Abstract

Die Erfindung betrifft einen Bohrhammer mit einem Luftpolsterschlagwerk, bei welchem eine Erregerhülse (24), die einen das Luftpolster aufnehmenden Raum (26) bildet und in der ein Schlagkolben (28) hin- und herbewegbar ist, konzentrisch zur Bohrwerkzeugachse (10) angeordnet ist, und mit einer die Erregerhülse (24) in Richtung der Bohrwerkzeugachse (10) hin- und herbewegenden Taumeltriebvorrichtung (34), deren die Taumelscheibe (42) antreibendes Rotationselement (36) auf einer parallel zur Bohrwerkzeugachse (10) jedoch in einem Abstand neben dieser rotierend antreibbar vorgesehen ist; um die Laufunruhe des Bohrhammers zu reduzieren, ist auf der Erregerhülse (24) vorgesehen, dass die diametral gegenüberliegenden Seite der Taumelscheibe (42) ein Gewichtskörper (50) zwangsgeführt linear und parallel zur Bohrwerkzeugachse (10) unter der Wirkung der Taumelscheibe (42) hin- und herverschiebbar vorgesehen ist.
