Definitions
- the present invention describes a time indicator with mechanical regulator according to the definition of the claims. This time indicator is particularly suitable for use in wristwatches.
- the present invention belongs to the family of so-called “vortex” time indicators.
- the classic type of such a time indicator is represented by the “Bréguet tourbillon” from 1795.
- a balance, its spiral spring and its escapement are assembled inside a rotating cage, the speed of rotation of the cage is 60 sec. per turn.
- the whole cage revolves around a gear.
- the present invention aims to compensate for the dynamic and static balancing errors of the balance-spiral-escapement assembly due to geometry, manufacturing problems or due to the asymmetrical beating of the spiral spring.
- the present invention refers to a time indicator of the balance-spiral type, with an oscillation of the balance maintained through an exhaust mobile and with an exhaust anchor resting on an exhaust bridge, characterized by a mobile exhaust partially carrying the balance and the spiral spring, by an axis of the oscillator mounted on a movable lower bearing arranged integrally with the exhaust movable and mounted on a fixed upper bearing. Most of the energy is transmitted by an escape anchor. This exhaust anchor is supported indirectly on an exhaust bridge.
- the invention Compared to a time indicator with a mechanical regulator of the traditional so-called “tourbillon” balance-spiral type, the invention has the following advantages:
- the time indicator has a construction without a rotating cage and without double bearings, thus allowing a particularly simple and robust construction, requiring fewer elements.
- the efficiency of the exhaust is greater, so as to allow the use of a weaker barrel spring or the realization of a greater power reserve.
- - fig. 1 shows a sectional view of a time indicator with a regulator known as a “tourbillon”,
- - fig. 2 shows a top view of an exemplary embodiment of a time indicator with regulator according to the invention
- FIG. 3 shows a side view in section of a detail of an exemplary embodiment of a time indicator with regulator according to FIG. 2.
- Fig. 1 shows a sectional view of a so-called “tourbillon” regulator time indicator with spiral balance.
- a balance, its spiral spring and its exhaust are assembled inside a rotating cage, the rotation speed of the cage is 60 sec. per turn.
- the whole cage revolves around a gear.
- the oscillation of the balance is maintained through the escapement by a pulse force applied directly to the oscillator at the time of its passage at point 0.
- This transmission of a pulse force to the balance can be done alternately or unidirectional depending on the type of exhaust. It should be noted that to reduce the disturbances of the oscillator, the pulse time must be minimal.
- the quality factor of the oscillator is directly proportional to the frequency of said oscillator.
- Figs. 2 and 3 show different detail views of an exemplary embodiment of a regulator time indicator according to the invention.
- Fig. 2 shows a top view and fig. 3 shows a sectional side view.
- an intermediate wheel 1 is provided for transmitting a driving torque of a barrel spring to an exhaust mobile 2.
- the exhaust bridge 4 is of special shape, hollowed out and concentric with a pendulum 7 With an escape anchor 3, an escape wheel 12 and an escape pinion 13, this escape bridge 4 serves as support and limitation to a rotation of the exhaust mobile 2.
- a first end of this spiral spring 6 is fixed by a fixing peg 5 to the exhaust mobile 2. Another end of this spiral spring 6 is fixed by a point to the balance 7.
- the exhaust mobile 2 has a lower bearing and an upper bearing arranged concentrically with the balance 7.
- the lower bearing is movable and integral with the exhaust mobile 2.
- the upper bearing is fixed. This exhaust mobile 2 integrally drives an exhaust anchor 3 and the fixing stud 5 of the spiral spring 6.
- the exhaust anchor 3 can tilt around its axis, allowing rotation of the exhaust mobile 2.
- the escape wheel 12 is integral with the exhaust pinion 13 which engages on the bridge of exhaust 4, thereby limiting the angle of rotation of the exhaust mobile 2 preferably unidirectional through the exhaust anchor 3.
- the exhaust pinion 13 makes a continuous movement relative to the exhaust bridge 4
- the exhaust anchor 3 bears indirectly on the exhaust bridge 4 and indirectly releases the rotary movement of the exhaust mobile 2. Bare from this construction, most of the energy is transmitted by the escape anchor 3. By comparing the present invention, it can be seen 01/59529 - 5 -
- the fixing stud 5 of the spiral spring 6 being integral with the exhaust mobile 2. D transmits to the spiral spring 6 the angular movement which it has just been animated, storing potential energy in the spiral spring 6 which will initiate the oscillation balance 7.
- a track 8 driving the escape anchor 3 is integral with the balance 7.
- This track 8 is positioned in such a way, which initiates the tilting of the escape anchor 3 when the balance 7 passes at point 0 of the 'oscillation.
- Said tilting of the exhaust anchor 3 releases the fulcrum of the exhaust anchor 3 on the pinion 13 which is integral with the escape wheel 12 and allows limited angular rotation of the exhaust mobile 2 by a next point of support of the escape anchor 3 on this escape wheel 12.
- the fixing peg 5 of the spiral spring 6 being integral with the exhaust mobile 2. Said fixing peg 5 transmits to the spiral spring 6 the angular movement which it has just been animated, storing potential energy in the spiral spring 6 which will maintain the oscillation of the balance 7.
- the time regulator has only a limited influence to guarantee its reliability.
- the oscillation frequency of the balance can be adjusted by moving at least one adjustment mass 9 being arranged for example in an oval shaped gouge machined in the balance 7. This displacement modifies the moment of inertia of the balance assembly- adjustment mass and thereby the frequency of oscillation.
- the speed of rotation of the balance-spiral-exhaust assembly 2,6,7 even is fast and makes 20 to 60 seconds per revolution.
- Those skilled in the art, knowing the present invention, can of course make other balance-spiral-escapement assemblies having higher rotational speeds, for example 10 to 20 seconds per revolution, or lower, for example 60 to 80 seconds per revolution.
- the value of the angle of rotation of the exhaust mobile 2 depends on the direction of passage of the track 8 of the escape anchor 3, the geometry of the escape anchor 3, the escape wheel 12, the exhaust pinion 13 and the angle of freedom of the exhaust anchor 3 on the exhaust mobile 2.
- -Q can be variable depending on the direction of passage of the balance 7 and allows alternating movement ( symmetrical or asymmetrical) or a unidirectional movement of the exhaust mobile 2 according to the period of oscillation of the balance 7.
