Gear s are one of the most critical components in mechanical power transmission systems. Today's competitive business in the global market has brought increasing awareness to optimize the gear design. The gears are generally used to transmit power or torque and the efficiency of transmission is very high when compared to other kind of transmissions. The helical gear offers high contact and more friction which avoids slippage when compared to spur gear. To estimate the bending stress, threedimensional solid models for different number of teeth are generated by CATIA that is powerful and modern modeling software and the numerical solution is done by ANSYS, which is a finite element analysis package. The analytical investigation is based on Lewis stress formula. The aim of the present study is to focus on reduction of weight and there byreducing the unbalance forces setup inthe system.
