An Analytical Method for the Determination of Temperature Distribution in Short Journal Bearing Oil Film

An Analytical Method for the Determination of Temperature Distribution in Short Journal Bearing Oil Film

The aim of this paper is to derive an equation for the temperature distribution in journal bearing oil film, in order to predict the thermal load of a bearing. This is very important for the prevention of critical regimes in a bearing operation. To achieve the goal, a partial differential equation o...
