Finite Element Method Based on Involute Helical Gear Tooth Deflection of Contact Stress

Taking a pair of high-power planetary helical gear as an example,using Pro/E and ANSYS software,make finite element analysis to contact stress simulation of standard helical gear and deflecting helical gear.The results showed that,under same load,deflecting helical gear has a smaller contact stress,and contact stress has a more even distribution along tooth.So that deflecting gear has a better effect in improving contact stress between teeth.It also proved feasibility of finite element method in terms of gear contact analysis.
