Die Erfindung betrifft ein Wä1zlager/ insbesondere The invention relates to a rolling bearing / in particular
O Getr.lsbelager, bei dem cUiS ve: außen m das Lager gelangende Schmieröl durch ein Filtertsi gereinigt wird, das aus einer Stützschi'be und oineai oder mehreren «£.zmit verbundenen Filterelementen besteht sowie nnmi tt ?.bar ?ror dem Wälzkörporlaufraum angeordnet und an dem feststehenden Lagerring befestigt ist. O Gear oil bearing in which the lubricating oil entering the bearing from the outside is cleaned by a filter element which consists of a support slide and one or more connected filter elements and is arranged with a bar in front of the rolling element running space and is fastened to the stationary bearing ring.
Wälzlager der vorliegenden Gattung sind z. B. durch die Di-OS 20 29 429 bekannt. Diese bekannten Lager haben den Nachteil, daß das verunreinigte Schmieröl aus dem Getriebekasten oder dgl. durch die Dichtspalte der Lagerdichtungen, die auch bei längerem Betrieb durch Verschleiß von reibend angeordneten Dichtlippen entstehen, ^ in das Lager gelangen kann. Rolling bearings of this type are known, for example, from Di-OS 20 29 429. These known bearings have the disadvantage that the contaminated lubricating oil from the gearbox or the like can get into the bearing through the sealing gaps of the bearing seals, which also arise during long-term operation due to wear of the sealing lips arranged in friction.
Es ist die Aufgabe der vorliegenden Erfindung, ein Wälzlager der eingangs genannten Art zu schaffen, das nur aus einfach herstellbaren Teilen besteht, die leicht montiert werden können und dem nur gereinigtes Schmieröl von außen zugeführt wird.It is the object of the present invention to create a rolling bearing of the type mentioned at the beginning, which consists only of parts that are easy to manufacture, which can be easily assembled and to which only purified lubricating oil is supplied from the outside.
Diese Aufgabe wird dadurch gelöst, daß mit dem umlaufenden Lagerring eine Schleuderscheibe verbunden ist, die auf der den Wälzkörpern abgewandten Seite der Stützscheibe angeordnet und deren äußerer Rand im Bereich der Filterelemente vorgesehen und das Schmiermittel zu den Filterelementen hin abschleudernd angeordnet ist. This object is achieved in that a centrifugal disk is connected to the rotating bearing ring, which is arranged on the side of the support disk facing away from the rolling elements and whose outer edge is provided in the area of the filter elements and is arranged to centrifuge the lubricant towards the filter elements.
Durch diese Anordnung der Schleuderscheibe wird erreicht, daß § * kein verunreinigtes Schmieröl in das Luger eindringen kann, 'f da es schon vorher durch die Schleuderscheibe gegen die I; Filterelemente gefördert wird.This arrangement of the centrifugal disk ensures that no contaminated lubricating oil can penetrate into the Luger, 'f since it is already pumped against the filter elements by the centrifugal disk.

Das in den Figuren 1 und 2 dargestellte Radial.-Rillenkugellager mit umlaufendem Innenring 1 ist für den Einsatz in einem Getriebe (nicht gezeichnet) vorgesehen, in dem die Zahnräder mit Ul geschmiert werden. Zur Abdichtung des zunächst mit Fett geschmierten Lagers ist eine Dichtscheibe T. aus Kunststoff vorgesehen, die in einer Ringnut 3 im Außenring 4 angeordnet ist und mit einer Dichtlippe 5 an der Außenfläche 6 einer Schlauderscheibe 7 anliegt. Die Schleuderscheibe 7 ist auf dei Mantelfläche 8 des Innenringes 1 befestigt und läuft mitThe radial deep groove ball bearing with a rotating inner ring 1 shown in Figures 1 and 2 is intended for use in a gearbox (not shown) in which the gears are lubricated with Ul. To seal the bearing, which is initially lubricated with grease, a sealing disk T. made of plastic is provided, which is arranged in an annular groove 3 in the outer ring 4 and rests with a sealing lip 5 on the outer surface 6 of a centrifugal disk 7. The centrifugal disk 7 is attached to the outer surface 8 of the inner ring 1 and runs with
