    Description
    Domaine de l’invention [0001] L’invention concerne une rondelle d’équilibrage, agencée pour son maintien sur une tige, à relief ou lisse, que comporte un balancier d’horlogerie ou une masselotte rapportée sur un tel balancier.
    [0002] L’invention concerne encore un balancier d’horlogerie comportant, solidaire de sa serge ou d’une masselotte rapportée sur sa dite serge, au moins une tige s’étendant selon un axe de tige et apte à porter une telle rondelle.
    [0003] L’invention concerne une pièce d’horlogerie comportant au moins un tel balancier.
    Arrière-plan de l’invention [0004] Les réglages d’équilibrage et d’inertie d’un balancier d’horlogerie conditionnent la fréquence d’oscillation et la régularité de la marche.
    [0005] Traditionnellement ces réglages sont faits par déplacement de masselottes, vis, écrous, ou par déformation de bras du balancier. On connaît encore des ajouts de matière par imprimante à jet d’encre, ou, à l’inverse, des ablations de matière par laser, ou encore des déplacements de matière, comme dans les demandes EP 11 739 016.1 et EP 14 173 409.5 du même déposant. On connaît aussi des réalisations en silicium ou similaire, avec ou sans insert, comme dans les documents EP 10 170 007.8 et EP 11 731 310.6 de la Société NIVAROX-FAR.
    [0006] The difficulty is twofold: the attainment of the right value, as a function of the balance spring to which the balance is associated, and the fineness of the adjustment. It is estimated that, in the best case, a setting of weights can be used to adjust the step with an accuracy of a few tens of seconds per day, or at best a few seconds per day per turn of the screw / nut for two sets of nuts traditional. As a result, a setting to the second / day remains very delicate, as this is only a few degrees, or tenths of a degree, on a screw / nut assembly. SUMMARY OF THE INVENTION [0007] To refine the possibilities of adjustment, the invention exploits a principle with added washers has been thought. These added washers are elaborated, in a particular way, much lighter than the known screws, And therefore have a limited influence on the inertia and hence on the variation in walking. It is then possible to have an adjustment system of the order of a few tenths of a second per day per revolution of the washer for two washers, for example.
    [0008] Thus, the invention relates to a washer according to claim 1.
    [0009] The invention also relates to a clock beam according to claim 16.
    The invention relates to a timepiece comprising at least one such balance.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention relates to a balancing washer 1, designed for its retention on a rod 3 or 30, which comprises a watch beam 2 or a weight 4 attached to such a balance 2 .
    [0013] This rod may be of various types: FIGS. 1 to 19 and 23 relate to a raised rod 3, while FIGS. 20 to 22 illustrate a smooth rod 30, which will be explained later.
    By "relief rod" is meant here a substantially linear rod which extends along a rod axis A and has a succession of hollow profiles 31 separated by vertices 32. It may be a threaded rod, An annular rod, or else have a more varied profile as in FIG. 19.
    According to the invention, the washer 1 is a substantially annular elastic washer, around an orifice 10 arranged to at least partially surround such a relief rod 3, and comprises at least one resilient skirt 11, which is arranged to To permit introduction or extraction of this washer 1 relative to a corresponding relief rod 3 under the action of a radial or / and axial force and to ensure clipped hold on this relief rod 3 in the absence of d And this washer 1 comprises an angular gripping or / and indexing means 6, star, notch, pin, or the like, located on a peripheral edge 7 included in this washer 1, so as to allow An adjustment by a manual or robotic tool.
    [0016] The washer 1 is substantially annular around the orifice 10 around a washer axis D.
    The elastic skirt 11 preferably ensures this clipped hold with a pinching torque which is greater than a predetermined threshold value VSC.
    In a simple and economical embodiment, suitable for manufacturing in "Liga" or "MEMS" micromachining, the washer 1 is substantially planar.
    In the illustrated, non-limiting embodiments, the washer 1 comprises at least one opening 5 which is substantially radial with respect to the washer axis D and delimited by a first lip 51 and a second lip 52. The spacing In the free state between these two lips 51 and 52 is smaller than the smallest radial dimension of the relief rod 3 with which the washer 1 is arranged to cooperate. At least one of the first lip 51 and the second lip 52 is an elastic lip. The opening 5 is designed to allow an axial or / or radial insertion or extraction, with respect to said rod axis A, under the action of an axial or / and radial force with respect to the rod axis A, Of the washer 1 with respect to this raised rod 3.
