Definitions
- the present invention relates to a mechanical movement watch and its object is the reduction of gait deviations which result from the effects produced by gravity on the regulating members of the watch, because of the inevitable defects of balancing these organs, and the variation of these effects in the different positions that the wearer imposes on his watch.
- the tourbillon invented two centuries ago by Abraham-Louis Breguet is a device that leads to such a reduction.
- the oscillator and the escapement being mounted in a cage which rotates about an axis parallel to the axis of the balance-hairspring assembly, the component of the gravity which is exerted in the plane perpendicular to these axes effects relative to these bodies a continuous rotation, so that each tower of the cage leads to a compensation of the effects of the imbalances in this plane and thus improves the regularity of operation of the watch to wear, especially when the watch is in a vertical or inclined position .
- Vortex both devices in which the axis of the balance coincides with the axis of rotation of the cage (for example according to Breguet or according to patent CH 262017) and devices often called “carousels", where these axes are distinct (see for example patents CH 30 754, CH 256 590 and EP 846 987). Since a classical vortex only imperfectly compensates for the effects of gravity, watchmakers seeking to further improve the isochronism of high quality mechanical watches have imagined vortices with two or three mutually perpendicular axes of rotation, described in particular in patent publications GB 2027 232, CH 693 832, EP 1 465 024 and WO 2004/077171.
- Patent FR 2 784 203 presents yet another way of reinforcing the compensation produced by the vortex. This one, the barrel which drives it and the gear linking these two elements are mounted on a turntable making a turn by hour, whose axis of rotation is parallel to that of the vortex.
- the basic idea of the present invention is to reduce the gapping differences of a tourbillon watch in a different manner from that just mentioned and in particular to avoid a thickness excessive movement and therefore the watch.
- An additional goal is to create a watch with a new look, highlighting the high technicality of its movement.
- the subject of the invention is a mechanical movement watch comprising two vortices which are mounted on a common rotating support and are coupled by gear trains to one and the same median element, the rotating support being driven by a source of power. mechanical energy and connected to an analog time display device.
- said median element is formed by a differential gear, which can be centered on the axis of rotation of the rotating support, but other coupling modes of the two vortices can be envisaged.
- the present invention reduces the differences in walking by using a time base whose frequency is the average of those of two swirls mounted on a common support.
- the fact that the common carrier carrying the two vortices is a turntable adds the compensatory effects provided in the patent FR 2 784 203 to further improve the regularity of the watch.
- the axes of the two vortices can be parallel and the two pendulums can be in the same plane, so that the thickness of the movement can be comparable to that of a classic tourbillon movement.
- the principle of the invention to achieve a movement comprising two vortices whose pendulums are each inclined at a small angle with respect to the general plane of the watch, but in opposite directions so as to form between them a total angle sufficient to better compensate the imbalances in different planes, without increasing noticeably the total height of the movement.
- FIG. 2 is a block diagram of a tourbillon watch movement
- FIG. 2 is a schematic diagram of a two-tourbillon watch movement
- FIG. 3 is a schematic plan view of the movement and the dial of a watch according to FIG.
- FIG. 4 is a partial cross-sectional view of the movement of the watch of FIG. 3
- FIG. 5 is a plan view of the gear trains located in the plane of FIG. above the turntable of the watch of Figure 3, and a time setting wheel arranged under the fixed plate.
- FIGS. 1 and 2 respectively represent a classic tourbillon watch movement and the preferred embodiment of a watch. two vortices according to the invention. Reference is made to the following legend: A Display B, B1. B2 Barrel D Differential gear F Finishing wheel MH Time setting T. T1. T2 Tourbillon R Reassembly In these diagrams, simple arrows characterize gear trains without transmission of energy to the oscillators, while double-line arrows characterize gear trains with energy transmission to the oscillators.
- the symbol T can represent both a vortex an ordinary mechanical oscillator, and also that in a well-known variant, the display A can be derived directly from the barrel B rather than from the finishing gear F.
- the energy required for the regulating system comprising the two vortices is provided by two barrels B1 and B2 operating in parallel, but one could also consider use series-coupled barrels or a single large barrel. The energy passes through a display train A and a differential gear D which distributes it between two vortices T1 and T2.
- FIG. 3 to 5 show a preferred embodiment of the invention, operating according to the diagram of Figure 2 and wherein the differential D and vortices T1 and T2 are mounted on a rotating support.
- the movement of the watch comprises a fixed plate 10 to be mounted in a not shown box.
- the top we will designate here the top as the side of the watch where the time is displayed. It is on this side that are also the two vortices 11 and 12, which are identical in this example.
- the pinion 16 is engaged with a wheel 18 hours and, as usual, it carries a wheel 19 meshing with a pinion of minutes 20 to turn it twelve times faster than the hour wheel 18.
- the winding of the barrels is not shown here, but a person skilled in the art will understand that he can use a gear that meshes with the two ratchets mounted on the shafts of the barrels, since the two barrels acting in parallel always have the same armor.
