Definitions

  • the invention relates to a method for producing a tube for a friction system. It also relates to a method of producing friction between a shaft and such a tube. It also relates to a tube for producing such friction. It also relates to an assembly producing such friction. It also relates to a movement comprising such a tube or such an assembly. Finally, it relates to a timepiece, in particular a wristwatch, comprising such a tube or such an assembly or such a movement.
  • the driving of the hands or discs allowing the display of the time on a watch is generally done by means of a roadway, which one comes to pinch then drive out on a tigeron of a center pinion. Pinching creates two bumps in the tube or barrel of the roadway which come into contact with the tigeron and thus ensure, by friction of the bumps on the tigeron, the transmission of the rotation of the center pinion to the roadway in normal operating mode time display.
  • Adjusting the diameter of the tiger and the distance between the bumps ensures the transmission of a torque allowing the rotation of the minute hand.
  • the higher this torque the better the needles will behave at impact.
  • the rotation of the rod causes the rotation of the roadway by means of a correction mechanism, which slides on the center pinion to position the hand in the right place relative to the dial.
  • Such a pavement - center gable structure constitutes, for example, lanterning.
  • Too much friction or friction torque results in a difficult adjustment feeling and also induces wear on the lanterning.
  • the lanterning operation is carried out by a constriction pinch of a tube of the roadway facing a span or a clearance of the tigeron.
  • This pinching is a manual task, and its result depends on the dexterity and sensitivity of the watchmaker, and is therefore random.
  • the purpose of the lanterning is to ensure a certain level of friction between the tigeron and the roadway during normal operation of the watch in order to display the time, while the manual operations of time setting by the user apply a torque greater than that of friction. The friction torque should therefore not be too high.
  • the roadway is adjusted with greasy friction on the shaft of the minute pinion, which generally comprises a groove (“lantern notch”) making it possible to accommodate two bulges generated in the wall of the roadway.
  • a groove (“lantern notch”) making it possible to accommodate two bulges generated in the wall of the roadway.
  • Sufficient quality of such an assembly can only be ensured by pairing the roadway and the center pinion so that the lanterning is perfectly adjusted, on pain of seeing the roadway wobble and the needles move unexpectedly.
  • Document CH129931 presents a solution that has become traditional, consisting in using a pinion with a support cone guaranteeing the centering of the roadway on the center pinion before lanterning.
  • the lanterning of the roadway is therefore a traditional method which requires skill on the part of the watchmaker who must sometimes return to the roadway to adapt it to the gable, or a perfect mastery of the geometries or the couples obtained in the case of more industrial.
  • the pavement is traditionally machined in free-cutting steel (20AP or Finemac) and then hardened by heat treatment according to the supplier's instructions to reach a hardness of 550 ⁇ 50 HV.
  • This hardness corresponds to a compromise to allow both the deformation of the roadway without cracking during the lanterning step, and the maintenance of the torque over time.
  • the material is put in a metallurgical state allowing the lanterning to be corrected by the watchmaker until the correct torque is obtained.
  • This hardening heat treatment has the consequence, in addition to increasing the hardness of the pavement to make it more resistant to wear, to increase the elastic return and reduce the elongation at break. On the other hand, it only modifies the dimensions of the roadway in a negligible way, even on a watchmaking scale.
  • the lanterning step generates a narrowing of the internal diameter of the roadway along an axis located in the plane perpendicular to the axis of the roadway, to bring the distance between bumps to a chosen theoretical value.
  • the parts are then assembled on the movement: the roadway is driven out on the center pinion and the two bumps made during the previous step are slightly elastically spread during insertion on the pinion, then come to be housed in a groove or on a cone made on the pinion, and ensure the relative positioning of the two parts along the axis of the roadway, as well as the relative maintenance of the two parts in rotation until a friction torque defined by the geometry and the rigidity of the parts .
  • This torque is checked or measured and, if it is not sufficient, the roadway is removed and changed, or pinched again.
  • the material characteristics of the two components are respectively a hardness of 550 ⁇ 50 HV for the roadway and 650 ⁇ 50 HV for the pinion, both made of 20AP steel.
  • the document EP2881803 describes a recent alternative to lanterning obtained using a shape memory alloy ring intended to tighten the roadway around the tigeron.
  • the ring is widened at low temperature (martensitic state), placed opposite the pavement area and then heated to reach the austenitic structure allowing its tightening and the controlled maintenance of the pavement on the tigeron.
  • Document CH41140 presents a longitudinally split barrel carriageway making it easier to insert the carriageway on the center pinion.
