Abstract: Finite element analysis of a straight bevel gear tooth was carried out to evaluate the bending stresses. The stresses obtained by theoretical calculations at the root of the tooth are compared with the analytical results obtained using ANSYS software. Modeling was done by using Solid Works software. Bending stresses induced in bevel gears were determined by taking specifications of an automobile differential. A software program was developed using PHP web programming language to calculate the bending stresses for three different materials and five pitch angles. Numbers of iterations are carried out using the software to obtain the desired factor of safety. The analysis results obtained in ANSYS and theoretical results are good in agreement.
