Increasing demands on the performance of highly stressed gears result in the development of new materials. In order to account for these material improvements in future calculations of flank carrying capacities, the modelling concept is revised. This is done using a representative adaptation of the tooth flank carrying capacity and including the influence of the material properties and especially nonmetallic inclusions. The influence of inclusions is investigated focusing on failures due to flank breakage. With consideration of statistical methods, this data is transferred into an expanded model aimed at determining the failure probability. This model enables an estimation of the failure risk of a gear stage within the initial design phase.
