Definitions

  • the present invention relates to a timepiece movement comprising a mechanism and a barrel provided for driving the mechanism via a kinematic link arranged to exert a driving torque on the mechanism, the barrel comprising a drum and a motor spring arranged in the drum so as to exert on the mechanism a motor torque which varies according to the degree of winding of the motor spring.
  • the watch movement also comprises an equalization device kinematically connected to the barrel so as to be able to be driven by this barrel and to be able to exert an auxiliary torque which is added to said driving torque to form together said driving torque.
  • the auxiliary torque is designed to vary as a function of the degree of winding of the mainspring so as to oppose variations in the engine torque, and thus to substantially equalize the drive torque.
  • Watchmaking movements are already known which include an equalization device and which correspond to the above definition, in particular devices with rockets used to compensate for the variation in the torque supplied by a barrel.
  • a particular watch movement equipped with a rocket device is disclosed in the document EP 2,735,919 A1 .
  • This watch movement is particular in that the rocket here is substantially planar, this rocket being produced by a spiral groove engraved in a disc.
  • a wire is stretched between the barrel and the rocket, a fixed guide provided with a winding roller used to make the wire penetrate into the groove starting from the outside of the disc in the direction of its center.
  • An object of the present invention is to remedy the aforementioned drawbacks of the prior art.
  • the invention achieves this object by providing a timepiece movement according to claim 1 appended hereto.
  • the formulation according to which the variation of the auxiliary torque is opposed to the variation of the motor torque, in a useful range of the degree of winding of the mainspring, amounts to saying that the derivative of the auxiliary torque compared to the degree of winding is of opposite sign to the derivative of the motor torque with respect to the degree of winding. It also follows that the derivative of the auxiliary torque with respect to time is of opposite sign to the derivative of the engine torque with respect to time.
  • the equalization device comprises a first magnetic element and a second magnetic element which are arranged so as to exert on each other a variable magnetic force as a function of their relative position, respectively of the degree of winding of the mainspring.
  • the auxiliary torque produced by the equalization device is generated by this variable magnetic force.
  • at least one of said first and second magnetic elements comprises a permanent magnet.
  • these two magnetic elements are formed respectively by a bipolar permanent magnet and a cam made of material with high magnetic permeability.
  • a magnetic element including at least one physical parameter (radial / lateral or axial as the case may be), active in the magnetic interaction considered between the cam and another magnetic element with which it is associated, varies so as to generate with this other magnetic element a magnetic force between them, in the direction of a relative movement between the cam and the other magnetic element, the intensity of which varies as a function of this relative movement.
  • the physical parameter in question may be a parameter specific to the cam, for example the intensity of a magnetic flux supplied by a magnetized material forming the cam, or relative to the other magnetic element, in particular the distance between them.
  • the equalization device has several advantages. In particular, it forms a contactless system so that the variable auxiliary torque it provides is generated without friction. Furthermore, it is known that the magnetic forces which are caused by permanent magnets are conservative forces which derive from a magnetic potential. Thus, the auxiliary torque supplied by the equalization device also derives from a magnetic potential, so that the energy dissipated by the equalization device of the invention during a complete winding cycle - disarming of the mainspring can theoretically be zero. We will thus easily appreciate the advantage conferred by such an equalization device if we keep in mind that, especially in a device of the 'stackfreed' type, the energy supplied for the auxiliary torque is completely dissipated.
  • the Figures 1A and 1B respectively illustrate two alternative arrangements of the magnetic system, formed of first and second magnetic elements, of an equalization device according to the invention.
  • the first and second magnetic elements are respectively a magnetic cam and a bipolar magnet.
  • the cam is flat and it is made of a magnetic material (for example NdFeB, SmCo or PtCo to form a second permanent magnet or by a ferromagnetic material).
  • the cam 3A, respectively 3B is arranged to rotate about an axis 5 which is perpendicular to the general plane of the cam.
  • the bipolar magnet is mounted here fixed opposite the cam, with its North-South axis oriented substantially in the direction of the axis of rotation 5.
  • the bipolar magnet 7 is arranged in the same plane as the cam 3A, respectively 3B.
