Description

Gebiet der ErfindungField of the Invention

Die Erfindung betrifft eine Messeinrichtung für Ringkolbenpressen zur Montage von Wälzlagern auf Wellen.The invention relates to a measuring device for ring piston presses for assembly from rolling bearings to shafts.

Hintergrund der ErfindungBackground of the Invention

In vielen Einbaufällen von Wälzlagern sitzen diese mit einem Presssitz auf ei­ ner Welle. Bei der Montage von Wälzlagern auf eine Welle mit konischem Sitz müssen exakte Schiebewege auf der Welle eingehalten werden, damit die ge­ wünschte Lagerluft im Betrieb des Wälzlagers erreicht wird. Dazu ist ein auf­ wendiges Messen des Verschiebeweges notwendig, da an der Ringkolben­ presse, über die die Wälzlager aufgeschoben werden, keine Messeinrichtung zum ermitteln des Verschiebeweges vorgesehen ist.In many cases where roller bearings are installed, they are press-fitted onto an egg a wave. When mounting rolling bearings on a shaft with a conical seat Exact sliding paths on the shaft must be observed so that the ge desired bearing clearance is achieved in the operation of the rolling bearing. This is an on nimble measurement of the displacement is necessary because of the ring piston press, over which the rolling bearings are pushed, no measuring device is provided to determine the displacement.

Um diese Problem zu lösen wird in in der EP 07 18 515 A1 eine Ringkolben­ presse mit integriertem Messtaster gezeigt. Der Ringkolben dieser Ringkolben­ presse wurde so gestaltet, dass der Verschiebeweg des beweglichen Kolbens an einem Ansatz mit einer Messuhr gemessen wird. Der Nachteil dieser Lösung ist, dass durch den zusätzlichen Ansatz die bestehenden Ringkolbenpressen bei diesem Verfahren nicht weiter verwendet werden können. Um diese Verfah­ ren einzusetzen, müssen dazu neue Ringkolbenpressen mit diesem Ansatz be­ schafft werden.To solve this problem, an annular piston is disclosed in EP 07 18 515 A1 press shown with integrated probe. The ring piston of this ring piston press was designed so that the displacement of the movable piston is measured on an approach with a dial gauge. The disadvantage of this solution is that the existing ring piston presses through the additional approach can no longer be used in this process. To this procedure use new ring piston presses with this approach be created.

Aufgabe der ErfindungObject of the invention

Die Aufgabe der Erfindung besteht darin, eine Messeinrichtung aufzuzeigen, die ohne Nachrüstvorgänge an allen herkömmlichen, unterschiedlich großen Ringkolbenpressen eingesetzt werden kann und mit der der Verschiebeweg des Wälzlagers bzw. Wälzlagerinnenringes gemessen werden kann. The object of the invention is to show a measuring device that without retrofitting to all conventional, different sizes Ring piston presses can be used and with which the displacement of the rolling bearing or rolling bearing inner ring can be measured.  

Beschreibung der ErfindungDescription of the invention

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnen­ den Teiles des Anspruches 1 gelöst. Die Ansprüche 2 und 3 beschreiben be­ vorzugte Ausführungsvarianten.According to the invention, this object is characterized by the features of solved the part of claim 1. Claims 2 and 3 describe be preferred design variants.

Der Vorteil dieser Lösung besteht darin, dass die Messeinrichtung axial in einer Bohrung an der Ringkolbenpresse über dem Öldruckraum angeordnet wird, so kann die Messspitze die Verschiebung des Ringkolbens im Öldruckraum direkt messen und anzeigen. So können alle Ringkolbenpressen, die im Einsatz sind, problemlos auf das neue Verfahren umgerüstet werden.The advantage of this solution is that the measuring device is axially in one Hole is arranged on the ring piston press above the oil pressure chamber, so the measuring tip can directly measure the displacement of the ring piston in the oil pressure chamber measure and display. So all ring piston presses that are in use can can be easily converted to the new process.

Die Ringkolbenpresse besitzt zwei genormte Bohrungen (eine radial und eine axial) zum Anschluss der Hydraulikleitung. Wird gemäß Anspruch 2 dazu die vorhandene genormte axiale Bohrung benutzt, muss an der Ringkolbenpresse keine Veränderung vorgenommen werden, um den Verschiebeweg messen zu können. Das Hydrauliköl wird in diesem Fall über die radial angeordnete Boh­ rung zugeführt.The ring piston press has two standardized bores (one radial and one axial) for connecting the hydraulic line. According to claim 2, the Existing standardized axial bore must be used on the ring piston press no change can be made to measure the displacement can. The hydraulic oil is in this case via the radially arranged Boh tion fed.

