Drilling and chipping tool

A drilling and/or chipping tool comprising a housing (13, 30, 50) having a central axis, a striking mechanism (8, 28, 69) located within said housing and having a striking direction extending parallel to said central axis, said striking mechanism includes an exciter piston (15, 35, 55) and at least a single part crankshaft (14, 34, 54), a drive motor (9, 31, 51) fixed in said housing and including a drive shaft (10, 32, 52) and a gear unit (11, 29, 49) located between said drive shaft and said striking mechanism (8, 28, 69), said striking mechanism being displaceable parallel to the central axis and abutting said housing (13, 30, 50) via damping elements, wherein the improvement comprises that said gear unit (11, 29, 49) includes a pinion (21, 41, 61) having an axis of rotation extending substantially perpendicularly to the control axis, said gear unit and pinion being fixed within said housing (13, 30, 50), said crankshaft has an axis of rotation extending substantially perpendicularly to the central axis, and an axial displacement compensation element (12, 33, 53) in engagement with and driven by said pinion (21, 41, 61) and in engagement with said striking mechanism for driving said striking mechanism, said axial displacement compensation element providing axial displacement between the axis of said crankshaft and the axis of said pinion.
