There are many factors that affect the damage of the gear, such as material selection, processing technology, and so on. In the work of the gear in the basic form of damage is divided into five categories: wear, tooth surface fatigue, glue, plastic deformation and gear broken, etc..

Gear abrasion refers to the process of continuous friction and consumption of the gear in the gear box. According to the damage mechanism of wear can be divided into adhesive wear, abrasive wear, surface fatigue wear, corrosion wear etc.. According to the depth of the gear wear can be divided into minor wear, moderate wear, over three kinds of wear. Gear two meshing tooth surfaces of metal, adhesion wear is direct contact under a certain pressure, welding and relative motion, metal from the tooth surface tear down, or from a tooth oriented another tooth surface transfer caused by damage phenomenon. The engagement of the gears is actually a process of relative motion and relative sliding. The action of these two forces causes the shear stress of the surface layer of the gear to produce a pulsating cyclic variation. Under the action of the shear stress, the tooth surface can cause damage to the local metal. The damage forms and pitting fatigue spalling, shallow fatigue spalling and fatigue spalling of hardened layer three.
