Getriebeverdichter und Verfahren zur Montage Gear compressor and method of assembly
Die Erfindung betrifft einen Getriebeverdichter umfassend ein Getriebe und mindestens einen als Turboverdichter ausgebilde¬ ten Verdichter, wobei das Getriebe zum Antrieb des Verdich¬ ters eine Verdichterantriebswelle, die drehmomentübertragend mit einem um eine Rotationsachse X drehbar ausgebildetenThe invention relates to a gear transmission comprising a compressor and at least one as a turbo-compressor having formed ¬ th compressor, wherein said transmission for driving the compaction ¬ ters a compressor driving shaft formed with a torque-transmitting manner about a rotation axis X rotatably
Impeller des Verdichters verbunden ist, wobei der Verdichter ein Gehäuse aufweist, wobei das Gehäuse Anformungen aufweist zum Abstützen an Auflagen des Getriebeverdichters. Weiterhin beschäftigt sich die Erfindung mit einem Verfahren zur Monta- ge eines Getriebeverdichters, insbesondere eines Getriebever¬ dichters der eingangs definierten Art, wobei schrittweise zu¬ nächst ein Getriebe mit einem um eine Rotationsachse drehba¬ ren Impeller des Getriebeverdichters drehmomentübertragend montiert bereitgestellt werden und anschließend ein Impeller of the compressor is connected, wherein the compressor has a housing, wherein the housing has projections for supporting on supports of the gear compressor. Furthermore, the invention being gradually ¬ a transmission with a about a rotation axis drehba ¬ ren impellers of the geared compressor mounted for torque transmission are provided next, and then concerned with a method for mount- ing ge of a geared compressor, in particular a Getriebever ¬ dichters of the type defined, a
Verdichtergehäuse in axialer Richtung derart an das Getriebe herangeführt wird, dass in axialer Endposition dieser Bewe¬ gung der Impeller von dem Verdichtergehäuse umgeben ist. Compressor housing in the axial direction is brought to the gearbox so that in the axial end position of this movement ¬ movement of the impeller is surrounded by the compressor housing.
Getriebeverdichter der eingangs definierten Art sind bereits aus der deutschen Patentschrift DE 44 23 784 C2 bekannt. Die strömungsführenden Gehäuse von derartigen Getriebeverdichtern, die auch als Prozessgasradialturbinen bezeichnet werden, werden im Regelfall mit senkrechter Stutzenstellung ausgeführt. Das bedeutet, dass der Einlaufstutzen sich in verti- kaier Richtung nach oben erstreckt und das zu verdichtende Fluid von oben nach unten in das strömungsführende Gehäuse bzw. an den Impeller heranströmt. Größere Abmaße des Gear compressor of the type defined are already known from German Patent DE 44 23 784 C2. The flow-guiding housing of such transmission compressors, which are also referred to as process gas radial turbines, are usually carried out with vertical nozzle position. This means that the inlet nozzle extends upward in the vertical direction and the fluid to be compressed flows from top to bottom in the flow-guiding housing or on the impeller. Bigger dimensions of the
Verdichtergehäuses stellen bei der Montage eine Herausforde¬ rung dar, da eine gängige Montagemethode vorsieht, dass das Verdichtergehäuse über das Laufrad - also das Laufrad fort¬ schreitend umgebend - an das Getriebe seitlich bzw. in axia¬ ler Richtung der Impellerrotationsachse, herangeführt wird. Hierbei bleibt zwischen dem Verdichtergehäuse und dem an dem Getriebe bereits angebrachten Impeller in der Regel ein Radialspiel von lediglich wenigen Millimetern, z.B. 5mm, so dass eine entsprechen genaue Führung dieser axialen Montagebewegung unter Baustellenbedingungen eine aufwendige Herausforde- rung bedeutet. Compressor housing provide in the assembly constitutes a chal ¬ tion, since a common assembly method provides that the compressor housing via the impeller - that the impeller continues ¬ border surrounding - is brought up laterally to the transmission or in axia ¬ ler direction of Impellerrotationsachse. This remains between the compressor housing and on the Gearbox already mounted impeller usually a radial clearance of only a few millimeters, eg 5mm, so that a correspondingly accurate guide this axial assembly movement under construction site conditions means a complex challenge.
Die Erfindung hat es sich zur Aufgabe gemacht, den eingangs definierten Getriebeverdichter bzw. das eingangs definierte Montageverfahren derart weiterzubilden, dass die Montage des Verdichtergehäuses eines Getriebeverdichters auch unter Bau¬ stellenbedingungen sicherer erfolgen kann. The invention has set itself the task of developing the transmission compressor defined at the outset or the initially defined mounting method such that the assembly of the compressor housing of a gear compressor can be made safer even under construction ¬ site conditions.
