Description

Einzahnscheibe für Maltesergetnebe mit verstellbarem Einzahnstift Bei Kinomaschinen ist es zur Erzielung eines einwandfreien Betriebes von großer Wichtigkeit, daß das Maltesergetriebe mit größter Genauigkeit ausgeführt wird. Von ganz besonderer Wichtigkeit bei diesem Getriebe ist das richtige Eingreifen des Einzahnstiftes in die Aussparungen des Malteserkreuzes.Single tooth disc for Maltesergetnebe with adjustable single tooth pin In the case of cinema machines, it is of great importance to achieve perfect operation It is important that the Geneva gear is carried out with the greatest possible accuracy. from Correct intervention of the is of particular importance with this transmission Toothed pin into the recesses of the Maltese cross.

Da zwischen dem Einzahnstift und den Aussparungen des Malteserkreuzes nur ein sehr kleines Spiel vorhanden sein darf, muß der Einzahnstift so genau passend in die Einzahnscheibe eingesetzt werden, daß beim Einlaufen des Stiftes in die Schlitze das Anstoßendes Einzahnstiftes an. eine der Schlitzflächen des Malteserkreuzes oder gar ein Eindringen in die Schlitze unter Zwang gegen eine Schlitzfläche unter allen Umständen vermieden wird.Because between the toothed pin and the recesses of the Maltese cross Only a very small amount of play is allowed, the single-tooth pin must fit exactly be inserted into the single tooth disc that when the pin enters the slots the butting of the single-tooth pin. one of the slotted surfaces of the Maltese cross or even penetration into the slots under duress against a slot surface under all Circumstances is avoided.

Die richtige Einstellung des Einzahnstiftes zu den Schlitzen des Malteserkreuzes wird zweckmäßig durch eine Feinverstellung des Stiftes, d. h. durch Veränderung des Abstandes des Einzahnstiftes zur Mitte der Einzahnscheibe erzielt.The correct setting of the single tooth pin in relation to the slots in the Maltese cross is expedient by fine adjustment of the pen, i. H. through change the distance between the single tooth pin and the center of the single tooth disk.

Gemäß der Erfindung wird diese Justierung des Einzahnstiftes einfach, betriebssicher und spielfrei dadurch erreicht, daß die Einzahnscheibe durch einen Schlitz in zwei Teile unterteilt wird und daB der Teil, in dem der Einzahnstift angebracht ist, dem anderen Teil der Einzahnscheibe z. B. mittels einer Schraube genähert bzw. von demselben entfernt werden kann.According to the invention, this adjustment of the single-tooth pin is simple, Reliable and backlash-free achieved in that the toothed disc by a The slot is divided into two parts and that the part in which the single-tooth pin is attached, the other part of the single tooth disc z. B. by means of a screw can be approached or removed from the same.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigt: Abb. i die Einzahnscheibe in Achsrichtung gesehen, Abb. z eine Ansicht senkrecht hierzu.In the drawing, the invention is shown in an exemplary embodiment, namely shows: Fig. i the single toothed disc seen in the axial direction, Fig. z a view perpendicular to this.

Der Einzahnstift i ist in der durch einen Schlitz 3 unterteilten. Scheibe :2 gelagert und mittels der Schraube q. radial verstellbar.The single-tooth pin i is divided by a slot 3. Washer: 2 mounted and using the screw q. radially adjustable.
