The construction of such a compressor set and the distribution of the connecting forces are improved in that at least the two casing sections (8, 9) in the middle of the compressor set are cast in the same way and the design of the connecting plates (10, 10a) on them is such that there is still space for fitting a further connector (13) on either side of a connector (13) which can be arranged at the peripheral centre of the connecting plates (10, 10a).

Description

VerdichteraggregatCompressor unit
Die Erfindung betrifft ein Verdichteraggregat gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a compressor unit according to the preamble of claim 1.
Ein solches Verdichteraggregat ist durch das DE-U-77 15 000 bekannt. Bei diesem Aggregat sind die für die beiden Seitenkanalverdichter erforderlichen vier Gehäusehälften alle unterschiedlich ausgebildet. Dies führt zu einem hohen Fertigungaufwand. Die Verbindung der einzelnen Gehäuseteile erfolgt durch ein Zwischenfügen der mittleren Gehäuseteile zwischen die äußeren Gehäuseteile, die mittels Zugankern, welche an an den äußeren Gehäuseteilen vorgesehenen Verbin¬ dungslaschen angreifen, miteinander verbunden sind. Somit muß die gesamte Kraft von den Verbindungslaschen der äußeren Gehäuseteile aufgenommen werden.Such a compressor unit is known from DE-U-77 15 000. In this unit, the four housing halves required for the two side channel blowers are all designed differently. This leads to high manufacturing costs. The connection of the individual housing parts takes place by interposing the middle housing parts between the outer housing parts, which are connected to one another by means of tie rods which engage on connecting straps provided on the outer housing parts. The entire force must therefore be absorbed by the connecting straps of the outer housing parts.
Der Erfindung liegt die Aufgabe zugrunde, ein Verdichter¬ aggregat zu schaffen, das einfacher zu fertigen ist und bei dem die für die Verbindung der Gehäusehälften notwendigen Kräfte besser verteilt sind.The object of the invention is to create a compressor unit which is easier to manufacture and in which the forces required for connecting the housing halves are better distributed.
Die Lösung der gestellten Aufgabe gelingt durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale. Durch die gußtechnisch gleiche Ausbildung zumindest der innen¬ liegenden Gehäusehälften wird der Aufwand für die zur Herstellung der Gehäusehälften notwendigen Druckgußwerk¬ zeuge reduziert. Hierbei wird durch die besondere Gestaltung der Verbindungslaschen eine gute Durchleitung der Kräfte in axialer Richtung erreicht, ohne daß schädliche Biegemomente in Kauf genommen werden müssen. Außerdem können die beiden inneren Gehäusehälften vorab zu einer Baugruppe zusammengefügt werden. Eine von Biegemomenten vollkommen freie Verbindung der Gehäusehälften läßt sich dadurch erreichen, daß jeweils zwei auf der einen Stirnseite der jeweiligen Gehäusehälfte liegenden Verbindungslaschen eine zu diesen Verbindungs- laschen symmetrisch ausgerichtete, auf der anderen Stirn¬ seite der Gehäusehälfte liegende Verbindungslasche zugeord¬ net ist.The problem is solved by the features specified in the characterizing part of claim 1. Due to the same design in terms of casting technology, at least the inner housing halves, the outlay for the die casting tools required for producing the housing halves is reduced. Due to the special design of the connecting lugs, good transmission of the forces in the axial direction is achieved without having to accept harmful bending moments. In addition, the two inner housing halves can be assembled into an assembly in advance. A connection of the housing halves that is completely free of bending moments can be achieved by assigning two connecting lugs on one end face of the respective housing half to a connecting lug symmetrically aligned with these connecting lugs and lying on the other end face of the housing half.
Die Durchleitung der Kräfte über die volle axiale Länge des Aggregates ohne schädliche Biegemomente gelingt nach einer Ausgestaltung der Erfindung dadurch, daß auch an den außen¬ liegenden Gehäusehälften den Verbindungslaschen der in der Mitte liegenden Gehäusehälften entsprechende Verbindungs¬ laschen vorgesehen sind.The transmission of the forces over the full axial length of the unit without damaging bending moments is achieved according to one embodiment of the invention in that the connecting tabs of the center housing halves are also provided with connecting tabs on the outer housing halves.
Besonders zweckmäßig ist es, daß die beiden Verbindungs¬ laschen mit ihren einander zugewandten Seiten in etwa fluchtend zu den Außenseiten der einen Verbindungslasche ausgerichtet sind. Bei einem derartigen Verdichteraggregat läßt sich eine Entlastung des eigentlichen Gehäuses von den Verbindungskräften dadurch erreichen, daß die zu den beiden Stirnseiten der Gehäusehälften angeordneten Verbindungs¬ laschen durch sich axial erstreckende Stege miteinander verbunden sind, wobei die Stege an den beiden Verbindungs- laschen im Bereich von deren einander zugewandten Seiten und an der einen Verbindungslasche im Bereich von deren Außenseiten angreifen.It is particularly expedient for the two connecting lugs with their mutually facing sides to be aligned approximately in alignment with the outer sides of the one connecting lug. With such a compressor unit, the actual housing can be relieved of the connecting forces by connecting the connecting lugs arranged on the two end faces of the housing halves to one another by means of axially extending webs, the webs on the two connecting lugs in the region of their mutually facing sides and on the one connecting lug engage in the area of their outer sides.
