Definitions
- the present invention relates to a spiral balance for a balance-sprung oscillator of a timepiece which can be produced, in particular, in a low-density material such as silicon, diamond or quartz, as well as a process for the manufacture of such a hairspring.
- the aforementioned low-density materials make it possible to give the hairspring a complex geometry by micro-fabrication techniques, for example by masking and etching a silicon wafer.
- the chronometric performance of the hairspring depends directly on its mass, because the mass of the hairspring contributes, during the expansion and the contraction of the latter, to the forces exerted on the pivots of the balance.
- EP 1 921 518 describes an assembly element that can equip a timepiece.
- This element comprises elastic rectilinear blades and openings (clearance lights) separated by bridges of material. It aims to improve the strength of its clamp against a tree.
- European patent application no. EP 2 233 989 filed before but published after the filing of the present application, relates to a spiral spring which may comprise on part of its last turn, openings formed by a first strand located on the normal curve of this turn and a second strand positioned substantially parallel, these strands being rigidly connected by bridges.
- This arrangement aims to bring the center of action of the spiral in correspondence with the center of the balance associated with the spiral, to correct the spiral of its non concentric development (cf paragraph [0014] and figures).
- the object of the present invention is to reduce the weight of a hairspring for a timepiece, while keeping a rigidity equivalent to that of a solid hairspring.
- the subject of the present invention is a spiral for a balance-balance oscillator comprising at least one blade whose cross section has a thickness and a height, this blade forming turns, at least one of which is provided with a plurality openings that extend in the direction of the height of the blade and alternate with bridges, the spiral is distinguished in that these openings are distributed at least over the entire length of the coil or openwork turns (s).
- the mass of the blade is reduced and it follows an improvement of the isochronism of the balance-balance control member.
- the openings are distributed over the entire length of the blade.
- the openings can be distributed regularly, either with a constant distance between bridges, or with an angular pitch between constant bridges, or irregularly, with an angular pitch or a distance between variable bridges, over the entire length of the or the turns or any the blade.
- the openings and the thickness of the blade are dimensioned so that the rigidity of the blade is the same as that of a reference blade of determined section and without openings, which is advantageous for the behavior of the spiral during shocks, given the decrease in its mass.
- the openings have an elongated shape and the blade has two equidistant portions integral with one of the other and separated by the openings.
- the openings are of circular or elliptical shape.
- the two equidistant portions each have a thickness less than half the thickness of the reference blade and are separated at the openings by a distance greater than half the thickness of the the reference blade without openings.
- the thicknesses of the two equidistant portions of the blade are each equal to one quarter of the thickness of the reference blade and the total thickness of the blade is equal to 1.05 times the thickness of the reference blade without in days.
- the bridges are regularly located along the blade with a constant angular spacing.
- the angular difference between the bridges alternating with the openings is chosen between 1 ° and 360 °.
- the angular difference between the bridges is 30 ° on the inner turns and 15 ° on the outer turns.
- the bridges are regularly located along the blade with a constant distance between bridges.
- the blade is made of silicon, diamond or quartz.
- the blade is made of a metal alloy, for example a Ni-based alloy.
- the blade has a constant thickness along the turns.
- the blade has a variable thickness along the turns.
- the blade comprises a core and a layer of outer material enveloping the core, configured such that the ratio between the dimensions of the core and the outer material layer remains constant along the blade.
- the core of the blade is silicon and the outer material layer is silicon dioxide SiO 2 .
- the invention also relates to a method of manufacturing such a spiral.
- the spiral blade is intended to be connected to a timepiece balance (not shown) and it elastically deforms concentrically during its contraction and expansion, consecutive oscillations spiral balance.
- a blade 1 or ribbon of a spiral of the state of the art has a cross section of rectangular shape, height h and thickness e, and has an inner end connected to a ferrule (not shown) for attachment to the shaft of a pendulum and an outer end connected to a fixed attachment point (not shown).
- the monobloc blade 1 is referred to as reference blade 1 without openings.
- the hairspring is made of a low-density material such as silicon, diamond or quartz by micro-fabrication techniques making it possible to produce complex blade geometries, for example by masking, etching and cutting a plate. of silicon.
- the directions respectively axial, radial and angular are used by convention to simplify the description and correspond substantially to the directions extending respectively along the height of the cross section, the thickness of the cross section and each turn of the blade.
- the spiral according to the invention shown in figures 2 and 11 comprises a blade 2 forming turns which have gaps 3 spaced regularly over all their lengths, in the thickness of the blade, so as to reduce the mass / stiffness ratio, and ultimately to reduce its mass.
- the openings 3 pass axially through the blade 2, in the direction of the height of its cross-section between two equidistant portions 4, which is better illustrated on FIG. figure 4 .
- the openings 3 preferably have an elongated shape. They are located each between equidistant portions 4 of the blade 2 alternating with bridges 5 joining the two equidistant portions 4.
- the bridges 5 are evenly distributed along the blade 2 at an angular distance ⁇ of 30 °, the arc length of the openings 3 increasing outwardly of the blade 2 at each turn of the spiral turn.
