Description
Wälzlager. Vorliegende Erfindung bezieht sich auf ein Wälzlager, dessen Wälzkörper z. B. Kugeln oder Rollen sein können.
Gemäss der Erfindung sind mindestens zwei Kränze von Wälzkörpern, durch einen frei drehbar zwischen denselben angeordneten Ring voneinander getrennt, zwischen einem äussern und einem innern Laufring ange ordnet.
In der beiliegenden Zeichnung sind einige Ausführungsbeispiele von Wälzlagern gemäss der Erfindung dargestellt, und zwar zeigt: Fig. 1 das erste Ausführungsbeispiel' in einem Querschnitt durch die eine Hälfte, Fig. 2 eine Seitenansicht zu Fig. 1 und Fig. 3 bis 6 je ein weiteres Ausführungs beispiel im Querschnitt durch die eine Hälfte des Wälzlagers.
Bei dem in den Fig. 1 und 2 gezeichneten Beispiel eines Kugellagers ist zwischen zwei Kränzen von Kugeln 1 ein frei drehbarer Ring 2 angeordnet. Die beiden Kränze von Kugeln 1 laufen in diesem Ring 2 und einem innern bzw. äussern Laufring 3 bzw. 4.
Nach Fig. 3 ist der Ring 2' zwischen den zwei Kränzen von Kugeln 1 im Querschnitt 2- förmig. Der innere Laufring 3 sitzt auf einer Büchse 5 und kann durch Anziehen einer Mut ter 6 auf dieser Büchse festgeklemmt werden. Der Innenring 3 und die auf einer Welle 7 aufgepresste Büchse 5 besitzen leicht konischen Anzug. Auch hier sind die beiden Kränze von Kugeln zwischen dem innern Laufring 3 und dem äussern Laufring 4 angeordnet. Fig. 4 zeigt vier Kränze von Kugeln 1 mit dem frei drehbaren Ring 2 dazwischen und den beiden Laufringen 3 bzw. 4.
Es könnten auch mehr als vier Kränze von Kugeln 1 vor gesehen sein.
In Fig. 5 ist der frei drehbare Ring 2' wie in Fig. 3 von Z-förmigem Querschnitt. Das Wälzlager ist wie das in Fig. 3 gezeigte aus gebildet, mit dem Unterschied, dass die beiden Kugelkränze in. verschiedenen Ebenen ange ordnet sind.
Gemäss Fig. 6 sind an Stelle von Kugeln zwei Kränze von Rollen 8 vorgesehen, zwischen denen der frei drehbare Ring 9 angeordnet ist. Die Rollenkränze liegen zwischen den beiden Ringen 10 und 11.
Die gezeichneten und beschriebenen Wälz lager sind alles Radiallager. Das Wälzlager kann aber auch ein Axial- oder Drucklager sein, wobei zwischen zwei Kugel- oder Rollen kränzen ein Ring frei drehbar angeordnet ist, während sich die beiden Kränze zwischen zwei Laufringen befinden. Es könnten dabei zwei oder mehr Wälzkörperkränze vorgesehen sein.
Die beschriebenen Lager eignen sich ins besondere für hohe Drehzahlen, wobei die Wälz- körper der beiden Kränze mit verschiedener Drehzahl umlaufen, indem der frei drehbar zwischen denselben angeordnete Ring durch die sich darauf abwälzenden Kugeln oder' Rol len, in zur Welle entgegengesetzter Drehrich tung beeinflusst wird und dadurch mit redu zierter Drehzahl mitläuft. Wesentlich ist, dass die Wälzkörper ohne Spiel in den Ringen laufen.
Falls einer der Kränze durch einen Defekt eines oder mehrerer der Wälzkörper oder eines Laufringes blockiert wird, arbeitet der andere Kranz noch weiter, so dass die Ma schine, die mit dem Wälzlager versehen ist, noch weiterlaufen kann.
Roller bearing. The present invention relates to a rolling bearing, the rolling elements of which z. B. balls or rollers.
According to the invention, at least two rings of rolling elements, separated from one another by a ring freely rotatably arranged between them, are arranged between an outer and an inner race.
In the accompanying drawing, some exemplary embodiments of roller bearings according to the invention are shown, specifically showing: FIG. 1 the first exemplary embodiment in a cross section through one half, FIG. 2 a side view of FIG. 1 and FIGS. 3 to 6 each Another embodiment example in cross section through one half of the rolling bearing.
In the example of a ball bearing shown in FIGS. 1 and 2, a freely rotatable ring 2 is arranged between two rings of balls 1. The two rings of balls 1 run in this ring 2 and an inner and outer race 3 and 4, respectively.
According to FIG. 3, the ring 2 'between the two rings of balls 1 is 2-shaped in cross section. The inner race 3 sits on a sleeve 5 and can be clamped by tightening a courage ter 6 on this sleeve. The inner ring 3 and the sleeve 5 pressed onto a shaft 7 have a slightly conical shape. Here, too, the two rings of balls are arranged between the inner race 3 and the outer race 4. 4 shows four rings of balls 1 with the freely rotatable ring 2 in between and the two raceways 3 and 4, respectively.
There could also be more than four rings of balls 1 before.
In FIG. 5, the freely rotatable ring 2 ', as in FIG. 3, has a Z-shaped cross section. The roller bearing is formed like that shown in Fig. 3, with the difference that the two ball races are in. Different levels are arranged.
According to FIG. 6, two rings of rollers 8 are provided instead of balls, between which the freely rotatable ring 9 is arranged. The roller and cage assemblies lie between the two rings 10 and 11.
The drawn and described rolling bearings are all radial bearings. The roller bearing can also be an axial or thrust bearing, with a ring being freely rotatable between two ball or roller rings, while the two rings are located between two races. Two or more rolling element rings could be provided.
The bearings described are particularly suitable for high speeds, with the rolling elements of the two rims rotating at different speeds by influencing the freely rotatable ring between them in the direction of rotation opposite to the shaft through the balls or rollers rolling on it and thus runs at a reduced speed. It is essential that the rolling elements run in the rings without play.
If one of the rings is blocked by a defect in one or more of the rolling elements or a race, the other ring continues to work so that the machine that is provided with the roller bearing can continue to run.
