THERMAL ANALYSIS OF HIGH POWER REDUCTION GEARBOX

Abstract

This paper presents thermal analysis of high power reduction gearbox used for transferring power to surface mining conveyor belts. Gearbox is designed for continuous operation at high speeds, which results in generation of large amount of heat. Analysis is used to determine proper way of fan cooling which drains the entire amount of generated heat from casing. Thermal analysis of gearbox is performed for various convection coefficients out of which in this paper we presented two cases, one that satisfy and other that does not satisfy required conditions.
