Definitions

  • the invention relates to a split ferrule whose contour of the central opening intended to receive a pendulum axis is non-circular.
  • the invention also relates to a spiral ring-spring assembly and to a method of mounting a timepiece.
  • Swiss patent no. CH 468662 described, in particular in connection with its figure 3 , a ferrule having four arms, a circular central opening, an elasticity slot for hunting on the axis of a pendulum and a recess for balancing.
  • French patent application number FR 2 124 243 (( US 3,785,028 ) relates to circular sleeves for spiral spring intended to be expelled on the axis of the balance of a watch. These sleeves are made from profiles having an arm for fixing a hairspring and a regulation slot diametrically opposite this arm.
  • ferrules or ferrule-hairspring assemblies made of a material such as silicon, quartz or diamond.
  • these materials which can be machined by techniques such as deep etching (DRIE), do not have a plastic deformation domain, which makes them brittle as soon as the stresses in the material exceed the elastic limit.
  • DRIE deep etching
  • Swiss patent no. 508,233 offers a split ferrule whose circular central opening has a second elasticity slot of small dimension.
  • the two halves of this shell are extremely massive, which makes them very rigid and limits their amplitude of elastic deformation. This makes the shell very fragile, in particular when it is made of a material such as silicon.
  • Swiss patent no. CH 252 387 relates to a ferrule made up of two parts, a hollowed out ring and an elastic U-shaped part arranged transversely inside the hollowed out ring.
  • the two arms of the U are constrained by the hollowed out ring and must be deformed so as to pinch the hairspring blade and accommodate the pendulum axis during hunting.
  • the elasticity to level of the connection of the arms of the U-shaped part is insufficient, which easily leads to the rupture of this part, in particular when it is made of a material such as Silicon.
  • EP 2 112 565 reveals micromechanical parts having a central opening whose contour is not circular but has a rotation symmetry of 2 ⁇ / 3 around the axis passing through the center C of the central opening.
  • a micromechanical part provided with elastic arms.
  • the main object of the invention is to provide a ferrule which can be driven out on axes of different diameters while guaranteeing an adequate rotational holding torque without going beyond the elastic limit of the material and which does not cause unbalance .
  • split ferrules have been around for a very long time, there has never been proposed, until now, a split ferrule having a central opening which is not circular and whose elasticity properties allow the above-mentioned purpose to be achieved, in particular for a material without plastic deformation domain such as silicon, quartz or diamond.
  • this ferrule In addition to its original shape, it has been found that this ferrule is entirely satisfactory, in the sense that it can accommodate axes of different diameters, which it presents, once mounted for example on a pendulum axis, an excellent torque of held on this axis and that its breakage rate during hunting for assembly to an axis is practically zero.
  • Point 21 below provides additional and advantageous characteristics of the coil-spring assembly according to the invention: 21.- Ferrule-spiral spring assembly according to point 20, the ferrule and the spiral spring being in one piece.
  • the invention also relates to a method for mounting a timepiece, comprising driving out a ferrule-spiral spring assembly according to the invention on a pendulum axis.
  • a ferrule is defined by claim 1.
  • a timepiece is defined by claim 15.
  • the split ferrule according to the invention is shown in the figure 1 .
  • it has a slot 1 and a central opening 2 which is intended to receive a pendulum axis.
  • the contour 3 of the central opening 2 is not circular but preferably has a certain symmetry.
  • the shape of the contour 3 of the central opening 2 is then preferably chosen such that this contour 3 has a symmetry of reflection with respect to the line R.
  • this symmetry is orthogonal.
  • the shape of the contour 19 of the shell can be chosen so that this contour 19 also has a symmetry of reflection, preferably orthogonal, with respect to the line R.
  • the aforementioned symmetry of the contour 3 has the advantage of making it possible to avoid an imbalance and to obtain a balanced ferrule.
  • contours 3 or 19 there is not necessarily symmetry of the contours 3 or 19 with respect to the line R.
