A well known empirical relation for abrasive wear as functions of sliding velocity, contact pressure and sliding distance is applied to silulate the tooth flank wear of hypoid gears. The simulation for stress state of hypoid gears has incorporated to obtain the state of tooth flank wear, and using this state of worn tooth flank form, the change of gear performance with progress of tooth flank wear was investigated. The simulated results for the deterioration of tooth contact pattern correspond well to the observed state of tooth flank contact pattern of actual automotive hypoid gears. This simulation also reveals some characteristics of the tooth flank wear of hypoid gears, for instance, the root of pinion tooth flank is prone to severe wear. The characterisitcs of gear performance change due to tooth flank wear is also shown, and it is clarified that the no-load contact pattern of worn hypoid gears tend to be line like at root of wheel tooth.
