Abstract	This research paper discusses a novel method to prevent the tooth failure in the spur gear by introducing circular root filet instead of standard trochoidal root filet in the gear. In general, gears with less than 17 teeth had the problem of undercutting during gear manufacturing process depending on the tip radius of the hob (cutter) which minimizes the strength of the gear at the root. Analysis is carried out using ANSYS software version 11.0 for the existing standard design gear teeth as well as the proposed design gear teeth to evaluate the performance. In order to facilitate the analysis, the gear tooth was considered as a cantilever beam and the tooth force was applied normal to the profile at the highest point of single tooth contact. The study reveals that the proposed design (circular root filet) exhibits higher bending strength rather than the standard trochoidal root filet design.
