Definitions

  • the present invention relates to a clock wheel, more precisely the fixing of a clock wheel on an axis.
  • Watch wheels such as gear wheels, display discs, etc.
  • a traditional driving that is to say by a plastic deformation of their central opening.
  • 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.
  • 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.
  • FIGS 1 to 4 show different embodiments of a watch wheel according to the invention.
  • 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 °.
  • 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.
  • 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.
