Definitions

  • the present invention relates to a mechanical watch oscillator with flexible guidance, intended to oscillate around a virtual oscillation axis, said oscillator comprising a movable part centered on the oscillation axis, a fixing part intended to be fixed to a first support element, and at least first and second elastic blades connecting the movable part and the fixing part and arranged to exert on the movable part, relative to the fixing part, a restoring torque.
  • Such oscillators also called flexible pivot oscillators, are designed to pivot without a physical axis of rotation, therefore without friction, around a virtual axis of rotation, thanks to an arrangement of elastic parts.
  • pivots with separate crossed blades pivots with non-separated crossed blades or pivots with a remote center of rotation called “RCC” (Remote Center Compliance).
  • RRC Remote Center Compliance
  • oscillators have one or more flexible blades, generally monolithic with the moving part and the fixing part, replacing the hairspring and the physical oscillation axis. These oscillators are particularly interesting in terms of friction reduction.
  • operating stops are generally positioned outside the oscillator in order to be able to act on its moving part.
  • This type of construction with a shaft or a central material element requires the production of blades comprising a recess, a clearance or an eye provided around the shaft or the central material element, allowing the passage of said shaft or material element. central material without contact with the blades.
  • This has the disadvantage of increasing the complexity of designing and manufacturing the blades. This also has the negative effect of reducing the effective length of the blades for a given size, and therefore reducing their stiffness.
  • the present invention aims to remedy these drawbacks by proposing a flexible guided oscillator which is ensured in all radial and axial positions, while retaining the advantages of a flexible guided oscillator.
  • the flexible guided oscillator according to the invention allows, by means of a single tenon integrated in the central hub of the reported balance, to obtain stops in all directions X, Y, Z, over a small diameter, which has the advantage of reducing the friction torque and disturbances.
  • the balance wheel is arranged to constitute the inertial element of the oscillator.
  • This advantageously makes it possible to dissociate the inertia of the oscillator from the stiffness of the elastic blades, thus making it possible to adjust the inertia of the oscillator in an easy and known manner via the reported balance, as for a standard balance, and an embodiment blades to the desired stiffness, without sizing constraints of the blades to obtain the good stiffness/inertia compromise usually sought in standard flexible guided oscillators.
  • the oscillator is such that its mobile part has a shape arranged to define an interior zone empty of any element of material of the mobile part or it does not include a physical shaft passing through the mobile part and/or the elastic blades.
