Description

Die Erfindung- bezieht -sich auf eine Vorrichtung, die das Aufschrumpfen und das Lockern von Wellenbunden oder aufgesetzten Ringen erleichtern soll. Insbesondere ist als Anwendungsgebiet für die Erfindung an ein Wälzlager gedacht, wie solche in der Ausbildung bekannt sind, daß sie als Ganzes auf die zu lagernde Welle aufgeschoben werden, und wobei dann der äußere Lagerteil lösbar am Maschinengehäuse befestigt wird.The invention relates to a device that the shrinking and to facilitate the loosening of shaft collars or attached rings. In particular is intended as a field of application for the invention on a roller bearing, such as such are known in training that they are pushed as a whole onto the shaft to be supported are, and then the outer bearing part is releasably attached to the machine housing will.

Die Besonderheit wird darin gesehen, daß' in ilem Ring oder Bund eine elektrische Heizquelle, zweckmäßig eine Widerstandsheizung, in konzentrischer Einlagerung untergebracht ist, die durch einen Stecker o. dgl. Kontakt mit einer elektrischen Anschlußleitung in Verbindung gebracht werden kann..The peculiarity is seen in the fact that 'in a ring or covenant one electrical heating source, expediently a resistance heating, in concentric storage is housed, which by a plug o. The like. Contact with an electrical Connection line can be connected ..

An Hand der Zeichnung ist die Verwendungsmöglichkeit der Erfindung an einer Rollenlagerung gezeigt, wie solche z. B. bei Wälzgerüsten für Drahtwalzwerke Anwendung finden.The possible uses of the invention are shown in the drawing shown on a roller bearing, such as such. B. in rolling stands for wire rod mills Find application.

Das Rollenlager ist durch i angedeutet; es ist auf den Zapfen 2 der angedeuteten Walze 3 aufgesetzt und besteht im wesentlichen aus den Laufkränzen 4 und@5 ,für die mit 6 und 7 bezeichrieten Walzkörper (konischen Rollen).The roller bearing is indicated by i; it is on the pin 2 of the indicated roller 3 and consists essentially of the running rings 4 and @ 5, for the roller bodies (conical rollers) denoted by 6 and 7.

Die das Lagergehäuse 8 stirnseitig abschließende Scheibe 9 umfaßt abdichtend den auf den Wellenstumpf aufgeschrumpften Ring io, der den inneren Wälzlagerkranz 5 axial abstützt. Der Ring io ist dabei hohl gehalten und von außen zugänglich, aber durch eine Ringscheibe i i abgeschlossen. Im Innern des Ringes io befindet sich konzentrisch eingelagert eine elektrische Widerstandsheizung 12. Wird diese unter Strom gesetzt, so kann nach entsprechender Erwärmung des Ringes io dieser infolge der eingetretenen Wärmedehnung leicht von der Welle abgezogen bzw. umgekehrt aufgezogen werden. Im letzteren Falle schrupmft sich nach eingetretener Erkaltung der Ring auf seiner Welle auf.The disk 9 which closes off the bearing housing 8 at the end face comprises sealing the ring shrunk onto the stub shaft, which forms the inner roller bearing ring 5 is supported axially. The ring io is kept hollow and accessible from the outside, but closed by an annular disk i i. Located inside the ring io an electrical resistance heater 12 embedded concentrically. If this energized, so after appropriate heating of the ring io this as a result of the thermal expansion that has occurred, it is slightly pulled off the shaft or vice versa be raised. In the latter case, it shrinks after it has cooled down the ring on its shaft.