Aus der JP1320397A1 ist bereits eine Anordnung aus einem Antrieb und einem Verdichter bekannt, bei der ein From JP1320397A1 an arrangement of a drive and a compressor is already known in which a
Verdichtergehäuse auf einer gemeinsamen Grundplatte mit demCompressor housing on a common base plate with the
Antrieb befestigt ist. Aus der DE DE4423784C2 ist ein Getrie¬ beverdichter bekannt, bei der ein Antrieb an dem Getriebege¬ häuse axial verschieblich angebracht ist. Zur Lösung der erfindungsgemäßen Aufgabe wird ein Getriebeverdichter der eingangs genannten Art vorgeschlagen, der mittels der Merkmale des kennzeichnenden Teils des Anspruchs 1 fortgebildet ist. Weiterhin wird ein Montageverfahren gemäß dem unabhängigen Verfahrensanspruch vorgeschlagen. Die je- weils rückbezogenen Unteransprüche beinhalten vorteilhafte Weiterbildungen der Erfindung. Drive is attached. From DE DE4423784C2 a Getrie ¬ Bever closer is known, in which a drive is attached to the housing axially displaceable Getriebege ¬. To achieve the object of the invention, a gear compressor of the type mentioned is proposed, which is further developed by means of the features of the characterizing part of claim 1. Furthermore, an assembly method according to the independent method claim is proposed. The respective dependent claims contain advantageous developments of the invention.
In der Begriffswelt der Erfindung bedeutet die Richtungsanga¬ be „axial" - wenn nicht anders angegeben - die axiale Rich- tung der Rotationsachse des eines Impellers des Verdichters der in dem Verdichtergehäuse angeordnet ist In the terminology of the invention the Richtungsanga ¬ be "axially" means - if not otherwise stated - the axial catch towards the axis of rotation of an impeller of the compressor is disposed in the compressor housing
Die erfindungsgemäße Ausbildung von Paaren von Anformungen an dem Verdichtergehäuse und Auflagern des Getriebeverdichters unter Zwischenanordnung von Lagerelementen, derart, dass die beschriebene axiale Bewegung im Rahmen der Montage derart ge¬ führt ist, dass ein Kollisionskontakt zwischen dem The inventive design of pairs of projections on the compressor housing and bearing of the gear compressor with interposition of bearing elements, such that the described axial movement in the context of the assembly is so ge ¬ leads that a collision contact between the
Verdichterlaufrad und dem Verdichtergehäuse nicht stattfinden kann, ermöglicht eine Montage auf der Baustelle mit dort ein¬ fach verfügbaren Mitteln, beispielsweise mittels eines weniger präzisen Autokrans. Diese Eigenschaften sind nicht nur bei Erstmontage durch den Lieferanten des Getriebeverdichters von Vorteil, sondern besonders vorteilhaft für Wartungsvor¬ gänge, die ebenfalls eine Demontage des Verdichters erfordern können. Darüber hinaus ermöglichen die mit den Lagerelementen ausgestatteten Auflager bzw. Ausformungen ein Lösen des Compressor impeller and the compressor housing does not take place can, allows an assembly on the construction site with there ¬ readily available means, for example by means of a less precise car crane. These properties are advantageous not only for initial assembly by the supplier of the gear compressor, but particularly advantageous for Wartungsvor ¬ gears, which may also require disassembly of the compressor. In addition, equipped with the bearing elements support or formations allow a release of the
Verdichtergehäuses aus der Betriebsposition und ein Verschie- ben des Verdichtergehäuses, so dass bereits verschiedene Bau¬ teile des Getriebeverdichters ohne vollständige Entfernung des Verdichtergehäuses hinreichend zugänglich für Wartungsar¬ beiten werden. Auf diese Weise ist es denkbar, dass eine War¬ tung oder Inspektion des Getriebeverdichters ohne entspre- chende Hebevorrichtung stattfinden kann. Der erfindungsgemäßen Gleitlagung erlaubt eine Bewegung des Verdichtergehäuses aus einer Betriebsposition heraus in eine Serviceposition, in der das Verdichterlaufrad bzw. der Verdichterimpeller von außen für Wartungszwecke zugänglich ist und ein Verfahren des Verdichtergehäuses aus dieser Serviceposition heraus in die Betriebsposition. Compressor housing from the operating position and a displacement of the compressor housing, so that already various Bau ¬ parts of the gear compressor without complete removal of the compressor housing are sufficiently accessible for Wartungsar ¬ pages. In this way, it is conceivable that a War ¬ tion or inspection of the gear compressor can take place without a corresponding lifting device. The sliding bearing according to the invention allows a movement of the compressor housing from an operating position out into a service position in which the compressor impeller or compressor impeller is accessible from the outside for maintenance and a method of the compressor housing from this service position out into the operating position.