  • a circular rim created on the lower part of the roadway is inserted into a groove located between spans of the center pinion.
  • the control of the lanterning torque cannot be industrialized with the known methods without resorting to pairings, because the torque very precisely depends on the internal diameters of the roadway and the external pinion of the center gear.
  • the machining tolerances and the additional dispersion induced by the heat treatment then the nipping are such that it is necessary to pair lots to guarantee a friction torque within the required tolerances.
  • the standard deviation of the couples measured on sets of at least 500 tubes assembled on 500 shafts is of the order of 0.3 to 0.35 mNm.
  • the object of the invention is to provide a lantern friction device which makes it possible to remedy the drawbacks mentioned above and to improve the devices known from the prior art.
  • the invention provides a simple, reliable and reproducible friction device and a method for producing such a device.
  • a method according to the invention is defined by claim 1.
  • a tube according to the invention is defined by claim 8.
  • a set of tubes according to the invention is defined by claim 9.
  • a watch movement according to the invention is defined by claim 13.
  • a timepiece according to the invention is defined by claim 14.
  • the appended figure shows by way of example an embodiment of a timepiece.
  • the figure 1 is a diagram of an embodiment of a timepiece.
  • the timepiece is for example a watch or a wristwatch.
  • the timepiece may include a timepiece movement 100, in particular a mechanical timepiece movement, in particular automatic, or electronic timepiece.
  • the timepiece may also include a timepiece assembly, in particular a watch case intended to contain the movement.
  • the movement comprises an assembly 3 or a friction system 3 comprising a shaft 2 and a tube 1.
  • the shaft is housed in the tube 1.
  • the tube 1 is a carriageway or a carriageway and the shaft 2 is a center gear, in particular a shafted center gear.
  • the shaft 2 and the tube 1 each have diameters D which are equal to the ready functional clearance which allow the tube 1 to slide freely relative to the shaft 2 along an axis A and which allow the tube to rotate freely relatively to the shaft 2 around the axis A.
  • the diameters D are for example between 0.3 mm and 2 mm, or even between 0.6 mm and 1 mm.
  • the diameters D are less than or equal to 2 mm, or even less than or equal to 1 mm.
  • the assembly comprises a lanterning, that is to say that the shaft 2 and / or the tube further comprise particular conformations 11, 21 in order to produce friction between the tube and the shaft 2.
  • the shaft 2 comprises a groove or a conical clearance 21.
  • the tube comprises at least one boss 11 or at least one boss, preferably two, three or four bosses produced in the same plane P perpendicular to the axis A or at least substantially in the same plane P perpendicular to the axis A.
  • the boss or bosses are made in a portion 12 of lesser thickness of the roadway.
  • the groove or the conical clearance on the one hand, and the bump (s) on the other hand are arranged to cooperate by contact with each other when the shaft 2 is positioned in the tube 1, in particular when the tube is driven into the shaft 2 until a shoulder 22 formed on the shaft 2 comes into contact against an abutment surface 13 of the tube.
  • the bump (s) are in contact with a portion or a circle of the groove or the clearance having a diameter d1.
  • the distance d2 (not shown) between bumps or the diameter d2 of the circle inscribed in the right cross section of the tube at the tops of the bumps or in the vicinity of the tops of the bumps is less than the diameter d1.
  • the tube 1 is elastically deformed at the level of the bumps, so that the distance between bumps or the diameter of the circle inscribed in the right cross section of the tube at the tops of the bumps or near the peaks of the bumps is d1. It follows that the tube 1 exerts on the shaft 2 radial or substantially radial forces. Combined with shaft-tube friction, these forces define a shaft-tube friction couple.
  • the torque mainly depends on the stiffness of the bumps and / or the elastic deformation of the bumps and / or the coefficient of friction at the shaft-tube interface.
  • the friction torque between the shaft 2 and the tube 1 is greater than or equal to 1.8 mNm, or even greater than or equal to 2.0 mNm.
  • the tube 1 can be a roadway tube.
  • a needle can be fixed on such a tube.
  • a needle can be in kinematic connection with such a tube.
  • the assembly can be used for the correction of one or more hands for indicating watch information.
  • the assembly can be used to correct any type of organ for indicating watchmaking information or derived from the time, in particular to correct a disc.
  • the assembly can be a clutch or a torque limiter.
  • the shaft 2 can be axially movable relative to the tube 1 between a position such as that shown on the figure 1 (engaged position) and a position in which the bumps are opposite a deeper groove in the shaft 2 in which they do not rub (disengaged position in which the tube 1 rotates freely around the shaft).