    [0020] Une introduction radiale est avantageuse quand, dans une configuration selon la fig. 5, le balancier 2 est déjà équipé d’une masselotte 4, soit fixée sur une tige à relief 3, soit comportant une tige à relief 3 et fixée sur la serge 20 du balancier, ou sur un de ses bras, et on souhaite insérer la rondelle 1 de micro-ajustement entre la masselotte 4 et le balancier 2, sans modifier la position de la masselotte 4.
    [0021] Une insertion axiale permet une séquence d’assemblage simple, illustrée par les fig. 3 à 5: on équipe tout d’abord une tige à relief 3 (comportant ici, non limitativement, une masselotte 4) d’une rondelle 1, et on assemble ce sous-ensemble avec le balancier.
    [0022] The simplicity of insertion of such a washer which is split radially allows a great flexibility of use. In particular, it is possible to equip the same raised rod 3 with a plurality of washers 1.
    [0023] FIGS. 1 to 13 illustrate a single radial slot which can be delimited by parallel faces as seen in FIGS. 1 and 12, or by lateral surfaces defining a hard point as in FIG. 13. These figures are not limiting, since very varied shapes can be used for such washers.
    [0024] FIG. 15 shows another example with a planar snail washer, which has a point threshold in the free state.
    [0025] FIG. 16 is a left version of a snail washer, comparable to a portion of a helix, which can develop over more than one complete turn as in the example of the figure. The washer 1 is then left and comprises at least one elastic open coil 8 wrapping around the washer axis D and is designed to allow an axial insertion or extraction with respect to the stem axis A Under the action of an axial force with respect to this rod axis A, of the washer 1 with respect to the relief rod 3. More particularly, at least one such open coil 8 comprises a winding aperture 58,
    [0026] FIGS. 14 and 17 illustrate other captive variants, that is to say that their radial extraction is impossible, in which the washer 1 is substantially planar, and in which its skirt 11 comprises a plurality of slots 9 which are substantially radial with respect to the other, The slots 9 are preferably each of a width that is very much smaller than the smallest radial dimension of the relief rod 3, so as to prevent any radial insertion or extraction of the washer 1 with respect to the axis of the washer. Axis rod A under the action of a radial or axial force with respect to this rod axis A. This plurality of slots 9 is then arranged to allow a substantially conical elastic deformation of the skirt 11 under the action of a Axial force with respect to the rod axis A, in order to allow an axial insertion or extraction, with respect to the rod axis A,
    [0027] FIG. 18 is a left-handed, umbrella-like variant of the variant of FIG. 17. Its skirt 11 is substantially symmetrical in revolution with respect to the washer axis D and has a plurality of slots 9 which are substantially radial with respect to the washer axis D and each have a width that is much smaller than the smallest Dimension of the relief rod 3 so as to prevent any radial insertion or extraction of the washer 1 with respect to the rod axis A under the action of a radial or axial force with respect to this axis Of rod A. The plurality of slots 9 is arranged to allow an elastic conical deformation of the skirt 11 under the action of an axial force with respect to the rod axis A, in order to allow an axial introduction or extraction, Relative to this rod axis A,
    In a particular variant (not shown), the washer 1 is left when it is intended to cooperate with a threaded relief rod 3, in a substantially helical profile in the same direction as said threaded relief rod 3, with a different pitch from That of the threaded relief rod 3 concerned, and between 0.80 and 1.20 times the pitch value of this threaded relief rod 3, and preferably between 0.80 and 0.90 times, or between 1 , 10 and 1.20 times this value.
    Advantageously, the axial orifice 10 is delimited laterally by at least two opposite surfaces 12, 13, 14 which, when the washer 1 is designed to cooperate with a threaded relief rod 3, define, in each plane passing through The washer axis D, a profile substantially complementary to that of this threaded relief rod 3, for example an involute profile, or a frustoconical profile, or the like.
    In a particular case, the axial orifice 10 is a bore centered on the washer axis D and is delimited laterally by such opposite surfaces 12, 13, 14 which are perpendicular to the washer axis D, And which are preferably uniformly distributed over the circumference of the orifice 10.
    [0031] Dans une autre variante particulière au moins une de ces surfaces opposées 12,13,14, est agencée pour exercer une friction sur la tige à relief 3, par un état de surface supérieur à 12 micromètres Ra, ou/et par un traitement de surface particulier, notamment dans un cas particulier un revêtement de friction avec un coefficient de friction avec l’acier supérieur à 0,4.
    [0032] On comprend que l’invention est conçue pour affiner le réglage classique d’inertie fait au moyen de masselottes 4, et que les rondelles 1 selon l’invention ont pour fonction de constituer des valeurs en quelque sorte décimales des valeurs d’inertie déterminées par la mise en position des masselottes.
