AB  - Presented work combines the knowledge presented in literature and own experimental works concerning characteristics of fatigue damage of cog-wheels. Material damage of the cog-wheel tooth sides at their relative movement is demonstrated in terms of microstructure. Development of damage is described with respect to presence of micro-cracks, their connection to another type of structural discontinuities and lubricant influence. The location of pitting damage is exactly determined on the base of experimental results. The conclusion of the work clearly determines the nature of pitting damage of cog-wheels evoked by fatigue loading, presence of under-surface inclusions and effect of lubricant pressure.
