Power-driven offset screw driver has reduction gear with reaction part to accommodate reaction momentum relative to spindle

摘要

The screw driver housing (11) contains drive (32), reduction gear (38), spindle (40), and offset head (20). The reduction gear has a reaction part to accommodate a reaction momentum relative to the spindle. The part is connected non-turnable to the offset head housing (19), and coupled to the drive via an adjusting unit (58). A torque limitation coupling (50) has a first part fastened non-turnable to the offset head housing, and a second part similarly fastened to the reaction part of the reduction gear.
