Definitions

  • the invention relates to a pendulum and its manufacturing method and, more particularly, to a composite pendulum.
  • the regulating member of a timepiece generally comprises an inertia flywheel called a balance wheel and a resonator called a spiral. These pieces are decisive for the running quality of the timepiece. Indeed, they regulate the movement, that is to say that they control the frequency of the movement.
  • the balance and the spiral are different in nature which makes the focus of the regulating organ, which includes the own fabrications pendulum and spiral and their assembly substantially resonance, extremely complex.
  • the pendulum in particular has been manufactured in various materials without the difficulties of isochronism related to the influence of a temperature change of the regulating organ on which it depends, do not disappear.
  • the object of the present invention is to overcome all or part of the drawbacks mentioned above by proposing a composite balance whose characteristics as a function of temperature are more easily adjustable and which is obtained using a manufacturing process which comprises less steps.
  • the invention relates to a composite rocker formed in a layer of silicon-based material and having a hub connected to a serge by at least one arm, characterized in that the serge comprises at least one additional portion of greater density than said silicon-based material for increasing the inertia of said balance.
  • the invention also relates to a timepiece characterized in that it comprises a balance according to one of the preceding variants.
  • the invention relates to a generally annotated method 1 and which is intended to manufacture a balance 45, 45 'for a timepiece movement.
  • the method 1 comprises successive steps intended to form at least one type of composite beam, that is to say which is preferably formed by two different materials, such as for example, silicon and metal.

  • the metal deposited on the substrate 21 has a spacing between each pad 22 adapted to compensate for the thermal expansion of the ring 23 by avoiding transmitting silicon constraints related to these dilations.
  • the cylinder 25 is intended to receive, advantageously, by driving a balance shaft.
  • another disadvantage of silicon lies in its very weak elastic and plastic zones which makes it very brittle.
  • Another characteristic of the invention is therefore to achieve the clamping of the balance shaft not against the silicon but on the inside diameter 24 of the metal cylinder 25 electrodeposited during step 5.
  • the cylinder 25 obtained by electroplating leaves full freedom as to its geometry.
  • the inner diameter 24 is not necessarily circular but, for example, polygonal which could improve the transmission of force in rotation with a corresponding shape of the axis.

  • the arms may be slender in order to allow their axial and / or radial deformation in the event of shock transmitted on the balance 45.
  • the cavity 34 formed in the hub 39 forms with the inner diameter 24 of the metal cylinder 25 a hollow space adapted to receive an axis.
  • material bridges 36 are formed in order to maintain the pattern 35 on the substrate 21.
  • step 9 is simply performed by providing a force to the balance 45 capable of breaking its material bridges 36.
  • This effort may, for example, be generated by machining or manually by an operator.
  • the balance 45 is of the composite type in that it comprises at least two types of material and monoblock in that the element 35 and the elements 23 and / or 25 are inseparable under pain of destruction.
  • the balance 45 comprises a hub 39 connected radially to the seam 37 by four arms 40, 41, 42 and 43.
  • the hub 39 is advantageously also axially connected to the metal cylinder and the seam 37 comprises, on a part of a of its main faces, the crenellated ring 23.
