Definitions

  • the present invention relates to an exhaust device for a timepiece.
  • the exhaust device constitutes a master piece, being charged on the one hand to deliver the energy necessary for the maintenance of oscillator oscillation movement. mechanical, balance and hairspring, and secondly to transmit the oscillation frequency of the oscillator to the gear train causing the time display.
  • FR-A-1522609 describes an exhaust device that avoids these drawbacks, but is intended for an electric timepiece.
  • An object of the present invention is therefore to provide an exhaust device for an improved timepiece relative to known devices, that is to say whose known disadvantages have been at least partially reduced.
  • Another object of the invention is to provide an exhaust device that is insensitive to external shocks and does not exhibit a galloping phenomenon.
  • Yet another object of the invention is to propose a timepiece provided with such an exhaust device.
  • the figure 1 represents a schematic diagram of a mechanical watch in which the mechanical energy coming from a winding device, manual or automatic, is stored in a mainspring 1 to be distributed through a set of gear wheels 2 to a mechanical mechanism Exhaust 3 and a display 4.
  • the purpose of the exhaust device 3 is, on the one hand, to deliver the energy necessary to maintain the oscillations of the oscillator 5, generally comprising a spiral spring and a mass of inertia, and other part of transmitting the frequency delivered by this oscillator to the gear 2 to synchronize the time display with this frequency.
  • a good exhaust system must not only have a good transmission efficiency between the power source and the oscillator, but it must also preserve the isochronism of the oscillator. For this, the inertias related to the exhaust device must be reduced to a minimum and the energy transfer between the exhaust device and the oscillator must be done over a very short time, while the speed of the oscillator is Max.
  • the figure 2 shows a first embodiment of an exhaust device 3 according to the invention comprising: a transmission wheel 30, driven by the gear assembly 2 seen above, locking means 31, means for producing a magnetic torque 32, intermediate transmission means 33, unlocking means 34 and energy transmission means 35. These various means are described in more detail below.
  • the figure 3 shows the transmission wheel 30 and the locking means 31.
  • the transmission wheel 30 is rotated from the barrel spring 1 via the gear 2, being driven by a mechanical torque substantially constant value.
  • the shaft 300 supporting the transmission wheel 30 transmits the advance movement to the device 4.
  • the locking means 31 are constituted here by a piece of shape or cam 310, mounted on the same shaft 333 as a pinion 330 forming part of the intermediate transmission means shown in more detail in FIG. figure 7 , as well as pins 311 mounted projecting on the transmission wheel 30, perpendicular to the plane of said transmission wheel.
  • the pins 311 are regularly distributed over a perimeter of said transmission wheel.
  • the transmission wheel 30 comprises 10 pins 311, but could include a different number as required.
  • the shape and the dimensions of the cam 310, as well as the diameter of the pins 311 as well as the diameter of the perimeter on which they have been implanted, are determined so that when the cam 310, in simultaneous rotation with the pinion 330 driven by the transmission wheel 30, has one or the other of its lateral faces 312 to the transmission wheel 30, the torque transmission can be done directly from the wheel 30 to the pinion 330.
  • the torque transmission can be done directly from the wheel 30 to the pinion 330.
  • it is a end face 313 which arrives in front of a pin 311 there is a blocking of this end face 313 of the cam 310 on the pin 311, with interruption of the transmitted torque.
  • the figure 4 shows the shape of the mechanical torque transmitted to the shaft 333 carrying the pinion 330 as a function of the angle of rotation of said pinion.
  • the curve first has a constant value torque, until the cam 310 reaches the locking position, marked at A 1 in the figure, where the transmitted torque is canceled.
  • Deblocking means which will be described below then enable the device to be unlocked, thereby allowing the torque of constant value to be transmitted again until the next blocking, marked at A 2 , and so on.
  • the locking means 31 described here cause two locking positions A 1 and A 2 per turn of the pinion 330, but they could equally well be designed to cause a different number.
  • the figure 5 shows a preferred embodiment of means making it possible to obtain a variable torque as a function of the angle of rotation of the pinion 330.
  • these means 32 are of the magnetic type, comprising a stator 320 and a rotor 321 disposed within said stator.
  • the stator 320 consists of a ring of soft ferromagnetic material, having on its inner periphery two cells 322 diametrically opposed.
  • the rotor 321 consists of a permanent magnet of cylindrical shape, having a diametrical magnetization, represented by the arrow in the drawing.
  • the rotor 321 is fixed on the same shaft 333 as the pinion 330 and the cam 310 described above.
  • the presence of the cells 322 creates, during the rotation of the rotor 321, a magnetic torque acting on said rotor, having a substantially sinusoidal appearance as seen in FIG. figure 6 .
  • the rotor 321 is oriented so that its axis of magnetization is parallel to the axis CC of the figure 5 , respectively perpendicular to the axis BB carrying the two cavities 322, the rotor 321 is in stable equilibrium position, a slight angular offset tending to bring the rotor towards this stable position, whereas when the same rotor is oriented from so that its axis of magnetization is parallel to the axis BB, it is in unstable equilibrium position, that is to say that a slight angular offset tends to move the rotor even further from this position unstable.
  • Stable angular positions are marked S on the curve of the figure 6 they correspond to a zero crossing of the curve with a negative slope of the torque curve while the unstable angular positions are marked I on the same curve and correspond to a zero crossing with a positive slope of the torque curve.
  • the frequency of the curve representing the torque is twice that of the rotation of the magnet, respectively of the pinion 330, this being due to the stator / rotor configuration described. Another configuration would have a multiple different from two between these two frequencies.
  • the intermediate transmission means 33 represented in the figure 7 essentially comprise the pinion 330 already seen above and a second transmission wheel 331 mounted on a shaft 339. Recall that the shaft 333 carrying the pinion 330 also carries the cam 310 and the rotor 321.

