Stratified flow of three-layer lubricants in the gap of the elastically deformed radial bearing with increased load bearing capacity and damping characteristics
On the basis of the Navier - Stokes equations, the continuity equation, Darcy equation and Lame equation for the case of a «thin layer», the problem for stratified flow of three-layer lubricants in the gap of elastically deformed bearing with adapted profile supporting the surface in the presence of a porous layer on the surface of shaft is solved. As a result, the field of velocities and pressures and analytical expressions for the components of the lifting force were found. By using the numerical analysis of the obtained expressions, the influence on the bearing capacity of parameters characterizing: the adapted profile of supporting surface, ratio of layers viscosity, deformation of the bearing surface and damping characteristics of the bearing. The results obtained are the prerequisite for the development of a resiliently deformable bearing running on a three-layer lubricant with increased load bearing capacity and damping characteristics.
