Abstract
Vorgeschlagen ist eine Unwuchtwelle zum Ausgleich von Massenkräften und/oder Massenmomenten einer Brennkraftmaschine, umfassend eine Trägerwelle (1) und eine an deren Außenumfang befestigte Unwuchtmasse (2). Die Befestigung der Unwuchtmasse an der Trägerwelle soll mittels eines die Trägerwelle und die Unwuchtmasse umschließenden Spannrings (3) erfolgen, der die Unwuchtmasse radial gegen die Trägerwelle spannt.Proposed is an imbalance shaft to compensate for inertial forces and / or moments of inertia of an internal combustion engine, comprising a carrier shaft (1) and an outer mass attached imbalance mass (2). The attachment of the unbalanced mass to the support shaft should be effected by means of a carrier shaft and the unbalanced mass enclosing clamping ring (3), which biases the unbalanced mass radially against the carrier shaft.
Description
Die Erfindung betrifft eine Unwuchtwelle zum Ausgleich von Massenkräften und/oder Massenmomenten einer Brennkraftmaschine. Die Unwuchtwelle umfasst eine Trägerwelle und eine an deren Außenumfang befestigte Unwuchtmasse.The invention relates to an imbalance shaft for balancing mass forces and / or mass moments of an internal combustion engine. The imbalance shaft comprises a carrier shaft and an imbalance mass attached to its outer circumference.
Gebaute Unwuchtwellen mit gefügten Unwuchtmassen sind beispielsweise aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Unwuchtwelle der eingangs genannten Art mit möglichst hoher Modularität anzugeben.The present invention has for its object to provide an imbalance shaft of the type mentioned with the highest possible modularity.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruchs 1. Demnach soll die Befestigung der Unwuchtmasse an der Trägerwelle mittels eines die Trägerwelle und die Unwuchtmasse umschließenden Spannrings erfolgen, der die Unwuchtmasse radial gegen die Trägerwelle spannt. Die Modularität der Unwuchtwelle resultiert aus der Spannringbefestigung der Unwuchtmasse, deren Größe an unterschiedliche Unwuchten bei ansonsten hohem Gleichteileanteil der Unwuchtwellen vergleichsweise einfach anpassbar ist.The solution of this problem arises from the features of
Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind den Unteransprüchen entnehmbar. Insbesondere soll die Trägerwelle im Befestigungsbereich der Unwuchtmasse als (im IHU- oder Hydroforming-Verfahren) innenhochdruckumgeformtes Hohlprofil ausgebildet sein. Die IHU-Umformung ermöglicht es, dass die Spannringe und die Unwuchtmasse sowohl in umfänglicher als auch in axialer Richtung der Unwuchtwelle formschlüssig am umgeformten Hohlprofil der Trägerwelle befestigt sind.Advantageous developments and refinements of the invention can be taken from the subclaims. In particular, the support shaft should be formed in the fastening region of the unbalanced mass as (in the hydroforming or hydroforming process) hydroformed hollow profile. The hydroforming makes it possible that the clamping rings and the imbalance mass are secured in both the circumferential and in the axial direction of the imbalance shaft form-fitting manner on the reshaped hollow profile of the support shaft.
