| dc.description.abstract | The main objective of this thesis is to analyze contact stress and estimate surface fatigue life in rolling-sliding contact of involute spur gear by finite element method (FEM). To do this three dimensional involute spur gear pair was developed in Solidworks 2012 Premium. This 3D model was imported to Ansysworkbench 14.5. FEM analysis was done after assigning displacement, load and support boundary conditions. The contact stress is analyzed and surface fatigue life is estimated. The results show that the contact stress in involute spur gear is agreeable with analytical contact stress by Hertz stress and the trend shows the error will decrease with higher load application. The contact stress also increases with higher friction in the area of contact .The surface fatigue life of involute spur gear was estimated using FEM and the result shows better surfaces which has less roughness result in high fatigue strength of the gear | en_US |