  • a non-symmetrical contour 3 the asymmetry of which would for example be compensated for by a lug located in the same place as the lug 17 of the figures 3 and 6 to 11 .
  • the center B of the central opening 2 can be distinct from the center C of the contour 19 of the shell, as shown on the figure 1 .
  • the contour 3 of the central opening 2 comprises a first support part 4 and a second support part 5.
  • These support parts 4,5 intended to cooperate with the axis of a pendulum, are preferably symmetrical to each other with respect to slot 1.
  • these parts 4,5 are rectilinear, that is to say that their radius of curvature on the side of the central opening 2 is infinite.
  • the support parts 4,5 can start from points located at the edge of the slot 1.
  • the arm 6 carries, on its side facing the center B, the first straight support part 4 of the outline of the opening.
  • the arm 7 carries the second straight support part 5.
  • the role of the arms 6,7 is on the one hand to constitute the points of support of the ferrule on the pendulum axis.
  • the presence of recesses 23,24 between the arms and the neighboring part of the ferrule makes it possible to maximize the length of the elastic zone of the ferrule, which then extends to the slot and covers an arc almost 180 ° on each half. Without the arms 6,7 and the recesses 23,24, the length of the elastic parts would be much lower and the stress level would be higher for an equivalent tightening at the level of the axis. In addition, the stresses can be distributed over a greater distance. We therefore see that the presence of arms 6,7 defined by the recesses 23,24 between the arms 6,7 and the neighboring part of the shell gives the latter great robustness.
  • the arms 6,7 are generally not considered to be elastic arms because, when hunting of the ferrule on the pendulum axis, in principle, they do not deform elastically.
  • the slot of the ferrule defines two halves of ferrule 21, 22 on either side of the straight line R, indicated by dashed lines on the figure 2 . It is the shapes of these two halves 21, 22 which give the shell its elasticity. This fact is confirmed by simulations of hunting the shell of the figure 2 which show that there is no elastic deformation of the arms 6,7 following the driving out of an axis.
  • the length and the shape of the arms 6,7 which are defined by the recesses 23,24 situated between the arms 6,7 and the ferrule, on the side opposite to the center B, are second order parameters.
  • the shape of the shell halves 21,22 is important and is chosen so as to distribute the elastic stresses in the most balanced way possible along the contour of the shell and on the two shell halves 21,22, all by guaranteeing both sufficient elasticity to allow the driving of pendulum axes whose diameter is included in the desired tolerance range and a stress level which always remains clearly below the elastic limit of the material. This choice can be made, for example, following an optimization of the shape of the shell halves 21, 22 using a digital simulation program implementing the finite element method, such as ANSYS.
  • the presence of the arms 6,7 makes it possible to bring the corresponding support point (s) closer to the center of the shell, without thickening the shell halves 21,22, therefore without the stiffen. This therefore makes it possible to optimize the placement of the support points and the elastic deformation properties of the ferrule separately (amplitude of deformation, distribution of stresses, etc.).
  • each arm 6.7 opposite the center B can also be straight.
  • each arm 6,7 is preferably provided at its free end and on the side opposite to the center B, with a bulge 10,11. This bulge makes it possible to further optimize the balancing by adding material but it does not serve as a fulcrum or abutment.
  • the support parts can be concave, that is to say that the radius of curvature of the support parts can be positive on the side of the central opening 2.
  • the central opening 2 is intended to receive a pendulum axis which generally has a circular cross section. Depending on the shape of the central opening 2, there may therefore be more or less contact points 29 between the balance axle and the split ferrule.
  • the contour 3 of the central opening 2 may include a third support portion 12 situated opposite the slot 1.
  • the tangent at the point 29 closest to the center B of the contour 3 of the central opening 2 is substantially perpendicular to the straight line R (or to the slot 1). This point 29 is the point of contact provided with the pendulum axis.
  • the support part 12 is rectilinear, but it could also be convex or concave.
