Numerical and Theoretical Analysis of a Spur Gear Using Composite and Conventional Materials

A spur gear is one of the most common forms precision cylindrical gear. In industry, reducing weight gears while keeping their useful properties has become an even more pressing challenge. As a result, investigators have made many attempts to reduce gears. Despite these efforts, problem still requires research. This study presented gear's modeling and finite element analysis using different materials. three-dimensional was designed, modeled, simulated ANSYS software. Five materials, including two conventional materials (stainless steel copper alloy) three composite 50% carbon fibers reinforced in epoxy resin, 1.5% filler containing acetal, i.e., Graphene Reinforced Acetal, glass-filled polyamide. Composites were fabricated by varying graphene quantity Acetal nanocomposites. The stress calculated theoretically Hertzian equation, FEM analyzed 14.0 under limited loading conditions rotational speed. Although obtained results showed that both methods comparable, there significant difference between when resin matrix used, which 250.13 MPa. contrast, this result reduced up 152.13 MPa FEM. concluded among optimal material for fabrication due high strength low density. Hence, can be replaced matrix.
