Description
Summary:The asymptotic solution to the problem on the hydrodynamic calculation of the porous double - layer r a dial finite length bearing is provided on the eccentricity ratio levels. The solution is based on full nonlinear Navier — Stokes equations, and on Darcy’s equation. The distinction of the suggested design model is that it allows for the perme ability anisotropy of the porous layers, and availability of a greasing source. A case when greasing forcibly gets thro ugh pores of an external porous layer is considered. A velocity and pressure field in the lubricant and porous layers is found. As a result, analytical expressions for the main performance data of the bearing ar e obtained. The effect of the permeability an isotropy of porous layers, nonlinear factors, as well as the influence of a greasing source on the basic performance chara c teristics of the bearing are evaluated.
