Description
<Desc/Clms Page number 1>
Kugellager mit einstellbarem Aussenlaufring.
Bei den bisher bekannten Kugellagern mit einschraubbarem Deckel macht die Einstellung grosse Schwierigkeiten, da bei zu geringem Anziehen das Lager schlottert, bei starkem Anziehen aber ein Klemmen zwischen Laufring und Gehäusedeckel auftritt, was immer zu unliebsamen Störungen Anlass geben kann. Gemäss der Erfindung wird dieser Übelstand dadurch beseitigt, dass der Gehäusedeckel federnd bzw. elastisch mit dem Gehäuse verbunden ist, so dass er bei, durch irgend welche Umstände hervorgerufenem einseitigem Druck, in der entsprechenden Richtung innerhalb bestimmter Grenzen nachgeben kann, ohne dass hierbei die Fühlung mit dem äusseren Laufring verloren geht.
In der Zeichnung sind zwei beispielsweise Ausführungsformen von Kugellagern gemäss der Erfindung im Schnitt veranschaulicht, und zwar zeigt Fig. 1 ein Kugellager mit einseitigem und Fig. 2 ein solches mit beiderseitigem Deckelabschluss. Das Kugellager besteht im wesentlichen aus dem Gehäuse 1, dem äusseren und inneren zylindrischen Laufring 2 bzw. 3 und dem Deckel 4. Der Innenumfang des Gehäuses 1 bzw. des Deckels 4 ist in bekannter Weise der gewölbten Form des äusseren Laufringes entsprechend ausgebildet. Die Festlegung des Deckels 4 am Gehäuse 1 erfolgt durch abgesetzte Schrauben 5. Zwischen dem Schraubenkopf und der Deckelwand sind Sprengringe 6 eingeschaltet, welche dem Anziehen des Deckels 4 einen gewissen Widerstand entgegensetzen und eine nachgiebige Lagerung desselben an dem Gehäuse bewirken.
Diese Art der Deckellagerung bezweckt ein Verklemmen wirksam zu verhindern, da bei einem etwa einseitig auftretenden, die Feder-
EMI1.1
kann, wodurch eine Entlastung erfolgt, und der ungestörte Betrieb des Lagers gewährleistet ist. Bei Abnutzung der Innenfläche des Deckels kann ohne weiteres durch Anziehen der Schrauben 5, ein Nachspannen bewerkstellig werden.
Bei der in Fig. 2 veranschaulichten Ausführungsform des Kugellagers mit beiderseitigem Deckelabschluss, stehen beide Deckel 4, 4'unter der Wirkung von Federn 6,6', wodurch die Elastizität des Lagers erhöht wird. Die Befestigung der Deckel 4 und 4'erfolgt durch gemeinsame Mutterschrauben 7, welche durch einen Ringflansch 9 der zylindrischen Innenwandung des Gehäuses 1 hindurchgreifen. 8 sind Dichtungsringe, welche ein Eindringen von Staub o. dgl. in das Kugellager verhindern.
Es ist selbstverständlich, dass anstatt der Sprengringe 6, beliebige andere Federn oder aber geeignete elastische Zwischenlagen (Gummipuffer o. dgl. ) zur Anwendung gelangen können, welche die nachgiebige Lagerung des bzw. der Deckel bilden.

Ball bearing with adjustable outer race.
In the previously known ball bearings with screw-in cover, the setting causes great difficulties, since if the bearing is not tightened enough, the bearing shakes, but if it is tightened too much, it jams between the race and the housing cover, which can always lead to unpleasant faults. According to the invention, this deficiency is eliminated in that the housing cover is resiliently or elastically connected to the housing, so that it can yield in the corresponding direction within certain limits in the event of one-sided pressure caused by any circumstances without touching it is lost with the outer race.
In the drawing, two exemplary embodiments of ball bearings according to the invention are illustrated in section, namely FIG. 1 shows a ball bearing with a one-sided cover and FIG. 2 shows one with a cover closure on both sides. The ball bearing consists essentially of the housing 1, the outer and inner cylindrical race 2 or 3 and the cover 4. The inner circumference of the housing 1 or the cover 4 is designed in a known manner to match the curved shape of the outer race. The cover 4 is fixed to the housing 1 by means of offset screws 5. Snap rings 6 are switched on between the screw head and the cover wall, which offer a certain resistance to the tightening of the cover 4 and cause it to be resiliently supported on the housing.
The purpose of this type of cover mounting is to effectively prevent jamming, as in the event of a one-sided occurrence, the spring
EMI1.1
can, whereby a relief takes place, and the undisturbed operation of the warehouse is guaranteed. If the inner surface of the cover wears out, tightening the screws 5 can easily be re-tensioned.
In the embodiment of the ball bearing illustrated in FIG. 2 with a cover closure on both sides, both covers 4, 4 'are under the action of springs 6, 6', whereby the elasticity of the bearing is increased. The covers 4 and 4 ′ are fastened by common nut screws 7 which reach through an annular flange 9 of the cylindrical inner wall of the housing 1. 8 are sealing rings which prevent dust or the like from entering the ball bearing.
It goes without saying that instead of the snap rings 6, any other springs or suitable elastic intermediate layers (rubber buffers or the like) can be used, which form the resilient mounting of the cover or covers.
