Fine finishing process for toothed gear wheels uses continuous rolling grinding process for finishing teeth, bore and possible end sides in one clamping action

摘要

Where the gear wheels are hardened and have a cylindrical bore (8) the teeth (7) and simultaneously the bore and possibly an end face where required are finished in a continuously operating rolling grinding process which is undertaken using a cylindrical grinding worm. Independent claim describes device where the gear wheel (6) is clamped between two end faces and centred on a follower (9) and/or counter holder (10) which has a through bore coaxial with its rotary axis through which an internal finishing tool (11) is guided for finishing the bore (8) of the gear wheel (6) and the grinding worm is clamped by a grinding spindle for finishing the teeth.
