Definitions

  • the present invention relates to a device of the tourbillon type intended to equip a timepiece movement of the type comprising a frame and a finishing gear as well as to a movement or timepiece equipped with such whirlwind.
  • This device is a device intended to moderate walking in vertical positions. It comprises, for this purpose, a cage pivotally mounted on the frame, in general an assembly formed of a bridge and a plate and, mounted pivoting on this cage, a balance spring and an exhaust comprising in particular a mobile exhaust with a wheel and a pinion.
  • the cage has a cage gear, kinematically connected to the gear train finishing of the timepiece, usually at the average wheel.
  • Wheels and gears are, in general, arranged and numbered so as to what the vortex does one revolution per minute. So when the timepiece is positioned vertically, the position of the neutral point of the balance therefore makes a turn per minute, which means the differences in the vertical positions.
  • the German watchmaker Walter Prendel (Groitzsch, Germany) has made a pocket watch in which the axis of the balance makes a angle of 30 ° with that of the tourbillon cage and those of the other mobiles of the shows. In this way, the position of the balance varies from 30 to 60 ° at most when the watch is either in a vertical position or in a horizontal position. But if the walking tests of the watches are done by placing them in different horizontal and vertical positions, the orientations are, on the other hand, when wearing. The problem posed above is modified.
  • exhaust components are also inclined relative to the axis of the cage, the angle of inclination of the axes of these mobiles increasing from the escape wheel to the balance.
  • Such a solution is difficult to master from the technical point of view and the conditions of work of the exhaust are unfavorable.
  • the object of the present invention is to provide a tourbillon for a part watchmaking system to significantly reduce market differences between horizontal and vertical positions, without having to decrease the diameter of the balance, while maintaining a thickness of movement compatible with a pocket watch or a wristwatch.
  • This timepiece movement is characterized by the characteristics set out in Claims 1 to 15.
  • Said angle ⁇ different from 90 °, can be between 20 ° and 70 ° and is preferably equal to 30 °.
  • the pendulum and the mobiles of the exhaust can rotate according to axes parallel to the axis B-B rotation of the exhaust-door cage.
  • the teeth mounted on the frame and which is engaged with the pinion exhaust is either secured to said frame, or carried by a large rotated cage on this frame about an axis A-A forming an angle different from 90 ° with the axis B-B of rotation of the exhaust-door cage.
  • This tourbillon movement is arranged so that, under the effect the torque applied by the finishing gear on the cage gear of the cage exhaust door, the large cage rotates around the first axis A-A at a first angular velocity, and the escape-cage rotates around the second axis B-B at a second angular velocity defined by the ratio of numbers of teeth that comprise the cage gear of the large cage and the tooth of the mobile mounted on the frame, the second axis B-B defining the envelope of a cone of axis coincident with the first axis A-A, or axis of rotation of the big cage.
  • the angle at the apex of the cone generated by the second axis B-B, or axis of rotation of the exhaust door cage is equal to or smaller than 90 °.
  • the most important conditions are obtained for an angle at the apex of 60 °, generally between 20 and 70 °.
  • gears as cage gears, it is possible to make a vortex with mass and inertia as low as possible.
  • the exhaust cage vortex according to the invention can perform a revolution in one minute.
  • the toothing of the mobile mounted on the frame is tapered with the same angle at the top as the cone defined by the second axis.
  • the vortex 16 has two cages 20 and 22.
  • the large cage 20 is illustrated in detail in Figures 2 and 3. It is mounted on the bearings 14.
  • the plate 10 is provided with a drop 24, surrounding the hole where the bearing 14 is housed, which carries an annular wheel plank 25, including a second conical teeth 25a, whose function will be specified later.
  • This board 25 is fixed by means not shown in the drawing, for example by driving or screwing.
  • the drop 24 is provided with a lateral opening 26 allowing the passage of the average wheel 18.
  • the portions 28 and 30 each comprise a middle portion, in the form of a bar identified by the letter a , and two uprights identified by the letter b, the ends of the uprights 28b and 30b being fastened in pairs, by means of the screws 32, and advantageously positioned by means of feet, which have not been shown in the drawing, in order to avoid overloading it.
  • the bars 28a and 30a and the uprights 28b and 30b define a substantially rectangular opening 46, whose width and height are chosen so that the exhaust-carrying cage 22 can be accommodated therein and rotate freely, as will be explained later.
  • the two shafts 34 and 36 each comprise a pivot identified by the letter a and intended to be engaged in one of the 14 levels, and a base identified by the letter b.
  • the plates 34b and 36b are respectively adjacent and fixed, by example by driving or screwing, the middle portion of the bars 28a and 30a.
  • the shaft 34 carries, in addition, a first cage gear 45 fixed by driving and intended to mesh with the average wheel 18.