Anhand eines in der Zeichnung dargestellten Ausführungsbei- spieles wird die Erfindung nachfolgend näher beschrieben. Es zeigt:The invention is described in more detail below on the basis of an exemplary embodiment shown in the drawing. It shows:
FIG 1 ein aus zwei Seitenkanalverdichtern bestehendes Verdichteraggregat im Schnitt, FIG 2-4 jeweils eine Verbindungsvariante der einzelnen Gehäusehälften in Draufsicht. Mit 1 ist die äußere Gehäusehälfte des einen Seitenkanal¬ verdichters 2 des Verdichteraggregates bezeichnet, die auf der der Antriebsseite des Verdichteraggregates abgewandten Seite liegt und mit einer Lagerbohrung 3 für ein endseitiges Lager 4 der Antriebswelle 5 des Aggregates versehen ist. Zwischen der äußeren Gehäusehälfte 6 des anderen Seitenkanalverdichters 7 sind die inneren Gehäuse¬ hälften 8 und 9 der beiden Seitenkanalverdichter 2 und 7 angeordnet.1 shows a compressor unit consisting of two side channel compressors in section, FIGS. 2-4 each show a connection variant of the individual housing halves in plan view. 1 designates the outer housing half of a side channel compressor 2 of the compressor unit, which lies on the side facing away from the drive side of the compressor unit and is provided with a bearing bore 3 for an end bearing 4 of the drive shaft 5 of the unit. The inner housing halves 8 and 9 of the two side channel compressors 2 and 7 are arranged between the outer housing half 6 of the other side channel compressor 7.
Die äußere Gehäusehälfte 6 des anderen Seitenkanalverdich¬ ters 7 und die beiden inneren Gehäusehälften 8 und 9 sind gußtechnisch gleich ausgebildet. Diese Gehäusehälften 6,8 und 9 müssen daher nur hinsichtlich notwendiger Bohrungen und Zentrierränder entsprechend bearbeitet werden. Für die Verbindung der einzelnen Gehäusehälften 1,6,8 und 9 mitein¬ ander sind an deren Außenumfang Verbindungslaschen 10 bzw.10a vorgesehen. Diese weisen entsprechende Durch- Steckbohrungen 11 und Gewindelöcher 12 auf, in die Schrauben 13 als Verbindungselemente einbringbar sind.The outer housing half 6 of the other side channel compressor 7 and the two inner housing halves 8 and 9 have the same casting technology. These housing halves 6, 8 and 9 must therefore only be machined accordingly with regard to the necessary bores and centering edges. For the connection of the individual housing halves 1, 6, 8 and 9 to one another, connecting straps 10 and 10a are provided on their outer circumference. These have corresponding through bores 11 and threaded holes 12, into which screws 13 can be introduced as connecting elements.
Die gußtechnisch gleiche Ausbildung der inneren Gehäuse¬ hälften 8 und 9 sowie der äußeren Gehäusehälfte 6 des anderen Seitenkanalverdichters 7 erfordert eine entspre¬ chende Gestaltung der Verbindungslaschen 10, damit diese auch nach Umschlag der entsprechenden Gehäusehälften zusammenpassen.The same technical design of the inner housing halves 8 and 9 and the outer housing half 6 of the other side channel compressor 7 requires a corresponding design of the connecting straps 10 so that they fit together even after the corresponding housing halves have been turned over.
Wie aus den FIG 2 und 3 zu ersehen ist, sind auf der einen Stirnseite 14 jeder Gehäusehäfte 1,6,8 und 9 jeweils zwei Verbindungslaschen 10 mit umfangsmäßigem Abstand zueinander angeordnet. Auf der anderen Stirnseite 15 der Gehäuse¬ hälften 1,6,8 und 9 ist jeweils eine mittig zu den beiden Verbindungslaschen 10 der einen Stirnseite 14 angeordnete Verbindungslasche 10a vorgesehen. Durch das wegen der gleichen Ausbildung der Gehäusehälften 6,8 und 9 teilweise notwendige Wenden der entsprechenden Gehäusehälften kommen entweder die beiden Verbindungslaschen 10 oder die einzelne Verbindungslasche 10a voreinander zu liegen und können somit mittels entsprechender Schrauben 13 verbunden werden. Wegen des umfangsmäßigen Versatzes der Verbindungslaschen 10 gegenüber der einzelnen Verbindungslasche 10a ist seit- lieh zu dieser einzelnen Verbindungslasche 10a die Anbrin¬ gung weiterer Verbindungselemente möglich.As can be seen from FIGS. 2 and 3, two connecting straps 10 are arranged on the one end face 14 of each housing section 1, 6, 8 and 9 with a circumferential distance from one another. On the other end 15 of the housing halves 1, 6, 8 and 9 there is a connection lug 10a arranged centrally to the two connecting lugs 10 of the one end 14. Because of that same design of the housing halves 6, 8 and 9 partially necessary turning of the corresponding housing halves, either the two connecting lugs 10 or the individual connecting lug 10 a come to lie in front of one another and can therefore be connected by means of corresponding screws 13. Because of the circumferential offset of the connecting tabs 10 with respect to the individual connecting tab 10a, further connecting elements can be attached to this individual connecting tab 10a.
