Contact Stress Analysis Of Helical Gear System
Subject area: Science,Engineering and Technology · Area of research: Mechanical Engineering
Abstract
This research investigates the characteristics of an involute helical gear system mainly focused on contact stresses induced between two gears using analytical and finite element analysis. To estimate the contact stress, three-dimensional solid models for different helix angles (20,23˚,26˚,29˚,32˚ and 35˚) are generated by SolidWorks software 16.0 that is a powerful and modern solid modelling software and the numerical solution is done by ANSYS. The results obtained from ANSYS are presented and compared with theoretical values. The analytical investigation is based on AGMA stress formula. The main objective of this research has to analyse the stresses induced between two gears by changing six different helix angles (20˚, 23˚, 26˚, 29˚ 32˚ and 35˚). Contact stresses analysis is also carried out for three different materials (AISI 5160 OQT 400, Stainless and Structural Steel) and the results are compared.