  • the clearance pallet 340 is integral with the oscillator (not shown in the figure) and oscillates on the shaft 341. During its oscillation movement in the counter-clockwise direction, the tooth of the pallet 340 encounters a tooth of the escape wheel 342, giving it a torque pulse in the clockwise direction.
  • the escape wheel 342 being mounted on the same shaft 339 as the second transmission wheel 331 seen above, this torque pulse is transmitted from this transmission wheel 331 to the pinion 330.
  • the anti-clockwise torque pulse transmitted to the pinion 330 unblocks the cam 310 of its locking position on the pin 311, allowing the wheel of transmission 30 to perform a portion of a turn until the next block.
  • the time display 4 has thus advanced a time portion corresponding to a movement of the pallet 340.
  • the figure 9 shows means 35 for transmitting energy to the oscillator of conventional construction, consisting of a transmission wheel 350 fixed on the same shaft 339 as the wheel 331 and the escape wheel 342, and a piece of form 351, mounted on the shaft 341 seen above and attached to the balance of the spiral (not shown).

  • These two unstable positions I 1 and I 2 are defined as previously by a zero crossing of the torque curve with a positive slope.
  • FIG. 11 there is shown a second way to obtain a variable mechanical torque having two stable points and two unstable points per wheel revolution.
  • a cam 323 is fixed on the same shaft 333 as the pinion 330 seen above; this cam having two concave portions and two convex portions.
  • a spring lever 324, pivoted on one of its ends, is supported by a wheel 325 on the The resulting torque of this device has a variable shape, with two stable points when the wheel 325 is aligned with the axis CC and two unstable points when it is aligned on the axis BB.
  • the figure 10 represents the shape of the mechanical torque acting on the shaft 333 of the pinion 330 in the absence of contact with the oscillator as a function of the angle of rotation of said pinion, we can now describe in parallel the operation of the device in function time.
  • the device After a first rotation, the device arrives in the locked position, as described with reference to the figure 3 , and corresponding to point S 1 of the figure 10 . The device remains in this position for a duration T 1 .
  • the pinion 330 When the pinion 330 receives the unlocking pulse, as described with reference to FIG. figure 8 it moves from the position S 1 to the position I 1 of the figure 10 , this passage taking place during a very short time, called T 2 , less than a thousandth of a second. This duration should be as short as possible so as to disturb the oscillator only minimally.
  • the resulting torque becoming positive provides the oscillator, through the energy transmission means described, the energy required for the oscillator for a duration T 3 of the order of a few thousandths of seconds until the next lock position S 2 .

  • the wheel Exhaust 30 advance one step clockwise each oscillation of the balance.
  • the unlocking means 34 give more than one pulse per oscillation period, which causes a running advance of the watch here called gallop.
