Abstract (en)
The portable electric hammer drill (1) has a hammer component group (2) which is separated accurately from a grip point (P) at the tool housing (3) by a coil spring (4), to disengage vibrations. The hammer group is also mounted on at least two axially displaced joint arms (5a,5b) with axially defined movements. The joint arms have a bending distortion, and are fixed to the housing without allowing a sliding movement. At least one arm has a center section with a bending stiffness, and two film joints (7) at the ends with an elastic distortion.
Abstract (de)
Eine Schlagwerksbaugruppe (2) einer zumindest teilweise axial schlagenden Handwerkzeugmaschine (1) ist über eine Feder (4) gegenüber genau einem Angriffspunkt (P) im Gehäuse (3) schwingungsentkoppelt sowie über ein, aus zumindest zwei axial beabstandeten und axial begrenzt beweglichen Gelenkarmen (5a, 5b) bestehendes, Axialführungsmittel gelagert. Die Gelenkarme (5a, 5b) sind biegeschlaff deformierbar ausgebildet und mit dem Gehäuse (3) gleitbewegungsfrei verbunden. <IMAGE>
