Material optimization of spur gear tooth

Abstract

Gear is the most critical component widely used in the transmission of motion and power between shafts. During motion, the gears are loaded, which develops critical bending stress at the root of the gear and also at the point of contact. The loading point "Highest Point Single Tooth Contact" (HPSTC) is the most critical in any gear. The present research work involves a reduction in the weight of gear by optimizing material inside the tooth. This work involves removing material by making holes inside the tooth at different locations with different sizes. The FEM analysis leads to optimizing the material utilization and is carried out using ANSYS APDL tool. © 2020 Author(s).
