Abstract

PCT No. PCT/DE92/00167 Sec. 371 Date Sep. 20, 1993 Sec. 102(e) Date Sep. 20, 1993 PCT Filed Mar. 2, 1992 PCT Pub. No. WO92/16752 PCT Pub. Date Oct. 1, 1992.A regenerative compressor has a housing in which an impeller (6) rotates. The impeller has a supporting ring (7) fitted with blades (8) and is connected by a wall section (9) to a hub element (10) which can be placed on a drive shaft (5). The wall section (9) forms one lateral boundary wall of the impeller (6) and its axial thickness is less than the axial width of the impeller (6). The other boundary wall of the impeller is formed by an annular cover part (14) secured to the impeller. The cover part extends along at least a partial region between the supporting ring (7) and the hub element (10) and its rim is applied to a corner recess (17) of the supporting ring (7). The compressor also has rectilinear sealing gaps (13 and 23) which extend linearly along their whole length between the boundary walls of the impeller (6) and the walls (12 and 22) of the housing. To simplify the assembly of the cover part, the cover part (14) extends over the whole region between supporting ring (7) and hub element (10) and is clamped axially against the supporting ring (7) and against the hub element (10).

Description

SeitenkanalVerdichterSide channel compressor
Die Erfindung betrifft einen Seitenkanalverdichter gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a side channel compressor according to the preamble of claim 1.
Ein solcher Seitenkanalverdichter ist durch das DE-U-74 18 776 bekannt. Bei diesem Verdichter ist das Abdeckteil durch Vernieten an dem Laufrad befestigt. Außerdem erstreckt es sich nur über einen Teilbereich zwischen dem Tragring und dem Naben¬ teil. Damit kann sich in dem nicht überdeckten Bereich des Laufrades leicht Schmutz ablagern.Such a side channel compressor is known from DE-U-74 18 776. In this compressor, the cover part is attached to the impeller by riveting. In addition, it extends only over a partial area between the support ring and the hub part. This can easily deposit dirt in the uncovered area of the impeller.
Der Erfindung liegt die Aufgabe zugrunde, einen Seitenkanalver- dichter der gattungsgemäßen Art so weiterzubilden, daß das Abdeckteil wesentlich einfacher am Laufrad zu montieren ist.The invention has for its object to develop a side channel compressor of the generic type so that the cover is much easier to mount on the impeller.
Die Lösung der gestellten Aufgabe gelingt durch die im Kenn¬ zeichen des Anspruchs 1 angegebenen Merkmale. Es wird hier- durch nicht nur eine einfachere Montage des Abdeckteils erreicht, sondern auch gleichzeitig wegen der vollständigen Uberdeckung des zwischen dem Tragring und dem Nabenteil liegenden Bereiches durch das Abdeckteil eine Schmutzablagerung in den ansonsten offenen Hohlräumen und Nischen des Laufrades verhindert. Dies ist besonders dann von Vorteil, wenn der Seitenkanalverdichter in Bereichen eingesetzt wird, wo die geförderte Luft mit faserartigen Partikeln belastet ist, wie dies beispielsweise in der Textilindustrie häufig vorkommt.The problem is solved by the features specified in the characterizing part of claim 1. In this way, not only is the cover part easier to assemble, but at the same time dirt is prevented in the otherwise open cavities and niches of the impeller because of the complete covering of the area between the support ring and the hub part by the cover part. This is particularly advantageous when the side channel blower is used in areas where the conveyed air is contaminated with fibrous particles, as is often the case in the textile industry.
Die kennzeichnenden Merkmale der Ansprüche 2 und 3 beschreiben zwei Ausführungsvarianten des Seitenkanalverdichters, nach denen sich auf einfache Weise ein Verspannen des Abdeckteiles erreichen läßt. Bei der Ausgestaltung des Seitenkanalverdichters nach den kenn¬ zeichnenden Merkmalen des Anspruchs 4 kann die ohnehin für das Befestigen des Nabenteils auf der Antriebswelle notwendige Schraube auch das Andrücken des Spannringes übernehmen. Somit ist kein zusätzliches Bauteil zum Aufbringen der Spannkraft erforderlich.The characterizing features of claims 2 and 3 describe two design variants of the side channel compressor, according to which a tensioning of the cover part can be achieved in a simple manner. In the configuration of the side channel compressor according to the characterizing features of claim 4, the screw, which is necessary anyway for fastening the hub part to the drive shaft, can also take over the pressing of the clamping ring. This means that no additional component is required to apply the clamping force.
