This research work describes the adiabatic model of a lateral slide bearing with a floating ring bearing. In order to support recommended assumptions for a designed model and for an evaluation accuracy of achieved results, the author developed a verification method which let comparing results received in a numerical way with that of the ones received in experimental tests. The evaluation criteria of a theoretical model were presented in regard to results from empirical studies. These criteria were divided into three groups. As the basic criteria, the author accepted the position of a bearing journal centre towards a fixed bearing bush, also for these positions pressure and temperature distributions in the outer oil film were chosen. In the conclusion, suggestions were made about the comparison of pressure and temperature distributions, frictional moments on a fixed bush surface, and angular velocities of a floating ring bearing towards a fixed bearing bush. The reasons of differences between measured and calculated values were also discussed.
Keywords: Floating ring bearing, bearing load, oil film, adiabatic model, eccentricity ratio.
