Determination of the transition speed in journal bearings under consideration of bearing deformation

This paper discusses the further development of an analytical model to calculate the minimum film thickness and the transition speed in journal bearings with consideration of bearing deformations. The focus of the development was on generalising an existing model to include any relative eccentricities and width/diameter ratios. Furthermore, the influence of different bearing types and the layer structure of plain bearings on the deformation are taken into account. Using two white metal journal bearings as examples, the results of the new approach are discussed and compared with previous analytical models and full numerical calculations.
