Abstract
The bearing characteristics, such as bearing stiffness and damping coefficient, of an externally pressurized gas-lubricated thrust collar bearing with multiple supply holes are analyzed theoretically. A point-source solution is applied to strictly evaluate the bearing characteristics. The dispersion effects due to the discrete location of the supply holes are discussed by comparing the point-source solutions with the solutions obtained under the line-source assumption. The effects of the deviation of bearing forms, such as the perpendicularity of the rotor end surface, size deviation of the supply holes and flatness of the bearing plate, on the bearing characteristics are also discussed.
