This year, the AGMA's Fall Technical Meeting will be held in Chicago on November 2-3, 2021. Although some presentations will be pre-recorded because of continued Covid travel restrictions, most presentations will be in-person. The AGMA's Fall Technical Meeting brings together top researchers from across the globe who will provide the latest information on their peer-reviewed gear industry research.
Dr. Fuentes will be attending the 2021 AGMA's Fall Technical Meeting and presenting the paper entitled "Investigation of the Effect of Application of Non-Conventional Root Profiles for Reduction of Bending Stresses in Helical Gear Drives" in Session 1 on Tuesday, November 2, 2021.
Abstract:
Studies of non-conventional root profiles have mainly used finite element models in which the load is applied at the highest point of single tooth contact. The adjacent pair of teeth, when they carry part of the load, cause compressive stresses on the root area. This study will provide the variation of the alternate and mean range normal stresses on the root surface in the longitudinal direction of the gear teeth for tooth root profiles based on Hermite, elliptical, and Bézier curves and their comparison in terms of the mentioned stresses with those obtained for conventional root profiles. Such variation will be obtained for two cycles of meshing by considering finite element models with five pairs of teeth so that the effect of load sharing between adjacent pairs of teeth is considered.
