Definitions
- the present invention relates to mechanical oscillators in general and concerns, more particularly, oscillators mechanical watches which comprise a set consisting of a spiral and a balance, compensated in temperature.
- the pendulum must also be compensated heat; what can be achieved, for example, by using a "glucydur” type alloy (alloy of copper and beryllium, also called “glucinium”) or other alloys having a very low coefficient of thermal expansion.
- glucydur alloy of copper and beryllium, also called “glucinium”
- This method is also complicated and no more than the others more traditional methods, does not allow to get rid of others isochronism defects such as those due, for example, to various friction in the oscillator, an imbalance of the balance, a offset of the center of mass of the spiral etc.
- the present invention aims to overcome the disadvantages previous techniques by proposing a hairspring, for oscillator timepiece, whose behavior with respect to variations thermal is such that it allows to maintain the balance-spiral assembly as little as possible of the said variations thermal. More specifically, the spiral of the invention is no only self-compensated but it can be realized in such a way also compensate for the heat drifts of the balance.
- Another object of the invention is to be able to compensate also isochronism defects inherent in the construction the balance-spring.
- the spiral of the invention is made in a crystalline quartz substrate whose cut is chosen so that the whole, constituted by the balance spring and the pendulum, is compensated thermally.
- the shape of the spiral is chosen to compensate for the defects of anisochronism of the balance-spiral assembly.
- the thermal behavior of the quartz spiral springs is essentially related to the inclination of the section with respect to the optical axis Z of the quartz crystal.
- the plane of the hairspring can be identified by a double rotation ZY / ⁇ / ⁇ (notation according to the IEEE standards), where ⁇ is the longitude and ⁇ the colatitude (inclination of the axis of the hairspring relative to to the optical axis Z of the crystal).
- the rigidities of the crystals usually have a nearby thermal inversion point 0 ° K with a negative curvature. They stiffen at low temperature. Their first temperature coefficient at temperature ambient temperature, ie 25 ° C, is therefore generally negative with a negative curvature. It varies from a few tens to a few hundreds of ppm / ° C. Quartz is one of the few crystals allowing, at room temperature, to cancel the first coefficient thermal rigidity by means of the cut, that is to say the orientation of the structure, and even, to make it positive a few tens of ppm / ° C.
- the quartz spiral does not require a pendulum compensated glucydur type. It compensates for the drift thermal of most low-end current balances in stainless steel and, even, to make it, in some ways, more favorable than that of the 32 kHz quartz tuning fork.
- FIGS. 3a to 3.c show the level lines of the graphs of FIG. 2. Considering, in particular, FIG.
- the spirals made in a plate of this type will have maximum elastic symmetry, namely a symmetry with respect to the X plane and a symmetry with respect to the axis of the spiral (Z axis after rotation). These spirals will therefore be better balanced elastically than those made in a double rotation plate and without having a limitation of their heat compensation capacity. It should be noted that the simple rotation can also be performed around the Y axis.
- Figures 5.a to 5.b show the variation, as a function of the angle ⁇ , of the thermal coefficients ⁇ , ⁇ and ⁇ of the stiffness, respectively, for a hairspring having a single rotation cut X / ⁇ .
- the thermal drift of the pendulum depends on the material in which it is made.
- common stainless steels have a thermal coefficient of expansion varying typically between 10 and 15 ppm / ° C, whereas for brass the value of this coefficient is 17 ppm / ° C.
- Figure 6 shows some examples of achievable thermal compensation, for different balance materials, with X / ⁇ single-turn cutting spirals .
- the curves C1 to C3 show the thermal drifts of the frequency of oscillators comprising steel rockers of different types, while the curve C4 corresponds to that of an oscillator with a brass balance.
- the quartz hairspring also makes it possible to compensate for isochronism defects of the oscillator.
- One of the main sources of anisochronism is the variation in the amplitude of the oscillations of the pendulum.
- the variation of the anisochronism can be of the order of several ppm / degree of angle, typically 2 ppm / degree of angle with a typical angle variation of ⁇ 25%.
- a known method to compensate for anisochronism is to act on the curvature of the end of the hairspring near the peak P. This method requires an adjustment step by specially trained persons; which is not optimal in terms of industrialization.
- it is proposed to act on the local stiffness of the turn by modulating the width of its section.
- the modulation has the effect of reinforcing the inertia and the local rigidity of the coil in the opposite sector to the peak.
- the width modulation function of the section is, for example, of the type k .cos ( ⁇ m - ⁇ ), where k is a coefficient of proportionality, ⁇ represents the polar angle in the section considered and ⁇ m the value from the polar angle to the peak.
- k a coefficient of proportionality
- ⁇ represents the polar angle in the section considered
- ⁇ m the value from the polar angle to the peak.
- the anisochronism compensation is about 1 ppm / degree of angle.
- Figure 7 shows a spiral having such a modulation of the width of its section.
- the modulation of the width of the section of the turns may be accompanied by a modulation of the pitch between the turns so that the interval between them at rest remains constant. This last modulation, not shown, avoids sticking between turns during large amplitudes of oscillation.
- the spiral described above may be manufactured by any means known to those skilled in the art for the machining of quartz, such as wet attack means (chemical etching) or dry (plasma attack).
