Definitions

  • the invention relates to watch movements comprising an escapement provided with an anchor cooperating, on the one hand, with an escape wheel and, on the other hand, with a mechanical resonator, the anchor having a different axis of rotation from that of the mechanical resonator.
  • the invention relates to a watch movement provided with an escapement comprising a magnetic coupling system between an escape wheel and an anchor.
  • the anchor presents an alternating movement which is synchronous with the periodic movement of the mechanical resonator, but different.
  • Magnetic escapement means an escapement provided with magnets arranged partly on the lever and partly on the escapement wheel so as to generate a magnetic coupling between the lever and the escapement wheel.
  • the Swiss lever escapement has been known for a very long time.
  • the teeth of the escape wheel cooperate with two pallets of the lever in a determined manner allowing a step-by-step rotation of the escape wheel which is synchronous with the oscillation of the mechanical resonator, namely generally a balance-spring.
  • the sustaining pulses generated by the escapement and transmitted to the resonator gradually decrease in intensity so that when the wheel d escapement ends up stopping when said torque becomes less than a limit value, the energy stored in the resonator is relatively low.
  • the document CH 703 449 A2 describes an escapement mechanism in which the lever rod can deform elastically outside the plane of the lever during axial shocks on the balance wheel axis. It is still known from the demand CH 703 476 A2 , elastically deformable anchors, in particular using slots created on the horns of said fork.
  • the sustain pulses are magnetic pulses having a constant value as long as the force torque supplied to the escape wheel is greater than or equal to a certain lower limit. Then, as soon as said force torque is below this lower limit, the escape wheel can no longer properly climb the next ramp of magnetic potential energy, so that the escape wheel will not stop in a next normal stop angular position, but substantially at the bottom of or along a magnetic potential energy ramp.
  • the present invention relates to a watch movement comprising a mechanical resonator, in particular a balance-spring, and an escapement, associated with this mechanical resonator, which is formed by an escape wheel comprising a plurality of projecting parts, in particular teeth, and by an anchor provided with a fork, intended to cooperate with a pin of the mechanical resonator, and with two mechanical pallets which are intended to cooperate with the plurality of teeth at least in a certain phase of operation of the watch movement.
  • a mechanical resonator in particular a balance-spring
  • an escapement associated with this mechanical resonator, which is formed by an escape wheel comprising a plurality of projecting parts, in particular teeth, and by an anchor provided with a fork, intended to cooperate with a pin of the mechanical resonator, and with two mechanical pallets which are intended to cooperate with the plurality of teeth at least in a certain phase of operation of the watch movement.
  • This horological movement is arranged in such a way that, when the lever tilts from a first of its two rest positions towards the second rest position while the escape wheel is positioned in any angular position ⁇ of a plurality of ranges of angular positions corresponding respectively to the plurality of protruding parts, one of the two mechanical pallets of the anchor abuts against one of these protruding parts before this anchor can reach the angular position of disengagement of the pin, integral with the mechanical resonator, on the side of the second rest position.
  • the anchor is arranged so as to be able, during said rocking of the anchor, to bend, in a general plane of the anchor parallel to its fork, by undergoing an elastic deformation under the action of a force exerted by the pin of the mechanical resonator, engaged in the fork, on one of the two lugs of this fork while said mechanical pallet abuts against said projecting part and the mechanical resonator is braked by the lever.
  • this anchor has an elastic capacity, between each of the two mechanical pallets and the fork, allowing it to absorb in the form of elastic energy, during said elastic deformation, a maximum mechanical energy that the mechanical resonator can have during normal operation of the watch movement.
  • the escapement comprises a magnetic system magnetically coupling the escapement wheel and the lever, this magnetic system being arranged so as to generate, during normal operation of the watch movement, magnetic pulses having an energy substantially constant to maintain an oscillation of the mechanical resonator via an interaction between the pin of this mechanical resonator and the fork of the anchor.
  • said magnetic pulses are generated at the level of the two mechanical pallets which respectively support two magnets forming two magnetic pallets.
  • the anchor is arranged so as to be able, during normal operation of the watch movement, to substantially transmit a torque of magnetic force generated by each of the magnetic pulses to its fork to maintain oscillation of the mechanical resonator.
  • a main embodiment of a watch movement according to the invention will be described below, which is of the mechanical type and comprises a mechanical resonator 2, of which only the axis 4, the small plate 6 having a notch and the pin 10 have been shown.
  • the watch movement includes an escapement 12 which is associated with the mechanical resonator whose small plate and peg are elements forming this escapement.
  • the escapement 12 further comprises an escape wheel 16 and an pallet 14 which is a separate member from the mechanical resonator and whose single axis of rotation is different from that of this mechanical resonator.
