This research paper explores the use of five different materials, including Gray Cast Iron (FG 350), Malleable Cast Iron (Whiteheart), Bronze (Sand Cast), Steel (30C8), and Cast Steel (Grade-1) Hardened & Tempered, for designing spur gears based on strength and wear criteria. The study varied the number of teeth from 17 to 25 and drew graphs for beam strength, wear strength, and total weight of the pair with the material as the legend. The results show that increasing the number of teeth improves strength irrespective of the material. Steel exhibits the highest beam strength, while Malleable Cast Iron (Whiteheart) has the lowest. Gray Cast Iron provides the maximum wear strength, while Bronze has the least wear strength. Furthermore, the overall weight of the pair is highest for Bronze and lowest for Gray Cast Iron. These findings can assist engineers in selecting appropriate materials for spur gear design, optimizing their performance and weight characteristics.
