Description

Im allgemeinen wird der Kolben bei stehenden Maschinen nach oben ausgebaut. Hierzu ist nötig, daß die Ventile, die Antriebshebel mit den zugehörigen Wellen, die Auspufflei-"5 tung und der Luftansaugestutzen bzw. die "Spülleitung, ein Teil der Kühlwasserleitung, der Anlaßleitung und bei Dieselmotoren der Brennstoff- und Einblaseleitung und der Zylinderdeckel entfernt wird. Ferner muß dasIn general, the piston is removed upwards when the machine is at a standstill. For this it is necessary that the valves, the drive levers with the associated shafts, the exhaust pipe- "5 device and the air intake nozzle or the "flushing line, part of the cooling water line, the starter line and, in the case of diesel engines, the fuel and injection line and the cylinder cover Will get removed. Furthermore, it must

ίο Kühlwasser aus dem Zylinderdeckel, der Auspuffleitung und den gekühlten Ventilen abgelassen werden, bevor mit der Entfernung dieser Teile und dem eigentlichen Kolbenausbau begonnen werden kann.ίο Cooling water from the cylinder cover, the exhaust line and deflate the cooled valves before removing these parts and actually removing the piston can be started.

Es ist bekannt, daß der Kolben auch nach unten ausgebaut werden kann. Hierzu werden jedoch besondere Hebezeuge vorgesehen oder es müssen Teile der Zylinderbüchse entfernt werden.It is known that the piston can also be removed downwards. To do this will be however, special lifting gear is provided or parts of the cylinder liner have to be removed will.

Bei der in den Fig. 1 und 2 dargestellten Art des Kolbenausbaus ist dies nichf"nötig. Die Kolbenstange ist zweiteilig ausgeführt. Ungefähr im unteren Totpunkt wird die Verbindung des Kolbens α mit dem Stangenteil b und ebenso die des Stangenteils b mit dem Teil c gelöst, und der Kolben wird mit einer Stütze d abgefangen. Hierauf wird der Kolbenstangenteil δ entfernt (s. Fig. 1). Dann wird durch Drehen des Triebwerks (mittels Drehmaschine oder von Hand) der Kolbenstangenteil c nach oben bewegt, bis er gegen den Kolben α zu liegen kommt. Die Flanschen, die die Teile α und b verbinden, sind gleich denen, welche die Teile b und c verbinden, so daß die Stange c mit dem Kolben a verschraubt und durch Drehen am Triebwerk der Kolben herabgelassen werden kann, derart, daß er in die in Fig. 2 gezeichnete Stellung kommt. Hier setzt er sich auf einen Rahmen auf, auf dem er nach der Seite herausgezogen werden kann. In umgekehrter Weise erfolgt der Wiedereinbau des Kolbens. Es ist in den Figuren angenommen, daß der Raum für das Triebwerk, wie dies bei großen Schiffsdieselmotoren vielfach üblich ist, durch eine Zwischenwand von dem Zylinder getrennt ist.This is not necessary for the type of piston dismantling shown in FIGS. 1 and 2. The piston rod is made in two parts. Approximately at bottom dead center, the connection of the piston α to the rod part b and also that of the rod part b to the part c is released and the piston is caught with a support d. Then the piston rod part is δ removed (s. Fig. 1). Then, the engine is (by means of rotary machine or by hand) of the piston rod part c by moving up by turning until it against the piston α comes to rest. the flanges α the parts and b connected are the same as those which b the parts and c connect, so that the rod c screwed with the piston a and can be lowered by turning on the engine, the piston, in such a way that it comes into the position shown in Fig. 2. Here it sits on a frame on which it can be pulled out to the side It is assumed that the space for the engine, as is often the case with large marine diesel engines, is separated from the cylinder by a partition.
