Abstract
An accurate self-similar solution of the problem on hydrodynamic calculation of the thrust plain bearing that operates at viscoelastic lubricant under turbulent friction conditions has been found. Two fluid states are examined separately: 1) the lubricant is fed into the bearing under total relaxation of an elastic component of deformation, and 2) the lubricant should be under an unstressed state outside the bearing and subjected to sudden shear with a certain speed at the moment of its entering into the bearing. Analysis of the obtained analytical expressions for the bearing’s basic operating performances, including bearing capacity and friction force, makes it possible to design thrust plain bearings with turbulent viscoelastic lubricant, which operate with less power loss than similar bearings with laminar viscoelastic lubricant.
