Description

Die Erfindung betrifft eine Vorrichtung, mit welcher zylindrische Zapfen, Wellen, Dorne, Rohre od, dgl, in entsprechenden Bohrungen durch Verspannen gegen Verdrehen und axiales Verschieben gesichert werden können.The invention relates to a device with which cylindrical Pins, shafts, mandrels, pipes or the like in corresponding bores by bracing can be secured against twisting and axial displacement.

Die Technik kennt zahlreiche Mittei, um Zapfen oder Wellen in Bohrungen zu verspannen. In der Hauptsache sind es kreisrunde Konusverbindüngen mit oder ohne geschlitzte Hülsen. Daneben gibt es sogenannte Expansionsdorne, bei welchen ungeschlitzte, dünnwandige Hülsen von innen her kreisförmig gedehnt werden. Schließlich sind noch die Schrumpfungen durch Wärme- oder Kälteanwendung zu erwähnen.The technology knows numerous means around pins or shafts in bores to brace. Mainly there are circular conical connections with or without slotted sleeves. There are also so-called expansion mandrels, in which unslotted, thin-walled sleeves are stretched circularly from the inside. Finally are still to mention the shrinkage caused by the application of heat or cold.

Die Spannmittel mit geschlitzten Hülsen haben den Nachteil, daß die Zentrierung nicht genau ist. Die Expansionsdorne gestatten andererseits nur eine geringe Aufweitung. Die Schrumpfungen hingegen sind teuer und vielfach nicht umkehrbar.The clamping means with slotted sleeves have the disadvantage that the Centering is not accurate. The expansion mandrels, on the other hand, only allow one slight expansion. The shrinkage, however, is expensive and often irreversible.

Die Vorrichtung zum .konzentrischen Verspannen gemäß der Erfindung zentriert sehr genau, überbrückt geringe Durchmesserunterschiede und ist einfach herzustellen.The device for concentric bracing according to the invention centers very precisely, bridges small differences in diameter and is simple to manufacture.

Die Abbildung zeigt die Vorrichtung zum konzentrischen Verspannen beispielsweise für einen zylindrischen Zapfen in einer entsprechenden Bohrung. Die Bohrung des inneren Zylinders a und der Umfang des äußeren Zylinders b sind im entspannten Zustand kreisrund. Die äußere Begrenzungsfläche des inneren Zylinders a und die innere Begrenzungsfläche des äußeren Zylinders b werden im Querschnitt von einer Kurve begrenzt, die abweichend von der Kreisform vorzugsweise aus mehreren Kreisbogen zusammengesetzt ist, deren Radien kleiner als der Radius der Berührungsfläche sind. Beide Ringe werden in der gezeichneten Zusammenstellung zwischen die Welle und die entsprechend größere Bohrung gebracht und gegeneinander verdreht.The figure shows the device for concentric clamping for example for a cylindrical pin in a corresponding bore. the The bore of the inner cylinder a and the circumference of the outer cylinder b are relaxed State circular. The outer boundary surface of the inner cylinder a and the inner boundary surface of the outer cylinder b are in cross section of a Curve limited, which, deviating from the circular shape, preferably consists of several circular arcs is composed, the radii of which are smaller than the radius of the contact surface. Both rings are in the drawn arrangement between the shaft and the brought a correspondingly larger hole and twisted against each other.

Weist der Zäpfen .oder das Loch bzw. weisen beide das obenerwähnte Profil auf, so ist nur ein Ring bzw. kein Ring erforderlich.Does the cone. Or the hole or both show the above-mentioned Profile, only one ring or no ring is required.

In besonderen Fällen können zwischen den Profilen Wälzkörper vorgesehen werden, woben beide Ringe im verspannten Zustand mit bekannten Mitteln gegen Relativdrehung gesichert werden.In special cases, rolling elements can be provided between the profiles be, with both rings in the clamped state with known means against relative rotation secured.
