Distortions and Residual Stresses of Gears Caused by Hardening : 4th Report, Case-Hardening of Gears
Bulletin of JSME, 1979 Distortions of case-hardened gears were calculated using the method introduced by the authors, and the results were compared with experimental ones. The results obtained in this paper are summarized as follows. (1) For case-hardening, gear distortions can be calculated tolerably well from the estimation of quenched structure. (2) In this investigation,
