Definitions

  • the invention relates to a paired balance spring - spiral resonator and more specifically a spiral formed from monocrystalline quartz.
  • the document EP 1 519 250 describes the manufacture of a monocrystalline quartz spiral. However, a spiral quartz monocrystalline is not easy to match in practice.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing an improved pairing of a quartz spiral with its balance.
  • the invention relates to a resonator comprising a spiral formed in a monocrystalline quartz crystal of x, y, z crystallographic axes, the x axis being the electric axis and the y axis the axis. mechanical, and cooperating with a balance characterized in that the coefficient of expansion of the balance is between +6 ppm. ° C -1 and +12 ppm. ° C -1 for a cutting angle of the spiral with respect to the axis z of said monocrystalline quartz crystal between -5 ° and + 5 ° in order to pair the balance with the hairspring.
  • the invention relates to a resonator 1 of the balance 3-spiral type 5.
  • the balance 3 and the spiral 5 are preferably mounted on the same axis 7.
  • E the Young's modulus of the spiral, h its height, e its thickness and L its developed length.
  • the thermal dependence also includes a possible contribution of the maintenance system such as, for example, a Swiss lever escapement (not shown) cooperating with the ankle 9 of the plate 11 also mounted on the axis 7.
  • a Swiss lever escapement (not shown) cooperating with the ankle 9 of the plate 11 also mounted on the axis 7.
  • the invention more particularly relates to a resonator 1 in which the hairspring 5 is formed from a quartz monocrystal of crystallographic axes x, y, z, the x axis being the electric axis and the y axis. the mechanical axis.
  • the height h of the turns has substantially the same orientation as the crystallographic axis z. More precisely, the height h forms, with the axis z, an angle ⁇ which can be positive or negative. The modification of this angle 0 makes it possible to vary the characteristics of the spiral 5 without having to modify the geometry.
  • a coefficient of expansion ⁇ b of the balance 3 should be substantially equal to +9 ppm. ° C -1 to obtain a substantially equal thermal coefficient at + 0.06 Sj -1 . ° C -1 which is well below the COSC conditions equal to ⁇ 0.6 sj -1 . ° C -1 .
  • the expansion coefficient ⁇ b of the balance 3 is between +6 ppm. ° C -1 and +12 ppm. ° C - 1 .
  • the balance 3 may notably comprise titanium and / or durimphy (symbol AFNOR: Z2NKD 18-09-05) and / or platinum.
  • durimphy may be slightly sensitive to magnetic fields depending on its temperature of return.
