Description

Die Erfindung bezieht sich auf ein aus zwei Gehäusehälften bestehendes Gehäuse für einen Seitenkanalverdichter, mit zwei an der Frontwand jeder Gehäusehälfte radial voneinander beabstandeten, gegenüber der Frontwand axial vorstehenden Ringen.The invention relates to one of two housing halves existing housing for a side channel blower, with two radially spaced from each other on the front wall of each housing half, rings protruding axially from the front wall.

Die US-Schrift US-A-3,915,589 zeigt das Gehäuse eines Seitenkanalverdichters, der in Umfangsrichtung radial angeordnete Kühlrippen aufweist.The US document US-A-3,915,589 shows the housing of a side channel compressor, the radially arranged in the circumferential direction Has cooling fins.

Ein weiteres Seitenkanalverdichtergehäuse ist durch die DE-U-92 15 231 bekannt. Bei diesem Gehäuse bestehen die Gehäusehälften aus Metall, z.B. Aluminium, und weisen daher eine ausreichende Festigkeit auf.Another side channel compressor housing is through DE-U-92 15 231 known. In this case, the case halves are made made of metal, e.g. Aluminum, and therefore have a sufficient strength.

Der Erfindung liegt die Aufgabe zugrunde, das Gehäuse eines Seitenkanalverdichters so zu gestalten, daß es bei einer Herstellung aus einem eine geringere Festigkeit als Metall aufweisenden Material, z.B. Kunststoff, den im Betrieb auftretenden Belastungen Stand zu halten vermag.The invention has for its object the housing one Side channel compressor to be designed so that it is in a manufacture from a lower strength than metal Material, e.g. Plastic, the one that occurs during operation Can withstand loads.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß der Radius der Ringe etwa dem Außen- und dem Innenradius des in den Gehäusehälften ausgebildeten Seitenkanals entspricht und zwischen diesen Ringen speichenartig erstreckende Rippenwände angeformt sind. Ein solches Gehäuse weist auch bei einer Herstellung aus Kunststoff eine ausreichende Festigkeit auf.The problem is solved according to the invention in that the radius of the rings approximately the outer and inner radius of the side channel formed in the housing halves corresponds and spokes-like extending between these rings Rib walls are formed. Such a housing also has a sufficient level when manufactured from plastic Firmness on.

Dadurch, daß der Radius der Ringe etwa dem Außen- und dem Innenradius des in den Gehäusehälften ausgebildeten Seitenkanales entspricht, kommen die Rippenwände an der Außenseite des den Seitenkanal bildenden Wandteiles zu liegen. Gerade diese Wandteile werden durch den Verdichtungsdruck beansprucht und somit durch die Rippenwände entsprechend gestützt.The fact that the radius of the rings about the outer and inner radius of the side channel formed in the housing halves corresponds, the rib walls come on the outside of the wall part forming the side channel. Just these wall parts are stressed by the compression pressure and thus supported accordingly by the rib walls.

Vorteilhafterweise kann einer der Ringe als Zentrierring ausgebildet werden. One of the rings can advantageously be designed as a centering ring become.

Eine weitere Erhöhung der Festigkeit des Gehäuses läßt sich dadurch erzielen, daß an der Frontwand zusätzlich zu den beiden Ringen ein radial weiter innen liegender, axial erstreckter Zentrierring angeformt ist und daß zwischen dem Zentrierring und dem zu diesem benachbarten Ring ebenfalls sich speichenartig erstreckende weitere Rippenwände an der Frontwand vorgesehen sind.A further increase in the strength of the housing can be achieve that in addition to the front wall both rings a radially inner, axially extended Centering ring is formed and that between the Centering ring and the ring adjacent to this also extending rib-like further rib walls on the Front wall are provided.

Dadurch, daß die weiteren Rippenwände gegenüber den Rippenwänden auf Lücke angeordnet sind, trägt der zwischen den weiteren Rückenwänden und den Rippenwänden liegende Ring zur Erhöhung der Festigkeit des Gehäuses bei, da zumindest ein Teil der Belastungskräfte über diesen Ring geleitet wird.The fact that the other rib walls opposite the rib walls are arranged on a gap, he carries between the others Back walls and the rib walls ring to increase the strength of the case, since at least part the load forces are passed through this ring.

Ferner können auch noch zwischen den Zentrierring und einem gegenüber diesem radial weiter innen liegenden Nabenansatz zusätzlich radial erstreckte Verstärkungsrippen an der Frontwand angeformt sein. Damit ist praktisch die gesamte Frontwand jeder Gehäusehälfte in entsprechender Weise verstärkt.Furthermore, between the centering ring and a compared to this radially inner hub approach additionally radially extending reinforcement ribs on the front wall be molded on. This is practically the entire front wall each housing half is reinforced accordingly.