  • the parts 52 and 54 each comprise a middle bar-shaped portion identified by the letter a and two uprights identified by the letter b , the ends of the uprights 52b and 54b being fixed in pairs by the screws 56 ( Figure 1).
  • the median portions 52a and 54a are pierced with a hole identified by the letter c , of axis coinciding with the axis BB.
  • the shafts 60 and 62 are fixed on the parts 52 and 54 by means of screws 64, schematically represented.
  • the pivot 60b and the pivot 62b are coaxial and oriented along the axis B-B. They are intended to be respectively engaged in the bearings 47 and 50 of the large cage 20, to ensure the rotation of the cage exhaust door 22 in the large cage 20.
  • the second cage gear 60c is arranged in such a way that it meshes with the second toothing 25a of the board 25, integral with the frame 10.
  • the exhaust-carrying cage 22 carries a balance wheel 66 provided with a spiral shown in the drawing, an anchor 68 and an escapement mobile 70 having a pinion 70a and a wheel 70b, the latter cooperating with the anchor 68 for maintain the movement of the pendulum 66. All these mobiles are pivoted on the exhaust-door cage 22 along axes parallel to each other and with respect to the axis B-B of rotation of this cage 22.
  • the rocker arm 66 pivots about an axis concentric with the axis B-B, in two bearings 72 and 73 mounted one 72 in the hole 52c of the portion median 52a, the other 73 in the hole 54c of the median portion 54a.
  • the exhaust bridges 58 and 59 each comprise a bearing 74, in which pivots the escapement 70.
  • the pinion 70a is arranged, so that its toothing protrudes from the lower surface of the portion median 52a, to allow it meshing with the first toothing 48a of the board 48 of the large cage 20.
  • the assembly of a tourbillon as described begins with the assembly of components of the exhaust-carrying cage 22, and more particularly the hunting bearings 72 and 73 and fixing trees 60 and 62.
  • the bridge exhaust 58 is put in place, then the escape mobile 70 and the anchor 68, and finally the exhaust bridge 59, so that the components of the exhaust can pivot in their bearings.
  • the rocker arm 66 is then engaged by its lower pivot in the bearing 72, then positioned by fixing the upper part 54 on the lower part 52, the upper pivot of the balance being engaged in the bearing 73.
  • the two parts 52 and 54 are assembled by means of the screws 56.
  • the starting can then be carried out in a conventional manner, by subjecting the escape wheel 70 to a motor torque, on a suitable posage.

  • the wheel of mean 18 subjects the large cage 20 to a motor torque, by meshing with the first cage gear 45.
  • This pair can not generate a rotation of the large cage 20 that if the second cage gear 60c rolls on the second tooth 25a of the board 25, that is to say that the exhaust-carrying cage 22 rotates around the B-B axis.
  • the teeth of the exhaust pinion 70a is in engagement with the teeth of the first board 48, this movement is not possible than when the escapement gives a driving impulse to the pendulum 66. This is produced at each alternation of the pendulum.