Eine bevorzugte Weiterbildung der Erfindung sieht vor, dass der Getriebeverdichter zwei Lagerelemente umfasst, nämlich ein erstes Lagerelement zwischen einer erste Anformung an dem Verdichtergehäuse und einer erste Auflage des Getriebever¬ dichters sowie ein zweites Lagerelement zwischen einer zwei¬ ten Anformung und einer zweiten Auflage des Getriebeverdichters. Diese beiden Lagerelemente ermöglichen jeweils eine Be- wegung des Verdichtergehäuses in Richtung der Rotationsachse des Impellers und sind bevorzugt radial beabstandet angeord¬ net, wobei die radiale Beabstandung derart orientiert ist, dass es einen Horizontalabstand zwischen der Rotationsachse und den Gleitlagern gibt, wobei auf jeder horizontalen Seite der Rotationsachse ein Lagerelement vorgesehen ist. Eine der¬ artige Anordnung verhindert zuverlässig ein Kippen des A preferred development of the invention provides that the gear compressor comprises two bearing elements, namely a first bearing element between a first Anformung on the compressor housing and a first edition of Getriebever ¬ poet and a second bearing element between a two ¬ th molding and a second edition of the gear compressor , These two bearing elements each allow a movement of the compressor housing in the direction of the axis of rotation of the impeller and are preferably radially spaced angeord ¬ net, wherein the radial spacing is oriented such that there is a horizontal distance between the axis of rotation and the plain bearings, wherein on each horizontal Side of the axis of rotation a bearing element is provided. A ¬ such arrangement reliably prevents tilting of the
Verdichtergehäuses um eine Achse parallel zur Rotationsachse und dient naturgemäß der vertikalen Abstützung der Gewichts¬ kraft des Verdichtergehäuses. Compressor housing about an axis parallel to the axis of rotation and naturally serves the vertical support of the weight ¬ force of the compressor housing.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass die Lagerelemente jeweils mindestens ein Fixierelement auf¬ weisen, mittels dessen die Axialposition feststellbar ist. Auf diese Weise können die Lagerelemente nicht nur zu Monta¬ gezwecken benutzt werden, sondern auch als reguläres Auflager zum Abfangen der Gewichtskraft und etwaiger Betriebsdrehmo- mente an dem Verdichtergehäuse im Betrieb. Zweckmäßig ist das jeweilige Lagerelement mit einer Verschiebevorrichtung verse¬ hen. Die Verschiebevorrichtung kann zweckmäßig als Gewindestange mit entsprechenden Elementen in Eingriff stehen, die bevorzugt Gewindebohrungen aufweisen, so dass beispielsweise ein Drehen der Gewindestange einen axialen Versatz des An advantageous development of the invention provides that the bearing elements each have at least one fixing on ¬, by means of which the axial position is fixable. In this way, the bearing elements can be used not only for Monta ¬ purposes, but also as a regular support for capturing the weight and any operating torques on the compressor housing in operation. The respective bearing element is expediently provided with a displacement device . The displacement device can expediently be in the form of a threaded rod with corresponding elements, which preferably have threaded bores, so that, for example, turning the threaded rod causes axial displacement of the threaded rod
Verdichtergehäuses an dem jeweiligen Lagerelement bewirkt. Gleichzeitig ist eine derartige Verschiebevorrichtung mit Ge¬ windevortrieb in axialer Bewegungsvorrichtung einfach fixierbar, beispielsweise mittels Kontermuttern oder einer sonsti- gen Verdrehsicherung an der Gewindestange. Compressor housing causes the respective bearing element. At the same time such a displacement device with Ge ¬ wind propulsion in the axial movement device can be easily fixed, for example by means of lock nuts or other anti-rotation on the threaded rod.
Alternativ kann auch eine Hydraulik für den Antrieb der axialen Verschiebung vorgesehen sein.  Alternatively, a hydraulic system for driving the axial displacement may be provided.
Insbesondere bei verhältnismäßig schweren Verdichtergehäusen ist es sinnvoll, wenn die Auflager Bestandteil jeweils einer Stütze sind, die an einer Grundplatte des Getriebeverdichters sich abstützend befestigt sind, an welcher Grundplatte sich auch das Getriebe sich abstützt bzw. befestigt ist. Zweckmäßig ist das Auflager nicht direkt an einem Gehäuse des Getriebes - z.B. an einer Seitenwand - befestigt, so dass es aufgrund der Gewichtskraft des Verdichtergehäuses nicht zu einer Verformung des Getriebegehäuses und damit zu einem et¬ waigen Versatz der Verdichterwellen kommen kann. In particular, in relatively heavy compressor housings, it makes sense if the supports are each part of a support, which are attached to a base plate of the gear compressor supporting, on which base plate, the transmission is supported or attached. Suitably, the support is not directly attached to a housing of the transmission - for example on a side wall - fixed so that it can not come due to the weight of the compressor housing to a deformation of the gear housing and thus to a ¬ possible offset the compressor shaft.
