Static and Dynamic Analysis of Selective Leverage System Gear Train

Abstract

Nowadays, the mechanical advantage is strongly emphasized in a mechanical system. Therefore, the most modern gearboxes are used to increase the torque without also increasing their output speed while reducing it. In this study, Selective Leverage System (SLS) gear train is generated in Solidworks 2016 and together with dynamic motion study and static simulation analysis. Dynamic motion analysis is performed to provide output speed of SLS gear train. It can be concluded that the gear system runs with unchanged speed (RPM) for input and output which is approximately the same with theoretical value in Selective Leverage System patent. The maximum output torque is evaluated by using theoretical calculation. At every 90° rotation, maximum value of output torque is produced. The results are validated and compared to the analytical value of patent. For static simulation analysis, the stress distribution of T-shaped lever of Selective Leverage System gear train is identified by using composite material compared to the existing gear materials. The static simulation analysis between Aluminium Alloy, S45C Steel, Malleable Cast Iron and Glass Filled Polyamide are compared and composite materials are capable to be used as a material of gear train components instead of current material, S45C Steel for better result.
