    摘要： The carbon brushes (5), arranged in the housing (6) are pressed in a radial direction against the outer surface of a cylindrical collector (4), fixed to the rotor shaft (2) of the motor, by means of a spring force (7). The housing (6) for the carbon brushes (5) may be removed form the motor with little effort, whereby means (11, 12), which protect the rotating bearing (3) of the rotor shaft (2) against the ingress of dirt with one or several bevels (14, 15), are provided on the side thereof facing the housing (6) with the carbon brushes (5), such that the carbon brushes (5) slide along the above on withdrawal of the housing (6) and are thus pressed radially outwards against the spring force (7).

    摘要： The invention relates to a tool holder, in particular for a rotary hammer, having at least a first fixing unit (35) which has at least one force-fitting element (39) and is provided to fix a machining tool along a movement axis (26) by way of a force fit, a second fixing unit (38) which has at least one form-fitting element (40) and is provided, in at least one operating state, together with a form-fitting means (30, 32) of a machining tool (14), to limit freedom of movement (44) of a movement of the machining tool (14) along a movement axis (26), and having a spring unit (78) which is provided to subject the form-fitting element (40) to a clamping force in at least one operating state. It is proposed that, in at least one operating state, the spring unit (78) and the at least one force-fitting element (39) are arranged in a radially overlapping manner at least partially with respect to the movement axis (26).
