Abstract

Die Erfindung betrifft ein motorisch angetriebenes Werkzeuggerät, insbesondere Winkelschleifgerät (2), mit einem die elektromotorischen Komponenten aufnehmenden Maschinengehäuseteil und einem die Getriebekomponenten aufnehmendem Getriebegehäuseteil, mit einer Motorwelle (6) und einer Werkzeugspindel (12), wobei ein rotierend antreibbares Werkzeug (16) von der Werkzeugspindel (12) antreibbar ist, und mit einer das rotierend antreibbare Werkzeug (16) teilweise umfangenden Schutzhaube (22), die am Werkzeuggerät werkzeuglos anbringbar und abnehmbar und gegenüber dem Werkzeuggerät in verschiedene Drehstellungen bringbar ist, wobei die Schutzhaube (22) einen im wesentlichen in der Ebene des Werkzeugs (16) erstreckten scheibenförmigen Teil (28) und radial außen einen den Rand des Werkzeugs (16) umfangenden Randteil(30) aufweist; um den axialen Bauraum zu reduzieren wird vorgeschlagen, das Werkzeuggerät so auszubilden, dass der scheibenförmige Teil (28) der Schutzhaube (22) eine randoffene Ausnehmung (26) aufweist und im wesentlichen in seiner Ebene in die bestimmungsgemäße Montageposition an einem Halsabschnitt (24) des Werkzeuggeräts aufschiebbar ist, in der der Halsabschnitt (24) in der randoffenen Ausnehmung (26) des scheibenförmigen Teils (28) aufgenommen ist, und dass der Halsabschnitt (24) ein in seiner Umfangsrichtung durchgehend oder unterbrochen erstrecktes, insbesondere nutförmiges Aufnahmemittel (40) für den die randoffene Ausnehmung (26) begrenzenden Randabschnitt (42) des scheibenförmigen Teils (28) der Schutzhaube (22) aufweist, so dass der Randabschnitt (42) des scheibenförmigen Teils (28) beim Aufschieben auf den Halsabschnitt (24) in das Aufnahmemittel (40) eingreift und damit die Schutzhaube (22) in axialer Richtung formschlüssig an dem Halsabschnitt (24) gehalten ist, und dass die Schutzhaube (22) in ihrer Montageposition durch ein Belastungs- oder Sperrmittel (46) in Umfangsrichtung (36) und in radialer Richtung gegen Lösen oder Verdrehen gestützt ist.