  • the pendulum axis comes into contact with the central opening 2 at three places 29: on each of the first and second parts of straight support 4.5 of the arms 6.7 and on the third support part 12, just opposite the slot 1, at the point of intersection with the line R.
  • the centers of the contours will move very slightly following the driving out of the pendulum axis .
  • the outline of the opening 2 comprises a fourth support part 14 and a fifth support part 15.
  • These support parts 14, 15 are symmetrical with one another with respect to the slot 1 and they meet at a point 16 preferably located opposite the slot 1.
  • This configuration makes it possible to obtain four contact points 29 between the pendulum axis and the central opening 2: two contact points on the first and second support parts 4,5, which are convex in this example, and two other contact points on the fourth and fifth support parts 14,15, which are rectilinear in this example.
  • the support parts 4,5 have, on the side of the central opening 2, a negative radius of curvature while the support parts 14,15 have an infinite radius of curvature.
  • each half of the shell 21, 22 has been maximized by defining recesses 25, 26 and arms 27, 28 carrying the bearing parts 14, 15.
  • the shape of the shell halves 21, 22 is chosen so as to distribute the elastic stresses homogeneously along the contour of the shell.
  • FIG 5 On the figure 5 is shown a split ferrule with arms 6,7 and 27,28 carrying support parts 4,5 and 14,15 rectilinear, as on the figure 2 , but whose contour 3 of the central opening 2 provides four points of contact with the balance axis.
  • FIG. 6 On the figure 6 a split ferrule with arms 6,7 and 27,28 is shown, but the outline 3 of the central opening 2 of which defines four points of contact with the periphery of the pendulum axis.
  • the bearing parts 4,5 and 14,15 are in this example all convex, that is to say that their radius of curvature on the side of the center B of the central opening 2 is negative.
  • the tangents at the contact points provided between the parts 4,5 and the balance axis and / or between the parts 14,15 and the balance axis can form an angle between them greater than or equal to 60 degrees, even obtuse, on the center side of the central opening 2.
  • the contour 19 of the ferrule according to the invention is generally substantially circular. “Substantially” means here that it is not 100% due to the existence of slot 1 and, if applicable, as can be seen in the figures 3 and 6 , due to the presence, at a point located near the point diametrically opposite to the slot 1, of a lug 17.
  • the latter is preferably located upstream of the point of attachment or departure of the spiral spring (if the we refer to the direction of movement of the hairspring from the inside to the outside).
  • the contour 19 can also be non-circular, even asymmetrical. It could thus protect the turns in the event of an impact.
  • the split ferrule according to the invention is, by definition, intended to support a spiral spring. The beginning of it is visible on the figures 3 and 6 , where it has the reference number 18.
  • This spiral spring 18 is preferably connected to the ferrule at a point located on the contour 19 thereof, substantially opposite the slot 1. This makes it possible to minimize the displacement of the spiral spring during mounting of the ferrule on an axis balance and avoid affecting the chronometric properties.
  • the example of the figure 2 where one of the contact points 29 is located on or near the straight line R, facing the slot 1, is particularly favorable.
  • the spiral spring can be a part fixed to the ferrule, but, preferably, it forms only one part with it.
  • balancing holes 20 are provided in a part of the shell opposite to the slot 1, if necessary, even in the lug 17, as can be seen in the variants represented on the figures 7 to 10 .
  • the point A representing the longitudinal axis of symmetry of the balance, the center B of the contour 3 of the central opening 2 of the shell and the geometric center C of the contour 19 of the shell can all be distinct.
  • the split ferrule according to the invention is dimensioned both to maintain the spiral spring 18 on the pendulum axis during the operation of the oscillator (minimum tightening torque) and also to be able to be assembled with axes whose diameters have fluctuations and this, without breaking or undergoing plastic deformation if the diameter of the pendulum axis remains within a tolerance interval given.
