Definitions
- the invention relates to a side channel compressor according to the preamble of claim 1.
- Such a side channel compressor is known from DE-U-77 10 288.
- this known compressor several fastening points are provided distributed over the outer circumference of the housing, to which a base part formed from sheet metal can be fastened by means of screws.
- the foot part itself has fastening tabs projecting laterally over the fastening points on the compressor housing, with which it can be fastened to a mounting surface at the installation location of the compressor.
- the known compressor can only be set up with an axis that is horizontal relative to the mounting surface due to the fastening points provided on the outer circumference of its housing.
- the invention is based on the object of designing a side channel compressor of the generic type in such a way that it can be set up with an axis which is perpendicular to the mounting surface.
- tubular feet are provided as fastening points at least on the outer circumference of the housing half facing away from the drive motor and have a radially projecting stop shoulder for a fastening element in their cavity. Due to the arrangement of the fastening points on the outer circumference on the one hand, there is good accessibility to these points, so that the fastening of the compressor at the installation site is made much easier. On the other hand, the force is introduced into the fastening points in a relatively short way via the outer regions of the housing halves, so that in particular the hub region is kept free of loads which could lead to an impairment of the narrow gaps existing in this region in the case of a side channel compressor. Fastening screws can be passed through the hollow feet and their screw heads rest on the radially projecting stop shoulder and thus hold the housing.
- tubular feet are integrally formed on both housing halves, a similar design of the two housing halves is possible.
- a perfectly identical design of both housing halves results from the fact that the feet are arranged symmetrically with respect to an axial bisection line of the housing halves and are also shaped symmetrically with respect to this halving line.
- a sealing of both housing halves without separate sealing means with identical design of the housing halves is possible in that on the front peripheral edge of the inner front side of each housing half a sealing lip extending on one side of the bisecting line over one circumferential half of the front side and on the other side of the bisecting line extending sealing groove is formed over the other circumferential half.
- the housing of a side channel compressor consisting of two housing halves 2 and 3 is designated.
- a drive motor 4 is flanged onto one end of the housing.
- a muffler part 7 having an inlet and an outlet opening 5 and 6 is arranged below the drive motor.
- Certain eyes 9 are provided on the outer circumference of the housing halves 2 and 3 for receiving connecting screws 8.
- three tubular feet 10 are integrally formed on the outer circumference of the housing halves 2 and 3. The feet 10 protrude at least slightly in the axial direction relative to the plane 11 of the end face of the housing halves 2 and 3, so that when the compressor unit is installed with a vertical axis, the compressor housing 1 rests with the feet 10 on the installation surface.
- a stop shoulder 13 projecting radially inward is formed in the cavity 12 of the feet 10. On this stop shoulder 13, screws serving to fasten the compressor unit at its installation site rest with their screw heads.
- feet 10 would only be required for fastening the compressor unit on one housing half 2 facing away from the drive motor 4, they are also provided on the other housing half 3.
- the feet 10 are also symmetrical to an axially extending bisecting plane of the Housing halves 2 and 3 arranged and formed symmetrically to this plane when divided by this plane. So that both housing halves 2 and 3 can be made completely identical in terms of their outline.
- openings 14 are provided as knockouts 15 on both housing halves 2 and 3 and are only opened on the other housing half 3.
- the sealing of the two housing halves 2 and 3 takes place via a sealing lip 17 which is provided on the front peripheral edge 16 of the inner end face of each housing half 2 and 3 and extends over the one circumferential half of the end face and engages in a sealing groove 18 which extends over the other circumferential half.
- the extension of the sealing lip 17 and the sealing groove 18 over half the circumference on both sides of the bisecting plane symmetrically dividing the housing halves in turn enables the housing halves 2 and 3 to be designed identically.

