Definitions

  • the present invention relates to the field of watchmaking. It relates more particularly to a regulating member for a timepiece.
  • a horological regulating member typically comprises a flywheel mounted on an axis, this flywheel being for example a balance or some other form of oscillating mass.
  • a spiral spring is also fixed to the same axis, typically by means of a ferrule integral with the spring or which is integral with its inner end.
  • the integration of the ferrule with the axis is usually carried out by driving the axis into a receiving zone which the ferrule comprises, said zone being conformed to this aim. This driving-in deforms the material of the ferrule elastically and the stresses thus generated serve to tighten the axis.
  • the two elements are thus made integral with one another.
  • the component material typically undergoes a slight plastic deformation in addition.
  • a split ring ferrule may be cited as a traditional example of a ferrule serving this purpose.
  • This method of attachment is ideally suited for metal or polymer components which are relatively elastic and can undergo plastic deformation without breaking.
  • brittle materials have become common in watchmaking. These materials have little or no plastic domain and are therefore extremely fragile. As such, mention may be made of hard steels, ceramics, glasses, glass-ceramics, mono- or polycrystalline silicon, amorphous silicon, oxides, nitrides or silicon carbides under any crystalline regime, alumina, synthetic diamond. and the like.
  • this ferrule of the prior art requires an experienced watchmaker to adjust the angular relationship of the ferrule with respect to the axis in order to ensure the correct indexing of the ferrule with respect to the plate of the balance.
  • a bad adjustment of this angular relationship is harmful for walking and for the isochronism of the regulating organ and should be avoided.
  • using an experienced watchmaker to perform this task is inefficient for production and uneconomical.
  • the document JP 2014/190816 describes a ferrule comprising an opening adapted to receive a non-circular section of the axis of the pendulum. Immediately adjacent to the protruding part of this axis are blades delimited by slots made in the body of the ferrule. These slats form embedded beams at each of its respective ends.
  • the document specifies that there is a space, and therefore a clearance, between the non-circular part of the axis and the ferrule. The presence of these blades seems to be for the purpose of damping shocks, but this document is not entirely clear on this point.
  • the aim of the invention is therefore to provide a watch component in which the aforementioned defects are at least partially overcome.
  • the invention relates to a regulating member for a clockwork movement.
  • This regulating member comprises a flywheel such as a balance wheel, integral in rotation with an axis extending in an axial direction as well as a spiral spring attached to said axis by means of a ferrule integral with 'one end of said spring.
  • the ferrule can thus be fixed to the end of the spring or integrally formed with the latter.
  • the ferrule comprises a receiving area arranged to receive said axis, this receiving area being delimited at least partially by a positioning surface as well as at least two retaining surfaces, at least one of which is movable against a restoring force, provided, for example, by an elastic arm having a free end, or the like.
  • These retaining surfaces are arranged to clamp said axis against said positioning surface in order to make the ferrule and the axis integral with one another. It should be noted that the clamping thus defined involves direct contact between the holding surfaces and the positioning surface, without the interposition of other elements. In doing so, the manufacture tolerances can be very tight since there are only two elements involved, which maximizes the manufacturing precision as well as the relative positioning of the two elements.
  • the axis has a section of non-circular cross section, said holding surfaces as well as said positioning surface cooperating with said section in order to tighten the latter.
  • the section is thus the part of the axis which interacts with the shell in order to make these two elements integral with one another.
  • This section of non-circular section (considered at a non-zero angle to said axial direction) can occupy part or even the whole of the length of the axis, and provides a reference making it possible to index the shell automatically with respect to the 'axis. Any subsequent step of manual adjustment of the angular orientation of the ferrule relative to the axis is thus made superfluous, which simplifies manufacture and thus reduces the associated costs.
  • other non-circular shapes angular, curved, polygonal, oval, irregular and any combination thereof
  • said reception zone comprises a first sub-zone shaped so as to allow the insertion of said axis in said axial direction as well as a second sub-zone adjacent to and in communication with said first sub-area, said second sub-area being arranged to clamp said section, said holding surfaces and said section being arranged so as to allow said axis to be displaced laterally (i.e. at a non-zero angle , in particular perpendicular to said axial direction) in translation from said first sub-zone in order to bring it into said second sub-zone and to be clamped therein.
