Description
Vorrichtung zum Verschieben der Schaltlinse an astronomischen Fernrohren bei Theodoliten mit Inneneinstellung, Die Erfindung betrifft eine Vorrichtung zum Verschieben der Schaltlinse an astronomischen Fernrohren bei Theodoliten mit Inneneinstellung. Der Erfindung gemäß wird die Triebschraube in der vorzugsweise horizontal gelagerten Schwenkachse des Fernrohres angeordnet. Dies hat den Vorteil, daß durch die Einstellung auf verschiedene Entfernungen, ,welche durch das Drehen an der Triebschraube erfolgt, eine Verstellung der Richtung des Fernrohres mit Sicherheit vermieden wird, wie sie bei den bekannten Fernrohren häufig eintrat.Device for moving the switching lens on astronomical telescopes in theodolites with internal adjustment, The invention relates to a device for Moving the switching lens on astronomical telescopes on theodolites with internal adjustment. According to the invention, the drive screw is preferably mounted horizontally Pivot axis of the telescope arranged. This has the advantage that by setting at different distances, which is done by turning the drive screw, an adjustment of the direction of the telescope is avoided with certainty, as it often occurred with the known telescopes.
Weiterhin ist infolge der neuen Anordnung die Lage der Triebschraube von der jeweiligen Fernrohrlage vollkommen unabhängig, so daß ohne weiteres das Einstellen an ein und derselben Stelle des Instrumentes unabhängig von der jeweiligen Fernrohrlage stattfinden kann. Ferner kann bei einer derartigen Anordnung die Triebachse sehr lang gemacht und somit sicher gelagert werden. Der Theodolit wird durch die der Erfindung entsprechende Ausgestaltung in keiner Weise verteuert, so daß also die Vorteile erzielt werden, ohne dafür Nachteile in den Kauf zu nehmen.Furthermore, as a result of the new arrangement, the position of the drive screw completely independent of the respective telescope position, so that the Adjustment at one and the same point of the instrument regardless of the respective Telescope position can take place. Furthermore, with such an arrangement, the drive axis can be made very long and therefore safely stored. The theodolite is made by the the embodiment corresponding to the invention in no way expensive, so that the advantages can be achieved without incurring any disadvantages.
Auf der Zeichnung ist beispielsweise eine Ausführungsform des Erfindungsgegenstandes dargestellt.The drawing shows, for example, an embodiment of the subject matter of the invention shown.
Abb. r zeigt einen Querschnitt durch das Fernrohr, Abb. 2 einen Längsschnitt durch dasselbe. Das Fernrohr a trägt den Ring b mit den daran angeordneten Lagerstützen c. Durch einen derselben ist die Achse d des Triebrädchens f gelagert und zu diesem Zweck der betreffende Lagerstutzen hohl ausgebildet. Außen ist die Achse d in üblicher Weise mit der vorderen Scheibe g versehen.Fig. R shows a cross section through the telescope, Fig. 2 shows a longitudinal section through the same. The telescope a carries the ring b with the bearing supports c arranged thereon. The axis d of the small pinion f is supported by one of these, and the bearing connection in question is hollow for this purpose. On the outside, the axis d is provided with the front disk g in the usual manner.
Das Triebrädchen f wirkt auf die Zahnstange lt ein. Diese Zahnstange h ist innen in dem Rohrstück i befestigt, welches die Schaltlinse k trägt und in dem Fernrohr a verschiebbar geführt ist.The drive wheel f acts on the rack lt. This rack h is fastened inside the pipe section i, which carries the switching lens k and in the telescope a is slidably guided.
Die Lagerstutzen c sind in üblicher Weise im Gestell des Theodoliten gelagert, so daß bei dem Ausführungsbeispiel die Lagerstutzen die wagerechte Schwenkachse des Fernrohres bilden, während zum Schwenken in der wagerechten Ebene das Gestell selbst entsprechend ausgebildet ist.The bearing stubs c are in the usual way in the frame of the theodolite stored, so that in the embodiment, the bearing support the horizontal pivot axis of the telescope form, while the frame to pivot in the horizontal plane itself is designed accordingly.
