Definitions

  • the present invention relates to an astronomical watch by means of which it is possible to read astronomical quantities directly by means of indicators moving above a dial representing the planisphere.
  • Such timepieces are called "astrolabes”.
  • Document CH-A-627 042 also discloses a watch comprising two faces, one provided with means for indicating the time, the date and the moon phase in particular, and the other with superimposed discs, rotating around a common axis, each disc carrying the distinctive sign of a planet.
  • the drive means of the discs comprise superposed wheels, coaxial with the latter, at the rate of one wheel per disc.
  • such an arrangement requires a significant thickness.
  • the invention aims to provide an astronomical watch that can be worn on the wrist and combines small dimensions with high precision, while having the robustness and reliability that can be expected from a wristwatch.
  • an astronomical timepiece which includes a time reference with mechanical output which, via a train of planetary gears, is coupled to at least one indicator of astronomical magnitude, the crown and the wheel.
  • planetary drive of this train being coupled to said time reference, said planetary gear train comprising, for each indicator of astronomical magnitude, a gear train with multiple mobiles of predetermined reduction ratio.
  • the timepiece has the dimensions of a wristwatch, that is to say that can be worn on the wrist
  • the satellite carrier comprises two parallel and braced plates rotatably mounted around the axis of movement in a support ring by means of an outer bearing coaxial with this axis.
  • the astronomical module 8 is housed in a support ring 11 (FIG. 2) which has an L-shaped section and is composed of a ring 12 receiving the feet 13 of the planisphere 6 and a flange 14 ending in a rib. annular 15 which defines a bearing surface 16 against which abuts an additional annular rib 18 of movement C.
  • a cage which constitutes the planet carrier of a planetary gear train 19 is rotatably mounted around the axis of the module 8 in the support ring 11 by means of a ball bearing 20. It supports the mobiles of the astronomical module which form the planetary train satellites.
  • the planetary gear 19 comprises two parallel and perforated plates 21 and 22 (see also FIGS. 6, 7 and 9) suitably braced and fixed to one another. They are integral with a ring 23 which comprises a peripheral circular body 24 from which extends inward a flange 25 serving on the one hand for fixing the plates by screws 26 and on the other hand for defining an internal toothing 27 (Figure 2) by means of which the cage of the planetary gear 19 is rotated. This internal toothing forms the crown of the planetary gear.
  • the bearing 20 comprises a row of balls 28 retained in an annular housing 29 which is delimited (FIG. 3A),
  • the annular housing 29 is closed by a washer 33 screwed by screws 34 (FIG. 3) into the annular body 24.
  • the outer lower edge 33a of this washer is also in contact with the balls 28.
  • the annular housing 29 is of overall square section which can be obtained by convenient machining operations whose precision can be easily ensured, unlike the bearings which are usually used in watchmaking, in automatic mechanical watches, for example, in which the raceways have a V-shaped section or a portion of a circle.
  • the balls 28 are held radially by the annular vertical walls of the housing 29 while the four sharp edges 30a, 30b, 32a and 33a, also annular, provide axial guidance.
  • the bearing 20 being at the periphery of the module B, it is possible to use a large number of free balls (that is to say not mounted in a basket).
  • the bearing surface of the bearing is therefore very large, which increases the stability of the bearing.
  • the number of contact points makes it possible to use relatively soft metals for the raceways.
  • FIG. 3 also shows that the movement C comprises a plate 35 which is pressed against the bearing surface 16 by pressure plates 36 attached to the flange 14.
  • the plate 35 carries in its center a fixed hollow shaft 37 on which 38 and 38 hour mobiles are pivoted, performing one revolution per hour and one revolution in 12 hours respectively.
  • the minutes mobile 38 includes a carriageway 40 mounted on the fixed shaft 37, a minute wheel 41 meshing with the gear train 42 of movement C and frictionally mounted on the carriageway 40, and a wheel d drive 43 of a gear train 44 of the planetary gear cage 19.
  • the hours mobile 39 has an hours wheel 45, a barrel 46, and an hours pinion 47.
