Description

Maschine mit umlaufenden Kolben, seitlichen Dichtungsscheiben an der Kolbentrommel und ungeteiltem Gehäuse. Es sind Maschinen mit umlaufenden Kolben und seitlichen Dichtungsscheiben an der Kolbentrommel bekannt, bei denen das Maschinengehäuse aus zwei Hälften besteht. Das Unterteilen des Maschinengehäuses bietet in der Ausführung sehr große Schwierigkeiten. Insbesondere ist die Anordnung einwandfreier Ein- und Auslaßkanäle, die ein stoßfreies Cbergleitetl der Schieberkolben ermöglichen, nicht zu erreichen. Ein weiterer Nachteil des unterteilten Gehäuses liegt darin, daß die Beanspruchung der Zylinderhälften sowie die Dehnung derselben ein dichtes Arbeiten der umlaufenden Teile verhindern.Machine with rotating pistons, sealing washers on the side Piston drum and undivided housing. They are machines with rotating pistons and lateral sealing washers on the piston drum known, in which the machine housing consists of two halves. The subdivision of the machine housing offers in the execution very big trouble. In particular, the arrangement is flawless input and Outlet channels that allow the slide pistons to slide smoothly over and over again do not to reach. Another disadvantage of the divided housing is that the The stress on the cylinder halves and the stretching of the same result in tight work prevent the rotating parts.

Diese Übelstände zu beseitigen, bezweckt die vorliegende Neuerung, die darin besteht, daß eine an sich bekannte, besondere Laufbuchse, die aber aus zwei Hälften besteht, die Kolbentrommel und Dichtungsscheiben umschließt und in ein aus einem Stück hergestelltes Maschinengehäuse eingesetzt wird. Das Unterteilen der Laufbuchse hat also den Zweck, daß sowohl die Kolbentrommel mit den seitlichen Dichtungsscheiben als auch das Maschinengehäuse je aus einem Stück hergestellt werden können, so daß bei denkbar kleinsten Abmessungen, z. B. bei Benutzung der Maschine als Pumpe, große Förderleistung und große Drücke erzielt «-erden. Die Laufbuchse ist hierbei derart gestaltet, daß die Kolbentrommel mit den seitlichen Dichtungsscheiben dicht und einwandfrei im Betriebe arbeiten kann. Ferner ermöglicht die unterteilte Laufbuchse die Anordnung einwandfreier Saug- und Druckkanäle. Die Saug- und Druckkanäle sind in diesem Fall in an sich bekannter Weise schräg angeordnet, so daß die umlaufenden Schieberkolben gleichmäßig schleifend an den Steuerkanälen vorbeigleiten. Desgleichen ermöglicht diese Einrichtung eine hinreichende Größenbemessung der Kanäle und den Fortfall von Luftsäcken. Ein wichtiger Vorteil der unterteilten Laufbuchse liegt darin, daß deren Herstellung erheblich einfacher als die Herstellung des zweiteiligen Gehäuses ist. Ebenso wichtig ist, daß es bei eintretendem Verschleiß ohne weiteres möglich ist, die Laufbuchse sehr schnell auszuwechseln.The aim of the present innovation is to eliminate these shortcomings, which is that a known, special liner, but from consists of two halves, enclosing the piston barrel and sealing washers and in a machine housing made from one piece is used. The dividing The purpose of the liner is that both the piston drum and the lateral Sealing washers as well as the machine housing are each made from one piece can, so that with the smallest possible dimensions, z. B. when using the machine as a pump, high delivery capacity and high pressures achieved «-erden. The liner is designed in such a way that the piston drum with the lateral sealing washers can work tightly and properly in the company. Furthermore, the subdivided Liner the arrangement of perfect suction and pressure channels. The suction and pressure channels are inclined in this case in a known manner, so that the circumferential Slide spool smoothly past the control channels. Likewise this facility enables the ducts and the Elimination of air sacs. An important advantage of the subdivided cylinder liner is in that their production is much easier than the production of the two-part Housing is. It is just as important that it is readily available when wear and tear occurs it is possible to change the liner very quickly.

In der Zeichnung ist in Abb. I ein Längsschnitt durch die Laufbuchse, Abb. a ein Querschnitt durch die Laufbuchse, Abb.3 eine Ansicht der Laufbuchse, Abb. 4. ein Längsschnitt und Abb.5 ein Querschnitt durch die ganze Maschine dargestellt.In the drawing, Fig. I shows a longitudinal section through the liner, Fig. A is a cross-section through the liner, Fig. 3 is a view of the liner, Fig. 4 shows a longitudinal section and Fig. 5 shows a cross section through the entire machine.

In dem Gehäuse a. ist die zweiteilige Laufbuchse b-b" mit der Kolbentrommel c und den seitlichen Dichtungsscheiben d-dl sowie den in der Kolbentrommel c befindlichen Schieberkolben e angeordnet. Die beiden Teile der Laufbuchse b werden durch die Schrauben f und g verschraubt und durch die Stellschraube h in ihre Lage im Gehäuse a. gehalten. Die Druck- und Saugkanäle h-rral sind in der Laufbuchse b angebracht und münden unmittelbar in die Saug- und Druckanschlüsse 1-in des Gehäuses.In the housing a. the two-part bushing bb ″ with the piston drum c and the lateral sealing washers d-dl and the slide piston e located in the piston drum c are arranged. The two parts of the bushing b are screwed together by the screws f and g and in their position by the adjusting screw h . retained in the housing a. the pressure and suction channels h-rral b are mounted in the bushing and open directly into the suction and pressure ports 1 in the housing.
