Definitions

  • the present invention relates to a tourbillon timepiece mechanism comprising a cage, means for pivoting this cage on a frame of the timepiece, a kinematic connection between the axis of this cage and a motor barrel , a balance spring pivoted in the center of this cage and an exhaust mechanism engaged with this balance spring, the pinion of the escape wheel of this exhaust mechanism being engaged with a toothing integral with said frame.
  • the mechanisms of tourbillon timepieces have been known since the beginning of the 19 th century and are intended to rotate the balance-spring around its axis, so as to reduce the disturbing effects due in particular to the asymmetry of the balance-spring. balance.
  • the tourbillon forms an independent module, intended to be assembled separately before being mounted on the timepiece.
  • the assembly of this module, the exhaust pinion of which must engage with a fixed toothing is made difficult, given the small space available to bring this module into the position it must occupy in the clockwork mechanism.
  • the difficulty of this assembly increases the risk of damaging elements of this tourbillon module which are the most fragile in the timepiece.
  • the object of the present invention is to remedy, at least in part, the above-mentioned drawbacks.
  • the subject of the present invention is a tourbillon timepiece according to claim 1.
  • I1 consists in forming an assembly comprising the balance spring and the escapement mounted in a tourbillon cage of generally circular shape, which is pivotally mounted around an axis passing through the center of this cage.
  • the pivot axis of this cage is secured to a toothed mobile gear engaged with a wheel of the watch gear train and the pinion of the escapement wheel is engaged with a fixed toothed mobile which generally corresponds to the wheel. seconds, so that the tourbillon cage rotates in 60 seconds.
  • a plate 1 to which a bridge 2 is fixed.
  • a wheel of the gear train 3 here the medium wheel, is pivotally mounted between the plate 1 and the bridge 2.
  • This wheel 3 is connected as usual, via a center wheel to a barrel (not shown) which contains a motor spring for driving the gear train of which wheel 3 is part, as in all mechanical watches.
  • the bridge 2 also carries a rolling bearing 4.
  • the internal part of this bearing 4 is integral with a pinion 5 engaged with the wheel 3 and it is fixed to a core 6 by four screws 7.
  • This core 6 is integral with a first perforated plate 8 of the tourbillon cage.
  • This perforated plate is connected by three pillars 9 to a second perforated plate 10. Fixing screws 11 screwed into the pillars 9 fix the two perforated plates 8, 10 to each other.
  • the center of the second plate 10 carries a bearing 12 for the axis of the balance 13 around which a racket 14 carrying the racket pins 15 is frictionally mounted to allow the active length of the balance spring 16 to be adjusted.
  • the end of the balance spring is fixed to the stud 17.
  • a bridge 18 is still attached to the core 6 of the tourbillon.
  • the anchor 19 and the escape wheel 20 are pivotally mounted between the first perforated plate 8 of the tourbillon and the bridge 18.
  • the pinion 20a of the escape wheel 20 meshes with the internal toothing of a crown 21 which constitutes the second wheel.
  • This toothed ring 21 is integral with an annular element 21a fixed to the plate 1 by two screws 22a, 22b diametrically opposite.
  • the screw 22b passes through an elongated opening 23, which makes it possible to move the ring gear 21 and the annular element 21a around the fixing screw 22a which constitutes their pivot axis.
  • the angular displacement of the toothed ring 21 around this fixing screw 22a is controlled by an eccentric 23 which is mounted in a circular opening 24 formed in a part 25 integral with the annular element 21a.
  • a stop 26 serves to determine the limit position of engagement between the teeth of the toothed ring 21 and that of the pinion 20a.
  • the ring gear 21 can occupy two angular positions around the fixing screw 22a.
  • One of these positions is represented by FIG. 3 and corresponds to the position in which the exhaust pinion 20a meshes with the ring gear 21, the pinion 5, integral with the core 6 of the vortex, being driven by the mean wheel 3 of the gear train for finishing the timepiece.
  • the position of the escapement wheel 20 around the balance wheel axis 13, which is also that of the tourbillon, is located to the left of the right connecting the fixing screw 22a to the fixing screw 22b, that is to say in the part of the ring gear 21 where its toothing deviates from that of the exhaust pinion 20a.
  • This angular displacement of the toothed ring 21 facilitates the removal and the positioning of the tourbillon and thus reduces the risks of damaging the parts of the tourbillon.
  • the eccentric 23 is rotated in the opposite direction to bring the ring gear 21 back into the position illustrated in FIG. 3 where it meshes with the exhaust pinion 20a. Finally, the two screws 22a and 22b are tightened.
