Effect of Inertial Force on Thermal Elastohydrodynamic Lubrication of Oil Film Bearing in Rolling Mill Lubricated by the Oil-water Two-phase Flow

摘要

The oil film bearing in rolling mill as the research object in this paper is established oilwater two-phase flow of thermal elastohydrodynamic lubrication (EHL) model with the inertia force and thermal effect of the Reynolds equation. The oil film bearing in rolling mill in oil-water two-phase flow is analyzed the effect on the pyrolysis with considering inertia force, and the lubricant film pressure, film thickness with the changes in the relationship between water content, rolling force and spindle speed. The results showed that the lubricant film thickness is increased and carrying capacity is also increased with considering inertial force. With the increase of water content, lubricant film thickness is increased and the carrying capacity is decreased.
