GEAR SHAPING METHOD WITH THE USE OF ADJUSTABLE COMPLETE SHAPING CUTTER Russian patent published in 2005 - IPC

FIELD: mechanical engineering, particularly toothed gear wheel production.

SUBSTANCE: method for shaping toothed gear wheels by running-in process in which pair of toothed gear wheels are brought into engagement involves imparting rotation to the first member, namely wheel to be processed, imparting rotation and reciprocation to the second member, namely round composite complete shaping cutter composed of coaxial upper and lower parts so that the parts may perform mutual rotation through an angle, may be demounted and separately regrinded to realize sharing scheme of cutting layers. The parts are mutually rotated after each regrinding operation through α_m angle determined from a given formula. α_m is defined by limb of eccentric fixing pin arranged between above parts. Two sectional washers are installed between the parts. Inner diameter of each washer is equal to seating diameter of each part. Above eccentric fixing pin is embedded in one part. Fixing pin is inserted into radial slot of another washer. Washers are glued to new, non-worn parts when teeth axes coincide one with another.

EFFECT: increased efficiency and stability of wheel parameters.
