Definitions

  • the invention relates to a sprung-balance assembly whose balance has means for adjusting the inertia.
  • the invention also relates to a watch movement comprising such a system and a timepiece equipped with such a movement.
  • the invention particularly aims to overcome the various disadvantages of these known techniques.
  • an object of the invention is to provide a pendulum for obtaining a compact watch movement.
  • Another object of the invention is to provide a balance spring system allowing easy access to the flyweights for adjusting the inertia after the casing.
  • the invention also aims, at least in a particular embodiment, to provide a balance spring system that is simple to implement and inexpensive.
  • a balance-balance system comprising at least one balance oscillating about a pivot axis via a control shaft.
  • balance wheel mounted between a plate and a bridge (9) and aligned on said pivot axis, and at least one spiral of which an inner turn is fixed to said balance shaft or to a ferrule mounted integral with said balance shaft and an outer turn of which is fixed to a pin integral with the bridge carrying said shaft, said balance having a balance hub, a serge, at least one arm connecting said hub to said serge, a front face having a recess and a rear face, said at least one arm comprising a housing for receiving and maintaining a feeder, and said hairspring being mounted facing the front face of the balance.
  • said flyweight is mounted on the side of the rear face of the balance, on said at least one arm of said balance, and in that the distance between the bottom of the core of the front face of the balance and the balance is within a predetermined range of 0.05mm to 1.50mm
  • the invention also relates to a watch movement comprising a balance-balance oscillator system according to the invention.
  • the invention also relates to a timepiece comprising a watch movement according to the invention.
  • the object of the present invention by its different functional and structural aspects described above, makes it possible to obtain a clockwork movement comprising a balance-spring system whose access to the means for adjusting the inertia is particularly easy. .
  • the invention thus relates to a sprung balance-balance system, intended to be incorporated in an oscillating mechanism within a watch movement, and comprising at least one rocker 1 oscillating about a pivot axis P via a balance shaft 40 aligned on the axis P and at least one hairspring 2.
  • the rocker shaft 40 is mounted between a plate 13 and a bridge 9, the rocker shaft 40 having at each of its ends a tapered pivot 41 to allow the rocker shaft 40 to pivot about the axis pivoting P by limiting the friction.
  • An inner turn (not visible in the figures) of the hairspring 2 is fixed to the balance shaft 40 or to a shell 7 which can be integral with the hairspring 2 mounted integral with the balance shaft 40 and an outer turn 21 of the hairspring 2 is fixed to a stud 8 secured to a bridge 9.
  • the balance 1 comprises a hub 3 carrying the balance shaft 40, a serge 4, at least one arm 5 connecting the hub 3 to the serge 4, a front face 10 having a core 11 and a flat rear face 12 which can also be embedded.
  • the arm 5 comprises a housing 6 for receiving and holding at least one feeder 30, and the hairspring 2 is mounted opposite the front face 10 of the rocker 1 receiving the casing 11.
  • the rocker 1 comprises rigid parts constituted by the hub 3, the serge 4, and the arm 5 connecting the serge 4 to the hub 2.
  • the housing 6 is delimited, on the one hand by a rigid portion of the balance 1, and on the other hand a portion 61 elastically deformable.
  • the arm 5 comprises a housing 6 for receiving and pinching in the position of a rod 32 of a flyweight 30.
  • This weight 30 comprises a head 31 having handling means such as a control profile 33 arranged to cooperate with a tool, such as a screwdriver.
  • a tool such as a screwdriver.
  • the rod 32 of the weight 30 extends the head 31, which is of greater diameter than that of the rod 32.
  • the diameter of the rod 32 of the weight 30 is chosen greater than the width of the housing 6 so that the rod 32 is retained by the portion 61 elastically deformable, the portion 61 exerting a restoring force.
  • the length of the rod 32 does not exceed the thickness of the arm 5, so that the rod 32 is not protruding and thus optimize the arrangement of parts within the movement to gain compactness.
  • This simple configuration of a feeder 30 consisting solely of the head 31 and the rod 32 is favorable for mounting the feeder on the balance 1 from the bottom of the latter.
  • the weight 30, once pinched in the housing 6, is angularly adjustable by means of a tool without being disturbed by the spiral 2 or by the limited space available.
  • the weight 30 comprises an unbalance made by means of a flat portion 34 made on the head 31, as visible on the figure 1 a, to allow the inertia adjustment of the balance 1.
  • the weight 30 is mounted on the side of the rear face 12 of the balance 1, the head 31 resting against the rear face 12 of the balance 1 under the arm 5, the distance between the bottom of the face of the yoke before 10 of the balance 1 and the balance spring 2 is in a range V predetermined between 0.05mm and 1.50mm. More preferably, the predetermined interval V is between 0.10mm and 0.70mm. Such an arrangement provides a compact arrangement and thus reduce the size of the watch movement.
  • the rod 32 is flush with the bottom of the core 11 of the front face 10 of the rocker 1 so that the core 11 does not have a projecting element, the stud 8 can then be arranged at most near the serge 4, the piton 8 can even be closer to the bottom of the hole 11.
  • the arm 5, the serge 4 and the hub 3 form a single piece element, the rocker 1 can be made of a metal material.
  • the invention also relates to a watch movement and a timepiece equipped with a balance spring system according to the invention.
