Definitions

  • the present invention relates to a spiral intended to be associated with a balance to form an oscillator (regulating member) of a watch movement.
  • the present invention aims to remedy this drawback or at least to mitigate it, and proposes for this purpose a hairspring according to claim 1 and a spiral manufacturing method according to claim 9.
  • FIG. 1 is a top view showing a hairspring according to a particular embodiment of the invention, with its shell, and a clamp for fixing the outer end of the hairspring;
  • Figure 2 is a radial section through three adjacent turns of the spiral shown in Figure 1.
  • a hairspring 1 is intended to be mounted on a balance shaft A by means of a shell 2 to form with the balance the oscillator of a watch movement.
  • the hairspring 1 consists of a blade 3 wound in a spiral from an inner end 4 joined to the ferrule 2 to an outer end 5 to be fixed to the frame of the movement through one or more organs.
  • the outer end 5 of the blade 3 is extended by a rigid attachment portion 6 which is held by a clamp 7 mounted on the frame of the movement, as described in EP 178061 1 of the applicant.
  • the outer end 5 could however be fixed to the frame in another way, for example by means of a traditional stud.
  • the assembly comprising the blade 3, the ferrule 2 and the rigid fixing portion 6 may be monolithic, as shown, and be made of silicon by deep reactive ion etching (DRIE).
  • the average plane in which the blade 3 is wound is designated by P in FIG. 2.
  • This average plane P is located at mid-height between an upper surface 8 and a lower surface 9 of the blade 3, surfaces 8, 9 which typically are flat and parallel.
  • This mean plane P passes through the two flanks 10, 1 1 of the blade 3 which each connect the upper surface 8 to the lower surface 9.
  • These two flanks 10, 1 1 are rectilinear in radial section, that is to say in a plane containing the imaginary oscillation axis O of the spiral 1, and have a low roughness.
  • the flanks 10, 1 1 of the blade 3, in radial section are not perpendicular to the average plane P but are each inclined by a draft angle a (visible only in FIG. equal to 2.5 °, preferably greater than or equal to 3 °, more preferably greater than or equal to 4 °, more preferably greater than or equal to 5 ° and typically between 2.5 ° and 20 °, more particularly between 2.5 ° and 6 °, giving the radial section of the blade 3 a trapezoidal shape.
  • a draft angle a visible only in FIG. equal to 2.5 °, preferably greater than or equal to 3 °, more preferably greater than or equal to 4 °, more preferably greater than or equal to 5 ° and typically between 2.5 ° and 20 °, more particularly between 2.5 ° and 6 °, giving the radial section of the blade 3 a trapezoidal shape.
  • the flanks 10, 1 1 thus form, in radial section, an angle ⁇ greater than or equal to 5 °, preferably greater than or equal to 6 °, more preferably greater than or equal to 8 °, more preferably greater than or equal to at 10 °, and typically between 5 ° and 40 °, more particularly between 5 ° and 12 °.
  • Such angles can be obtained by adjusting the parameters of the DRIE method, in particular the ratio between the etching and passivation times.
  • each flank of the monolithic assembly 2, 3, 6 can be tilted from the draft angle a.
  • the present invention does not exclude, however, that the draft angle has differed from one flank to another.
  • the turns of the hairspring 1 can move radially and touch.
  • the contact between the turns can not be plane, unless the turns twist.
  • the absence of plane contact over a sufficient height prevents the turns from adhering to each other.
  • the higher the draft angle the more difficult it is for the turns to twist sufficiently.
  • the risk of gluing the turns together is thus reduced.
  • the present invention also reduces the risk of bonding between the first turn and the ferrule 2 and between the last turn and the clamp 7 or other fastener to the frame of the movement, in case of shock or mishandling.
  • Another advantage of the hairspring according to the present invention is that, thanks to its straight flanks 10, 11, it is relatively easy to manufacture.
  • the present invention is applicable to other materials than silicon, for example silicon carbide, boron nitride, glasses, ceramics or diamond, and other manufacturing processes.
  • the DRIE engraving for example laser machining, molding, etc.
  • the spiral according to the invention may be coated with one or more layers, for example a silicon oxide layer in the case of a silicon spiral.
