• A failure mode called 'flank breakage' is increasingly observed in different applications of cylindrical and bevel gears. These breakages typically start from the active flank at mid tooth height and propagate to the tooth root of the unloaded flank side. Crack initiation can be localized below the surface in the region between case and core of surface hardened gears. Mostly several parallel cracks can be recognized with one main fragment and several smaller pieces breaking out of the flank. This failure cannot be explained by the known mechanism of tooth root breakage. Therefore the German Forschungsvereinigung Antriebstechnik e.V. (FVA) initiated the research project No. 240/II to investigate the described failure mode in bevel gears and to develop a calculation method to predict the risk of flank breakage of such gears. The project was carried out at FZG (Gear Research Centre) at the Technical University of Munich (TUM), Germany. In the following the fundamental results of this research work are presented.
