Abstract

The collet has an inner flexible structure (10) that elastically clasps a balance shaft (4). An outer rigid structure (11) is connected to the flexible structure at different attachment points (12a-12c). A spiral spring (2) is attached with the rigid structure at an attachment point (3) that is fixed on the shaft while pressing a collet-spiral assembly. The collet is made up of silicon. An independent claim is also included for a balance-spiral assembly comprising a horological balance and a spiral-collet assembly.

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 watch 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 connaít 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. Elles sont par exemple sous la forme d'une bague fendue radialement, comme décrit dans les documents CH 490.703 et FR 1.376.018, ou d'une structure mince fermée assurant un contact en différents points avec l'arbre de balancier, comme décrit dans l'article intitulé « Caractéristiques chronométriques du système Viroflex », de Christian Faivre et Germain Maillard, publié par la Société Suisse de Chronométrie, 56ème congrès, Neuchâtel, 23 et 24 octobre 1981.The ferrules found in the current watch movements are often made of steel or brass and usually deform plastically when they are driven on the balance shaft. However, there are also known resilient ferrules adapted to elastically tighten the balance shaft. The latter have several advantages, including that of being made in a brittle material such as silicon. They are for example in the form of a radially split ring, as described in documents CH 490.703 and FR 1.376.018, or of a closed thin structure providing contact at different points with the balance shaft, as described in FIG. the article entitled "characteristics Viroflex system chronometric" Christian Faivre and Germain Maillard, published by the Swiss Society Chronometry, 56 th Congress, Neuchâtel, 23 and 24 October 1981.

Un inconvénient des viroles élastiques réside dans le fait qu'elles diminuent l'isochronisme du balancier-spiral. Dans le cas des viroles en forme de bague fendue radialement, la virole, en s'ouvrant pour recevoir l'arbre de balancier, voit en effet son centre de gravité se déplacer, ce qui génère un balourd dans le système balancier-spiral. Dans le cas de la virole en forme de courbe fermée telle qu'exposée dans l'article susmentionné, la forme régulière de la virole fait que le centre de gravité de cette dernière ne se déplace quasiment pas lors du chassage. En revanche, le point d'attache du spiral sur la virole, situé sur le pourtour de la virole, lui, se déplace, ce qui décentre le spiral.A disadvantage of elastic ferrules lies in the fact that they decrease the isochronism of the sprung balance. In the case of ferrules ring-shaped radially split, the shell, opening to receive the balance shaft, sees indeed its center of gravity move, which generates an unbalance in the balance spring system. In the case of the ferrule in the form of a closed curve such as explained in the above-mentioned article, the regular shape of the ferrule center of gravity of the latter hardly moves during the chassage. On the other hand, the point of attachment of the hairspring on the shell, located on the around the shell, it moves, which decenter the spiral.

La présente invention vise à fournir une virole élastique qui, par rapport aux viroles élastiques conventionnelles, permette de réduire le déplacement du point d'attache du spiral sur la virole lors du chassage de cette dernière sur l'arbre de balancier et d'améliorer ainsi l'isochronisme du balancier-spiral.The present invention aims to provide an elastic ferrule which, with respect to conventional elastic shells, reduces the displacement of the point attachment of the hairspring on the shell when driving the latter on the shaft of pendulum and thus improve the isochronism of the sprung balance.

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, ainsi qu'un ensemble virole-spiral et un ensemble balancier-spiral l'incorporant.For this purpose, there is provided a ferrule according to the appended claim 1, particular embodiments of this ferrule being defined in the dependent claims, together with a ferrule-spiral assembly and a set balance-spiral incorporating it.

D'autres caractéristiques et avantages de la présente invention apparaítront à la lecture de la description détaillée suivante faite en référence à la figure annexée qui montre un ensemble virole-spiral selon un mode de réalisation préférentiel de l'invention.Other features and advantages of the present invention will become apparent upon reading the following detailed description made with reference to FIG. attached which shows a ferrule-spiral assembly according to an embodiment preferential of the invention.

