Description

Anordnung der Laufbüchse bei Rotationsverdichtern Die Erfindung betrifft einen einwelligen Rotationsverdichter, insbesondere Vielzeilenverdichter, mit innerhalb des Verdichtergehäuses in Längsrichtung verlaufenden Rippen und dazwischen angeordneter Laufbüchse. Arrangement of the liner in rotary compressors The invention relates to a single-shaft rotary compressor, in particular a multi-row compressor, with ribs running in the longitudinal direction within the compressor housing and a liner arranged between them.

Bekannt ist eine Ausführung' bei welcher die Laufbüchse in das Verdichtergehäuse eingepreßt ist und sich hierbei längs des Gehäuseumfanges an Rippen abstützt. Die Rippen dienen einerseits zur Kraftaufnahme und haben andererseits die Aufgabe, die Abdichtung zwischen Saug-. und Druckseite zu übernehmen. Nachteilig bei dieser bekannten Ausführung ist die schwierige Innenbearbeitung des Gehäuses an den Stützrippen, wodurch die Herstel- lung einer genauen Preßpassung sehr aufwendig ist. Des weiteren muß die Außenoberfläche der Laufbüohse sehr genau bearbeitet sein, um eine gute Abdichtung zwischen Saug und Druckseite des Verdich- ters zu erreichen. Weiterhin nachteilig sind auftretende Wärmespannungen im Gehäuse und in der Büchse, welche Undichtigkeiten zwischen Saug-. und Druckseite des Verdichters zur Folge haben. An embodiment is known in which the liner is pressed into the compressor housing and is supported on ribs along the circumference of the housing. The ribs serve on the one hand to absorb force and on the other hand have the task of sealing between suction. and take over the print side. A disadvantage of this known embodiment is the difficult internal machining of the housing to the support ribs, whereby the manufacturing development of a precise interference fit is very expensive. Furthermore , the outer surface of the bushing must be machined very precisely in order to achieve a good seal between the suction and pressure side of the compressor . Another disadvantage are the thermal stresses occurring in the housing and in the sleeve, which are leaks between the suction. and pressure side of the compressor.

Der Erfindung liegt die Aufgabe zugrunde, unter Vermeidung dieser Nachteile eine einfache Anordnung der Laufbüchse mit sicherer Ab.. dichtung zwischen Saug., und Druckseite des Verdichters zu schaffen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lauf. büchse finit Spiel zu den Rippen eingelegt ist, stirnseitig durch am Verdichtergehäuse angeordnete Deckeln zentriert ist und zwischon Laufbüchse und Rippen je ein Dichtelement angeordnet ist. Von Vorteil ist hierbei, daß das Gehäuse ohne nachteillge Beeinflussung der Abdichtung aus-einem Werkstoff mit anderer Ausdehnungszahl als derjenigen des Werkstoffes von Laufbüchse und Deckei. bestehen kann. Des weiteren kann vorteilhafterweise die Laufbüchse von Hand ein.. und ausgebaut werden` Ein noch weiterer Vorteil ist die beliebige Längentoleranz der Lauf-büchse, weil die Abdichtung zwischen Trommel und Deckel im Gegensatz zu der bekannten Ausführung nicht mehr von der genauen Büchsenlänge abhängig ist. The invention is based on the object, while avoiding these disadvantages, a simple arrangement of the liner with a secure Ab .. seal between suction. , and to create the pressure side of the compressor. This object is achieved in that the barrel . Bushing finite clearance is inserted to the ribs, is centered on the front side by covers arranged on the compressor housing and a sealing element is arranged between the liner and the ribs. The advantage here is that the housing is made of a material with a different expansion coefficient than that of the material of the liner and cover, without adversely affecting the seal. can exist. Furthermore, the liner can advantageously be installed and removed by hand. Another advantage is the arbitrary length tolerance of the liner because, in contrast to the known design, the seal between drum and cover is no longer dependent on the exact liner length.

Zweokmäßigerweise sind die Rippen in Längsrichtung mit einer Ausnehmung zur Aufnahme des Dichtelementes versehen» T,Tobei das darin liegende Dichtelement aus einem mit Kunststoff oder mit einem anderen elastischen Werkstoff beschiohteten Roll1T besteht. Hiermit wird vorteilhafterweise das Rohr durch-den-Druckunterschied zwischen Lruck- und Saugseite fest gegen die Innenwand der Ausnehmung und die Laufbüchsenoberfläche gepreßtg wodurch stets eine sehr gute Abdichtung zwischen Saug-. und Druckseite des Verdichters gewährleistet ist, Durch -diese Anordnung des Dichtelementes steht die. Laufbüchse mit dem Verdichtergehäuse nicht direkt in Verbindung' womit vorteilhafterweise eine ge## räuschdämpfende Wirkung erzielt wird, Die Zeichnung veranschaulicht ein Ausführungsbeispiel der' Erfindung, es zeigen Fig.1 einen Querschnitt und.Suitably, the ribs are provided in the longitudinal direction with a recess for receiving the sealing element, where the sealing element located therein consists of a roller coated with plastic or another elastic material. In this way, the pipe is advantageously pressed firmly against the inner wall of the recess and the liner surface due to the pressure difference between the pressure side and the suction side, whereby a very good seal between the suction side is always achieved. and pressure side of the compressor is guaranteed. The liner is not directly connected to the compressor housing, which advantageously has a noise-damping effect. The drawing illustrates an embodiment of the invention, FIG. 1 shows a cross section and FIG.

Durch einen oder mehrere im Deckel 10 befestigte Stifte 12 ist die Laufbüchse 7 gegen Verdrehung gesichert, Zwischen der Laufbüchse 7 und den Ausnehmungen 6,62 der Rippen 4 und ist jeweils ein mit .Kunststoff oder einem anderen elasti- schen Verkstoff besohiohtetes Rohr 13 einerseits fest dicht gegen die Ausnehmung 6 bzw, 61 und adererseits gegen die Laufbüchse 7 ?epreßte Die Gaskräfte dur Laufbüchse 7 werden über die Asst. se 11 der Deckel 10 auf das Verdichtergehä.use 1 übertrageneIn the compressor housing 1 with the suction channel 2 and the pressure channel 3 , two ribs 4 and 5 are arranged opposite one another.