  • the cam is formed either by a magnet with a substantially radial magnetization, in the same direction as that of the bipolar magnet so that the magnetic interaction is in attraction, either by a material with high magnetic permeability which also generates a magnetic interaction in attraction with the bipolar magnet.
  • the shape of the cam 3A, respectively 3B is in a spiral shape, the contour opposite the fixed bipolar magnet (external contour also called 'edge' below) of this cam being in a spiral (this is i.e.
  • the two configurations illustrated schematically in the Figures 1A and 1B are distinguished by the direction of inclination of the edge of the cam, in other words by the direction of the spiral defined by this edge. Indeed, we can see that in the figure 1A , the distance between the edge of the cam 3A and the magnet 7 gradually increases when it rotates counterclockwise, while in the figure 1B conversely, the distance between the edge of the cam 3B and the magnet 7 gradually decreases when the cam is rotated counterclockwise also. Then, the magnetic attraction force varies in intensity. Referring first to the figure 1A , it can be seen that the distance between the edge of the cam and the magnet increases progressively during the aforementioned rotation.
  • the increase in distance is accompanied by a concomitant decrease in the intensity of the tangential magnetic force exerted on the cam 3A by the magnet 7.
  • a variation in complementary intensity can be generated by an angular variation in the intensity of the magnetic flux generated by the cam. This increases the tangential / angular magnetic force which generates the auxiliary torque of the equalization device.
  • the decrease in the distance between the magnet and the cam is accompanied by a concomitant increase in the intensity of the magnetic force.
  • the figure 1A further shows that the tangential component Ft of the magnetic force is opposite to the direction of rotation of the cam 3A. Conversely, in the figure 1B , the orientation of the tangential component corresponds to the direction of rotation of the cam 3B.
  • the configuration of the figure 1A generates a force which opposes the rotation of the cam and whose intensity decreases with rotation
  • the configuration of the figure 1B generates a force which is combined with the rotation of the cam and whose intensity increases with rotation.
  • the configuration of the figure 1A generates a torque in the opposite direction to that of the rotation of the cam
  • the configuration of the figure 1B generates a torque in the same direction as that of the rotation of the cam.
  • the arrangement of the magnetic equalization device does not necessarily include a radial type magnetic system, as illustrated in the Figures 1A and 1B .
  • the arrangement of the cam-magnet assembly can form a magnetic system of the axial type.
  • the second magnetic element (the bipolar magnet) is not arranged in the same plane as the cam, but above or below this cam, so that the magnetic interaction between the magnet and the cam generates a force, the result of which has a main component which is parallel to the axis of rotation of this last.
  • an arrangement of the radial type or of the axial type is not always accompanied by a radial, respectively axial magnetization of the elements of the magnetic assembly.
  • the magnetization axis of the cam when the latter is formed by a magnet, can be axial. The same goes for the magnet associated with the cam.
  • the figure 2 is a partial plan view of a watch movement according to a first particular embodiment of the invention.
  • the partial view only illustrates the components of the movement which are essential for understanding the invention.
  • the other components, in particular the gear train and the winding mechanism may be conventional and are not illustrated.
  • the movement illustrated in the figure 2 comprises a barrel 11 which comprises a pinion 13 mounted on the barrel shaft.
  • the pinion 13 rotates clockwise when the barrel spring (not shown) disarms by driving at least one movement mechanism.
  • the pinion 13 drives an auxiliary reduction gear train comprising first of all a first mobile formed by a wheel 15 and a pinion 17.
  • the wheel 15 is arranged to mesh with the pinion 13 of the barrel, and the pinion 17 is arranged to mesh with a wheel 19.
  • the wheel 19 carries a bipolar magnet 107 mounted on its board in an eccentric position with a radial magnetic orientation.
  • a magnetic spiral cam 103 is fixedly arranged opposite the wheel 19, concentrically with the latter.
  • the stops 21 and 23 are preferably made of a non-magnetic material and are arranged in on either side of the discontinuity 22 of the edge of the cam so that the magnet 107 never passes opposite this discontinuity.
