PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Schraubenradtriebwerk, welches die Verdopplung des Übersetzungsverhältnisses zwischen treibender und getriebener Welle und die Umkehrung der Drehrichtung der zu treibenden Welle bei gleichbleibender Drehrichtung der getriebenen Welle ermöglicht.The invention relates to a helical gear, which doubles the gear ratio between the driving and driven shaft and the reversal of the direction of rotation of the shaft to be driven allows constant direction of rotation of the driven shaft.
Der Gegenstand der Erfindung ist in Fig. ι der Zeichnung in einer Ansicht und in Fig. 2The subject of the invention is shown in FIG. 1 of the drawing in a view and in FIG. 2
ίο in einem Längsschnitt veranschaulicht.ίο illustrated in a longitudinal section.
α stellt ein Schneckenrad dar, dessen Umfang in bekannter Weise mit kegeligen Rollen c versehen ist. Diese Rollen c sind um Zapfen d drehbar. Auf einer Welle e sind drei Schnecken/1,/2,/3 verschiebbar durch einen Hebel g angeordnet. Das Schneckenrad α läßt sich ebenfalls auf seiner viereckigen Welle h durch einen Hebel i verschieben. Die Schnecke/1 trägt eingängiges rechtes Gewinde, die Schnecke/2 zweigängiges rechtes Gewinde und die Schnecke /3 eingängiges linkes Gewinde. Die Steigung der Schnecken ist bei allen drei Schnecken der Teilung der auf dem Umfang α sitzenden Rollen c entsprechend gewählt. Durch seitliche Verschiebung des Rades α auf seiner Welle h wird eine Verschiebung der Schnecken/auf der Welle e ermöglicht, so daß nach Belieben eine der drei Schnecken zum Eingriff mit dem Rollenschneckenrade α gebracht werden kann und hierdurch die Drehung des Rades α bei gleicher Umdrehungszahl und Umdrehungsrichtung der Welle e verdoppelt oder in ihrer Richtung umgedreht wird. α represents a worm wheel, the circumference of which is provided with tapered rollers c in a known manner. These rollers c are rotatable about pin d. On a shaft e , three screws / 1 , / 2 , / 3 are arranged such that they can be displaced by a lever g. The worm wheel α can also be moved on its square shaft h by a lever i . The worm / 1 has a single-start right thread, the worm / 2 has a two-start right thread and the worm / 3 has a single-start left thread. In all three screws, the pitch of the screws is selected according to the pitch of the rollers c seated on the circumference α. By lateral displacement of the wheel α on its shaft h allowing a displacement of the worm / on the shaft e, so that can be brought α as desired one of the three screw for engagement with the Rollenschneckenrade and thereby the rotation of the wheel α at the same speed of rotation and Direction of rotation of the shaft e is doubled or reversed in its direction.
