Definitions

  • the present invention relates to an escapement mechanism of a watch movement, in particular an escapement of Swiss anchor or anchor type.
  • the invention relates more particularly to the optimization of the assembly constituted by the plate pin and the fork of the anchor.
  • the assembly constituted by the anchor plate and the fork of the anchor allows the release of the anchor of a tooth of the wheel of the escape mechanism and the pulse of the balance.
  • the plate pin which is connected to the balance, and the fork of the anchor, allow the transmission of energy from the anchor to the balance at each alternation.
  • a conventional system consists of a so-called "half moon” circular ankle with a portion of the circle that is removed to allow the ankle to enter the fork with sufficient security.
  • the fork is in the form of a rectangular notch.
  • the contact surfaces with the ankle are generally flat.
  • the surfaces in contact between the fork and the peg are identical for the clearance and for the impulse, namely, the pair of surfaces in contact during the release of the first alternation is identical to the pair of surfaces in contact during the impulse of the second alternation.
  • a geometry that would be optimized for the release function might not be optimized for the pulse function.
  • the geometry of the ankle and fork assembly is therefore not optimized.
  • the optimization of the geometry of the contact surfaces between the ankle and the fork is aimed at in particular to reduce the friction in order to reduce the wear of the parts, or to reduce the energy losses to increase the efficiency of the exhaust.
  • An object of the invention is to provide a precise and reliable watch exhaust mechanism over a long period of use.
  • a watch exhaust mechanism for a watch movement comprises an anchor with a fork and a tray device with a peg coupled to a rocker, the fork comprising a first horn and a second horn.
  • the peg includes a first cam portion configured to engage the first horn, and a second cam portion configured to engage the second horn.
  • the first cam portion includes a first cam surface configured to engage the first horn at a first level of the ankle
  • the second cam portion includes a second cam surface configured to engage the second horn at a second level of the ankle.
  • the first and second levels are offset in a direction parallel to the axis of rotation (A) of the tray device.
  • the first horn in a direction of rotation of the balance the first horn functions as the input horn and the second horn as the output horn, and in the opposite direction the first horn functions as a horn exit and the second horn as the input horn.
  • the invention also extends to escape mechanisms having a single clearance and pulse per cycle of round-trip of the balance, and in this case one of the horns functions only as an input horn and the other only as an output horn.
  • the first cam surface of the first cam portion may advantageously have a different and non-symmetrical geometric profile of said second cam surface of the second cam portion. This makes it possible to optimize the geometric profiles of the surfaces for the release and impulse functions in order to eliminate or minimize the friction between the ankle and the fork
  • the first cam part further comprises a second cam surface configured to engage the first horn at said second level
  • the second cam portion further comprises a first cam surface configured to engage the second horn at said first level.
  • the engagement surfaces of the fork contacting the ankle may also be symmetrical with respect to a median plane of the range.
  • the second cam surface of the first cam portion may also advantageously have a different and non-symmetrical geometric profile of said first cam surface of the second cam portion for the reasons mentioned above.
  • the cam surfaces on one side of the peg may be symmetrical to the cam surfaces on the other side of the peg so as to have an identical engagement between the peg and the fork in both directions of rotation of the peg.
  • the first horn includes a first engagement surface configured to engage the first cam surface of the first cam portion, and the second horn comprises a second engagement surface configured to engage the second surface of the first cam surface; cam of the second cam portion, said first engagement surface having a different and non-symmetrical geometric profile of said second engagement surface.
  • the first horn may also include a second engagement surface configured to engage the second cam surface of the first cam portion, and the second horn may include a first engagement surface configured to engage the first cam surface of the second cam portion, said second engagement surface having a different and non-symmetrical geometric profile of said first engagement surface.
  • the first and second levels can advantageously be separated by a space, either on the ankle, or on the fork, or on both, in order to increase the assembly tolerances and to avoid interference between a level on the ankle and the other level on the fork.
  • the cam surfaces and engagement surfaces are configured so that one of the levels operates at least in part a release function of a first pallet of the anchor, and the other of the levels operates at least in part a pulse function of a second pallet of the anchor.
  • the level operating a release function can further operate a pulse function on the second pallet of the anchor, subsequent to the pulse function operated by the other level.
  • the other level operating a pulse function can also operate a release function on the first pallet of the anchor, subsequent to the release function operated by said level operating a release function. This offers more possibilities for optimizing the geometric profiles of the surfaces coming into contact during the clearance and impulse operations.
  • the fork and the peg may advantageously be made by a deposition process such as by photolithography, or by other manufacturing processes used in the semiconductor industry, of a silicon-based material.
  • a silicon-based material for example silicon carbide or silicon nitride
  • nickel for example nickel, nickel phosphorus
  • the peg comprises at one of the levels a substantially elliptical shape, this level serving mainly for the pulse function.
  • the ankle may comprise at the other level a conventional shape, such as a half-moon shape, or other profiles according to the optimization calculations.
  • the reduction ratio between the anchor and the rocker defined by the ankle and the fork at the first level may advantageously be different from the reduction ratio defined by the ankle and the range at the second level.
  • the clearance reduction ratio is defined by the ratio of the rotation radius of the point of contact of the ankle at the first level divided by the radius of rotation of the point of contact of the fork at the first level.
  • the pulse reduction ratio is defined by the ratio of the radius of the contact point of the ankle to the second level divided by the radius of rotation of the point of contact of the range to the second level.
  • the clearance reduction ratio may advantageously be smaller than the pulse reduction ratio. This configuration makes it possible to minimize the torque taken on the balance during disengagement.
