Abstract
The main objective of this research work is to investigate the performance of automobile transmission gearbox under the influence of thermal properties variation of gearbox lubricant. An assumption has been made that the air-gear oil mist within transmission is under steady state condition, in isothermal equilibrium with the transmission gear oil bath of lubricant. The lubrication in multi speed transmission is subjected to thermo-elastohydrodynamic lubrication. The study here analyzed transmission in second gear pair. In full torque loading condition the high temperature generated due to meshing action of gears and frictional conditions between the transmission gear train changes the thermo-physical property of gear oil. The overall vehicle transmission gearbox performance is governed by the gear oil properties and it also effects the fuel consumption. This research study was performed at two higher different temperature range of gear oil.The analysis result shows that the gearbox oil thermal properties directly effect the performance and life span of automobile transmission gearbox.
