Description

Die Erfindung stellt eine Weiterbildung der im Patent 655 517 geschützten zusammengesetzten Kurbelwelle dar.The invention represents a further development of the compound protected in patent 655 517 Crankshaft.

Nach dem Hauptpatent werden die WeI-lenzapfen durch einen gleichachsigen Schraubenbolzen stirnseitig gegen die Kurbelwangen so stark angepreßt, daß die auftretenden Drehkräfte ohne Anwendung von Mitnehmern lediglich durch Haftreibung übertragen werden. Die Stirnflächen können einfach abgedreht oder geschliffen sein. Zur Verbesserung der Haftreibung werden gegebenenfalls dünne Zwischenlagen eines anderen Werkstoffes vorgesehen. Die aufeinandergepreßig ten Stirnflächen können auch Riefen e'rhalten, die beispielsweise eingedreht werden. Diese Art der Befestigung hat gegenüber den üblichen mit Mitnehmern versehenen Verbindungen die Vorzüge einer wesentlichen Vereinfachung der Herstellung und einer höheren Genauigkeit!According to the main patent, the shaft journals are fastened by an equiaxed screw bolt front side pressed so strongly against the crank webs that the occurring Torsional forces are transmitted without the use of drivers only by static friction. The end faces can simply be turned or ground. For improvement the static friction may result in thin intermediate layers of another material intended. The end faces pressed against one another can also receive grooves, which are screwed in, for example. This type of attachment has over the usual with drivers provided connections the advantages of a substantial simplification of manufacture and greater accuracy!

Gemäß vorliegender Erfindung werden an Stelle eines gleichachsigen Schraubenbolzens innerhalb der Wellen- oder Kurbelzapfen mehrere Schraubenbolzen vorgesehen. Die Anwendung mehrerer Einzelschrauben hat den Vorteil, daß die kleineren Schrauben ohne besondere Vorrichtung und leichter angezogen werden können. Dadurch wird insbesondere die Gefahr vermieden, daß die Teile während des Anspannens durch die Reibungskräfte gegeneinander verdreht werden. According to the present invention, instead of an equiaxed screw bolt several screw bolts are provided within the shaft or crank pin. The use of several single screws has the The advantage is that the smaller screws are tightened more easily and without a special device can be. This in particular avoids the risk that the parts during the tension are twisted against each other by the frictional forces.

Es wurde schon vorgeschlagen, die 'Schwungscheibe einer Brennkraftmaschine mit Hilfe mehrerer Schraubenbolzen an der Stirnfläche des Wellenzapfens zu befestigen. Dabei wirken die Schrauben- zugleich als Mitnehmer für die Übertragung der Drehkräfte.It has already been proposed to use the 'flywheel to attach an internal combustion engine with the help of several bolts on the end face of the shaft journal. Act here the screw at the same time as a driver for the transmission of the rotary forces.

Auf der Zeichnung ist als Ausführungsbeispiel des Erfindungsgegenstandes ein Teil einer Kurbelwelle für Brennkraftmaschinen dargestellt. Abb. 1 zeigt die Welle im Längsschnitt, während Abb. 2 einen Querschnitt durch den Lagerzapfen nach A-B der Abb. 1 darstellt. +5In the drawing, part of a crankshaft for internal combustion engines is shown as an exemplary embodiment of the subject matter of the invention. Fig. 1 shows the shaft in longitudinal section, while Fig. 2 shows a cross section through the bearing journal according to AB in Fig. 1. +5

Auf den Zapfen α ist ein Kugellager b aufgeschoben, das sich rechts gegen einen ebenen Ansatz c der Welle legt. Gegen die linke Stirnseite d des inneren Laufringes des Kugellagers liegt die glatte Stirnfläche der Schwungscheiben an. Die Anpressung erfolgt durch fünf Kopf schrauben /, deren Gewindeteil sich innerhalb des Lagerzapfens α befindet. Die Schrauben sind mit Spiel in die Schraubenlöcher eingeführt. Zwecks Zentrierung greift die Scheibe mit einer passenden Eindrehung über das Ende der Welle. In gleicher Weise wie das Kugellager könnte auch z. B. ein Zahnrad zwischen den Anpreßflächen c und d liegen.A ball bearing b is pushed onto the pin α , which lies on the right against a flat shoulder c of the shaft. The smooth face of the flywheels rests against the left end face d of the inner race of the ball bearing. The pressure is carried out by five head screws /, the threaded part of which is located within the bearing journal α . The screws are inserted into the screw holes with play. For the purpose of centering, the disc grips with a suitable recess over the end of the shaft. In the same way as the ball bearing could also, for. B. a gear between the pressing surfaces c and d lie.

Eine entsprechende Verbindung ist zwischen den Kurbelwangen g, h und dem Kurbelzapfen/ vorgesehen. Der Zapfen ist zur Aufnahme der Schraubend hohlgebohrt und auf kurzen Ansätzen der Wangen zentriert. Die Schrauben greifen mit Gewinde an der Wange h an. Sie könnten statt dessen auch hindurchgeführt und mit einer Mutter versehen sein. Die dargestellte Verbindung der getrennt hergestellten Wellenteile hat bekanntlieh den Vorzug, daß ein ungeteiltes Schubstangenlager vor dem Zusammenschrauben aufgebracht werden kann. Eine getrennte Herstellung und gleichartige Verbindung ist natürlich auch zwischen den Lagerzapfen und der Kurbelwange anwendbar, insbesondere bei einer Mehrkurbelwelle.A corresponding connection is provided between the crank webs g, h and the crank pin /. The pin is hollow drilled to accommodate the screw and centered on short shoulders of the cheeks. The screws engage with thread on the cheek h . Instead, they could also be passed through and provided with a nut. The illustrated connection of the separately manufactured shaft parts has, as is known, the advantage that an undivided push rod bearing can be applied before screwing together. A separate production and a similar connection can of course also be used between the bearing journals and the crank web, in particular in the case of a multi-crankshaft.
