Abstract：

The effect of transient on emulsion thermal elastohy drodynamic lubricated roll bearing was introduced. Thermal elastohydrodynamic lubrication film pressure and film thickness were compared in the thermal steady state and the thermal transient state. The mathematical model of thermal elastohy drodynamic elastohydrodynamic lubrication of roll bearing was established considering the transient effect. The distributions of lubricating film pressure and film thickness were obtained by numerical simulation using the multi-grid method for pressure, the multi-integration method for deformation and the column scanning method for temperature rise. The calculation results show that the influence of the transient effect on thermal elastohydrodynamic emulsion film pressure is very small. But it is serious for the influence of film thickness. The film thickness of transient effect is far less than the steady film thickness.
