CALCULATED MODEL OF HEAVY DUTY RADIAL BEARING WITH THREE-LAYER GREASING SUBJECT TO THE DEPENDENCE OF VISCOSITY ON PRESSURE
The method of formation of the exact automodel solution of the problem of hydrodynamic calculation of a radial bearing with adapted profile working on three-layer lubricant on the basis of Navier -Stokes's equations, and the continuity equation taking into account the dependence of viscosity on pressure is given in the work. As a result the field of speeds and pressures in lubricant layers is found, and analytical expressions for components of the supporting force vector and the friction force are obtained. Rational values of parameters of bearing capacity that characterize the various aspects of functioning of the considered unit of friction are found. They are: the profile of the basic surface; special interactions of lubricant liquid with surfaces in the friction unit (formation of intermediate layers of greasing with different viscosities); dependences of viscosity on pressure.
