Description
Schmierölkühlvorrichtung eines Außenbordmotors Die Erfindung bezieht sich auf eine Schmierölkühlvorrichtung eines Außenbordmotors mit Schmierölsumpf und Wasserkühlung des umlaufenden Schmieröles.Outboard Motor Lube Oil Cooling Apparatus The invention relates to on a lubricating oil cooling device of an outboard motor with a lubricating oil sump and water cooling of the circulating lubricating oil.
Bei bekannten Außenbordmotoren wird das Schmieröl unmittelbar durch das Fahrtwasser gekühlt, während es durch die Verbindungsleitungen zwischen dem Motor und dem Schmierölsumpf strömt. Bei einer derartigen Ausführung ist eine einwandfreie Kühlung des Schmieröles jedoch nur dann gewährleistet, wenn die genannten Verbindungsleitungen eine verhältnismäßig .große Außenfläche aufweisen, was jedoch im Hinblick auf die dadurch eintretende Erhöhung des Fahrtwiderstandes unerwünscht ist.In known outboard motors, the lubricating oil is immediately through the fairway is cooled while it flows through the connecting lines between the Motor and the lubricating oil sump flows. With such a design is a flawless one However, cooling of the lubricating oil is only guaranteed if the connecting lines mentioned have a relatively .large outer surface, but what is in view of the resulting increase in driving resistance is undesirable.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Schmierölkühlvorrichtung der eingangs genannten Art so auszubilden, daß sich bei einem sehr gedrängten räumlichen Aufbau eine besonders wirksame Kühlung ergibt.The invention is therefore based on the object of a lubricating oil cooling device of the type mentioned in such a way that in a very compact spatial Structure results in a particularly effective cooling.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Schmierölsumpf und ein gesonderter Schmierölkühler in einem zwischen dem Motor und dem Propeller vorgesehenen Zwischengehäuseteil nebeneinander derart angeordnet sind, daß der Kühlwasserraum des Schmierölkühlers und der Schmierölsumpf eine gemeinsame Zwischenwand besitzen, die in den Schmierölsumpf hineinragende Kühlrippen aufweist.This object is achieved according to the invention in that the lubricating oil sump and a separate lube oil cooler in one between the engine and the propeller provided intermediate housing part are arranged side by side in such a way that the cooling water space the lubricating oil cooler and the lubricating oil sump have a common partition, which has cooling fins protruding into the lubricating oil sump.
Für die erfindungsgemäße Ausführung ist somit wesentlich, daß mit Hilfe eines einzigen Kühlwasserraumes zugleich das im Ölraum des Schmierölkühlers befindliche Öl und das im Ölsumpf vorhandene Schmieröl gekühlt wird. Das Schmieröl kommt somit während eines Umlaufes zweimal in den Bereich der Kühlwirkung, was auch bei kleinen Abmessungen des Schmierölkühlers eine intensive Kühlung gewährleistet.For the embodiment according to the invention it is therefore essential that with With the help of a single cooling water space, that in the oil space of the lubricating oil cooler The oil in the oil sump and the lubricating oil in the oil sump is cooled. The lubricating oil thus comes into the range of the cooling effect twice during one cycle, which also With the small dimensions of the lubricating oil cooler, intensive cooling is guaranteed.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht. Es zeigt F i. g. 1 einen senkrechten Schnitt durch einen erfindungsgemäßen Außenbordmotor ohne den eigentlichen Antriebsmotor, F i g. 2 einen Schnitt längs der in F i g. 1 angedeuteten Schnittlinie A-A, F i g. 3 einen Schnitt längs der in F i g. 2 angedeuteten Schnittlinie B-B.An embodiment of the invention is illustrated in the drawing. It shows F i. G. 1 shows a vertical section through an outboard motor according to the invention without the actual drive motor, FIG. 2 shows a section along the line in FIG. 1 indicated section line A-A, F i g. 3 shows a section along the line in FIG. 2 indicated Section line B-B.
