Die Bodenplatine 6 und die Deckplatine 7 sind durch Schrauben 30 verbunden und bilden ein im wesentlichen geschlossenens Gehäuse, in welchem das Planetenradgetriebe angeordnet ist. Im Zentrum der beiden Platinen sind jeweils Durchgangslöcher 31,32 vorgesehen, deren Zweck später erläutert wird.The bottom plate 6 and the top plate 7 are connected by screws 30 and form a substantially closed housing in which the planetary gear is arranged. Through holes 31, 32 are provided in the center of the two boards, the purpose of which will be explained later.

Die vorstehend beschriebene Vorrichtung wird erfindungsgemäss in eine Uhr, z.B. eine Armbanduhr eingebaut. Die Uhr hat ein zweiteiliges Gehäuse 41 bestehend aus Mittelteil-Glasreif 42 und Boden 43, ein Uhrglas 44, ein Uhrwerk 45, einen Minutenzeiger 46, einen Stundenzeiger 47, ein Zifferblatt 48 und eine Stelleinrichtung mit einer Krone 49.The device described above is according to the invention in a watch, e.g. built in a wristwatch. The watch has a two-part housing 41 consisting of a central section bezel 42 and base 43, a watch glass 44, a watch mechanism 45, a minute hand 46, an hour hand 47, a dial 48 and an actuating device with a crown 49.

Im Uhrgehäuse 41 ist ein Ring 50 angeordnet, der eine rinnenförmige Ausnehmung 51 aufweist. Der Ring 50 ist unterhalb der Rotationsebene der Mondkugel 1 so angeordnet, dass ein Abschnitt der Mondkugel 1 in die Ausnehmung 51 ragt.A ring 50 is arranged in the watch case 41 and has a groove-shaped recess 51. The ring 50 is arranged below the plane of rotation of the moon ball 1 such that a section of the moon ball 1 projects into the recess 51.

Wie Fig.2 zeigt, ist die Baueinheit direkt auf die Oberseite des Uhrwerkes 45 montiert. Das Minutenrohr 52 und das Stundenrohr 23 ragen durch die Bohrungen 31,32 in den Platinen 6 und 7, um die entsprechenden Zeiger 46,47 zu montieren. Das Zifferblatt 48 ist direkt auf der auf der Deckplatine 7 angeordnet und hat einen Rand 54, um die Deckplatine vollständig abzudecken ( Fig. 2 ).As FIG. 2 shows, the assembly is mounted directly on the top of the clockwork 45. The minute tube 52 and the hour tube 23 protrude through the holes 31, 32 in the plates 6 and 7 in order to mount the corresponding pointers 46, 47. The dial 48 is arranged directly on the cover plate 7 and has an edge 54 in order to completely cover the cover plate (FIG. 2).

Die Baueinheit wird erfindungsgemäss so auf dem Uhrwerk 45 angeordnet, dass die Mondkugel 1 über einer gedachten Sonne steht, deren Stellung in der 12 Uhr Position des Uhrwerkes 45 festgelegt ist, und dass die Mondkugel 1 in der 12 Uhr Position mit der dunklen Hälfte zum Uhrglas 44 und mit der hellen Hälfte zur gedachten Sonne gerichtet ist. Um die Einstellung der Mondkugel 1 bezüglich der Sonne zu erleichtern, kann am Uhrgehäuse 41 oder am Uhrglas 44 eine Markierung (nicht dargestellt) vorgesehen werden.According to the invention, the structural unit is arranged on the clockwork 45 such that the moon ball 1 over a imaginary sun is standing, the position of which is fixed in the 12 o'clock position of the clockwork 45, and that the moon ball 1 in the 12 o'clock position is directed towards the watch glass 44 with the dark half and towards the imaginary sun with the light half. In order to facilitate the setting of the moon ball 1 with respect to the sun, a marking (not shown) can be provided on the watch case 41 or on the watch glass 44.

