Definitions
- a balance spring In mechanical watches, the time is divided into fractions by a regulating member which is usually, to date, a balance spring.
- the latter is composed of three main parts: the pendulum which plays the role of flywheel, a shaft terminated by pivots, which allows to mount the balance in a timepiece frame and a spiral spring that produces a couple proportional return to the angular displacement of the balance.
- the present invention aims to provide an oscillator with the advantages of systems of the state of the art, but at least partially free of their disadvantages.
- the subject of the invention is a virtual pivot rotary oscillator, that is to say without a physical pivot in the usual sense of the term, which comprises a support element intended to enable the oscillator to be assembled on a timepiece, a balance, a plurality of flexible blades connecting the support member to the balance able to exert a restoring torque on the balance, and a serge mounted integral with the balance.
- the plurality of flexible blades comprises at least two flexible blades including a first blade disposed in a first plane perpendicular to the plane of the oscillator, and a second blade disposed in a second plane perpendicular to the plane of the oscillator and secant with the first plane, the first and second blades are of identical geometry, and in that the oscillation geometric axis of the oscillator is defined by the intersection of the first plane and the second plane, said axis geometric oscillation crossing the first and second blades to 7/8 th of their respective length.
- the invention provides a clean rotation, that is to say in which the axis of oscillation is fixed, and without friction, if not those of air.
- This clean rotation makes it possible to produce on the oscillator a return torque that is almost proportional to the angular displacement.
- We obtain a mechanical oscillator capable of offering a great potential for increasing the power reserve of a mechanical watch.
- the figure 1 shows a rotary oscillator 1 for a timepiece according to the invention which comprises a support element 2 intended to allow its assembly on a frame (not shown) of a mechanical watch.
- the oscillator 1 further comprises a rocker 3, which, in this example, comprises a circular-shaped element comprising a central opening, inside which the support element 2 takes place.
- the latter is situated in the plane of the balance 3, close to the center of the balance 3 or its center of gravity in the case of a non-circular balance.
- the support member 2 is connected to the balance 3 by a plurality of flexible blades connecting the support member 2 to the balance 3.
- a serge 4 is mounted integral with the balance 3 to give sufficient inertia to the oscillator 1.
- the figure 1 presents a first embodiment of the invention, wherein there are two flexible blades including a first blade 51 disposed in a first plane perpendicular to the plane of the oscillator 1, and a second blade 53 disposed in a second plane perpendicular to the plane oscillator 1 and secant with the foreground.
- the first 51 and second 53 blades are advantageously of identical geometry.
- the height of the blades is the dimension perpendicular to the plane of the balance 3.
- the length of the blade is naturally the dimension located in the plane of the balance 3, along the longitudinal axis of the blade, and the thickness is the dimension perpendicular to the length, in the plane of the balance 3.
- the thickness is reduced so as to give the blades a flexibility in the plane of the balance 3.
- the height of the blades is defined so as to offer sufficient rigidity to maintain the balance 3 in the same plane as the support member 2 when the oscillator 1 is assembled on the frame.
- the first and second planes intersect along a line that passes 7/8 th of the length of each blade 51 and 53 and which defines a virtual oscillation axis 7 of the oscillator 1.
- the plurality of flexible blades comprises a pair formed of a first 51 and a second 52 blades disposed in the first plane perpendicular to the plane of the oscillator 1.
- the first 51 and second 52 blades are of identical geometry.
- the plurality of blades also comprises a third blade 53 disposed in the second plane perpendicular to the plane of the oscillator 1, and intersecting with the first plane.
- the third blade 53 is interposed between the first 51 and the second 52 blades and has a height twice that of the first 51 or the second 52 blade.
- the figure 4 shows a side view of the flexible blades in which there is clearly the arrangement of the flexible blades and the difference in height of the blades.
- the implementation of a plurality of flexible blades increases the off-plane rigidity of the virtual pivot.
- the geometry of the blades is adapted to maintain the rigidity of the pivot constant while keeping the symmetry of the rigidity with respect to the average plane of the balance.
