| Influence of Tooth Root Contour Deviations on the Tooth Bending Strength |
When testing gears with an unground tooth root area, form deviations from the heat treatment and manufacturing deviations from gear hobbing around the tooth root have a direct effect on the test results. These deviations lead to a change in the occurring tooth root stresses and influence the tooth bending strength (Refs. 8,11–16). In the following study, the influence of manufacturing-related geometry deviations around the tooth root on the tooth bending strength is investigated.
