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.
