Abstract
Description
Die vorliegende Erfindung betrifft mechanische Überlast-Kupplungen mit einem beim Auftreten von Überlast axial verschieblichen Kupplungsteil bzw. Schaltring mit einem mechanischen oder induktiven Sensor zur Ermittlung des Schaltzustandes der Kupplung.The The present invention relates to mechanical overload clutches having a when overload occurs axially displaceable coupling part or switching ring with a mechanical or inductive sensor for determining the switching state of the clutch.
Mechanische Überlastkupplungen der meisten gebräuchlichen Bauarten haben die Eigenschaft, daß beim Auftreten einer Überlast ein Ring auf der Kupplung um einen bestimmten Weg (Hub) in axialer Richtung verschoben wird. Zur Überwachung des Schaltzustandes der Überlastkupplung werden extern angebrachte Sensoren (mechanische Schalter oder induktive Näherungsschalter) verwendet, die die Verschiebung des Rings feststellen und damit eine Überlast im Antriebsstrang erkennen. Somit kann der Antrieb abgeschaltet und Schaden vermieden werden.Mechanical overload clutches most in use Types have the property that when overload occurs a ring on the coupling around a certain distance (stroke) in the axial direction is moved. For monitoring the switching state of the overload clutch be externally mounted sensors (mechanical switches or inductive Proximity switch) used, which determine the displacement of the ring and thus an overload recognize in the drive train. Thus, the drive can be switched off and damage can be avoided.
Probleme treten auf, wenn bei Planlauffehlern der Kupplung oder axialer Verschiebung der Welle, auf der die Kupplung montiert ist (Lagerspiel, Wärmedehnung) Zustände eintreten können, bei denen der Schaltpunkt des externen Sen sors nicht mehr stimmt und so eine tatsächlich auftretende Überlast nicht mehr erkannt wird oder irrtümlich eine Überlast abgefühlt wird, wo gar keine vorhanden ist.issues occur when, in case of run-out errors of the coupling or axial displacement the shaft on which the coupling is mounted (bearing clearance, thermal expansion) conditions can enter where the switching point of the external Sen sors no longer true and one actually occurring overload is no longer recognized or mistakenly an overload is sensed, where none is available.
Hiernach ist es die der vorliegenden Erfindung zugrunde liegende Aufgabe, bei den in Rede stehenden mechanischen Überlastkupplungen das Abfühlen des Schaltzustandes der Kupplung unabhängig zu machen von irgendwelchen zufällig bestimmten Einflüssen auf die tatsächlich axiale Position oder Gesamtkupplung bzw. des darauf befindlichen Schaltringes.hereafter it is the object underlying the present invention, at the mechanical overload clutches in question the sensing of the Switching state of the clutch to make independent of any fortuitously certain influences to the actual axial position or total clutch or the one located thereon Switching ring.
Diese Aufgabe wird durch die im Anspruch 1 angegebene Merkmalskombination gelöst. Diese Lösung hat gegenüber den bekannten Anordnungen zur Überwachung des Schaltzustandes einer Überlastkupplung den besonderen Vorteil, dass unabhängig von der axialen Lage durch Wärmedehnung, Lagerspiel o. ä. eine sichere Abschaltung erfolgt ohne aufwändige Justierarbeiten des Schalters bzw. Sensors.These The object is achieved by the feature combination specified in claim 1 solved. This solution has opposite the known arrangements for monitoring the switching state of an overload clutch the particular advantage that regardless of the axial position by Thermal expansion, Bearing game o. Ä. a safe shutdown takes place without time-consuming adjustments of the switch or sensors.
Mehrere Ausführungsformen der erfindungsgemäßen Abtastung des Überlastfalles werden anhand der beigefügten Zeichnung erläutert, wobei die eigentliche mechanische Kupplung, die im Schnittbild gezeigt ist, schon seit längerem zum bekannten Stand der Technik gehört.Several embodiments the scanning according to the invention of the overload case are based on the attached Drawing explained, being the actual mechanical coupling, shown in the sectional view is, for a long time belongs to the known state of the art.
Eine
bevorzugte Ausführungsform
der vorliegenden Erfindung verwendet einen induktiv arbeitenden
Transponder gleichzeitig zur Übertragung
des Signals des Schaltzustandes der Überlastkupplung und zur Messung
des Schaltzustandes. Eine Transponder-Anordnung besteht aus einem
passiven Mobilteil
Das
passive Mobilteil
Das
Sende-Lesegerät
Beim
Eintreten einer Überlast
wird also die Signalübertragung
im Transponder deaktiviert. Dazu sind hiernach mehrere Möglichkeiten
denkbar:
Die Antenne des passiven Mobilteils
The antenna of the passive handset
Die
Antenne des passiven Mobilteils
Ein
Verstimmen der Antenne des passiven Mobilteils des Sende-Lesegeräts kann

einer zweiten Spule
Eine
weitere denkbare Ausführung
der Erfindung besteht darin, einen mechanischen Schalter zur Erkennung
der Überlast
durch Messung der Axialverschiebung des Rings auf der Kupplung zu
verwenden. Sie unterscheidet sich vom Stand der Technik dadurch,
daß der
Schalter auf der Überlastkupplung fest
montiert ist und somit nicht mehr durch Planlauffehler der Überlastkupplung
oder Axialverschiebung der Welle gestört wird. Die Signalübertragung
vom mit der Überlastkupplung
mitrotierenden Schalter zur Maschinensteuerung geschieht berührungslos
mit einer Transpondereinheit. Das Sende-Lesegerät
Der Vorteil der Erfindung liegt in der sicheren Funktion des Sensors unabhängig von Planlauffehlern und Axialverschiebungen der Kupplung, sowie in der vereinfachten Montage beim Einbau der Überlastkupplung in eine Maschine oder Anlage, bei der kein Sensor im Zehntelmillimeterbereich bezüglich des richtigen Schaltpunkts justiert werden muß.Of the Advantage of the invention lies in the safe operation of the sensor independently of run-out errors and axial displacements of the coupling, as well in the simplified assembly when installing the overload clutch in a machine or installation in which no sensor in the tenth of a millimeter range with respect to correct switching point must be adjusted.