Eine andere vorteilhafte Weiterbildung der Erfindung sieht vor, dass an dem Verdichtergehäuse oder der Grundplatte ver¬ tikal unter der Rotationsachse eine Mittenführung vorgesehen ist, welche mit einer an dem Getriebe oder der Grundplatte befestigten Führungsführung derart ausgebildet ist, dass eine horizontale Bewegung in radialer Richtung des Another advantageous development of the invention provides that provided ver ¬ tikal below the axis of rotation a center guide on the compressor housing or the base plate is, which is formed with a guide attached to the transmission or the base plate guide such that a horizontal movement in the radial direction of
Verdichtergehäuses blockiert ist. Eine zusätzliche Funktion dieser Mittenführung besteht vorteilhafte darin, dass die Führungsführung derart ausgebildet ist, dass eine axiale Be¬ weglichkeit der Mittenführung in der Führungsführung auf relative Wärmedehnungen der Komponenten des Getriebeverdichters beschränkt ist. Auf diese Weise ist nicht nur eine Axialbewe¬ gung des Verdichtergehäuses in größerem Ausmaß als die rela¬ tive Wärmedehnung blockiert, sondern auch verhindert, dass das Verdichtergehäuse relativ zu den übrigen Bestandteilen des Getriebeverdichters um eine Achse senkrecht zur Rotation¬ sachse drehbar bzw. kippbar ist. Das Verkippen ist deswegen verhindert, weil in Zusammenwirkung mit der axialen Fixiermöglichkeit der Gleitlager mit der Blockade einer Axialbewe¬ gung in der Mittenführung eine räumliche Dreipunkte-Fixierung des Verdichtergehäuses gegeben ist. Compressor housing is blocked. An additional function of this center guide is advantageous in that the guide guide is designed such that an axial Be ¬ mobility of the center guide in the guide guide is limited to relative thermal expansion of the components of the gear compressor. In this way is not only a Axialbewe ¬ supply of the compressor housing is blocked to a greater extent than the rela ¬ tive thermal expansion, but also prevents the compressor housing is rotatable relative to the other components of the transmission compressor about an axis perpendicular to the rotation ¬ axis or tiltable , The tilting is therefore prevented because in conjunction with the axial fixing possibility of the sliding bearing with the blockage of a Axialbewe ¬ tion in the center guide a three-point spatial fixation of the compressor housing is given.
Das erfindungsgemäße Verfahren zur Montage hat den Vorteil, dass zunächst das Verdichtergehäuse in sicherem axialen Ab¬ stand zu dem bereits an dem Getriebe mittels einer Antriebs¬ welle angebrachten Impeller mit seinen Anformungen auf die Auflager aufgesetzt werden kann. Mittels der durch das paarweise Aufsetzen der Anformungen des The inventive method for mounting has the advantage that initially the compressor housing can be placed in a safe axial Ab ¬ stand to the already attached to the gearbox by means of a drive ¬ wave impeller with its projections on the supports. By means of the pairing of the moldings of the
Getriebeverdichtergehäuses auf die Auflager unter Zwischenan¬ ordnung der erfindungsgemäßen Lagerelemente entstehenden beiden lagernden Führungen ist das Verdichtergehäuse einerseits zunächst sicher vertikal mit seiner Gewichtskraft abgestützt und andererseits in axiale Richtung bewegbar, so dass eine Axialbewegung mit fortschreitender zunehmender Umgebung des Impellers durch das Verdichtergehäuse ohne Verwendung eines besonders präzise arbeitenden Kranes möglich wird. Getriebeverdichtergehäuses on the supports under Zwischenan ¬ order of the bearing elements according to the invention resulting two bearing guides the compressor housing is firstly securely vertically supported by its weight and on the other hand movable in the axial direction, so that an axial movement with progressive increasing environment of the impeller through the compressor housing without using a particular precise working crane becomes possible.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass nach der Annäherung des Verdichtergehäuses an das Getriebe unter Lagerung mittels der Gleitlager und Erreichen der axialen Endposition die Lagerelemente mittels jeweils zugehöriger Fixiervorrichtungen in ihrer axialen Position festgestellt werden. An den Lagerelementen bzw. Gleitlagern können Vorkehrungen bzw. Formelemente ausgebildet sein, die ein Verkippen des Verdichtergehäuses senkrecht zur Rotationsachse abstüt¬ zen. Vorteilhaft ist nach der Verlagerung des An advantageous development of the invention provides that after the approach of the compressor housing to the transmission under storage by means of the sliding bearing and reaching the axial end position, the bearing elements by means of respectively associated Fixing devices are detected in their axial position. On the bearing elements or plain bearings precautions or mold elements can be formed, the Abstüt ¬ a tilting of the compressor housing perpendicular to the axis of rotation zen. It is advantageous after the relocation of