    [0033] Dans un exemple particulier, une rondelle 1, telle que représentée à la fig. 1, avec un diamètre hors tout de 0,60 mm et un diamètre d’orifice de l’ordre de 0,3 mm, une épaisseur de 0,05 mm, une masse de 50 pg environ, réalisée en «Liga-nickel», permet un réglage de 0,9 seconde par tour de rondelle, pour un balancier 2 de forte inertie (environ 20 mg*cm2), ce qui fait de la rondelle 1, facilement réglable au sixième de tour, un système environ trente fois plus sensible que des vis de réglage. Le choix de ce matériau lui permet de tolérer, pour la géométrie de la fig. 1, une expansion diamétrale au moins égale à son épaisseur, et pouvant atteindre une fois et demi son épaisseur, et pouvant notamment atteindre environ 15% de la valeur du diamètre intérieur. L’invention permet donc un réglage à la fois fin, précis, avec une rondelle 1 unique facilement déplaçable, à la fois en translation et en rotation, sur la tige à relief 3, surtout quand celle-ci est une tige filetée.
    The user can nevertheless juxtapose several washers 1 on one and the same relief rod 3. In a particular variant, it can also bring them into contact and drive them one with the other, thus producing a washer composed of mass higher. To this end, and in a variant, the washer 1 comprises, on at least one lateral surface substantially orthogonal to the washer axis D, at least one drive means or a notch arranged to cooperate with a complementary driving means Or a complementary notch, which comprises another adjacent washer 1, for a pivoting stop with respect to the latter.
    [0035] Dans une variante particulière, l’orifice 10 de la rondelle 1 est cranté, ou est cannelé, ou comporte un état de surface supérieur à 12 micromètres Ra, ou comporte un revêtement de friction avec un coefficient de friction avec l’acier supérieur à 0,4.
    In a particular variant, the washer 1 has a mass of less than 50 μg. In combination with a linear travel of a few tenths of a millimeter on the relief rod 3, this value is sufficient for a fine adjustment of the inertia. When the raised rod 3 is a threaded rod, in a preferred case illustrated by the figures, the peripheral profile 6, in star shape or the like, provides high sensitivity and allows true micro-adjustment, since it is thus possible to descend well - below the target of the second per day for the regulation of the walking, with an adjustment step of 0.1 to 0.2 seconds per day approximately.
    In a particular variant, the washer 1a and a specific inertia with respect to the washer axis D of less than 2.5 μg * mm2.
    [0038] Avantageusement, la rondelle 1, qui est de très petites dimensions et doit posséder de bonnes propriétés élastiques en même temps qu’une bonne tenue dans le temps, est en matériau micro-usinable ou en silicium ou oxyde de silicium ou DLC.
    [0039] L’invention concerne encore un balancier d’horlogerie 2 comportant, solidaire de sa serge 20 ou d’une masselotte 4 rapportée sur sa serge 20, au moins une tige à relief 3 s’étendant selon un axe de tige A. plus particulièrement cette tige à relief 3 est filetée ou annelée ou comporte une succession de profils creux 31 séparés par des sommets 32, et s’étend diamétralement entre, d’une part un diamètre minimal DMIN de noyau, et d’autre part un diamètre maximal DMAX de sommet de profil.
    According to the invention, on this balance 2, at least two raised rods 3 are each arranged to receive at least one such washer 1, adapted to its profile and to its minimum diameter DMIN of core and maximum diameter DMAX of vertex Of profile.
    [0041] In a particular variant, at least one relief rod 3 is a helical screw.
    In a particular variant, at least one relief rod 3 is a ring-shaped shaft, as can be seen in FIG. 23.
    The relief rods 3, mounted radially with respect to the axis of the balance, have a double advantage: the rapid passage of a washer 1, acting solely on its elasticity, and without rotating it with respect to Its axis D makes it possible to quickly obtain a half-end adjustment of the step, of the order of a second per day or a few seconds per day depending on the arrangement of the relief rod 3, and the fine adjustment , Of the order of the tenth of a second per day, is realizable by rotating the washer about its axis D which is then substantially coincident with the axis A of the rod 3.
    Of course, other arrangements than a radial arrangement are possible, for example tangential, but are then rather usable for a displacement of the center of inertia of the equipped balancer.
    The pinching characteristics of the elastic washers 1 according to the invention make them also usable for other types of rods, in particular rods having smooth bearing surfaces, here called smooth rods 30.
    The pinching torque of the washers 1 allows them to be held on smooth bearing surfaces, this retention can be improved by surface treatment of the inside of the washer 1, at the orifice 10, in particular a bore, and surfaces
