CFD Analysis Of Gear Oil For Oil Temperature In Helical Gearbox

Abstract

A gearbox is a set of gears for transmitting power from one rotating shaft to another. They are used in a
wide range of industrial, power plant, automotive and home machinery application. A gear heads are available in
different sizes, capacities and speed ratios. Mostly their main function is to convert the input provided by an electric
motor into an output of lower r.p.m and higher torque or high r.p.m and lower torque. This continuous transmission of
the torque in gearbox increase the wear and temperature between to rubbing surface of gear teeth due to friction. The
gear oil which is used to reduce this friction loss has high viscosity. This viscosity of gear oil will increase power losses
of gear box. So this work is consent for find out power loss for same viscosity index gear oil. Finally we conclude that
Power loss of Caster oil is less compared to other gear oil. The results of the experiments confirm that the CFD
represent a valid method to predict temperature of oil, CFD proves to be valid tool to investigate the parameters.
