ABSTRACT:In Present work fabrication and mechanical study of LM6 Aluminum and Boron Carbide (𝐵4C) composites containing weight ratios of 5%, 10%, and 15% of Boron Carbide is done by Stir-Casting method. Mechanical tests such as tensile test, hardness test, and compression tests are conducted. Modelling and analysis tools like CATIAV5 and ANSYS 15.0 Work bench are used to model the spur gears and to perform finite element analysis. The project aims at the minimization of both contact stress as well as deformation using the composite materials. The results of the FEM analysis from ANSYS are presented. These stresses will be compared with the theoretical Hertz’s equation values. If both results agree well. This indicates that the FEM model is accurate. The contact stress and deformation of the gear teeth are the key parameters in designing the gear. When the working stress exceeds the maximum stress then the gears will be failed generally. The contact stress beyond the critical level causes pitting on the gear teeth. Gears undergo huge amount of compressive stresses in power transfer, so materials like LM6Al-𝐵4C composites are used as the compressive strength of this composite very higher than Aluminum and alloy steel. Finally the spur gears with different module and pressure angle are modelled in CATIAV5 and analyzed in ANSYS workbench 15.0, it was noticed that increase in module and pressure angle decreases the contact stress among the mating gears.
