Definitions

  • the present invention relates to mechanical watch movements with automatic winding by oscillating weight.
  • the drum 17 of the barrel 16 rotatably mounted, coaxially with the mass 2, on five rollers with ball bearings 18.
  • the external face of the side wall of the drum 17 has a peripheral groove 19, of rectangular profile, into which the external raceways of the rollers 18 plunge.
  • the internal raceways of the rollers 18 are integral with tenons 20, the ends of which are also embedded in the crowns 10, 11.
  • FIG. shows that each stud 20 is planted in the crowns 10, 11 equidistant from the studs 9 of a pair of adjacent rollers 8.
  • These rings 10, 11 are fixed to the plate 14 in a manner not shown.
  • Fig. 2 shows that they in no way increase the thickness of movement 1.
  • the central opening of the drum 17 of the barrel 16 is forcibly engaged on the end of a sleeve 21, the central shape of which 22 makes it possible to support the shaft of the center or large medium wheel 23, when installing the needles.
  • the plug of the barrel 16 is constituted by a simple sleeve 24 on which is formed the anchoring hook 25 of the internal end of the spring 15.
  • the external raceways of two rollers 26 with ball bearings are embedded in the sleeve 24 , while the internal raceways of these rollers 26 are integral with the sleeve 21.
  • the sleeve 24 has 2 pins 27, which are engaged in corresponding cutouts of the ratchet 28 and fixed to the latter so as to secure that and the sleeve 24.
  • the winding train (Fig. 1 and 3), which connects the pinion 12 to the ratchet 28, in engagement with the toothing 6 of the crown 4 of the mass 2, comprises an inverter 29 of known type and three reduction gears 30, 31, 32.
  • the reverser 29 is composed of two pairs of wheels 33, 34; 35, 36.
  • Each of these pairs is pivoted in overhang in a roller with ball bearing 37, 38, the external raceway of which is forcibly engaged in a borehole of the plate 14.
  • the upper wheels 33 and 35 have the same diameter and are engaged with each other. While the lower wheels 34 and 36, also of the same diameter, but smaller than that of the upper wheels 33, 35, are mounted idly on their respective shafts, the upper wheels 33 and 35 are integral with the external raceways of two rollers at ball bearing 39, 40, the internal raceways of which are integral with the corresponding shafts.
  • Locking balls 41 are inserted between the two wheels of each pairs of the reverser 29. These balls 41 have the effect of securing the lower wheels 34, 36 to the respective upper wheels 33, 35, when the latter rotate in a direction, for example clockwise in FIG. 1, and to leave the lower wheels 34, 36 free when the upper wheels 33, 35 rotate in the opposite direction, counterclockwise.
  • the pinion 12 rotates clockwise, it will drive the wheel 33 counterclockwise and this in turn will drive the wheel 35 clockwise.
  • the wheel 36 will then be secured to the wheel 35 and it will drive the wheel of the mobile 30 counterclockwise.
  • the wheel 33 will then allow the wheel 34 to rotate freely, which will be driven clockwise by the wheel of the mobile 30.
  • the reduction gears 30, 31, 32 are pivoted by means of rollers with ball bearings 42, 43, 44 whose external raceways are embedded in the holes of the plate 14 , the mobiles 30 and 32 being mounted in cantilever.
