CONTACT STRESS ANALYSIS & OPTIMIZATION OF SPUR GEAR BY FINITE ELEMENT ANALYSIS
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 4
Abstract
The gears are the most common means to transmit the power. Spur Gears are used in many machine tools to transmit the power like Lathe machines, Drilling Machines etc. Since the Spur gears are subjected to high loads in such machine tools, results in high contact stresses between mating gear tooth. As a result of that, gear tooth failures occur, so it is necessary to reduce it. 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. Analysis and Optimization of spur gear is done by using Finite Element tool. Results are compared with Hertz contact stress. 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. 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.
