Vorrichtung zum Zentrieren von Wellen in LagernDevice for centering shafts in bearings

Die Erfindung betrifft eine Vorrichtung zum Zentrieren von Wellen, insbesondere Gleitlagerwellen, in Lagern. Sie ist auch für Montage-, Transport- und Ausrichtungszwecke benutzbar.The invention relates to a device for centering Shafts, especially plain bearing shafts, in bearings. It can also be used for assembly, transport and alignment purposes.

Zur Zentrierung horizontal und senkrecht angeordneter Wellen, z.B. Gleitlagerwellen, ist es üblich, in den Gehäuseaußenwänden an den Wellenaustrittsstellen Zentrierringe einzubauen. Solche Zentrierringe sind häufig- zweiteilig und müssen für ,jede Durchmessergröße passend hergestellt werden. Sie sind in einer Nut eingesetzt und mit mehreren Schrauben am Gehäuse befestigt. Diese Ringe sind in der Herstellung aufwendig und ihre Verwendung erfordert bei der Montage und Demontage einen großen Zeitaufwand. Beim Einsatz dieser Ringe ist es nicht möglich, die Welle ohne zusätzliche Werkzeuge und Hebevorrichtungen zu drehen. Andererseits besteht die Gefahr, daß die Welle durch Schleifen beschädigt wird.To center horizontally and vertically arranged shafts, for example plain bearing shafts, it is common to install centering rings in the outer housing walls at the shaft exit points. Such centering rings are often in two parts and must be made to fit each diameter size. They are inserted in a groove and attached to the housing with several screws. These rings are complex to manufacture and their use requires a great deal of time during assembly and disassembly. When using these rings, it is not possible to turn the shaft without additional tools and lifting devices. On the other hand, there is a risk that the shaft will be damaged by grinding.

Aufgabe der Erfindung ist es, die bekannten Mängel abzustellen und eine Zentrier-, Montage-, Transport-, Ausrichtungs- und Sicherheitsvorrichtung zu schaffen, die ohne größeren Bearbeitungsaufwand unabhängig von Wellendurchmesser und Wellendrehrichtung auf einfache Weise verwendet werden kann.The object of the invention is to remedy the known deficiencies and a centering, assembly, transport, alignment and To create a safety device that is independent of the shaft diameter and direction of rotation without major machining effort can be used in a simple manner.

Die Lösung der Aufgäbe.erfolgt dadurch, daß das Lagergehäuse an seinen Stirnseiten/eine ringförmige, zur Wellerinitte und zur Stirnseite hin offene, zentrische Eindrehung aufweist, in der eine Rollenkette angeordnet ist, die in der Eindrehung ihre Laufbahn hat und die Welle trägt.The solution to the task is achieved in that the bearing housing at its end faces / an annular one, to the shaft line and to the front side has open, central recess in which a roller chain is arranged, which in the recess has its career and carries the wave.

Es ist weiter vorgesehen, daß die Rollenkette gegen axiale Bewegung auf der Welle gesichert ist.It is further provided that the roller chain is secured against axial movement on the shaft.

Die Rollenketten können in dem Wellendurchmesser in etwa entsprechenden Längen in die Stirnseite der Gehüuse eingesetzt v/erden. Sie können einseitig oder beidseitig, in einfacher oder mehrfacher Rollenkettenausführung verwendet v/erden.The roller chains can be approximately in the shaft diameter corresponding lengths inserted into the front of the housing. You can be unilateral or bilateral, in simpler or multiple roller chain designs are used.

Die gehärteten Rollenketten sind handelsübliche Ketten, deren Rollendurchmesser größer als die Verbindungsglieder sind. Sie werden in Nuten in die Gehäusestirnseiten eingebaut und mittels Schellen oder dergl. gegen ein axiales Verschieben gesichert. Die Welle wird zentriert und dabei von den Rollen getragen. Während der Montage von Lagern kann es erforderlich werden, die Wellen in den Lagern 2u drehen, damit beispielsweise bei Schubwellen die einzelnen Schubstücke durch Öffnungen in das Gehäuse eingesetzt werden können. Das Drehen der Lagerwelle kann dann bei eingebauter Rollenkette ohne Mühe, ohne mechanische oder hydraulische Vorrichtungen und ohne Beschädigung der Welle oder des Gehäuses mit geringer Kraft, gegebenenfalls mit Handkraft, erfolgen.The hardened roller chains are commercially available chains with a roller diameter larger than the connecting links. she are installed in grooves in the front sides of the housing and secured against axial displacement by means of clamps or the like. The shaft is centered and carried by the rollers. During the assembly of bearings it may be necessary to rotate the shafts in the bearings 2u, so that, for example, in the case of shear shafts, the individual thrust pieces through openings can be used in the housing. With the roller chain installed, the bearing shaft can then be turned without any effort, without mechanical or hydraulic devices and without damaging the shaft or the housing with little force, if necessary by hand.

Beim Transport des Lagers mit der Welle wird die Welle ebenfalls von der Rollenkette getragen, um so Gehäuse und Welle vor Transportschäden zu bewahren.When the bearing is transported with the shaft, the shaft is also carried by the roller chain so that the housing and shaft are in front To preserve transport damage.

Bei Verwendung der Vorrichtung an Bord von Schiffen können für das Kuppeln der gesamten Wellenleitung die einzelnen Wellen in der Lagern mühelos, gegebenenfalls ohne Drehvorrichtung, in die gewünschte Stellung gebracht werden. Nach dem Ausrichten der Wellen und vor dem endgültigen Kuppeln derselben, müssen die Rollenketten ausgebaut werden, um die Lagergehäusestirnseiten zu entlasten.When using the device on board ships you can For coupling the entire shaft line, the individual shafts in the bearings effortlessly, if necessary without a rotating device, in be brought to the desired position. After aligning the shafts and before finally coupling them, you must the roller chains are removed to relieve the bearing housing faces.

Die Vorteile der erfindungsgenäßen Vorrichtung liegen insbesondere in der einfachen und wirtschaftlichen Herstellung und ihrer jederzeitigen und wirkungsvollen Wiederverwendung.The advantages of the device according to the invention are in particular in the simple and economical production and their effective reuse at any time.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Es zeigen:In the drawing, the subject matter of the invention is in one embodiment shown. Show it:
