Definitions
- the present invention relates to a pendulum-type oscillator for a timepiece, more particularly such an oscillator whose isochronism is improved.
- Isochronism is understood to mean the variations of the gait as a function of the oscillation amplitude of the balance and as a function of the position of the timepiece. The smaller these variations, the more isochronous the oscillator.
- the march of a balance-balance oscillator is equal to the sum of the march due to the lack of equilibrium of the balance and the march due to the balance spring.
- the lack of equilibrium or imbalance of the pendulum disturbs the regularity of the oscillations.
- it is customary to rebalance the balance by milling or by means of adjusting screws fitted to the balance.
- the movements of the spiral are caused mainly by the eccentric development and the weight of the hairspring.
- the eccentric development of the spiral generates a disturbing torque, the same in all positions, created by the restoring forces between the pivots of the oscillator shaft and the bearings in which they rotate.
- the weight of the hairspring generates another disturbing torque, a function of the inclination of the timepiece relative to the horizontal position.
- the present invention aims at proposing another approach to improve the isochronism of a balance-balance oscillator and in particular to reduce the differences of gait between its different vertical positions.
- an oscillator for a timepiece comprising a balance and a balance spring, the balance having a defect of equilibrium, characterized in that the balance defect of the balance and the spiral geometry are such that
- the present invention proposes to design the balance and the hairspring in such a way that the step due to the lack of equilibrium balance and the step due to the weight of the hairspring compensate at least partially and preferably substantially entirely in all or almost all the normal operating range of the balance. Unlike the state of the art, it is therefore not sought in the present invention to cancel the unbalance of the balance, it can even be high. Similarly, there is no attempt to minimize walking due to weight of the hairspring. This new approach makes it possible to obtain very small gaps between the different vertical positions of the oscillator and thus improves the precision of the timepiece.
- the amplitude of oscillation at which the curves representing the oscillator step due to the weight of the hairspring go through zero may be slightly different from one curve to another.
- said curves go through zero at the same amplitude of oscillation and therefore intersect at the same point.
- the balance defect of the balance and the spiral geometry are such that the average slope of each curve of said curves representing the oscillator step due to the lack of equilibrium balance has substantially the same an absolute value that the average slope of the corresponding one of said curves representing the oscillator step due to the weight of the hairspring in the range of oscillation amplitudes from 150 ° to 280 °.
- the lack of equilibrium balance and the spiral geometry may be such that the maximum deviation of the oscillator step due to the lack of equilibrium balance and the weight of the balance between said vertical positions in the range of amplitudes oscillation from 150 ° to 280 ° is less than 4 seconds / day, or even 2 seconds / day, or even 1 second / day, or even 0.7 seconds / day.
- the distance between the inner end of the hairspring and the center of rotation of the hairspring may be greater than 500 pm, or even 600 pm, or even 700 pm.
- the balance of the pendulum can be greater than 0.5 pg.cm, or even 1 pg.cm.
- the inner coil of the spiral has a stiffened portion and / or is shaped according to a Grossmann curve.
- the outer coil of the spiral may also have a stiffened portion.
- the spiral has a rigidity and / or a pitch that varies continuously over at least several turns.

- FIG. 10 shows curves representing the oscillator step due to both the equilibrium defect of the balance and to the weight of the balance spring according to the second embodiment of the invention.
- a balance-balance oscillator for a watch movement intended to equipping a timepiece such as a wristwatch or a pocket watch, comprises a rocker 1 mounted on a rocker shaft 2 and a hairspring 3 whose inner end 3a is fixed to the rocker shaft 2 by via a ferrule 4 and whose outer end 3b is fixed to the frame of the movement via one or more organs.
- the outer end 3b of the spiral 3 is extended by a rigid attachment portion 5 which is held by a clamp 6 mounted on the frame of the movement, as described in EP 178061 1 of the applicant.
- the outer end 3b could however be fixed to the frame in another way, for example by means of a traditional stud.
- the assembly comprising the hairspring 3, the shell 4 and the rigid fastening portion 5 may be monolithic and made for example of silicon or diamond.
- the balance shaft 2 also carries a plate or double plate 7 itself carrying a plate pin 8 and part of an exhaust serving to maintain and count oscillations of the oscillator.
- Spiral 3 does not have the traditional shape of an Archimedean spiral with a constant blade section.
- the geometry of the spiral is indeed irregular in that it has a section and / or a pitch that varies along its blade.
- a portion 3c of the outer turn hereinafter “outer stiffened portion” and a portion 3d of the inner turn (hereinafter “internal stiffened portion”) have a larger section, so a larger great rigidity, that the rest of the blade forming the spiral 3. Outside these portions 3c and 3d the section of the blade is constant.
