Definitions

  • the invention relates to a clock shock wheel for driving a component having a non-zero imbalance with respect to a pivot axis of said wheel, which wheel comprises, firstly a shaft for its guidance in pivoting about said pivot axis, and secondly driving means arranged or reported on a flange that includes said wheel, said wheel having at least one flexible element between said shaft and said flange.
  • the invention also relates to a watch movement comprising such a wheel bearing a said component having a non-zero unbalance with respect to a pivot axis of said wheel.
  • the invention also relates to a watch comprising at least one such watch movement.
  • the invention relates to the field of the protection of watches against the effects of shocks, particularly when they include moving components with a large imbalance that may damage a more fragile element of the drive train during an impact.
  • the invention aims to prevent breakage of the wheels and / or the rotor by absorbing the energy of the shock, without impacting the design of the needles. Indeed, if we can add a counterweight to the needles to reduce their imbalance, and thus reduce the torque exerted during a major shock, this type of solution alters the appearance of the needles desired by manufacturers.
  • shock energy is necessary to allow the use of needles with significant unbalance, even more common with the current trend to increase the diameter of watches.
  • the basic principle of the invention is to absorb the shock by allowing elastic torsion at a component of the train, and particularly the center wheel. This torsion is achieved by sliding between the shaft 2 of the center shaft and the flange 8.
  • An elastic element makes it possible to absorb the impact.
  • the sliding tube / board allows to dissipate some energy in friction.
  • the elastic element makes it possible to modify the amplitude and duration of the shock (lower amplitude and longer duration).
  • the invention relates to a clock shock wheel for driving a component having a non-zero imbalance with respect to a pivot axis of said wheel, which wheel comprises, on the one hand a shaft for its guidance in pivoting about said pivot axis, and secondly drive means arranged or reported on a flange that comprises said wheel, said wheel comprising at least one flexible element between said shaft and said flange, characterized in that that said flange comprises a cylindrical bearing cooperating in centering bearing with a complementary cylindrical surface that includes said shaft to ensure the perfect concentricity of said drive means with said shaft.
  • said flexible element is an interchangeable element distinct from said shaft and said flange and whose resilience is chosen as a function of the maximum permissible value of said unbalance.
  • the invention also relates to a watch movement comprising such a wheel carrying a said component having a non-zero imbalance relative to a pivot axis of said wheel, characterized in that said component is a needle, or an oscillating weight, or a hammer ring, or a rocker.
  • the invention also relates to a watch comprising at least one such watch movement.
  • the invention proposes to improve the protection of watches against the effects of shocks.
  • the effect of a large impact on a moving component with a large unbalance may damage the most fragile elements of the driveline.
  • the invention relates to a watch shock wheel 1 for driving a component 4 having a non-zero unbalance B relative to a pivot axis D of the wheel 1.
  • This wheel 1 comprises, on the one hand a shaft 2 for its guidance in pivoting about the pivot axis D, and on the other hand drive means 7 arranged or reported on a flange 8 that includes the wheel 1.
  • These drive means 7 may be a toothed sector, a belt track or chain or the like, or other.
  • the wheel 1 comprises at least one flexible element 9 between the shaft 2 and the flange 8, to absorb the impact due to impact, and dampen the effect on the other components of the watch movement 100, in which the wheel 1 is incorporated. according to the invention.
  • this flange 8 comprises a cylindrical bearing surface 81 cooperating in centering bearing with a complementary cylindrical bearing surface 21 that comprises the shaft 2 to ensure the perfect concentricity of the drive means 7 with the shaft 2.
  • the geometry is thus always perfectly assured, as well as the precision of the motion transmission. This arrangement ensures the absence of any false round, as well as any parasitic vibration due to an extremely small game.
  • the first three modes, illustrated in Figures 1 to 34 relate to an advantageous variant of the invention, in which the flexible element 9 is an interchangeable element distinct from the shaft 2 and the flange 8.
  • the resilience of this flexible element is chosen as a function of the maximum permissible value of the unbalance B .
  • the flexible elements 9 are substantially flat circular seals, and are wedged between the flange 8 and the shaft 2.
  • the flange 8 pivots on the shaft 2.
  • a washer resting on the 2 and riveted on it makes an axial stop of the flange 8.
  • the seals allow to transmit the torque between the flange 8 and the shaft 2. During an impact, these joints deform and absorb some of the energy of the shock. When the shock is over, the flange 8 returns to its initial position relative to the shaft 2.
  • the shock is absorbed directly at the center wheel 1. That is to say that the energy shock, exerted by the unbalance needle, is absorbed at the earliest in the transmission chain torque.
  • the anti-shock wheel 1 illustrated in the form of a minute wheel, comprises a toothed flange 8 with a toothing 7, centered on a shaft 2, and fixed to this shaft 2 by a bayonet mechanism.
