摘要： The invention relates to a hammering device (10) for influencing the subsurfaces of workpieces (14) comprising a beating tool (16) for acting on the workpiece (14), a beating mechanism (18) which has a beater (20) for producing a beating pulse on the beating tool (16), and a drive (32) for driving the beating mechanism (18), wherein the beating mechanism (18) has at least a second beater (20) for producing a beating pulse on the beating tool (16). According to the invention, it is intended for the beating mechanism (18) to comprise a drive shaft (30) that extends along a drive axis (A) and a wobble ring (28) for transforming a rotational movement of the drive shaft (30) into a translational movement, and the first beater (20.1) and the second beater (20.2) to be driven by the wobble ring (28).
