... of surface asperities. Fretting commonly occurs in joints that are bolted, keyed, and press-fitted, and in splines and couplings. It could occur on gear teeth and bearing raceways and rollers under specific conditions where the gears and bearings are not rotating and subjected to structure-borne vibrations...

... lubricants. Gear-Tooth Contact The way in which tooth surfaces of properly aligned gears make contact with each other is responsible for the heavy loads that gears are able to carry. In theory, gear teeth make contact along lines or at points; in service, however, because of elastic deformation...
