THE EFFECT OF THE CONCENTRATION OF MAGNETIC PARTICLES ON THE OPERATING PARAMETERS OF A SLIDE JOURNAL BEARING LUBRICATED WITH FERRO-OIL
Journal Title: Tribologia - Year 2019, Vol 284, Issue 2
Abstract
This paper presents an analysis of changes in basic operational parameters of a slide journal bearing in an aspect of a concentration of magnetic particles in ferro-oil as a lubricant. The first part of the article presents an analytical-numerical calculation model. This model is based on experimentally determined physical parameters describing the dependence of ferro-oil viscosity on changes at basic operating parameters. Moreover, dimensionless load carrying capacity, dimensionless friction force and dimensionless coefficient of friction numerical calculations have been obtained by solving the Reynolds type equations using the finite difference method in Mathcad 15 program and the author’s own calculation procedures. The obtained results have been presented in the form of graphs taking into account the influence of the following factors: external magnetic field, corrections related to the influence of pressure changes, corrections related to the influence of temperature changes and corrections related to non-Newtonian properties of the ferro-oil. The analysis of the obtained characteristics in the paper has been carried out, observations have been made as well as conclusions have been drawn regarding the optimal concentration of magnetic particles in the ferro-oil lubricating the slide journal bearing.<br/><br/>
