Abstract

Es wird ein Rotor (1) einer Zerkleinerungsvorrichtung von Holz, Abfällen oder sonstigem Material aus zwischen benachbarten Rotorscheiben (2) an zur Rotorwelle (8) koaxialen Schlägerstangen (4) schwingend und/ oder feststehend angeordneten Werkzeugen (19) sowie weiteren Schutzelementen zur Verfügung gestellt, der eine robuste Lagerung von Werkzeugen (19) und Schutzelementen gewährleistet und zudem universell und wirtschaftlich an die geforderte Güte eines Hackgutes angepasst werden kann und eine gesteigerte Laufruhe sowie eine erhöhte Betriebssicherheit aufweist, was dadurch erzielt wird, dass ein Schutzelement aus einem Grundköper (5) mit mindestens zwei Verbindungseinrichtungen zur Befestigung am Rotor (1) besteht, einem ersten Lagerauge (9) zur Aufnahme einer Schlägerstange (4) und einer zweiten Kupplungsvorrichtung mit einer im montierten Zustand des Grundkörpers (5) mit den Rotorscheiben (2) gegenseitig in Eingriff befindlichen Verriegelung.
