ABSTRACT:
To correct the tooth profile error of a ground gear, the wheel angle of a threaded grinding wheel is modified by dressing the threaded grinding wheel by a dressing device. To correct the helix form deviation of a ground gear, namely, to modify the helix angle of the gear, synchronization between the moving motion in the Z-direction of the threaded grinding wheel and the rotary motion of a table for installation of the gear is adjusted. When the helix form deviation is corrected by adjustment of the synchronization, a tooth profile change inevitably occurs. In consideration of the tooth profile change, correction of the tooth profile error by dressing is made.