Abstract
Description
Die Erfindung betrifft einen Seitenkanalverdichter gemäß dem Oberbegriff des Anspruches 1.The invention relates to a side channel compressor according to the preamble of
Ein solcher Seitenkanalverdichter ist durch das DE-U-77 10 288 bekannt. Bei diesem bekannten Verdichter sind über dem Außenumfang des Gehäuses verteilt mehrere Befestigungsstellen vorgesehen, an denen mittels Schrauben ein aus Blech geformtes Fußteil befestigt werden kann. Das Fußteil selbst weist über die Befestigungsstellen am Verdichtergehäuse seitlich überstehende Befestigungslaschen auf, mit denen es am Aufstellort des Verdichters auf einer Aufstellfläche befestigt werden kann. Der bekannte Verdichter kann aufgrund der am Außenumfang seines Gehäuses vorgesehenen Befestigungsstellen nur mit gegenüber der Aufstellfläche waagerechter Achse aufgestellt werden. Es gibt jedoch häufig auch Anwendungsfälle, die eine Aufstellung des Verdichters mit gegenüber der Aufstellfläche senkrechter Achse erfordern.Such a side channel compressor is known from DE-U-77 10 288. In this known compressor, several fastening points are provided distributed over the outer circumference of the housing, to which a base part formed from sheet metal can be fastened by means of screws. The foot part itself has fastening tabs projecting laterally over the fastening points on the compressor housing, with which it can be fastened to a mounting surface at the installation location of the compressor. The known compressor can only be set up with an axis that is horizontal relative to the mounting surface due to the fastening points provided on the outer circumference of its housing. However, there are often applications that require the compressor to be installed with an axis perpendicular to the installation surface.
Der Erfindung liegt die Aufgabe zugrunde, einen Seitenkanalverdichter der gattungsgemäßen Art so auszubilden, daß dieser mit gegenüber der Aufstellfläche senkrecht gerichteter Achse aufgestellt werden kann.The invention is based on the object of designing a side channel compressor of the generic type in such a way that it can be set up with an axis which is perpendicular to the mounting surface.
Die Losung der gestellten Aufgabe gelingt durch die in Kennzeichen des Anspruches 1 angegebenen Merkmale.The solution to the problem is achieved by the features specified in the characterizing part of
Gemäß einer vorteilhaften Weiterbildung der Erfindung sind zumindest am Außenumfang der dem Antriebsmotor abgewandten Gehäusehälfte als Befestigungsstellen rohrförmige Füße vorgesehen, die in ihrem Hohlraum eine radial vorspringende Anschlagschulter für ein Befestigungselement aufweisen. Durch die Anordnung der Befestigungsstellen am Außenumfang ist einerseits eine gute Zugänglichkeit dieser Stellen gegeben, so daß hierdurch das Befestigen des Verdichters am Aufstellort sehr erleichtert wird. Andererseits erfolgt die Krafteinleitung in die Befestigungsstellen auf relativ kurzem Wege über die Außenbereiche der Gehäusehälften, so daß insbesondere der Nabenbereich von Belastungen freigehalten wird, die zu einer Beeinträchtigung der in diesem Bereich bei einem Seitenkanalverdichter bestehenden engen Spalte führen könnten. Durch die hohl ausgebildeten Füße können Befestigungsschrauben hindurchgeführt werden, welche mit ihrem Schraubenkopf auf der radial vorspringenden Anschlagschulter aufliegen und damit das Gehäuse halten.According to an advantageous development of the invention, tubular feet are provided as fastening points at least on the outer circumference of the housing half facing away from the drive motor and have a radially projecting stop shoulder for a fastening element in their cavity. Due to the arrangement of the fastening points on the outer circumference on the one hand, there is good accessibility to these points, so that the fastening of the compressor at the installation site is made much easier. On the other hand, the force is introduced into the fastening points in a relatively short way via the outer regions of the housing halves, so that in particular the hub region is kept free of loads which could lead to an impairment of the narrow gaps existing in this region in the case of a side channel compressor. Fastening screws can be passed through the hollow feet and their screw heads rest on the radially projecting stop shoulder and thus hold the housing.
Dadurch, daß an beiden Gehäusehälften rohrförmige Füße einteilig angeformt sind, ist eine gleichartige Ausbildung der beiden Gehäusehälften möglich.Characterized in that tubular feet are integrally formed on both housing halves, a similar design of the two housing halves is possible.
Eine vollkommene identische Ausbildung beider Gehäusehälften ergibt sich dadurch, daß die Füße symmetrisch zu einer axialen Halbierungslinie der Gehäusehälften angeordnet und ebenfalls symmetrisch in bezug auf diese Halbierungslinie geformt sind.A perfectly identical design of both housing halves results from the fact that the feet are arranged symmetrically with respect to an axial bisection line of the housing halves and are also shaped symmetrically with respect to this halving line.
