Verfahren und Vorrichtung zum Herausnehmen des Kolbens bei einem Motor mit HohlkolbenMethod and device for removing the piston in an engine with a hollow piston
Die Erfindung bezieht sich auf.ein Verfahren und eine Vorrichtung zum Herausnehmen des Kolbens bei einem Motor mit Hohlkolben. Bei herkömmlichen Motoren wird zur Inspektion des Kolbens der Kolben aus dem Motor herausgenommen, indem der Zylinderkopfdeckel entfernt und der Kolben anschließend nach oben herausgezogen wird. Zum Entfernen des Zylinderkopfdeckels sind dabei Arbeiten wie das lösen der Zylinderkopfleitungen, der Ventilsteuerungen und der Zylinderkopfschrauben notwendig, die viel Aufwand.erfordern.The invention relates to a method and an apparatus For removing the piston in an engine with a hollow piston. In conventional engines, the piston is used to inspect the piston taken out of the engine by removing the cylinder head cover and then the plunger is pulled out upwards. To remove the cylinder head cover, work like this is involved loosen the cylinder head lines, the valve controls and the Cylinder head bolts are necessary, which require a lot of effort.
Der Erfindung liegt daher die Aufgabe zugrunde, die genannten herkömmlichen Nachteile zu beseitigen und ein Verfahren und eine Vorrichtung zu schaffen, die es gestatten, den Kolben mit einem Minimum an notwendigen Arbeiten aus dem Motor herauszunehmen.The invention is therefore based on the object of the aforementioned conventional To eliminate disadvantages and to provide a method and an apparatus which allow the piston with a minimum to remove necessary work from the engine.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das PleuelAccording to the invention, this object is achieved in that the connecting rod

von dem Kolben gelöst und im Kurbelgehäuse in eine geeignete Stellung gedreht wird, daß der Kolben aus dem Zylinder heraus und in das Kurbelgehäuse hinein gezogen wird und auf der Kurbelwelle abgesetzt wird, und daß anschließend die Kurbelwelle gedreht wirdj so daß der Kolben zu einer öffnung des Kurbelgehäuses bewlgt"wird, durch die hindurch der Kolben ohne Schwierigkeiten aus dem Motor ' herausgenommen werden kann.released from the piston and in a suitable position in the crankcase rotated so that the piston out of the cylinder and in the crankcase is pulled in and placed on the crankshaft, and then the crankshaft is rotated j so that the piston is moved to an opening in the crankcase ", through which the piston can be removed from the engine without difficulty ' can be removed.
Beispielsweise Ausführungsformen der Erfindung sind in der Zeichnung dargestellt. Es zeigt Exemplary embodiments of the invention are shown in the drawing. It shows

Fig. 10 einen Schnitt längs der Linie B-B in Fig. 8.FIG. 10 is a section along the line B-B in FIG. 8.
Die Erfindung wird im folgenden anhand der Fig. 1 beschrieben, nach der das Pleuel aus zwei Teilen 3a und 3b besteht, die bei 5 durch Schrauben 6 lösbar verbunden sind» Die Kurbelwelle7trägt ein an ihr befestigtes Gegengewicht 8, das mit einer Aussparung 9 versehen ist, in die der Kolben 2 hineingeschoben werden kann. The invention is described below with reference to FIG the connecting rod consists of two parts 3a and 3b, which at 5 through Screws 6 are detachably connected »The crankshaft 7 carries a counterweight 8 attached to it, which is provided with a recess 9 into which the piston 2 can be pushed.
Zum Herausnehmen des Kolbens aus dem Motor wird die Kurbelwelle gedreht, um den Kolben in seinen unteren Totpunkt zu bringen, wie es in Fig. 1 dargestellt ist. Anschließend v/erden die Schrauben 6 gelöst und der obere Teil 3a und der untere Teil 3b des Pleuels voneinander getrennt. Der untere Teil 3b des Pleuels wird im Kurbelgehäuse in eine geeignete Stellung gedreht, indem entweder die Kurbelwelle gedreht wird oder das Teil 3b um den Kurbelzapfen gedreht wird, ohne daß es dabei von der Kuroelwelle getrennt wird, wie es Figo 2 zeigt. Danach wird die Kurbelwelle wieder in den unteren Totpunkt gedreht, um das Gegengewicht 8 in eine Stellung unmittelbar unter den Kolben zu bringen, wobei das Pleuel in seiner Stellung bleibt, wie Fig. 3 zeigt. Anschließend wird der KoI-*The crankshaft is used to remove the piston from the engine rotated to bring the piston to its bottom dead center, like it is shown in FIG. Then the screws 6 are loosened and the upper part 3a and the lower part 3b of the connecting rod are earthed separated from each other. The lower part 3b of the connecting rod is rotated in the crankcase to a suitable position by either the The crankshaft is rotated or the part 3b is rotated around the crank pin without it being separated from the crankshaft, as Figo 2 shows. The crankshaft is then rotated back to bottom dead center to move the counterweight 8 into one position to bring directly under the piston, the connecting rod remaining in its position, as shown in FIG. 3. Then the KoI- *

ben 2 aus dem Zylinder nach unten herausgezogen und in die Aussparung 9 des Gegengewichts 8 hineingeschoben (Fig. 3)> und die Kurbelwelle wird mit dem in der Aussparung gehaltenen Kolben gedreht, um den Kolben in eine Stellung vor die für das Öl vorgesehene Öffnung zu bringen. Auf diese Weise kann der Kolben in Pfeilrichtung herausgenommen werden. Anstelle des oder zusätzlich zu dem Gegengewicht 8 kann an der Kurbelwelle ein geeignetes Teil zur Durchführung des oben beschriebenen Verfahrens angebracht sein.ben 2 pulled out of the cylinder downwards and into the recess 9 of the counterweight 8 is pushed in (Fig. 3)> and the crankshaft is rotated with the piston held in the recess, to bring the piston into a position in front of the opening provided for the oil. In this way the piston can in Direction of the arrow. Instead of or in addition to the counterweight 8, a suitable part can be used on the crankshaft be appropriate to carry out the procedure described above.
Der Einbau des Kolbens in den Motor geschieht in umgekehrter Reihenfolge der vorstehend "beschriebenen Schritte.The piston is installed in the engine in the reverse order of the steps described above.
Die Fig. 6 bis 10 zeigen eine andere Ausfiihrungs form der Erfindung, diesmal bei einem !Reihenmotor. Mit den vorhergenden Fig. übereinstimmende Teile sind mit den gleichen Bezugszeichen versehen. Das Herausnehmen und Einbauen des Kolbens geschieht in der gleichen Weise wie beim vorstehend beschriebenen Ausführungsbeispiel. FIGS. 6 to 10 show another embodiment of the invention, this time with an in-line engine. Parts that correspond to the previous figures are provided with the same reference numerals. The removal and installation of the piston is done in the same way as in the embodiment described above.
Wie aus dem Gesagten hervorgeht, kann ein in einem Motor eingebauter Kolben erfindungsgemäß mit minimalem Arbeitsaufwand ohne Entfernen des Zylinderkopfdeckeis herausgenommen werden, so daß die zur Inspektion und Wartung benötigte Zeit und Arbeit erheblich herabgesetzt wird.As can be seen from what has been said, a built-in in an engine Pistons according to the invention can be removed with minimal effort without removing the cylinder head cover, so that the time and labor required for inspection and maintenance is significantly reduced.