  • This point is particularly important if the shell is made of a material such as silicon which does not have a plastic deformation domain, since the risk of breakage or cracking is significant if the stress exceeds the limit of elastic deformation.
  • the support parts 4,5 and / or 14,15 and / or 12 can be rectilinear ( Fig. 1.2 , 5 , 7.8 , 9.10 and 13 ), that is to say that they can have an infinite radius of curvature, convex, that is to say with a negative radius of curvature on the side of the central opening 2 (cf. parts 4,5 of the Fig. 4 , Fig. 6 , Fig. 11 ), or concaves ( Fig. 3 ), i.e. with a positive radius of curvature.
  • the positive radius of curvature is greater than 0.62 times the diameter d max of the largest circle that can be drawn inside the contour of the central opening, a circle which is also called “Inscribed circle” in the following description.
  • This circle corresponds approximately to circle 13 of center A visible on the figures 2 and 4 , with the difference that the inscribed circle has a slightly smaller diameter than that of the pendulum axis.
  • a positive radius of curvature greater than 0.62 times the diameter d max of the inscribed circle makes it possible to define a single point of contact between the bearing part and the balance axis: in the case of the figure 3 , a radius of curvature greater than 0.62 times the diameter d max of the inscribed circle results in a space of approximately 5 microns at the ends of the arms if the contact point is placed in the center of the arms, which is suitable for defining a single point-of-contact. Similarly, a radius of curvature greater than the diameter d max of the inscribed circle results in a space of 10 microns at the ends of the arms. A radius of curvature greater than 0.75 times the diameter d max of the inscribed circle is also an appropriate value.
  • the tangents to the support points 4,5 and / or 14,15 at the points of contact provided with the pendulum axis form between them, on the side of the center B of the central opening 2, an angle preferably greater than or equal to 60 degrees. Even more preferably, it is an obtuse angle.
  • the support parts 4,5 and / or 14,15 and / or 12 are configured so as to each define a precise point of contact 29 with the axis of the pendulum.
  • the fact of being able to define the configuration and the number of support points makes it possible to best balance the forces which act on the pendulum axis. This is not the case with a ferrule according to the prior art, the radius of the internal opening of which is substantially equal to or less than the radius of the pendulum axis, and the support points of which are not defined.
  • the split ferrule according to the invention can be made of any suitable material, such as silicon, quartz, diamond, etc. It can be manufactured using well-known micro-manufacturing techniques, such as the DRIE processes for silicon, quartz or diamond or UV-Liga for Ni or NiP. These techniques have the advantage of making it possible to easily produce very complex shapes or geometries.
  • the shape of the slot 1 is not necessarily elongated.
  • a split ferrule according to the invention is shown, the slot 1 of which has rounded ends.
  • the arms 6,7 carry convex support parts and that the third support part 12 is also convex.
  • a ferrule is represented, the support points of which form an equilateral triangle and are arranged at 120 ° from each other, thus allowing a balance of forces at the level of the tightening of the axis.
  • each support part is provided to define a single point of contact with the pendulum axis.
  • the support parts can show different radii of curvature between them. In addition, it is also possible to vary the radius of curvature along the same support part.
  • each half of ferrule 21, 22 has the advantageous characteristic of deforming elastically, that is to say without plastic deformation or risk of breakage.
  • the figure 12 is a graph representing the evolution of the holding torque M of the ferrule as a function of the diameter D of the axis of a pendulum, for split ferrules according to the invention and non-split ferrules according to the prior art, namely , the aforementioned European patent application no. EP 2 112 565 .
  • the parts were all made of silicon using the DRIE process.
  • the pendulum axes used had a diameter between 0.495 and 0.512 mm.
  • the desired tolerance interval is in this case between 0.500 and 0.506 mm.
  • the diameter of the inscribed circle d max was 0.485 mm.
  • the holding torque is greater than the minimum torque required, even for small diameters below the minimum tolerance, and the dependence on the diameter is much less (slope lower by a factor of three and six , respectively, to those of the ferrules of the prior art).
