Analysis on the Influence for the Sectional Shape of Compound Pressure-Equalizing Groove to the Supporting and Bearing Characteristics of Precision Aerostatic Bearing

Abstract:

Static bearing capacity and static stiffness of pressure equalizing groove cross section with the same width and depth are researched in this paper, it can conclude that the trapezoidal section has the maximum static bearing capacity and static stiffness, while air consumption rate of unit load is the lowest. When compound structure annular hydrostatic thrust bearing has had the optimizing parameters, compared with the single structure one, the bearing capacity had a substantial increasing.
