PatentANSPRÜCHE:Patent claims: 1. Sicherheitsvorrichtung zur Drehzahlüberwachung einer Welle, bestehend aus einem in der Welle eingebauten Bolzen, dessen Schwerpunkt außerhalb der Wellenachse liegt und der bei Überschreitung einer einstellbaren Drehzahl der Welle durch die Fliehkraft entgegen der ihn in seiner Lage haltenden Kraft verschoben wird, so daß durch einen an ihm befindlichen Anschlag eine Absperrvorrichtung betätigt wird, dadurch gekennzeichnet, daß die den Bolzen haltende Kraft durch einen Magnet (4) erzeugt wird.1. Safety device for monitoring the speed of a shaft, consisting of one in the Shaft built-in bolt whose center of gravity lies outside the shaft axis and which is exceeded when it is exceeded an adjustable speed of the shaft by the centrifugal force against him in his Position holding force is shifted, so that a shut-off device by a stop located on it is actuated, characterized in that the force holding the bolt is generated by a magnet (4). 2. Sicherheitsvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß als Magnet ein hufeisenförmiger permanenter Magnet benutzt wird, der magnetisch isoliert auf der Welle (1) angebracht ist.2. Safety device according to claim 1, characterized in that a horseshoe-shaped magnet permanent magnet is used, which is magnetically isolated and attached to the shaft (1) is. 3. Sicherheitsvorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß der Bolzenschaft (8) aus nichtmagnetischem Material besteht, während der die Enden des Magnets (4) verbindende Bolzenkopf (9) aus magnetisch leitendem Material, z. B. Eisen, besteht.3. Safety device according to claim 2, characterized in that the bolt shank (8) consists of non-magnetic material, while the connecting the ends of the magnet (4) Bolt head (9) made of magnetically conductive material, e.g. B. iron. 4. Sicherheitsvorrichtung nach Anspruch 3, dadurch gekennzeichnet, daß in dem Bolzenschaft (8) eine Schraube (11) zum Einstellen seiner Schwerpunktlage angeordnet ist.4. Safety device according to claim 3, characterized in that in the bolt shank (8) a screw (11) is arranged for adjusting its center of gravity. Hierzu 1 Blatt Zeichnungen1 sheet of drawings
