dc.description.abstractIn order to elevate the helical gears’ performance, durability, and reduce teeth regarding failures, this study measures the parameters from the non-functional fractured helical gear model and modifies them in order to construct a highly efficient helical gear. The model of an optimized helical gear is designed with the use of the SolidWorks software along with a complementary opposite hand pinion the parameters of which have been carefully calculated to ensure an ideal mesh between the gear pairs. In addition, surface roughness measurement has been implemented on the non-functional helical gear model in order to evaluate the texture of the provided model’s helical teeth. As a result, it has been identified that the surface quality of the helical gear teeth was completely deviating from the standard and several methods in regards with the maintenance and manufacturing process have been discussed in order to eliminate the unpleasant surface roughness results and improve the overall efficiency and durability of the helical gear. Lastly, a static structural analysis on mated helical gear pair with a denser mesh around the teeth has been carried out with the use of the ANSYS software to analyse the structural behaviour, deformations, and stress distributions. With the application of three different loads, it has been observed that the greatest stress and deformation were present at the rim of the helical gears instead of the teeth. This shows that the optimized geometric design of a gear and a pinion that included a creation of an appropriate involute teeth profile with an increased helix angle, tooth thickness, addendum, and number of teeth can withstand these operating loads to some extent, which implies that the current research has significantly improved the overall efficiency of a nonfunctional helical gear.
