Profile shifted (long addendum and short addendum) gears are being used as the latest small sized reduction gears for automobiles. Therefore, the authors have made experiments on hobbing to find out how to lesson the damage of the cutting edge in the case of profile shifted gears. In the case of the hobbing of profile shifted gears, addendum modinfication has greatly influenced hob damage in same-handed climb hobbing. In the case of reverse-handed conventional hobbing, addendum modification has little influence on hob damage : therefore, the reverse-handed conventional hobbing method is suitable for profile shifted gears.
