소결치차의 성능향상과 신뢰성이 높은 소결치차 설계에 관한 연구
A Study on the Improvement and Reliable Design in Sintered Spur Gear
초록
It is very important to have exact informations on the properties and characteristics of the sintered steel as a new material of machine elements. The bending fatigue tests are performed for sintered steel bend specimens and spur gears, which are notched by using a slicing blade. The fatigue test at a constant stress amplitude is performed by using an electrohydraulic servo-controlled pulsating tester Consequently, the S-N curves are obtained and the fatigue strength. is compared with flaw depth. Accordingly, this study presents the fatigue strength of sintered spur gears, the critical notch depth of sintered steel and the effects of flaw depth on the bending fatigue strength. The enhancement of fatigue strength due to carburized treatment is clarified.
