| Summary: | Taking the hydrostatic thrust bearing having double rectangular cavity multi-oil pad as the research
object，the influence of the eccentric load distance on the bearing lubrication performance under high speed and
heavy load conditions is discussed and compared with the lubrication performance at the center loading. The flow
rate equation，temperature rise equation and oil cavity pressure are deduced and calculated by lubrication theory
and tribology principle，and the simulation analysis is carried out. Ｒesearch result shows that the load is constant，
as the offset distance increases，the thickness of the oil film on the downside of the table gradually decreases，and
the temperature rising and maximum pressure of the oil film gradually increase; the thickness of the oil film on the
upside of the table gradually increases，and the temperature rising and maximum pressure of the oil film gradually
decrease. The eccentric load distance is further increased，and the hydrostatic bearing will have a loss of pressure
and tribological failure. |
