Description
Zur Ausrüstung von Kurbelwellen mit Wälzlagern ist es erforderlich, die Kurbelwelle im Zapfen und bei mehrfach gekröpften Wellen auch in den Lagerstellen zu teilen. Die bekanntesten Teilungen dieser Art sind konische Kegelverbindungen, Klemmverbindungen und Verbindung durch Hirth-Verzahnung. Die angeführten Verbindungen sind zum Teil wenig geeignet, eine gute Verbinto dung zu gewährleisten und sind zum anderen • Teil zu teuer.To equip crankshafts with roller bearings it is necessary to use the crankshaft to share in the journal and in the case of multiple cranked shafts also in the bearings. The best-known divisions of this type are conical conical connections, clamp connections and connection through Hirth coupling. The compounds listed are some are not very suitable to ensure a good connection and, on the other hand, are • Partly too expensive.
Gemäß der Erfindung wird die Teilung der Welle durch Brechen hergestellt und mit Schrauben, ähnlich der Hirth-Verbindurig, zusammengeschraubt. Es ist bekannt, daß Teile aus Gußeisen oder gehärtetem Stahl sich nach dem Sprengen so zusammensetzen lassen, daß ihre ursprüngliche Form genau erhaltenbleibt. .According to the invention, the division of the shaft is made by breaking and with Screws, similar to the Hirth connector, screwed together. It is known that parts made of cast iron or hardened steel can be assembled after blasting so that their original shape is exactly retained. .
>Eine solche Kurbelwelle wird wie folgt hergestellt:. Die Kurbelwelle wird geschmiedet, und zwar wie bisher z. B. aus Chrom-Molybdän-Stahl; die Zapfen und Lagerstellen werden hohlgebohrt und, wie aus den Abbildüngen hervorgeht, mit entsprechenden Rillen oder Bohrungen versehen, welche einen geeigneten Bruch einleiten. Dann werden die späteren Bruchstellen nach einem Oberflächenhärtungsverfahren gehärtet und hiernach gebrochen bzw. gesprengt.> Such a crankshaft is manufactured as follows: The crankshaft is forged, as before z. B. made of chromium-molybdenum steel; the journals and bearings are drilled hollow and, as can be seen from the illustrations, with corresponding grooves or bores are provided which initiate a suitable break. Then the later break points hardened after a surface hardening process and afterwards broken or blown up.
Bei gußeisernen Wellen ist die Herstellung noch einfacher, da hierbei das Einsetzen fortfällt. In the case of cast iron shafts, production is even easier because there is no need to insert them.
Die Bruchstellen ergeben beim Zusammenschrauben einen idealen Reibungsschluß und eine verdrehungssichere Verbindung,The break points result in an ideal frictional connection when screwed together a twist-proof connection,
Die Abbildungen zeigen verschiedene Beispiele und Ausführungsformen.The figures show various examples and designs.
Abb. ι zeigt den Zapfen in der Mitte gebrochen; der Bruch wird eingeleitet durch eine zickzackförmige Rille a. Fig. Ι shows the pin broken in the middle; the break is initiated by a zigzag groove a.
Abb. 2 zeigt den Zapfen an einer Seite gebrochen. Die Rillen b und c außen und innen liegen in einer Ebene.Fig. 2 shows the pin broken on one side. The grooves b and c outside and inside lie in one plane.
In Abb. 3 ist nur innen eine Rille eingedreht. In Fig. 3 a groove is only made on the inside.
In der Ausführung nach Abb. 4 sind, wie in Abb. 2, außen und innen Rillen b und c eingedreht. Sie liegen jedoch in Achsrichtung des Zapfens versetzt zueinander.In the embodiment according to Fig. 4, as in Fig. 2, grooves b and c are screwed in on the outside and inside. However, they are offset from one another in the axial direction of the pin.
In Abb. 5 wird der Bruch durch versetzt gebohrte Löcher d eingeleitet.In Fig. 5 the fracture is initiated by holes d drilled in an offset manner.
