Description

Die Erfindung bezieht sich auf ein ein- und auskuppelbares Schneckengetriebe, wie es insbesondere bei Oszillierantrieben von Ventilatoren zur Anwendung kommt. Die Erfindung besteht im wesentlichen darin, daß das Ein- und Auskuppeln mittels der auf einer Welle axial verschiebbaren Schnecke erfolgt.The invention relates to a worm gear that can be engaged and disengaged, as it is used in particular with oscillating drives for fans. The invention consists essentially in the fact that the coupling and uncoupling means takes place on a shaft axially displaceable screw.

Weitere Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung und der zeichnerischen Darstellung eines Ausführungsbeispiels der Erfindung. Die Zeichnung zeigt dieses Ausführungsbeispiel in einem Längsschnitt, und zwar in Abb. I im eingekuppelten und in Abb. 2 im ausgekuppelten Zustand.Further features of the invention emerge from the following Description and the graphic representation of an embodiment of the invention. The drawing shows this embodiment in a longitudinal section, namely in Fig. I in the engaged state and in Fig. 2 in the disengaged state.

Mit I ist die Schnecke bezeichnet, die auf einer Welle lose drehbar und axial verschiebbar gelagert ist und mit dem Schneckenrad 6 im Eingriff steht. Am freien Ende der Schneckenwelle ist ein Mitnehmer 3 befestigt, der in eine Verzahnung der Schnecke I eingreift, so daß die Schnecke I mit ihrer Welle gekuppelt ist. Zur Axialverschiebung ist das rechte Ende der Schnecke I mit einer Ringnut 5 versehen, in die ein exzentrischer Mitnehmer des drehbaren Steuergliedes 4 eingreift. 2 ist eine in axialer Richtung wirkende - Federscheibe, an deren Stelle gegebenenfalls auch eine Druckfeder vorgesehen sein kann.I denotes the worm, which can be loosely rotated on a shaft and is axially displaceable and is in engagement with the worm wheel 6. At the free end of the worm shaft, a driver 3 is attached, which is in a toothing the screw I engages so that the screw I is coupled to its shaft. To the Axial displacement, the right end of the worm I is provided with an annular groove 5, in which an eccentric driver of the rotatable control member 4 engages. 2 is a spring washer acting in the axial direction, in its place if necessary a compression spring can also be provided.

In der Einkuppelstellung der Abb. I befindet sich die Mitte der Schnecke I genau im Eingriff mit dem Schneckenriad 6. Der Mitnehmer 3 greift in die Verzahnung der Schnecke I ein und kuppelt diese so mit ihrer Welle. Zum Auskuppeln wird das Steuerglied 4 um I8o° verdreht. Dadurch wird die Schnecke I nach rechts verschoben. Die Verbindung des Mitnehmers 3 und damit der Welle mit der Schnecke I wird gelöst, und die Schnecke I befindet sich in der Auskuppelstellung der Abb.2. In dieser Stellung legt sich die rechte Stirnfläche der Schnecke I mit leichtem Druck gegen die Federscheibe 2, wodurch ein Weiterlaufen der Schnecke I in der Auskuppelstellung verhindert wird.In the coupling position in Fig. I, the center of the worm is located I exactly in engagement with the worm wheel 6. The driver 3 engages in the toothing the screw I and so couples it with its shaft. This is used to disengage the clutch Control member 4 rotated by 180 °. As a result, the screw I is shifted to the right. The connection of the driver 3 and thus the shaft with the worm I is released, and the screw I is in the disengaged position of Fig.2. In this position The right end face of the worm I rests against the spring washer with light pressure 2, which prevents the screw I from continuing to run in the disengaged position.