- the pitch of the hairspring 3 is constant from a point 3e 'located on its inner coil to a point 3e located on its outer turn.
- the end portion 3f of the hairspring 3 extending between the points 3e and 3b comprises at least a portion of, typically all, the outer stiffened portion 3c.
- the inner turn could be shaped according to a Grossmann curve. One could also have no external stiffened portion 3c.
- the section of the spiral blade instead of changing the section of the spiral blade only locally at the inner turn and the outer turn, it could change the section continuously along the length of the blade or several turns, it that is to say on a number (not necessarily integer) of turns greater than 1, for example equal to 2 or more. It would also be possible to continuously vary the pitch of the hairspring all along the blade or on several turns, replacing or in addition to the variation of section. In addition, one could vary the rigidity of the spiral along its blade in another way than by changing its section, for example by doping or heat treatment.
- the progress of a balance-balance oscillator is equal to the sum of the step due to the balance and the step due to the balance spring.
- the pendulum influences walking in vertical positions only.
- the oscillation of the oscillator due to the pendulum is caused by the lack of equilibrium balance, that is to say by the fact that due to manufacturing tolerances, the center of gravity of the pendulum is not on the axis of rotation of the latter.
- the unbalance A of the balance and the angular position Qb of its center of gravity G are adjustment parameters of the step due to the lack of equilibrium of the balance.
- the spiral it influences the march in the horizontal position and in the vertical positions.
- the eccentric development of the spiral causes reactions in the bearings of the balance shaft, which vary in all the positions of the oscillator.
- the displacement of the center of gravity of the spiral caused by the eccentric development of the latter creates a defect of isochronism due to the weight of the spiral applied to said center of gravity. This disturbance is different from the elastic gravitational collapse effect of the hairspring, which is neglected in the present invention.
- the curve representing the progress of the oscillator due to the lack of equilibrium of the balance according to the oscillation amplitude of the balance, in any vertical position of the latter passes through the value zero (c that is, crosses the x-axis) at an oscillation amplitude of 220 °.
- the curve representing the oscillator's step due to the weight of the spiral as a function of the oscillation amplitude of the balance, in any vertical position of the latter passes through the zero value (that is to say crosses the abscissa axis) at oscillation amplitudes of 163.5 ° and 330.5 °.
- the present invention is based on the observation that it is possible to choose parameters A, 0b of rockers and spiral geometries so that the march due to the lack of equilibrium of the balance and the step due to the weight of the balance spring compensate, allowing and to reduce, or to make substantially zero, the differences in the market between the different vertical positions.
- the spiral 3 has 14 turns.
- the thickness eo of the blade forming the hairspring measured along a radius extending from the center of rotation O of the hairspring, is 28.1 ⁇ m, except along the outer stiffened portion 3c and the inner stiffened portion 3d where it is bigger.
- the spiral pitch between points 3e 'and 3e is 86.8 ⁇ m.
- the radius R of the ferrule 4, or distance between the inner end 3a of the spiral and the center O, defined as the radius of the circle of center O passing through the middle (at half the thickness eo) of the end Inner 3a, is 545 ⁇ m.
- the maximum thickness ed of the inner stiffened portion 3d measured along a radius extending from the center of curvature Cd of the beginning of the inner turn (between points 3a and 3e '), is 73 ⁇ m.
- the maximum thickness e c of the outside stiffened portion 3c measured along a radius from the center of curvature of this end portion 3f of the spring 3, is 88 pm.
- the angular extent ⁇ 0 and the angular position a c (position of its center with respect to the outer end 3b of the hairspring 3) of the outer stiffened portion 3c, measured from the center of curvature Ce, are respectively 94 ° and from 1 to 10 °.
- FIG. 4 shows the progress of the oscillator 1, 2, 3 due to the weight of the hairspring 3 as a function of the amplitude of oscillation of the balance 1 in each of four vertical positions of the oscillator spaced 90 ° apart , ie a high vertical position VH (3 hours at the top) (curve S1), a vertical right position VD (12 hours at the top) (curve S2), a vertical left position VG (6 hours at the top) (curve S3) and a low vertical position VB (9 hours up) (curve S4).
- VH 3 hours at the top
- VD (12 hours at the top
- curve S3 a vertical left position VG (6 hours at the top)
- VB (9 hours up) curve S4
- the curves S1 to S4 intersect at a point P1 located on the abscissa axis at an oscillation amplitude of approximately 218 °, which amplitude is therefore close to the amplitude of oscillation of 220 ° to which the corresponding curves of a pendulum meet.
- the part of the hairspring 3 which has the most influence on the position of the crossing point P1 is the internal stiffened portion 3d.
