Definitions

  • the invention relates to an isochronous clock oscillator mechanism with coupled oscillators.
  • the invention also relates to a watch movement comprising at least one such oscillator mechanism.
  • the invention also relates to a watch comprising such a movement.
  • the invention relates to the field of clock oscillator mechanisms, and motion control.
  • the invention proposes to define simplified coupled oscillators, which make it possible to obtain a good stability of the modes, and whose realization is easy.
  • the invention thus relates to an isochronous clock oscillator mechanism with coupled oscillators according to claim 1.
  • the invention also relates to a watch movement comprising at least one such oscillator mechanism.
  • the invention also relates to a watch comprising such a movement.
  • the invention relates to an isochronous clock oscillator mechanism with coupled oscillators, which is realized very simply, by the combination of only two primary oscillators: this oscillator mechanism 100 consists of only a first oscillator 10 and a second oscillator 20.
  • the first oscillator 10 comprises a first elastic return means 11, which is fixed on the one hand to a fixed structure 1 at at least one first anchor 12, and on the other hand to a first mobile 13 pivoting around a first axis D1.
  • the second oscillator 20 comprises a second resilient return means 21 fixed to a second mobile 23.
  • the first oscillator 10 and the second oscillator 20 are coupled to each other by aerodynamic connection between the first mobile 13 and the second mobile 23 and / or by mechanical connection by the second elastic return means 21 which is then fixed to the first mobile 13.
  • first elastic return means 11 is unique
  • second elastic return means 21 is unique
  • first oscillator 10 and the second oscillator 20 are coupled to each other, both by aerodynamic connection between the first mobile 13 and the second mobile 23, and by mechanical connection by the second elastic return means 21 which is fixed to the first mobile 13.
  • the second elastic return means 21 is an elastic flexible guide with thin blades.
  • the first oscillator 10 is of the spiral-balance type
  • the first elastic return means 11 is a first spiral spring fixed to the fixed structure 1 by a first stud constituting the first anchor 12.
  • the second oscillator 20 is also of balance spring type
  • the second elastic return means 21 is a second spiral spring fixed to the second mobile 23.
  • the first resilient biasing means 11, or / and the second resilient biasing means 21 is a thin elastic blade, or the like.
  • the second hairspring 21 is fixed, on the one hand to the serge or to an arm of the first mobile 13 in a second pin 22, and on the other hand to the second mobile 23 which pivots around a second axis D2. And the maintenance of the oscillator mechanism 100 is done on only one of the first mobile 13 or second mobile 23.
  • oscillation maintenance is performed independently on each of the two primary oscillators 10 and 20.
  • the stiffness of the second elastic return means 21 is less than half the stiffness of the first elastic return means 11.
  • the stiffness of the second elastic return means 21 is between 0.30 and 0.40 times the stiffness of the first elastic return means 11.
  • the inertia of the second mobile 23 is less than one third of the inertia of the first mobile 13.
  • the inertia of the second mobile 23 is between 0.20 and 0.30 times the inertia of the first mobile 13.
  • the first mobile 13 and the second mobile 23 are pendulums.
  • the first mobile 13 or the second mobile 23 is a cage of a vortex or a carousel, and the second mobile 23 or respectively the first mobile 13 is a pendulum.
  • the rocker constituting the second mobile 23 or respectively the first mobile 13 is coaxial with the cage of the vortex or carousel constituting the first mobile 13 or respectively the second mobile 23, and is rotated in the cage.
  • the second stud 22 of the second oscillator 20 is attached to an arm or the drum of the cage.
  • the maintenance of the oscillator mechanism 100 is performed by an anchor 3 or a detent cooperating with a small plate attached to the vortex or carousel at its pivot axis.
  • the minimum distance G between large diameter parts, in particular the larger diameter parts, of the first mobile 13 and the second mobile 23 is less than 0.5 mm.
  • This aerodynamic coupling is favorable, even when a main coupling is effected by the second elastic return means 21, because this aerodynamic coupling tends to stabilize the oscillator mechanism 100 on only one of the two modes (in phase or in phase opposition). Aerodynamic coupling exists even with discontinuous surfaces, for example between arms 4 of a vortex or carousel cage on the one hand, and a balance rod 5 on the other hand.
  • the oscillator mechanism 100 comprises means for varying this distance between the first mobile 13 and the second mobile 23, preferably in the range 0.1-0.5 mm.
  • the figure 5 is a diagram roughly illustrating the pace that can take the phase shift curve as a function of time, showing that at a certain value, especially near 0.5 mm, the phase shift comes to stabilize at a substantially constant value.
  • a certain duration ⁇ T of transient regime is necessary before reaching stabilization, for example of the order of 200 seconds for an oscillator consisting of two classic clockwise spirals, beating at 3 Hz, where the pendulums are coplanar and distant of 0.5 mm.
  • the second mobile 23 and the first mobile 13 are coaxial.
  • the second mobile 23 is, at least in projection, inside the first mobile 13.
  • the larger diameter portions of the first mobile 13 and the second mobile 23, which are positioned on two different stages, are substantially the same diameter and substantially opposite one another.
  • the second elastic return means 21 is a second spiral which extends over two floors.
  • the second mobile 23 and the first mobile 13 are positioned side by side and substantially coplanar.
  • the figure 9 shows an aerodynamic coupling with washers or balls, or the like, arranged between two rockers.
  • This solution is also applicable to a variant of the solution of the figure 8 , with a third mobile positioned between the two pendulums. More particularly, at least a third mobile is introduced between the larger diameter portions of the first mobile 13 and the second mobile 23, the third mobile having only the freedom to pivot on itself or to slide in a direction orthogonal to the right which defines the minimum distance between the parts of larger diameters of the first mobile 13 and said second mobile 23. More particularly, the third mobile is fixed to a third elastic return means independent of the first elastic return means and the second means of elastic recall to define a third oscillator coupled by aerodynamic link to the first oscillator 10 and the second oscillator 20.
  • the invention also relates to a watch movement 200 comprising at least one such oscillator mechanism 100.
  • the invention also relates to a watch 1000 comprising such a movement 200.
