Aufgabe der vorliegenden Erfindung ist es, einen Verdichterflansch zur Verbindung eines Schraubenverdichters mit einem Antrieb bereitzustellen, der einen geringen Fertigungs- und Montageaufwand erfordert und mehrere Funktionen in einem Bauteil vereint. The object of the present invention is to provide a compressor flange for connecting a screw compressor with a drive, which requires little manufacturing and assembly work and combines several functions in one component.
Die Aufgabe wird gelöst durch einen Verdichterflansch mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung werden in den auf Anspruch 1 direkt oder indirekt rückbezogenen Unteransprüchen angegeben. Des Weiteren wird ein Schraubenverdichter mit einem solchen Verdichterflansch zur Lösung der Aufgabe vorgeschlagen. The object is achieved by a compressor flange with the features of claim 1. Advantageous developments of the invention are specified in the dependent claim 1 directly or indirectly dependent claims. Furthermore, a screw compressor with such a compressor flange is proposed for achieving the object.
Offenbarung der Erfindung Der angegebene Verdichterflansch zur Verbindung eines Schraubenverdichters mit einem Antrieb weist eine zentrale Öffnung zur Aufnahme einer Welle und/oder eines Lagers auf und besitzt eine erste ringförmige Anlagefläche zur Anlage an einem Gehäuse des Verdichters und eine zweite ringförmige Anlagefläche zur Anlage an einem Gehäuse des Antriebs. Erfindungsgemäß umfasst der Verdichterflansch ferner axial und/oder radial wirksame Dichtungen zur Abdichtung gegenüber dem Verdichtergehäuse und/oder der Welle, so dass ein offenes Verdichtergehäuse durch Einsatz des Verdichterflansches verschließbar und abdichtbar ist. Die Dichtungen bilden Bestandteile des Verbindungsflansches aus, so dass der Einsatz separater Dichtmittel, die getrennt vom Flanschbauteil montiert werden müssen, nicht erforderlich ist. Der Verdichterflansch übernimmt somit gleichzeitig die Funktion eines Stirndeckels, der üblicherweise zum Verschließen und Abdichten eines Schraubenverdichters vorgesehen ist. D.h., der Verdichterflansch übernimmt neben der Verbindungsfunktion auch eine Verschluss- und eine Abdichtungsfunktion. Die Anzahl der erforderlichen Bauteile kann demnach reduziert werden, so dass folglich auch der Fertigungs- und der Montageaufwand verringert werden. DISCLOSURE OF THE INVENTION The stated compressor flange for connecting a screw compressor to a drive has a central opening for receiving a shaft and / or a bearing and has a first annular contact surface for engagement with a housing of the compressor and a second annular contact surface for engagement with a housing of the drive. According to the invention, the compressor flange further comprises axially and / or radially effective seals for sealing against the Compressor housing and / or the shaft, so that an open compressor housing by use of the compressor flange is closed and sealed. The seals form components of the connecting flange, so that the use of separate sealing means, which must be mounted separately from the flange, is not required. The compressor flange thus simultaneously assumes the function of an end cover, which is usually provided for closing and sealing a screw compressor. This means that the compressor flange not only performs the connection function but also a closing and sealing function. The number of required components can therefore be reduced, so that consequently the manufacturing and assembly costs are reduced.
Die axial und/oder radial wirksamen Dichtungen können in Nuten am The axially and / or radially effective seals can in grooves on
Verdichterflansch eingesetzt oder angespritzt bzw. angeformt sein. Vorzugsweise erfolgt die Abdichtung gegenüber der Welle im Bereich des Lagers der Welle, so dass die Dichtung keiner dynamischen Belastung ausgesetzt ist. Die Dichtung weist somit eine hohe Lebensdauer auf. Compressor flange used or molded or molded. Preferably, the seal against the shaft in the region of the bearing of the shaft, so that the seal is not exposed to dynamic stress. The seal thus has a long service life.
Bevorzugt ist ferner vorgesehen, dass der Verdichterflansch eine axial wirksame Dichtung zur Abdichtung gegenüber dem Gehäuse des Antriebs besitzt. Somit ist auch ein dichter Anschluss des Schraubenverdichters am Gehäuse des Antriebs gewährleistet. Preferably, it is further provided that the compressor flange has an axially effective seal for sealing against the housing of the drive. Thus, a tight connection of the screw compressor is ensured on the housing of the drive.
