A gearbox is a set of gears for transmitting power from one rotating shaft to another. They are used in awide range of industrial, power plant, automotive and home machinery application. A gear heads are available indifferent sizes, capacities and speed ratios. Mostly their main function is to convert the input provided by an electricmotor into an output of lower r.p.m and higher torque or high r.p.m and lower torque. This continuous transmission ofthe torque in gearbox increase the wear and temperature between to rubbing surface of gear teeth due to friction. Thegear oil which is use to reduce this friction loss have high viscosity. This viscosity of gear oil will increase power lossesof gear box. So this work is consent for find out power loss for same viscosity index gear oil. For finding this power lossin reduction helical gear box, three EP series gear lubricant oil (EP-90, EP-140 and EP-220) and one vegetable castoroil is considered for experimentation and the input power of gear box, output power of gear box, motor current andtemperature of gear oil is considered as response parameter. From this study, finally conclude that Power loss of Casteroil is less compared to other gear oil. The results of the experiments confirm with the existed CFD results.
