Abstract

Failure and pitting of teeth of gear affects transmission error. So, aim of this study was to define optimal tooth modifications introduced by performing static contact and deformation analysis, while trying to design spur gears to resist failure and pitting of the teeth. Behaviour of unusual contact between flywheel ring gear and starter motor pinion was analysed and optimized root fillet was introduced in spur gear. Starter pinion was analysed in ANSYS for deformation and maximum contact stress which causes pitting. Experimental Analysis was done using photo elastic method on photoelastic apparatus and compares the FEM result with experimental result. For this work parametric modeling was done using CATIA V5 and for analysis ANSYS workbench was used.