  • the anchor 14 is formed, on the one hand, of a rod 20 terminated by a fork 18, comprising two horns 19a and 19b, and by a dart 8 and, on the other hand, of two arms 24 and 26 whose free ends respectively form two mechanical pallets 28 and 29.
  • the two mechanical pallets respectively support two magnets 30 and 32 which form two magnetic pallets of the anchor 14.
  • the mechanical resonator 2 is coupled to the anchor so that, when the resonator mechanism oscillates normally, this anchor undergoes an alternating movement, synchronized with the oscillation of the mechanical resonator, between two rest positions, defined by two limiting pins 21 and 22, in which the anchor remains alternately during successive time intervals.
  • the escapement wheel 16 comprises a periodic magnetized structure 36 which is arranged on a disc 34, preferably made of non-magnetic material (which does not conduct magnetic fields in such a way as not to make the escapement wheel sensitive to external magnetic fields which could exert a significant torque on this escape wheel if this disc was made of ferromagnetic material).
  • the structure 36 has magnetized portions 38, globally in an arc of a circle, which define increasing ramps of magnetic potential energy for the two magnetic pallets 30 and 32, which each have an axial magnetization with a polarity opposite to that of the magnetization axial of the periodic magnetized structure so as to generate magnetic repulsion between the magnetic pallets and the magnetized structure.
  • Each magnetized portion has a monotonically increasing width.
  • the width of the magnetized portions 38 increases, over their entire useful length, linearly as a function of the angle at the center.
  • the periodic magnetized structure 36 is arranged so that its outer periphery is circular, the magnetized arcuate portions of this magnetized structure having the same configuration and being arranged circularly around the axis of rotation of the wheel exhaust.
  • each increasing ramp of magnetic potential energy is provided so that each of the two magnetic pallets can climb it when the anchor is in a given rest position, among its two rest positions, and that a torque of force supplied to the escape wheel is substantially equal to a torque of nominal force (case of a mechanical movement equipped with a constant force system for driving the escape wheel) or included in a range of values provided to ensure normal operation of the watch movement (case of a conventional mechanical movement having a variable force torque applied to the escape wheel depending on the level of winding of the barrel or barrels if several are provided in series).
  • Increasing ramps of magnetic potential energy are climbed, when the anchor undergoes an alternating movement between its two rest positions and when the force torque supplied to the escape wheel is equal to said nominal force torque or included in the range of values provided for this force torque in normal operation, successively by each of the first and second magnetic pallets while the anchor is respectively in its first and second rest positions, and alternately by these first and second magnetic pallets during the reciprocating movement of the anchor.
  • the two magnetic paddles and the increasing ramps of magnetic potential energy are arranged so that the anchor can experience an impulse of magnetic force in the direction of its movement, after any one of the two magnetic paddles has climbed any of said ramps increasing magnetic potential energy, when the anchor swings from the rest position corresponding to any ramp of magnetic potential energy to its other rest position.
  • the periodic magnetized structure further defines for each of the two magnetic pallets magnetic barriers 46 which are located respectively following the increasing ramps of magnetic potential energy defined by the magnetized portions 38, these magnetic barriers being formed in particular by magnetic pads 46 of the structure 36, the radial dimension of which is substantially equal to or greater than the longitudinal dimension of each of the two magnets 30 and 32 forming the magnetic pallets of the anchor.
  • the magnetic barriers are not provided, the magnetized portions 38 then extending partially under the projecting parts 42 described below.
  • the escape wheel further comprises protrusions which are respectively associated with the increasing ramps of magnetic potential energy.
  • These projecting parts are formed by teeth 42 extending radially from a plate 40 which is integral with the escape wheel and located above the disc 34 carrying the magnetic structure 36. These teeth are located respectively following the magnetic portions 38, on the side of their widest end, and are partially superimposed on the corresponding magnetic pads 46.
  • the teeth and mechanical pallets are formed by a non-magnetic material.
  • the plate 40 is also formed by a non-magnetic material and it is integral with the teeth.
  • the teeth 42 extend in a general plane in which the two mechanical pallets 28, 29 of the anchor also extend.
  • the two magnets 30, 32 are respectively supported by the two mechanical pallets and are also located in said general plane.
  • the figures only show a lower magnetized structure, located below the general plane.
  • the escape wheel also comprises an upper magnetic structure, of the same configuration as the lower magnetic structure and supported by an upper disc, preferably formed of a non-magnetic material.
  • the lower and upper magnet structures together form the periodic magnet structure. They have the same magnetic polarity, opposite to that of the two magnets of the anchor, and are arranged on either side of the geometric plane in which these two magnets forming the two magnetic pallets are located, preferably at the same distance.