Verdichtergehäuses in die axiale Endposition vorgesehen, die¬ se eine Kippbewegung des Verdichtergehäuses während der Axi¬ albewegung verhindernden Formelemente derart zu verändern, dass die Abstützung gegen das Kippen deaktiviert ist. Bei¬ spielsweise können diese Formelemente Schrauben oder Gewinde¬ stangen aufweisen, deren Verdrehen dazu führt, dass nicht mehr gegen eine entsprechende Kippbewegung an dem Gleitlager abgestützt ist. Diese Deaktivierung der Kippverhinderung erfolgt vorteilhaft nach einem Verfahrensschritt der Fixierung einer Mittenführung vertikal unterhalb der Rotationsachse an dem Verdichtergehäuse in einer Führungsführung in axialer Richtung, so dass die Kippverhinderung von der Mittenführung im Betrieb übernommen ist. Im Folgenden ist die Erfindung anhand eines speziellen Ausführungsbeispiels hinsichtlich des Getriebeverdichters und anhand desselben Ausführungsbeispiels auch hinsichtlich des erfindungsgemäßen Montageverfahrens unter Bezugnahme auf Zeichnungen näher beschrieben. Es zeigen: Compressor housing provided in the axial end position, ¬ se to change a tilting movement of the compressor housing during the Axi ¬ albewegung preventing mold elements such that the support is deactivated against tilting. In ¬ example, these form elements may have screws or threaded rods ¬ whose twisting leads to that is no longer supported against a corresponding tilting movement of the sliding bearing. This deactivation of the tilt prevention advantageously takes place after a method step of fixing a center guide vertically below the axis of rotation on the compressor housing in a guide guide in the axial direction, so that the tilt prevention is taken over by the center guide during operation. In the following the invention with reference to a specific embodiment with respect to the gear compressor and the same embodiment with respect to the assembly method according to the invention with reference to drawings described in more detail. Show it:

Bauteile von unterge¬ ordneter Bedeutung oder ohne Bedeutung für die Erfindung sind entweder nur symbolisch angedeutet oder nicht dargestellt. Im Zusammenhang mit der Erfindung sind geometrische Angaben, wie axial, radial, Umfangsrichtung, tangential stets auf die eine Rotationsachse X eines Impellers IMPCO eines Verdichters COl bezogen - wenn nicht anders angegeben. Details of the slide bearing and center guide according to perspective III of Figure 1. Figure 1 shows a perspective schematic representation of components of the transmission compressor GCO invention, which are significant to the invention. Components of underweight body ¬ arranged significance or no significance for the invention are either only symbolically indicated or not shown. In the context of the invention, geometrical details, such as axial, radial, circumferential direction, tangential always refer to the one axis of rotation X of an impeller IMPCO of a compressor COl-unless stated otherwise.
Der in Figur 1 dargestellte Getriebeverdichter GCO umfasst ein Getriebe GE (welches nur mit einem Gehäuseunterteil wie¬ dergegeben ist) und einen hier beispielhaft wiedergegebenen Verdichter COl (der hier nur als Verdichtergehäuse CASCO und symbolisch angedeutet als Impeller IMPCO dargestellt ist) . The geared compressor GCO shown in Figure 1 comprises a gear GE (which is dergegeben only with a lower housing part as ¬) and a exemplarily reproduced compressor COl (which is here indicated only as a compressor housing CASCO and symbolically as impeller IMPCO shown).
Neben den beispielhaft dargestellten Verdichter COl werden in der Regel von dem Getriebe GE weitere Verdichter angetrieben. Bei der hier dargestellten Ausführung des Getriebeverdichters GCO ist es vorgesehen, dass neben dem dargestellten Verdichter COl ein weiterer Verdichter neben dem Getriebe GE angeordnet ist und auf der von dem Betrachter der Figur 1 abgewendeten Seite des Getriebes GE ebenfalls zwei Verdichter vorgesehen sind, wobei alle Verdichter von dem gemeinsamen Getriebe GE angetrieben werden. Wie bereits eingangs erläu¬ tert, ist es ein wesentliches Merkmal eines Getriebeverdich¬ ters GCO, dass es ein zentrales Getriebe GE gibt, welches verschiedene Abtriebswellen aufweist, die dem Antrieb ver¬ schiedener Verdichter dienen. In addition to the compressors COI shown as an example, further compressors are generally driven by the gear GE. In the embodiment of the gear compressor GCO shown here, it is provided that in addition to the illustrated compressor COl another compressor is arranged next to the gear GE and on the side facing away from the viewer of Figure 1 side of the transmission GE also two compressors are provided, all compressors be driven by the common gear GE. As already mentioned erläu tert ¬, it is an essential feature of a Getriebeverdich ¬ ters GCO that there is a central gear GE having different output shafts which serve to drive ver ¬ VARIOUS compressor.
