Surface contact fatigue is the most common cause of gear failure. It results in damage to contacting surfaces which can significantly reduce the load-carrying capacity of components, and may ultimately lead to complete failure of a gear. Three types of contact fatigue damage are discussed, and a number of actual examples are presented to illustrate this failure mode in practice.