- the two vortices 11 and 12 are mounted on a rotatable support 21 comprising a turntable 22, a central bridge 23 and an upper bar 24, one pointed end 25 of which constitutes the watch hour hand, moving opposite a turn of hours located on an annular dial 26.
- the other end of the bar 24 is provided with an annular portion bearing a graduation of seconds 28.
- the cage of each vortex 11, 12 has an upper pivot which is mounted in a bearing 29, 30 of the bar 24.
- the pivot of the second vortex 12 further carries a seconds hand 31 which rotates next to the graduation 28 each vortex here making a complete revolution per minute on the rotating support 21. The latter makes a turn in twelve hours, which makes it possible to fix the hour hand 25.
- each vortex 11, 12 is mounted in the turntable 22 by a respective bearing not referenced and comprises a drive pinion 33, 34 integral with the cage.
- This pinion plays the role of the pinion seconds of a classic movement.
- Each pinion 33, 34 is engaged with a finishing train comprising a moving average 34, 36 and a mobile of medium 37, 38 whose pinion 39, 40 receives the torque for driving the respective oscillator.
- each pinion 39, 40 moving with the rotation of the turntable 22, rolls on a central gear of the differential gear D centered on the axis of rotation 44 of the plate 22.
- the turntable 22 is supported on the fixed plate 10 by a single bearing formed by a large ball bearing 46, the inner ring is clamped between the plate 22 and the hour wheel 18 by screws 47.
- the total torque of the two barrels 13 and 14 acting on the elements 16 and 18 rotates the plate 22 carrying the two vortices 11 and 12 and their respective second wheels 49 and 50, which are fixed on the plate 22.
- This is the revolution of the axes of rotation 51 and 52 two vortices around the central axis 44 which rotates the mobile 35 to 38 of the two work-trains by rolling them on the middle element formed by the differential gear, thus causing the rotation of each vortex around its prop re axis.
- the differential gearing D is here of the epicyclic type, with for example three double satellites 54 mounted on a planet carrier 55 whose external toothing meshes with the pinion 40 of the finishing gear of the second vortex 12.
- a first toothing 56 of the The satellite meshes with an external toothing 57 of a stationary gun 58 which constitutes the support element, normally fixed, of the differential gear.
- the barrel 58 can pivot about the central axis 44 for setting the time of the watch, as will be described later, and that is why it is rotatably mounted by a lower ball bearing 60 in a fixed bridge and by an upper ball bearing 61 in the bridge 23, and it is provided with a setting pinion 62 below the fixed plate 10.
- the third central element of the gearing differential D is an output wheel 63 having an external toothing which meshes with the pinion 39 of the finishing train of the first vortex 11.
- the outside diameter of the wheel 63 is the same That of the planet carrier 55.
- the wheel 63 is rotatably mounted on the barrel 58 and has a pinion 64 which meshes with the second toothing 65 of each satellite.
- the teeth 56 and 65 of the satellites and the corresponding teeth of the elements 58 and 63 are such that the elements 55 and 63 can rotate at equal speeds, but opposite, when the barrel 58 is stationary.
- the differential gearing D has the effect of averaging these two speeds in the speed of revolution of the platinum 22 bearing the bearings of the workings gears and vortices. This is how we get a smoothness that is better than that of each vortex.
- the rotation of the turntable 22 carrying the hour wheel 18 is transmitted by the minute wheel 16, 19 to the minute gear 20 fixed to a shaft 70 carrying the minute hand 71 and rotatably mounted in the barrel 58.
- the hours 25 and minute hands 71 display the time in the usual manner on the dial 26, while the seconds display by the needle 31 and the graduation 28 performs a twelve-hour revolution around the dial.
- FIG. 5 shows a time-setting train 74 comprising a wheel 75 which meshes with the time-setting gear 62 shown in FIG. 4.
- This gear train located under the fixed plate 10 can be actuated in the usual manner by a control rod 73 ( Figure 3) provided with a ring on the outside of the watch.
- This rod actuates a return wheel 76 meshing with the wheel 77 of a mobile 78 whose pinion 79 rotates the wheel 75.
- the mobile 78 is immobilized on the plate 10 by a friction device whose limiting torque can be relatively low, while ensuring a high retaining torque on the barrel 58 through the multiplication of torque between the mobile 78 and the wheel 62.
- a friction device whose limiting torque can be relatively low, while ensuring a high retaining torque on the barrel 58 through the multiplication of torque between the mobile 78 and the wheel 62.
- one or each of the vortices T1, T2 appearing in the Figure 2 may be a tourbillon with several axes of rotation, in particular of one of the types mentioned in the introduction.
- a person skilled in the art can also design a movement with more than two swirls by applying the principles of the present invention, since a suitable differential gear can couple more than two swirls mounted on the rotating support, so as to average their speeds on the display of the watch. Moreover, even if the two vortices have the same nominal frequency in the example described above, it is not essential, because a suitable dimensioning of the workings and or differential D allows to properly average two different nominal frequencies.
