ABSTRACT:
The invention relates to a journal bearing for the shafts of high-speed rotors, and provides simple, and therefore low-cost, centering of squeeze film dampers for high-speed rotors, with improved long-term behavior, less installation space requirements and adequate concentricity accuracy. A centering element divides the annular gap into two partial annular gaps, with the bearing housing being configured in at least two parts and with a first bearing housing part bounding the first partial annular gap radially toward the outside and a second bearing housing part bounding the second partial annular gap radially toward the outside.
