Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Verfahren zur Montage eines Lagersatzes einer Wälzlagerung auf der Rotorwelle beispielsweise eines Schraubenverdichters.The invention relates to a method for mounting a bearing set of a rolling bearing on the rotor shaft, for example a screw compressor.

Der Nachteil derartiger Lösungen ist darin zu sehen, dass sich das Axialspiel über die Betriebsdauer verändern kann, da Tellerfedern auf Dauer ermüden. Daher wird eine Verbesserung von Lagersätzen und entsprechender Montageverfahren angestrebt, die herkömmliche Montageeinrichtungen nutzen.The disadvantage of such solutions can be seen in the fact that the axial play can change over the operating time, as disc springs tire in the long run. Therefore, an improvement of bearing sets and corresponding assembly methods is sought, use the conventional mounting equipment.
Es ist allgemein übliche Praxis, dass Hersteller von Schraubenkompressoren die Messung des Spaltes zwischen Rotor und Gehäuse bei der Montage in vertikaler Rotorposition durchführen. Diese Vorgehensweise ist bei Verwendung von Kugellagern als Axiallager unproblematisch, da Kugellager in der Lage sind, die bei der Messung in vertikaler Position auftretenden hohen Axialkräfte aufzunehmen. Nimmt jedoch ein Zylinderrollenlager Axialkräfte auf, so kommt es aufgrund der fehlenden Radiallast zu einer Verkippung der Rollen während der Messung. Diese Verkippung führt zu einem Messfehler, da die Welle sich hierdurch weiter verschieben lässt als dies ohne Verkippung möglich wäre.It is common practice for screw compressor manufacturers to measure the gap between rotor and housing when mounted in vertical rotor position. This procedure is unproblematic when using ball bearings as thrust bearings, since ball bearings are able to absorb the high axial forces occurring during the measurement in a vertical position. However, if a cylindrical roller bearing absorbs axial forces, then due to the lack of radial load, the rollers will tilt during the measurement. This tilting leads to a measurement error, since the wave can thereby be further shifted than would be possible without tilting.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Montage eines Lagersatzes auf der Rotorwelle beispielsweise eines Schraubenverdichters vorzustellen, welches die geschilderten Nachteile nicht aufweist. Das Verfahren zur Montage des Lagersatzes soll eine präzise Einstellung eines axialen Abstandes des Lagersatzes zu einer Rotorwelle ermöglichen.The invention has for its object to provide a method for mounting a bearing set on the rotor shaft, for example, a screw compressor, which does not have the disadvantages described. The method for mounting the bearing set to allow precise adjustment of an axial distance of the bearing set to a rotor shaft.
Zusammenfassung der ErfindungSummary of the invention
Die Lösung dieser Aufgabe wird mittels eines Verfahrens mit den Merkmalen des Anspruchs 1 erreicht. Vorteilhafte Weiterbildungen dieses Verfahrens sind in den Ansprüchen 2 bis 5 definiert.The solution of this problem is achieved by means of a method having the features of
Die Erfindung geht aus von einem Verfahren zur Montage eines Lagersatzes auf der Rotorwelle beispielsweise eines Schraubenverdichters, bei dem in einem ersten Schritt der aus Kugellager und Zylinderrollenlager bestehende Lagersatz auf eine vertikal angeordnete Rotorwelle aufgeschoben und die Rotorwelle mit einer vertikalen Kraft belastet wird, und bei dem ein axialer Abstand des Rotors zur Gehäusestirnwand und/oder der Abstand wenigstens der Innenringe des Lagersatzes zu einer Anlauffläche der Rotorwelle gemessen wird, und bei dem in einem zweiten Schritt der Lagersatz von der Rotorwelle entfernt und nach Demontage des Lagersatzes dieser zur Korrektur des axialen Abstandes bearbeitet wird, und bei dem in einem dritten Schritt der bearbeitete Lagersatz auf die Rotorwelle aufgeschoben und mit dieser endgültig verbunden wird.The invention is based on a method for mounting a bearing set on the rotor shaft, for example a screw compressor, in which the bearing set consisting of ball bearings and cylindrical roller bearings is pushed onto a vertically arranged rotor shaft and the rotor shaft is loaded with a vertical force, and in the first step an axial distance of the rotor to the housing end wall and / or the distance of at least the inner rings of the bearing set is measured to a contact surface of the rotor shaft, and in which removed in a second step, the bearing set of the rotor shaft and machined after disassembly of the bearing set for correcting the axial distance is, and in which in a third step, the processed bearing set is pushed onto the rotor shaft and finally connected to this.
