The sprocket of scraper conveyor used in Shiyaodan Mining Co. , Ltd. was taken as the research object, the factors that might affect the sprocket fatigue failure were analyzed. SolidWorks was used to create the model of scraper sprocket chain link. ABAQUS software was used to conduct the finite element simul ation of sprocket chain link stress concentration area. In order to study the importance of different factors affecting the fatigue failure of scraper sprocket, a"four factors, three levels"orthogonal test was car-ried out, and the range and variance analysis were carried out on the test results. The results show that the arc radius of the tooth root is the key factor affecting the sprocket fatigue failure, while the influences of arc radius of the tooth shape, the thickness of the short tooth and the arc radius of the chain pit on the fatigue failure of the sprocket are relatively smaller.
