Analytical Description of Mass Transfer of the Lubricating Material Near The Surface of the Porous Component of the Tribocouple

摘要

The process is discussed how the lubricating layer is replenished from the body of a porous oil-filled slider bearing. It is shown that the ideas of capillary flow in such systems only by the effect of the Laplace force fail to describe the process satisfactorily. A kinematic mathematical model is advanced describing the flow with the Bernoulli and Navier-Stokes equations. The model enables to take into account the characteristics of the porous system of the bearing and predict its service life in the self-lubrication mode.
