Definitions

  • the present invention relates to a device for fixing a lift on a anchor of an escapement of a watch movement, and more particularly a such a device free from the use of shellac.
  • the present invention also relates to a method of fixing a lift on an anchor of a escape of a clockwork movement.
  • exhaust means the mechanism placed between the watchmaking movement and its regulator, for example the pendulum of the watch movement, this exhaust serving to maintain the oscillations of the pendulum and to control the speed of the wheel.
  • the exhaust 1 comprises an escape wheel 2, an anchor 4 and a large plate 6 carrying an ankle 8 and a small plate 10 provided with a notch 11 carried by the axis of the balance 12.
  • the anchor comprises two levées such as 14 cooperating with the wheel 2 and a rod 16 ending by a fork 17 with three teeth cooperating with the large and small trays 6 and 10 respectively.
  • These lifts 14 are each secured in a housing or appropriate cell 18 provided in the branches such as 19 of the anchor 4.
  • the fork 17 comprises two outer teeth such as 20 which cooperate with the ankle 8 while the inner tooth or dart 22 cooperates with the small plate 10 and prevents inadvertent overturning of the anchor 4 during the oscillation additional balance (not shown).
  • the movements of the anchor 4 are limited by pins or stops such as 24 against which the rod 16 come knocking.
  • the rod 16 presses against one of the two pins 24 of limitation.
  • a tooth 2d of the escape wheel 2 is pressed against one of the lifts 14 as shown in FIG. inner tooth 22 of the fork 17 is disengaged from the notch 11 so that the pendulum is released and travels a distance in the counter-clockwise direction S, the amplitude is determined by the accumulated energy.
  • the pendulum then goes back into clockwise to clear the lift 14 of the tooth 2d.
  • the anchor travels empty a small distance, called lost way, until the rod 16 abuts against the pin 24.
  • Shellac is an organic glue which has the advantage of being able to be melted at any time temperature in a thick and sticky liquid and thus allow easy adjustment and precise position of the lifts.
  • shellac has some disadvantages.
  • shellac is very sensitive to the chemical washing agents of movements and therefore release shellac particles which come to settle at various places of the movement. Depending on the location, these particles can significantly affect the performance of the exhaust and by consequently disrupt the movement's march.
  • the main purpose of the invention is thus to overcome the disadvantages of the art mentioned above by providing a device for fixing a lift on a Anchor which ensures a reliable fixation while avoiding the use of shellac or any other glue while allowing easy and precise adjustment the penetration of the lift in the toothing of the escape wheel.
  • the invention also aims to provide such a device that is easy to implement and allow a precise and economical fixing.
  • the subject of the invention is a device for fixing a lift on an escape anchor comprising at least one housing adapted to receive said lifting, characterized in that the portion of the anchor comprising said housing or the whole anchor is made of a shape memory alloy able to undergo a reversible transformation of a phase austenitic crystallographic phase crystallographic martensitic.
  • shape memory alloys have the property of being able to undergo a reversible transformation of a high crystallographic phase so-called austenitic temperature at a low temperature crystallographic phase so-called martensitic and so being able to be educated to take in some temperature conditions of the configurations corresponding to states stored.
  • austenitic temperature at a low temperature crystallographic phase so-called martensitic
  • martensitic so-called martensitic
  • the portion of the anchor comprising the housing receiving the lift so that this housing does not substantially lift the lift and allows a displacement of the lift in the latter when the anchor is brought to an determined temperature at which its crystallographic phase is in the state austenitic and that it firmly squeezes the lift when said portion of the anchor is in the martensitic crystallographic phase at room temperature.
  • it will suffice to heat the portion of the anchor comprising the housing at the temperature determined, which will depend on the composition of the alloy, to proceed to the introduction and adjustment of the lifting in the housing, then to bring back the anchor in its martensitic crystallographic phase at room temperature or operation.
  • the portion of the anchor comprising the housing receiving the lift so that this housing does not substantially lift the lift and allows a displacement of the lift in the latter when the anchor is in its phase martensitic crystallographic structure and that it tightens the lift when said portion of the anchor is in the austenitic crystallographic phase while it is at the ambient temperature.
