Description

Die Erfindung bezieht sich auf eine Verbesserung des Segmentblocklagers für waagerecht liegende Wellen, insbesondere von Kreiselpumpen nach Patent 883983. The invention relates to an improvement of the segment block bearing for horizontally lying shafts, in particular centrifugal pumps according to patent 883983.

Bei derartigen Lagern hat sich herausgestellt, daß das zwischen den Segmentblöcken und dem Druckring herausgepreßte Schmieröl, das durch die Lagerreibung stark erwärmt worden ist und in den Ölsammelraum des Lagers zurückfließt, von den Schmierringen, insbesondere von dem benachbarten Schmierring, wieder aufgenommen wird, so daß die Welle an dieser Stelle mit bereits erhitztem Öl geschmiert wird.In such camps it has been found that between the Lubricating oil squeezed out of the segment blocks and the pressure ring, which is caused by the bearing friction has been heated strongly and flows back into the oil collecting chamber of the bearing from the Lubricating rings, in particular from the adjacent lubricating ring, added again so that the shaft is lubricated at this point with oil that has already been heated.

Zur Beseitigung dieses Übelstandes wird daher vorgeschlagen, zwischen dem Ölabfluß an den Stirnflächen der Segmentblöcke und dem benachbarten Schmierring ein in den Ölsammelfaum eintauchendes Trennblech vorzusehen. Hierdurch wird erreicht, daß das an den Segmentblöcken erwärmte Öl nicht sofort von dem benachbarten Schmierring wieder aufgenommen wird, sondern sich vor dem Schmierring sammelt, sich hier abkühlt und dann erst in angekühltem Zustand nach unten fließt, wo es unter dem Trennblech hindurchtretend weiter abgekühlt wird und erst dann von den Schmierringen wieder aufgenommen werden kann. Die Strömung im Ölsammelraum wird dadurch also verbessert und eine gute Kühlung des Öles herbeigeführt.To eliminate this drawback, it is therefore proposed between the oil drainage at the end faces of the segment blocks and the adjacent lubricating ring a separating plate immersed in the oil collecting chamber is to be provided. This achieves that the oil heated on the segment blocks is not immediately released from the adjacent lubricating ring is resumed, but collects in front of the lubricating ring, where it cools down and only then flows down when it has cooled down, where it flows under the partition plate passing through it is further cooled and only then again by the lubricating rings can be included. The flow in the oil collecting chamber is thus improved and brought about a good cooling of the oil.

In der Zeichnung ist die Erfindung in einem Längsschnitt beispielsweise dargestellt. Ebenso wie beim Gegenstand nach dem Patent 883 983 besitzt -das Lager zwei Schmierringe a mit Abstreifern b. Das Öl gelangt durch die Nuten c in den Raum, in dem sich die Segmentblöcke h befinden, gegen die sich der Druckring e legt, der von dem Flansch f der Lagerschale umfaßt wird. Durch den Spalt d gelangt das Öl in den unteren Ölraum des Lagers. Öffnungen i bzw. ein Rohrstutzen h dienen zur Zuführung von Öl. Zwischen den Segmentblöcken h und dem benachbarten Schmierring ist nun eine Trennwand L eingebaut, die in den Ölsammelraum hineinragt und deren Breite mindestens dem Durchmesser der Schmierringe entspricht. Hierdurch wird verhindert, daß das aus dem Segmentblocklager herausgepreßte heiße Öl unmittelbar von den Schmierringen wieder aufgenommen werden kann. Das heiße Öl sammelt sich vielmehr vor der Wand l und sinkt, sich allmählich abkühlend, nach unten, wo es unter der Wand hindurchtretend in abgekühltem Zustand zu den Schmierringen a wieder geangen kann.In the drawing, the invention is shown in a longitudinal section, for example. As with the object according to patent 883 983, the bearing has two lubricating rings a with wipers b. The oil passes through the grooves c into the space in which the segment blocks h are located, against which the pressure ring e, which is encompassed by the flange f of the bearing shell, rests. The oil reaches the lower oil chamber of the bearing through the gap d. Openings i or a pipe socket h are used to supply oil. A partition L is now installed between the segment blocks h and the adjacent lubricating ring, which protrudes into the oil collecting space and whose width corresponds at least to the diameter of the lubricating rings. This prevents the hot oil pressed out of the segment block bearing from being absorbed again directly by the lubricating rings. Rather, the hot oil collects in front of the wall 1 and sinks, gradually cooling down, where it passes under the wall and in a cooled state can reach the lubricating rings a again.