Gemäß Anspruch 3 wird ein Messtaster mit unterschiedlich langen Messspitzen eingesetzt. Mit diesen unterschiedlich langen Messspitzen kann der Verschie­ beweg in den unterschiedlich großen Ringkolbenpressen (jeder Wellendurch­ messer benötigt eine eigene Ringkolbenpresse) mit einer Messeinrichtung ge­ messen werden. Da die geraden, glatten Messspitzen über einen O-Ring kraft­ schlüssig in der Messeinrichtung gehalten werden, können diese unterschied­ lich langen Messspitzen ohne Rüstvorgänge gewechselt werden. Zum Wech­ selvorgang werden die Messspitzen nach vorne aus der Messeinrichtung gezo­ gen.According to claim 3, a probe with measuring probes of different lengths used. With these measuring probes of different lengths, the diff move in the different sized ring piston presses (each shaft through knife requires its own ring piston press) with a measuring device will measure. Because the straight, smooth measuring tips have an O-ring can be held conclusively in the measuring device, these can differ long measuring tips can be exchanged without setup. To switch the measuring tips are pulled forward out of the measuring device gene.

Kurze Beschreibung der ZeichnungBrief description of the drawing

Fig. 1 zeigt eine Ringkolbenpresse mit angeordneter Messeinrichtung im Schnitt. Fig. 1 shows an annular piston press with an arranged measuring device in section.

Ausführliche Beschreibung der ZeichnungDetailed description of the drawing

In der Fig. 1 wird die Ringkolbenpresse 1 auf die Welle 8 aufgeschraubt und drückt das Wälzlager 9 in axialer Richtung auf den Kegelsitz. Über die Öff­ nung 7, die in radialer Richtung auf der Ringkolbenpresse angeordnet ist, wird das Hydrauliköl zugeführt (Stand der Technik). In die axiale Öffnung 6 wird die Messeinrichtung 10 angeordnet. Hierbei wird das Teil 11 in das genormte Ge­ winde, das als Anschluß für eine Hydraulikleitung vorgesehen ist, einge­ schraubt. Die Messspitze 20 liegt dann mit Druck an der Stirnseite 3 des be­ weglichen Kolbens 2 der Ringkolbenpresse 1 an. Der Druck für die Messspitze 20 wird über die Feder 13 erzeugt. Die Bewegung der Messspitze 20 wird über das Teil 12 auf die Messuhr 16 übertragen. Die Messuhr 16 zeigt somit die axiale Bewegung des Kolbens 2 und damit des Innenringes 9a des Wälzla­ gers 9 an. Die Messspitze 20 ist über den O-Ring 21 im Gehäuse abgedichtet und wird über diesen O-Ring 21 gleichzeitig kraftschlüssig gehalten. Im ausge­ bauten Zustand der Messeinrichtung 10 kann die Messspitze 20 axial nach vorne abgezogen werden, um eine andere Messspitze 20 einzusetzen.In FIG. 1, the hydraulic nut 1 is screwed onto the shaft 8 and pushes the rolling bearing 9 in the axial direction on the conical seat. Via the opening 7 , which is arranged in the radial direction on the ring piston press, the hydraulic oil is supplied (prior art). The measuring device 10 is arranged in the axial opening 6 . Here, part 11 is screwed into the standardized Ge thread, which is provided as a connection for a hydraulic line. The measuring tip 20 is then pressurized on the end face 3 of the movable piston 2 of the ring piston press 1 . The pressure for the measuring tip 20 is generated via the spring 13 . The movement of the measuring tip 20 is transmitted to the dial gauge 16 via the part 12 . The dial gauge 16 thus shows the axial movement of the piston 2 and thus the inner ring 9 a of the Wälzla gers 9 . The measuring tip 20 is sealed in the housing via the O-ring 21 and is held non-positively at the same time via this O-ring 21 . When the measuring device 10 has been removed, the measuring tip 20 can be pulled off axially to the front in order to use a different measuring tip 20 .
