Definitions
- the present invention relates to a mechanical watch oscillator with flexible guidance, intended to oscillate around a virtual oscillation axis, said oscillator comprising a movable part centered on the oscillation axis, a fixing part intended to be fixed to a first support element, and at least first and second elastic blades connecting the movable part and the fixing part and arranged to exert on the movable part, relative to the fixing part, a restoring torque.
- Such oscillators also called flexible pivot oscillators, are designed to pivot without a physical axis of rotation, therefore without friction, around a virtual axis of rotation, thanks to an arrangement of elastic parts.
- pivots with separate crossed blades pivots with non-separated crossed blades or pivots with a remote center of rotation called “RCC” (Remote Center Compliance).
- RRC Remote Center Compliance
- oscillators have one or more flexible blades, generally monolithic with the moving part and the fixing part, replacing the hairspring and the physical oscillation axis. These oscillators are particularly interesting in terms of friction reduction.
- operating stops are generally positioned outside the oscillator in order to be able to act on its moving part.
- This type of construction with a shaft or a central material element requires the production of blades comprising a recess, a clearance or an eye provided around the shaft or the central material element, allowing the passage of said shaft or material element. central material without contact with the blades.
- This has the disadvantage of increasing the complexity of designing and manufacturing the blades. This also has the negative effect of reducing the effective length of the blades for a given size, and therefore reducing their stiffness.
- the present invention aims to remedy these drawbacks by proposing a flexible guided oscillator which is ensured in all radial and axial positions, while retaining the advantages of a flexible guided oscillator.
- the flexible guided oscillator according to the invention allows, by means of a single tenon integrated in the central hub of the reported balance, to obtain stops in all directions X, Y, Z, over a small diameter, which has the advantage of reducing the friction torque and disturbances.
- the balance wheel is arranged to constitute the inertial element of the oscillator.
- This advantageously makes it possible to dissociate the inertia of the oscillator from the stiffness of the elastic blades, thus making it possible to adjust the inertia of the oscillator in an easy and known manner via the reported balance, as for a standard balance, and an embodiment blades to the desired stiffness, without sizing constraints of the blades to obtain the good stiffness/inertia compromise usually sought in standard flexible guided oscillators.
- the oscillator is such that its mobile part has a shape arranged to define an interior zone empty of any element of material of the mobile part or it does not include a physical shaft passing through the mobile part and/or the elastic blades.

- the straight line passing through the point P and perpendicular to the plane of oscillator 1 constitutes the axis of oscillation A of the movable part 2 relative to the fixing part 3.
- said movable part 2 oscillates around the axis A relative to the fixing part 3, the elastic blades 5 , 6 exerting on the mobile part 2, relative to the fixing part 3, a restoring torque like the hairspring of a balance-spring oscillator.

- One of the ends of an elastic blade is fixed on said second annular portion, the other end of the elastic blade being fixed on the corresponding fixing part element.
- This embodiment in several parts advantageously makes it possible to manufacture, on the one hand, in a monolithic manner a first stage corresponding to the first element 2a of the movable part, to the first element 3a of the fixing part and to the first blade 5, and on the other hand leaves a second stage corresponding to the second element 2b of the movable part, to the second element 3b of the fixing part and to the second blade 6.
- This allows each stage to be manufactured on a single level, which is advantageous in the context of a manufacturing of silicon elements by DRIE.
- This also makes it possible to have a real physical separation of the blades 5 and 6, obtained more easily than with monolithic manufacturing of a moving part in a single element.
- the first and second stages are superimposed and assembled by pins 20.
- the serge 10 is then assembled to the movable part 2 by means of pins 20 then the weights 22 are put in place in order to obtain the appropriate inertia.
- the first and second annular portions of the elements 2a, 2b of the movable part 2 have diameters different from the diameter of the serge 10.
- This shape of the elements 2a, 2b of the movable part 2 is particularly suitable so that the elastic blades 5 and 6 can have the length necessary to present the required stiffness.
- the mobile part 2 is made of silicon and the rim 10 is made of CuBe for example, so that the inertial element of the oscillator 1 is constituted by the balance 8, making it possible to dissociate the inertia from the oscillator 1 of the stiffness of the blades 5, 6.
- the oscillator according to the invention can also include more than two elastic blades.
