KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist eine bekannte Tatsache, daß Spindellager an Werkzeug- und anderen Maschinen nur dann ruhig und genau arbeiten, wenn neben der guten Auflage der Lauffläche das sogenannte Lagerfutter oder die Lagerbüchse fest an den Lagerkörper anliegt.It is a known fact that spindle bearings on machine tools and other machines Only work calmly and precisely if, in addition to the good support of the tread, this so-called bearing chuck or the bearing bush rests firmly on the bearing body.
Um beides zu erreichen, sind heute die meisten Lager an Werkzeugmaschinen so ausgeführt, daß die Lauffläche der Spindel zylindrisch ist, während die Nachstellbarkeit durch den Außenkonus der Lagerbüchse mittels zweier Ringmuttern bewirkt wird.In order to achieve both, most machine tool bearings today are designed to that the running surface of the spindle is cylindrical, while the adjustability through the outer cone of the bearing bush is effected by means of two ring nuts.
Die außen konisch gearbeitete LagerbüchseThe bearing bush with a conical shape on the outside
ist bekanntlich einmal durchgehend geschlitzt und von außen bis zu einer bestimmten Tiefe - mit mehreren Nuten versehen, durch welche eine gute Anlegefläche am Außenkörper beim Nachstellen der Lager erreicht werden soll.is known to be fully slotted once and from the outside to a certain depth - Provided with several grooves, through which a good contact surface on the outer body when Readjusting the bearings is to be achieved.
Der äußere Anpressungsdruck ist nun hierbei stets von der auftretenden elastischen Materialspannung abhängig; es ist die Einstellung daher schwierig und ungenau. The external contact pressure is now always dependent on the elastic one that occurs Material tension dependent; therefore, the adjustment is difficult and imprecise.
Wird nun einmal die Elastizitätsgrenze überschritten, so wirkt das Lager klemmend auf die Lauffläche und kann nicht die nötige Erweiterung der Bohrung erhalten.If the elastic limit is exceeded, so the bearing has a clamping effect on the running surface and cannot do the necessary expansion the bore received.
Gegenstand der Erfindung ist eine Vorrichtung, durch welche das Lagerfutter auch' ohne Inanspruchnahme seiner Elastizität je nach Erfordern erweitert wird, und zwar geschient das mittels eines Keiles o. dgl. Die Lagerbüchse kann dadurch sehr-leicht paarschlüssig erweitert werden, so daß sie vollkommen fest an den Lagerkörper gepreßt wird, ohne klemmend auf die Lagerstelle zu wirken.The subject of the invention is a device by which the bearing chuck also ' without making use of its elasticity is expanded as required, namely splinted that by means of a wedge or the like. The bearing bush can thereby very easily be paired be expanded so that it is pressed firmly against the bearing body, without jamming the bearing point.
Aus beiliegender Zeichnung ist die Wirkungsweise, des Nachstellens ersichtlich. Das mehreremal genutete und einmal geschlitzte außen konische Lagerfutter α ist an der Schlitzstelle keilartig ausgefräst. In diese keilartige Ausfräsung wird der Keil b, der mit einer Nase versehen ist, eingelegt. Vermittels einer Schraube c wird der Keil b in der durch beide Ringmuttern d gehaltenen Lagerbüchse verschoben und dadurch der äußere Umfang erweitert, wodurch die denkbar festeste Anlagefläche erzielt wird, auch wenn das Lager infolge unsachgemäßer Verstellung nicht richtig nachgezogen wurde.The mode of operation of the adjustment can be seen in the accompanying drawing. The outer conical bearing chuck α , grooved several times and slotted once, is milled out like a wedge at the slot point. The wedge b, which is provided with a nose, is inserted into this wedge-like milled recess. By means of a screw c , the wedge b is displaced in the bearing bush held by both ring nuts d, thereby expanding the outer circumference, which results in the most solid contact surface imaginable, even if the bearing was not properly tightened due to improper adjustment.
An Stelle des Keils kann auch ein anderes keilartiges Element verwandt werden.Instead of the wedge, another wedge-like element can also be used.
