Description
Gegenstand der vorliegenden Erfindung ist eine Überlastungskupplung. Diese Kupplung nimmt die angetriebene Welle nur unterhalb eines vorher einstellbaren Höchstlastmomentes mit. Sie unterscheidet sich von sog. Rutschkupplungen dadurch, daß während der Überlastung nicht die gesamte Antriebsleistung, sondern nur ein kleiner Teil derselben in der Kupplung vernichtet wird, während andererseits die Kupplung sofort wieder greift, sobald das Lastmoment unter das eingestellte Höchstlastmoment sinkt.The present invention relates to an overload clutch. This clutch takes the driven shaft only below a previously adjustable one Maximum load torque with. It differs from so-called slip clutches in that that during the overload not the entire drive power, but only one small part of it is destroyed in the clutch, while on the other hand the The clutch engages again as soon as the load torque falls below the set maximum load torque sinks.
Dies wird nach der Erfindung dadurch erreicht, daß eine Profilscheibe mit radial verlaufenden Hügeln und Tälern aus elastischem Werkstoff, z. B. synthetischem Gummi oder Federstahl, auf der einen Kupplungsscheibe angebracht ist, während die andere Kupplungsscheibe Wälzrollen trägt, die radial und vorzugsweise elastisch gelagert sind und in die Täler der Gegenscheibe eingreifen. Die Kupplungskraft kann durch eine einstellbare Feder oder durch einen Elektromagneten geliefert werden, dessen Feld durch Veränderung der Stromstärke regelbar ist.This is achieved according to the invention in that a profile disk with radial hills and valleys made of elastic material, for. B. synthetic Rubber or spring steel on which a clutch disc is attached, while the other clutch disc carries rolling rollers that are radial and preferably elastic are stored and engage in the valleys of the counter disc. The clutch force can be supplied by an adjustable spring or by an electromagnet, whose field can be regulated by changing the current strength.
In der Zeichnung sind zwei Ausführungsbeispiele dargestellt. Die Überlastungskupplung besteht aus dem treibenden Teil. a, auf dem eine Profilscheibe b befestigt ist. Das Profil besteht aus Tälern und Hügeln, die radial verlaufen. In den Tälern liegen Mitnehmerwälzrollen d, die auf der getriebenen Scheitre c drehbar gelagert sind. In der Abb. 3 sind diese Teile schematisch dargestellt.Two exemplary embodiments are shown in the drawing. The overload clutch consists of the driving part. a, on which a profile disk b is attached. The profile consists of valleys and hills that run radially. In the valleys are driving rollers d, which are rotatably mounted on the driven log c. In Fig. 3 these parts are shown schematically.
Der Kraftschluß zwischen Profilscheibe b und den Wälzrollend ist elastisch ausgebildet. Das kann dadurch geschehen, daß die Profilscheibe b aus elastischem Werkstoff, z. B. aus syntahetischem Gummi, hergestellt wird, oder dadurch, daß das Profil durch eine elastische Stahlfeder gebildet wird, oder dadurch, daß die Wälzrollen durch Druck-oder Blattfedern elastisch gelagert werden oder durch eine Kombination der vorgenanntes Mittel.The frictional connection between the profile disk b and the rolling rollers is elastic educated. This can be done in that the profile disk b is made of elastic Material, e.g. B. made of synthetic rubber, or in that the Profile is formed by an elastic steel spring, or by the fact that the rolling rollers be mounted elastically by compression or leaf springs or by a combination the aforementioned means.
Durch ein Kuppelelement e, in Ab l>. i eine Druckfeder, in Abb. 2 ein Elektromagnet, werden die Kupplungshälften a und c aneinandergedrückt bzw. -gezogen. Je nach der Einstellung der Druck- bzw. Zugkraft kann ein ganz bestimm?es maximales Übertragungsdrehmoment eingestellt werden. Bei Überschreitung dieses Drehmomentes gleitet eine Scheibe auf der anderen.By a coupling element e, in Ab l>. i a compression spring, in Fig. 2 an electromagnet, the coupling halves a and c are pressed or pulled together. Depending on the setting of the compressive or tensile force, there can be a very specific maximum Transmission torque can be adjusted. If this torque is exceeded one disk slides on the other.