- the angular distance ⁇ between the bridges 5 can be chosen between 1 ° and 360 °.
- This angular difference ⁇ can be chosen different for the inner turns and for the outer turns, as illustrated in FIG. figure 10 where it is equal to 30 ° for the inner turns and 15 ° for the outer turns. It can also vary continuously, for example to maintain a distance between two bridges along turns substantially constant d.
- the arrangement of the bridges 5, the dimensioning of the openings 3 and the thickness of the portions 4 are configured so as to ensure that the blade 2 of the figure 2 the same rigidity as that of the reference blade 1 without openings.
- the blade 2 of the spiral according to the invention is comparable to a beam of height h 'and of total thickness e' formed of two equidistant and symmetrical portions 4, d ' thickness e "and separated by an aperture 3 passing through two opposite planar faces 7 of the portions 4.
- the difference in market between positions, on the figure 5 is typically 3-4 s / d between 200 ° and 300 ° amplitude with a value of 3.62 s / d at 250 ° for the blade 1 while it is, on the figure 6 , 1-2 s / d between 200 ° and 300 ° amplitude with a value of 1.82 s / d at 250 ° for the blade 2.
- the blade 2 of the hairspring according to the invention thus makes it possible to significantly reduce the operating deviations of the regulating member by dividing them by two in this example.
- the figure 7 illustrates the maximum operating distance ⁇ M obtained on the one hand with a blade 1 (curve denoted "1") of a thermocompensated balance of 14 turns (14 turns), 5 mm in diameter, a constant thickness of 44 ⁇ m and a no 136 ⁇ m, other part with a blade 2 according to the invention of a heat-compensated hairspring with a number of turns, a diameter and an equivalent rigidity, but with a mass of 0.5, respectively 0.75 times the mass of the hairspring with the blade 1 .
- the maximum gimbal clearance is substantially reduced by 0.5 s / d at 200 ° of amplitude, and shows a comparable decrease of gait irrespective of the amplitude of the balance-balance oscillator.
- the conformation of the openings 3 of the blade 2 of the spiral according to the invention is also advantageous for the thermo compensation of a blade of variable thickness.
- thermocompensating materials other than Si are known to those skilled in the art.
- the ratio between the dimensions the core 12 and the layer 13 of outer material is advantageously constant all along the hairspring, even in the parts of the blade 2 showing a large variation in total thickness e ', as illustrated in FIG. figure 9 .
- the thickness of SiO 2 necessary to achieve the thermo compensation is reduced compared to the thickness required for the reference blade 1 without openings .
- the blade 2 according to the invention has a lower mass while keeping the same rigidity as that of the reference blade 1 without openings, it will be less sensitive to shocks.
- the present invention could also be applied to a spiral with turns of varying pitch and thickness, such as those described in the application EP 2,299,336 . It is also conceivable to vary the thickness of the portions and their spacing along the blade. It is also possible that the two portions show different thicknesses, or use more than two portions connected by bridges. The spacing between the bridges can also be varied. In addition, the thicknesses of each of the two portions of the blade can also vary along the blade, as their spacing. In addition, the two blades can have different thicknesses and the ratio of these thicknesses can evolve along the blade.
- the figure 12a is a spiral whose blade portions have a thickness that varies between the bridges, which aims to maintain the maximum constant stresses in the section portions and minimize the risk of rupture of the blades.
- the figure 12b represents a polygonal shape and the figure 12c a wavy shape, these forms to adjust the compressibility of the inner portion, the side that works in compression during bending, and thus influence the linearity of the elastic behavior. This is to avoid strongly non-linear effects due to buckling of the inner part.
- These shapes and variations can, of course, evolve along the blade, each blade portion between two bridges may have its own structure.
- bridges that are not oriented perpendicular to the blade, such as the inclined bridges visible on the bridge.
- bridges that are not oriented perpendicular to the blade and that have the effect of increasing the rigidity of the blade, as on the figure 12f or on the figure 12g .
- the shape, size and orientation of the bridges can thus have a more or less important influence on the blade stiffness. These parameters are also to be taken into account in case of optimization of the shape of the blade in order to obtain a concentric development of the hairspring and good chronometric performances of the balance-hairspring.
- the spirals according to the invention are advantageously produced by microfabrication techniques, such as the DRIE ("Deep Reactive Ion Etching") method for Si, quartz or diamond, or the UV-LiGA process ("Lithography, Galvanoformung, Abformung For Ni or NiP alloys. It is also possible to use more conventional methods such as laser machining, water jet or EDM if the dimensions of the elements and the required tolerances allow it.
- DRIE Deep Reactive Ion Etching
- UV-LiGA process Lithography, Galvanoformung, Abformung For Ni or NiP alloys.
- the hairspring according to the invention could have several blades 2 angularly offset which could possibly be interconnected by an intermediate ring, as described and illustrated in the patent application.
- EP 2 151 722 could be interconnected by an intermediate ring, as described and illustrated in the patent application.
- the present invention could also be applied, in the field of watchmaking, to other flexible elements such as springs, the arms of a mobile, the flexible parts of a game-catching gear or a ferrule.
