Two-lobe journal bearings are applied in the responsible bearing systems of steam turbines, turbogenerators and compressors. As compare to the bearing with the cylindrical bush they have better stability in the range of higher rotational velocities and loads simultaneously assuring very good cooling conditions for the oil film. For the two-lobe journal bearing the oil film pressure, temperature and viscosity distributions have been obtained by iterative solution of the Reynolds’, energy and viscosity equations. An effect of supplied oil pressure on the maximum oil film temperature was investigated.
