after the driving of the shell on the shaft 3.

De préférence, la structure de rigidification 4 est également sous la forme d'une courbe fermée et entoure ainsi complètement la structure flexible 2. Dans l'exemple illustré, la structure de rigidification 4 a une forme similaire à celle de la structure flexible 2, c'est-à-dire sensiblement triangulaire équilatérale, mais ses sommets 9, correspondant aux points de rattachement 5, c'est-à-dire aux sommets du triangle équilatéral formé par la structure flexible 2, sont arrondis. La structure de rigidification 4 a une épaisseur suffisante dans le plan de la virole pour quasiment ne pas se déformer lors du chassage de la virole sur l'arbre 3 et pour qu'en particulier les points de rattachement 5 et donc les sommets 9 restent sensiblement fixes par rapport au centre de la virole 1 lors de ce chassage. Ainsi, non seulement le centre de gravité de la virole 1 reste constant lors du chassage de la virole 1 sur l'arbre de balancier 3 mais également le point 7 de rattachement du spiral à la virole 1. Ceci améliore l'isochronisme du balancier-spiral.Preferably, the stiffening structure 4 is also in the form of a closed curve and thus completely surrounds the flexible structure 2. In the example illustrated, the stiffening structure 4 has a shape similar to that of the flexible structure 2, that is to say substantially equilateral triangular, but its vertices 9, corresponding to the points of attachment 5, that is to say to the vertices of the equilateral triangle formed by the flexible structure 2, are rounded. The stiffening structure 4 has a sufficient thickness in the plane of the ferrule to almost not deform during the driving of the shell on the shaft 3 and that in particular the points of attachment 5 and thus the vertices 9 remain substantially fixed relative to the center of the ferrule 1 during this hunting. Thus, not only the center of gravity of the ferrule 1 remains constant during the driving of the shell 1 on the balance shaft 3 but also the point 7 of attachment of the spiral to the ferrule 1. This improves the isochronism of the balance- spiral.

Conformément à l'invention, les côtés 8 de la structure flexible 2 ont une épaisseur variable dans le plan de la virole. Dans l'exemple illustré, cette épaisseur présente des maxima ep0, ep1 et ep2 respectivement au centre et aux deux extrémités de chaque côté 8 et des minima ep3 et ep4 à mi-distance entre le centre et les deux extrémités de chaque côté 8, respectivement. De préférence, les maxima ep0, ep1 et ep2 sont égaux entre eux et les minima ep3 et ep4 sont égaux entre eux, comme illustré sur la figure.According to the invention, the sides 8 of the flexible structure 2 have a variable thickness in the plane of the ferrule. In the illustrated example, this thickness has maxima ep0, ep1 and ep2 respectively at the center and at the two ends of each side 8 and the minima ep3 and ep4 at mid-distance between the center and the two ends of each side 8, respectively . Preferably, the maxima ep0, ep1 and ep2 are equal to each other and the minima ep3 and ep4 are equal to each other, as illustrated in the figure.

Cette variation d'épaisseur des côtés 8 de la structure flexible 2 permet de mieux répartir la contrainte exercée par l'arbre de balancier 3 le long de chacun desdits côtés. Ainsi, là où les côtés 8 sont soumis à une force de grande intensité, à savoir dans leur partie centrale en contact avec l'arbre de balancier et à leurs deux extrémités, l'épaisseur (ep0, ep1 et ep2) est grande, ce qui localement augmente la résistance des côtés 8 et diminue la contrainte subie par ces derniers, et là où les côtés 8 sont soumis à une contrainte de petite intensité, voire d'intensité nulle, à savoir à mi-distance entre leur centre et leurs deux extrémités respectivement, l'épaisseur (ep3 et ep4) est petite, ce qui favorise la déformation (ou flèche) des côtés 8 par l'arbre de balancier 3. De cette manière, il est possible de faire subir aux côtés 8 par exemple une force plus grande que dans le cas de la virole selon EP 1 513 029 pour une même déformation (ou flèche) desdits côtés (avec une épaisseur ep0 ep1, ep2 supérieure à l'épaisseur des côtés de la structure flexible de la virole selon EP 1 513 029), pour augmenter la force de serrage de l'arbre de balancier, ou une déformation plus grande que dans le cas de la virole selon EP 1 513 029 pour une même force exercée par l'arbre de balancier (avec une épaisseur ep0, ep1, ep2 égale à l'épaisseur des côtés de la structure flexible de la virole selon EP 1 513 029), pour rendre la virole moins sensible aux tolérances de fabrication. Des cas intermédiaires sont bien entendu également possibles dans lesquels à la fois la force de serrage et la déformation sont augmentées par rapport à la virole selon EP 1 513 029.This variation in thickness of the sides 8 of the flexible structure 2 makes it possible to better distribute the stress exerted by the balance shaft 3 along each of said sides. Thus, where the sides 8 are subjected to a force of great intensity, namely in their central part in contact with the balance shaft and at their two ends, the thickness (ep0, ep1 and ep2) is large; which locally increases the resistance of the sides 8 and reduces the stress experienced by the latter, and where the sides 8 are subjected to a stress of small intensity or zero intensity, namely mid-distance between their center and their two ends respectively, the thickness (ep3 and ep4) is small, which promotes the deformation (or arrow) of the sides 8 by the balance shaft 3. In this way, it is possible to subject the sides 8 for example a greater force than in the case of the ferrule according to EP 1 513 029 for the same deformation (or arrow) of said sides (with a thickness ep0 ep1, ep2 greater than the thickness of the sides of the flexible structure of the shell according to EP 1 513,029), to increase the force e of clamping of the balance shaft, or a greater deformation than in the case of the shell according to EP 1 513 029 for the same force exerted by the balance shaft (with a thickness ep0, ep1, ep2 equal to 1 thickness of the sides of the flexible structure of the ferrule according to EP 1 513 029), to make the ferrule less sensitive to manufacturing tolerances. Intermediate cases are of course also possible in which both the clamping force and the deformation are increased relative to the ferrule according to EP 1 513 029.