Die Herstellung der Gehäusehälften aus Kunststoff bietet weiterhin die Möglichkeit, an den in der Trennebene der Gehäusehälften liegenden stirnseitigen Umfangskante an jeder Gehäusehälfte eine sich über die eine Umfangshälfte erstreckende Dichtlippe und eine sich über die andere Umfangshälfte erstreckende Dichtnut vorzusehen. Durch diese Dichtlippen und Dichtnuten, die beim Zusammenfügen der Gehäusehälften ineinandergreifen, wird eine hinreichende Abdichtung der zwischen den beiden Gehäusehälften bestehenden Trennfuge erreicht.The manufacture of the plastic housing halves continues to offer the possibility of in the parting plane of the housing halves lying front peripheral edge on each housing half one extending over the one half of the circumference Sealing lip and one extending over the other circumferential half Provide sealing groove. Through these sealing lips and Sealing grooves that interlock when the housing halves are joined together, a sufficient seal between the the existing joint between the two halves of the housing.

Erstrecken sich die Dichtlippe und die Dichtnut jeweils auf der einen und anderen Seite zu einer symmetrischén Teilungslinie der Gehäusehälften, dann ist eine identische Ausbildung beider Gehäusehälften möglich. Extend the sealing lip and the sealing groove each one side and the other to a symmetrical dividing line the housing halves, then is an identical training of both housing halves possible.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung nachfolgend näher beschrieben. Es zeigen:

die beiden Gehäusehälften eines Seitenkanalverdichtergehäuses im Schnitt entlang der Linie II-II in Fig. 1.
The invention is described in more detail below on the basis of an exemplary embodiment shown in the drawing. Show it:
Fig. 1
a plan view of a housing half of a side channel compressor housing, and
Fig. 2
the two housing halves of a side channel compressor housing in section along the line II-II in Fig. 1st

Mit 1 und 2 sind die beiden Gehäusehälften eines Seitenkanalverdichtergehäuses bezeichnet. An der Frontwand 3 jeder Gehäusehälfte sind ein erster und zweiter Ring 4 und 5 angeformt. Die Ringe 4 und 5 stehen gegenüber der Frontwand 3 axial vor und sind radial voneinander beabstandet. Der Radius des ersten Ringes 4 entspricht etwa dem Außenradius des in jeder Gehäusehälfte 1 und 2 ausgeformten Seitenkanales 6 und der Radius des zweiten Ringes etwa dem Innenradius des Seitenkanales 6.With 1 and 2 are the two housing halves of a side channel compressor housing designated. On the front wall 3 everyone Half of the housing are formed on a first and second ring 4 and 5. The rings 4 and 5 are opposite the front wall 3 axially in front and are radially spaced apart. The radius of the first ring 4 corresponds approximately to the outer radius of the in each housing half 1 and 2 shaped side channels 6 and the radius of the second ring approximately the inner radius of the Side channels 6.

Zwischen dem ersten und zweiten Ring 4 und 5 sind sich zwischen diesen beiden Ringen 4 und 5 speichenartig erstreckende Rippenwände 7 an der Außenseite des den Seitenkanal 6 bildenden Wandteiles 8 angeformt. Durch diese Rippenwände 7 wird insbesondere die Festigkeit dieses Wandteiles 8, welches durch den Verdichtungsdruck besonders stark beansprucht wird, wesentlich erhöht.Between the first and second ring 4 and 5 are between these two rings 4 and 5 spokes extending Rib walls 7 on the outside of the side channel 6 forming wall part 8 formed. Through these rib walls 7 in particular the strength of this wall part 8, which is particularly stressed by the compression pressure is significantly increased.

Konzentrisch zu den beiden Ringen 4 und 5 ist radial weiter innen liegend noch ein Zentrierring 9 an der Frontwand 3 jeder Gehäusehälfte 1 und 2 vorgesehen. In dem Bereich zwischen diesem Zentrierring 9 und dem benachbarten zweiten Ring 5 sind weitere Rippenwände 10 ausgebildet, die gegenüber den sich zwischen dem ersten und zweiten Ring 4 und 5 erstreckenden Rippenwänden 7 auf Lücke angeordnet sind. Hierdurch werden die Belastungskräfte auch in den zweiten Ring 5 eingeleitet, der somit zur Festigkeitserhöhung beiträgt.Concentric to the two rings 4 and 5 is radial further a centering ring 9 on the inside of the front wall 3 each housing half 1 and 2 provided. In that area between this centering ring 9 and the adjacent second Ring 5 further rib walls 10 are formed, the opposite extending between the first and second rings 4 and 5 Rib walls 7 are arranged on gap. Hereby the load forces are also in the second ring 5 initiated, which thus contributes to the increase in strength.

