Description

Die Anordnung der Labyrinthdichtung eines. Wälzlagers bezweckt; eine leiehte Montage und Demontage insbesondere bei elektrischenMaschnen ' vornehmen zu können, ohne daß es nötig ist, die Dichtung von der Welle abgu2;ehen,.;l)e's geschieht erfindungsgemäß in der Weise, daß der fest stehende Labyrinthdichtungsteil den gleichen Außendurchmesser wie das Wälzlager besitzt, während der unilaufende Teil fest auf der Welle angebracht ist, und zwar derart, daß diese Teile beim Abziehen des Lagerschilds auf der Welle verbleiben. Sie bilden so einen ergänzenden Bestandteil des Wälzlagers.The arrangement of the labyrinth seal of a. Rolling bearing purposes; one Carry out easy assembly and disassembly, especially in the case of electrical machines to be able to remove the seal from the shaft without it being necessary to remove the seal from the shaft happens according to the invention in such a way that the fixed labyrinth seal part has the same outer diameter as the rolling bearing, while the non-running one Part is firmly attached to the shaft, in such a way that these parts when pulled off of the end shield remain on the shaft. They form a complementary component of the rolling bearing.

In der Zeichnung ist ein Ausführungsbeispiel der' Erfindung im Schnitt veranschaulicht. Das Wälzlager i ist auf der Welle 2 aufgepreßt.; Auf der: tinen Seite ist die gewöhnliche Filzabdichtung 3 an= geordnet, während sich auf der andern Seite eine kombinierte Filz- und Labyrinthdichtung befindet. die umlaufende Labyrinthhälfle 4,ist wie, das Wälzlager i auf die Welle 2 aufgepreßt. Die feststehende hälfte 5 ist im Wälzlagersitz eingeschoben und wird durch den Flansclbring 6, der zur Bildung des Labyrinths beiträgt, zusammen mit dem Fettkammerdeckel 7 durch die Schrauben 8 im Lagerschild 9 befestigt.In the drawing, an embodiment of the 'invention is in section illustrated. The roller bearing i is pressed onto the shaft 2 .; On the: tinen The usual felt seal 3 is arranged on one side, while on the other Side a combined felt and labyrinth seal is located. the surrounding half of the labyrinth 4, is like, the roller bearing i is pressed onto the shaft 2. The fixed half 5 is inserted in the roller bearing seat and is through the flange 6, which is used to form contributes to the labyrinth, together with the grease chamber cover 7 through the screws 8 fastened in the end shield 9.

Soll der Lagerschild 9 abgenommen werden, so wird er nach Lösen der Schrauben 8 in bekannter If the bearing plate 9 is to be removed, it becomes known after loosening the screws 8