Der Getriebeverdichter GCO weist eine Grundplatte BP auf, an der das Getriebe GE und der Verdichter COl befestigt und ver¬ tikal abgestützt sind. Ein bevorzugtes Anwendungsfeld der Er¬ findung sind Verdichter COl, die ein derart schweres The gear compressor GCO has a base plate BP, to which the gear GE and the compressor COl attached and ver ¬ tical supported. A preferred application field of the invention are ¬ He compressors COl that such a heavy
Verdichtergehäuse CASCO aufweisen, das es entweder besondere Verstärkungsmaßnahmen an dem Getriebe GE erfordern würden, würde man das Gehäuse CASCO an dem Getriebe GE direkt befes¬ tigten oder es zu Verformungen an dem Gehäuse des Getriebes GE führen, die sich ungünstig auf die korrekte Lage der Have CASCO compressor housing, which would require either special reinforcement measures on the transmission GE, one would CASCO the housing to the gear GE directly buildin ¬ saturated or deformations on the housing of the gear unit GE, which is unfavorable to the correct location of the
Abtriebswellen bzw. der Wellen der Verdichter COl auswirken würden und damit auch in dem Getriebe GE an Zahnrädern zu Eigentümlichkeiten an dem jeweiligen Tragbild der Zahnräder führen würden. Um diese Beeinträchtigungen zu vermeiden ist es in Figur 1 vorgesehen, dass das Verdichtergehäuse CASCO sich mittels Anformungen SUPCASl, SUPCAS2 vertikal an Aufla¬ gern SUP1, SUP2 beidseitig der Rotationsachse X abstützt, welcher Auflager SUP1, SUP2 sich direkt an der Bodenplatte BP abstützen und dort befestigt sind. Output shafts or the waves of the compressor COI would affect and thus would lead in the gear GE to gears to peculiarities of the respective contact pattern of the gears. To avoid these impairments it is provided in Figure 1, that the compressor housing CASCO by means projections SUPCASl, SUPCAS2 supported vertically on Aufla ¬ like SUP1, SUP2 both sides of the rotation axis X, which supports SUP1, SUP2 are supported directly on the base plate BP and there are attached.
Im Einzelnen sind in der Figur 1 die Anformungen SUPCASl, SUPCAS2 in der dargestellten Perspektive rechts der Rotationsachse X als erste Anformungen SUPCASl und links der Rotati- onsachse X als zweite Anformungen SUPCAS2 vorgesehen. Während des Montageverfahrens sind jeweils zwei erste Anformungen SUPCASl und zwei zweite Anformungen SUPCAS2, die jeweils axi¬ al hintereinander angeordnet sind, das Verdichtergehäuse CASCO vertikal abstützend im Eingriff. Diese axial doppelte Abstützung dient der Verhinderung eines Kippens des In detail, in FIG. 1, the projections SUPCAS1, SUPCAS2 in the illustrated perspective are provided on the right of the axis of rotation X as first projections SUPCAS1 and on the left of the axis of rotation X as second projections SUPCAS2. During the assembly process in each case two first projections and two second projections SUPCASl SUPCAS2 which are each arranged axi al ¬ one behind the other, the compressor housing CASCO are vertically supportingly engaged. This axially double support serves to prevent tilting of the
Verdichtergehäuses CASCO um eine Achse senkrecht zur Rotati¬ onsachse X. Um eine statische Überbestimmung in der Endposi¬ tion aus dem Zusammenwirken von Auflagen SUP1, SUP2 und Compressor housing CASCO about an axis perpendicular to Rotati ¬ onsachse X. To a static overdetermination in the Endposi ¬ tion from the interaction of constraints SUP1, SUP2 and
Anformungen SUPCASl, SUPCAS2 zu verhindern, wird von den bei- den axial hintereinander angeordneten abstützenden Forming SUPCASl to prevent SUPCAS2 is supported by the two axially arranged one after the other
Anformungen SUPCASl, SUPCAS2 entlastet durch Einfahren eines Unterstützungsstempels SST1, SST2.  Formations SUPCASl, SUPCAS2 relieved by retracting a support stamp SST1, SST2.
