STRUCTURAL AND MODEL ANALYSIS OF A COMPOSITE MATERIAL DIFFERENTIAL GEARBOX ASSEMBLY

The main aim of the this project is to study the structural and dynamic behaviour of the gears in the differential gearbox assembly made up of the different composite material as compared to the conventional metallic materials as the Composite materials provide adequate strength with weight reduction and they have emerged as a better alternative for replacing metallic gears. The composites consider were the Aluminium Silicon carbide composite In this work an attempt has been made to replace the metallic gears of steel alloy with the composites For this purpose an parametric model of the differential gearbox was prepared according to the dimension calculated by the design equation on the creo 3. 0 cad software and Ansys 14.0 is used the analysis tool to detrmine the total deformation , von misses stress and the natural frequencies at various mode for the different materials relative to each other when the gears in the gearbox transmit power at dif ferent speeds i.e - 2400 rpm, 3000 rpm and 4000 rpm. The analysis results shows that the Composite gears offer improved properties over the conventional metallic gear and these can be used as better alternative for replacing metallic gears for the different ial gearbox apllication.
