Description
Wälzlager Für die Lagerung von Wellen sind vielfach Wälzlager erforderlich, deren Laufringe Taumelbewegungen auszuführen vermögen. Soll ein solches auf eine Welle aufgezogenes Lager in die ihm als Träger dienende Bohrung eingeführt werden, dann muß der Außenring genau ausgerichtet sein. Weist dieser Ring auch nur eine geringe Neigung gegenüber der Wellenachse auf, dann treten beim Einführen in die Bohrung Verklemmungen auf, die es unmöglich machen, das Lager in seine Endlage zu bringen.Rolling bearings Rolling bearings are often required to support shafts, whose races are able to perform wobbling movements. Should such a Shaft mounted bearing are inserted into the bore serving as a carrier, then the outer ring must be precisely aligned. Does this ring only have one slight inclination with respect to the shaft axis, then occur when inserting into the Bore jams that make it impossible to move the bearing to its end position bring.
Dieses Ausrichten kann erst dann vorgenommen werden, wenn der Außenring am Rande der Bohrung anliegt, weil ein zuvor ausgerichteter Ring sich bei einer Berührung mit dem Rand der Bohrung wieder schief stellen würde.This alignment can only be done when the outer ring rests on the edge of the hole because a previously aligned ring is at a Would make contact with the edge of the hole crooked again.
Häufig ist aber das Lager wegen vorspringender Gehäuseteile oder aus anderen Gründen nicht mehr zugänglich, wenn es sich in der Lage, in der der Außenring ausgerichtet werden muß, befindet. In solchen Fällen läßt sich das Lager nur dann einbringen, wenn man zuvor seine Achse genau mit der Bohrungsachse in Übereinstimmung gebracht hat. Dies gelingt aber nur sehr selten, und daher ist das Einbringen des Lagers in den vorgenannten Fällen sehr mühevoll und zeitraubend.Often, however, the camp is due to protruding housing parts or from no longer accessible for other reasons when it is able to accommodate the outer ring must be aligned is located. In such cases, the camp can only be bring in, if one has previously his axis exactly in accordance with the axis of the hole brought. However, this only works very rarely, and therefore the introduction of the Storage in the aforementioned cases is very laborious and time-consuming.
Diesen Mangel vermeidet die Erfindung durch eine Maßnahme, die dazu führt, daß sich der Außenring des Lagers bei einer Berührung mit der Kante der das Lager aufnehmenden Bohrung von selbst ausrichtet. Zu diesem Zweck schlägt die Erfindung vor, in der Außenfläche dieses Ringes nahe der Stirnseite, mit der er in die Bohrung eingeführt wird, eine Ringnut vorzusehen. Diese erhält eine solche Querschnittsfläche, daß deren Begrenzung in dem der Ringmittelebene zugekehrten Bereich zur Zylinderachse zumindest annähernd senkrecht verläuft. Die der Ringmittelebene abgekehrte Kante der Nut wird zweckmäßig verrundet oder so ausgebildet, daß sie einen stumpfen Winkel bildet.The invention avoids this deficiency by a measure that does so leads to the fact that the outer ring of the bearing in contact with the edge of the Aligns bearing receiving bore by itself. To this end, the invention proposes before, in the outer surface of this ring near the face with which it is in the bore is introduced to provide an annular groove. This receives such a cross-sectional area, that their limitation in the area facing the ring center plane to the cylinder axis runs at least approximately vertically. The edge facing away from the central plane of the ring the groove is suitably rounded or formed so that it forms an obtuse angle forms.
Die Wirkungsweise dieser Nut sei an Hand der Zeichnung erläutert.The mode of action of this groove is explained with reference to the drawing.
Mit 1 ist der Wellenstumpf bezeichnet, auf dem der Innenring 2 des Wälzlagers aufgezogen ist. Der Außenring 3 soll in die Bohrung 4 eingeführt werden. Bewegt man zu diesem Zweck die Welle in Pfeilrichtung, dann dringt der geneigte Ring 3 mit seinem nach vorn stehenden Teil in die Bohrung ein, bis die Kante 5ª, der Nut 5 an die Kante 4ª der Bohrung 4 anstößt. Beim weiteren Verschieben der Welle in Pfeilrichtung wird der Ring verschwenkt und vermag, sobald er seine Mittellage erreicht hat, in die Bohrung einzudringen.1 with the stub shaft is referred to on which the inner ring 2 of the Rolling bearing is mounted. The outer ring 3 is to be inserted into the bore 4. If you move the shaft in the direction of the arrow for this purpose, the inclined shaft penetrates Ring 3 with its forward-facing part into the hole until the edge 5ª, the groove 5 abuts the edge 4ª of the bore 4. When moving the shaft further The ring is pivoted in the direction of the arrow and is able to do so as soon as it reaches its central position has managed to enter the hole.