- the rocker 3 has a shape that allows it to be centered and balanced around the geometric axis of oscillation 7. Also, in the particular configuration illustrated by way of example, if its outer circumference is circular, its inner periphery which defines the central opening, defines a symmetry polygon of order N around the virtual oscillation axis 7. At a first of their end 51A, 52A and 53A, the blades are respectively positioned perpendicular to and in the middle of two sides of the polygon.
- the inner periphery 31 of the balance 3 has a shape resulting from the superposition of a square and a Greek cross, whose arms intersect at their center and are equidistant, the axes of the arms of the cross passing through the angles of the square with identical arms whose angles of the square and the arms of the cross are aligned.
- the support element 2 has two substantially parallel faces, respectively, on both sides of the polygon receiving the blades, so that at their second end 51B, 52B and 53B, the blades are also positioned perpendicular to the faces of the element of the support. They can also be positioned in the middle of said faces.
- the first and second planes containing the blades are perpendicular.
- the face of the support member 2 and the side of the polygon connecting the same blade are parallel.
- the support element 2 makes it possible to assemble the oscillator 1 on the frame (not shown) of a mechanical watch, by means of fixing means 21, for example holes, which can also be shaped so as to provide means indexing the position of the oscillator 1.
- the serge 4 is positioned integrally on the outer periphery of the balance 3. It is made of a material of higher density than the density of the material of the balance 3, in order to give the oscillator 1 sufficient inertia. In the example proposed, serge 4 is a ring, but could consider having a plurality of clubs, distributed regularly around the balance 3.
- the balance 3 comprises a plurality of housings 32, advantageously circular, each receiving a counterweight 6.
- the housings 32 are regularly distributed on the balance 3, and preferably arranged at equidistance of the geometric axis of oscillation 7.
- Each of the weights 6 has a center of gravity positioned eccentrically with respect to each housing 32.
- the rocker 3 is structured so as to define, at each housing 32, an elastic element 33 taking up at least partially in said housing 32.
- the weights 6 are arranged in the housings 32.
- the elastic elements 33 allow to maintain the weights 6, exerting on them a prestressing force generated by the deformation of the elastic elements 33 tending to maintain the weights 6 in their housing 32.
- the support element 2, the balance 3 including the elastic elements 33, and the flexible blades 51, and 53 or 51, 52 and 53 according to the proposed cases, are of monolithic manufacture .
- Such a microsystem 8, illustrated on the figure 3 can be made of silicon, by deep etching techniques. It is thus possible to obtain the precision required for the machining of the flexible blades 51, 52 and 53, which are separated, typically, by only a few microns.
- the microsystem 8 is made of silicon and the serge 4 is made of gold. They are assembled at the wafer level by thermocompression. This allows a much more accurate assembly than by conventional methods.
- a microsystem 8 made of silicon it is possible to compensate for the thermal drift affecting the flexible blades of the oscillator 1 by coating the latter with a coating made of a material having a coefficient of thermal elasticity of the inverse Young's modulus. that of silicon.
- the material chosen is typically SiO 2 .
- the thickness of the coating is determined so as to correct the stiffness constant of the flexible blades 51 and 53, if appropriate 52, to reduce, or even cancel, its dependence on temperature variations. It is also possible, by modulating the stiffness constant of the flexible blades to compensate for the thermal drift of the inertia of the balance 3 so as to obtain an oscillation frequency as independent as possible from the temperature, in the intended field of use.
- the entire outer surface of the oscillator 1 can be oxidized and include a layer of SiO 2 , although the role of this coating is essentially useful on the flexible blades 51, 52, 53.
- the number of flexible blades shown in the examples described above is not limiting and the skilled person will adapt the number of flexible blades and their arrangement according to his needs.
- the maximum number of blades being defined by a compromise between the congestion granted to the system (in particular from an aesthetic point of view) and the stability of the system.
- the blades of a pair may be on the same side of the middle plane or on both sides of this plane.
- the 3-blade embodiment will typically be inspired, with a flexible blade located in the first plane, sandwiched between two pairs of flexible blades located in the second plane, the sum of the heights of the flexible blades. located in the second plane being equal to the height of the flexible blade in the foreground.
