ISO 6336 Standard presents different methods to design cylindrical gears against bending fatigue.. The Standard allows the use of fatigue data obtained from plain and notched specimens to design gears, but it suggests a more experienced approach based on data obtained on reference gears. In this paper, the accuracy of the different methods was verified against test data. The estimation of material notch sensitivity was improved using experimental data obtained on specimens. After calibrating the notch sensitivity factors, the specimen-based methods proved to be as accurate as the method based on reference gears.

Abstract
ISO 6336 Standard presents different methods to design cylindrical gears against bending fatigue.. The Standard allows the use of fatigue data obtained from plain and notched specimens to design gears, but it suggests a more experienced approach based on data obtained on reference gears. In this paper, the accuracy of the different methods was verified against test data. The estimation of material notch sensitivity was improved using experimental data obtained on specimens. After calibrating the notch sensitivity factors, the specimen-based methods proved to be as accurate as the method based on reference gears.