Bei der Ausführungsvariante nach FIG 2 sind die voreinan- derliegenden einzelnen Verbindungslaschen 10a jeweils mittels einer einzelnen Schraube 13 miteinander verbunden. Bei den beiden voneinander beabstandeten Verbindungslaschen 10 kann eine Verschraubung an einer oder beiden Verbin¬ dungslaschen 10 erfolgen. Eine Verschraubung an beiden Verbindungslaschen 10 führt zu einer vollkommenen Symmetrie hinsichtlich der auftretenden Verbindungskräfte insgesamt. Bei der AusführungsVarianten nach FIG 3 erfolgt die Verbin¬ dung der einzelnen Verbindungslaschen 10a mittels einer sich durchgehend über die inneren Gehäusehälften 8 und 9 erstreckenden Schraube 13.In the embodiment variant according to FIG. 2, the individual connecting lugs 10a lying in front of one another are each connected to one another by means of a single screw 13. In the case of the two spaced-apart connecting straps 10, one or two connecting straps 10 can be screwed together. A screw connection on both connecting straps 10 leads to a complete symmetry with regard to the connecting forces that occur overall. 3, the individual connecting lugs 10a are connected by means of a screw 13 which extends continuously over the inner housing halves 8 and 9.
Zur Erhöhung der Festigkeit sind die beiden auf der einen Stirnseite 14 liegenden Verbindungslaschen 10 über sich axial erstreckende Stege 16 jeweils mit der auf der anderen Stirnseite 15 liegenden einzelnen Verbindungslasche 10a verbunden. Die Stege 16 erstrecken sich von den einander zugewandten Seiten der beiden Verbindungslaschen 10 zu den Außenseiten der einzelnen Verbindungslaschen 10a. Damit verbleibt umfangsmäßig zwischen den Stegen 16 ein Raum, durch den die Schrauben 13 hindurchgeführt werden können. Die Darstellung nach FIG 4 zeigt eine weitere Verbindungs¬ variante. Gegenüber den in den FIG 2 und 3 dargestelltenIn order to increase the strength, the two connecting straps 10 on one end face 14 are each connected via axially extending webs 16 to the individual connecting strap 10a lying on the other end face 15. The webs 16 extend from the mutually facing sides of the two connecting straps 10 to the outer sides of the individual connecting straps 10a. This leaves a space circumferentially between the webs 16 through which the screws 13 can be passed. The illustration according to FIG. 4 shows a further connection variant. Compared to that shown in FIGS. 2 and 3
Varianten sind die beiden umfangsmäßig voneinander beab- standeten Verbindungslaschen 10 zu einer durchgehenden, verbreiterten Verbindungslasche 17 auf der einen Stirnseite 14 zusammengefaßt. Von diesen verbreiterten Verbindungs¬ laschen 17 erstrecken sich jeweils zwei umfangsmäßig voneinander beabstandete Stützstege 18 in axialer Richtung zu anderen Stirnseite 15 der Gehäusehälften 1,6,8 bzw.9. Die inneren Gehäusehälften 8 und 9 sind durch in den verbreiterten Verbindungslaschen 17 eingebrachte Schrauben miteinander verbunden. Die Verbindung der äußeren Gehäuse- hälften 1 und 6 miteinander und mit den inneren Gehäuse¬ hälften 8 und 9 erfolgt mittels in der Mitte der verbrei¬ terten Verbindungslaschen 17 angeordneter, durchgehender Zuganker 19, die an den verbreiterten Verbindungslaschen 17 der äußeren Gehäusehälften 1 und 6 angreifen. Variants are the two circumferentially spaced connecting tabs 10 combined to form a continuous, widened connecting tab 17 on one end face 14. From these widened connecting straps 17, two circumferentially spaced support webs 18 each extend in the axial direction to other end faces 15 of the housing halves 1, 6, 8 or 9. The inner housing halves 8 and 9 are connected to one another by screws introduced into the widened connecting straps 17. The connection of the outer housing halves 1 and 6 to one another and to the inner housing halves 8 and 9 takes place by means of continuous tie rods 19 arranged in the middle of the widened connecting plates 17, which on the widened connecting plates 17 of the outer housing halves 1 and 6 attack.
