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 helical gear with the same loading conditions to obtain the results using structural analysis (ANSYS) and validate the results with standard theoretical stress. This study is an attempt to evaluate the impact of the root fillet radius on bending stress, strain, and total deformation.
Keywords: Helical gear, fillet radius, ANSYS, KISSsoft, AGMA stress.
