ADJUSTABLE GEAR SHAPER Russian patent published in 2006 - IPC B23F21/10 

FIELD: machine engineering, manufacture of gear shaping tools.

SUBSTANCE: gear shaper with restored thickness of tooth includes two parts coaxially mounted with possibility of rotation. Two sectional washers with inner diameter equal to mounting diameter of parts are coaxially arranged between said parts. Said washers are stuck to new non-worn portions at matching axes of teeth. One washer has locking eccentric pin with dial rolled-in to it with possibility of rotation; it enters radial groove of other washer. Said pin is designed for relative rotation of parts after each regrinding by angle set with use of dial and determined according to given formula.

EFFECT: enhanced stability of parameters of profiles of shaped gear wheels, improved accuracy of mounting gear shaper, increased strength and useful life period of it due to separate cutting and gradual adjusting of mutual rotation angle of gear shaper parts.
