In the present report, the possibility of the roll-finishing of a quenched gear was discussed. In order to reveal the effects of the quenching of a gear on a roll-finished tooth form, computer simulations were carried out. In the simulation, an increase of flank hardness by quenching was regarded as an increase of contact compliance of the tooth flank, i. e. an increase in resistance to contact deformation. The simulation result showed that an increase in contact compliance reduced the amount of rounding down at both tooth edges on a roll-finished tooth trace. Then, experiments of the roll-finishing of a quenched work-gear were carried out. In these experiments, the roll finishing of work-gears with flank hardness H_<RC> = 40 induced a fairly good tooth form, as in the simulation results. However, when the flank hardness of the work gear was H_<RC> = 55, a strong interference between the tooth tip of the die-wheel and the tooth root of the work-gear was induced and roll-finishing did not proceed.
