Description
<Desc/Clms Page number 1>
Kugellager.
Die Erfindung betrifft ein Kugellager, das ein geringes seitliches Spiel der Welle ermöglicht, wie es im Betriebe von Elektromotoren oder bei Wellen, die infolge Temperaturschwankungen axiale Längen- änderungen erfahren, wünschenswert ist.
Das in den beiden Figuren der Zeichnung dargestellte Kuggellager besteht im wesentlichen aus einem inneren auf der Welle sitzendem Kugellager gewöhnlicher Art und einem äusseren ebenfalls auf Kugeln gelagerten Teil, der jedoch nur eine axiale Bewegung zulässt und in dem das innere Kugellager sphärisch gelagert ist. Dieses äussere Lager besteht aus einem im Lagergehäuse mittels zweier Kronenschraubringe 4 und 5 in axialer Richtung einstellbaren äusseren Stahlring 1 und einem etwas kürzer gehaltenen inneren Stahlring 2, in dem das innere Kugellager sphärisch gelagert ist.
Zwischen beiden Ringen 1 und 2, die am inneren bzw. äusseren Umfange eine Anzahl axial verlaufender Kugelbahnnuten aufweisen, liegen durch einen zylindrischen Kugelkäfig geführt, Stahlkugeln, die eine geringe axiale Bewegung des Ringes 2 und somit auch der Welle gegenüber dem äusseren Ringe 1 ermöglichen. Die Grösse dieses Spieles ist durch den axialen Längenunterschied der Ringe 1 und 2 gegeben und durch Vorsprünge an den Kronenschraubringen begrenzt.
Um nach Einstellung des Lagers durch Verstellen und Festziehen der beiden Kronenschraubringe letztere in ihrer Stellung zu sichern, ist ein in die Ausnehmungen derselben eingreifender Bügel 6 vorgesehen, der durch eine kleine Stiftschraube am Gehäuse befestigt wird.
PATENT-ANSPRÜCHE :
1. Kugellager, dadurch gekennzeichnet, dass dessen Aussenlaufring den geringes Spiel aufweisenden
EMI1.1
senkrechten Ebenen liegen, so dass die Welle geringfügige Längsverschiebungen ausführen kann.

Ball-bearing.
The invention relates to a ball bearing which enables a small lateral play of the shaft, as is desirable in the operation of electric motors or in shafts that experience axial changes in length as a result of temperature fluctuations.
The ball bearing shown in the two figures of the drawing consists essentially of an inner ball bearing of the usual type seated on the shaft and an outer part also mounted on balls, which however only allows axial movement and in which the inner ball bearing is spherically mounted. This outer bearing consists of an outer steel ring 1 adjustable in the axial direction in the bearing housing by means of two crown screw rings 4 and 5 and a somewhat shorter inner steel ring 2 in which the inner ball bearing is mounted spherically.
Between the two rings 1 and 2, which have a number of axially running ball track grooves on the inner and outer circumference, are guided by a cylindrical ball cage, steel balls that allow a slight axial movement of the ring 2 and thus also of the shaft relative to the outer ring 1. The size of this game is given by the axial difference in length between rings 1 and 2 and limited by projections on the crown screw rings.
In order to secure the latter in its position after setting the bearing by adjusting and tightening the two crown screw rings, a bracket 6 engaging in the recesses of the same is provided, which is attached to the housing by a small stud screw.
PATENT CLAIMS:
1. Ball bearing, characterized in that its outer race has the little play
EMI1.1
perpendicular planes so that the shaft can perform slight longitudinal displacements.