  • it will be sufficient to cool the portion of the anchor having the housing at a predetermined temperature below the temperature ambient, which will depend on the composition of the alloy, to proceed to the introduction and adjustment of the lifting in the housing, then to bring back the anchor lower than the ambient temperature to bring the anchor back into its phase austenitic crystallographic.
  • FIGS. 2a and 2b show the portion 4a of an anchor 4 comprising the housing 18 receiving the lift 14.
  • This portion 4a is made of an alloy to shape memory capable of undergoing a reversible transformation of a phase crystallographic austenitic with a martensitic crystallographic phase when it passes beyond respectively below a temperature of determined transformation.
  • Portion 4a may be made of a Ni-Ti, Ni-Ti-X alloy, or Cu-AI-X, X belonging to the set of metal dopants.
  • These alloys and their methods of education are well known and are particularly described in a NASA article, SP 5110 published in 1972 and titled "55 Nitinol the alloy with a memory: its physical metallurgy properties and applications ".
  • the shape memory alloy chosen to produce the portion 4a of the anchor will exhibit a martensite / austenite transformation temperature in outside the range of use temperature of the anchor that typically extends between - 20 ° C and 50 ° C.
  • this range of temperatures we will call this range of temperatures by "ambient temperature” in the following description.
  • the housing 18 is formed in an extreme part branch 19 by a notch delimited by jaws 32, 34.
  • jaws 32 and 34 are configured to close in the direction of the housing 18 and thus tighten the lift 14 disposed in the latter.
  • the jaw 32 is fixed and the jaw 34 is movable between a first position said loosened ( Figure 2a) in which the lift can be introduced into the housing 18 and moved in that, in particular for the purpose of adjusting the penetration P and a second position called tight (Figure 2b) in which the jaws tighten secure the lift and immobilize it in the housing 18.
  • the jaw 32 comprises two clamping surfaces 32a, 32b planes and aligned for cooperating with a face 14a of the lift and the jaw 34 comprises a clamping surface 34a substantially opposite the clamping surfaces 32a and 32b, the clamping surface 34a being intended for cooperate with a face 14b of the lift, opposite the face 14a.
  • the surfaces of 32a and 32b extend on either side of a clearance 33 formed in the fixed jaw 32.
  • the clamping surface 34a extends substantially between the two clamping surfaces 32a and 32b. The jaws 32 and 34 thus allow a stable clamping in three lifting points in his dwelling.
  • the jaw 34 is in the tight position.
  • the portion of the anchor 4a is made of a shape memory alloy having a martensitic crystallographic phase with ambient temperature.
  • a rise in temperature beyond the martensite / austenite transformation temperature induces deformation of the jaw 34 bringing the latter into the loosened position.
  • the jaw remains in its loosened position so that the lift 14 can be easily introduced into the housing 18 and its position in the housing can be adjusted to to obtain the desired penetration P.
  • this adjustment just allow the portion 4a of the anchor to return to room temperature to bring the jaw 34 in the tight position. If necessary readjust the P penetration or replace the lift, simply bring the anchor portion 4a beyond the transformation temperature.
  • Ni-Ti alloy having the range of martensite / austenite transformation temperature between 80 ° C and 100 ° C
  • the education of the anchor to obtain the opening of the clamp by heating the anchor above the martensite / austenite transformation temperature is typically as follows.
  • (b) The anchor is heated above its temperature martensite / austenite transformation to bring the anchor into the austenitic phase.
  • the anchor is then allowed to cool to room temperature which brings anchor in its martensitic phase.
  • the jaw 34 At this temperature, the jaw 34 to bring it in a tight position ( Figure 2b).
  • (e) We heat up again the anchor above its martensite / austenite transformation temperature and one then note that the anchor resumes a shape corresponding to the loosened position 34. Steps (b) to (e) of the education process may be repeated several times.
  • the portion of the anchor 4a is made into a shape memory alloy having austenitic crystallographic phase at ambient temperature.
  • a lowering of the temperature below the martensite / austenite transition temperature induces a deformation of the jaw 34 bringing the latter into the loosened position.
  • the jaw remains in its loosened position so that the lift 14 can be easily introduced into the housing 18 and its position in the housing can be adjusted to to obtain the desired penetration P.
  • just allow the portion 4a of the anchor just allow the portion 4a of the anchor to return to room temperature to bring the jaw 34 in the tight position.
