Description
Summary:Gears are one of the oldest and most significant innovations of humankind and these are used in many fields such as power transmission and so on. Usually, gear is utilized for power transmission in the form of motion. When it comes to parallel axes transmission involute spur gear is more frequently used due to its simpler designing structure and manufacturing. However, structural failure occurs at the root part as a consequence of high bending stress. In this paper, it portraits a detailed analysis of bending stress and deformation at different root radius of the gear using two FGM material AISI4140 alloy and Ti6242S alloy. Through this context, it was found that for AISI4140 alloy with root radii 1.2 mm undergoes less deformation compared to Ti6242S alloy with 1.2 mm root radii.
