Abstract: Gears are one among the most critical components in mechanical power transmission system. They have major applications in fields like automotives, industrial rotational machines, watches, lifting devices, etc. Gears are usually subjected to fluctuating loads while in action. Gear tooth mainly fails due to excessive bending stress and excessive contact stress. Thus it is very important to analyze the stresses induced in gear, while designing it for the safety operation. Weight reduction  of gear is also one of the most important design criteria as it has a great role in efficiency of the entire system. Engineering components made of composite materials and plastics find increasing applications nowadays. The components made from composite materials provide reasonable mechanical properties with minimum weight. In this paper, the spur gear and pinion assembly is modeled in “PTC Creo” and imported to “ANSYS Workbench 15.0” for static structural analysis. Analysis is done by considering different materials for gears like Structural Steel, Polycarbonate and AlSiC(20%).
