Definitions

  • the present invention relates to a movement for a timepiece of the type comprising a finishing gear, a vortex and a frame defining a reference plane, the mobiles of the work train and the swirling vortex on the frame about perpendicular axes. to the reference plane.
  • the tourbillon is a device designed to average walking in vertical positions. It comprises a cage on which are mounted pivoting a balance spring and an escapement mobile comprising a wheel and a pinion.
  • a fixed wheel is disposed on the frame so as to cooperate with the pinion to drive the mobile escape, when the cage rotates.
  • the latter comprises a pinion or a wheel, hereinafter referred to as a cage gear, kinematically connected to the finishing gear of the timepiece, generally to the average wheel.
  • the motions of the movement are, in general, arranged and numbered so that the tourbillon performs one revolution per minute.
  • the position of the point of attachment of the balance is one revolution per minute, which averages the deviations in the vertical positions.
  • An example of this type of vortex is given by the document WO 01/59529 .
  • the German watchmaker Walter Prendel made a pocket watch in which the axis of the balance is at an angle of 30 ° with that of the tourbillon cage and those of the other mobiles of the watch arranged on the frame. In this way, the position of the pendulum varies from 30 to 60 ° maximum when the watch is in the vertical or horizontal position.
  • the components of the exhaust are also inclined, the inclination angle increasing from the escape wheel to the balance. Such a solution is difficult to control from the technical point of view and the working conditions of the exhaust are unfavorable.
  • the timepiece movement according to the invention comprises a frame defining a reference plane, a finishing gear, a fixed wheel and a vortex comprising a cage which rotates about an axis AA and on which are pivotally mounted a sprung balance and an escapement comprising a wheel and a pinion.
  • This movement is characterized in that the rocker and the escape wheel pivot respectively about axes BB and CC parallel to each other and which are at an angle to the axis of pivoting of the cage.
  • the cage is advantageously pivotally mounted on the frame, while the fixed wheel, provided with teeth having flanks, mounted rigidly on the frame, is arranged to cooperate with the pinion of the exhaust mobile to drive it when the cage turns.
  • the fixed wheel and the pinion of the escapement wheel are arranged so as to form a gear in which the flanks of their teeth, in their contact zone, are tangent to each other. the other.
  • the fixed wheel and the exhaust pinion together form a conical gear.
  • the axis of the escapement does not intersect the axis of the cage and is tangent to a cylinder whose radius is substantially equal to the distance between the balance and the mobile escape, it is possible to obtain good meshing conditions with an escape pinion and a fixed wheel together forming a helical gear.
  • the cage comprises two planks defining planes parallel to each other and oblique with reference to its pivot axis, the pivoting axes of the balance wheel and the escapement wheel being perpendicular to the planes of the two planks.
  • the escapement comprises, in addition, an anchor. Its pivot axis is parallel to that of the balance and the mobile escape.
  • the vortex 16 comprises a cage 20 comprising two boards 22 and 24 interconnected by pillars not visible in the drawing, two shafts 26 and 28, respectively mounted on the boards 22 and 24 and each provided with a pivot, identified by the letter a , at their free end, engaged in one of the bearings 14.
  • the shafts are fixed on the boards by screws schematically represented by centerlines. It is clear that the boards 22 and 24 are very strongly cut, so that the cage 20 is as light as possible.
  • the contact surfaces of the shafts against the boards are at an angle to the axis AA, so that the boards 22 and 24 are oblique with respect to this axis.
  • the shaft 26 is further provided with a pinion 26b meshing with the average wheel 18.
  • the boards 22 and 24 are each provided, in their central part, with a housing in which a kitten 27 is driven.
  • a spiral balance 29 is pivotally mounted in these kittens 27, around an axis BB perpendicular to the boards and inclined. an angle ⁇ relative to the axis AA, typically between 20 and 45 °.
  • Axes AA and BB intersect in the space between the two boards. In this way, the balance may have a large diameter, despite the fact that it is inclined relative to the reference plane.
  • the board 22 carries, in addition, a bridge 30. Stones 32 are fixed one in the bridge 30, the other in the board 22.
  • An escape wheel 34 comprising a pinion 34a and a wheel 34b, y is pivoted.
  • the pinion 34a is arranged to mesh with the fixed wheel 19.
  • the escapement wheel pivots about an axis CC parallel to the axis BB. In this figure, the escape wheel is arranged so that it intersects the axis AA, thus describing a cone whose apex is on the axis AA and which forms an angle equal to 2 ⁇ .
  • the escapement with which the tourbillon is equipped is frequently of Swiss anchor type.
  • the rocker 29 is kinematically connected to the escapement wheel 34 by an anchor which converts the rotary movement of the wheel in reciprocating motion.
  • the anchor was not represented on the drawing to avoid overloading it. It pivots between two stones carried one by the board 24, the other by an additional bridge not visible in the drawing, about an axis parallel to the axes BB and CC.
  • the structure of the fixed wheel 19 depends on the position and orientation of the mobile 34 on the cage. If its DC axis intersects the AA axis, as shown on the figure 1 it is advantageous that the fixed wheel 19 and the pinion 34a together form a bevel gear.
  • the taper can be entirely defined on the pinion, on the wheel or distributed between the two.
  • this gear is advantageously helical type.
  • the gear formed by the pinion 34a and the fixed wheel 19 then has a complex structure between these two cases.
  • the average wheel 18 and the gear 26b are advantageously numbered so that the vortex makes one revolution per minute.
  • the rocker 29 will describe a cone and will permanently an angle ⁇ relative to the vertical. If it is in a vertical position, the angle of the axis BB with respect to the vertical is between 90 ° + ⁇ and 90 ° - ⁇ . More generally, whatever the position of the timepiece, never the axis of the balance remains in a fixed position. In this way, walking is better averaged. Moreover, the structure of the constituent parts remains relatively simple, only the shafts 24 and 26 having left faces. Moreover, the meshing conditions of pinion 34a and working anchor with the escape wheel remain quite normal and quality.
  • the vortex could not be of the flying type, that is to say with a single pivot point, or of a type comprising several cages, for example as described in the document WO03017009 .
  • the taper of the gear formed by the wheel 19 and the pinion 34a is entirely made on the wheel 19. It would also be possible to have a pinion 34a conical or to distribute the taper between the two components of the gear.
  • the two embodiments described comprise a cage disposed perpendicularly to the reference plane of the movement. It is also possible to tilt the AA axis so that it is not perpendicular to the reference plane. In this case, the teeth of the average wheel 18 and the gear 26b are cut so as to form together a bevel gear.
  • the movement according to the invention has remarkable advantages, without posing industrially insurmountable technical problems.