Die Absicherung gegen ein Verkippen des Verdichtergehäuses CASCO übernimmt stattdessen eine Führungsführung GG einer vertikal unter der Rotationsachse X befindlichen Mittenführung MGCO des Verdichtergehäuses CASCO, welche das  The safeguard against tilting of the compressor housing CASCO instead assumes a guide guide GG of a center guide MGCO of the compressor housing CASCO which is located vertically below the axis of rotation X and which carries the
Verdichtergehäuse CASCO relativ zu der Grundplatte BP bzw. dem Getriebe GE nicht nur in radialer Richtung zentriert, sondern auch eine Bewegungsfreiheit in axialer Richtung bis auf eine Wärmerelativdehnung (die zuvor rechnerisch bestimmt worden ist) einschränkt. In Zusammenwirken mit den beidseitig der Rotationsachse X befindlichen Anformungen SUPCASl, Compressor housing CASCO relative to the base plate BP and the gear GE not only centered in the radial direction, but also a freedom of movement in the axial direction to a thermal expansion (which has been previously determined mathematically) limits. In cooperation with the projections SUPCAS1 located on both sides of the axis of rotation X,
SUPCAS2 und Auflagen SUP1, SUP2 verhindert die damit verwirk- lichte Dreipunktlagerung wirksam ein Kippen des SUPCAS2 and Sup1 SUP2 SUP2 prevent the realization of light three-point bearing effectively tipping the
Verdichtergehäuses CASCO um eine Achse senkrecht zur Rotati¬ onsachse X. Im Einzelnen sieht das Montageverfahren nach der Erfindung vor, dass in einem ersten Schritt ST1 das zum Beispiel etwa 12 Tonnen schwere Verdichtergehäuse CASCO mittels eines Krans in senkrechter Ausrichtung mit den an dem Verdichtergehäuse CASCO vorgesehenen Anformungen SUPCAS1, SUPCAS2 auf den Auf- lagern SUP1, SUP2 aufgesetzt wird. Im Einzelnen wird zunächst eine jeweils als Gleitlagereinheit SUl, SU2 ausgebildete La¬ gereinheit BE an den Auflagern SUP1, SUP2 befestigt. Die Gleitlagereinheit SUl umfasst eine Gleitfläche SLS, die auf einer Kontaktfläche CSF des jeweiligen Auflagers SUP1, SUP2 zu gleiten vermag. Die Gleitlagereinheit SUl, SU2 umfasst au¬ ßerdem eine vertikale Anpassplatte VP, mittels derer die Höhenausrichtung des Verdichtergehäuses CASCO bestimmt wird. Schließlich dient ein U-förmiger Halter HO dazu, die Compressor housing CASCO about an axis perpendicular to the Rotati ¬ onsachse X. In detail, the assembly method provides according to the invention provides that in a first step ST1 that, for example, about 12-ton compressor housing CASCO provided by means of a crane in the vertical alignment with the at the compressor housing CASCO Forms SUPCAS1, SUPCAS2 are placed on supports SUP1, SUP2. Specifically, a respectively formed as a slide bearing unit Sul, SU2 La ¬ gereinheit BE is first attached to the supports SUP1, SUP2. The sliding bearing unit SU1 comprises a sliding surface SLS, which is able to slide on a contact surface CSF of the respective support SUP1, SUP2. The plain bearing unit Sul, SU2 comprises au ¬ ßerdem a vertical adjusting plate VP, by means of which the height position of the compressor housing CASCO is determined. Finally, a U-shaped holder HO is used to
Anformung SUPCAS1, SUPCAS2 unter vertikaler Zwischenanordnung der vertikalen Anpassplatte VP an der Gleitlagereinheit SUl, SU2 zu befestigen. Nach erfolgter vertikaler Absenkung des Verdichtergehäuses CASCO auf die Gleitlagereinheiten SUl, SU2 werden die Gleitlagereinheiten SUl, SU2 an den entsprechenden Auflagern SUP1, SUP2 gelöst und es erfolgt eine axiale Bewe- gung des Verdichtergehäuses CASCO auf das Getriebe GE im Rah¬ men des zweiten Schrittes ST2. Diese axiale Bewegung erfolgt mittels des als Gewindestange ausgebildeten Fixierelementes FEI, FE2 auf beiden Seiten der Rotationsachse X, wobei auf der Gewindestange des Fixierelementes FEI, FE2 Muttern ver- dreht werden, die in der jeweiligen axialen Anlage für einen Vortriebe des Verdichtergehäuses CASCO sorgen. In der axialen Endlage, in der der Impeller IMPCO radial von dem Anformung SUPCAS1, SUPCAS2 under vertical interposition of the vertical adjustment plate VP to the sliding bearing unit SUl, SU2 to attach. After the vertical lowering of the compressor housing CASCO to the slide bearing units Sul, SU2 the sliding bearing units SUL are SU2 to the corresponding supports SUP1 dissolved SUP2 and there is an axial motion of the compressor housing CASCO to the transmission GE in Rah ¬ men of the second step ST2 , This axial movement takes place by means of the fixing element FEI, FE2 formed as a threaded rod on both sides of the axis of rotation X, wherein nuts are turned on the threaded rod of the fixing element FEI, FE2, which provide for driving the compressor housing CASCO in the respective axial system. In the axial end position, in which the impeller IMPCO radially from the