Des Weiteren bevorzugt ist eine Ringstufe an wenigstens einer Stirnfläche des Verdichterflansches zur Zentrierung des Verdichterflansches in Bezug auf das Verdichtergehäuse, die Welle, das Lager und/oder das Gehäuse des Antriebs ausgebildet. Somit weist der Verdichterflansch zugleich eine Zentrierfunktion auf und macht weitere Verbindungselemente, beispielsweise in Form von Zentrierstiften, entbehrlich. Vorzugsweise ist an beiden Stirnflächen des Verdichterflansches jeweils eine Ringstufe zur Zentrierung gegenüber dem Verdichtergehäuse und dem Antrieb ausgebildet. Vorteilhafterweise ist an der dem Verdichtergehäuse zugewandten Stirnfläche ein axialer Ansatz zur axialen Lagefixierung des Lagers ausgebildet. D.h., dass nach Verbindung des Verdichterflansches mit dem Verdichtergehäuse der axiale Ansatz an einer radial verlaufenden Fläche des Lagers abgestützt ist. Der axiale Ansatz kann ferner derart ausgebildet sein, dass er eine verdichterseitig angeordnete Ringstufe zur Zentrierung ersetzt. Hierzu ist der axiale Ansatz vorzugsweise derart in eine am Verdichtergehäuse oder dem Lager ausgebildete Ausnehmung einsetzbar, das der axiale Ansatz nicht nur axial, sondern auch radial abgestützt ist. Der axiale Ansatz am Verdichterflansch erfüllt auf diese Weise eine Halte- und eine Zentrierfunktion. Further preferably, an annular step is formed on at least one end face of the compressor flange for centering the compressor flange with respect to the compressor housing, the shaft, the bearing and / or the housing of the drive. Thus, the compressor flange at the same time has a centering function and makes additional connecting elements, for example in the form of centering pins, dispensable. Preferably, an annular step for centering with respect to the compressor housing and the drive is formed on both end faces of the compressor flange. Advantageously, an axial projection for axially fixing the position of the bearing is formed on the end facing the compressor housing. That is, after connection of the compressor flange with the compressor housing, the axial projection is supported on a radially extending surface of the bearing. The axial projection can also be designed in such a way that it replaces a ring stage arranged on the compressor side for centering. For this purpose, the axial projection is preferably used in such a manner formed in a recess formed on the compressor housing or the bearing, which is not only axially, but also radially supported the axial approach. The axial approach to the compressor in this way fulfills a holding and a centering function.
Alternativ kann auch der Flansch eine Ringstufe in der Form aufweisen, dass diese die Mantelfläche des Wellenlagers aufnimmt und dessen axiale Position fixiert. Hierdurch wird auch eine Zentrierung des Flansches am Lager erreicht. Letzteres kann dadurch erreicht werden, dass das Lagerende axial über das Verdichtergehäuse herausragt oder dadurch, dass das Verdichtergehäuse eine entsprechende Alternatively, the flange may have an annular step in the form that it receives the lateral surface of the shaft bearing and fixes its axial position. As a result, a centering of the flange is reached at the camp. The latter can be achieved in that the bearing end protrudes axially beyond the compressor housing or in that the compressor housing a corresponding
Ausnehmung aufweist. Has recess.
Der Verdichterflansch ist vorzugsweise mittels Schrauben am Verdichtergehäuse befestigbar. Hierzu sind im Bereich der ersten ringförmigen Anlagefläche zur Anlage des Verdichterflansches am Verdichtergehäuse Bohrungen zur Aufnahme der Schrauben vorgesehen. The compressor flange can preferably be fastened by means of screws to the compressor housing. For this purpose, bores for receiving the screws are provided in the region of the first annular abutment surface for abutment of the compressor flange on the compressor housing.
Gemäß einem bevorzugten Ausführungsbeispiel ist der Verdichterflansch topfförmig ausgebildet und begrenzt in Anlage am Verdichtergehäuse und am Gehäuse des Antriebs einen Hohlraum zur Aufnahme einer Kupplung, welche die Welle des Verdichters mit einer Welle des Antriebs verbindet. Die Einhausung der Kupplung durch den Verdichterflansch ermöglicht den Wegfall einer Kupplungsglocke und damit den Einsatz einer einfachen Kupplung. Somit kann die Anzahl der Bauteil weiter reduziert werden. Ferner verringert sich der Platzbedarf, aufgrund der geringeren Gesamtbaugröße. Schließlich kann auch Gewicht eingespart werden. According to a preferred embodiment, the compressor flange is pot-shaped and limited in contact with the compressor housing and the housing of the drive has a cavity for receiving a coupling which connects the shaft of the compressor with a shaft of the drive. The housing of the coupling through the compressor flange allows the elimination of a clutch bell and thus the use of a simple coupling. Thus, the number of component be further reduced. Furthermore, the space requirement is reduced due to the smaller overall size. Finally, weight can be saved.
