Design and thermal characteristic analysis of gearbox system based on finite element analysis (FEA)

Abstract

The chief aim of this study is to analyze the thermal performance of transmission gearbox using varying parameters such as load, rotational speed and types of gear oil. SAE 80W-90 was selected as gearbox gear oil. An assumption of under steady state condition and isothermal equilibrium was made. By varying the loading conditions, the thermal performance of gearbox system has been evaluated. FEA based steady state thermal analysis was performed. The analysis demonstrates that the oil thermal characteristics directly affect the performance of the gearbox.
