Abstract
Description
Schmierölumlauf für Selbslschmierungslager Die Erfindung betrifft einen Schmierölumlauf für Selbstschmierungslager mit einer Reibungspumpe, die aus einem Ölsumpf im Lagergehäuse-Unterteil fördert. Lubricating oil circulation for self-lubricating bearings The invention relates to a lubricating oil circuit for self-lubricating bearings with a friction pump that consists of promotes an oil sump in the lower part of the bearing housing.
In den meisten Fällen, in denen das Schmieröl zusätzlich die Aufgabe hat, Wärme abzuführen, reicht die Ölrückkühlung durch Wärmeabstrahlung an die umgebende Luft nicht aus, da 01 auch isolierende Eigenschaften hat. An einer Kühlfläche kühlen daher bei laminarer Strdmung nur die wandungsnahen Ölschichten ab, nehmen dadurch an Viskosität zu, haften dementsprechend stärker und hemmen als iselierende Schicht den Wärmeübergang. Kühlrohre und Wasserräume, die in einem Ölbehälter eingebaut sind, ermöglichen nur dann eine gute Rühlwirkung, wenn die Strömungsgeschwindigkeit des Öls genügend groß ist. Das Q1 muß deshalb im Zwangsumlauf an den Kühlfläciien vorbeigeführt werden.In most cases the lubricating oil also does the job has to dissipate heat, the oil recooling is sufficient by radiating heat to the surrounding area Do not let out air, as 01 also has insulating properties. Cool on a cooling surface Therefore, in the case of laminar flow, only the oil layers close to the wall decrease and thus decrease increase in viscosity, adhere accordingly more strongly and inhibit as an insulating layer the heat transfer. Cooling pipes and water spaces built into an oil tank allow a good cooling effect only if the flow velocity of the oil is sufficiently large. The Q1 must therefore be forced to circulate on the cooling surfaces be led by.
Aufgabe der Erfindung ist es, bei einem Zwangsumlauf des Öles auch eine gute Kühlung des Öles durchzuführen.The object of the invention is also when the oil is forced to circulate carry out a good cooling of the oil.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß das Lagergehäuse-Unterteil in eine Pumpenkammer, zwei Rücklaufkammern und eine Kühlkammer unterteilt ist und die einzelnen Kammern für einen Zwangsumlauf untereinander durch Öffnungen und Kanäle verbunden sind und daß das Gehäuse-Unterteil mit Kühlrippen versehen ist. Ein Verbindungskanal ist zwischen Kühlkammer und Pumpenkammer im mittleren Gehäuseunterteil angeordnet.This object is achieved according to the invention in that the bearing housing lower part is divided into a pump chamber, two return chambers and a cooling chamber and the individual chambers for forced circulation among each other through openings and channels are connected and that the lower housing part is provided with cooling fins. A connecting channel is arranged between the cooling chamber and the pump chamber in the middle lower part of the housing.
In den Zeichnungen ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Es zeigen: Fig. 1 einen Längsschnitt durch ein Axialgleitlager mit Radiallager, Fig. 2 einen Querschnitt nach Linie II-II der Fig. 1 und Fig. 3 einen Teilschnitt nach Linie III-III der Fig. 1 Eine Welle 1 trägt eine Druckscheibe 2 und ist über Kippsegmente 3 in einem aus dem Lagerunterteil 5 und dem Lageroberteil 6 bestehenden Lagergehäuse gelagert. Ein Radiallager 4 ist weiterhin vorhanden.In the drawings, the subject matter of the invention is in one embodiment shown. 1 shows a longitudinal section through an axial sliding bearing Radial bearing, FIG. 2 shows a cross section along line II-II of FIG. 1 and FIG. 3 shows a Partial section along line III-III in FIG. 1 A shaft 1 carries a thrust washer 2 and is via tilting segments 3 in one of the lower bearing part 5 and the upper bearing part 6 existing bearing housings. A radial bearing 4 is still present.
Zwischen dem Außenmantel 9 der Druckscheibe 2 und der Innenwand des Lagerunterteils 5 wird eine Reibungspumpe 9 gebildet, die das Schmieröl aus dem Ölsumpf im Lagerunterteil 5 mit dem Ölstand 7 über die Leitungen 10 und 12 in die Lagerteilfuge 14 zu dem Radiallager 4 und den Kippsegmenten 3 fördert. An der Leitung 12 sind Ölverteilerdüsen 13 vorhanden.Between the outer jacket 9 of the thrust washer 2 and the inner wall of the Bearing lower part 5, a friction pump 9 is formed, which the lubricating oil from the Oil sump in the lower bearing part 5 with the oil level 7 via the lines 10 and 12 into the Bearing part joint 14 to the radial bearing 4 and the tilting segments 3 promotes. On the line 12 there are oil distributor nozzles 13.
Der Ölbehälter im Lagerunterteil 5 ist in vier Kammern geteilt, die durch Öffnungen und Kanäle verbunden sind.The oil tank in the lower bearing part 5 is divided into four chambers, which are connected by openings and channels.
Das zurückfließende warme Öl gelangt in die beiden Rücklaufkammern 15 und 16 und dann durch zwei Öffnungen 11 am Grund der äußeren Wände in die Kilhlkammer 17. Durch einen Verbindungskanal 18 gelangt das gekühlte Öl dann in die Pumpenkammer 19, von wo es über die Reibungspumpe wieder zu den Gleitstellen gefördert wird. Das Gehäuse-Unterteil ist mit Kühlrippen 20 versehen.The returning warm oil reaches the two return chambers 15 and 16 and then through two openings 11 at the bottom of the outer walls into the kiln chamber 17. The cooled oil then passes through a connecting channel 18 into the pump chamber 19, from where it is conveyed back to the sliding points via the friction pump. The lower part of the housing is provided with cooling fins 20.
Durch die Verteilung der Kammern 15, 16, 17 und 19, die Öffnungen 11 und den Verbindungskanal 18 wird das Schmieröl im Zwangsumlauf an den gekühlten Flächen des Lagergehäuses vorbeigeführt, wobei die Reibungspumpe 8 für eine gute Ölförderung sorgt.By distributing the chambers 15, 16, 17 and 19, the openings 11 and the connecting channel 18, the lubricating oil is forced to circulate to the cooled Surfaces of the bearing housing passed, the friction pump 8 for good Oil production ensures.