  • the pin can thus be inserted without (or with little) contact with the ferrule and is secured to the section by means of clipping in the second sub-zone. This arrangement results in less wear of these components during assembly compared to a conventional drive-in.
  • said section and said receiving zone are shaped so as to allow the insertion of the axis in said axial direction when said axis and said ferrule have a first relative angular orientation, and to be tightened.
  • said section against said positioning surface when said ferrule and said axis have a second relative angular orientation distinct from said first orientation.
  • the section comprises at least one flat which cooperates with one of said surfaces, preferably with said positioning surface.
  • a flat is easier to manufacture than other more complex non-circular shapes, and thus provides a simple solution for the automatic indexing of the ferrule relative to the section.
  • At least one, preferably each, of said holding surfaces is carried by an elastic arm which said ferrule comprises.
  • at least some (ideally all) of the elastic arms each have a free end, and are therefore linked to the ferrule at only one of its respective ends.
  • said holding surfaces are each carried by a finger, the fingers extending towards each other from respective ends of each of said elastic arms.
  • At least one of said elastic arms can be folded inwards, which gives them increased elasticity and allows the ferrule to act as a shock absorber to absorb shocks in certain directions.
  • the ferrule is integral with said spring.
  • the ferrule-spring assembly is thus optimized for a one-piece manufacture by the micromechanical machining processes commonly used.
  • the first sub-zone is shaped such that said axis can take place inside this sub-zone without causing movement of said holding surfaces. Any risk of wear when inserting the axis into the reception area is thus avoided.
  • said first sub-zone is defined by said support surfaces as well as two horn-shaped bodies extending preferably symmetrically from the support surfaces.
  • the axis carries a locking element arranged to pass through said reception zone when said axis and said ferrule are oriented according to said first relative angular orientation as well as to block said ferrule axially on said axis when said axis and said ferrule are oriented according to said second relative angular orientation.
  • Axial locking of the ferrule on the axis in the direction limited by said lug is thus ensured, regardless of the shape and length of the section.
  • This locking element advantageously has at least one lug arranged to block said ferrule axially on said axis when the axis and the component are oriented according to said second relative angular orientation.
  • a substantially polygonal shape the vertices of which constitute said lugs is particularly suited to this function.
  • said section has a height parallel to said axial direction which is between 100% and 120%, preferably between 101% and 115%, of the thickness of said shell considered in the same direction. If the section is machined in a cylindrical portion of the axis, the edges of the section can act as shoulders to position the component along the axis.
  • the regulating member further comprises a balance plate mounted on said axis, said plate being indexed relative to said axis by means of an additional section of non-circular shape which said axis comprises.
  • the indexing of the entire regulating member can thus be ensured without subsequent adjustment by an experienced watchmaker.
  • the invention also relates to a timepiece comprising a regulating member according to one of the preceding claims.
  • the figure 1 shows an example of a part of a regulating member 1 not forming part of the invention, seen in partial section.
  • the regulating member 1 comprises a flywheel such as a balance (not shown in order not to overload the figures) mounted integral in rotation with an axis 3 extending in an axial direction Z, of which only the section 5 which cooperates with a ferrule 7 integral with a spiral spring 9 is shown here.
  • the section can be machined in the body of the axis 3, or can extend all along the latter according to the wishes of the manufacturer. Furthermore, only the root 9a of the spiral spring 9 has been shown here, the rest of the latter taking any known shape.
  • the ferrule 7 comprises a hollow receiving area 11 arranged to receive and clamp the section 5 of the axis 3.
  • This area 11 is at least partially delimited on the one hand, by a positioning surface 13, on the other hand, by at least two retaining surfaces 15 which are subjected to an elastic restoring force.
  • the positioning surface 13 is formed on a part of the ferrule 7 which is adjacent to said root 9a, which may be hollow or solid.
  • the retaining surfaces 15 are carried by resilient arms 17 which extend from the root 9a of the spring 9, and the positioning surface 13 is substantially rigid. In other words, the positioning surface is substantially displaceable with respect to the root of the hairspring.
