Abstract
Description
Die Erfindung betrifft eine Kupplung mit einem ersten, als Wellenende ausgebildeten Kupplungsteil, einem zweiten, als Wellenende ausgebildeten Kupplungsteil und einem elastischen Verbindungsteil, wobei erstes und zweites Wellenende und das Verbindungsstück um eine gemeinsame Drehachse drehbar sind. The invention relates to a coupling with a first, designed as a shaft end coupling part, a second, designed as a shaft end coupling part and an elastic connecting part, wherein the first and second shaft end and the connecting piece are rotatable about a common axis of rotation.
Bei Kupplungen zwischen zwei Wellenenden zur Übertragung von Drehmoment ist es häufig nötig, das zu übertragende Moment zu begrenzen, um Schäden von weiteren Bauteilen abzuwenden. Dazu sind Rutschkupplungen im Einsatz. In the case of couplings between two shaft ends for transmitting torque, it is often necessary to limit the moment to be transmitted in order to prevent damage to other components. These are friction clutches in use.
Eine Bauform der genannten Kupplungen bedient sich eines elastischen Schlauchstückes zur Verbindung der Wellenenden. Das Schlauchstück weist eine Innenverzahnung auf, wobei die Zähne verschiedene Profile aufweisen können. Die Hauptachse der Zähne ist dabei axial ausgerichtet und korrespondiert mit jeweils in den Schlauch einsteckbaren Wellenenden, die ebenfalls eine mit der Verzahnung des Schlauchstückes korrespondierende Verzahnung aufweisen. Die
Die Begrenzung des übertragbaren Drehmomentes erfolgt dabei einerseits über die Verdrehfestigkeit des Schlauchstückes, andererseits über die Scherfestigkeit der in dem Schlauchstück angeordneten Zähne. Steigt das Drehmoment über den zulässigen Wert, ist dies meist mit der Zerstörung des Schlauchstückes verbunden. The limitation of the transmittable torque takes place on the one hand on the torsional strength of the hose piece, on the other hand on the shear strength of the arranged in the hose piece teeth. If the torque exceeds the permissible value, this is usually associated with the destruction of the hose section.
Der Erfindung liegt die Aufgabe zugrunde, eine Rutschkupplung der eingangs geschilderten Art zu schaffen, die kostengünstig ist, bei einer Überschreitung des zulässigen Drehmomentes durchrutscht und kurzfristige Überlastungen ohne Zerstörungen übersteht. The invention has for its object to provide a slip clutch of the type described, which is inexpensive, slipping when exceeding the allowable torque and short-term overloads survives without destruction.
Diese Aufgabe wird dadurch gelöst, dass das elastische Verbindungsteil der Kupplung ein nach Innen auf die gemeinsame Drehachse gerichtetes Keilrippenprofil mit mehreren Stegen und Tälern aufweist, bei dem das Keilrippenprofil im wesentlichen in Drehrichtung der Kupplung, also orthogonal zur Drehachse der Kupplung, angeordnet ist und die Wellenenden jeweils eine mit dem Keilrippenprofil des Verbindungsteils korrespondierende Verzahnung mit Keilnuten aufweisen, wobei das Verbindungsteil derart ausgebildet ist, dass es in montiertem Zustand tangential gedehnt ist und die Stege des Keilrippenprofiles des Verbindungsteils in die Keilnuten der Wellenenden eingreifen. This object is achieved in that the elastic connecting part of the coupling has an inwardly directed to the common axis of rotation V-rib profile with a plurality of webs and valleys, in which the V-rib profile is arranged substantially in the direction of rotation of the clutch, that is orthogonal to the axis of rotation of the clutch and the Each shaft ends have a corresponding with the V-rib profile of the connecting part toothing with splines, wherein the connecting part is designed such that it is stretched tangentially in the assembled state and engage the webs of the V-rib profile of the connecting part in the splines of the shaft ends.
Durch diese Anordnung kommt es zwischen dem Keilrippenprofil des Verbindungstücks und der Verzahnung der Wellenenden zu einem Reibschluss. Durch diesen Reibschluss ist über das Verbindungsteil
In einer Weiterbildung der Erfindung weist das Verbindungsteil in Drehrichtung verlaufende, in einer elastomeren Matrix eingebettete elastische Zugstränge auf. In one development of the invention, the connecting part has an elastic tensile cords running in the direction of rotation and embedded in an elastomeric matrix.
Die tangentiale Spannung des Verbindungsteils in montiertem Zustand ist durch Verwendung zusätzlicher Zugstränge erhöhbar, so dass größere Momente übertragbar sind. The tangential tension of the connecting part in the assembled state can be increased by using additional tension cords, so that larger moments can be transmitted.
Anhand der Zeichnung wird nachstehend ein Ausführungsbeispiel der Erfindung näher erläutert. Reference to the drawings, an embodiment of the invention will be explained in more detail below.