Anhand eines in der Zeichnung dargestellten Ausführungsbei¬ spieles wird der Anmeldungsgegenstand nachfolgend näher beschrieben. Es zeigt:The subject of the application is described in more detail below with reference to an exemplary embodiment shown in the drawing. It shows:
FIG 1 einen mit einem Antriebsmotor verbundenen Seitenkanal¬ verdichter im Schnitt, FIG 2 ein kegelförmig ausgebildetes Abdeckteil im Schnitt.1 shows a side channel compressor connected to a drive motor in section, FIG. 2 shows a conical cover part in section.
Mit 1 ist ein mit einem Antriebsmotor 2 verbundener Seiten¬ kanalverdichter bezeichnet, dessen Gehäuse aus einer ersten und einer zweiten Gehäusehälfte 3 und 4 besteht. Der Seitenkanal¬ verdichter 1 besitzt ferner ein Laufrad 6. Das Laufrad 6 weist einen Tragring 7 auf, an dem die Förderschaufeln 8 des Lauf¬ rades 6 angeordnet sind. Über ein Wandteil 9 ist der Tragring 7 mit einem auf dem herausgeführten Ende der Welle 5 des Antriebsmotors 2 aufgesteckten Nabenteil 10 verbunden. Das Nabenteil 10 ist mit der Welle 5 drehfest gekoppelt.1 denotes a side-channel compressor connected to a drive motor 2, the housing of which consists of a first and a second housing half 3 and 4. The side channel compressor 1 also has an impeller 6. The impeller 6 has a support ring 7 on which the conveyor blades 8 of the impeller 6 are arranged. Via a wall part 9, the support ring 7 is connected to a hub part 10 which is plugged onto the end of the shaft 5 of the drive motor 2. The hub part 10 is rotatably coupled to the shaft 5.
Die Wandstärke des Wandteils 9 ist dünner als die axiale Breite des Laufrades 6 bemessen. Außerdem ist das Wandteil 10 zu der einen Seite des Laufrades 6 hin angeordnet, so daß es die eine Begrenzungswand des Laufrades 6 bildet. Durch diese seitliche Anordnung des Wandteiles 9 ergibt sich eine nischenformige Aus¬ nehmung 11 des Laufrades 6.The wall thickness of the wall part 9 is thinner than the axial width of the impeller 6. In addition, the wall part 10 is arranged on one side of the impeller 6 so that it forms the one boundary wall of the impeller 6. This lateral arrangement of the wall part 9 results in a niche-shaped recess 11 in the impeller 6.
Um eine gute Förderleistung des Seitenkanalverdichters zu erreichen, ist es wichtig, daß die Druckverluste, die über die zwischen rotierenden und feststehenden Teile bestehenden Spalte entstehen, möglichst gering gehalten werden. Dies kann sowohl durch möglichst enge als auch möglichst lange Spalte erreicht werden.In order to achieve a good delivery performance of the side channel blower, it is important that the pressure drops over the gaps existing between rotating and fixed parts arise, be kept as low as possible. This can be achieved by gaps that are as narrow as possible and as long as possible.
Zwischen der durch das Wandteil 9 gebildeten einen Begrenzungs¬ wand des Laufrades 6 und der dazu parallel verlaufenden Wand 12 der ersten Gehäusehälfte 3 ist daher ein relativ langer, schmaler Spalt 13 gebildet.A relatively long, narrow gap 13 is therefore formed between the one boundary wall of the impeller 6 formed by the wall part 9 and the wall 12 of the first housing half 3 running parallel thereto.
