Description
Drehschlüssiges Verbindungselement zweier rotierender TeileRotationally locking connecting element of two rotating parts
Die Erfindung betrifft eine drehschlüssiges Verbindungselement zweier rotierender Teile, insbesondere einer Antriebswelle einer Bohrmaschine oder ähnlichem und der Welle des angetriebenene Werkzeughalters.The invention relates to a rotationally locking connecting element of two rotating parts, in particular a drive shaft of a drilling machine or the like and the shaft of the driven tool holder.
Drehschlüssige Verbindungen zwischen einer Antriebswelle und einer Abtriebswelle werden häufig dadurch hergestellt, daß auf einer der beiden Wellen ein Innensechskant über einen Außensechskant, der an der anderen Welle angesetzt ist, geschoben wird, so daß die beiden Sechskante mit ihren Flächen planparallel zueinander stehen und so eine drehschlüssige Verbindung erzeugen. Solange diese Verbindung manuell hergestellt werden kann, besteht die Möglichkeit, die beiden Achsen von Innen- und Außensechskant so zueinander zu verdrehen, daß die gegenüberliegenden Flächen jeweils planparallel zueinander orientiert werden, so daß ein Ineinanderschieben möglich ist. Soll eine derartige Verbindung jedoch automatisch oder halbautomatisch hergestellt werden, wobei der Bedienende keine Möglichkeit hat, in die Orientierung der beiden Achsen eingreifen zu können, so besteht die Notwendigkeit, daß sich die beiden Achsen automatisch in der richtigen Position orientieren.Rotationally locked connections between a drive shaft and an output shaft are often made by sliding a hexagon socket on one of the two shafts over an hexagon socket that is attached to the other shaft, so that the two hexagons are parallel to each other with their surfaces, thus creating a rotationally locked connection. As long as this connection can be made manually, it is possible to rotate the two axes of the hexagon socket and hexagon socket relative to each other so that the opposing surfaces are aligned parallel to each other, so that they can be pushed into each other. However, if such a connection is to be made automatically or semi-automatically, whereby the operator has no possibility of intervening in the orientation of the two axes, it is necessary for the two axes to automatically orient themselves in the correct position.
Es ist Aufgabe der Erfindung, ein drehschlüssiges Verbindungselement darzustellen, bei dem sich im Falle eines koaxialen Zusammenschiebens beider Hälften des Verbindungselements automatisch die richtige Orientierung der beiden Verbindungshälften des Verbindungselements einstellt.It is the object of the invention to provide a rotationally locking connecting element in which, in the event of a coaxial pushing together of both halves of the connecting element, the correct orientation of the two connecting halves of the connecting element is automatically established.
Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The problem is solved by the characterizing features of claim 1.
Demgemäß werden zwei zueinander komplementäre Sechskantstücke so gestaltet, daß auf dem Innensechskant eine Vielzahl von in axialer Richtung weisenden Zähnen angeordnet sind, denen auf der entsprechenden gegenüberliegenden Seite des Außenvielkants eine Fläche gegenübersteht, die in Zusammenwirkung mit dem Zahn bei axialem Aufeinanderzubewegen der beiden Elemente ein Drehmoment erzeugt, welches eine relative Rotation der Teile bewirkt, bis eine Orientierung erreicht ist, bei der die jeweils gegenüberliegenden Flächen des Vielkantes parallel zueinander orientiert sind. Die Erfindung ist anhand der Figuren näher beschrieben. Darin ist im übrigen folgendes dargestellt:Accordingly, two hexagon pieces that complement each other are designed in such a way that a large number of teeth pointing in the axial direction are arranged on the hexagon socket, which are opposed by a surface on the corresponding opposite side of the external polygon, which, in interaction with the tooth, generates a torque when the two elements move axially towards each other, which causes a relative rotation of the parts until an orientation is reached in which the opposite surfaces of the polygon are oriented parallel to each other. The invention is described in more detail with reference to the figures. The figures also show the following:
Figur 1: Erfindungsgemäßer Innensechskant. Figur 2: Erfindungsgemäßer Außensechskant.Figure 1: Hexagon socket according to the invention. Figure 2: Hexagon socket according to the invention.
Figur 1 zeigt verschiedene Schnitte durch einen erfindungsgemäßen Innensechskant 1.1, welcher den ersten Teil des Verbindungselements darstellt. Anhand der Schnitte ist gezeigt, wie jeder einzelnen Fläche 2.1 des Innensechskants an der einen Seite ein etwa V-förmiger ZahnFigure 1 shows various sections through a hexagon socket 1.1 according to the invention, which represents the first part of the connecting element. The sections show how each individual surface 2.1 of the hexagon socket has an approximately V-shaped tooth on one side.
3.1 zugeordnet ist, der in Verbindung mit dem in der Figur 2 gezeigten komplementären zweiten Teil des Verbindungselementes einem Außensechskant 1.2 mit einer ebenen Anfasung 3.2 je Außenfläche 2.2 des Außensechskantes3.1, which in conjunction with the complementary second part of the connecting element shown in Figure 2 has an external hexagon 1.2 with a flat chamfer 3.2 per outer surface 2.2 of the external hexagon
1.2 ein Drehmoment ausübt, welches die beiden Teile des Verbindungselementes so lange dreht, bis deren entsprechende Flächen zueinander parallel stehen und ein Einführen des Außensechskantes 1.2 in den Innensechskant 1.1 möglich ist.1.2 exerts a torque which rotates the two parts of the connecting element until their corresponding surfaces are parallel to each other and the external hexagon 1.2 can be inserted into the internal hexagon 1.1.
