Abstract
Description
Die Erfindung betrifft eine spielfreie Verbindung zur Übertragung von begrenzten Drehmomenten von einer treibenden Welle auf ein anzutreibendes Gerät, vorzugs weise leichtgängige Meßgeräte oder Drehgeber.The invention relates to a play-free connection for the transmission of limited Torques from a driving shaft to a device to be driven, preferably as smooth-running measuring devices or encoders.
Für den Antrieb von Meßgeräten und Drehgebern, sind verschiedene Kupplungen bekannt, die ihren Ursprung im Maschinenbau haben. Die EP 0 682 229A be schreibt zur drehfesten Ankupplung der Geberwelle, an eine zu erfassende Meßwel le, eine Spannzange, wobei ein Außenkonus in einen Innenkonus gezogen wird, um so die Meßwelle zu spannen. Die dazu erforderliche Spannschraube verläuft in axialer Richtung durch die Geberwelle.Various couplings are used to drive measuring devices and encoders known that have their origin in mechanical engineering. EP 0 682 229A writes to the rotationally fixed coupling of the encoder shaft to a measurement world to be recorded le, a collet, whereby an outer cone is pulled into an inner cone to so to tension the measuring shaft. The clamping screw required for this runs in axial direction through the encoder shaft.
Es sind auch Kupplungen zur reibungsfreien, relativ genauen Winkelübertragung zwischen einem Antriebs- und einem Abtriebsteil bekannt, bei denen die Verbindung zwischen Antiebs- und Abtriebsteil über zwei Federparallelführungen erfolgt, die je mit Abstand voneinander parallel verlaufende, gestreckte Federn aufweisen, deren Enden je starr miteinander verbunden sind und bei denen die einen Enden der Federn, der einen Parallelführung mit dem Antriebsteil und diejenigen der anderen Enden der Federn beider Parallelführungen, starr miteinander verbunden sind. Eine derartige Kupplung ist in der schweizer Patentschrift Nr. 381 028 beschrieben. They are also couplings for smooth, relatively precise angle transmission known between a drive and an output part, in which the connection between the drive and output part via two spring parallel guides, each have spaced parallel, elongated springs, the Ends are rigidly connected to each other and in which one end of the Springs, one in parallel with the drive part and those of the other Ends of the springs of both parallel guides are rigidly connected. A such coupling is described in Swiss Patent No. 381 028.
Eine Weiterentwicklung der CH 381 028 beinhaltet die DE PS 30 38 072. Diese Kupplung enthält als Verbindungsteil einen Ring aus Kunststoff, an dem zwei Paare von parallelen Federarmen angeformt sind, deren Enden mit Augen versehen sind und paarweise in Zapfen an je einer Scheibe eingehängt werden, wobei eine Schei be auf der Antriebs- und die andere Scheibe auf der Abtriebswelle befestigt ist.DE PS 30 38 072 contains a further development of CH 381 028. This Coupling contains a plastic ring as a connecting part, on which two pairs are formed by parallel spring arms, the ends of which are provided with eyes and hung in pairs in pegs on each disc, one disc be attached to the drive shaft and the other disk to the output shaft.
Alle diese bekannten Kupplungen weisen die Nachteile auf, daß sie teuer in der Herstellung sind und viel Raum einnehmen. Je nach Platzverhältnissen ist auch die Montage schwierig.All these known couplings have the disadvantages that they are expensive in the Are manufacturing and take up a lot of space. Depending on the space available, the Assembly difficult.
Der Erfindung liegt die Aufgabe zugrunde, eine Kupplung bzw. eine Verbindung zwischen dem treibenden Maschinenteil und dem anzutreibenden Gerät zu schaf fen, welches die vorgenannten Nachteile nicht besitzt.The invention has for its object a coupling or a connection between the driving machine part and the device to be driven fen, which does not have the aforementioned disadvantages.
Diese Aufgabe wird gemäß der Erfindung durch die Merkmale des kennzeichnen den Teiles des Anspruchs 1 gelöst, daß in das Zentrum der antreibenden Welle eine Bohrung eingebracht wird und die anzutreibende Welle mit mindestens drei axialen, am Umfang dieser Welle, gleichmäßig verteilten Kerben, ausgebildet ist.This object is characterized by the features of the invention solved the part of claim 1 that in the center of the driving shaft Bore is introduced and the shaft to be driven with at least three axial, is formed on the circumference of this shaft, evenly distributed notches.
Beim Einwalzen der Kerben entstehen beiderseits der Kerben Wülste, die sich beim Eindrücken der Kerbwelle, in die zylinderische Bohrung der antreibenden Welle, elastisch verformen. Diese Verbindung hat die Vorteile, daß sich die Kerbwelle in der Bohrung verspannt, zentriert, axial ausrichtet, spielfrei und rüttelsicher ist. Wei tere Vorteile dieser Verbindung sind, daß sie platzsparend, preiswert herzustellen und wiederholt verwendbar istWhen the notches are rolled in, ridges are formed on both sides of the notches, Pushing the notch shaft into the cylindrical bore of the driving shaft, deform elastically. This connection has the advantages that the notch wave in the bore is braced, centered, axially aligned, free of play and vibration-proof. Wei Other advantages of this connection are that it is space-saving, inexpensive to manufacture and can be used repeatedly
Weitere Merkmale der Erfindung ergeben sich aus der folgenden Beschreibung, in Verbindung mit den Ansprüchen und Zeichnungen.Further features of the invention result from the following description, in Connection with the claims and drawings.

The assembly aid ( 7 ) is screwed into the thread ( 6 ) in order to press the shaft ( 2 ) into the bore ( 8 ) at the front of the shaft end ( 9 ) without damaging the device ( 1 ).
Die Öffnung (11) in der Abdeckung (10) wird anschließend mit einem nicht darge stellten Stopfen verschlossen. Zur Demontage des Gebers (1) wird die Montagehilfe (7) wieder in das Gewinde (6) eingeschraubt und der Geber (1) über die Welle (2) aus der Antriebswelle (9) herausgezogen.The opening ( 11 ) in the cover ( 10 ) is then closed with a plug not shown Darge. To disassemble the encoder ( 1 ), screw the assembly aid ( 7 ) back into the thread ( 6 ) and pull the encoder ( 1 ) out of the drive shaft ( 9 ) via the shaft ( 2 ).
Die Bohrung (12) und/oder der Bund (13) sind angebracht, um ein Abziehwerkzeug anzusetzen. Je nach Ausführung und Gegebenheiten kann die Geberwelle anstelle des Innengewindes (6) mit einem Außengewinde und die Montagehilfe (7) mit einem Innengewinde ausgeführt werden. Um den feststehenden Teil (14) des Gebers (1) zu fixieren, ist am Teil (14) ein Halteblech (15) befestigt, das mit einem Maschinen teil (16) lösbar verbunden ist. Die tragende Verbindung zwischen dem Geber (1) und dem Wellenende (9) wird durch die Kerben (4) realisiert.The bore ( 12 ) and / or the collar ( 13 ) are made to attach a puller. Depending on the design and circumstances, the encoder shaft can be designed with an external thread instead of the internal thread ( 6 ) and the mounting aid ( 7 ) with an internal thread. In order to fix the fixed part ( 14 ) of the encoder ( 1 ), a holding plate ( 15 ) is attached to the part ( 14 ), which is detachably connected to a machine part ( 16 ).
