Description

  

      Ölfangeinrichtung    für     Iturbelgetriebe.       Die vorliegende     Erfin?i@ng    bezieht sich  auf eine Fangeinrichtung     für        Kurbelgetriebe     insbesondere von     Brennkraftmasehinen    für  das aus den     Schubstangerlagern    tretende  Schmieröl.

   Sie besteht     d@i.rin,    dass am Kur  belzapfenlager der Schubstange beidseitig  Schleuderringe, und an den Innenseiten der  Kurbelarme sie umfassende Fangringe mit  mindestens einer     Ausflussstelle    am Orte gröss  ter Fliehkraft angebracht sind, aus welchen  das aufgefangene 01 in     feststnliende    Fang  einrichtungen im Kurbelraum     geschleudert     wird. Diese können als Kurbelverschalung  ausgebildet sein. Sie können im     Kurbelraum     äussere und innere zur     Kurbelwellenaxe     koaxiale Wände besitzen, zwischen welchen  das Ablauföl geleitet wird.  



  Das aus dem andern Zapfenlager der  Schubstange austretende 'Öl kann zum     Bei-          epiel    durch Bohrungen in der Schubstange  oder durch Leitungen längs derselben auch in  die Fangringe an den Kurbelarmen geleitet  werden.    Die Erfindung bezweckt, das aus den bei  den. Lagern der Schubstange austretende Öl  aufzufangen., um zu verhindern, dass .dieses  Öl im Kurbelgehäuse herumgespritzt wird  Und damit an die sich bewegenden Teile,  wie an die     Schubstange    und bei     doppeltwir-          kenden    Maschinen an den Kreuzkopf, bei  einfachwirkenden an den Kolben und die       Zylinderinnenflächen    gelangt.

   Kurbel- und       Kolbenzapfenlager    der Schubstange müssen  reichlich geschmiert werden wegen der ver  hältnismässig hohen Flächendrücke, so dass  eine ziemliche     Henge    Öl aus diesen Lagern  austritt. Gesellt sich nun bei     einfachwirken-          eien    Maschinen .diese Ölmenge zum Zylinder  schmieröl, so gelangt diese Schmieröl  mischung an die Wände des Zylinders und  zum Beispiel bei Kompressoren in die Ver  dichtungsräume     bezw.    bei     Brenükraftmaschi-          nen    in die Verbrennungsräume. Ferner  kann dieses Öl, das zum Teil fein zerstäubt  ist mit der Luft im Kurbelraum explosible  Dämpfe bilden.

   Durch die     Einrichtungen         gemäss der vorliegenden Erfindung werden  diese Nachteile vermieden, oder wenigstens  in sehr starkem Masse     vermindert.    Ferner  wird das Schmieröl, .das sonst durch Herum  spritzen oder Eindringen in die Zylinder  räume verloren gehen würde, gesammelt und       bann    wieder verwendet werden, wodurch der  Schmierölverbrauch ganz wesentlich ver  ringert wird.  



  In der beiliegenden Zeichnung ist ein  Ausführungsbeispiel der Erfindung gezeigt.       Abb.    1 zeigt einen Längsschnitt durch  das Kurbelzapfenlager der Schubstange mit  der Kurbel im innern     Totpunkt;        Abb.    2  zeigt eine Seitenansicht, und     Abb.    3 Details  in grösserem     Massstabe.     



  1 ist die Schubstange. Das aus ihrem  Kurbelzapfenlager austretende Öl     fliesst    un  ter dem Einfluss der     Zentrifugalwirkung    an  die Schleuderringe 2, welche es in die auf  den Kurbelwangen .sitzenden Fangringe 3       abschleudern.    An diesen Fangringen :3 sied  an Orten grösster Zentrifugalkraft Abläufe  4 angebracht, die das Öl in eine     Ölfangvor-          richtung    5 leiten. Diese Ölfangvorrichtungen  5 sind an der Grundplatte 6 befestigt und  leiten das Öl in den Ölsumpf 7 in der Grund  platte 6.

