Abstract

The assembly consists of tool (1) screwed to the face of ring body (3) fitted in a sealed manner to the other part (5) of the ring body. The two parts are mounted together by bolts (6) and the division surface is sealed by ring seal (14). Within the body of the complete ring a hollow space (7) is created with a relatively thin wall (4) adjacent to the surface of shaft (2). At one point of the outer wall of the jacket a non-return nipple (8) is provided. When hydraulic pressure is applied on this nipple, wall (4) deforms with a curvature towards the shaft surface and provides a positive locking of the ring on the shaft.

KLEMMRING Klemmring dienen zur Befestigung von Spannstücken, wie Werkzeugen und Werkstücken, auf Wellen. Es ist bekannt, sie hydraulische zu betätigen. Dazu wird in dem zur Aufnahme der Welle dienenden rundzylindrischen Hohlraum des Klemmrings ein Stahlzylinder geringer Wandstärke so eingesetzt, dass er über einen hinter ihm im Klemmring angeordneten ringförmigen Druckraum mit hydraulischem Medium beaufschlagt und gegen die Welle zu vorgewölbt werden kann, sodass eine leistungsfähige Klemmverbindung zwischen Klemmring und Welle hergestellt wird.CLAMPING RING Clamping rings are used to fasten clamping pieces such as tools and workpieces, on shafts. It is known to operate them hydraulically. In addition is in the round cylindrical cavity of the clamping ring serving to accommodate the shaft A steel cylinder of small wall thickness is used so that it has one behind it arranged in the clamping ring annular pressure chamber acted upon with hydraulic medium and can be bulged against the shaft, so that a powerful clamping connection is made between the clamping ring and the shaft.

Die Erstellung solcher Klemmringe unter Sicherstellung enger Toleranzen, insbesondere die Ilerstellung gesonderter, dünnstwandiger Stahlzylinder und deren toleranzgerechter Einbau bieten erhebliche Schwierigkeiten und sind sehr aufwendig.The creation of such clamping rings while ensuring tight tolerances, in particular the production of separate, thinnest-walled steel cylinders and their Tolerance-compliant installation present considerable difficulties and are very expensive.

Die Neuerung schlägt einen neuartigen Klemmring vor, welcher diese Nachteile vermeidet, insbesondere ohne gesonderten Stahlring arbeitet.The innovation suggests a new type of clamping ring, which this Avoids disadvantages, especially works without a separate steel ring.

Eine beispielsweise Ausführung ist in den Figuren 1 und 2 in zwei Varianten dargstellt.An example embodiment is shown in Figures 1 and 2 in two Variants shown.

Figur 1 ist ein schematischer Axialschnitt durch einen im Wesentlichen rundzylindrischen zweiteiligen Klemmring entsprechend der Neuerung.Figure 1 is a schematic axial section through an essentially round cylindrical two-part clamping ring according to the innovation.

Darin ist 1 das aufzuspannende Spanntück, in diesem Beispiel ein Kreismesser. 2 ist die Welle, mit welcher das Kreismesser 1 präzise verspannt wird.3 ist ein erstes Teilstück des Klemmrings mit der Spannfläche 4. Das Kreismesser ist mit dem ersten Teilstück 3 verbunden, im vorliegenden Beispiels mittels mehrerer Schrauben 1'.1 is the clamping piece to be clamped, in this example a circular knife. 2 is the shaft with which the circular knife 1 is precisely clamped. 3 is a first section of the clamping ring with the clamping surface 4. The circular knife is with the first part 3 connected, in the present example by means of several screws 1'.

DAs erste Teilstück 3 und das zweite Teilstück 5 sind miteinander verbunden durch mehrere Schrauben 6, sodass zwischen beiden ein ringförmiger Druckraum 7 entssteht, was durch Ausnehmungen in einem oder dem anderen oder in beiden Teilstücken bewirkt wird.The first section 3 and the second section 5 are with one another connected by several screws 6, so that an annular pressure space between the two 7 arises what through recesses in one or the other or in both parts is effected.

Der Druckraum 7 ist mit hydraulischem Medium gefüllt und, KLEMMRING zwecks Aufbau höheren Drucks,wird über den Rückschlagnippel 8 weiteres Medium eingeführt. Dadurch wird die Spannfläche 9( des Teilstücks 1 nach innen radial vorgewölbt und mit grosser Spannkraft gegen die Welle 2 gedrückt. Zwecks Entspannung wird das Rückschlagventil entfernt oder eine andere Entlastungseinrichtung vorgesehen.The pressure chamber 7 is filled with hydraulic medium and, CLAMPING RING In order to build up higher pressure, further medium is introduced via the non-return nipple 8. As a result, the clamping surface 9 (of the section 1 is arched radially inward and pressed against the shaft 2 with great clamping force. The check valve is used for relaxation removed or another relief device provided.

Figur 2 ist eine schematische Teildarstellung einer anderen beispielsweisen Ausführung eines solchen Klemmrings, bei welchem der Druckaufbau im Druckraum 7 nicht über einen Anschluss an eine ausserhalb des Klemmrings liegende Druckquelle erfolgt, sondern durch Betätigung eines im Klemmring selbst angeordncten angeordneten Druckerzeugers. Er besteht aus der Stellschraube 9 mit Innensechskant, dem Kolben 10 mit seiner Dichtung jj, welche beide in der zylindrischen Bohrung 13 geführt werden, deren freibleibender Raum ebenso wie der zum Druckraum 7 führende Druckkanal 12 mit Medium gefüllt sind. Wird die Stellschraube 9 mittels eines Sechskantschlüssels in die Bohrung 13 hineingeschraubt, so drückt der Kolben 14 mit seiner Dichtung 15 auf das hydraulische Medium, welches die Restbohrung 13, den Druckkanal 12 und den Druckraum 7 anfüllt, sodass eine entsprechend den dem Flächenverhältnis zwischen dem Querschnitt des Kolbens 14 einerseits und der Spannfläche 4 andererseits übersetzte Spannkraft auf die Spannfläche 4 wirksam wird.Figure 2 is a partial schematic illustration of another example Execution of such a clamping ring, in which the pressure build-up in the pressure chamber 7 does not have a connection to a pressure source outside the clamping ring takes place, but by actuating one arranged in the clamping ring itself Pressure generator. It consists of the adjusting screw 9 with a hexagon socket, the piston 10 with its seal jj, both of which are guided in the cylindrical bore 13 whose free space as well as the pressure channel leading to the pressure chamber 7 12 are filled with medium. If the adjusting screw 9 is made using a hexagon wrench screwed into the bore 13, the piston 14 presses with its seal 15 to the hydraulic medium, which the remaining bore 13, the pressure channel 12 and the pressure chamber 7 fills, so that a corresponding to the area ratio between the cross section of the piston 14 on the one hand and the clamping surface 4 on the other hand translated Clamping force on the clamping surface 4 becomes effective.

In beiden Figuren sind 14 und 15 Dichtungen.In both figures 14 and 15 are seals.

Die hydraulische Einrichtung kann sowohl im einen wie im anderen wie in beiden Teilstücken angeordnet sein.The hydraulic device can be used either in one or in the other be arranged in both sections.

Das Spannstück 1 kann auch auf anderere als die dargestellte Weise mit dem ersten Teilstück verbunden sein.The clamping piece 1 can also be used in a manner other than that shown be connected to the first section.
