Abstract

A mathematical model for multilobe journal bearing with axial lubrication is discussed. An approach is offered to consider complex configuration of the bearing radial clearance by differential equations solving. The proposed model takes into account impact of lubrication boiling, film turbulence, compressibility upon pressure field formation. Computation of the pressure field in lubrication layer as well as computation of carrying capacity and power losses caused by friction is presented.
