Abstract

Die Erfindung betrifft eine Fräsmeißelanordnung (100) für eine Bodenfräse, beispielsweise eine Kaltfräse, oder einen Bergbaubohrer, umfassend:
- einen Meißelhalter (10), der an einer Fräswalze befestigbar oder befestigt ist,
- einen am Meißelhalter befestigten Fräsmeißel (20), der mit seinem Fräsmeißelschaft in einer Meißelhalterbohrung des Meißelhalters (10) einsitzt und sich um seine Längsachse drehen kann, und
- eine Verschleißscheibe (30), die verdrehsicher zwischen einer Anschlagfläche des Meißelhalters (10) und dem Fräsmeißelkopf des Fräsmeißels (20) angeordnet ist,

wobei vorgesehen ist, dass die Verdrehsicherung zwischen der Verschleißscheibe (30) und dem Meißelhalter (10) durch wenigstens eine am Außenumfang der Verschleißscheibe (30) ausgebildete Nut (31) und eine am Meißelhalter (10) ausgebildete und in diese Nut (31) eingreifende Führung (11) bewerkstelligt ist.
Die Erfindung betrifft ferner eine Verschleißscheibe (30) zur Verwendung in einer solchen Fräsmeißelanordnung (100), sowie einen Fräsmeißel (20) mit einer solchen vormontierten Verschleißscheibe (30).
