Definitions

  • the invention relates to a device for applying a torque to a resonator combined with at least two degrees of freedom comprising a first linear resonator in a first direction with respect to which a second linear resonator oscillates in a second direction substantially orthogonal to said first linear resonator. direction, said second resonator comprising a second bearing mass of a pin cooperating with minimum clearance with a groove that includes said mobile.
  • the invention also relates to a resonator combined with at least two degrees of freedom comprising a first linear resonator in a first direction relative to which oscillates a second linear resonator in a second direction substantially orthogonal to said first direction, said second resonator comprising a second mass. carrier of a pin.
  • the invention also relates to a movement equipped with such a combined resonator.
  • the invention also relates to a watch equipped with such a movement.
  • the invention relates to the field of watch mechanisms, and more specifically, mechanical resonators.
  • a combined resonator comprising two flexible guide resonators placed in series with each other, and a mass of which carries a pin which cooperates with a groove of a mobile subjected to a torque.
  • the invention proposes to eliminate the friction between the pin and the groove.
  • the invention relates to a mobile application of a torque to a resonator combined with at least two degrees of freedom comprising a first linear resonator in a first direction with respect to which oscillates a second linear resonator in a second direction substantially orthogonal to said first direction, said second resonator comprising a second mass carrying a pin cooperating with minimal clearance with a groove that includes said mobile, characterized in that said mobile comprises a ring arranged to be mounted on a shaft of such pin or to constitute a said pin, said ring being slidably movable in said groove, and away from lateral surfaces that internally comprises said groove under the effect of magnetic or / and electrostatic repulsion fields.
  • the invention also relates to a resonator combined with at least two degrees of freedom comprising a first linear resonator in a first direction relative to which oscillates a second linear resonator in a second direction substantially orthogonal to said first direction, said second resonator comprising a second mass.
  • carrier of a pin characterized in that said pin is arranged to cooperate with a said mobile according to one of the preceding claims, and constitutes said ring, or comprises a carrier shaft of said ring.
  • the invention also relates to a movement equipped with such a combined resonator.
  • the invention also relates to a watch equipped with such a movement.
  • a resonator combined with at least two degrees of freedom from the series connection of two resonators O1 and 02 with flexible guide each having a mass M1, M2, the M1 of the first resonator O1 being suspended by first flexible blades L1 to a fixed structure P such as a plate.
  • the first resonator O1 oscillates essentially in a first linear direction Y.
  • the first mobile mass M1 of this first resonator O1 serves as anchoring to the second flexible blades L2 of a second resonator 02, which oscillates essentially in a second linear direction X, substantially perpendicular to the first linear direction Y.
  • the second mobile mass M2 of the second resonator 02 comprises a pin 2, which cooperates with a groove 1 which carries a mobile 3 subjected to a torque, typically an escape wheel.
  • the restoring forces are not exactly proportional to the displacements, because the flexible guides L1, L2, used in such a combined resonator are very short, which causes a non-linearity of the force of the spring as a function of the displacement, which introduces a defect of isochronism.
  • the groove 1 which serves as a guide for the pin 2 fixed on the second mass M2 of the second resonator 02 is arranged in a particular way.
  • Pin 2 is a radially magnetized ring 21, or in a particular embodiment illustrated in FIG. figure 2 is a shaft 20 which carries such a magnetic ring 21.
  • the groove 1 is also magnetized so as to always be in repulsion with the ring 21.
  • the groove 1 may either be magnetized over its entire structure, or have sufficient individual magnets, and whose magnetization is oriented in a direction perpendicular to the local tangent to the inner surface of said groove 1.
  • the ring 21 may either be magnetized over its entire structure or have individual magnets in sufficient number and magnetized in a similar manner.
  • the groove 1 and the ring 2 thus form a crank without friction, the major advantages of which are the increase in yield as well as the reduction in wear.
  • the auto-start of the oscillation of the combined resonator is also improved.
  • the magnets can be replaced by electrets.
  • the magnetized zone, respectively electrified, of the groove 1 and / or the ring 21 may result from a treatment of a surface layer of the material, respectively ferromagnetic or electrostatically conductor constituting this groove 1 and / or this ring 21.
  • the invention relates to a mobile 3 for applying a torque to a combined resonator 10 comprising a first linear resonator 10 in a first direction Y with respect to which a second linear resonator 20 oscillates along a second direction X substantially orthogonal to this direction.
  • this second resonator 20 comprising a second mass M2 carrying a pin 2.
  • the mobile 3 comprises a ring 21, arranged to form such a pin 2, or to be mounted on a shaft 20 that includes the pin 2.
  • This ring 21 is slidably movable in the groove 1 of the mobile 3, and away from the side surfaces 11, 12, interior of this groove 1, under the effect of magnetic or / and electrostatic repulsion fields.
  • the periphery 22 of the ring 21 is thus always at a distance from these lateral surfaces 11, 12, which, in a preferred application, are parallel.
  • the groove 1 is substantially radial with respect to the pivot axis D of the mobile 3.
  • the groove 1 comprises at least one concave zone with respect to a radial stem from the pivot axis D.
  • the invention also relates to such a combined resonator 10 equipped with such a mobile 3 with a groove 1 as described above, where the pin 2 is arranged to cooperate with such a mobile 3, and constitutes said ring 21, or comprises a shaft 20 carrying this ring 21.
  • the invention also relates to a movement 100 equipped with such a combined resonator 10, and a watch 200 equipped with such a movement 100.
