The work deals with and solves the problem of the influence of installation of a damped roller bearing on the bearing surface area. The influence of the source of lubrication being fed in two different directions was considered. Also, anisotropy of permeability of porous layers for bearings with a single-layered and two-layer porous holder was considered. Cases of full and incomplete filling of bearing clearance by lubricant were considered separately. Results of numerical experiments are presented.
On the basis of full stationary Navier-Stokes and Darcy equations an asymptotic solution of the hydrodynamic calculation of the porous bearing of finite length is presented. On the basis of numerical analysis obtained in the analytical expression for the bearing capacity is established that when the permeability of the porous layer varies according to the same laws that form the lubricating film, the bearing in the bearing capacity possesses the dual action property. The effect of Reynolds number on the main bearing performance is assessed.
The Maxwell lubricant is widely used as a lubricant in bush bearings. Oscillatory features of the Maxwell viscoelastic layer are studied in the work. It is stated that oscillations have anharmonic character. The comparison of asymptotic solution with the exact one at large and small material viscosity.