Die Drehung der Mondkugel 1 erfolgt durch das Stundenrohr 23 und über das differo-epizyklische Planetenradgetriebe, gebildet durch das Ritzel 13 der Mondkugel, die Zahnkränze 2 und 3 und das Räderwerk 5. Somit erfolgt die Drehung der Mondkugel erfindungsgemäss über zehn verzahnte Glieder und sieben Achsen.The moon ball 1 is rotated by the hour tube 23 and the differential epicyclic planetary gear, formed by the pinion 13 of the moon ball, the sprockets 2 and 3 and the gear train 5. Thus, according to the invention, the moon ball is rotated via ten toothed links and seven axes .

Das Stundenrohr 23 treibt den ersten Trieb 21, dessen Ritzel 22 das Zwischenrad 24 antreibt. Das Ritzel 25 des Zwischenrades 24 kämmt mit dem ersten Zahnrad 27 des zweiten Triebes, dessen zweites Zahnrad 28 mit der gleichen Drehzahl dreht. Das erste Zahnrad 27 dreht den ersten Zahnkranz 2 mit dem Lagerring 4 und der darin gelagerten Mondkugel 1, so dass diese im Uhrzeigersinn das Zifferblatt rotiert. Das zweite Zahnrad 28 dreht den den zweiten Zahnkranz 3. Da der erste und zweite Zahnkranz 2,3 sowie das erste und zweite Zahnrad 27,28 des zweiten Triebes jeweils unterschiedliche Zähnezahlen haben, rotieren der erste und zweite Zahnkranz 2 und 3 mit unterschiedlicher Drehzahl, wobei der zweite Zahnkranz 3 auf dem Lagerring 4 gleitet. Durch die Drehzahldifferenz der beiden Zahnkränze 2,3 führt die über das Ritzel 13 mit dem zweiten Zahnkranz 3 in Eingriff stehende Mondkugel 1 eine linksgängige Eigendrehung aus.The hour tube 23 drives the first drive 21, the pinion 22 drives the intermediate wheel 24. The pinion 25 of the intermediate gear 24 meshes with the first gear 27 of the second drive, the second gear 28 rotates at the same speed. The first gear 27 rotates the first ring gear 2 with the bearing ring 4 and the moon ball 1 mounted therein, so that it rotates the dial clockwise. The second gear 28 rotates the second ring gear 3. Since the first and second ring gear 2, 3 and the first and second gear wheel 27, 28 of the second drive each have different numbers of teeth, the first and second ring gears 2 and 3 rotate at different speeds, the second ring gear 3 sliding on the bearing ring 4. Due to the speed difference of the two ring gears 2, 3, the moon ball 1, which engages with the second ring gear 3 via the pinion 13, performs a left-hand rotation.

Dadurch wird die Mondkugel einerseits in 29,53 Tagen einmal im Uhrzeigersinn um das Zifferblatt gedreht und führt andererseits die Eigendrehung in dieser Zeit aus, derart, dass der helle Abschnitt der Mondkugel 1 immer zur gedachten Sonne gerichtet ist und dass die Mondphasen gemäss der am Himmel sichtbaren wiedergegeben wird.As a result, the moon is rotated clockwise once around the dial in 29.53 days and, on the other hand, performs its own rotation during this time, such that the bright section of moon ball 1 is always directed towards the imaginary sun and that the phases of the moon correspond to those in the sky visible is reproduced.

Zur Verstellung der Mondkugel 1 ist das Uhrwerk 45 mit einem zusätzlichem Stellrad 55 ausgerüstet, das mit dem ersten Zahnrad 27 des zweiten Triebes in Eingriff steht. Die Verstellung der Mondkugel 1 erfolgt über die Krone 49. Es ist aber auch möglich eine separate Einstellvorrichtung vorzusehen.To adjust the moon ball 1, the clockwork 45 is equipped with an additional adjusting wheel 55, which is in engagement with the first gear 27 of the second drive. The moon ball 1 is adjusted via the crown 49. However, it is also possible to provide a separate adjusting device.
