Description

Anordnung an Schneckenradmaschinen. Es ist ein Mißstand bei Schneckengetrieben, wie sie an Schneckenradmaschinen zum Pumpen von Flüssigkeiten oder zur Erzeugung eines Antriebes verwendet werden, besonders wenn in der Globoidform der Schnecke diese in einen größeren Bogen des Schneckenrades eingreift, daß Schnecke und Schneckenrad nicht ohne weiteres zusammengebaut werden können. Man hilft sich hier meistens dadurch, daß man den Schneckenradzähnen ein nach außen spitzes Profil gibt, damit sie in die Schneckengänge eingeführt werden können. Hierdurch wird der Hohlraum der Schnecke, welcher den Arbeitsraum darstellt, verkleinert. Um die für solche Maschinen günstigste hinterschnittene Form der Gänge anwenden zu können, soll durch den Erfindungsgegenstand ein Mittel geschaffen werden, um das Schneckenrad ohne weiteres zwischen die hinterschnittenen Zähne der Schnecke einführen zu können. Zu diesem Zweck soll nach der Erfindung der Schneckenradkranz radial teilbar ausgeführt sein. Hierdurch erreicht man den Vorteil, daß man die Teile des Kranzes nacheinander in die hinterschnittenen Schraubengänge eindrehen kann. Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung im Schnitt von der Seite dargestellt. Die hohl gewölbte Schnecke a greift in das Schneckenrad b auf einen großen Bogen des Umfanges ein. Früher mußten, um einen Zusammenbau zu ermöglichen, die Zähne des Schneckenrades in der strichpunktierten Weise ausgebildet sein. Will man aber hinterschnittene Zähne b1, b2 verwenden, so legt man durch den Radkranz eine oder mehrere Teilungsfugen e, durch welche dieser in einzelne Stücke zerlegt werden kann. Man ist hierdurch in der Lage, zunächst den einen und dann die anderen Teile des Radkranzes unter Drehung der Schnecke a in die Schneckengänge einzuführen,Arrangement on worm gear machines. There is a malady with worm gears, like those on worm gear machines for pumping liquids or for generating of a drive can be used, especially if the worm is in the globoid form this engages in a larger arc of the worm wheel that worm and worm wheel cannot be easily assembled. One usually helps oneself here by that one gives the worm gear teeth an outwardly pointed profile so that they are in the worm threads can be introduced. This creates the cavity of the screw, which represents the working space, reduced in size. To the cheapest for such machines To be able to use the undercut shape of the passages is intended by the subject matter of the invention A means can be created to easily move the worm wheel between the undercut To be able to introduce teeth of the snail. To this end, according to the invention the worm wheel rim be designed to be radially divisible. This is how you reach the Advantage of the parts of the ring one after the other in the undercut screw threads can screw in. An embodiment of the subject matter of the invention is shown in the drawing shown in section from the side. The hollow domed snail a engages in the Worm wheel b on a large arc of the circumference. I used to have to get one To enable assembly, the teeth of the worm wheel in the dash-dotted line Way to be trained. But if you want to use undercut teeth b1, b2, so you put one or more dividing joints e through the wheel rim, through which it can be broken down into individual pieces. This enables you to start with one and then the other parts of the wheel rim while turning the worm a to be introduced into the worm threads,
