A Study on Crack Initiation Measurement of Carburized Gear Tooth by Acoustic Emission
침탄치차의 AE법에 의한 크랙발생의 계측에 관한 연구
Abstract
Acoustic emission technique is applied to the fatigue crack initiation in a carburized gear tooth. Acoustic emission test performed on carburized gear and three-point bending test equal to carburized gear hardness. The marked acoustic emission are detected at the early stage of crack initiation measured by a crack gauge and the final stage just before the tooth failure. The estimated acoustic emission energy rate are characteristic of the measured acoustic emission.
