Description

Drehkolbenmaschine, insbesondere Verdichter, mit in der Kolbentrommel und deren seitlichen Dichtungsscheiben verschiebbaren Kolben. Die Erfindung ist eine Lösung der Aufgabe, die Führungsschlitze der Kolben von Drehkolbenmaschinen in der Kolbentrommel und in den seitlichen Dichtungsscheiben gemeinsam so herzustellen, daß ein klemmungsfreies Gleiten der Kolben erreicht wird.Rotary piston machine, in particular compressor, with in the piston drum and their lateral sealing washers displaceable pistons. The invention is a solution to the problem, the guide slots of the pistons of rotary piston machines in the piston drum and in the side sealing washers together in such a way that that a jam-free sliding of the piston is achieved.

Im allge'meine'n sind die Kolbentrommel und die Dichtungsscheiben aus einem Stück angefertigt. Aus diesem Grunde müssen die Langlöcher, die zur Aufnahme der Schieberkolben dienen, in sehr zeitraubender und kostspieliger Weise mittels Finger- oder Sc@aftfräser eingearbeitet werden. Abgesehen davon, daß diese Art der Bearbeitung nur möglich ist, wenn es sich um verhältnismäßig größere. Maschinen mit breiten (starken) Kolben von etwa to mm handelt, ist es nicht möglich, solche Langlöcher unter 3 mm Breite auszuführen. Schmale Langlöcher sind aber bei solchen Maschinen, die als Verdichter, Gebläse o. dgl. verwendet werden, unbedingt erforderlich. Bis jetzt war es daher nicht möglich, solche Langlöcher in. die Kolbentrommel, die mit den seitlichen Dichtungsscheiben aus einem Stück bestehen, herzustellen.In general, the piston drum and the sealing washers are made from one piece. For this reason, the elongated holes that are used for receiving the spool serve in a very time consuming and costly manner by means of End mills or milling cutters can be incorporated. Besides being this kind of Processing is only possible if it is relatively larger. machinery with wide (strong) pistons of about to mm, it is not possible to do such Make elongated holes less than 3 mm wide. However, there are narrow elongated holes in such Machines that are used as compressors, blowers or the like are absolutely necessary. Until now it was therefore not possible to make such elongated holes in the piston drum, which consist of one piece with the side sealing washers.

Die vorliegende Neuerung ermöglicht aber in einwandfreier Weise die Herstellung derartig schmaler Langlöcher. Das Verfahren besteht darin, daß in der Kolbentrommel und den Dichtungsscheiben die Führungsschlitze beispielsweise mittels Scheibenfräsers glatt durchgefräst und seitlich die Wellen mit je einem entsprechenden Flansch versehen werden, der die Dichtungsscheiben umschließt und der mittels Schrauben mit der Trommel 'fest verbunden wird, so daß Welle, Trommel und Dichtungsscheiben ein festes Gefüge bilden.The present innovation enables the perfect way Production of such narrow elongated holes. The method consists in that in the Piston drum and the sealing washers, for example, by means of the guide slots The side milling cutter is milled through smoothly and the shafts each with a corresponding one Flange are provided that surrounds the sealing washers and that by means of screws with the drum 'is firmly connected, so that shaft, drum and Sealing washers form a solid structure.

Auf der Zeichnung ist die Erfindung dargestellt. -Es zeigt Abb. z einen Querschnitt nach AAB der Abb. a, Abb. z einen Längsschnitt und Abb.3 einen Querschnitt nach GLDD der Abb. a, wobei das Gehäuse fortgelassen ist. In dem Gehäuse a befindet sich die Kolbentrommel b mit den seitlichen Dichtungsscheiben c, c'. Diese werden von den Wellenflanschen d, d' umschlossen und mittels Schrauben e fest mit denselben verbunden. Die Kolben f werden in den Führungsschlitzen g, die über die Gesamtlänge der Trommel und Dichtungsscheiben verlaufen, geführt. Der Abschluß der durchlaufenden Führungsschlitze g erfolgt durch die sie umschließenden Wellenflanschen d, d'. Die Führungsschlitze können durch die Einrichtung bis auf o,5 mm herab ausgeführt werden, wodurch es ermöglicht ist, annähernd masselose Schieberkolben zu verwenden. Derartige Schieber sind von großer wirtschaftlicher Bedeutung für Rundlaufverdichter o..dgl., bei denen hohe Drehzahlen verwendet werden.The invention is shown in the drawing. -It shows fig a cross-section according to AAB of Fig. a, Fig. z is a longitudinal section and Fig. 3 is a Cross-section according to GLDD of Fig. A, with the housing omitted. In the case a is the piston drum b with the side sealing washers c, c '. These are enclosed by the shaft flanges d, d 'and fixed by means of screws e connected to the same. The pistons f are in the guide slots g, which over run the entire length of the drum and sealing washers, guided. The conclusion the continuous guide slots g takes place through the shaft flanges surrounding them d, d '. The guide slots can be made down to 0.5 mm through the device which makes it possible to use approximately massless slide pistons. Such slides are of great economic importance for rotary compressors or the like, where high speeds are used.
