Tooth flank feature analysis and study on grinding method of full edge gear honer

Tooth flank equation of full edge gear honer was deduced according to the principle of gear engagement. Some basic tooth flank features of full edge gear honer were obtained through calculating tooth flank coordinates, involute fitting to arbitrary end cross-section and calculating modification relative to involute helicoid. The results showed that profile of full edge gear honer almost coincided with involute helicoid in midship section, but cross-section profile from midship section to two ends showed that base circle changed gradually, axial shape is concave and anti-drum, and tooth flank of full edge gear honer could be regarded as involute helicoid which was modified. Grinding method of full edge gear honer was determined according these features, that is, tooth flank of imaginary rack was calculated through conjugate tooth flank of entir cutting honer, then tooth flank of imaginary rack is approached by cone grinding wheel, then the dressing parameters of grinding wheel and the adjusting parameters of machine tool were calculated, and the results showed that this method was feasible^[1].
