Definitions

  • the invention relates to a pivoting assembly for a timepiece and, more particularly, to a timepiece wheel or resonator.
  • EP 2 743 781 and CH 699 680 disclose an organ resiliently blocked on an axis by a washer. Such a configuration makes it possible to avoid adjusting the shell of a hairspring or a wheel on an axis and then being glued at its points of contact.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a pivoting assembly using an elastic washer described in the documents EP 2,743 781 and CH 699680 which has a total thickness allowing its application to any type of watch movement.
  • the invention relates to a pivoting assembly comprising a shaft rotatably mounted between two bearings, a member mounted on the shaft with the aid of at least one spring washer characterized in that at least one of the two bearings comprises a limit stop which is arranged to come into direct contact with the at least one elastic washer to restrict the relative displacement between the axis and the two bearings.
  • the invention relates to a timepiece comprising at least one pivoting assembly according to one of the preceding variants.
  • the documents EP 2 743 781 and CH 699 680 respectively disclose a hairspring and an organ resiliently locked between the bearing of an axis and a washer. Such a configuration is presented to the figure 1 .
  • a regulating member 1 formed of an axis 2 mounted between a bridge 3 and a plate 4.
  • the regulating member 1 comprises a spiral 5 and a rocker 6 which are mounted between a bearing of the axis 2 and a washer elastic 7.
  • the axis 2 further comprises two bearing surfaces 8, 8 'each intended to come into contact with a bearing 9, 9' mounted respectively in the bridge 3 and the plate 4. It is immediate that the configurations described in the documents EP 2 743 781 and CH 699 680 impose a non-negligible distance between the washer 7 and the bearing 9 which can prevent their implementation in a thin movement.
  • the invention relates to a pivoting assembly comprising an axis rotatably mounted between two bearings and a member mounted on the shaft with the aid of at least one spring washer.
  • at least one of the two bearings comprises a limiting abutment which is arranged to come into direct contact with said at least one spring washer in order to restrict the relative displacement between the axis and its bearings.
  • an axis may also comprise at least two washers, either attaching a single member or each washer attaching a separate member against a range distinct from the axis.
  • this allows each of the two bearings can come into direct contact with one of the washers used on the axis in order to restrict the relative displacement between the axis and its bearings while limiting as much as possible the height of the pivoting assembly.
  • the figure 2 relates to a first embodiment forming a pivoting assembly of the gear type.
  • the pivoting assembly 11 comprises an axis 12 rotatably mounted between two bearings 13 and 14 respectively mounted in a plate 15 and a bridge 16.
  • each bearing 13, 14 comprises a bearing 17, 18 arranged to receive a pivot 19, 20 formed on each end of the axis 12.
  • a member forming a wheel 21 is mounted between a bearing surface of the shaft 12 and an elastic washer 22. It can also be seen that the shaft 12 comprises a pinion 23 under the wheel 21.
  • at least one two bearings 13, 14 comprises a limit stop 25 which is arranged to come into direct contact with the spring washer 22 in order to restrict the relative displacement between the axis 12 and its bearings 13, 14.
  • the second embodiment illustrated in Figures 3 and 4 illustrates better limiting stops according to the invention. So the Figures 3 and 4 relate to a second embodiment forming a pivoting assembly of the resonator type.
  • the pivoting assembly 31 comprises an axis 32 rotatably mounted between two bearings 33 and 34 respectively mounted in a plate 35 and a bridge 36.
  • each bearing 33, 34 comprises at least one bearing 37, 38 and, preferably a bearing assembly 37, 38 - counter pivot 37 ', 38', is arranged to receive a pivot 39, 40 formed on each end of the axis 32.
  • a member forming a hairspring 41 is mounted between a bearing surface 44 of the pin 32 and an elastic washer 42.
  • the pin 32 comprises a rocker 43 and a plate 46 provided with a pin 47.
  • at least one of the two bearings 33, 34 comprises a limit stop 45 which is arranged to come into direct contact with the elastic washer 42 in order to restrict the relative displacement between the axis 32 and its bearings 33, 34.
  • each at least one bearing 37, 38 and, preferably, a bearing assembly 37, 38 - against a pivot 37 ', 38' is resiliently mounted in its associated bearing 33, 34 in order to cushion the impacts received. by the axis 32.
  • the elasticity is provided by a lyre spring 48, 49 respectively mounted between the plate 35 and the counter-pivot 37 ', and the bridge 36 and the pivot-pivot 38'.
  • the figure 5 relates to a third embodiment forming an alternating resonator-type pivoting assembly in the second embodiment.
  • the pivoting assembly 51 comprises an axis 52 rotatably mounted between two bearings 53 and 54 respectively mounted in a plate 55 and a bridge 56.
  • each bearing 53, 54 comprises at least one bearing 57, 58 and, preferably a bearing assembly 57, 58 - against pivot 57 ', 58', is arranged to receive a pivot 59, 60 formed on each end of the axis 52.
  • a member forming a hairspring 61 is mounted between a bearing of the axis 52 via a rocker 63 and an elastic washer 62.
  • the shaft 52 comprises a plate 66 with ankle.
  • at least one of the two bearings 53, 54 comprises a limit stop 65 which is arranged to come into direct contact with the elastic washer 62 in order to restrict the relative displacement between the axis 52 and its bearings 53, 54.
  • each at least one bearing 57, 58 and, preferably, a bearing assembly 57, 58 - against pivot 57 ', 58' is resiliently mounted in its associated bearing 53, 54 in order to cushion the impacts received. by axis 52.
  • the elasticity is provided by a spring-shaped 68, 69 respectively mounted between the plate 55 and the pivot 57 ', and the bridge 56 and the pivot pivot 58'.
  • said member or an additional member could thus be an escape anchor, an exhaust trigger, a mainspring barrel or ring, or a pendulum.
  • an axis may comprise two washers each attaching a separate member to one end of the axis, each limit stop of one of the two bearings of the axis being arranged to come into direct contact with one of the two washers in order to restrict the relative displacement between the axis and its bearings.
  • the pivoting assembly could also comprise a member formed, for example, of at least one anchor rod and mounted on an axis (also called rod) between two washers. elastic.
  • the member may also include pallets, a fork and a sting, each of which may have come form with the anchor rod or simply attached to the anchor rod.
