Description
Zur Regelung der Fettmenge in Wälztagern wurde bereits vorgeschlagen, auf der Fettaustrittsseite eine auf der Welle befestigte Scheibe anzuordnen. Diese Scheibe ist an den feststehenden Teil der Lagerung so weit herangeschoben, daß ein Spalt frei bleibt. Durch diesen wird während des Betriebes auf Grund der abschleudernden Wirkung der Scheibe das überflüssige Fett nach außen befördert. Auf diese Weise wird, eine Anhäufung des Fettes bei den Nach.-sehmierungen des Wälzlagers. vermieden: Die Anordnung hat jedoch den Nachteil, d@aß eine axiale Verschiebung -der Welle nicht möglich ist. Nach einer solchen würde nämlich der Spalt unrichtige Abmessungen besitzen bzw. gar ein Schleifen der Scheibe an dem feststehenden Lagerteil eintreten.To regulate the amount of grease in roller bearings, it has already been proposed that to arrange a disk attached to the shaft on the grease outlet side. These Disc is pushed so far towards the fixed part of the storage that a Gap remains free. This is due to the thrown-off during operation Effect of the disc transports the excess fat to the outside. In this way becomes, an accumulation of the fat in the Nach.-sehmierungen of the rolling bearing. avoided: However, the arrangement has the disadvantage that an axial displacement of the shaft not possible. After this, namely, the gap would be incorrect dimensions own or even occur a grinding of the disc on the fixed bearing part.
Diese Nachteile werden,gemäß der Erfindung dadurch vermieden, daß am Umfang der Scheilbe Öffnungen vorgesehen werden, durch d6:e .das überflüssige Fett abgeschleudert wirdi: Besonders vorteilhaft ist es, wenn die Scheibe mindestens auf der den Wälzkörpern zugewandten Seite die Form eines flachen Kegelmantels besitzt und! Öffnungen nahe dem Umfang trägt, außenhalb ,deren einkegelförmiger Kranz an der Scheibe befestigt ist. Gemäß der Erfindung wird demnach das überflüssige Fett nicht mehr durch veränderliche Spalte, sondern durch auch nach axialen Verschiebungen der Welle gleichbleibende Öffnungen a'bgeschleudert.These disadvantages are avoided according to the invention in that openings are provided on the circumference of the wedge, through d6: e. the superfluous Fat is thrown offi: It is particularly advantageous if the disc at least on the side facing the rolling elements has the shape of a flat conical shell and! Openings near the circumference bears, outside, their conical rim is attached to the disc. According to the invention, therefore, the excess fat becomes no longer due to variable gaps, but also due to axial displacements openings that remain the same are thrown off the shaft.
In den. Big. i und 2 der Zeichnung ist ein AusführurLgsbeispiel,der Erfindung,dlargestellt. Hier ist die Welle i mit dem Wälzlager 2 im Lagergehäuse 3 gelagert, das durch die Deckel ¢ und 5 verschlossen. ist. Bei Nachschmierungen wird Idas frische Fett durch die im Lagergehäuse vorgesehenei Bohrung 6 und dfe Aussparung 7 im Lagerdeckels in das Lager 2 !hineingedrückt. Durch den feststehenden Ring 8 wird das sofortige Austreten des Fettes in den im Lagergebäue vorgesehenen Sammelraum 9 verhindert, der mit einem Kasten 1o in Verbindung steht. Der Ring 8 wird, zweckmäßig durch den Lagerdeckel 4 an, den feststehenden Teil der Lagerang gedrückt und dadurch festgehalten. Durch den Ring 8 soll weÜerhin vermieden werden, daß durch Erwärmung dünnflüssig gewordenes Fett sofort durch die im Lagergehäuse vorgesehene Öffnung austritt. Durch die mit der Welle fest verbundene Scheibe r i wirdidas überflüssige Fett aus .dem Lager in: den Sammelraum 9 befördert. Hierauf wind das Fett im Kasten iö aufgefangen. Hierbei besitzt die Scheibe ii die Formeines flachen Kegelmantels und trägt nahe dem Umfang Öffnungen 12 (s. auch Fig.2), außerhalb deren ein kegelförmigeT Kranz 13 an der Scheibe befestigt isst. Bei Drehen der Scheibe gleitet offensichtlich das Fett an &r Kegelfläche entlang und wird durch die Schlitze 12 hinausgeschleudert. Die Anzahl und Größe der Schlitze kann: ohne weiteres vorn Fall zu Fall, z. B. durch Versuche, bestimmt werden.In the. Big. i and 2 of the drawing is an exemplary embodiment of the invention. Here the shaft i with the roller bearing 2 is mounted in the bearing housing 3, which is closed by the covers ¢ and 5. is. During relubrication, the fresh grease is pressed into the bearing 2! Through the bore 6 and recess 7 in the bearing cover provided in the bearing housing. The fixed ring 8 prevents the grease from immediately escaping into the collecting space 9 provided in the storage building, which is connected to a box 1o. The ring 8 is expediently pressed by the bearing cover 4 to the fixed part of the bearing and thereby held in place. The ring 8 is intended to prevent grease that has become thin as a result of heating immediately escaping through the opening provided in the bearing housing. The excess grease is conveyed from the bearing into the collecting chamber 9 by the disk r i firmly connected to the shaft. Then the fat is caught in the box. Here, the disc has the shape of a flat truncated ii shell and carries near the periphery of apertures 12 (s. Also Figure 2), outside of which a ring kegelförmigeT 1 3 attached to the disc eating. When the disk is rotated, the fat obviously slides along the conical surface and is thrown out through the slots 12. The number and size of the slots can: without further ado case by case, z. B. by experiments.