Zudem ist vorgesehen, dass im ersten Schritt ein einstückiger Massring oder ein Satz von Messscheiben in das Zylinderrollenlager anstelle der Zylinderrollen zwischen Außenring und Innenring eingesetzt wird (Rollenverkörperungsring), wobei die axiale Breite des Massrings bzw. der Messscheiben der axialen Breite der Zylinderrollen entspricht, wonach der Lagersatz auf die vertikal angeordnete Rotorwelle aufgeschoben wird, und dass im dritten Schritt der bearbeitete Lagersatz mit den Zylinderrollen versehen sowie auf die Rotorwelle aufgeschoben und mit dieser endgültig verbunden wird.In addition, it is envisaged that in the first step, a one-piece ring or a set of measuring disks in the cylindrical roller bearing between the outer ring and inner ring is used instead of the cylindrical rollers (Rollenverkörperungsring), wherein the axial width of the ground ring or the measuring disks corresponds to the axial width of the cylindrical rollers, after which the bearing set is pushed onto the vertically arranged rotor shaft, and that in the third step, the processed bearing set provided with the cylindrical rollers and pushed onto the rotor shaft and finally connected to this.
Ein derartiges Verfahren bietet ganz erhebliche Vorteile gegenüber den bislang bekannten Verfahren. Bisher erfolgt die Montage des Lagersatzes in zwei Schritten. Im ersten Schritt wird danach zunächst das Axialspiel im Lagersatz gemessen und die passende Passscheibe zur Axialspieleinstellung ausgewählt. Im zweiten Schritt erfolgt die Einstellung des Spaltes zwischen Rotor und Gehäuse. Das Aggregat wird wieder zusammengebaut, dann wird der Spalt zwischen Rotor und Gehäuse gemessen, um anschließend das Aggregat wieder zu zerlegen und die richtige Passscheibe zur Wellenjustierung einzusetzen.Such a method offers very significant advantages over the previously known methods. So far, the mounting of the bearing set is done in two steps. In the first step, the axial play is first measured in the bearing set and the matching shim is selected for axial clearance adjustment. In the second step, the gap between rotor and housing is adjusted. The unit is reassembled, then the gap between the rotor and the housing is measured in order to then disassemble the unit again and insert the correct shim for shaft adjustment.
Durch den Massring oder durch einen entsprechenden Satz von Messscheiben lässt sich auf überraschend einfache Art und Weise ein schier unüberwindbares Hindernis bei der bislang verwendeten Methode ausräumen, nämlich einen immer wieder auftretenden Messfehler, der daher rührt, dass radial unbelastete, aber axial übermäßig stark belastete Zylinderrollen um ihre Achse kippen. Dieses Verkippen führt zu einem Messfehler, der bislang nur abgeschätzt aber nicht ausgeräumt werden konnte.The mass ring or a corresponding set of measuring disks makes it possible to overcome a virtually insurmountable obstacle in the previously used method, namely a recurrent measuring error, which is due to the fact that radially unstressed but axially excessively heavily loaded cylindrical rollers tilt around its axis. This tilting leads to a measurement error that was previously estimated but could not be eliminated.
Außerdem kann in einer Weiterbildung des erfindungsgemäßen Verfahrens vorgesehen sein, dass im zweiten Schritt wenigstens ein gemessener axialer Überstand einer Stirnkante gegenüber einer radial beabstandeten Stirnkante von Außenring bzw. Innenring des Zylinderrollenlagers reduziert wird.In addition, it can be provided in a development of the method according to the invention that in the second step, at least one measured axial projection of a front edge relative to a radially spaced end edge of the outer ring or inner ring of the cylindrical roller bearing is reduced.
In einer besonders praktischen Weiterbildung des erfindungsgemäßen Verfahrens ist vorgesehen, dass im zweiten Schritt die mit den Borden versehenen Stirnkanten von Außenring und Innenring auf eine plane Fläche aufgestellt und die axial gegenüberliegenden Stirnkanten zum Abtrag des Überstandes in einem Arbeitsgang schleifend bearbeitet werden.In a particularly practical development of the method according to the invention, it is provided that in the second step, the edge edges of the outer ring and inner ring provided with the ribs are set up on a flat surface and the axially opposite end edges are sanded to remove the overhang in one operation.
Besonders vorteilhaft ist ebenso eine Ausgestaltung des erfindungsgemäßen Verfahrens, die sich dadurch auszeichnet, dass im zweiten Schritt wenigstens ein Überstand des Innenrings des Zylinderrollenlagers mit einer Abweichung von +/–0,001 mm bis 0,008 mm, vorzugsweise von +/–0,005 mm, gegenüber dem im ersten Schritt gewonnenen Messergebnis abgetragen wird. Also particularly advantageous is an embodiment of the method according to the invention, which is characterized in that in the second step at least one projection of the inner ring of the cylindrical roller bearing with a deviation of +/- 0.001 mm to 0.008 mm, preferably of +/- 0.005 mm, compared to the first step gained measurement result is removed.
Besonders vorteilhaft ist schließlich eine Ausgestaltung des erfindungsgemäßen Verfahrens, die sich dadurch auszeichnet, dass im zweiten Schritt Überstände von Stirnkanten von Außenring und Innenring des Kugellagers verringert werden.Finally, a refinement of the method according to the invention is particularly advantageous, which is characterized in that, in the second step, projections of end edges of the outer ring and inner ring of the ball bearing are reduced.
