Spur gears of 10 diametral pitch were induction hardened with various heating conditions, and distortions, generated by thermal changes only, were shown in the 1st report. In the 2nd report, results of measurements of distortions, caused by quenching transformations as well as by thermal changes, were described, Materials of gears were 0.45%C steel. Items of measurements were as follows : outer diameter, inner diameter, width, whole depth, radius of root circle, thickness of tooth, undulation of tooth trace, undulation of end surface of gear, tooth profile, eccentricity, out of roundness, normal pitch and error measured with Carl Mahr type meshing test machine. Further, the influences of key way on eccentricity, out of roundness and normal pitch were also measured.
