scope:

Explores a method to accurately predict gear root stress for parallel axis gears using a combination of three analysis techniques: boundary elements, elastic body contact analysis, and the moment-image method. The three techniques are combined to predict the stresses through the mesh cycle for both spur and helical gears. Predictions are compared with strain gage results and finite element modeling. Results present the prediction of load distribution factors as a function of misalignment, comparing with AGMA factors.
