Abstract

The wheel (1) has three elastic arms (5) placed in equilateral triangle and defining a triangular opening (7) to receive an axle (8) with circular section. The axle has a diameter greater than that of a circle inscribed in a triangle-shaped outline of the opening such that the axle elastically deforms the arms when it is introduced in the opening. The arms are deformed so that the wheel is maintained on the axle by elastic tightening exerted on the axle by the arms.

Description

La présente invention concerne une roue d'horlogerie, plus précisément la fixation d'une roue d'horlogerie sur un axe.The present invention relates to a clock wheel, more precisely the fixing of a clock wheel on an axis.

Les roues d'horlogeries, telles que les roues dentées, les disques d'affichage, etc., sont généralement fixées sur leur axe par un chassage traditionnel, c'est-à-dire par une déformation plastique de leur ouverture centrale.Watch wheels, such as gear wheels, display discs, etc., are generally fixed on their axis by a traditional driving, that is to say by a plastic deformation of their central opening.

Ce mode de fixation ne convient pas aux roues fabriquées dans une matière fragile telle que le silicium, car ce genre de matière ne se déforme pas plastiquement.This method of attachment is not suitable for wheels made of a fragile material such as silicon, because this kind of material does not deform plastically.

La présente invention vise à proposer un autre mode de fixation d'une roue d'horlogerie sur un axe, convenant notamment aux roues réalisées dans une matière fragile.The present invention aims to propose another method of fixing a clock wheel on an axis, particularly suitable for wheels made of a fragile material.

A cette fin il est prévu une roue d'horlogerie selon la revendication 1 annexée, des formes d'exécution particulières de cette roue étant définies dans les revendications dépendantes.For this purpose there is provided a watch wheel according to claim 1 attached, particular embodiments of this wheel being defined in the dependent claims.

D'autres caractéristiques et avantages de la présente invention apparaitront 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'un disque selon l'invention, tel qu'un disque d'affichage de phase de lune ou du quantième, monté sur son axe ;
  • la figure 2 est une vue de dessus d'une roue dentée selon l'invention, montée sur son axe ;
  • la figure 3 est une vue de dessus d'une roue dentée évidée selon l'invention, montée sur son axe ;
  • la figure 4 est une vue de dessus d'un disque évidé selon l'invention, tel qu'un disque d'affichage de phase de lune ou du quantième, monté sur son axe.
Other features and advantages of the present invention will become apparent from reading the following detailed description with reference to the accompanying drawings in which;
  • Figure 1 is a top view of a disk according to the invention, such as a moon phase display disc or calendar, mounted on its axis;
  • Figure 2 is a top view of a toothed wheel according to the invention, mounted on its axis;
  • Figure 3 is a top view of a recessed gear according to the invention, mounted on its axis;
  • Figure 4 is a top view of a hollow disc according to the invention, such as a moon phase display disc or date, mounted on its axis.

Les figures 1 à 4 montrent différentes formes d'exécution d'une roue d'horlogerie selon l'invention. Dans chacune de ces formes d'exécution (disques 1, 4, roues dentées 2, 3), la roue d'horlogerie comprend une partie centrale élastique, comprenant trois bras élastiques 5 disposés en triangle équilatéral et définis par des lumières 6 et une ouverture centrale 7 formées dans la roue. L'ouverture centrale 7 est destinée à recevoir un axe 8 à section circulaire. L'axe 8 a un diamètre supérieur au diamètre du cercle inscrit dans le contour triangulaire de l'ouverture 7, de sorte qu'il déforme élastiquement les bras 5 lorsqu'il est introduit dans l'ouverture 7, permettant à la roue d'être maintenue sur l'axe 8 par le serrage élastique exercé sur celui-ci par les bras 5. Lorsque la roue est ainsi montée sur l'axe 8, ce dernier est en contact avec les bras élastiques 5 en trois points distincts, répartis à 120°.Figures 1 to 4 show different embodiments of a watch wheel according to the invention. In each of these embodiments (discs 1, 4, toothed wheels 2, 3), the watch wheel comprises an elastic central part, comprising three elastic arms 5 arranged in equilateral triangle and defined by lights 6 and an opening Central 7 formed in the wheel. The central opening 7 is intended to receive an axis 8 of circular section. The axis 8 has a diameter greater than the diameter of the circle inscribed in the triangular contour of the opening 7, so that it deforms the arms 5 elastically when it is introduced into the opening 7, allowing the wheel of 8 when the wheel is mounted on the axis 8, the latter is in contact with the elastic arms 5 at three distinct points, distributed at the axis 8 by the elastic clamping exerted on the latter by the arms 5. 120 °.

Dans la plupart des applications de la présente invention, le serrage élastique exercé sur l'axe 8 par les bras 5 est suffisant pour maintenir la roue dans une position axiale et angulaire fixe par rapport à l'axe 8 pendant l'assemblage et le fonctionnement de la montre. Il est néanmoins possible, dans les cas où cela est souhaité, de prévoir sur l'axe 8 une butée axiale (portée) contre laquelle viendrait s'appuyer la roue. Une rondelle pourrait de plus être appliquée contre la roue et être fixée sur l'axe 8, par exemple par chassage, pour bloquer la roue en appui contre la butée axiale.In most applications of the present invention, the elastic clamping on the axis 8 by the arms 5 is sufficient to maintain the wheel in a fixed axial and angular position relative to the axis 8 during assembly and operation. of the watch. It is nevertheless possible, in those cases where it is desired, to provide on the axis 8 an axial abutment (bearing) against which the wheel would be supported. A washer could also be applied against the wheel and be fixed on the axis 8, for example by driving, to lock the wheel bearing against the axial stop.

La roue d'horlogerie selon l'invention est de préférence réalisée en une seule pièce, et dans une matière à base de silicium. Grâce à sa partie élastique, la roue selon l'invention peut être aisément montée sur son axe et y être maintenue de manière suffisamment ferme, sans rupture du silicium.The clock wheel according to the invention is preferably made in one piece, and in a material based on silicon. Thanks to its elastic part, the wheel according to the invention can be easily mounted on its axis and be held there sufficiently firmly, without breaking the silicon.
