Abstract

Eine zumindest teilweise schlagende Handwerkzeugmaschine mit einem pneumatischen Schlagwerk und einem durch eine Luftfeder angetriebenen Flugkolben, welcher auf einen in einem Führungsrohr (6) geführten sowie über zwei Axialanschläge (9a,9b) begrenzt axial beweglichen Döpper (8) schlägt, welcher einen Aussenradialbund (11) ausbildet, der von einem koaxial aussen angeordneten Stossring (12) axial beidseitig mit je einer Innenradialflanke (14) radial umfasst sowie zum Aussenradialbund (11) axial begrenzt frei beweglich ist, wobei der Aussendurchmesser des Stossrings (12) kleiner als der führende Innendurchmesser des Führungsrohres (6) ist und dass das Massenverhältnis des Stossrings (12) zum Döpper (8) zumindest 0,25 ist.
