Abstract

The method involves sliding a connecting piece with a tubular end over a profiled inner part of a hollow shaft. An outer part is completely or partially molded in the profile inner part by a profiled tool or a flexible reduction tool, which is pressed or expanded together such that the tool constricts inward and/or lies outside. Circular flanges or embossments are superimposed on the profiled inner part.

Description

Konstruktive Lösung mit entsprechendem Verfahren zur Darstellung einer Verbindung, die in der Lage ist, hohe Drehmomente zu übertragen und gleichzeitig auch definierte Axialkräfte aufzunehmen. Bei Überschreiten dieser Axialkräfte teleskopiert die Verbindung definiert, ohne auszuknicken.constructive solution with a corresponding method for the preparation of a compound which is able to transmit high torques and at the same time also defined axial forces take. When crossing these axial forces telescopically defines the connection without kinking.

Hierzu wird über das profilierte Innenteil (Massiv- oder Hohlwelle) ein Anschlussstück aus Rohr oder mit rohrförmigem Ende geschoben. Durch eine geeignete Vorrichtung wird dann das Außenteil ganz oder teilweise in das Profil des Innenteils geformt (1). Für diesen Umformarbeitsgang kann entweder ein ebenfalls profiliertes Werkzeug verwendet werden oder auch ein anpassungsfähiges Reduzierwerkzeug, beispielsweise mit einem Elastomerring, der so zusammengepresst wird, dass er sich nach innen einschnürt. Besonders gut geeignet ist die elektromagnetische Pulsumformung, mit der völlig berührungslos das äußere Teil auf die profilierte Welle aufgeformt wird und dabei Form- und Kraftschluss bekommt. In besonderen Fällen kann mit der elektromagnetischen Pulsumformung auch eine lokale Schweißverbindung erzeugt werden.For this purpose, a connection piece made of tube or tubular end is pushed over the profiled inner part (solid or hollow shaft). By a suitable device, the outer part is then completely or partially formed in the profile of the inner part ( 1 ). Either an equally profiled tool or an adaptive reduction tool, for example with an elastomeric ring, which is pressed together in such a way that it constricts inwards, can be used for this forming operation. The electromagnetic pulse transformation is particularly well suited, with which the outer part is molded onto the profiled shaft in a completely contactless manner, thereby achieving positive and non-positive fit. In special cases, a local weld can be generated with the electromagnetic pulse transformation.

Selbstverständlich gibt es auch die umgekehrte Lösung, dass beispielsweise eine Hohlwelle ein Innenprofil aufweist und das Anschlussstück dann mit seinem rohrförmigen Ende in diese Hohlwelle hineingeschoben wird. Durch Aufweiten von innen radial nach außen ergibt sich dann eine vergleichbare Verbindung wie vorstehend beschrieben.Of course there it's also the opposite solution, that, for example, a hollow shaft has an inner profile and then the connector with its tubular End is pushed into this hollow shaft. By widening of inside radially outward then results in a comparable connection as described above.

Zur Erhöhung der axialen Betriebs- und Crashkraft kann zusätzlich noch ein Profil in Umfangsrichtung dem Längsprofil überlagert werden, d. h. beispielsweise eine oder mehrere umlaufende Sicken, Einprägungen o. ä. (s. 2).To increase the axial operating and crash force, a profile in the circumferential direction can additionally be superimposed on the longitudinal profile, ie, for example, one or more circumferential beads, indentations or the like (see FIG. 2 ).

Eine vorzugsweise Anwendung stellen Gelenkwellen oder Kardanwellen dar, die bei einer bestimmten Axialkraft (Crash) teleskopieren sollen, ohne abzureißen oder auszuknicken.A preferably use drive shafts or cardan shafts, which are to telescope at a certain axial force (crash), without demolish or kink.
