PRESSURE AND CAPACITY FORCE IN JOURNAL LONGITUDINAL BEARING LUBRICATED WITH MICROPOLAR OIL

Journal Title: Tribologia - Year 2009, Vol 226, Issue 4

Abstract

This paper presents the results of the numerical solution for the Reynolds equation for laminar, steady oil flow in a slide plane bearing gap. Lubrication oil is fluid with micropolar structure. Materials engineering and tribology development helps to introduce oils with a compound structure (together with micropolar structure) as lubricating factors. Exploitation requirements incline designers to use special oil refining additives, to change viscosity properties. As experimental studies show, most of the refining lubricating fluids can be included as fluids of non-Newtonian properties with microstructure. In modelling properties and structures of micropolar liquid, one can introduce a dimensionless parameter within the terminal chance conversion of a micropolar liquid to a Newtonian liquid. The results are shown on diagrams of hydrodynamic pressure and capacity forces in dimensionless form in dependence on coupling number N2 and the characteristic dimensionless length of micropolar fluid Λ1. Presented calculations are limited to isothermal models of bearing with infinite breadth.<br/><br/>