diesem um. Nach einer gewissen Betriebszeit ist das Schmierfett im Lager verbraucht. Außerdem ist die an der Schleuderscheibe anliegende Dichtlippe 5 durch die Schmirgelwirkung der Fremdstoffteilchen im Getriebeöl abgenutzt. Es entsteht ein Dichtspalt zwischen der Schleuderscheibe 7 und der Dichtscheibe 2, so daß verschmutztes Getriebeöl durch den Dichtspalt zur Schleuderscheibe 7 gelangt. Zwischen der Schleuderscheibe 7 und den Wälzkörpern 9 ist eine mit einem lrarral &iacgr; non 2ihonhn iff 1 Qä i/nroahana CfHf &ngr; anhoi \-ta 1 &Pgr; mi f &agr; -i nom oder mehreren in Ausnehmungen lla angeordneten Filterelementen 11 vorgesehen. Die Stützscheibe 10 ist in der Ringnut 3 des Außenringes 4 festgeklemmt und mit dem inneren Rand 12 bis auf einen Spalt auf die Mantelfläche 8 des Innenringes 1 heruntergezogen. Das verschmutzte Getriebeöl gelangt nicht in den Spalt zwischen der Stützscheibe 10 und dem Innenring 1, sondern wird vorher von der Schleuderscheibe aufgenommen und gegen die Filterelemente 11 geschleudert. Das durch die Filterelemente 11 in das Lager gelangende Getriebeöl ist gereinigt. Es wäscht das verbrauchte Schmierfett aus und schmiert das Lager. Durch die Anordnung der Filterelemente wird erreicht, daß nur geringe Mengen von Getriebeöl in das Lager gelangen können. Für den Druckausgleich im Lager sind in der Dichtscheibe 2 Ventileinschnitte 13 vorgesehen, die sich bei überdruck öffnen, so daß überschüssiges, abgeschleudertes verschmutztes Getriebeöl in das Getriebe zurückfließen kann.this. After a certain period of operation, the lubricating grease in the bearing is used up. In addition, the sealing lip 5 resting on the centrifugal disk is worn down by the abrasive effect of the foreign particles in the gear oil. A sealing gap is formed between the centrifugal disk 7 and the sealing disk 2, so that contaminated gear oil passes through the sealing gap to the centrifugal disk 7. Between the centrifugal disk 7 and the rolling elements 9 there is a filter element 11 with one or more filter elements 12 arranged in recesses 11a. The support disk 10 is clamped in the annular groove 3 of the outer ring 4 and is pulled down with the inner edge 12 to a gap on the outer surface 8 of the inner ring 1. The contaminated gear oil does not enter the gap between the support disk 10 and the inner ring 1, but is first picked up by the centrifugal disk and thrown against the filter elements 11. The gear oil that enters the bearing through the filter elements 11 is cleaned. It washes out the used grease and lubricates the bearing. The arrangement of the filter elements ensures that only small amounts of gear oil can enter the bearing. To equalize the pressure in the bearing, 2 valve cuts 13 are provided in the sealing disk. These open when there is excess pressure so that excess, thrown-off contaminated gear oil can flow back into the gear.
In den Figuren 3 und 4 ist ein Radial-Rillenkugellager mit Labyrinthuichtungen dargestellt, durch deren Dichtspalten ebenfalls kein verschmutztes Getriebeöl in das Lager gelangen kann. Auf der linken Seite des in der Figur 3 dargestellten Lagers ist eine Abdichtung dargestellt, bei der eine S-förmige Stützscheibe 14 einen mittleren axial verlaufenden Abschnitt 15 aufweist, der mit radialem Abstand A von der Bohrungsfläche des Außenringes 4 angeordnet ist und mehrere am Umfang verteilt angeordnete Öffnungen 16 aufweist. Zwischen dem axial gerichteten Abschnitt 15 der Stützscheibe 14 und der Bohrungsfläche 17 des Außenringes 4 ist ein Filterelement 18Figures 3 and 4 show a radial deep groove ball bearing with labyrinth seals, through whose sealing gaps no contaminated gear oil can get into the bearing. On the left side of the bearing shown in Figure 3, a seal is shown in which an S-shaped support disk 14 has a central axially extending section 15, which is arranged at a radial distance A from the bore surface of the outer ring 4 and has several openings 16 distributed around the circumference. Between the axially directed section 15 of the support disk 14 and the bore surface 17 of the outer ring 4, there is a filter element 18.

On the outer edge of the middle section 15 there is a radially outward-facing flange 20 which rests on the end face 21 of the outer ring 4. On the inner edge of the middle section 15 there is a radially inward-facing section 22 which, except for a clearance, rests on the outer surface 23 of an axially directed section 24 of the centrifugal disk 19. On the right-hand side of the bearing shown in Figure 3 there is a seal consisting of a support disk 25 and an L-shaped centrifugal disk 26. The support disk 25 has a conical section 27 with a number of recesses 28 distributed around the circumference, into which the filter element 29, designed as a ring, engages with corresponding projections 29a. In the support disk 25, the inner edge 30 is angled axially inwards and is drawn down to the outer surface 31 of the inner ring 1, except for a clearance. The support disk 25 forms a labyrinth seal 32 with the centrifugal disk 26. At the outer edge, the support disk 25 rests with a section 33 on the end face 34 of the outer ring 4.