  • the elastic arms 17 are folded inwards in order to give them increased elasticity, and can thus admit certain shocks in the plane of the ferrule 7 in a direction other than towards the positioning surface 13. This s' also applies to the embodiments of figures 4a, 4b and 5 described below.
  • the ferrule 7 is thus formed by at least the root 9a of the spring 9 and the elastic arms 17 and is advantageously integral with the spring 9.
  • the section 5 of the axis 3 has a shape designed to be clamped by the holding surfaces 15 against the positioning surface 13 following an elastic driving of the ferrule 7 on the axis 3.
  • This section 5 is also arranged for s 'index angularly with respect to the positioning surface 13. To do this, it has a shape complementary to that of the positioning surface 13, these complementary shapes ensuring the indexing of the section 5 relative to the ferrule 7.
  • the section 5 comprises at least one flat 19 intended to be in contact with said surface 13.
  • other non-circular shapes are possible, such as a lug or a finger which cooperates with a notch of complementary shape constituting the positioning surface 13, irregular shapes or any other shape allowing such indexing. This generally applies to all of the embodiments of the invention.
  • the rest of the periphery of the section 5 is shaped to cooperate with the retaining surfaces 15 in order to allow the ferrule 7 to be driven out on the axis 3 in a known manner.
  • section 5 and therefore of axis 3 with respect to the ferrule allows the latter to also be indexed with respect to a balance plate (see below) without requiring manual adjustment of the angular relationship of these components.
  • the assembly of the regulating organ is thus simplified and any subsequent fine-tuning by a qualified watchmaker is avoided.
  • the figure 2 illustrates an embodiment of a regulating member 1 according to the invention, which has the same advantages as the example of figure 1 .
  • the reception zone 11 is shaped so as to allow the section 5 to be clipped in a direction perpendicular to said axial direction Z, that is to say in the plane of the shell 7.
  • the receiving zone 11 of the ferrule 7 is defined by the distal parts 17a of the elastic arms 17 which extend from the root 9a of the spring 9 and are divided into two sub-zones.
  • the first sub-zone 11a is the furthest from the root 9a of the spiral spring 9 and is shaped to allow the insertion without driving out of the axis 3 and of its section 5 in said axial direction Z. For this purpose, it is delimited by horn-shaped bodies extending symmetrically from the support surfaces 15, this symmetry not being compulsory.

  • the latter is at least partially delimited by the holding surfaces 15, which are formed as jaws extending towards each other from the distal parts 17a of the elastic arms 17 as well as by the holding surfaces 13.
  • the positioning surfaces 13 are carried by tabs 17b extending from the distal parts 17a of the elastic arms in the direction of the root 9a of the spring 9, and which are bent to form stops for the flat 19 of the section. It goes without saying that other forms of positioning surface are also possible, more or less rigid, which extend from the root 9a or from the elastic arms 17, according to the wishes of the manufacturer. Furthermore, it is also possible to provide only one support surface 13, having an ad hoc shape.
  • the arrangement of positioning 13 and holding 15 surfaces as well as the resilient arms 17 are configured such that when the axis 3 is inserted into the first sub-area 11a and is moved in translation towards the root 9a , the shape of the section causes the retaining surfaces 15 to move apart and bends the elastic arms 17.
  • the section 5 can thus enter the second sub-zone 11b.
  • the elastic arms remain flexed in order to provide a clamping force which tends to clamp the section 5 against the positioning surfaces 13. It is emphasized here that this clamping is by definition direct, without the interposition of other elements whose presence would prevent the two surfaces from positioning themselves. 'against each other. Manufacture tolerances can therefore be reduced to a minimum value.

  • the distal ends of the elastic arms 17 are free, in order to provide sufficient elasticity to the latter.
  • the pin 3 can be inserted into the first area 11a with play (or with slight contact with the elastic arms 17). Then, by moving the axis towards the positioning surface 13, the shape of the section 5 spreads the ends of the elastic arms and bends the arms 17 (see figure 3b ). A stop surface 21 having a shape complementary to that of the positioning surface 13 abuts against the latter when the section 5 is located in the second sub-zone 11b.
  • the ends of the elastic arms 17 are fingers which constitute the holding surfaces 15 and act on the flats 19 in order to position the section 5 angularly and to clamp the latter against the positioning surface 13.
