Abstract

Non-positive shaft-hub connection, the hub being provided with a precision hole corresponding to the shaft journal and consisting of a plurality of essentially disc-shaped parts which are connected to one another by one or more joints, e.g. weak points in the material, in such a way that at least parts of the hole can be bent out of axial parallelism by the introduction of, preferably, axial forces at a sufficient distance from the joint and thus clamp the shaft journal.

Description

Die Erfindung betrifft eine Anordnung, um Naben kraftschlüssigThe invention relates to an arrangement for frictionally locking hubs

und damit spielfrei auf Wellen zu befestigen.and can therefore be attached to shafts without play.

Allgemein bekannt sind Verbindungen mittels konischer Ringe, konischer Zwischenbüchsen, Zwischenbüchsen mit mäanderförmigem Längsschnitt und andere Anordnungen.Generally known are connections by means of conical rings, conical Intermediate sleeves, intermediate sleeves with a meandering longitudinal section and other arrangements.

Nachteilig sind dabei zum einen aufwendige Einbaubedingungen, sehr enge erforderliche Toleranzen oder geringe Anpassmöglichkeit an verschiedene Wellendurchmesser.On the one hand, the installation conditions are very disadvantageous tight required tolerances or low adaptability to different shaft diameters.

Die Erfindung dient der Vermeidung der genannten Nachteile.The invention serves to avoid the disadvantages mentioned.

Erfindungsgemäß läßt sich dies erreichen, wenn die Nabe mit einer dem Wellenzapfen entsprechenden genauen Bohrung versehen ist und aus mehreren, im wesentlichen scheibenförmigen Teilen besteht, die durch ein oder mehrere Gelenke z,B. Materialschwachstellen so miteinander verbunden sind, daß zumindest Teile der Bohrung durch Einleitung vorzugsweise axialer Kräfte in ausreichendem Abstand zum Gelenk aus der Achsparallelität verbogen werden können und somit den Wellenzapfen klemmen.According to the invention this can be achieved if the hub with a the shaft journal corresponding exact hole is provided and from several, im consists of essential disc-shaped parts, which are formed by one or more joints z, B. Material weaknesses are so connected that at least parts of the Drilling by introducing preferably axial forces at a sufficient distance from the Joint can be bent out of axis parallelism and thus the shaft journal clamp.

Im folgenden ist die Erfindung anhand zweier Ausführungsbeispiele (Bilder 1 u. 2) erläutert.In the following the invention is based on two exemplary embodiments (Pictures 1 and 2).

Eine Nabe wird beispielsweise entsprechend Bild 1 oder 2 mit Bohrung (1) über einen Wellenzapfen geschoben. Die Nabe weist dabei quer zur Achsrichtung verlaufende Schlitze (5), Querbohrungen (4), sonstige Aussparungen oder eine Kombination aus solchen in der Form auf, daß mindestens 2, beispielsweise scheibenförmige Nabenteile um Schwachstellen (A-A) aus der Planlage verbogen werden können. Dazu kann in ausreichendem Abstand zu (A-A) Axialkraft auf mindestens 2 Teile, beispielsweise durch Schrauben (3) ausgeübt werden. Querschnitt (A-A) muß dabei ausreichend dimensioniert sein, um die auftretenden Kräfte zu übertragen. Die Bohrungsflächen (2) verringern bei Verformung den achsparallelen freien Durchlass und klemmen damit auf dem Wellenzapfen.A hub is, for example, with a hole as shown in Figure 1 or 2 (1) pushed over a shaft journal. The hub points transversely to the axial direction Running slots (5), cross bores (4), other recesses or a combination from such in the form that at least 2, for example disc-shaped hub parts can be bent out of flatness around weak points (A-A). This can be done in sufficient Distance to (A-A) axial force on at least 2 parts, e.g. by screws (3) be exercised. Cross-section (A-A) must be sufficiently dimensioned to transfer the forces that occur. The bore surfaces (2) decrease at Deformation of the axially parallel free passage and thus jam on the shaft journal.

Die Schwachstellen (A-A) können auch durch geeignete Gelenke ersetzt werden.The weak points (A-A) can also be replaced by suitable joints will.

Um den Planschlag der einzelnen Nabenteile im geklemmten Zustand zu reduzieren oder zu vermeiden, kann die Nabe vor Anbringen der Fertigbohrung (1) entgegen der Klemmrichtung verformt und so fertig gebohrt werden. Bei entsprechender Verformung ist damit eine ausreichende Klemmung bei Planlage aller Nabenteile möglich.To the axial runout of the individual hub parts in the clamped state reduce or avoid the hub before making the finished bore (1) deformed against the clamping direction and thus drilled to completion. With the appropriate Deformation is thus possible with sufficient clamping when all hub parts are flat.