L'ensemble virole-spiral illustré sur la figure est réalisé en une seule pièce, typiquement en silicium. Il comporte une virole 1 et un ressort spiral 2 rattaché au niveau de son extrémité intérieure 20 à un point 3 sur le pourtour de la virole 1. L'ensemble virole-spiral est maintenu sur un arbre de balancier 4 à section circulaire par chassage de la virole 1 sur cet arbre 4. De manière connue en soi, l'extrémité extérieure 21 du spiral 2 est fixée à un piton 5.The ferrule-spiral assembly illustrated in the figure is made in one piece, typically silicon. It comprises a ferrule 1 and a spiral spring 2 attached to the level of its inner end 20 to a point 3 on the periphery of the ferrule 1. The ferrule-spiral assembly is held on a balance shaft 4 with section circular by driving the shell 1 on this shaft 4. In a manner known per se, the outer end 21 of the hairspring 2 is fixed to a peg 5.

La virole 1 comporte une structure flexible intérieure 10 recevant et serrant élastiquement l'arbre de balancier 4 et une structure de rigidification extérieure 11 entourant la structure flexible 10. La structure de rigidification 11 est rattachée à cette dernière en des points distincts 12a, 12b et 12c, définissant ainsi des évidements 13a, 13b et 13c entre les structures 10 et 11.The ferrule 1 has a flexible inner structure 10 receiving and squeezing resiliently the balance shaft 4 and an external stiffening structure 11 surrounding the flexible structure 10. The stiffening structure 11 is attached to the latter at distinct points 12a, 12b and 12c, thus defining recesses 13a, 13b and 13c between the structures 10 and 11.

La structure flexible 10 est de préférence sous la forme d'une courbe fermée régulière, typiquement un polygone régulier, ayant un nombre déterminé de points de contact avec l'arbre de balancier 4, différents des points 12a, 12b, 12c de rattachement de la structure de rigidification 11 à la structure flexible 10. Dans l'exemple illustré, la structure flexible 10 est sensiblement en forme de triangle équilatéral et possède ainsi trois points de contact 14a, 14b et 14c avec l'arbre 4, et ses sommets correspondent aux points de rattachement précités 12a, 12b, 12c. L'élasticité de la structure 10 résulte de l'épaisseur, relativement mince, de cette dernière. Cette épaisseur est calculée de manière que la contrainte maximale exercée par l'arbre de balancier 4 sur la structure 10 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 4 et que la tenue de la virole 1 sur l'arbre 4 (couple de rotation, force de chassage) soit adéquate. Grâce à sa forme fermée et régulière, la structure flexible 10 a un centre de gravité G qui reste sensiblement le même avant et après le chassage sur l'arbre 4.The flexible structure 10 is preferably in the form of a curve regular closed, typically a regular polygon, having a determined number points of contact with the balance shaft 4, different from the points 12a, 12b, 12c of attachment of the stiffening structure 11 to the flexible structure 10. In the example shown, the flexible structure 10 is substantially shaped equilateral triangle and thus has three points of contact 14a, 14b and 14c with the shaft 4, and its vertices correspond to the aforementioned points of attachment 12a, 12b, 12c. The elasticity of the structure 10 results from the relatively thin, of the latter. This thickness is calculated in such a way that the constraint maximum force exerted by the balance shaft 4 on the structure 10 is less than the elastic limit of the material forming the ferrule 1, that the ferrule 1 accommodates manufacturing tolerances of the balance shaft 4 and that the holding of the shell 1 on the shaft 4 (torque, driving force) is adequate. Thanks to its shape closed and regular, the flexible structure 10 has a center of gravity G that remains substantially the same before and after the chase on the tree 4.

