Analysis of Maximum Stress due to Bending in Helical Gears: Comparison Between the Agma Method and Finite Element Analysis

Resumo

This study presents a methodology for designing helical gears based on Shigley's calculation approach and AGMA standards, including the calculation of maximum bending stresses and the application of safety factors. The analytical results were compared with numerical results obtained from a structural analysis using the Finite Element Method (FEM), applying the von Mises yield initiation failure criterion. The methodology involved defining geometric and operational parameters, calculating the tangential load, and considering overload factors to achieve more realistic simulations. The maximum stress obtained from the finite element analysis showed a 3.85% difference relative to the analytical calculation from the AGMA standard, demonstrating good agreement between the methodologies.