   Die     Ölfangvorrichtungen    5 sind  mit zur     Kurbelwellenaxe    koaxialen äussern  Wänden S und     innern    Wänden 9 versehen.  Die Ölabläufe 4 münden in den Zwischen  räumen<B>10,</B> so dass das eingeführte Öl nicht  in den Bereich der Kurbel gelangt. 11 sind  die Rohrleitungen, die das vom nicht gezeich  neten andern Zapfenlager der Schubstange  abfliessende Öl in Bohrung 12 im     kurbelsei-          tigen    Kopf der     Schubstange    1 leiten, von wo    es auf die     Olschleuderringe    2 fliesst, die das  aus der Bohrung 12     austretende    Öl abfangen  und mit dem Öl aus dem Kurbelzapfenlager  in die Fangringe 3 weiterleitet.



      Oil trap for Iturbel gear. The present invention relates to a catching device for crank mechanisms, in particular for internal combustion engines, for the lubricating oil emerging from the push rod bearings.

   It consists in the fact that sling rings are attached on both sides of the crank pin bearing of the push rod, and on the inside of the crank arms they have comprehensive catch rings with at least one outlet point at the location of the greatest centrifugal force, from which the caught oil is thrown into fixed catch devices in the crankcase becomes. These can be designed as a crank casing. In the crankcase, they can have outer and inner walls that are coaxial with the crankshaft axis, between which the drain oil is directed.



  The oil emerging from the other journal bearing of the push rod can, for example, be conducted through bores in the push rod or through lines along the same into the catch rings on the crank arms. The invention aims that from the at the. Storage of the pushrod to catch the oil escaping. To prevent this oil from splashing around in the crankcase and thus to the moving parts, such as the pushrod and, in the case of double-acting machines, to the crosshead, in the case of single-acting machines to the piston and the inner surfaces of the cylinder got.

   The crank and piston pin bearings of the push rod have to be lubricated abundantly because of the relatively high surface pressures, so that quite a bit of oil escapes from these bearings. If, in single-acting machines, this amount of oil is added to the cylinder lubricating oil, this lubricating oil mixture reaches the walls of the cylinder and, for example, in the case of compressors in the compression chambers. in the case of burners in the combustion chambers. This oil, which is partly finely atomized, can also form explosive vapors with the air in the crankcase.

   The devices according to the present invention avoid these disadvantages, or at least reduce them to a very great extent. Furthermore, the lubricating oil, which would otherwise be lost by splashing around or penetrating into the cylinder chambers, is collected and can be reused, which significantly reduces the consumption of lubricating oil.



  An exemplary embodiment of the invention is shown in the accompanying drawing. Fig. 1 shows a longitudinal section through the crank pin bearing of the push rod with the crank in the inner dead center; Fig. 2 shows a side view, and Fig. 3 shows details on a larger scale.



  1 is the push rod. The oil emerging from its crank pin bearing flows under the influence of the centrifugal effect to the slinger rings 2, which throw it into the catch rings 3 sitting on the crank webs. On these catch rings: 3, drains 4 are attached at places with the greatest centrifugal force, which guide the oil into an oil catch device 5. These oil collecting devices 5 are attached to the base plate 6 and direct the oil into the oil sump 7 in the base plate 6.

   The oil collecting devices 5 are provided with outer walls S and inner walls 9 which are coaxial with the crankshaft axis. The oil drains 4 open into the intermediate spaces <B> 10 </B> so that the introduced oil does not get into the area of the crank. 11 are the pipelines that guide the oil flowing off from the other journal bearing of the push rod, not shown, into bore 12 in the crank-side head of the push rod 1, from where it flows to the oil sling rings 2, which catch the oil emerging from the bore 12 and with it transfers the oil from the crank pin bearing into the catch rings 3.
