Definitions

  • the invention relates to a timepiece whose chronometric performances are improved and, more specifically, whose mechanical movement is capable of operating at 72,000 vibrations per hour, that is to say at a frequency of 10 Hz.
  • the document EP 2,075,651 proposes to perform a movement at more than 5 Hz by respecting a ratio between the number of teeth of the escape wheel and the frequency equal to 5.
  • the document thus discloses the necessity, for a movement at 10 Hz, to use a exhaust wheel with fifty teeth while maintaining the same diameter.
  • the manufacture of fifty teeth with the same diameter is a great constraint that makes it difficult to implement and focus with conventional wheels.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a timepiece whose exhaust system allows the frequency increase oscillation of the balance by modifying a limited number of parts of the movement and, thus, the chronometric performances of the movement.
  • the invention relates to a timepiece comprising a movement comprising a resonator of the balance-spring type and an escapement system of the Swiss wheel-anchor type, characterized in that the balance oscillates more than 36 '. 000 vibrations per hour and in that the exhaust system is at least partially perforated to reduce its inertia and has an escape wheel less than 25 teeth.
  • a timepiece generally annotated 1. It comprises a housing 3 having a middle 2 closed by a bottom (not shown) and an ice 4 and which is intended to receive a mechanical movement 5 between said bottom and the dial 6 of the timepiece 1. As visible in the figure 1 , the timepiece 1 has several complications.
  • the watch movement 5 is capable of displaying the current time (hour, minute, small second located at 9 o'clock making a turn in 30 seconds and a telltale indicating whether the small second is between 0 and 30 seconds or between 30 and 60 seconds, located at 12 o'clock) but also a date (at 6 o'clock), a time zone (time at 6 o'clock), a 24-hour display of the current time (at 3 o'clock) and a chronograph (Central second realizing the turn of the dial 6 in 30 seconds, central minute realizing the turn of the dial 6 in 60 minutes).
  • the seconds of the chronograph and the current time are displayed by performing a revolution of the dial in 30 seconds to offer in particular a measuring accuracy of the chronograph of a tenth of a second. This precision is made possible thanks to the high frequency of the watch movement 5.
  • the watch movement 5 is capable of withstanding a frequency greater than 5 Hz and, in particular, a frequency of 10 Hz.
  • the movement 5 comprises a system of 7 exhaust whose inertia is attenuated by reducing its mass.
  • the movement 5 comprises a resonator 9 of the balance type 8 - spiral 10 and an exhaust system 7 of the type wheel 11 - Swiss anchor 13.
  • the balance 8 is of variable inertia type, that is to say that the four flyweights 40 visible at the periphery of its serge can be individually displaced to adapt its inertia and finally adjust the movement 5
  • the pendulum 8 may, for example, be made of copper-beryllium alloy.
  • the hairspring 10 is preferably one-piece with its ferrule 41 which is fitted on the balance shaft 12.
  • the outer coil 42 of the spiral 10 is punctured on a fixed part of the movement 5 as, for example, a bridge.
  • the inner coil 43 of the spiral 10 has a Grossmann type curve to compensate for the use of the ferrule 41.
  • the spiral 10 may, for example, be formed from monocrystalline silicon and coated with silicon dioxide.
  • the resonator 9 cooperates with the exhaust system 7 by means of a plate mounted on the balance shaft 12.
  • the exhaust system 7, better visible at the Figures 4 to 6 has a Swiss anchor 13 formed by a main face (visible to the figure 6 ) in projection.
  • the Swiss anchor 13 is mainly formed by a rod 14 connecting the fork 15 and the arms 16, 17.
  • the fork 15 comprises two horns 18, 19 opposite one under which is mounted a dart 20 so to cooperate respectively with a pin fixed on said plate of the balance shaft 12 and the lower part of said plate.
  • the rod 14 receives, between the two arms 16, 17, a rod 21 intended to rotate the anchor 13 between a bridge and the plate of the movement 5. Finally, on each arm 16, 17, is fitted a pallet 22, 23 to come into contact with the escape wheel 11.
