A Study on the Effect of Heat-treatment on the Fatigue Strength of Spur Gears

기어의 피로강도에 미치는 열처리효과에 관한 연구

This study deals with effects of heat-treatment on the bending fatigue of spur gears. The test gears are heat-treated by two different treatments. After carburization, one group of the test gears is quenched directly, while another group is furnace cooled, reheated then quenched. The fatigue test at a constant stress amplitude is performed by using an electrohydraulic serve-controlled pulsating tester. The S-N curves are obtained and illustrated.