  • the gear ratio of the gear train which has just been described is a function of the number of turns that the barrel performs between its fully armed state and its completely disarmed state. Indeed, this ratio must be greater than the number of revolutions of the barrel so that the pivot angle of the magnet 107, which is integral with the wheel 19, is always less than 360 °. In other words, it is provided that the wheel 19, carrying the first magnetic element or the second magnetic element, performs less than one turn when the barrel makes several turns between its fully armed state and its completely disarmed state. In the example illustrated, the barrel shaft makes seven turns to change the barrel spring from the fully cocked state to the fully disarmed state, or vice versa. On the other hand, the transmission ratio of the gear train is 8.4.
  • the wheel 19 makes a little less than 5/6 of a clockwise rotation during the running of the watch.
  • the two stops 21 and 23 which determine the two extreme angular positions of the wheel 19 by stopping the magnet 107 when it reaches one or the other of the ends of its travel.
  • the wheel 19 rotates in the same direction as the barrel pinion 13. Under these conditions, the wheel 19 and the magnet 107 rotate clockwise when the barrel spring (not shown) disarms by causing movement. As the variable radius of the cam 103 increases counterclockwise, there is a tangential component Ft of the magnetic attraction force between the magnet 107 and the cam 103, which acts on the movable magnet 107 in the counterclockwise direction . Thus, when the barrel spring discharges and the wheel 19 therefore rotates clockwise, a magnetic force opposes this rotation. In addition, the intensity of the magnetic force decreases as the spring disarms.
  • the equalization device which has just been described provides an auxiliary magnetic torque which is opposite to the engine torque and the magnitude of which decreases in parallel with the magnitude of the engine torque when the barrel spring disarms.
  • the equalization device could just as easily provide an auxiliary magnetic torque which reinforces the engine torque, and the magnitude of which increases as that of the engine torque decreases when the barrel spring disarms.
  • the timepiece movement barrel is arranged to drive a timepiece mechanism by means of a kinematic link providing engine torque to the mechanism.
  • the kinematic link arranged to drive the watch mechanism generally comprises a multiplier train (for example, the driven watch mechanism is a Swiss lever escapement and the multiplier train forms the finishing train of the watch movement).
  • the gear train (not shown) is driven directly by the barrel pinion 13. In this case, it will be said that the gear train is arranged in parallel with the equalization device (as with a 'stackfreed 'classic).
  • a mechanism is driven by the barrel via the equalization device. In this case, at least part of the auxiliary train of the equalization device forms the kinematic connection between the barrel and the mechanism.
  • the drum of the barrel 11 does not have any external toothing. This is what which is called a smooth barrel.
  • the present invention requires that the equalization device be wedged angularly on the barrel.
  • the two limit angles, defined by the stops 21 and 23 for the angular travel of the wheel 19, must correspond to the states of "fully armed” and “completely disarmed” of the barrel spring, respectively.
  • the bipolar magnet is fixed relative to the barrel support (plate)
  • the mechanism drive and the reassembly of the barrel are both exerted via the barrel pinion 13, which is also coupled to the equalization device.
  • the winding can be carried out by means of a winding crown and / or an oscillating weight.
  • the winding mechanism can drive either directly with the barrel pinion 13, or with another gear element downstream of the barrel pinion.
  • the bipolar magnet is integral in rotation with the barrel shaft, the reassembly and disarming of the barrel can be carried out respectively via the shaft and the barrel drum, or vice versa.
  • the equalization device which has just been described can be used jointly with a device for indicating the power reserve.
  • a needle is mounted on an axis of the wheel 19.
  • a lever is associated with the cam 103. This lever defines a cam follower and is arranged to bear against the lateral surface of the cam 103.
  • the power reserve indicator may be integral with the lever or be formed by a separate member actuated by this lever.
  • Partial views of figures 3 to 5 illustrate a second embodiment of the invention corresponding to a minute repeater watch movement.
  • the minute repeater is a striking mechanism that is driven by a dedicated barrel.
  • the striking mechanism works thanks to hammers which, when activated, strike the stamp springs repeatedly.
  • a peculiarity of this kind of mechanism is that the speed at which the bell is executed depends on the magnitude of the drive torque received from the barrel.
  • a barrel (generally referenced 111).
