Contact stress analysis of xylon coated spur gear using ANSYS workbench

One of the most crucial mechanical components of a mechanical power transmission system is the gear. To transfer torque, a spinning machine component with cut teeth meshes with another tooth component. Due to their great degree of versatility, gears are used in a broad variety of applications, from small wristwatches to massive heavy equipment like those used in the automotive and aerospace industries and marine engines. Contact stress and bending stress are therefore the two key factors that affect gear failures. In the current study, a static stress analysis is carriedout on the spur gear part to figure out the equivalent stress, total deformation, and stress intensity. Additionally, the component's possible fracture point is also located. Many materials, such as xylon, PTEF (polytetrafluoroethylene), and boron carbide, are used to increase the gear lifespan with the intention of reducing contact stress. Coated materials in gears are chosen because they are readily available and low-friction, and they are compared to conventional gear.