  • the lever 14 and the escapement wheel 16 are arranged so that, in normal operation, one of the teeth 42 of the escapement wheel undergoes at least one shock on one or the other of the two mechanical pallets after the corresponding magnetic paddle has climbed any one of the increasing ramps of magnetic potential energy following a tilting of the anchor.
  • This impact occurs in such a way as to at least partially dissipate a kinetic energy of the escape wheel acquired following said tilting.
  • the teeth of the escape wheel are designed to be able to absorb the kinetic energy of this escape wheel, at each step of the escape wheel, after an accumulation of magnetic potential energy in the escapement for a next sustain pulse of the mechanical resonator, and to thereby limit terminal oscillation during each step of its stepwise rotation.
  • a tooth 42 presses against a mechanical stop of the anchor formed by one or the other of the two mechanical pallets.
  • the escapement is therefore a hybrid escapement, that is to say magnetic and mechanical.
  • the teeth 42 and the mechanical pallets 28, 29 are arranged in such a way that, during a new winding of the barrel spring following a stoppage of the watch movement and allowing the escapement wheel 16 to start rotating again in the intended direction of rotation, at least one of the two mechanical pallets 28, 29 comes into contact with a tooth 42 of the escape wheel, which are configured so that the escape wheel can provide the anchor 14 a torque of mechanical starting force and therefore a mechanical starting impulse.
  • a tooth 42 of the escape wheel which are configured so that the escape wheel can provide the anchor 14 a torque of mechanical starting force and therefore a mechanical starting impulse.
  • each of the teeth 42 has, in a system of polar coordinates of the escapement wheel 16 which is centered on its axis of rotation, a first inclined surface which is inclined so that each of the first and second mechanical pallets 28, 29 can, in a start-up phase, slide on this first inclined surface while the escape wheel passes through a corresponding range of angular positions ⁇ .
  • a first inclined surface which is inclined so that each of the first and second mechanical pallets 28, 29 can, in a start-up phase, slide on this first inclined surface while the escape wheel passes through a corresponding range of angular positions ⁇ .
  • each of the two mechanical paddles of the anchor has, in the system of polar coordinates associated with the escapement wheel, a second inclined surface when the paddle in question is in contact with one of the teeth 42 of the escapement wheel. .
  • the second inclined surface is configured in such a way that each of the teeth 42 can, in a starting phase, slide on this second inclined surface when the escape wheel crosses a range of angular positions ⁇ which correspond
  • the connecting part, the rod and the two arms are formed by a single piece.
  • the one-piece part is made of a metallic material.
  • teeth 42 to allow one and/or the other of the two functions described previously, namely the damping of oscillations of the escape wheel during a step-by-step rotation of the latter in normal operation and/or a self-starting of the assembly formed by the mechanical resonator and the escapement, in particular an escapement of the magnetic type, has the consequence that, during a tilting of the lever 14 from a first of its two rest positions in the direction of the second rest position while the escapement wheel 16 is positioned in any angular position ⁇ of a plurality of ranges of angular positions corresponding respectively to the plurality of teeth, one of the two mechanical pallets abuts against one of these teeth before the anchor can reach the angular position for disengaging the ankle on the side of the second rest position, as shown in Figure 1B .
  • the escapement wheel 16 can stop in any angular position ⁇ d a plurality of ranges of angular positions, corresponding respectively to the plurality of teeth 42, for which one of the two mechanical pallets then abuts against one of these teeth before the anchor can reach the angular position of release of the ankle, as depicted in Figure 1B .
  • the Figure 1B shows a particularly unfavorable case where an end part 48 of the mechanical pallet 29 undergoes an impact on the top of the head 43 of a tooth 42 against which this mechanical pallet abuts.
  • the total force exerted by the lever on the tooth 42 concerned is substantially radial, in a system of polar coordinates associated with the escapement wheel, so that the escapement wheel is not driven in rotation and undergoes a major shock.
  • the radial force impulse has several components, firstly a component arising from the inertia of the moving anchor 14 which is stopped; secondly a principal component due to the mechanical energy stored in the oscillating mechanical resonator 2 which is stopped in its oscillation while its kinetic energy is almost maximum, via the coupling between the fork 18 and the pin 10; and thirdly a magnetic component arising from the fact that the shock occurs while a magnetic impulse is being supplied to the anchor (represented by an arrow at the Figure 1B ).
  • the anchor is arranged to be able to elastically absorb the energy transmitted to it by the mechanical resonator stopped in its oscillation.
  • the anchor 14 is arranged so as to be able, during a tilting during which a shock described above occurs, to bend, in a general plane of the anchor parallel to the fork 18 (this is that is to say parallel, including coincident, to a general plane in which the horns of the fork extend), by undergoing an elastic deformation under the action of a force F RO exerted by the pin 10, engaged in the fork , on one of its two horns 19a, 19b while the mechanical pallet concerned abuts against a tooth and that the mechanical resonator is braked by the anchor.
