SELECTION OF GEOMETRIC PARAMETERS OF GEAR AND GRINDING WHEEL TO ENSURE MAXIMUM GEAR TOOTH PROFILE ACCURACY

ABSTRACT

An analysis of possibilities for the selection of gear and tool geometry parameters is presented to reduce tooth profile errors during the grinding of gears by double tapered wheel (Hofler or Niles method), double wheel generating (Maag method) and by worm wheel techniques (Reishauer method). The selection of gear and tool geometry parameters is based on the analysis of the grid diagram of a gear and a rack. Formulas and graphs are presented for the selection of the pressure angle, module, and addendum of the rack-tool. The experimental results of the grinding of gears confirm the theoretical analysis.