  • the barrel shown is formed by a barrel drum 131 which serves as a housing for a spring 133, a barrel cover 135 (shown in the figure 5 ) which closes the box formed by the drum, and a barrel shaft 137 which passes through the barrel and which is pivoted at its ends between the plate and a bridge (not shown).
  • the barrel shaft 137 is integral with a toothed mobile comprising a pinion 113 and a wheel 139.
  • the figures 3 and 4 still show a winding rake 141 and a one-way train 143.
  • One-way trains are devices known as such.
  • the gear train 143 comprises an input wheel 145 which meshes with the rake 141 and an output wheel 147 (visible in the figure 3 ) which meshes with the barrel pinion 113.
  • the toothed wheels 145 and 147 are coaxial and can pivot relative to each other.
  • One of these two wheels carries a coaxial ratchet (not shown) which is sandwiched between the input wheel and the output wheel.
  • a pawl (not shown) is pivoted on the wheel plank which faces the ratchet.
  • This ratchet is recalled against the periphery of the ratchet by a spring (not shown).
  • the pawl is arranged to cooperate with a tooth of the ratchet when the input wheel rotates counterclockwise and to slide against the ratchet when the input wheel rotates clockwise.
  • the barrel 111 is arranged to drive the striking gear (not shown) via the toothing of the wheel 139.
  • the wheel 139 is integral with the barrel shaft 137. It will be understood that when the spring barrel gradually disarms, the barrel shaft drives the wheel 139 counterclockwise by transmitting to it a variable motor torque depending on the degree of winding of the barrel spring. In addition, as the torque which drives the striking mechanism is variable depending on the degree of winding of the barrel, the speed at which the striking is carried out also depends on the degree of winding of the barrel spring. It will be noted that the wheel 139 performs less than one revolution between its fully armed state and its completely disarmed state.
  • the magnet 207 is arranged on the wheel 139 so that it does not cross the discontinuity of the edge of the cam when the barrel disarms between the two aforementioned extreme states.
  • the barrel is reassembled using the rake 141.
  • the wearer of the watch can actuate the rake manually using a pusher (not shown) or a lock (not shown) which is located on the watch case.
  • the watch wearer actuates the rake, the latter rotates by driving the input wheel 145 of the one-way gear 143 counterclockwise.
  • the output wheel of the one-way train is driven by the input wheel and it itself drives the barrel pinion 113 which thus makes a little less than one turn clockwise, causing the winding of the spring. barrel 133.
  • a spring recalls the rake in the opposite direction to that of the arrow on the figure 4 .
  • the rake return stroke has the effect of driving the input wheel 145 of the one-way train clockwise. Since the one-way train does not transmit clockwise rotation, the barrel shaft is not driven in the opposite direction.
  • the figure 5 is a partial perspective view from below of the second embodiment which is also the subject of figures 3 and 4 .
  • some parts, including the rake and the wheel 139, have been omitted so as to reveal the two magnetic elements of the equalization device according to the invention.
  • these two magnetic elements are respectively a magnetic cam 203 and a bipolar cylindrical magnet 207.
  • the cam 203 is arranged concentrically with the barrel shaft and it is fixed to the barrel cover 135.
  • the bipolar magnet 207 for its part, is mounted on the plate of the wheel 139 at a distance from the axis of rotation to be arranged opposite the cam.
  • the magnet preferably has an axial magnetization direction (parallel to the axis of rotation of the barrel). It will be understood that, under these conditions, the magnetic interaction between the magnet and the cam has a main direction which is essentially axial. It will therefore be said that the arrangement of the equalization device is here of the axial type, which has the advantage of being generally more compact than a device of the radial type.
  • the magnet 207 which is integral with the wheel 139, rotates in the same direction as the barrel shaft 137. Under these conditions, the magnet 207 rotates in the counterclockwise relative to the cam when the barrel spring 133 disarms causing the bell to ring. As the figure 5 , the radial width of the cam 203 increases as it travels counterclockwise. Under these conditions, the intensity of the magnetic interaction between the magnet and the cam increases with the disarming of the barrel spring. The resulting magnetic potential generates a tangential force on the magnet.
  • the equalization device which has just been described provides an auxiliary torque which is exerted on the barrel shaft in the same direction as the engine torque and which increases as the engine torque decreases.