  • this anchor has an elastic capacity, between each of the two mechanical pallets 18, respectively 29 and the fork 18, allowing it to elastically absorb, during said elastic deformation, a maximum mechanical energy that the mechanical resonator 2 can have during normal operation of the watch movement.
  • this elastic capacity presents a certain margin of safety, because during the impact there is a certain dissipation of energy in particular at the level of the bearings of the escape wheel, the mechanical resonator and the anchor, and also in the various structures concerned, in particular the plate 40. Any breakage or deterioration of the escapement and of the mechanical resonator can thus be avoided.
  • 'elastic capacity' we understand an elastic energy absorption capacity. Thanks to the characteristics of the anchor according to the invention, a sudden shock is avoided and a gradual dissipation of the mechanical energy of the mechanical resonator is allowed.
  • the anchor undergoes an elastic deformation in order to be able to absorb most of the mechanical energy of the mechanical resonator, even if this mechanical energy corresponds to a nominal energy in normal operation of the watch movement.
  • the rod 20 which is arranged to be able to substantially absorb said major part of the mechanical energy of the mechanical resonator.
  • the rod is provided curved, in particular with a general shape in 'gooseneck'. Other shapes are possible, also a substantially rectilinear rod.
  • the curved configuration has an advantage in that it generally makes it possible to increase the length of the stick between the connecting part 25 and the fork 18.
  • the 'gooseneck' shape allows a relatively long length of the stick, while having the fork relatively close to one of the two mechanical paddles.
  • the person skilled in the art would connect the shortest fork with the arm 26, in the extension of the mechanical pallet 29. Thus, there would be almost no absorption of kinetic energy from the oscillating resonator.
  • a median geometric line of the anchor 14 between an end surface (terminal inclined plane) of each of the two mechanical pallets 28, 29 and the fork 18, has a total length, on the two sections 20a and 24a, respectively 20a and 26a which are defined by the mechanical pallet considered together with the corresponding arm 24 or 26 and by the rod 20 (see dashed lines at Figure 1A ), which is at least twice a length of a straight line 52 between a point on the median geometric line 24a on the end surface closest to the fork and the middle of the bottom of a cavity defined by the two horns of this fork (see Figure 1B ).
  • the elastic deformation capacity can be provided over the entire total length defined above or only over parts of this total length.
  • the rod and the arms have a capacity for elastic deformation, which may be different, whereas in a second variant, it is substantially the rod which has this elastic capacity. In a third variant, it is substantially the arms 24 and 26 which have an elastic capacity.
  • the anchor must therefore have a capacity for elastic deformation and a capacity that is large enough to absorb elastic energy, these associated capacities being a function of several parameters that those skilled in the art will be able to select and determine in order to obtain the desired values.
  • the shape can play a role, as well as the length of the material path between the mechanical paddles and the fork. Other parameters also play a role, including the selected material and the various cross-sections. It should be noted that the minimum cross-section of the anchor also plays a role, which should not be planned too small by favoring the flexibility of a portion of the anchor to the detriment of the absorption of elastic energy.
  • magnetic pulses for maintaining the oscillation of the mechanical resonator are generated at the level of the two mechanical pallets 28, 29 which respectively support two magnets 30, 32 forming two magnetic pallets.
  • the lever 14 is arranged so as to be able, during normal operation of the watch movement and therefore of the escapement, to substantially transmit a torque of magnetic force, generated by each of the magnetic pulses, to its fork to maintain a oscillation of the mechanical resonator. It will be noted that this condition can easily be implemented due to the fact that the quantity of energy in a magnetic pulse is much lower than the mechanical energy possessed by the mechanical resonator 2 in normal operation.
  • the resonator having at this moment a nominal and therefore significant mechanical energy, essentially in the form of kinetic energy, it then presses against the horn 19a by exerting a decreasing force F RO while the anchor, here especially the rod 20, bends in absorbing most of the resonator's kinetic energy as elastic energy.
  • the angle defined above therefore increases, as shown in Figure 1C where its value a2 is greater than value a1, for example approximately one value double, the Figure 1C showing a configuration as the mechanical resonator has lost most of its velocity (and therefore kinetic energy).
  • the mechanical resonator passes through an angular stop position and a premature inversion of the direction of its movement, as shown in Figure 1D where the resonator rotates counter-clockwise whereas it previously rotated clockwise.
  • the resonator recovers most of the elastic energy stored in the anchor and it thus undergoes an acceleration which leaves it with a certain amplitude of oscillation, although less than that he presented before the shock.
