Abstract
To decrease the wear between the journal 6, and the hydrostatic bearing 1, especially during start up and shut down of the turbomachine, a rub ring 5, is employed intermediate the journal and bearing. The rub ring will come into contact with the journal before the bearing and prevent contact with the bearing bore. The rub ring also serves to block the leakage of the fluid from the bearing. This interrupted flow causes an increase in the stiffness and damping coefficients of the hydrostatic bearing. The use of the rub ring increases the life of the bearing, improves the rotordynamic performance, reduces the leakage flow and improves the hydrodynamic performance of the hydrostatic bearing.
