Effect of Fillet Radius on Bending Stress in Helical Gear using FEA
Abstract: A well-optimized change in root fillet radius could greatly benefit helical gear operation by providing a smoother transmission with less impact and noise. The fillet area of the gear root is an area of extensive bending stress concentration. An increase in fillet radius for helical gears is considered to minimise the bending stress at the gear tooth's base. This paper develops appropriate models of various gear tooth profiles of the …
