Description
Gekühlte Kolbenstange Die Erfindung betrifft eine gekühlte Kolbenstange, insbesondere für doppeltwirkende Brennkraftmaschinen, nach dem Hauptpatent 585 551, bei der zwischen einem in der Kolbenstange angeordneten Kühlwasserrohr und der Kolbenstangenwand ein mit einer tropfbaren Flüssigkeit angefüllter Raum ausgespart ist.Cooled piston rod The invention relates to a cooled piston rod, especially for double-acting internal combustion engines, according to the main patent 585 551, between a cooling water pipe arranged in the piston rod and the piston rod wall a space filled with a drip liquid is left out.
Die Erfindung besteht darin, daß der mit der tropfbaren Flüssigkeit angefüllte Raum auch bei einem die Kolbenstange umgebenden Kühlwasserrohr vorgesehen ist. Durch diese Ausbildung wird bezweckt, die bereits beim Gegenstand des Hauptpatents erreichte Kühlwirkung des Kühlwassers auf die Kolbenstange noch weiter zu steigern.The invention consists in the fact that the liquid with the drip filled space is also provided in a cooling water pipe surrounding the piston rod is. The aim of this training is that which is already the subject of the main patent to increase the achieved cooling effect of the cooling water on the piston rod even further.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung im Schnitt dargestellt.An embodiment of the subject matter of the invention is shown in the drawing shown in section.
,a ist eine wassergekühlte Kolbenstange einer nicht weiter gezeichneten doppeltwirkenden Brennkraftmaschi.ne, bei der das in der Pfeilrichtung umlaufende Kühlwasser zwecks Vermeidung einer korrodierenden Wirkung auf die Stange durch Schutzrohre b und c von der Stangenoberfläche ferngehalten wird. Bist der ebenfalls wassergekühlte Kolben, @e der Kreuzkopf und f ein das ,äußere Schutzrohr umschließendes Laufrohr., a is a water-cooled piston rod of a not shown double-acting Brennkraftmaschi.ne, in which the rotating in the direction of the arrow Cooling water to avoid a corrosive effect on the rod through protective tubes b and c is kept away from the rod surface. Are the also water-cooled Piston, @e the crosshead and f a barrel surrounding the outer protective tube.
Schutzrohre und Laufrohr sind mittels an ihren oberen Enden angeordneter Flanschen ä, It und i festgelegt, während ihre unteren Enden durch Stopfbüchsen lt und L geführt sind, so daß: sie sich in der Längsrichtung frei ausdehnen können. Auf diese Weise werden die die Korrosion begünstigenden, ständig wechselnd auf die Kolbenstange ausgeübten Zug- und Druckkräfte von den Schutzrohren und dem Laufrohr ferngehalten und damit ihre Lebensdauer erheblich verlängert.Protective tubes and running tube are fixed by means of flanges ä, It and i arranged at their upper ends, while their lower ends are guided through stuffing boxes lt and L so that: they can expand freely in the longitudinal direction. In this way, the tensile and compressive forces that are constantly changing and exerted on the piston rod, which promote corrosion, are kept away from the protective tubes and the running tube and their service life is thus considerably extended.
Zwischen den Schutzrohren und dem Schaft der Kolbenstange sind mit einer nicht korrodierenden Flüssigkeit angefüllte Räumetn angeordnet, um sowohl eine Beeinträchtigung des Wärmeüberganges von der Kolbenstange auf die Schutzrohre wie auch eine Korrosionswirkung auf die Kolbenstange zu vermeiden.Between the protective tubes and the shaft of the piston rod are with a non-corrosive liquid-filled spaces arranged to both an impairment of the heat transfer from the piston rod to the protective tubes as well as to avoid a corrosive effect on the piston rod.
