Abstract

Ein Elektrohandwerkzeuggerät mit einem, ein elektropneumatisches Schlagwerk (1) antreibendes, Kurbelgetriebe mit einer in zumindest einem Radialwälzlager (6, 6') gelagerten Welle (3, 14) bildet innerhalb eines axialen Lagerbereiches (2) in einem radialen Teilbereich der Welle (3, 14) zumindest ein Lagerungsmittel als Wälzlagering (5, 5', 18) des Radialwälzlagers (6, 6') aus, wobei eine radiale Ineinanderverschachtelung des Lagerungsmittels der Welle (3, 14) mit zumindest einem Zusatzmittel (8, 11, 15) für eine Zusatzfunktion ausgebildet wird.

Figure 00000001
An electric hand tool device with a crank mechanism driving an electropneumatic hammer mechanism (1) with a shaft (3, 14) mounted in at least one radial roller bearing (6, 6 ') forms within an axial bearing area (2) in a radial partial area of the shaft (3, 14) at least one bearing means as a roller bearing ring (5, 5 ', 18) of the radial roller bearing (6, 6'), with a radial nesting of the bearing means of the shaft (3, 14) with at least one additional means (8, 11, 15) for an additional function is formed.
