BESCHREIBUNG DESCRIPTION
Die Erfindung betrifft eine Vorrichtung zur direkten oder indirekten Befestigung eines Rotationskörpers auf einer Achse gemäß dem Oberbegriff des Anspruches 1. Ein Rotationskörper, der ein Lrehmoment übertragen soll, wird gegen Eigendrehung auf einer Achse im allgemeinen durch Aufkeilen, Aufschrumpfen, durch konische Bolzen, Spannstifte oder Gewindestifte gesichert.The invention relates to a device for direct or indirect Attachment of a body of revolution on an axis according to the preamble of the claim 1. A rotating body, which is to transmit a torque, is against its own rotation on an axis generally by wedging, shrinking, by conical bolts, Dowel pins or threaded pins secured.
Beim Aufkeilen wird der Rotationskörper nur in radialer Richtung auf der Achse gesichert und muß daher meist mit einem axialen Feststellelement kombiniert werden, beispielsweise mittels Gegenmuttern, Bajonettringen, Gewindestiften oder dergleichen.When wedging, the body of revolution only rises in the radial direction secured to the axis and must therefore usually be combined with an axial locking element be, for example by means of lock nuts, bayonet rings, grub screws or like that.
Diese Vorrichtungen setzen eine entsprechende Bearbeitung einer Achse voraus und lassen keinerlei Spielraum für eine Nachjustierung der radialen oder axialen Lage des Rotationskörpers auf der Achse, wenn nicht Gewindestifte verwendet werden.These devices set a corresponding machining of an axis advance and leave no room for readjustment of the radial or Axial position of the rotating body on the axis, if grub screws are not used will.
Die Verwendung von Gewindestiften verursacht jedoch meist Deformationen der Achse, so daß eine Veränderung der Lage des Rotationskörpers auf der Achse nicht mehr ohne weiteres vorgenommen werden kann.However, the use of set screws usually causes deformation the axis, so that a change in the position of the rotary body on the axis does not more can easily be done.
Aufgabe der Erfindung ist es, eine Vorrichtung zu finden, die einen Rotationskörper auf einer völlig glatten Achse sowohl in radialer als auch in axialer Richtung festhält, ohne daß die Achse beschädigt wird. Diese Vorrichtung soll auch unbegrenzte Freiheit bei der Wahl oder Nachjustierung der radialen oder axialen Lage eines Rotationskörpers.auf einer Achse geben.The object of the invention is to find a device that has a Solid of revolution on a perfectly smooth axis, both radial and axial Direction holds without the axis damaged. This device is also intended to have unlimited freedom in choosing or readjusting the radial or give the axial position of a body of revolution on an axis.
Die Erfindung löst diese Aufgabe durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmale. Eine weitere Ausgestaltung der Erfindung findet sich im Unteranspruch.The invention solves this problem by the characterizing part of claim 1 specified features. Another embodiment of the invention can be found in the subclaim.
Die Erfindung soll nun anhand eines Ausführungsbeispiels in Verbindung mit den anliegenden Zeichnungen näher beschrieben werden, in denen die Fig. 1 und 3 die Vorrichtung in axialer Richtung während die Fig. 2 und 4 einen Querschnitt durch diese Vorrichtungen zeigen.The invention will now be based on an exemplary embodiment in conjunction will be described in more detail with the accompanying drawings, in which FIGS. 1 and 3 shows the device in the axial direction while FIGS. 2 and 4 show a cross section show through these devices.
Auf einem Rotationskörper oder ähnlichem, bezeichnet mit 1, ist in den Figuren 1 und 2 eine mit Schlitzen 3 versehene Scheibe 2 mit Schrauben 4 festgeschraubt.On a body of revolution or the like, denoted by 1, in 1 and 2, a disk 2 provided with slots 3 is screwed tight with screws 4.
Im Rotationszentrum des Rotationskörpers 1 und der Scheibe 2 befindet sich je eine Bohrung in einer dem Durchmesser der Achse 5 entsprechenden Größe.Located in the center of rotation of the body of revolution 1 and the disk 2 each has a hole in a size corresponding to the diameter of the axis 5.
Die dem Rotationskörper 1 zugewendete Seite der Scheibe 2 bildet mit dem Körper einen spitzen Winkel oc Durch Anziehen der Schrauben 4 wird die Scheibe 2 mit Kräften 6 , deren Größe vom Anzugsmoment abhängt, gegen den Rotationskörper 1 gepresst.The side of the disk 2 facing the rotational body 1 forms with the body at an acute angle oc. By tightening the screws 4, the washer 2 with forces 6, the size of which depends on the tightening torque, against the rotating body 1 pressed.
Die Kraftkomponenten 6 ergeben die Kräfte 7, deren Richtung mit dem Rotationskörper 1 den Winkel α bilden. Mit dem Rotations zentrum der Achse 5 bilden sie den Winkel 900 -Aus den Kräften 7 ergeben sich die lotrecht auf das Rotationszentrum der Achse 5 gerichteten Kraftkomponenten 8.The force components 6 result in the forces 7, the direction of which with the Rotary body 1 form the angle α. With the center of rotation of the axis 5 they form the angle 900 - The forces 7 result in the perpendicular to the Center of rotation of the axis 5 directed force components 8.
Die Kräfte 8 stellen den Druck der Hohlkanten der Scheibe 2 auf die Oberfläche der Achse 5 dar.The forces 8 put the pressure of the hollow edges of the disc 2 on Surface of axis 5.
Infolge des Drucks der Scheibe 2 auf die Achse 5 kann ein Drehmoment von der Achse 5 über die Scheibe 2 und die Schrauben 4 auf den Rotationskörper 1 oder vom Rotationskörper 1 auf die Achse 5 übertragen werden.As a result of the pressure of the disk 2 on the axis 5, a torque from the axis 5 via the disk 2 and the screws 4 onto the rotating body 1 or transferred from the rotary body 1 to the axis 5.
In Fig. 3 und 4 wird eine Ausführung der Scheibe 2 gezeigt, die es ermöglicht, ein Drehmoment von der Achse 5 auf einen Rotationskörper 10, der ein Rohr oder etwas Ähnliches sein kann, über eine Scheibe 2, die Schrauben 4 und eine Zentrierscheibe 11 zu übertragen. Die Scheibe ist mit Schlitzen 3 und 9 versehen.In Fig. 3 and 4, an embodiment of the disc 2 is shown, which it allows a torque from the axis 5 to a rotating body 10, which is a Tube or something similar can be, via a washer 2, the screws 4 and a Centering disc 11 to be transferred. The disc is provided with slots 3 and 9.
Der Druck der Scheibe 2 auf die Achse 5 und den Rotationskörper 10 entsteht im Sinne der obigen Beschreibung durch Anziehen der Schrauben 4 mit Anzugsmomenten, aus denen die Kraftkomponenten 6 entstehen.The pressure of the disk 2 on the axis 5 and the rotating body 10 is created in the sense of the above description by tightening the screws 4 with tightening torques, from which the force components 6 arise.