Auf der dem Wandteil 9 gegenüberliegenden Seite ist ein sich vom Tragring 7 bis zum Nabenteil 10 erstreckendes Abdeckteil 14 aus Blech oder Kunststoff vorgesehen. Das Abdeckteil 14 ist als runde Scheibe ausgebildet und weist eine Wellenöffnung 15 auf, so daß es auf das Ende der Welle 5 aufsteckbar ist. Mit seinem Umfangsrand 16 liegt das Abdeckteil 14 in einer am Tragring 7 ausgebildeten Eckausnehmung 17 an. Mittels einer in das Ende der Welle 5 eingeschraubten Schraube 18, die über eine Zwischen¬ scheibe 19 auf einen auf das Wellenende lose aufgesteckten Spannring 20 einwirkt, wird das auf das Wellenende aufgesteckte Abdeckteil 14 im Bereich seiner Wellenöffnung 15 gegen eine Anschlagfläche 21 des Nabenteils 10 gepreßt.On the side opposite the wall part 9, a cover part 14 made of sheet metal or plastic extends from the support ring 7 to the hub part 10. The cover part 14 is designed as a round disk and has a shaft opening 15 so that it can be plugged onto the end of the shaft 5. With its peripheral edge 16, the cover part 14 rests in a corner recess 17 formed on the support ring 7. By means of a screw 18 screwed into the end of the shaft 5, which acts via an intermediate washer 19 on a clamping ring 20 loosely fitted onto the shaft end, the cover part 14, which is plugged onto the shaft end, is pressed in the region of its shaft opening 15 against a stop surface 21 of the hub part 10 pressed.
Die für die Halterung des Abdeckteils 14 an dem Laufrad 6 not¬ wendige axiale Verspannung desselben kann dadurch erreicht werden, daß das Abdeckteil 14, wie in FIG 2 gezeigt, kegel¬ förmig ausgebildet ist. Hierdurch ergibt sich beim Anziehen der Schraube 18 eine in axialer Richtung wirkende Kraft, welche das Abdeckteil 14 mit seinem Umfangsrand 16 in die Eckausneh¬ mung 17 des Tragringes 7 preßt.The axial bracing of the cover part 14 which is necessary for holding the cover part 14 on the impeller 6 can be achieved in that the cover part 14, as shown in FIG. 2, is conical. This results in a force acting in the axial direction when the screw 18 is tightened, which presses the cover part 14 with its peripheral edge 16 into the corner recess 17 of the support ring 7.
Das axiale Andrücken des Abdeckteils 14 in die Ausnehmung 17 kann bei vollkommen ebener Ausbildung des Abdeckteils 14 dadurch erreicht werden, daß die am Nabenteil 10 ausgebildete Anschlagfläche 21 in ihrer Ebene gegenüber der Ebene der axialen Anschlagfläche der Eckausnehmung 17 des Tragringes 7 zurückgesetzt ist, wie dies in FIG 1 an dem Nabenteil 10 gestrichelt angedeutet ist. Auch bei einer solchen Ausgestaltung wird beim Anziehen der Schraube 18 eine axiale Andrückkraft erzeugt, welche das Abdeckteil 14 in der Eckausnehmung 17 in Anlage an der entsprechenden Anschlagfläche der Eckausnehmung 17 hält.The axial pressing of the cover part 14 into the recess 17 can be achieved with a completely flat design of the cover part 14 in that the stop surface 21 formed on the hub part 10 in its plane relative to the plane of the axial stop surface of the corner recess 17 of the support ring 7 is reset, as is indicated by dashed lines in FIG. 1 on the hub part 10. Even with such a configuration, when the screw 18 is tightened, an axial pressing force is generated which holds the cover part 14 in the corner recess 17 in contact with the corresponding stop surface of the corner recess 17.
Das am Laufrad 6 befestigte Abdeckteil 14 bildet die andere Begrenzungswand des Laufrades 6. Zwischen dieser anderen Begrenzungswand und der zu dieser nahezu parallel verlaufenden entsprechenden Wand 22 der zweiten Gehäusehälfte 4 wird somit ebenfalls ein langer schmaler Spalt 23 gebildet. Die somit zu beiden Seiten des Laufrades bestehenden Spalte 13 und 23 zeichnen sich durch eine große Dichtwirkung aus.The cover part 14 fastened to the impeller 6 forms the other boundary wall of the impeller 6. A long, narrow gap 23 is thus also formed between this other boundary wall and the corresponding wall 22 of the second housing half 4 which runs almost parallel to this. The gaps 13 and 23 thus existing on both sides of the impeller are distinguished by a large sealing effect.
Da das Abdeckteil 14 die nischenformige Ausnehmung 11 des Lauf¬ rades 6 vollständig überdeckt, wird ferner die Ablagerung von Schmutz in dieser Ausnehmung verhindert. Since the cover part 14 completely covers the niche-shaped recess 11 of the impeller 6, the deposition of dirt in this recess is also prevented.
