Gear tooth breakage due to bending fatigue is one of the most dangerous failure modes of gears. Therefore, the precise definition of tooth bending strength is of utmost importance in gear design. Single tooth bending fatigue (STBF) tests are usually used to study this failure mode since they allow to test gears, realized and … WebThe gear flanks are inspected after each load stage for scuffing marks by visual inspection. Failure is considered if the faces of all the pinion teeth show a summed total damage width, which is equal to or exceeds one tooth width. In the gravimetric test the gears are dismounted and weighed to determine their weight loss. havilah seguros