Verdichtergehäuse CASCO vollständig umgeben ist, werden die Muttern an den Fixierelementen FEI dazu genutzt, die axiale Lage des Verdichtergehäuses CASCO festzulegen. Damit es nicht zu einer Überlastung der Gleitlagereinheiten SUl, SU2 kommt, können diese mittels eines - bevorzugt bereits auf der Bau¬ stelle vorhandenen - Kranes mittels an dem Verdichtergehäuse CASCO vorgesehenen Anhängeösen LH entlastet werden. Eine derartige Entlastung stellt so gut wie keine Anforderungen an die Präzision des dafür genutzten Kranes. In der axialen Endposition des Verdichtergehäuses CASCO wer¬ den die beidseitigen Gleitlagereinheiten SU1, SU2 axial mittels der Fixierelemente FEI, FE2 gesichert und zusätzlich mittels weiterer Befestigungselemente CS an den Auflagern SUP1, SUP2 befestigt. CASCO is completely enclosed in the compressor housing, the nuts on the fixing elements FEI are used to determine the axial position of the compressor housing CASCO. So that there is no overloading of the sliding bearing units SU1, SU2, they can by means of a - preferably already existing on the building ¬ - crane by means of the compressor housing CASCO provided eyelets LH be relieved. Relief of this kind makes virtually no demands on the precision of the crane used therefor. In the axial end position of the compressor housing CASCO ¬ the both-side sliding bearing units SU1, SU2 axially by means of the fixing elements FEI, FE2 and secured additionally attached to the supports SUP1, SUP2 means of further fasteners CS.
In der axialen Endlage befindet sich ein vertikal unter der Rotationsachse X am unteren Ende des Verdichtergehäuses CASCO befindlicher Mittenführungsnocken in einer ebenfalls an diesem Ort angeordneten Führungsführung GG des Getriebeverdich- ters GCO, wobei die Führungsführung GG Verstellelemente AE aufweist, die eine exakte Ausrichtung der Mittenführung MGCO in horizontaler Richtung senkrecht zur Rotationsachse X ermöglichen. Im Einzelnen sind diese Verstellelemente AE mit Gewinden stufenlos auf diese Horizontalausrichtung einstell- bar. In the axial end position, there is a center guide cam located vertically below the axis of rotation X at the lower end of the compressor housing CASCO in a guide guide GG of the transmission compressor GCO which is likewise arranged at this location, wherein the guide guide GG has adjusting elements AE which provide an exact alignment of the center guide MGCO in the horizontal direction perpendicular to the axis of rotation X allow. In detail, these adjusting elements AE with threads are infinitely adjustable to this horizontal alignment.
Zusätzlich weist die Führungsführung GG ein in axialer Richtung die Mittenführung MGCO fixierendes Joch YK auf, das mit¬ tels einer Anpassplatte AP das Spiel der Mittenführung MGCO in der Führungsführung GG in axialer Richtung auf die Erfordernisse der relativen Wärmedehnung beschränkbar macht. Mittels der unteren Mittenführung MGCO und der fixierten Gleitlagereinheiten SU1, SU2 ist das Verdichtergehäuse CASCO in drei Punkten räumlich fixiert, so dass ein ungewolltes In addition, the guide guide GG in the axial direction of the center guide MGCO fixing yoke YK, which makes ¬ the means of a matching plate AP the play of the center guide MGCO in the guide GG in the axial direction on the requirements of the relative thermal expansion limited. By means of the lower center guide MGCO and the fixed plain bearing units SU1, SU2, the compressor housing CASCO is spatially fixed in three points, so that an unintentional
Verkippen ausgeschlossen ist. Dies ermöglicht es, die Zusatzstützen SST1, SST2 derart zu verkürzen, dass diese Tilting is excluded. This makes it possible to shorten the additional supports SST1, SST2 such that these
Verkippsicherung deaktiviert ist. Anschließend wird unter an¬ derem auf der Seite des Getriebes GE das Tilt lock is disabled. Subsequently, under ¬ on the side of the transmission GE is the
Verdichtergehäuse CASCO verschlossen, so dass die Öffnung OP, durch die der Impeller IMPCO axial eingeführt worden ist, be¬ triebsfertig verschlossen ist. Closed compressor housing CASCO, so that the opening OP, through which the impeller IMPCO has been introduced axially, is ¬ ready to drive locked.
