Um zu vermeiden, daß bei Lagern von Wellen oder anderen drehenden Maschinenteilen Staub und Schmutz in das Innere des Lagers gelangt, verwendet man bisher im allgemeinen Filzringe oder andere Dichtungsmittel, welche, um sicher zu wirken, mit der Welle o. dgl. in satter Berührung stehen müssen, infolgedessen aber auch an der Berührungsstelle abgenutzt und dadurch wir-To avoid that with bearings of shafts or other rotating machine parts Dust and dirt get into the interior of the bearing, so far, felt rings or other sealing means have generally been used, which, in order to work reliably, must be in full contact with the shaft or the like, but consequently also at the point of contact worn out and
ίο kungslos gemacht werden. Ein Nachteil aller dieser Abdichtungen ist ferner die von ihnen hervorgebrachte Reibung als Energieverlust.ίο be made unconscious. A disadvantage for everyone These seals are also the friction they produce as energy loss.
Gemäß vorliegender Erfindung ist es nunIn accordance with the present invention it is now
gelungen, für empfindliche Lager; insbesondere Kugellager, einen wirksamen Schutz gegen Verschmutzen zu schaffen, auch wenn die Flächen, zwischen denen abgedichtet werden soll, ohne nennenswerten Druck und Reibung einfach dicht zusammengehalten werden. Besonders wichtige ist die neue Anordnung für Abdichtungen, welche in achsialer Richtung wirken sollen bei Wellen, die (z. B. infolge Erwärmung) sich achsial verschieben.succeeded for sensitive bearings; especially ball bearings, effective protection against To create pollution, even if the surfaces between which are sealed should simply be held tightly together without significant pressure and friction. Particularly important is the new arrangement for seals, which in the axial direction should act on shafts that shift axially (e.g. as a result of heating).
Die Erfindung macht von einer an sich bekannten Einrichtung zum Abhalten von Schmutz und Staub Gebrauch, nämlich von der Anordnung einer spiraligen oder schraubenförmigen Nut zwischen dem drehenden Maschinenteil und einer nahe an ihn herangeführten Wand, derart, daß sie infolge der Drehbewegung dem in den Zwischenraum eindringenden Schmutz eine Bewegung vom Lager weg erteilt.The invention makes of a device known per se for preventing Dirt and dust use, namely from the arrangement of a spiral or helical Groove between the rotating machine part and a wall brought close to him, so that they as a result of Rotary movement of the dirt entering the space a movement from the bearing granted away.
Bei dieser Anordnung ist gemäß der Erfindung nun entweder der drehende Maschinenteil oder der feststehende Teil, oder beide dort, wo die Nut wirkt, federnd ausgebildet oder mit besonderen, federnd an den anderen Teil angedrückten Platten ausgerüstet, so daß die Wirksamkeit der Anordnung durch Relativbewegungen der abzudichtenden Teile nicht aufgehoben wird.In this arrangement, according to the invention, either the rotating machine part is now or the fixed part, or both, where the groove acts, resilient or equipped with special, resiliently pressed plates on the other part, so that the Effectiveness of the arrangement due to relative movements of the parts to be sealed will be annulled.
In der beiliegenden Zeichnung sind schematisch zwei Ausführungsbeispiele dargestellt.Two exemplary embodiments are shown schematically in the accompanying drawing.
Gemäß Fig. 1 ist die im Lager α sich drehende Welle b mit einem Ring c ausgestattet, welcher mit möglichst wenig Spielraum einer Stirnfläche des Lagergehäuses 0. dgl. d gegenübersteht und mit einer Flachspirale e versehen ist. Der Ring c ist von Federn h beeinflußt, welche ihn auch bei Abnutzung oder bei Achsialverschiebung der Welle dicht an die andere Abdichtungsfläche anhalten.According to Fig. 1 in the bearing α rotating shaft is equipped with a ring b c, wherein like. D confronts with as little margin of an end face of the bearing housing 0. and is provided with a flat spiral e. The ring c is influenced by springs h , which hold it close to the other sealing surface even when worn or when the shaft is axially displaced.
Eine besonders einfache Einrichtung ist in Fig. 2 gezeichnet. Hier ist in eine Ringnut in einer Stirnfläche des auf der Welle b befestigten Ringes ρ die elastische, mit Spiralnut versehene Platte i eingefügt, welche auf einer ebenen Fläche einer zweiten Platte k schleift, die ebenso in die feststehende Wand I eingelassen ist.A particularly simple device is shown in FIG. Is here in an annular groove in an end face of the fixed ring b on the shaft, the elastic, provided with spiral plate ρ inserted i which k loops on a flat surface of a second plate which is also let into the fixed wall I.
Diese Anordnungen können, wie gezeichnet,These arrangements can, as shown,
dazu dienen, dem Schmutz den Eintritt in das Lager zu verwehren, während eine zweite (Schrauben-) Nut zwischen Welle und Lagerkörperbohrung (vgl. Fig. i) den Austritt des Öles vom Lager nach außen verhindert.serve to prevent dirt from entering the warehouse, while a second The (screw) groove between the shaft and the bearing body bore (see Fig. I) is the outlet of the Prevents oil from the bearing to the outside.
Es ist leicht ersichtlich, daß die neue Abdichtung sich für Lager aller Art eignet, seien es nun Gleitlager oder Kugel- oder Rollenlager. Je nach Lage des Falles wirdIt is easy to see that the new seal is suitable for all types of bearings, be it plain bearings or ball or roller bearings. Depending on the situation of the case
ίο natürlich die konstruktive Ausbildung gestaltet und angepaßt werden.ίο of course designed the constructive training and be customized.
Unerheblich ist es in jedem Falle, welcher der beiden ineinander gelagerten Teile im Räume feststeht, ob es sich also um eine in feststehendem Lager liegende Welle oder um einen um eine feststehende Welle oder Achszapfen zu drehenden Teil, z. B. eine Radnabe, handelt.In any case it is irrelevant which of the two nested parts in the It is clear whether it is a shaft lying in a fixed bearing or a a part to be rotated about a fixed shaft or journal, e.g. B. a wheel hub, acts.
Stets sollten die gemäß der Erfindung angewendeten Nuten verhältnismäßig seicht sein, so daß nicht zu befürchten ist, daß bei Stillstand der Inhalt der Nuten sich in einer der gewünschten Förderrichtung entgegengesetzten Richtung im Herabsinken bewegt.The grooves used according to the invention should always be relatively shallow, so that there is no fear that the content of the grooves will be in one of the Desired conveying direction moves in the opposite direction in the descent.