Mit einer Reduzierung der Anzahl der Bauteile geht ferner ein reduzierter With a reduction in the number of components is also a reduced
Montageaufwand einher, da weniger Bauteile zueinander ausgerichtet und miteinander befestigt werden müssen. Zudem reduzieren sich die Stellen, die zusätzlich abgedichtet werden müssen. Auch eine Aufsummierung von Fertigungsund/oder Montagetoleranzen wird hierdurch sicher vermieden. Die am Verdichterfiansch vorgesehenen Dichtungen gewährleisten auch bei Wegfall einer Kupplungsglocke, dass die im Hohlraum des topfförmigen Verdichterflansches aufgenommene Kupplung ausreichend geschützt ist. Dieser Schutz kann auch gewährleistet werden, wenn beispielsweise der Einsatz des Schraubenverdichters in teilweise eingetauchtem Betrieb erfolgt. Des Weiteren kann der Hohlraum zur Aufnahme eines Schmiermediums dienen, da über die Dichtungen des Assembly costs associated with fewer components aligned with each other and must be secured together. In addition, the places that need to be additionally sealed are reduced. Even a summation of manufacturing and / or assembly tolerances is thereby safely avoided. The seals provided on the compressor flange ensure, even if a clutch bell is removed, that the coupling received in the cavity of the cup-shaped compressor flange is sufficiently protected. This protection can also be ensured if, for example, the screw compressor is used in partially submerged operation. Furthermore, the cavity can serve to receive a lubricant, since the seals of the
Verdichterfiansches sichergestellt ist, dass kein Schmiermedium nach außen gelangt. Sofern im Bereich der Welle eine Schmiermittelleckage auftreten sollte, dient der Hohlraum des topfförmigen Verdichterflansches dem Auffangen des ausgetretenen Schmiermittels.  It is ensured by the compressor that no lubricating medium escapes to the outside. If a lubricant leakage should occur in the area of the shaft, the cavity of the cup-shaped compressor flange serves to catch the leaked lubricant.
Vorzugsweise bildet die Stirnfläche im Bereich des Bodens des topfförmigen Verdichterfiansches die erste ringförmige Anlagefläche zur Anlage des Preferably, the end face forms in the region of the bottom of the pot-shaped compressor Fiansches the first annular contact surface for conditioning of the
Verdichterfiansches am Verdichtergehäuse aus. Somit kann in einfacher Weise die Deckelfunktion des Verdichterfiansches realisiert werden. Die zentrale Öffnung zur Aufnahme der Welle ist ebenfalls im Bereich des Bodens des topfförmigen Compressor fins on the compressor housing off. Thus, the cover function of the compressor fins can be realized in a simple manner. The central opening for receiving the shaft is also in the area of the bottom of the cup-shaped
Verdichterfiansches vorgesehen. Weiterhin vorzugsweise bildet die den Hohlraum radial begrenzende und dem Boden des topfförmigen Verdichterfiansches gegenüberliegende Stirnfläche die zweite ringförmige Anlagefläche zur Anlage des Verdichterfiansches am Gehäuse des Antriebs aus. Zur Wartung und/oder zur Entlüftung des Schraubenverdichters kann der Compressor finssches provided. Further preferably, the cavity radially delimiting and the bottom of the cup-shaped Verdichterfiansches opposite end face forms the second annular contact surface for abutment of the Kompressorfiansches on the housing of the drive. For maintenance and / or ventilation of the screw compressor, the
Verdichterflansch ferner Öffnungen, insbesondere Wartungs- und/oder Compressor flange further openings, in particular maintenance and / or
Entlüftungsöffnungen, besitzen. Diese sind vorzugsweise derart ausgebildet, dass die Dichtfunktion des Verdichterflansches gewährleistet bleibt. Vents, own. These are preferably designed such that the sealing function of the compressor flange is ensured.
Zur Lösung der Aufgabe wird ferner ein Schraubenverdichter mit einem To solve the problem is also a screw compressor with a
erfindungsgemäßen Verdichterflansch vorgeschlagen, wobei der Verdichterflansch zugleich als Stirndeckel zum Verschließen und Abdichten des Verdichtergehäuses und als Verbindungsflansch zur Verbindung des Verdichtergehäuses mit dem proposed compressor flange according to the invention, wherein the compressor flange at the same time as an end cover for closing and sealing the compressor housing and as a connecting flange for connecting the compressor housing with the
Gehäuse des Antriebes dient. Dabei kann der vom Verdichterflansch umschlossene Raum - in Abhängigkeit von den Anforderungen der verwendeten Kupplungsart, der Art der Wellenverbindung oder weiteren sich aus der Anwendung ergebenden Anforderungen - als offener oder geschlossener Verdichter ausgeführt sein. Eine bevorzugte Ausführungsform der Erfindung wird nachfolgend anhand der einzigen Figur näher erläutert. Diese zeigt einen erfindungsgemäßen Housing of the drive is used.
