Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft ein Zahnräderwechselgetriebe mit seitlich verschiebbaren Zahnrädern. Das Wesen, der Neuerung liegt darin, daß das Verschieben der Räder mittels zweier in einer Achse ineinander liegender mehrgängiger Schraubenspindeln erfolgt.The invention relates to a gear change transmission with laterally displaceable gears. The essence of the innovation lies in the fact that the wheels can be moved by means of two in an axis of nested multiple screw spindles takes place.

Bei Werkzeugmaschinen mit Räderkastenantrieb für mittlere und größere Kräfte, bei welchen der Kasten möglichst kleine Abmessungen haben soll.und dies durch andere Wechselvorrichtungen nicht erreicht werden kann, findet diese neue Anordnung Verwendung; außerdem wird durch den Schraubenspindelantrieb zum Verschieben der Zahnräder ein leichtes und stoßfreies Ein- und Ausrücken erzielt.For machine tools with gear box drive for medium and large forces, at which the box should have the smallest possible dimensions. and this by others Changing devices cannot be reached, this new arrangement is used; In addition, the screw spindle drive for moving the gears enables easy and shock-free engagement and disengagement achieved.

Die Verstellung erfolgt durch zwei Handräder, welche je auf einer in derselben Achse befindlichen mehrgängigen Spindel sitzen. Zu diesem Zwecke besitzt die eine Spindel eine Durchbohrung, durch welche die andere Spindel hindurchführt. Auf diesen Schraubenspindeln sitzen zwischen je einem Zahnräderpaare die Verschiebegabeln. An die letzteren sind durch einen Schlitz des Gehäuses reichende Zeiger angeschraubt, welche die jeweilige Schaltung an einer Teilung anzeigen.The adjustment is made by two handwheels, each on one in the same axis located multi-thread spindle sit. For this purpose one spindle has a Through hole through which the other spindle passes. On these screw spindles the sliding forks sit between each pair of gears. To the latter are screwed through a slot in the housing reaching pointers, which the respective Show circuit at a division.