  • the tube 1 is made of 20AP alloy or of Finemac alloy.
  • the tube 1 can be made of stainless steel.
  • the tube 1 can be made of a beryllium copper alloy such as CuBe2.
  • the shaft 2 is made of 20AP alloy or of Finemac alloy.
  • Embodiments of a method for producing the tube 1 for a friction system comprising the tube 1 and the shaft 2 are described below.
  • the method for producing the tube 1 comprises a step of plastic deformation of the tube 1, in particular a step of plastic deformation of the tube 1 controlled in deformation, the deformation step being carried out on a portion of the tube in the annealed condition and / or whose elastic limit is less than 1000 MPa and / or whose hardness is less than 400 HV or less than 350 HV.
  • the heat treatment applied has almost no influence on the dimensions of the part, whereas it induces a modification of the response of the part to mechanical stresses.
  • the response to torque is thus more homogeneous on parts pinched in the annealed state or in the delivery state than on parts previously hardened and then pinched.
  • the realization of the controlled pinching in dimension improves the dimensional regularity of the inter-bosses.
  • the dispersion induced by the pinching of the uncured material is less than on the cured material. Consequently, pinching has a more homogeneous and repeatable behavior than on hardened material thermally, and the dispersion of the final dimensions of the tube 1, in particular of the dimension between bosses d2, linked to the process, is much lower.
  • a material is more ductile and less subject to variations than thermally hardened material.
  • the plastic deformation step is for example carried out on the material as delivered, slightly hardened or in the annealed state. It makes it possible to obtain plastic deformations of greater amplitude, which then makes it possible to obtain greater friction torques, for example beyond 1.6 mNm. Associated with the pinch control in size and no longer in force, this solution also makes it possible to reduce the dispersion within batches of roadways and to avoid pairing of tubes 1 and trees 2.
  • the step of plastic deformation of the tube 1 comprises the production of at least one bump in the tube. This deformation is preferably carried out by pinching.
  • the tube hardening step may include a quenching treatment followed by a stress relief annealing and if necessary an tempering treatment, or a treatment of structural hardening annealing.
  • the plastic deformation of the tube 1 to form the bumps is carried out not by controlling the force of a clamp pressing on the tube, but by controlling and / or measuring the displacement of the material inside the tube 1.
  • the pinching of the tube is carried out on the hardened material (for example Rp0.2 [20AP]> 1800 MPa and Rp0.2 [Finemac]> 1600 MPa after curing heat treatment).
  • the hardened material for example Rp0.2 [20AP]> 1800 MPa and Rp0.2 [Finemac]> 1600 MPa after curing heat treatment.
  • the deformation step is for example carried out by pinching the tube 1.
  • the deformation step is for example carried out on a portion 12 of the tube whose elongation at break is greater than or equal to 2%, or even greater than or equal to 5%.
  • the deformation step can be controlled by optical measurement of the deformation.
  • the deformation step can be controlled by a template placed in the tube during the deformation step or by passing gauges. In such a case, during the action of the clamp, the tube is deformed until the bumps formed in the tube come into contact with the template.
  • the template is chosen with a diameter smaller than the diameter d2, so that after the elastic withdrawal of the material at the end of the deformation action, the distance between the bumps or the diameter of the circle inscribed in the right cross section of the tube at the tops of the bumps or near the peaks of the bumps is worth d2.
  • An embodiment of a tube according to the invention is obtained by implementing the method described above.
  • All the tubes 1 of a batch delivered in the annealed condition can be deformed repeatedly.
  • this heat treatment applied after plastic deformation has a small influence on the dimensions of the tube 1, and the tolerances are thereby tightened. It is therefore possible, according to the methods described, to obtain a set of at least 500 tubes of which the standard deviation of the diameters of the circles centered on the axes A and inscribed in the straight sections of the tubes at the tops of the bumps is less at 0.2 ⁇ m for a nominal value of 0.758 mm.
  • An embodiment of a method of producing a friction between the shaft 2 and the tube 1 comprises a phase of implementation of the method of producing a tube 1 described above and a step of placing shaft 2 in tube 1.
  • the change in range compared to the prior art has revealed a surprising behavior of the material in that the response to pinching is more homogeneous on a work hardened material than on a hardened material and in that the hardening heat treatment does not influence the dimensions of the part.
  • the change of range thus makes it possible to increase the deformation of the tube and to generate, with equal initial dimensions, larger and more homogeneous bumps which will induce a greater final torque. This therefore ensures a sufficiently high torque between the tube and the shaft, capable of subsequently supporting heavier needles.
  • the retouch rate is significantly lower.