  • the minutes mobile 38 is kinematically connected to the hours mobile 39 by a timer mobile comprising a timer wheel 48 and a pinion.
  • timer 49 pivotally mounted on a tenon 50 integral with the plate 35.
  • the wheel 48 meshes with a pinion 51 formed on the roadway 40, while the timer pinion 49 meshes with the hour wheel 45.
  • the minute and minute gears timer and the timer and hour wheels are calculated so that the reduction ratio between the minute hand and the hour hand is one to twelve.
  • the carriageway 40 and the barrel 46 respectively carry, on their free end, the minute hand 5 and the hour hand 4.
  • the cage of the planetary gear 19 is rotated by the train 44 which has two mobiles 52 and 53 ( Figure 2).
  • the first of these mobiles, mounted on a tenon 54 secured to the plate 35, comprises a wheel 55 which meshes with the drive wheel 43 and a pinion 56.
  • the second mobile of this cog train pivots on a tenon 57 secured to the plate 35. It comprises a wheel 58 which meshes with the pinion 56 and a pinion 59 which meshes with the internal toothing 27 of the ring 23.
  • the drive wheel 43, the pinions and the wheels of the cog train mobiles 44 and the internal toothing 27 of the ring 23 are calculated so that their gear ratio is from 1 to 24. In this way, the minutes mobile makes 24 turns while the planetary gear cage 19 only performs a.
  • the cage or planet carrier 21, 22 (FIG. 2) carries, in its central part, mounted on the lower plate 22, a tube 60, coaxial with the hours and minutes mobiles. This tube therefore makes one revolution per 24 hours. It carries the solar needle 8.
  • the tube 60 comprises a flange 61 on which a spring 62 is supported, coming to bear moreover on the hours pinion 47.
  • the tube 60 also carries, mounted coaxially around each other, a lunar wheel 63, a dragon wheel 64 and a spider wheel 65.
  • Each of these three wheels comprises on the one hand a cannon on which the moon needle, the dragon needle and the spider are fixed respectively , and a board whose periphery is provided with a toothing enabling them to be driven, by means of a gear train.
  • gear trains are mounted on the cage or planet carrier 21, 22, so that they all perform a planetary movement relative to the main axis of the watch.
  • the mobiles 60, 63, 64 and 65 constitute coaxial planets of the planetary train of the astronomical module.
  • Figures 4, 6, 7 and 9 show further that two gear trains among the three used here have a common part, namely that ensuring the drive of the lunar hand 9 and that which allows the spider 7 to spin. It will also be noted that for the purpose of the representation, the sections of Figures 5 and 8 are made on the axes of rotation of the mobiles which make up the gear trains, so that these figures show the central axis of the workpiece. clockwork to the right and left of the representation.
  • the mobile under consideration of the gear trains will be designated by a numerical reference without literal index, the wheels and the pinions of each mobile respectively carrying this numerical reference followed by the index a or b.
  • the train of the lunar hand thus comprises a mobile 66 whose wheel 66a meshes with the hour pinion 47, then three other mobiles 67, 68 and 69, the wheel of the last mobile driving the lunar wheel 63 (the pinion of this mobile 69b is not used for the transmission of movement to the moon wheel). (Fig. 5 and 6).
  • the spider 7 is rotated by means of the mobiles 66, 67 and 68, the mobile 69 participating here entirely in the transmission by means of the pinion 69b which meshes with a mobile 70 whose pinion 70b is engaged with the spider wheel 65. (Fig. 5 and 7).
  • the dragon's needle 10 is driven by a gear train whose input is the moon wheel 63 and which includes mobiles 71 and 72. (Fig. 8 and 9).
  • FIG. 10 shows a device for adjusting the astronomical module B.
  • the time-setting rod 73 of the movement C comprises a sliding pinion 74 which, in one of its positions, meshes with a mobile 75 an adjustment train, further comprising a wheel 76 and a mobile 77, the latter meshing with the toothing 27 of the ring 23.
  • this adjustment device makes it possible to adjust the various indicators of the astronomical module by direct drive of the planet carrier 21, 22.
