Definitions

  • This disclosure concerns a device for transforming oscillatory movement of a resonator for an electronic Watch into a continuous rotatory movement in which a click is rigid with the resonator driving the ratchet wheel, there being a first magnetized wheel adapted to be rotated by the ratchet wheel and a second magnetized wheel adapted to be rotated magnetically by the first magnetized wheel, the first and second magnetized wheels being mechanically separated from each other so that one of the magnetized Wheels can rotate independently of the other magnetized wheel, the first wheel having a lesser moment of inertia than the ratchet wheel but a greater thickness.
  • the oscillating movement of the resonator is generally transformed into a rotary movement for driving the gear train, by means of a click cooperating with a ratchet wheel, constituting the first wheel of the dial train.
  • the transformation of the movement is accompanied by a reduction of the frequency, the resonator operating at a frequency relatively high.
  • This device which has also the advantage of constituting a mechanical filter hindering the transmission of the jerky advance of the first ratchet wheel to the members of the movement, has nevertheless the major disadvantage, other than its complexity, of only attaining a relatively small efiiciency, of the order of 30%
  • the present invention has for its object to provide a device for transforming the oscillating movement of a resonator of an electronic watch into a movement of continuous rotation without jerks, having the same advantages as the double click, but of simpler construction and of greater efiiciency.
  • This device is characterised in that it comprises a click rigid with the resonator driving a ratchet wheel, a first magnetized wheel adapted to be rotated mechanically by the ratchet wheel, and a second magnetized wheel adapted to be rotated magnetically by the first magnetized wheel, the first and second magnetized 3,4i5 l,28fi Patented June 24, I969 formed of a blade 3 and a ruby pallet 4.
  • the latter drives a ratchet wheel 5 having a large number of teeth in the shape of isosceles triangles.
  • the wheel 5 carries on its shaft Ia magnetized polar wheel 8 cut so as to have six poles 9 alternately south and north.
  • This wheel 8 is consituted by an alloy of platinum cobalt of very high magnetic strength.
  • the magnetized polar wheel 8 drives a wheel 10 of large diameter, constituting the first wheel of the dial train.
  • the wheel 10 is constituted of a toothed crown 11, magnetized in the same manner as the wheel 8, mounted on a brass disc 12. Its rim is cut so as to form polar teeth 13 homologous to the poles 9 of the Wheel 8.
  • the driving of the wheel 10 by the wheel 9 takes place in a known manner which will not be described in any more detail.
  • the magnetic coupling between the wheels 8 and 10 is not chosen too high.
  • an airgap is provided between the poles 9 and the corresponding poles of the wheel 10 sufiicient so that the power transmitted is approximately equal to one microwatt (1 ,u.W.). This power is sufficient to drive the wheel 10 and the gear train, and also a date device, but it is negligible with respect to the power supplied by the resonator. During braking of the wheel 10 this demand on the battery of 1 ,uW. is also negligible.
  • This device for transforming the movement has the advantage of being of great simplicity, of avoiding to a large degree losses of power due to friction, and of constituting an excellent mechanical filter isolating the resonator [from the gear train. Moreover, the precision of the wheels 8 and 10 can be much lower than that of wheels of mechanical engagement. Thus it is possible to make entirely independently, on the one hand the oscillator with its device for transforming the movement comprising the click, the ratchet wheel and its polar wheel 8, and on the other hand the gear train mounted on the plate and including the wheel 10, and to assemble then without difliculty these two parts.
  • the wheel 10 can be made in la ferro-nickel alley or even in soft iron.
  • a device for transforming oscillatory movement of a normally vibrating resonator of an electronic watch into a continuous, smooth, rotatory movement comprising:
  • the second wheel being positioned in the same plane as said first wheel and being adapted to be driven magnetically by the first wheel; said second wheel being rotatable against or lockable relative to said first wheel when said watch is set;
  • a device for transforming oscillatory movement of a normally vibrating resonator of an electronic Watch into a continuous, smooth, rotary movement comprising:
  • the second wheel being positioned in the same plane as said first wheel and being adapted to be driven magnetically by the first wheel; said second wheel being rotatable against or lockable relative to said first wheel when said watch is set;
  • a device for transforming oscillatory movement of a normally vibrating resonator of an electronic watch into a continuous, smooth, rotary movement comprising:
  • a device for transforming oscillatory movement of a resonator for an electronic Watch into a continuous, smooth, rotary movement comprising:
  • a device for transforming oscillatory movement of a resonator for an electronic watch into a continuous, smooth, rotary movement comprising:
  • a device for transforming oscillatory movement of a resonator tor an electronic watch into a continuous, smooth, rotary movement comprising:
