Description

Einrichtung zur Verminderung des Laufgeräusches bei Wälzlagerungen. Rasch laufende Maschinen zeigen in der Regel ein beträchtliches Laufgeräusch, das an einem gewissen Teil auf Luftwirbelung, Gleitreibung von Schleifringen u. dgl., zum anderen Teil aber auch .auf die Art und Ausführung der Lagerung zurückzuführen ist. Letzterem liegt der Vorgang zugrunde, daß vorwiegend nicht ausgewuchtete Massen sowie Ungenauigkeiten in der Lageranordnung den sich drehenden Körper zu einem schwingenden System machen. Die rasch wechselnden Schwingungen verursachen entsprechende Veränderungen in den Lagerelementen, die sich wieder dort als Laufgeräusch auswirken.Device to reduce the running noise with roller bearings. Fast-running machines usually make a considerable amount of running noise, the to a certain extent on air turbulence, sliding friction of slip rings and the like, on the other hand, it is also due to the type and design of the storage is. The latter is based on the process that predominantly unbalanced masses and inaccuracies in the bearing arrangement turn the rotating body into a vibrating one system do. The rapidly changing vibrations cause corresponding ones Changes in the bearing elements, which again have an effect there as running noise.

Beim Gleitlager ,äußert sich meist das, Laufgeräusch als ein Brummen, das um so,geringerwird, je geringer die Lagerluft und je besser die Schmierung ist, da eine genügend dichte ölhaut zwischen Zapfen und Lager als dämpfendes Polster wirkt. -Beize Wälzlager, das für rasch laufende Maschinen vorwiegend in Betracht kommt, liegen die Verhältnisse insofern ungünstiger, als statt des ölpolsters zwischen festem und sich drehendem Teil Kugeln oder Rollen angeordnet :sind, die ihre Laufbahnen mit wesentlich höherer Pressung belasten, so daß sich an den Berührflächen keine ölscbicht mehr halten kann. Irgendwelche Schwingungen wirken daher beim Wälzlager viel unmittelbarer und müssen sich entsprechend nachteiliger bemerkbar machen. Diese unangenehme Nebenwirkung wird insbesondere bei Vorhandensein von radialer und achsialer Luft, welche die Wälzkörper aus verschiedenen Gründen zwischen den Laufbahnen haben müssen, begünstigt.In the case of plain bearings, the running noise is usually expressed as a humming, which becomes smaller, the smaller the bearing clearance and the better the lubrication, there is a sufficiently dense oil skin between the pin and the bearing as a cushioning cushion works. -Beize rolling bearings, which are primarily intended for high-speed machines comes, the circumstances are so far more unfavorable, as instead of the oil cushion between fixed and rotating part balls or rollers are arranged: which are their raceways load with much higher pressure so that there are no oil layer can hold longer. Any vibrations therefore act on the rolling bearing much more directly and must make themselves noticeably more disadvantageous. These unpleasant side effect becomes especially in the presence of radial and axial Air that the rolling elements have between the raceways for various reasons must, favors.

Den oben dargestellten Schwierigkeiten kann man aus dem Wege gehen, wenn beispielsweise der stillstehende Laufring eines Kugellagers lose verschiebbar in das Gehäuse gesetzt und von einer Seite in Längsrichtung nachgiebig belastet wird, vorausgesetzt, daß die Größe dieser zusätzlichen Belastung richtig getroffen wird. Da diese richtige Belastung selbst bei Lagerungen gleicher Art und Größe ganz verschiedene Größe haben kann, genügt die bei Walzlagexn schon bekannte Anordnung einer oder mehrerer in achsialer Richtung auf einen Laufring wirkenden Federn nicht, sondern es ist notwendig, daß die richtige Zusatzbelastung während des Betriebes so lange verändert werden kann, bis die" richtige Größe gefunden ist.The difficulties presented above can be avoided, if, for example, the stationary race of a ball bearing is loosely displaceable placed in the housing and resiliently loaded from one side in the longitudinal direction is provided that the size of this additional burden is properly met will. Because this correct load even with bearings of the same type and size can have different sizes, the arrangement already known in the case of Walzlagexn is sufficient one or more springs acting axially on a race ring do not, rather it is necessary that the correct additional load during operation can be changed until the "correct size" is found.

Die Einrichtung zur Veränderung der Zusatzbelastung wird zweckmäßig mit einem geeigneten Anschlag o. dgl. ausgerüstet, der verhindert, daß die Zusatzbelastung zu hochgemacht wird.The device for changing the additional load becomes appropriate Equipped with a suitable stop or the like, which prevents the additional load is made too high.

Als Ausführungsbeispiel zeigt die Zeichnung im Achsialschnitt ein Kugellagerpaar, auf dessen linker Seite die Erfindung angewendet ist.As an exemplary embodiment, the drawing shows an axial section Ball bearing pair, on the left side of which the invention is applied.

Fähe Welle wist an beiden Enden in Kugellagern g bzw. h gelagert. Der Außenring des Lagers g liegt lose im Gehäuse und ist mittels eines Belastungsgewichtes b sowie des um den - Stift i schwingbaren Hebels c und der verschiebbaren Büchse d in Längsrichtung einseitig belastet. Dadurch kommt eine Zusatzbelastung auch des Kugellagers. h zustande; so daß die Kugelaa beider Lager satt zwischen den Laufrillen anliegen und irgendwelche Schwingungen des gelagerten - Systems. nicht aufkommen können.The next shaft is supported at both ends in ball bearings g and h. The outer ring of the bearing g lies loosely in the housing and is by means of a loading weight b as well as the lever c, which can swing around the pin i, and the sliding sleeve d loaded on one side in the longitudinal direction. This also creates an additional burden for the Ball bearing. h come about; so that the Kugelaa of both bearings is full between the grooves and any vibrations in the stored system. not come up can.

Das Belastungsgewicht b ist auf dem Hebel c verschraubbar, so daß es während des Laufes der Lagerung verstellt werden kann. Im letzteren Fall kann die Zusatzbelastung an die Art und Größe der vorhandenen Schwingungen angepaßt und dadurch eine entsprechende Verminderung oder Beseitigung des Laufgeräusches erreicht werden.The loading weight b can be screwed onto the lever c so that it can be adjusted during storage. In the latter case, can the additional load is adapted to the type and size of the existing vibrations and thereby a corresponding reduction or elimination of running noise is achieved will.

Als Belastungsmittel könnte an Stelle eines Gewichtshebels auch eine Feder oder ein System von Federn angewendet werden oder nachgiebige Zwischenglieder beliebiger anderer Art, wie z. B. pneumatische und hydraulische Vorrichtungen, Gummi und ähnliche Stolte.Instead of a weight lever, a Spring or a system of springs are used or flexible intermediate links of any other kind, such as B. pneumatic and hydraulic devices, rubber and similar stolts.

Es können auch auf Magnetismus oder Fliehkraftwirkung begründete Anordnungen eingebaut werden.Arrangements based on magnetism or centrifugal force can also be used to be built in.
