Definitions

  • the invention relates to the field of mechanical watchmaking. It relates, more particularly, to a mechanism for positioning a toothed wheel mounted on an axis movable in rotation in a watch movement, said positioning mechanism comprising a positioning lever having a flat lateral edge arranged to cooperate with a flat provided on the axis of the toothed wheel.
  • the present invention also relates to a watch movement comprising such a positioning mechanism.
  • Such a positioning mechanism is for example described in the application WO 2014/076262 .
  • This prior document is incorporated by reference.
  • This mechanism comprises a positioning lever 101 having a flat lateral edge arranged to cooperate with a plate 97 provided on the pinion axis 96, 98, 100 and is used to perfectly rotate and reposition the pinions 96, 98, 100 when the Movement cycle of the information carrier is completed.
  • this mechanism does not allow fine adjustment of the positioning lever, often required in the field of watchmaking.
  • such a mechanism does not guarantee initial positioning or correct repositioning of a toothing intended to cooperate with other teeth by periods.
  • the invention particularly aims to overcome the disadvantages of the known mechanism.
  • an object of the invention is to provide a mechanism for positioning a gearwheel intended to cooperate with another gearwheel periodwise, said positioning mechanism for fine adjustment of the positioning lever to ensure initial positioning correct gear or repositioning, to ensure meshing without defects between said gears, particularly after a momentary stop of the toothed wheel.
  • the present invention relates to a mechanism for positioning a toothed wheel mounted on an axis movable in rotation in a watch movement, said positioning mechanism comprising a positioning lever having a flat lateral edge arranged to cooperate with at least one flat provided on the axis of the toothed wheel.
  • the positioning lever comprises a pivoting arm arranged to be pivotally mounted about a pivot axis provided in the watch movement, a positioning element having the flat lateral edge and articulated on the pivoting arm, and means for adjusting and locking the position of the positioning element on the pivot arm relative to the axis of the gear wheel
  • the present invention also relates to a watch movement comprising a toothed wheel mounted on an axis movable in rotation and comprising a positioning mechanism as defined above.
  • the positioning mechanism according to the invention makes it possible to ensure a very fine adjustment of the positioning lever, in order to guarantee a correct positioning or repositioning of said toothed wheel, in particular after a momentary stopping of said toothed wheel.
  • toothed wheel must be interpreted in the broad sense and denotes any circular element comprising at least one tooth sector, such as a disc, a wheel, a crown, a pinion, etc.
  • a positioning mechanism of a gearwheel 1 mounted on an axis 2 movable in rotation in a watch movement.
  • the toothed wheel 1 is arranged to cooperate with another toothing of a mechanism of the watch movement (not shown), in particular by period or cycle, the toothed wheel 1 comes to rest at the end of the period or the cycle in its position initial or any other position provided by the mechanism.
  • the toothed wheel 1 corresponds, for example, to the reversing gears 96-98 and 100 described in the application WO 2014/176262 and provided to rotate the arm actuating wheel in a clockwise and counter-clockwise direction during its travel cycle.
  • the reversing gears When the arm has carried out a movement cycle, the reversing gears must return to their original position in a certain way so that they can again mesh without flaws with the different teeth of the mechanism during the next cycle.
  • the toothed wheel 1 corresponds to the reversing gears 96-98 or 100 or any other gear wheel of a watchmaking mechanism more particularly requiring a very precise repositioning of the teeth when the cogwheel stops after pivoting d a certain angle.
  • a positioning lever 3 having a flat lateral edge 4 arranged to cooperate with a plate 6 provided on the axis 2 of the toothed wheel 4.
  • the plate 6 is made on the axis 2 so as to be positioned opposite the lateral edge 4 of the positioning lever 3 when the toothed wheel 1 stops after pivoting the determined angle.
  • the positioning lever 3 comprises a pivoting arm 8 arranged to be pivotally mounted about a pivot axis 10 provided in the watch movement.
  • the pivoting arm has, at one end, a ring 12 pivotally mounted on the pivot axis 10.
  • the pivot arm 8 carries a positioning element 14 which presents the flat lateral edge 4. More specifically, the positioning element 14 is superimposed mounted on the pivot arm 8 so as to have an outer end 14a having the flat lateral edge 4 facing the axis 2 of the toothed wheel 1 and an inner end 14b opposite the pivot axis 10 of the pivoting arm 8.
  • the positioning element 14 is hingedly mounted on the pivoting arm 8 by its outer end 14a by means of a pivot 16 provided at the free end of the pivoting arm 8 and mounted through the outer end 14a of the positioning element 14.
  • the positioning element 14 comprises between its outer end 14a and its inner end 14b a first oblong opening 18, arranged longitudinally with respect to the pivoting arm 8 and a second oblong opening 20, arranged transversely with respect to the pivoting arm 8.
  • the first and second oblong openings 18, 20 are connected by a channel 23.
  • the first opening 18 is arranged to cooperate with the means for adjusting the position of the positioning element 14 and the second opening 20 is arranged to cooperate with the means for locking the position of the positioning element 14.
  • the means for adjusting the position of the positioning element 14 on the pivoting arm 8 relative to the axis 2 of the toothed wheel 1 comprise an eccentric 22 mounted on the pivoting arm 8 and arranged to cooperate with the positioning element 14. More particularly, the eccentric 22 is mounted on the pivoting arm 8 by being housed in the first oblong opening 18 so as to cooperate with the edges of said oblong opening 18 to rotate the element positioning 14 around the pivot 16 during adjustment.
  • the means for locking the position of the positioning element 14 on the pivoting arm 8 relative to the axis 2 of the toothed wheel 1 comprise a clamping screw 24 mounted on the pivoting arm 8 and arranged to lock the positioning member 14 on said pivot arm 8. More particularly, the clamping screw 24 is mounted on the pivoting arm 8 through the second oblong opening 20 of the positioning member 14.
  • Positioning 14 can evolve around the clamping screw 24 when it is rotated for adjustment.
  • a holding spring 26 of the pivot arm As shown in figure 2 , the holding spring 26 is mounted on the pivot axis 10 and is hooked on the eccentric 22 mounted on the pivoting arm 8.
  • the operation of the positioning mechanism according to the invention is as follows: at the time of mounting the mechanism, the positioning element 14 is positioned so that its flat lateral edge 4 is aligned with the flat 6 provided on the axis 2 of the toothed wheel 1 which is opposite the positioning element 14 when the toothed wheel 1 is in a position corresponding to its stopped position after pivoting the determined angle.
  • the positioning element 14 presses the plate 6 in order to properly reposition the toothed wheel 1 so that its toothing can mesh without flaws with the mechanism associated with the next restart of the toothed wheel 1.
  • the positioning element 14 is pivoted about the pivot 16 by means of the eccentric 22 cooperating with the edges of the first oblong opening 18 so as to modify more or less the angular position a of the positioning element 14 with respect to the positioning arm 8, as shown in the Figures 3 and 4 .
  • the second oblong opening 20 allows the displacement of the positioning element 14, while leaving the adjustment screw mounted on the pivot arm.
  • the positioning lever 3 is raised by the rounded face of the axis 2 of the toothed wheel 1.
  • the flat 6 arrives opposite the pivoting lever 3 which is lowered, brought back by its holding spring 26.
  • the flat lateral edge 4 of the pivoting element 14 presses on the flat 6 of the axis 2 to reposition the toothing of the toothed wheel 1, as shown in figure 6 .
