Abstract:

An experimental study is reported of an externally pressurized, gas-lubricated, circular thrust bearing with central admission and operating in the inherent compensation mode. Gas supply pressures covered the range from 1.25 to 4.0 atmospheres, and three feed-hole radius to bearing radius ratios were investigated. The effect of recess depth was also examined. The film entrance pressure loss was investigated, and an empirical orifice discharge coefficient equation was used to predict load and flow curves for a bearing.
