Study on Tooth Interior Fatigue Fracture Failure of Wind Turbine Gears
Metals, 2020 Gear contact fatigue has becoming a bottleneck restricting the safety and reliability of wind turbine transmission systems. Tooth interior fatigue fracture (TIFF) failure is commonly observed in case-hardened wind turbine gears.

Effects of Gear-Side Case-Hardening on Residual Stress of Case-Hardened Gears.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2001 This paper presents a study on effects of gear-side case-hardening on residual stresses of case-hardened gears. The carbon content of each element of the FEM models due to carburizing was computed on the basis of the relation between carburizing condition and carbon content distribution. A heat conduction analysis and an elastic-plastic stress analysis

Influence of Hardenability on Gear Distortions Caused by Hardening
Bulletin of JSME, 1983 The kinds of materials have different effects on gear distortions caused by hardening, even if heat-treatments of the raw material and gear are the same. In this experiment, the test gears which were made of steel materials containing different amounts of some chemical compositions in two kinds of steel were case-hardened.

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,
