Abstract
(DE)
Die Erfindung betrifft ein Werkzeug für eine Strassenfräs-, Schrämm-, Bergbaumaschine oder dgl. mit einem Meissel (10), der einen Meisselkopf (11) und einen Messelschaft (15) aufweist, wobei der Meisselschaft (15) in einer Aufnahme (23) eines Meisselhalters (20) drehbar aufgenommen ist, wobei ein Verschleissschutzelement (30) mit einem Durchbruch (35) auf den Meisselschaft (15) aufgesteckt ist und wobei der Meisselkopf (11) unter Zwischenlage des Verschleissschutzelementes (30) an dem Meisselhalter (20) anliegt. Um das Verschleissschutzverhalten eines solchen Werkzeuges zuverbessern, ist es erfindungsgemäss vorgesehen, dass das Verschleissschutzelement (30) ein oder mehrere Federelemente (32) aufweist, die den Meisselkopf (11) gegenüber dem Meisselhalter (20) federelastisch abstützen.
(EN)
The invention relates to a tool for a street milling, coal-cutting, mining machine or the like which comprises a chisel (10) with a chisel head (11) and a chisel stem (15). Said chisel stem (15) is rotatably mounted in a receiver (23) of a chisel holder (20). A perforated (35) wearing protection element (30) is mounted on the chisel stem (15), and the chisel head (11) sits closely on the chisel holder (20) while embracing the interposed wearing protection element (30). The aim of the invention is to improve the wearing protection behavior of such a tool. To this end, the inventive wearing protection element (30) comprises one or more spring elements (32) that elastically support the chisel head (11) vis-à-vis the chisel holder (20).
(FR)
L'invention concerne un outil pour une fraiseuse, haveuse, machine minière ou similaire, comportant un trépan qui présente une tête et une tige logée de manière à pouvoir tourner dans un logement d'un porte-trépan. Un élément de protection contre l'usure comportant une ouverture est placé sur la tige du trépan. La tête du trépan prend appui sur le porte-trépan, l'élément de protection contre l'usure étant intercalé entre les deux. L'invention vise à améliorer les propriétés anti-usure d'un tel outil. A cet effet, l'élément de protection contre l'usure présente un ou plusieurs éléments ressorts qui soutiennent la tête du trépan de manière élastique par rapport au porte-trépan.
