Description
Schieberkolben für Drebkolbenmaschinen mit sichelförmigem Arbeitsraum und Führung der Kolben in seitlichen Bahnen, die zwischen der Zylinderwandung und Ansätzen der . Zylinderdeckel gebildet sind. Gegenstand der Erfindüng ist eine Verbesserung der Schieberkolben für Drehkolbenmaschinen mit sichelförmigem Arbeitsraum, bei welchen die Schieberkolben durch an den Zylinderdeckeln befindliche exzentrische Ansätze zwischen diesen und der Zylinderwandung geführt werden. -Das Neue besteht im wesentlichen darin, daß die einzelnen Schieberkolben in Hub- und Führungsschieber unterteilt sind.Slide pistons for three-piston machines with sickle-shaped working space and guiding the piston in lateral paths between the cylinder wall and Approaches of. Cylinder covers are formed. The subject of the invention is an improvement the slide piston for rotary piston machines with a sickle-shaped working space, in which the spool through eccentric lugs on the cylinder covers be guided between these and the cylinder wall. -The new is essentially in that the individual slide pistons are divided into lift and guide slides are.
In der Zeichnung ist der Erfindungsgegenstand dargestellt: Fig. i zeigt die Maschine im Längsschnitt, Fig. z einen Querschnitt durch .die Mitte. Fig. 3 stellt einen Schnitt nach Linie A-B der Fig. i dar.The subject of the invention is shown in the drawing: FIG shows the machine in longitudinal section, Fig. z shows a cross section through .the middle. Fig. 3 shows a section along line A-B of FIG.
Fig. 4. läßt im größeren Maßstabe die seitliche Abdichtung der Führungsschieber erkennen, während -Fig. 5 und 6 einige Ausführungsarten von Verbindungen der Hub- und Führungsschieber wiedergeben.Fig. 4. leaves the lateral sealing of the guide slide on a larger scale recognize while -Fig. 5 and 6 some types of connections of the hub and guide slide.
Die Schieberkolben sind dreiteilig. Sie bestehen aus einem in der Kolbentrommel verschiebbaren Mittelteil a (Hubschieber) und zwei seitlichen; in der Führungsbahn radial laufenden Teilen b b (Führungsschieber), die mit ersterem Teil wegen der Exzentrizität von Kolbentrommel und Führungsbahn drehbeweglich verbunden sind.The slide pistons are in three parts. They consist of one in the Piston drum displaceable middle part a (lifting slide) and two lateral; in the guideway radially running parts b b (guide slide), which with the former Part rotatably connected because of the eccentricity of the piston drum and guideway are.
Die Führungsschieber b besitzen allseitig breite Tragleisten c, so daß ein Verkannten verhindert uild ein gutes Abdichten gewährleistet ist, wozu Schmiernuten d beitragen.The guide slides b have wide support strips c on all sides, see above that a misunderstanding prevents uild good sealing is guaranteed, including lubrication grooves d contribute.
In Fig. 5 und 6 sind einige Ausführungsarten der Verbindung zwischen Hub- und Führungsschieber veranschaulicht. In. Fig. 5 hat der Hubschieber a an dien Stoßstellen reichlich Spiel,.so daß dem Erfordernis seiner Drehbeweglichkeit im Führungsschieber Rechnung getragen ist. Nieten oder Bolzen nehmen die Schleuderkräfte auf. In Fig.6 erfolgt die Drehung mittels eines Zapfens. Zweckmäßig ist es, die Hubschiebern an der Gehäusewandung etwa .o,1 mm abstehen zu lassen (s. Fig. 4), damit ein Anschlagen der Schieber vermieden wird.In Figs. 5 and 6 are some embodiments of the connection between Lift and guide slide illustrated. In. Fig. 5 has the lift slide a to serve Joints abundant play, so that the requirement of its rotational mobility in the Guide slide is taken into account. Rivets or bolts take the centrifugal forces off on. In Figure 6, the rotation takes place by means of a pin. It is useful that Allow lifting slides to protrude about 0.1 mm from the housing wall (see Fig. 4), so that the slider does not hit.
In der Längsrichtung der Führungsschieber ist ein Wärmedehnungsspiel x zweckmäßig. Damit dieses seitliche Spiel zwischen Kolbentrommel und Zylinderdeckel auf ein Mindestmaß beschränkt bleibt, sind an den Stirn-, flachen der Kolbentrommel keilförmige Anlaufflächen e . vorgesehen, die bewirken, daß die Führungsschieber seitlich an den Zylinderdeckeln auf dem Wege g, 1z, i (s. Fig. 3), dem Verdichtungsabschnitt, abdichten. - Auf dem Saugabschnitt g, k, i findet eine solche Abdichtung nicht statt, da die Schieber hier aus dem Bereich der Anlaufflächen infolge der Exzentrizität von Kolbentrommel und Führungsbahn heraustreten und sich - in dem Spalt f verschieben können. Dies ist jedoch nicht von großer Bedeutung, da der Druck in den Zellen des Saugabschnittes verhältnismäßig gering ist. Letzteres bezieht sich auch auf die Verluste infolge des Spaltes f. Die Anlaufflächen e können auch durch besonders federnde Einlegeplatten ersetzt werden.A heat expansion clearance x is appropriate in the longitudinal direction of the guide slide. So that this lateral play between the piston drum and the cylinder cover remains limited to a minimum, wedge-shaped contact surfaces e are provided on the flat faces of the piston drum. provided, which have the effect that the guide slide laterally on the cylinder covers on the path g, 1z, i (see Fig. 3), the compression section, seal. - Such a seal does not take place on the suction section g, k, i , since the slides come out of the area of the contact surfaces due to the eccentricity of the piston drum and guide track and can move in the gap f. However, this is not of great importance since the pressure in the cells of the suction section is relatively low. The latter also relates to the losses due to the gap f. The contact surfaces e can also be replaced by particularly resilient insert plates.
Der Wellenhals .nebst Trommelringflächen m kann zur äußeren Abdichtung mitherangezogen werden.The shaft neck. Together with the drum ring surfaces m can be used for external sealing can also be used.