De préférence, la structure de rigidification 11 est également sous la forme d'une courbe fermée et entoure ainsi complètement la structure flexible 10. Dans l'exemple illustré, la structure de rigidification 11 a une forme similaire à celle de la structure flexible 10, c'est-à-dire sensiblement triangulaire équilatérale, mais ses sommets 15a, 15b, 15c, correspondant aux points de rattachement 12a, 12b, 12c, c'est-à-dire aux sommets du triangle équilatéral formé par la structure flexible 10, sont arrondis. Afin de rendre plus solide l'ensemble virole-spiral au voisinage du point 3 de rattachement de l'extrémité intérieure 20 du spiral 2 à la virole 1, plus précisément à la structure 11, ladite extrémité intérieure 20 constitue de préférence sensiblement un prolongement de l'un des sommets arrondis de la structure 11, à savoir le sommet 15a correspondant au point de rattachement 12a. On notera à cet égard que pour assurer une quasi-continuité de forme entre le sommet 15a de la structure de rigidification 11 et l'extrémité intérieure 20 du spiral 2, le sommet 15a, à la différence des sommets 15b, 15c, a un centre de courbure qui est distinct du centre de gravité G de la structure flexible 10. Pour rééquilibrer la virole 1, c'est-à-dire faire en sorte que son centre de gravité corresponde au centre de gravité G de la structure flexible 10 et soit ainsi sur l'axe de l'arbre de balancier 4, on prévoit sur cette virole 1 une zone de compensation, constituée par exemple par une surépaisseur variable e formée sur l'un des côtés du triangle défini par la structure de rigidification 11, en l'occurrence le côté situé entre les sommets 15b et 15c, comme illustré sur la figure. La forme et les dimensions de cette zone de compensation peuvent être déterminées de façon appropriée par une méthode de rééquilibrage connue en soi.Preferably, the stiffening structure 11 is also in the form of a closed curve and thus completely surrounds the flexible structure 10. In the illustrated example, the stiffening structure 11 has a shape similar to that of the flexible structure 10, that is to say substantially triangular equilateral, but its vertices 15a, 15b, 15c, corresponding to the points of attachment 12a, 12b, 12c, that is to say at the vertices of the equilateral triangle formed by the flexible structure 10, are rounded. In order to make the ferrule-spiral assembly more solid in the vicinity of point 3 of attachment of the inner end 20 of the spiral 2 to the ferrule 1, plus precisely to the structure 11, said inner end 20 constitutes preferably substantially an extension of one of the rounded corners of the structure 11, namely the vertex 15a corresponding to the point of attachment 12a. It should be noted in this regard that to ensure a quasi-continuity of form between the top 15a of the stiffening structure 11 and the inner end 20 of the hairspring 2, the vertex 15a, unlike the vertices 15b, 15c, has a center of curvature which is distinct from the center of gravity G of the flexible structure 10. To rebalance the shell 1, that is to say, to ensure that its center of gravity corresponds to the center of gravity G of the flexible structure 10 and thus be on the axis of the shaft of pendulum 4, there is provided on this shell 1 a compensation zone, constituted by example by a variable allowance e formed on one of the sides of the triangle defined by the stiffening structure 11, in this case the side between the vertices 15b and 15c, as shown in the figure. The shape and dimensions of this compensation area can be appropriately determined by a rebalancing method known per se.

La structure de rigidification 11 a une épaisseur suffisante pour quasiment ne pas se déformer lors du chassage et pour qu'en particulier les points de rattachement 12a, 12b, 12c et donc les sommets 15a, 15b, 15c restent sensiblement fixes par rapport au centre de la virole 1 lors de ce chassage. Ainsi, dans l'invention, non seulement le centre de gravité de la virole 1 reste constant lors du chassage de l'ensemble virole-spiral sur l'arbre de balancier 4 mais également le point 3 de rattachement du spiral 2 à la virole 1. Il en découle une amélioration de l'isochronisme du balancier-spiral.The stiffening structure 11 has a thickness sufficient for almost not to deform during the chase and that in particular the points of attachment 12a, 12b, 12c and therefore the vertices 15a, 15b, 15c remain substantially fixed relative to the center of the ferrule 1 during this hunting. So, in the invention, not only the center of gravity of the ferrule 1 remains constant when driving the ferrule-spiral assembly on the balance shaft 4 but also the point 3 of attachment of the spiral 2 to the ferrule 1. It follows a improvement of the isochronism of the sprung balance.
