METHOD FOR STABILIZING PARAMETERS OF GEAR WHEEL TEETH CUT BY MEANS OF BUILTUP ADJUSTABLE GEAR SHAPER Russian patent published in 2005 - IPC

FIELD: manufacturing processes in machine engineering, manufacture of gear cutting tools and gear wheels.

SUBSTANCE: method is realized by means of gear shaper having housing with grooves and cutting teeth arranged in said grooves. When teeth are dulled their front faces are subjected to regrinding. In order to stabilize parameters of cut gear wheels regardless of wear degree of gear shaper, constant diameter of teeth apexes is provided due to their radial protruding after regrinding. Grooves in housing end of gear shaper are radial ones and they have mutually parallel lateral sides. Teeth are secured to bottom of groove by means of screws arranged in axial grooves of housing. Gear shaper is provided with separator whose surfaces inclined relative to lengthwise axis are engaged with reciprocal inclined surfaces of teeth and with nut-tie rod screwed in central opening of gear shaper and holding separator with use of washer secured to nut-tie rod by means of screws. Teeth are adjusted and aligned due to releasing fastening screws, screwing nut-tie rod into housing of gear shaper and tightening fastening screws.

EFFECT: stabilized parameters of gear wheels regardless of wear degree of gear shaper.