  • the use of a structure fork / ankle organized according to two levels makes it possible to have a first level dimensioned and optimized to achieve the function of clearance (first and / or second alternation of the oscillation) while the second level can be sized and optimized to achieve the pulse function.
  • an escape mechanism for a watch movement comprises a wheel 5 with teeth 9, an anchor 7, and a plate device 4 coupled to a rocker 2.
  • the anchor includes a fork 13, vanes 17a, 17b, and a rod 15 interconnecting the vanes with the fork.
  • the wand is rotatably coupled to the frame by a pivot 11.
  • the vanes engage the teeth 9 of the wheel which is connected to a power source providing a rotational torque on the wheel.
  • One pallet forms the entry pallet 17a and the other constitutes the exit pallet 17b.
  • the anchor further comprises a dart (not shown) attached to the fork by means for example of a shaft driven into a fixing hole 27 at the base of the fork.
  • the illustrated mechanism corresponds to an escapement of Swiss anchor type. As this principle is well known, the conventional elements and their operation will not be described in more detail here.
  • the tray device 4 comprises a large plate 6 with an anchor 10 and a small plate 8 provided with a notch 16 for the passage of the stinger.
  • the pin 10 comprises on one side a first cam portion 12 and on the other side a second cam portion 14.
  • the first cam portion 12 functions as the input cam and the second cam portion as the output cam.
  • the rocker having an oscillating movement, in the other direction of rotation (second alternation), the functions of the first and second cam parts are reversed.
  • the fork 13 comprises a first horn 19 and a second horn 21.
  • first alternation the first horn 19 functions as horn of entry and the second horn like horn of exit.
  • second alternation the functions of the first and second horns are reversed.
  • the pin 10 comprises two levels 10a, 10b, these levels being offset relative to each other in a direction parallel to the axis of rotation (A) of the pivot 11.
  • the fork 13, which is engaged by the ankle at each alternation, also comprises two levels corresponding to the levels 13a, 13b.
  • the peg includes first cam surfaces 12a, 14a at a first level 10a, and second cam surfaces 12b, 14b at a second level 10b.
  • the horns 19, 21 comprise first engagement surfaces 23a, 25a at the first level 13a and second cam surfaces 23b at the second level 13b.
  • the two levels of the ankle may be spaced a height h to avoid contact between the different levels of the fork and the ankle.
  • the two levels are interconnected by an interconnection piece 10c integral with the two levels.
  • this space can also be introduced on the fork, in addition to or instead of being on the ankle.
  • the cam and engagement surfaces may advantageously have distinct profile geometries for the fork / peg contact during the release and pulse functions.
  • one of the levels is dedicated to the release function (according to the illustrated example, the first level 10a, 13a) and the other level is dedicated to the pulse function (according to the illustrated example, the second level 10b, 13b).
  • the first levels 10a, 13a of the fork and the peg cooperate ( figure 3a ).
  • the first cam surface 12a comes into contact with the first engagement surface 23a of the first horn 19.
  • the anchor 7 is pushed by the rocker 7, which therefore loses some of its energy.
  • the contact between the two profiles takes place at a certain angle, greater than the angle necessary for the release of the anchor pallet 17a of the tooth 9 of the escapement wheel 5 because of the geometric and dynamic recoil of the gear train and the finite acceleration of the cog wheels.
  • the anchor is pushed by the rocker 7 only, while, from the end of the release, the anchor is pushed by the rocker 7 and the escape wheel 5, the speed of the latter is not still sufficient to cause the loss of contact between the surfaces 23a and 12a.
  • This contact occurs for the majority of the time of the pulse function.
  • the fork-pinch contact takes place on the second level 10b, 13b.
  • This case corresponds to a construction providing a pulse plane Pr of the escape wheel much shorter than the pulse plane Pa of the pallet of anchor: Pr ⁇ Pa / 3 .
  • the pulse ends early compared to the entry at the end of the range.
  • the fork-pinch contact passes on the first level 10a, 13a ( figure 2 and 3c ).
  • This case corresponds to a construction providing a pulse plane Pr of the escape wheel comparable to or greater than the pulse plane Pa of the anchor pallet: Pr ⁇ Pa / 3 .
  • the pulse ends immediately before the abutment of the range.
  • the reduction ratio between the anchor and the beam defined by the pin 10a and the fork 13a at the first level differs from the reduction ratio defined by the pin 10b and the fork 13b at the second level.
  • the reduction ratio of a level is function of the radius of rotation ( r 10a , r 10b ) of the point of contact on the pin and the radius of rotation of the point of contact on the fork ( r 13a , r 13b ), the reduction ratio being the radius of the point of contact of the ankle divided by the radius of the point of contact of the fork.
  • radius of rotation of a point of contact on the ankle, respectively on the fork means the distance between the axis of rotation of the ankle, respectively of the fork, and the point of contact between the ankle and the fork.
  • the clearance reduction ratio defined by the ratio of the radius of rotation of the point of contact of the first level 10a of the ankle divided by the radius of rotation of the point of contact of the first level of the fork 13a
  • the pulse reduction ratio defined by the ratio of the radius of rotation of the contact point of the pin 10b divided by the radius of rotation of the point of contact of the fork 13b.
  • This configuration advantageously makes it possible to minimize the torque taken on the balance during disengagement.
  • the invention can also be used in natural coaxial type exhausts, with English type anchors or else other escapements of known types.
  • the fork and / or the ankle can be made of different materials including Silicon, Silicon Nitride, and Silicon Carbide, by various manufacturing processes including deposition, photolithography, and DRIE (Deep reactive-ion etching) processes. .
