The fracture failure causes of a high-speed shaft in a hoisting gearbox were analyzed based on the optical microscope and scanning electron microscope analysis. The results show that the fracture failure cause of the high-speed shaft is fatigue. Surface defects, such as machining tool marks and folded cracks, are the source of fatigue fracture under stress.
