The problem of establishing of the thermal gradient inside the film lubricant was widely taken into account during the last ten years and that for the obtaining more information about the lubricant conditions. The energy equation gives the instantaneous temperature in film lubricant and it is solved together with the viscosity and density equations. There is, finally, a highly nonlinear system of equations which can be solved by various mathematical methods. This paper presents a mathematical model for solving the energy equation by the aid of a program made in MathConnex2000.
