The paper describes features of new construction pad-type (segmental) hydrodynamic bearing with mobile ring and results of investigations of this bearing. The researchers obtained complex method of interaction between the mobile ring and pads. Except the diagram of distribution of lubricant pressure on the surface of pad there are presented photos of the flowing lubricant in the bearing and graphs of trajectories of the rotor journal’s axis for various number of revolutions of the rotor. Presented results of investigations show high stability of new construction hydrodynamic bearings in case of big number of revolutions of the rotor. Researchers hope that new construction bearings can be successfully used in tribological systems at the mentioned condition.