Zwischen dem Zentrierring 9 und einem radial noch weiter innen liegenden Nabenansatz 11 der Gehäusehälften 1 und 2 sind nochmals radial erstreckte Versträrkungsrippen 12 an der Frontwand 3 angeformt. Die Anzahl dieser Verstärkungsrippen 12 ist gegenüber der Anzahl der Rippenwände 7 und der weiteren Rippenwände 10 wegen des erheblich kleineren Kreisumfanges des Nabenansatzes 11 gegenüber dem Kreisumfang des Zentrierringes 9 auf ein Drittel reduziert. Die Verstärkungsrippen 12 sind gegenüber den weiteren Rippenwänden 10 wiederum auf Lücke angeordnet.Between the centering ring 9 and a radial even further internal hub shoulder 11 of the housing halves 1 and 2 are again radially extending reinforcement ribs 12 on the Molded on front wall 3. The number of these reinforcing ribs 12 is compared to the number of rib walls 7 and the other Rib walls 10 because of the significantly smaller circumference of the hub approach 11 with respect to the circumference of the Centering ring 9 reduced to a third. The reinforcement ribs 12 are in turn opposite the other rib walls 10 arranged on gap.

Wie aus der Draufsicht der Fig. 1 zu ersehen ist, sind am Umfang der Gehäusehälften 1 und 2 Augen 13 einteilig angeformt, die mit Durchstecköffnungen 14 für Verbindungsschrauben versehen sind. Mittels solcher Schrauben können die beiden Gehäusehälften 1 und 2 zu einem Seitenkanalverdichtergehäuse verbunden werden.As can be seen from the top view of FIG. 1, on Circumference of the housing halves 1 and 2 eyes 13 formed in one piece, those with through openings 14 for connecting screws are provided. By means of such screws, the two housing halves 1 and 2 to form a side channel compressor housing get connected.

Außerdem sind gleichmäßig über den Umfang der Gehäusehälften 1 und 2 verteilt drei rohrförmig ausgebildete Fußteile 15 vorgesehen. Im Hohlraum 16 der Fußteile 15 ist eine nach radial innen vorspringende Anschlagschulter 17 ausgebildet, auf der Befestigungsschrauben mit ihrem Schraubenkopf aufruhen können, die bei einer Aufstellung des Seitenkanalverdichters mit senkrechter Achse in die Fußteile 15 eingeführt werden.They are also even over the circumference of the housing halves 1 and 2 distributes three tubular foot parts 15 intended. In the cavity 16 of the foot parts 15 is one after radially inwardly projecting stop shoulder 17, rest on the fastening screws with their screw heads can, when installing the side channel blower inserted into the foot parts 15 with a vertical axis become.

An den Gehäusehälften 1 und 2 sind weiterhin Vorprägungen 18 für eine Einlaß- und eine Auslaßöffnung vorgesehen. Diese Vorprägungen 18 werden dann bei der entsprechenden Gehäusehälfte entfernt. Desgleichen sind Vorprägungen 19 für eine Welleneinführöffnung und Vorprägungen 20 für Befestigungslöcher an den Gehäusehälften vorhanden. Diese Vorprägungen 19 und 20 werden dann ebenfalls bei der entsprechenden Gehäusehälfte entfernt.Knockouts 18 are also provided on the housing halves 1 and 2 provided for an inlet and an outlet opening. This Knockouts 18 are then in the corresponding housing half away. Likewise, knockouts 19 for one Shaft insertion opening and knockouts 20 for fastening holes present on the housing halves. These knockouts 19 and 20 are then also in the corresponding housing half away.

Die Gehäusehälften 1 und 2 können damit in gleicher Form, d.h. identisch ausgeführt werden. Hierzu müssen lediglich die Fußteile 15 und die Vorprägungen 18 bis 20 symmetrisch zu einer Halbierungslinie, welche in der Mitte zwischen den Vorprägungen 18 für die Ein- und Auslaßöffnung verläuft, angeordnet werden.The housing halves 1 and 2 can thus in the same shape, i.e. be carried out identically. To do this, only the Foot parts 15 and the knockouts 18 to 20 symmetrically a halving line, which is in the middle between the knockouts 18 runs for the inlet and outlet opening, arranged become.

An der in der Trennebene 21 der Gehäusehälften 1 und 2 liegenden stirnseitigen Umfangskante 22 ist jeweils eine sich auf der einen Seite der Halbierungslinie über die eine Umfangshälfte erstreckende Dichtlippe 23 und eine sich auf der anderen Seite der Halbierungslinie über die andere Umfangshälfte erstreckende Dichtnut 24 vorgesehen. Beim Zusammenfügen der Gehäusehälften 1 und 2 greifen die Dichtlippen 23 und die Dichtnuten 24 ineinander und sorgen für eine gute Abdichtung der zwischen den beiden miteinander verbundenen Gehäusehälften 1 und 2 bestehenden Trennfuge.On the parting plane 21 of the housing halves 1 and 2 lying front peripheral edge 22 is one each on one side of the halving line over one Circumferential half extending sealing lip 23 and one the other side of the bisector over the other Circumferential half extending sealing groove 24 is provided. At the Joining the housing halves 1 and 2 engage the sealing lips 23 and the sealing grooves 24 into each other and ensure a good seal of those connected between the two Housing halves 1 and 2 existing parting line.
