Description
Der nächstelhenid beschriebenien Erfindung liegt die Absicht zugrunde, mit einfachsten Mitteln einen Wälzlag-erkäfig zu schaffen, ,der einerseits das Lager selbstschxrnierend.macht, andererseits dasselbe nach außen. gleichzeitig staubdicht abschließt. Um diesen Zweck zu erreichen, wird, gemäß der Erfindung für -die Käfige ein Werkstoff verwendet, der in , der Lage ist, das Öl, welches zur Schmierung, notwen,düg ist, aufzusaugen. und: in,geri.ngen Mengen wieder während des Betriebes an die Oberflächen der Rollkörper und Rollbahnen abzugeben. Um. durch Anliegen ider Mantel- bzw. Bohrungsflächen des Käfigs an den -Borden oder anderen Flächen neben den Rollbahnen eine genügende Dichtwirkung des Käfigs zu erreichen, muß de_r Werkstoff eine gewisse Elastizität oder Zusammendrückbarkeit besitzen. Als Werkstoff wllrd:. um dieses Ziel zu erreichen, Filz vorgesehen. Der -Erfindungsgedanke beruht darauf, einen elastischen, ölaufsaugenden Werkstoff zu verwenden und die Käfige so zu gestalten, daß sie- bei Umschließung der Wälzkörper gleichzeitig reit ihren Bohrungs- und Mantelflächen ohne Spiel, gegebenenfalls unter gewisser Spannung all den Schulterflächen der inneren und äußeren Rollbahnringe anliegen. Es sind wohl Werkstoffe für Wälzlagerkäfige bekannt, die in der Lage sind, 01 aufzusaugen; wie z. B. Käfige aus Sintermetallen, Kunstharz, Schichtholz oder Papier. Kenner dieser Werkstoffe erreicht jedoch :die Saugfähigkeit von Filz.The invention described next is based on the intention of using the simplest means to create a roller bearing cage which on the one hand makes the bearing self-locking and on the other hand does the same to the outside. at the same time closes dust-tight. In order to achieve this purpose, according to the invention, a material is used for the cages which is capable of sucking up the oil which is necessary for lubrication. and: to release small quantities back onto the surfaces of the rolling elements and runways during operation. Around. To achieve a sufficient sealing effect of the cage by contacting the shell or bore surfaces of the cage against the rims or other surfaces next to the runways, the material must have a certain elasticity or compressibility. As material wllrd :. in order to achieve this goal, felt is provided. The concept of the invention is based on using an elastic, oil-absorbent material and designing the cages in such a way that, when enclosing the rolling elements, their bore and jacket surfaces rest without play, possibly under a certain tension, all of the shoulder surfaces of the inner and outer raceway rings . There are probably known materials for roller bearing cages that are able to absorb 01; such as B. cages made of sintered metals, synthetic resin, plywood or paper. However, those familiar with these materials will achieve: the absorbency of felt.
Käfige aus Sintermetall, Schichtholz; Kunstharz od.:.dgl: können auch .auf den .Borden eines -der Rollbahuringe geführt sein. Aber alle diese bekannten Werkstoffe besitzen gleichzeitig nicht die zweite wichtige Eigenschaft, nämlich eine genügend große Elastizität oder Zusammendruck 7barkeit, die sie befähigen würde, ohne Spiel, ja sogar unter geringer Spannung an den Schulterflächen der inneren und äußeren Rollbähuringe gleichzoiti.g anzuliegen, um das Lager nach außen sicher gegen Eindringen von Staub zu schützen.Cages made of sintered metal, plywood; Synthetic resin or the like: can also .be carried out on the .bords of one of the trolley rings. But all of these are known At the same time, materials do not have the second important property, namely sufficient elasticity or compressibility that would enable them to without play, even with little tension on the shoulder surfaces of the inner ones and outer roll-up rings to fit the same, in order to secure the bearing to the outside to protect against the ingress of dust.
