Rammer for drilling and/or chisel hammer, has beat driving apparatus for translating rotating movement of intermediate shaft into translatory motion for driving rackets, where beat driving apparatus comprises non-circular toothed gearing
The rammer (10a) has rackets (14a), and a beat driving apparatus (16a) for translating rotating movement of an intermediate shaft (28a) into translatory motion for driving the rackets. The beat driving apparatus comprises a non-circular toothed gearing (18a), which acts on the rackets in an operating mode, where the non-circular toothed gearing comprises pivotally driven eccentric toothed segments and translationally driven eccentric racks (22a) in the operating mode. The non-circular toothed gearing comprises gear elements.
