Table 2

Strength and ductility of three carburized gear-pair models studied.

Carburized gear teeth	Gear-pair strength	Strength ratio	Gear-pair ductility	Ductility ratio
	(N.m)	(based on EH model)	(×100 kJ/mm^3)	(based on EH model)
EH model	4322	1	814	1
IH model	4609	1.066	1195	1.468
HH model	4480	1.037	912	1.120
