The faults include the fracture of saddle support mat, the breakdowns of saddle support bolt and pin spindle. Based on the analysis on the fracture and surface, the fault causes are analyzed, for the conclusions of the normal fatigue fracture, as well as the deficient gear hardness, higher contact stress of tooth face than the yield limit under shear of material and improper lubrication method, which bring serious abrasion deformation of tooth face.
