Arrière-plan de l'inventionInvention background

La confection de petits composants d'horlogerie, en particulier de mobiles, est toujours une préoccupation pour l'industriel, en raison de coûts d'usinage qui peuvent être élevés, et de la difficulté pour réaliser certaines géométries, en particulier quand le composant concerné a de gros écarts de section, comme c'est le cas, par exemple, pour un balancier : un tel mobile doit avoir un pivotement parfait malgré un petit diamètre de pivot, et doit être suffisamment résistant aux chocs, tout voile se traduisant par un balourd préjudiciable au maintien d'une fréquence d'oscillation constante.The manufacture of small timepiece components, in particular of mobiles, is always a concern for the industrialist, because of machining costs which can be high, and the difficulty to produce certain geometries, in particular when the component concerned has large cross-sectional deviations, as is the case, for example, for a pendulum: such a mobile must have perfect pivoting despite a small pivot diameter, and must be sufficiently resistant to impact, any veil resulting in a imbalance detrimental to the maintenance of a constant oscillation frequency.

Description détaillée des modes de réalisation préférésDetailed description of preferred embodiments

L'invention concerne un composant 1 d'horlogerie, plus particulièrement un mobile d'horlogerie. Ce composant 1 comporte une partie arbrée 2, laquelle comporte au moins un pivot 3 autour d'un axe de pivot D.The invention relates to a timepiece component 1, more particularly a timepiece mobile. This component 1 comprises a shafted part 2, which comprises at least one pivot 3 around a pivot axis D.

Selon l'invention, au moins le matériau constitutif de la partie arbrée 2 est une céramique, ou similaire.According to the invention, at least the constituent material of the shafted part 2 is a ceramic, or the like.

Et cette partie arbrée 2 comporte une pluralité d'évidements 7, qui sont équilibrés autour de l'axe de pivot D, et notamment qui sont répartis régulièrement autour de l'axe de pivot D, et a son centre d'inertie sur l'axe de pivot D.And this shafted part 2 comprises a plurality of recesses 7, which are balanced around the pivot axis D, and in particular which are distributed regularly around the pivot axis D, and has its center of inertia on the pivot axis D.

Cette partie arbrée 2 comporte une zone de plus grand diamètre, appelée collerette 9, qui constitue son plus grand diamètre par rapport à l'axe de pivot D.This shafted part 2 has an area of larger diameter, called a flange 9, which constitutes its largest diameter relative to the pivot axis D.

Plus particulièrement cette collerette 9 comporte un plan de joint 90 de la partie arbrée 2, lequel plan de joint 90 est sensiblement perpendiculaire à l'axe de pivot D.More particularly, this flange 9 comprises a joint plane 90 of the shafted part 2, which joint plane 90 is substantially perpendicular to the pivot axis D.

Plus particulièrement, la collerette 9 est traversée par les évidements 7.More particularly, the flange 9 is crossed by the recesses 7.

Dans une réalisation particulière et avantageuse quand le matériau constitutif de la partie arbrée 2 est injectable, au moins un évidement 7 renferme un point d'injection 8 du matériau. Plus particulièrement, chaque évidement 7 renferme un point d'injection 8 du matériau. De façon avantageuse, le point d'injection 8 est situé dans la zone de l'évidement 7 qui est la plus proche de l'axe de pivot D. Et, dans une variante particulière, le point d'injection est situé, selon la direction de l'axe D, au niveau du milieu de la collerette 9.In a particular and advantageous embodiment when the material constituting the tree part 2 is injectable, at least one recess 7 contains an injection point 8 of the material. More particularly, each recess 7 contains an injection point 8 of the material. Advantageously, the injection point 8 is located in the zone of the recess 7 which is closest to the pivot axis D. And, in a particular variant, the injection point is located, according to the direction of axis D, at the middle of the collar 9.

Le logement du point d'injection 8 dans un évidement 7 est particulièrement avantageux, car de ce fait il n'existe aucune interférence avec quelque portée fonctionnelle de révolution que ce soit. De plus, dans le cas particulier illustré par les figures d'évidements 7 cylindriques, une retouche éventuelle du point d'injection 8 est extrêmement facile, et ne risque absolument pas de blesser une portée fonctionnelle.Housing the injection point 8 in a recess 7 is particularly advantageous, because therefore there is no interference with any functional range of revolution whatsoever. In addition, in the particular case illustrated by the cylindrical recess figures 7, any retouching of the injection point 8 is extremely easy, and absolutely does not risk injuring a functional range.

Dans un autre mode de réalisation, au moins un point d'injection se situe dans une autre partie non fonctionnelle de la partie arbrée 2, par exemple sous le plus grand diamètre, ou se situe dans une autre partie non fonctionnelle du composant 1 réalisée avec la partie arbrée 2 et dans le même matériau, notamment une céramique. Par partie non fonctionnelle on entend ici une partie du composant dont aucune surface n'est agencée pour coopérer avec un autre composant d'un mécanisme d'horlogerie.In another embodiment, at least one injection point is located in another non-functional part of the shafted part 2, for example under the largest diameter, or is located in another non-functional part of the component 1 produced with the tree part 2 and in the same material, in particular a ceramic. By non-functional part is meant here a part of the component of which no surface is arranged to cooperate with another component of a timepiece mechanism.

Dans une variante, le point d'injection 8 est logé dans le fond d'une gorge de révolution.In a variant, the injection point 8 is housed in the bottom of a groove of revolution.

Pour une fabrication par injection dans un moule en deux parties de part et d'autre du plan de joint 90, la section de la partie arbrée décroit depuis le plan de joint 9 vers chaque extrémité distale comportant de préférence un pivot 3 et/ou un tigeron. Cette exécution permet d'obtenir les portées de pivot sans couture d'injection.For a manufacture by injection into a mold in two parts on either side of the joint plane 90, the section of the shafted part decreases from the joint plane 9 towards each distal end preferably comprising a pivot 3 and / or a shank. This execution makes it possible to obtain the seamless injection pivot pivots.

La forme du « point d'injection » dépend du moule et de l'installation de production utilisée. Elle est en général circulaire, mais cette exécution n'est pas limitative, le point d'injection peut aussi être un court segment, et sa superficie et sa forme sont liées à l'espace disponible sur le composant 1 dans une zone non fonctionnelle, comme sur une tige d'ancre, ou encore un flasque ou un fond de denture pour un pignon, ou similaire. Le point d'injection est avantageusement logé dans le fond d'une encoche ou d'un évidement.The shape of the "injection point" depends on the mold and the production facility used. It is generally circular, but this execution is not limiting, the injection point can also be a short segment, and its surface and its shape are linked to the space available on the component 1 in a non-functional area, as on an anchor rod, or even a flange or a bottom of teeth for a pinion, or similar. The injection point is advantageously housed in the bottom of a notch or a recess.
