Abstract:
Hammer brush holder arrangement with tilt-preventing mechanism, comprising:a motor stator part; a hammer brush holder having a brush and having a pivotal bearing on the motor stator part; a projecting securing pin on at least one of the hammer brush holder and the motor stator part, which, in an operational position of the brush holder and the motor stator part, engages into a corresponding securing notch of at least the other of the motor stator part and the hammer brush holder, so as to at least limit tilting of the hammer brush holder in response to a force that is at least mostly perpendicular to a pivotal motion about the pivotal bearing; cupped bearing receptacles on at least one of the hammer brush holder on an end of the hammer brush holder facing away from the brush, and the motor stator part, wherein the cupped bearing receptacles are located axially on either side of the securing pin, and wherein the cupped bearing receptacles are pivotally mounted onto at least one corresponding knife-edged bearing of at least the other of the motor stator part and the hammer brush holder; and a form-fitting, position fixating, tongue-shaped, axial securing stop associated with each corresponding knife-edged bearing.
