Gears are the very useful components in mechanical power transmission system and industrial rotating machinery. A spur gear generally subjected to two types of stresses like bending stresses and contact stresses which are causes teeth failure during meshing with another tooth. Gears are generally made from metallic materials but recently advanced polymers were developed which have sufficient strength and properties similar to the metallic materials so they can easily replace the metallic gears

Nylon, polycarbonate, acetlas and delrin are the structure polymer materials used in printing and robotics mechanism with good functionality but polymers gears are not used in heavy loading type application. Especially polymer gear gives extra benefits compared to metallic gears like less noise-vibration, low requirement of maintenance-lubrication, low cost and easy manufacturing. This paper presents the design optimization methodology step by step using a static finite element method. Keywords: Metallic and non metallic material, bending stress, static finite element analysis, facewidth, module, composite material.
