Striper for machining rod/tube shaped workpieces, has relative motion unit with gear comprising cover and holder drive pinions, and control unit controlling axial displacement of gear shaft relative to feed cover and/or workpiece holder

摘要

The striper has a feeding unit for converting relative motion between a workpiece holder (3) and a feed cover (4) to a feed motion of workpieces (7). The relative motion is rotated concentrically relative to a rotation axis of the holder. A relative motion unit has a gear with a cover drive pinion (19) and holder drive pinion (18) including inclined gear teeth and arranged at a gear shaft (17). The pinions interfere to gear rims (15, 14) of the cover and holder, respectively. A control unit controls axial displacement of the gear shaft relative to the cover and/or to the holder.
