Abstract

The lubrication is an essential element for the good working of the rolling. It has for objective to interpose a lubricant between the rolling bodies and the runway, in order to avoid the wear of the elements made of contact metal / metal between stationary and mobile parts that generate fast grippages of the surfaces in look whose repercussions are always catastrophic. The objective of this research is to put in evidence the optimal quantity of oil in a rolling and it impact on its life span. Tests of simulation are elaborated as well as the experiences on the rolling
