Description
Kolbenstangenrollenführung für liegende Kolbenmaschinen Die Erfindung hat eine Rollenführung für liegende Kolbenmaschinen zum Gegenstande. Im Gegensatz zu der bekannten Verwendung einer fest gelagerten Rolle für die Lösung der Aufgabe kennzeichnet sich die Erfindung dadurch, daß eine lose, im Verhältnis zum Kolbenstangendurchmesser schmale Rolle, ohne Verwendung einer Zylinderstopfbüchse, in einen Schlitz des Abschlußgehäuses eingesetzt ist und auf gehärteten Bahnen läuft, die in die Kolbenstange und in die Laufbahn des Abschlußgehäuses eingelassen sind. Wohl ist die Führung von Maschinenteilen durch lose Rollen an sich nicht neu. Im vorliegenden Falle aber besteht eine neuartige fortschrittliche Wirkung besonders in der dampfdichten Einkapselung sowie dem Fortfall der Schmierung und der Stopfbüchse, wodurch verhütet wird, daß das Schmiermittel in den Zylinder gelangt und dort störend wirkt. Die schmale, lose Rolle veranlaßt dabei kein Stoßen und Ecken der Kolbenstange, wie angestellte Versuche gezeigt haben.Piston rod roller guide for horizontal piston machines The invention deals with a roller guide for horizontal piston machines. In contrast to the known use of a fixed role for the solution of the task The invention is characterized in that a loose, in relation to the piston rod diameter narrow roll, without using a cylinder gland, in a slot in the end housing is inserted and runs on hardened tracks that run into the piston rod and into the Career of the final casing are embedded. Probably the guidance of machine parts not new in itself through loose roles. In the present case, however, there is a new one progressive effect especially in the vapor-tight encapsulation as well as the elimination the lubrication and the stuffing box, which prevents the lubricant gets into the cylinder and has a disruptive effect there. The narrow, loose role caused no bumping and corners of the piston rod, as experiments have shown.
Auf der Zeichnung ist die Erfindung beispielsweise veranschaulicht; es sind Abb. r Längsschnitt durch die Kolbenstangenführung mit zugehörigem Zylinderteil, Abb.2 Ouerschnitt durch das Abschlußgehäuse.The invention is illustrated by way of example in the drawing; there are Fig.r longitudinal section through the piston rod guide with the associated cylinder part, Fig.2 Cross-section through the closure housing.
Für das Tragen der Kolbenstange a wird eine lose Rolle b benutzt, die zwischen zwei Stahlbahnen c, d läuft, von denen die obere d in die Kolbenstange, die untere c in die Führung e eingelassen ist. Rolle b und Bahnen c, d sind gehärtet und können ausgewechselt werden, ohne 'daß ein Nachdrehen der Kolbenstange erforderlich wird. Die Kolbenstange a läuft in dem Gehäuse f bei ihrem Hinundhergang auf der sich drehenden Rolle b. Die Laufbahn beträgt dabei die halbe Länge des Kolbenhubes; die Abrollgeschwindigkeit der Rolle ist nur halb so groß, was für die Erhaltung der Stahlbahnen von günstigem Einfluß ist. Jegliche Wartung und Schmierung fällt fort, da die Abnutzung auf ein sehr geringes Maß beschränkt wird. Die schmale Rolle wird mit geringem seitlichem Spiel eingelegt. Bei der unwesentlichen seitlichen Reibung der Rolle tritt eine nennenswerte Abnutzung nicht ein.To carry the piston rod a, a loose roller b is used, which runs between two steel tracks c, d , of which the upper d is embedded in the piston rod, the lower c in the guide e. Roll b and tracks c, d are hardened and can be exchanged without having to turn the piston rod. The piston rod a runs in the housing f as it reciprocates on the rotating roller b. The track is half the length of the piston stroke; the unwinding speed of the roll is only half as high, which is beneficial for maintaining the steel tracks. There is no need for any maintenance or lubrication, as wear is limited to a very low level. The narrow roll is inserted with little lateral play. With the insignificant lateral friction of the roller, there is no significant wear.
