- the shafts 60 and 62 are fixed on the parts 52 and 54 by means of screws 64, diagrammatically shown.
- 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 escapement cage 22 in the large cage 20.
- the second cage pinion 60c is arranged so that it meshes with the second toothing 25a of the board 25, integral with the frame 10.
- the escapement cage 22 carries a balance 66 provided with a hairspring not shown in the drawing, an anchor 68 and an exhaust mobile 70 comprising a pinion 70a and a wheel 70b, the latter cooperating with the anchor 68 to maintain the pendulum movement 66. All these mobiles are pivoted on the escapement cage 22 along axes which are parallel to each other and relative to the axis BB of rotation of this cage 22.
- the pendulum 66 pivots about an axis concentric with the axis BB, in two bearings 72 and 73 mounted one 72 in the hole 52c of the middle portion 52a, the other 73 in the hole 54c of the middle portion 54a.
- the exhaust bridges 58 and 59 each comprise a bearing 74, in which the exhaust mobile 70 pivots.
- the pinion 70a is arranged, so that its teeth protrude from the lower surface of the middle portion 52a, to allow its meshing with the first toothing 48a of the board 48 of the large cage 20.
- the mounting of a tourbillon as described begins with the assembly of the constituent parts of the escapement cage 22, and more particularly the driving of the bearings 72 and 73 and the fixing of the shafts 60 and 62.
- the exhaust bridge 58 is put in place, then the exhaust 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 pendulum 66 is then engaged by its lower pivot in the bearing 72, then positioned by the fixing of 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 exhaust mobile 70 to an engine torque, on an appropriate fitting.
- the escapement cage 22 can then be placed in the lower part 28 of the large cage 20, the pivot 60b being engaged in the bearing 47.
- the part upper 30 is then fixed by means of screws 32 on the lower part 28, the pivot 62b being engaged in the bearing 50.
- the vortex 16 is thus finished and can be placed on the frame, between the plate 10 and the bridge 12, the pivots 34a and 36a each being engaged in one of the bearings 14.
- the medium wheel 18 subjects the large cage 20 to a driving torque, by meshing with the first cage pinion 45.
- This torque can only generate a rotation of the large cage 20 if the second cage pinion 60c rolls on the second toothing 25a of the board 25, that is to say that the escapement cage 22 rotates about the axis BB.
- the toothing of the exhaust pinion 70a is in prijse with the toothing of the first board 48, this movement is not possible
- the axis BB scans the envelope of a cone of axis AA, whose angle at the apex is approximately equal to 60 °, that is to say twice the angle a that make the axes AA and BB together.
- the pendulum axis has an average inclination of between 20 ° and 70 ° approximately, which considerably reduces the differences in running between the positions.
- the angle at the top of the cone can vary depending on the construction of the watch. The higher the angle, the more space the cage 22 occupies in thickness, unless the diameter of the pendulum 66 is reduced. The tests carried out seem to show that the optimum is in the range of 40 ° to 140 ° for the angle at the top, and more precisely in the vicinity of 60 °.
- the second conical toothing 25a of the wheel 25 has an apex angle equal to that of the cone generated by the rotation of the axis BB around l 'axis AA.
- the tourbillon as described, can of course be the subject of numerous variants without departing from the scope of the invention.
- the cage pinions 45 and 60c could be replaced by wheels meshing respectively with a mobile of the gear train and with the board 25, which would then advantageously be provided with internal toothing. This makes it possible to obtain an opposite direction of rotation of the two cages.
- the pinion 60c which could include a conical toothing, the toothing 25a of the wheel 25 then being straight. It is also possible to distribute the taper between the two teeth.
- the axes of the mobiles of the gear train are parallel to the axis A-A of rotation of the first cage, which could not be the case in other variants.
- the rotational speeds of the cages 20 and 22 can be equal or different.
- the direction of rotation of the cages 20 and 22 can be the same or opposite.
- the large cage has only a lower portion 28 pivoted overhanging on the frame 10 by a bearing 14 following the axis AA parallel to the axes of the mobiles of the gear train.
- This lower part 28 of the large cage 20 carries, as in the first embodiment, a lower support 40 pierced with an axis hole BB inside which is driven a bearing 47 intended to receive the carrier cage exhaust 22.
- the exhaust holder cage 22 also has only its lower part 52 and is pivoted in overhang on the large cage 20 by its lower shaft 60 carrying at the end the second cage pinion 60c meshing with the second toothing 25a secured to the frame 10.
- This variant makes it possible to achieve the same advantages of the tourbillon while having a reduced bulk.
- the tourbillon type device also includes a large cage 20 and an escapement cage 22 as described in the first embodiment or its variant, and the exhaust pinion 70a is also in engagement with the first toothing 48a disposed in a plane perpendicular to the axis (BB) of the escapement cage.
- this toothing 48a is carried by a board 48 mounted on the pyramidal base 40 of the large cage 20 concentrically with the axis BB of the escapement cage 22.
- the first cage pinion 45 of the large cage is as previously engaged with the wheel 18 of the finishing mobile generally the average mobile.
- the large cage is designed as a carousel and the cage pinion 60c of the escapement cage is engaged with one of the wheels 80a of a mobile 80 pivoted on the frame 10, the second wheel 80b of which is it engaged with a second wheel 18a of the finishing mobile.
- the device comprises a vortex comprising in fact only one cage, the escapement cage pivoted in an inclination relative to the frame 10, and the large cage 20 forms a carousel which carries i
- the escapement cage in its rotation controlled by the driving train of the movement.
