BEARING ASSEMBLY WITH AN OIL DAMPER

摘要

A high speed generator with a hydraulic rotor mounting system (300) that dampens rotor vibrations at the rotor S critical speeds. Oil is supplied to a gap (370) formed between the outer race (3, 4) of the rotor bearing assembly (3, 0) and the bearing liner (320). The oil provides soft bearing support for, and viscous damping of, the rotor (132) by squeeze film damping.
