The gear ratio assumed was 1.5 with a module of 10 and correction factor taken to be 0.5. In order to avoid undercutting and interference, addendum modification of the gear tooth is carried out in this paper, a standard and a profile corrected carried out spur gear pair is modeled. It can be clearly observed that 30.01 % of Equivalent stress, 10.21% of contact pressure is reduced& 12.51% of total mass is reduced when compared to baseline gear assembly with modified design.Ī gear is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part in order to transmit torque. By changing the current conventional design parameters we can achieve better performance of the gear under contact pressure as well as in equivalent stress while reducing the weight of the gear. Results are compared with Hertz contact stress. Analysis and Optimization of spur gear is done by using Finite Element tool. The purpose of this dissertation work is to identify the magnitude of the stresses for a Specified design and to optimize the weight of spur gear. As a result of that, gear tooth failures occur, so it is necessary to reduce it. Since the Spur gears are subjected to high loads in such machine tools, results in high contact stresses between mating gear tooth. Spur Gears are used in many machine tools to transmit the power like Lathe machines, Drilling Machines etc. The gears are the most common means to transmit the power.