  • the pallets 22, 23 may, by way of example, be formed in synthetic ruby.
  • the rod 14 and the arms 16, 17 are perforated to reduce the inertia of the exhaust system 7.
  • the opening of said main face projection (visible at the figure 6 ) makes it possible to obtain a mass per unit area of less than 1 mg.mm -2 and, depending on the material used, a weight per unit area decreased to 0.18 mg.mm -2 .
  • the anchor 13 may, for example, be formed from monocrystalline silicon and coated with silicon dioxide.
  • the inertia of the unsupported anchor 13 can go down to 0.75 mg.mm 2 and up to to 2.85 mg.mm 2 when the anchor 13 is fully equipped, that is to say in particular with pallets 22, 23 in ruby.
  • DLC crystalline diamond-shaped carbon
  • the opening of the rod 14 and the arms 16, 17 form, preferably, a structure of the honeycomb type in order to maintain the mechanical strength of the anchor 13 while significantly decreasing its mass.
  • the exhaust system 7 further comprises an escape wheel 11 also formed by a main face (visible at the figure 5 ) in projection.
  • the wheel 11 is formed in a board 25 on which is a pinion 27 via an axis 24, the axis 24 and the pinion 27 can be shaped.
  • the pinion 27 has 8 symmetrical wings 44 which widen as they approach the board 25 to facilitate the driving of the pinion 27 in the wheel 11.
  • the pinion 27 and the axis 24 can, for example, be formed by a metal or a metal alloy such as steel.
  • the board 25 has a hub 26 connected by five arms 28 to the serge 29 which comprises twenty pulse teeth 30.
  • the number of arms 28 and / or teeth 30 may vary, however, advantageously according to the invention, the watch movement 5 can perfectly function at high frequency, that is to say for example at 10 Hz, with a twenty-tooth exhaust wheel 30.
  • the serge 29 and / or the teeth 30 are pierced in order to reduce the inertia of the exhaust system 7.
  • the opening of said main face in projection (visible at the figure 5 ) makes it possible to obtain a mass per unit area of less than 0.7 mg.mm -2 and, depending on the material used, a weight per unit area decreased to 0.16 mg.mm -2 .
  • the board 25 may, for example, be formed from monocrystalline silicon and coated with silicon dioxide.
  • the inertia of the escape wheel 11 can go down to 1.59 mg.mm 2 .
  • DLC crystalline diamond-shaped carbon
  • the recess 31 of the teeth 30 is substantially of triangular shape in the example illustrated in FIG. figure 5 however, a different form of recess is of course possible.
  • the serge 29 is perforated by spaces 32 between the teeth 30 which are amplified to form an acute angle ⁇ .
  • the serge 29 comprises, from each tooth 30 to the hub 26, recesses 33 in the form of a quadrilateral and, between each recess 33, openings 34 substantially triangular.
  • the frame 35 supporting each tooth 30 is thus triangular in shape, the base 36 being formed by the inner diameter of the serge 29 and connecting by two sides 37, 38 substantially rectilinear associated tooth 30.
  • each frame 35 therefore comprises a recess 33 and two cut-outs 34.
  • each frame 35 is interwoven with the other two adjacent frames 35.
  • each frame 35 has its side 37 intersecting with the side 38 of the previous frame and its side 38 intersecting with the side 37 of the next frame.
  • the side 38 of the previous frame joins the side 37 of the frame substantially at the middle of the base 36 of the frame 35.
  • the watch movement 5 thanks to the adaptation described above of its exhaust system 7 is capable of withstanding a frequency greater than 5 Hz and, in particular, a frequency of 10 Hz.
  • each of the days 31, 32, 33, 34 made in the plate 25 or on the anchor 13 can be of shape different and / or distributed differently and / or not through and / or unformed depending on the applications.
  • the elementary surface of at least one element is projected to a non-identical thickness, that is to say that, for example, the board 25, each arm 16 , 17 or the rod 14 has a variable thickness or not identical to the others.
