WebThe fatigue analysis revels that the drive shaft fails in the region of high stress concentration as expected. The fatigue life of the component is found to be infinite for design pay load. The life of the drive shaft for 40% and … There are only four basic failure mechanisms: corrosion, wear, overload and fatigue. The first two— corrosion and wear —almost never cause machine-shaft failures and, on the rare occasions they do, leave clear evidence. Of the other two mechanisms, fatigue is more common than overload failure. See more Fig. 1 The appearance of an overload failure depends on whether the shaft material is brittle or ductile. Whether related to motors, … See more No shaft materials are absolutely brittle or absolutely ductile. The shafts used on almost all motors, reducers and fans are low- or medium-carbon steels and relatively ductile. As a result, when an extreme overload is … See more Fatigue failuresFatigue is caused by cyclical stresses, and the forces that cause fatigue failures are substantially less than those that would cause plastic deformation. Confusing the situation even further is the fact that … See more In diagnosing which mechanism caused the failure, a critical point to remember is that overload failures are generally caused by a single load application, while fatigue failures are always … See more
