Description

Vollschaftkolben, insbesondere für Brennkraftmaschinen, Kompressoren u. dgl.Full shaft pistons, in particular for internal combustion engines, compressors and the like

Zusatz zur Patentanmeldung A22663XII/47f Die Erfindung stellt eine weitere Ausbildung der Vollschaftkolben, insbesondere für Brennkraftmaschinen. Kompressoren u. dgl.. nach Patentanmeldung A22663 YII/47f dar. Die Hauptpatentanmeldung bezieht sich auf solche Kalben, bei denen die auf den Seiten der Bolzenaugen liegenden Schaftflächen zurücktreten und die vom Kolbenkopf bis zum Schaftende durchlaufenden Begrenzungen zwischen den tragenden und den zurücktretenden Flächenteilen des Schaftes einen derart gekrümmten oder winkligen Verlauf haben, daß durch die zur Hubrichtung unterschiedlich geneigten Schrägen der Flächenbegrenzungen der Ölstau bzw. der Öldruck in den verschiedenen Höhenschnittebenen des Kolbens verschieden ist. Durch entsprechende Wahl der Schrägstellung der genannten Begrenzungen ist es möglich, das Öl den tragenden Schaftflächen eines Kolbens in dessen verschiedenen Höhenschnitten je nach den örtlichen Erfordernissen in entsprechendem Maße zuzuführen.Addendum to patent application A22663XII / 47f The invention represents a further training of the full shaft pistons, especially for internal combustion engines. Compressors and the like .. according to patent application A22663 YII / 47f refer to those calving in which the shaft surfaces lying on the sides of the bolt eyes step back and the boundaries running from the piston head to the end of the skirt between the supporting and the receding surface parts of the shaft have such a curved or angled course that by different to the stroke direction inclined slopes of the surface boundaries of the oil stagnation or the oil pressure in the various Elevation planes of the piston is different. By choosing the right angle the limitations mentioned, it is possible, the oil the supporting shaft surfaces of a Pistons in different height sections depending on the local requirements to be supplied in an appropriate amount.

Die Erfindung bezweckt, die angestrebte Regelung der Ölzufuhr zu den verschiedenen Teilen der tragenden Schaftflächen weiterzubilden, zu verbessern und erforderlichenfalls eine noch stärkere Erhöhung der Beölung an einzelnen tragenden Flächenteilen herbeizuführen. Dies wird erfindungsgemäß dadurch erreicht, dali die zurücktretenden Flächenteile des Schaftes abschnittsweise über angefaste oder gerundete Kanten in die tragenden Flächenteile des Schaftes übergehen, wobei die Anfasungen bzw. Abrundungen an denjenigen Stellen vorgesehen sind, an welchen eine besonders starke Ölzufuhr zu den tragenden Flächenteilen des Schaftes erwünscht ist. Durch solche Anfasungen wird der Ölübertritt von den zurücktretenden Flächenteilen zu den tragenden Flächen teilen des Schaftes erleichtert und entsprechend verstärkt.The invention aims to provide the desired control of the oil supply to the to further develop, improve and if necessary, an even greater increase in the oiling on individual load-bearing components To bring about surface parts. This is achieved according to the invention, the dali receding surface parts of the shaft in sections over chamfered or rounded ones Edges merge into the load-bearing surface parts of the shaft, the chamfers or roundings are provided at those points where a special strong oil supply to the supporting surface parts of the shaft is desired. By such chamfers will cause the oil to leak from the receding surface parts the supporting surfaces share of the shaft facilitated and reinforced accordingly.

Bei einer bevorzugten Ausführungsform der Erfindung sind die Anfasungen bzw. Abrundungen in verschiedenen Höhen der vom Kolbenschaft zum Schaftende laufenden Begrenzungen zwischen den zurücktretenden und den tragenden Flächenteilen verschieden ausgeführt und gegebenenfalls nur abschnittweise vorgesehen.In a preferred embodiment of the invention, the chamfers are or roundings at different heights running from the piston skirt to the skirt end Limitations between the receding and the load-bearing surface parts are different executed and, if necessary, only provided in sections.

In der Zeichnung sind Ausführungsbeispiele der Erfindung schematisch dargestellt.Exemplary embodiments of the invention are shown schematically in the drawing shown.

Fig. 1 und 2 stellen Vollschaftkolben in Seitenansicht dar.Fig. 1 and 2 show full skirt pistons in side view.

Bei dem Kalben nach Fig. 1 sind die tragenden Flächen des Schaftes mit 1 bezeichnet. Die den Bolzenaugen 2 benachbarten Schaftflächen 3 treten gegenüber den tragenden Schaftflächen 1 etwas zurück, woher die Begrenzungen 4 zwischen den tragenden Flächenteilen 1 und den zurücktretenden Flächenteilen 3 vom Kolbenkopf 5 bis zum unteren Schaftende durchlaufen. Bei den gezeigten Beispielen haben diese Begrenzungen einen winkligen Verlauf, sie können aber auch gekrümmt verlaufen.In the calving according to FIG. 1, the supporting surfaces are the upper denoted by 1. The shank surfaces 3 adjacent to the bolt eyes 2 face one another the supporting shaft surfaces 1 slightly back, where the boundaries 4 between the bearing surface parts 1 and the receding surface parts 3 from the piston head 5 to the lower end of the shaft. In the examples shown, they have Boundaries have an angled course, but they can also be curved.

An den Stellen 6 sind die Begrenzungen 4 angefast, so daß in diesen Abschnitten der Übertritt des Öls von den zurücktretenden Flächen 3 zu den betreffenden Stellen der tragenden Flächen 1 besonders begünstigt ist und der tragende Schaft in diesen Höhenquerschnitten besonders stark beölt wird.At the points 6, the boundaries 4 are chamfered so that in these Sections of the passage of the oil from the receding surfaces 3 to the relevant Place the supporting surfaces 1 is particularly favored and the supporting shaft is particularly heavily oiled in this height cross-section.
