Definitions

  • the invention relates to the field of watchmaking, and more particularly to the field of mechanical watchmaking, where the regulation of the driving energy is provided by a regulating organ.
  • the invention relates, more precisely, to a regulating member provided with a racket system, a clock movement comprising such a regulating member, as well as a timepiece comprising such a clock movement.
  • balance-spring system which includes a flywheel. inertia called balance wheel, associated with a spring in the form of a ribbon wound into a spiral, called hairspring.
  • the hairspring is fixed on a shaft which rotates with the balance wheel; through an external end, the hairspring is fixed on a pin mounted on a pin holder which is itself secured to a fixed bridge (or cock).
  • the rotation of the balance wheel is maintained - and its oscillations counted - by an escapement mechanism comprising an anchor driven by a low amplitude oscillating movement, provided with two pallets which engage the teeth of an escape wheel.
  • an escapement mechanism comprising an anchor driven by a low amplitude oscillating movement, provided with two pallets which engage the teeth of an escape wheel.
  • the escape wheel is subjected to a step-by-step rotational movement whose frequency is determined by the oscillation frequency of the pallet, itself aligned with the oscillation frequency of the sprung balance.
  • the oscillation frequency is approximately 4 Hz, or approximately 28,800 vibrations per hour (A/h).
  • An objective of good watchmakers is to ensure isochronism and regularity of the oscillations (or constancy of the rate) of the balance wheel.
  • this racket system is fixed in rotation relative to the axis of the hairspring.
  • the assembly comprising the bridge, the racket system, the key, the eyebolt holder, the eyebolt, the shaft, the spring and the balance wheel, is commonly referred to as a “regulating organ”.
  • regulatory bodies are proposed by the international application WO 2016/192957 and by the European patent EP 2 876 504 , both in the name of the ETA watch manufacturer.
  • the stops are adjustable to tighten the hairspring in order to eliminate play, particularly during operation of the hairspring.
  • we start by adjusting the rate by moving the racket key then we tighten the hairspring with the key.
  • tightening the hairspring with a racket key risks constraining it and creating chronometric faults, in particular by off-centering the turns.
  • removing the play also modifies the rate, and once the hairspring is tightened, we do not can no longer move the racket key along the hairspring to finish finely adjusting the rate.
  • spiral springs have an integrated adjuster.
  • the rate is not adjusted by modifying the effective length of the spiral spring, but by applying a force or a torque to an elastic element arranged in series with the spiral. It is thus possible to modify the stiffness of the elastic element and consequently of the spiral spring as a whole. Adjusting the stiffness of the spiral spring makes it possible to adjust the operation of the regulating organ.
  • Such a spiral spring provided with an elastic element is for example described in the patent application EP21202213.1 .