- the outer stiffened portion 3c makes it possible to refine the adjustment of the crossing point P1, and / or to produce a march advance which compensates for a delay caused by the escapement as described in the patent applications WO 2013/034962 and WO 2014/072781 of the present applicant.
- the crossing point P1 or the vicinity of point P1 occurs in all vertical positions of the oscillator.
- FIG. 5 represents the progress of the oscillator 1, 2, 3 due to the lack of equilibrium of the balance 1 as a function of the amplitude of oscillation of the balance 1 in each of the four aforementioned vertical positions of the oscillator, namely the vertical high position VH (curve B1), the vertical right position VD (curve B2), the left vertical position VG (curve B3) and the vertical low position VB (curve B4).
- VH vertical high position
- VD curve B2
- VD vertical right position
- VG right position VG
- VB vertical low position VB
- the diagram of FIG. 5 is that of a balance having an unbalance A of 0.6 ⁇ g ⁇ cm and whose angular position 0b of the center of gravity is 60 °.
- the slope, in particular the average slope, of each curve B1 to B4 is of opposite sign to that of the slope, in particular the average slope, of each curve S1 to S4 respectively.
- the curves S1 and S2 decrease while the curves B1 and B2 increase
- the curves S3 and S4 increase while the curves B3 and B4 decrease. This is particularly true in the operating range of a pendulum in vertical position, namely the range of oscillation amplitudes from 150 ° to 280 °.
- the average slope of each curve S1 to S4 has substantially the same absolute value as the average slope of the corresponding curve B1 to B4 in the range of oscillation amplitudes of 150 ° to 280 °.
- Adjusting the slopes of the curves B1 to B4 during the design of the oscillator is done by varying the unbalance A of the balance and the angular position 0b of its center of gravity.
- varying the angular position 0b of the center of gravity of the balance changes the relative position of the curves B1 to B4. It is therefore advisable to choose a value 0b so that the order of the curves B1 to B4 (according to their slope) is the inverse of that of the curves S1 to S4.
- varying the unbalance A increases or decreases the slope of each curve B1 to B4, which optimizes the degree of compensation between the balance and the hairspring.
- Figure 6 shows the progress of the oscillator due to the lack of equilibrium of the balance and the weight of the balance spring (sum of the step due to the lack of balance of the balance and the step due to the weight of the balance spring) in each of the four above-mentioned vertical positions, namely the vertical high position VH (curve J1), the vertical right position VD (curve J2), the left vertical position VG (curve J3) and the vertical low position VB (curve J4).
- VH curve J1
- VD vertical right position
- VG curve J3
- VB vertical low position VB
- Figure 7 shows a spiral 3 'of the same type as the spiral 3 shown in Figure 2 but whose ferrule radius R was increased from 545 pm to 760 pm.
- the values eo, e c , ed, Qc, Qd, a c , ad, measured in the same way as for the hairspring 3, are as follows:
- FIG. 8 shows the progress of the oscillator 1, 2, 3 'due to the weight of the hairspring 3' as a function of the amplitude of oscillation of the balance 1 in each of the four vertical positions mentioned above, namely the vertical position high VH (curve S1 '), the right vertical position VD (curve S2'), the left vertical position VG (curve S3 ') and the vertical low position VB (curve S4').
- VH curve S1 '
- VD curve S2'
- VD curve S2'
- the left vertical position VG curve S3 '
- the vertical low position VB curve S4'
- FIG. 9 shows the progress of the oscillator 1, 2, 3 'due to the lack of balance of the balance 1 as a function of the amplitude of oscillation of the balance 1 in each of the four vertical positions mentioned above, namely the vertical position high VH (curve B1 '), the right vertical position VD (curve B2'), the left vertical position VG (curve B3 ') and the vertical low position VB (curve B4').
- the diagram of FIG. 9 was obtained with a balance having an unbalance A of 1.25 .mu.g and whose angular position Qb of the center of gravity is 55.degree. It can be seen that the slopes of the curves S1 'to S4' and the slopes of the curves B1 'to B4' allow a step compensation between the balance 1 and the spiral 3 '.
- FIG. 10 shows the progress of the oscillator 1, 2, 3 'due to the lack of balance of the balance 1 and to the weight of the balance spring 3' (sum of the step due to the lack of balance of the balance 1 and the step due to the weight of the spiral 3 ') in each of the four vertical positions mentioned above, namely the vertical high position VH (curve J1'), the vertical straight position VD (curve J2 '), the vertical left position VG (curve J3') and the low vertical position VB (curve J4 '). It can be noted that the operating deviations between these vertical positions are very small, the maximum operating gap in the range of oscillation amplitudes from 150 ° to 280 ° being less than 0.7 s / d.
