Abstract

Ein elektrisches Handwerkzeuggerät (2) weist ein Hauptgehäuse (4) in Schalenbauweise und eine an einem werkzeugseitigen Ende (18) aus dem Hauptgehäuse (4) austretende Werkzeugspindel (14) auf, die über einen Motor (12) und ein Getriebe (16), die im Hauptgehäuse (4) untergebracht sind, um eine Arbeitsachse (A) herum rotatorisch antreibbar sowie von einem Ratschenschlagwerk (38) mit impulsartigen Axialbewegungen beaufschlagbar ist, das einen gehäusefesten Zahnkranz (43) aufweist, der mit einem sich am Hauptgehäuse (4) abstützenden Stützkörper (44) verbunden ist und der mit einem mit der Werkzeugspindel (14) drehgekoppelten beweglichen Zahnkranz (41) zusammen wirkt, wobei sich der Stützkörper (44) über Abstützmittel (58) in eine von dem werkzeugseitigen Ende (18) abgewandte Richtung abstützt. Es ist vorgesehen, dass die Abstützmittel (58) an einer Innenfläche (56) einer Aussenschale (34) des Hauptgehäuses (4) umlaufend ausgebildet sind und der Stützkörper (44) direkt an den Abstützmitteln (58) anliegt.

An electric hand tool device (2) has a main housing (4) in a shell construction and a tool spindle (14) emerging from the main housing (4) at a tool-side end (18), which has a motor (12) and a gear (16), which are housed in the main housing (4), rotatably driven about a working axis (A) and acted upon by a ratchet impactor (38) with pulse-like axial movements, which has a housing-fixed sprocket (43) with a on the main housing (4) supporting Support body (44) is connected and cooperates with a rotatably coupled to the tool spindle (14) movable sprocket (41), wherein the support body (44) via support means (58) in a direction away from the tool-side end (18) direction is supported. It is provided that the support means (58) on an inner surface (56) of an outer shell (34) of the main housing (4) are formed circumferentially and the support body (44) directly against the support means (58).