So muß sowohl bei den Käfigen aus Sintermetall nach dem deutschen Patent 6947i2 als auch bei dem schweizerischen Patent 207 771 ein- geringes Spiel zwischen Borden und Käfigmantel bzw. Käfigsbohrungsflächen vorhanden sein. Schichtholz hat eine wesentlich geringere Elastizität als Filz. Auch die Saugfähigkeit von Schichtholz reicht bei weitem nicht an die von Filz heran. Filz nimmt etwa Zoo bis 300 Gewichtsprozent an Öl auf, Schichtholz dagegen kaum 111/9. In ,der schweizerischen Patentschrift wild dazu angegeben, daß eine gewisse Saugfähigkeit,des Holzes zurückbleibt, so daß die offenen Zellen etwas von dem Schmiermittel aufsaugen können. Die- offenen Zellen werden vom Bindemittel gefüllt.In the case of the cages made of sintered metal according to the German patent 6947i2 as well as the Swiss patent 207 771, there must be a slight play between the ribs and the cage jacket or the cage bore surfaces. Laminated wood is much less elastic than felt. The absorbency of plywood is nowhere near that of felt. Felt absorbs up to 300 percent by weight of oil , whereas plywood hardly absorbs 111/9. In, the Swiss patent wildly stated that a certain absorbency of the wood remains so that the open cells can soak up some of the lubricant. The open cells are filled with the binding agent.
Die entgegengehaltenen Käfige schließen das Lagerinnere nicht gegen Staub und Schmutz nach außen ab. Das amerikanische Patent 98o ioi sucht den Nachteil der geringeren Elastizität dadurch zu vermeiden, daß der Käfig mit besonderen federnden Dichtungselementen an .den Außenseiten versehen wird, die sich gegen die Borde .der Rollba!hnringe anlegen: Ein solcher Käfig besteht aber aus vielen Teilen und wird daher kompliziert und teuer. Käfige gemäß der neu angemeldeten Erfindung besteben Jägegen :aus einem einheitlichen ölaufsaugenden, elastischen Werkstoff und können aus einem Stück oder aus zwei miteinander verbundenen symmetrischen Teülen bestehen. Sie sind daher in ihrer Gestaltung einfach und billig.The counter-held cages do not close the interior of the bearing against dust and dirt from the outside . The American patent 98o ioi seeks to avoid the disadvantage of lower elasticity by providing the cage with special resilient sealing elements on the outer sides, which rest against the rims of the roller rings: Such a cage consists of many parts and therefore becomes complicated and expensive. Cages according to the newly registered invention are made of a single, elastic material that absorbs oil and can consist of one piece or two symmetrical parts connected to one another. They are therefore simple and inexpensive to design.
In der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt.The drawing shows two exemplary embodiments of the subject matter of the invention shown.
Abb. i zeigt ein Zylinderrollenlager, bestehend aus dem Außenring a, .dem Innenring b, den Rollen c und dem Käfig d.Fig. I shows a cylindrical roller bearing consisting of the outer ring a, .the inner ring b, the rollers c and the cage d.
Wie aus Abyb. 2 ersichtlich, sind in den Käfig d rechteckige Öffnungen e eingearbeitet, die- die Käfigtaschen bilden. Im Lager liegt der Käfig sowohl an den Borden .des Außenringes a als auch an Borden des Innenringes b an und schützt damit die Rollen c vor Verunreinigungen, die von außen in das Lager dringen könnten.Like from Abyb. 2, there are rectangular openings in the cage d e incorporated, which form the cage pockets. In the camp, the cage rests against both and protects the edges of the outer ring a as well as the edges of the inner ring b so that the rollers c from contamination that could penetrate the bearing from the outside.
In Abh. 3 wind ein Kugellager gezeigt, a1 ist der Außenring, bi der Innenring, cl die Kugeln und dl Ider Käfig.In dep. 3 a ball bearing is shown, a1 is the outer ring, bi the Inner ring, cl the balls and dl Ider cage.
Abb. 4. zeigt, wie .in den Käfig dl Löcher e1 als Käfigtaschen für .die Kugeln eingearbeitet sind. Der Käfig liegt sowohl auf den Schultern des Außenringes cal als auch auf denen des Innenringes b1 an, so dlie Kugeln vor Verunreinigungen, die von außen eindringen könnten, schützend.Fig. 4. shows how. In the cage dl holes e1 as cage pockets for .the balls are incorporated. The cage lies on both the shoulders of the outer ring cal as well as on those of the inner ring b1, so the balls from contamination, that could penetrate from the outside, protective.
