Abstract

The two axially movable coupling segments (1, 2) are joined with a radial arranged shear pin (3), guided by the bearing bush (4) and kept in position by a securing ring (5). The engaging or releasing of the coupling is performed with the bearing. When a set torque limit is exceeded the shear pin (3) breaks at the predetermined breaking point, causing the coupling parts (1, 2) to move separately resulting in an interruption of the connection between drive shaft (7) and output shaft (6).

Description

Sicherheitskupplung mit integriertem ÜberlastschutzSafety clutch with integrated overload protection

Die Erfindung betrifft einen Überlastschutz mittels Scherbolzen, der in eine
vorhandene Sicherheitskupplung integrierbar ist.
Bekannt ist eine Sicherheitskupplung mit Überlastschutz, bei der der
Überlastschutz getrennt von der eigentlichen Kupplung durch eine Sollbruchstelle in der Abtriebswelle (6) verwirklicht ist. Dies hat den Nachteil, dass zum Einen die komplette Kupplung zum Wechseln der Abtriebswelle demontiert werden muss und dass zum Anderen die relativ teure Abtriebswelle bei Ansprechen der Überlastfunktion zerstört wird.The invention relates to an overload protection by means of a shear bolt, which is integrated in a
existing safety coupling can be integrated.
A safety clutch with overload protection is known, in which the
Overload protection is implemented separately from the actual clutch by means of a predetermined breaking point in the output shaft (6). This has the disadvantage that, on the one hand, the entire clutch has to be dismantled to change the output shaft and, on the other hand, that the relatively expensive output shaft is destroyed when the overload function is activated.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Überlasteinrichtung in die vorhandene Sicherheitskupplung so zu integrieren, dass sie unter Beibehaltung der Sicherheitsfunktion der Kupplung mit kostengünstigen Schutzelementen
ausgestattet ist, die ein einfaches Austauschen ermöglichen.The invention is therefore based on the object of integrating an overload device into the existing safety coupling in such a way that it can be equipped with cost-effective protective elements while maintaining the safety function of the coupling.
which allow for easy replacement.
