Objective of this work is to punctually characterize the strain fields in standard and thin-rim spur gears during bending static conditions to complete and deepen a research already carried on by the authors in previous papers about the influence of gears geometry on bending crack failure. Strain profiles of two gears, standard and thin-rim respectively, were acquired and processed, so the corresponding local strain distribution was obtained. Numerical Finite Element Method simulations were run to compare and verify the corresponding experimental data. Basing on experimental and numerical obtained results, the phenomenon of the different crack propagation modes, leading to fail safe or catastrophic failure, was thoroughly analysed and interpreted.

Abstract
Objective of this work is to punctually characterize the strain fields in standard and thin-rim spur gears during bending static conditions to complete and deepen a research already carried on by the authors in previous papers about the influence of gears geometry on bending crack failure. Strain profiles of two gears, standard and thin-rim respectively, were acquired and processed, so the corresponding local strain distribution was obtained. Numerical Finite Element Method simulations were run to compare and verify the corresponding experimental data. Basing on experimental and numerical obtained results, the phenomenon of the different crack propagation modes, leading to fail safe or catastrophic failure, was thoroughly analysed and interpreted.File | Dimensione | Formato | |
