Abstract
Presently, robots have widespread application in mechanical processes, automation, healthcare, food processing, etc., where the motion of robots majorly depends on the precise gear transmission and type of gear to be used. The primary aspect considerated in redesigning of the sun and planet gear mechanism are the pressure angle and face width of the gears. Static and dynamic analyses of the redesigned planetary gear are performed using ANSYS 2021 R1. To ensure accuracy of the analysis, a mesh-independent study was carried out to obtain an optimal element size. The static analysis results reveal the total deformation and Von-Mises stress occurring in the planet gear due to the rotation of the sun gear. The secondary objective of this study is to compare the natural frequencies obtained from the numerical modal analysis for two different types of material: 20CrNi2Mo alloy steel and titanium alloy. In a nut shell, the findings of this research provide a foundation for understanding the sun and planetary gear system's static and modal responses for its improved efficiency.