Eine Abdichtung beider Gehäusehälften ohne gesonderte Dichtungsmittel bei identischer Ausbildung der Gehäusehälften ist dadurch möglich, daß an der stirnseitigen Umlaufkante der inneren Stirnseite jeder Gehäusehälfte eine sich auf der einen Seite der Halbierungslinie über die eine Umfangshälfte der Stirnseite erstreckende Dichtlippe und auf der anderen Seite der Halbierungslinie eine sich über die andere Umfangshälfte erstreckende Dichtnut ausgebildet ist.A sealing of both housing halves without separate sealing means with identical design of the housing halves is possible in that on the front peripheral edge of the inner front side of each housing half a sealing lip extending on one side of the bisecting line over one circumferential half of the front side and on the other side of the bisecting line extending sealing groove is formed over the other circumferential half.
Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung nachfolgend näher beschrieben.
Es zeigt:

Mit 1 ist das aus zwei Gehäusehälften 2 und 3 bestehende Gehäuse eines Seitenkanalverdichters bezeichnet. Auf der einen Gehäusestirnseite ist ein Antriebsmotor 4 angeflanscht. Unterhalb des Antriebsmotors ist ein eine Ein- und eine Auslaßöffnung 5 und 6 aufweisendes Schalldämpferteil 7 angeordnet.With 1, the housing of a side channel compressor consisting of two
Am Außenumfang der Gehäusehälften 2 und 3 sind zur Aufnahme von Verbindungsschrauben 8 bestimmte Augen 9 vorgesehen. Außerdem sind am Außenumfang der Gehäusehälften 2 und 3 drei rohrförmige Füße 10 einteilig angeformt. Die Füße 10 ragen in axialer Richtung gegenüber der Ebene 11 der Stirnseite der Gehäusehälften 2 und 3 zumindest geringfügig vor, so daß bei einer Aufstellung des Verdichteraggregates mit senkrechter Achse das Verdichtergehäuse 1 mit den Füßen 10 auf der Aufstellfläche aufruht.
In dem Hohlraum 12 der Füße 10 ist eine nach radial innen vorspringende Anschlagschulter 13 ausgebildet. Auf dieser Anschlagschulter 13 ruhen zur Befestigung des Verdichteraggregates an seinem Aufstellort dienende Schrauben mit ihrem Schraubenkopf auf.A
Obwohl die Füße 10 für die Befestigung des Verdichteraggregates nur an der einen, dem Antriebsmotor 4 abgewandten Gehäusehälfte 2 erforderlich wären, sind diese auch an der anderen Gehäusehälfte 3 vorgesehen. Die Füße 10 sind ferner symmetrisch zu einer sich axial erstreckenden Halbierungsebene der Gehäusehälften 2 und 3 angeordnet und bei einer Teilung durch diese Ebene symmetrisch zu dieser Ebene geformt. Damit können beide Gehäusehälften 2 und 3 von ihrem Umriß her vollkommen identisch ausgeführt werden. An der anderen Gehäusehälfte 3 für die Verbindung mit dem Antriebsmotor 4 notwendige Durchbrüche 14 sind als Vorprägungen 15 an beiden Gehäusehälften 2 und 3 vorgesehen und werden lediglich an der anderen Gehäusehälfte 3 geöffnet.Although the
Die Abdichtung der beiden Gehäusehälften 2 und 3 erfolgt über eine an der stirnseitigen Umlaufkante 16 der inneren Stirnseite jeder Gehäusehälfte 2 und 3 vorgesehene, sich über die eine Umfangshälfte der Stirnseite erstreckende Dichtlippe 17, die in eine sich über die andere Umfangshälfte erstreckende Dichtnut 18 eingreift. Die Erstreckung der Dichtlippe 17 und der Dichtnut 18 jeweils über den halben Umfang zu beiden Seiten der die Gehäusehälften symmetrisch teilenden Halbierungsebene ermöglicht wiederum eine identische Ausbildung der Gehäusehälften 2 und 3.The sealing of the two
