Gears are used for speed and torque variation. since gears are rotating parts gear teeth tends to wear and thus crack occurs, to overcome this crack and to obtain higher efficiency gearbox can be analyzed before production. Spur gears and the shafts are designed using SOLIDWORKS and then it is subjected to stress analysis in ANSYS. Stress concentration factor is compared under varied loads. The main objective for carrying out this analysis is to improve the life of the gear. After the analysis of gears from existing gearbox the reason for failure was found. The reason for failure of the gear was due to wear of gear teeth edges. This is caused due to high stress concentration along the gear teeth edges. To relieve these stress concentration gear material can be changed so that the resulting stress can be reduced according to the properties of the materials used. The resulting stress of all the materials are compared and the best material is chosen.