Der in den F i g. 1 bis 3 der Zeichnung dargestellte erfindungsgemäße Außenbordmotor hat einen Schmierölsumpf 1 und einen Schmierölkühler (Ölraum 3 und Kühlwasserraum 5), die dicht nebeneinander in einem Zwischengehäuseteil zwischen dem Antriebsmotor und dem Propeller angeordnet und durch eine Zwischenwand 29 (F i g. 2) voneinander getrennt sind. Der Kühlwasserraum 5 des Schmierölkühlers umgibt den zentralen Ölraum 3 (F i g. 2 und 3) und grenzt über die Zwischenwand 29 unmittelbar an den Ölsumpf 1 an. Auf einer Antriebswelle 27 (F i g. 1) sind eine Kühlwasserpumpe 11 sowie eine Schmierölpumpe 7 koaxial befestigt. Die Kühlwasserpumpe 11 saugt Kühlwasser durch ein Filtersieb 25 in einer Kühlwassereinlaßöffnung hinter dem Propeller an und drückt es durch eine an die Drucköffnung der Pumpe 11 angeschlossene Kühlwasserleitung 13 in den Kühlwasserraum 5 des Ölkühlers, um das durch den zentralen Ölraum 3 des Schmierölkühlers strömende Schmieröl zu kühlen. Das Kühlwasser kühlt jedoch zugleich auch das in dem Ölsumpf 1 befindliche Öl durch Wärmeaustausch über die Zwischenwand 29. Eine Reihe senkrecht sich erstreckender Kühlrippen 19 (F i g. 2 und 3) ragt, wie in F i g. 3 dargestellt, von der Zwischenwand 29 nach innen in den Ölsumpf 1 hinein, um so die Kühlwirkung des Kühlwassers noch zu verstärken. Vom Ölkühler wird das Kühlwasser nach oben zum Antriebsmotor geführt, um diesen zu kühlen. Der größere Teil des Kühlwassers wird aus einer Wasserabflußöffnung 21 am hinteren Teil des Außenbordmotors (F i g. 1) abgelassen, während der restliche, kleinere Teil des Kühlwassers zusammen mit den Verbrennungsgasen des Motors aus einer im unteren Bereich vorgesehenen Auspufföffnung 23 abgelassen wird.The in the F i g. 1 to 3 of the drawing, the outboard motor according to the invention has a lubricating oil sump 1 and a lubricating oil cooler (oil chamber 3 and cooling water chamber 5), which are arranged close to one another in an intermediate housing part between the drive motor and the propeller and separated from one another by a partition 29 (FIG. 2) are. The cooling water space 5 of the lubricating oil cooler surrounds the central oil space 3 (FIGS. 2 and 3) and is directly adjacent to the oil sump 1 via the partition 29. A cooling water pump 11 and a lubricating oil pump 7 are fastened coaxially on a drive shaft 27 (FIG. 1). The cooling water pump 11 sucks in cooling water through a filter screen 25 in a cooling water inlet opening behind the propeller and presses it through a cooling water line 13 connected to the pressure opening of the pump 11 into the cooling water space 5 of the oil cooler in order to cool the lubricating oil flowing through the central oil space 3 of the lubricating oil cooler . At the same time, however, the cooling water also cools the oil in the oil sump 1 by exchanging heat via the partition 29. A row of vertically extending cooling ribs 19 (FIGS. 2 and 3) protrudes, as in FIG. 3, from the partition 29 inwards into the oil sump 1, in order to further enhance the cooling effect of the cooling water. The cooling water is fed upwards from the oil cooler to the drive motor in order to cool it. The greater part of the cooling water is drained from a water drainage opening 21 at the rear of the outboard motor (Fig. 1), while the remaining, smaller part of the cooling water is drained together with the combustion gases of the engine from an exhaust opening 23 provided in the lower area.
Das Schmieröl wird durch einen Ölfilter 9 (F i g. 1) am unteren Teil des Ölsumpfes 1 gereinigt und von der unter dem Ölsumpf 1 angeordneten Schmierölumlaufpumpe 7 angesaugt.The lubricating oil is cleaned by an oil filter 9 (FIG. 1) on the lower part of the oil sump 1 and sucked in by the lubricating oil circulation pump 7 arranged below the oil sump 1.
Aus F i g. 2 ist zu ersehen, wie das aus der Schmierölpumpe 7 austretende Öl durch eine Ölleitung 15 in den zentralen Ölraum 3 des Schmierölkühlers geleitet wird und von dort durch eine Ölleitung 17 dem Motor zugeführt wird. Das Schmieröl strömt dann durch eine Leitung 31 wieder zum Ölsumpf 1 zurück, wobei es unter einem bestimmten Winkel auf die Zwischenwand 29 auftrifft. Diese Art der Ölrückführung in den Ölsumpf 1 führt zu einer erhöhten Wärmeübergangszahl zwischen dem Schmieröl und der Zwischenwand 29 und dadurch zu einer verbesserten Kühlwirkung. Schließlich enthält der Außenbordmotor in bekannter Weise eine Öleinfüllöffnung 33, eine ölpegelkontrollstange 35 und einen Ablaßstopfen 37 am Ölsumpf 1.From Fig. 2 it can be seen how the oil exiting the lubricating oil pump 7 is passed through an oil line 15 into the central oil chamber 3 of the lubricating oil cooler and from there is fed through an oil line 17 to the engine. The lubricating oil then flows back through a line 31 to the oil sump 1, where it strikes the partition 29 at a certain angle. This type of oil return into the oil sump 1 leads to an increased heat transfer coefficient between the lubricating oil and the partition 29 and thereby to an improved cooling effect. Finally, in a known manner, the outboard motor contains an oil filler opening 33, an oil level control rod 35 and a drain plug 37 on the oil sump 1.
