Powder Lubricated Bearing Operation to PV of Half a Million
Heshmat, H. and Kaur, R.G. “Powder Lubricated Bearing Operation to PV of Half a Million,” 2nd World Tribology Congress, Vienna, Sept. 3 – 7, 2001, (2002) Tribology Series, Volume 40, pp. 477-480.
Based on the quasi-hydrodynamic analytical developments and some preliminary experimental work, a large size self-contained powder lubricated journal bearing was designed and developed to operate at high record breaking PV values (PV=532,000 psi.ft/sec). Self contained backup bearings are essential and required for magnetic bearing supported rotors in flywheel energy storage systems, auxiliary power units/integrated power units, and gas turbine engines.
