Book Synopsis Predicted and Experimental Performance of Jet-Lubricated 120-Millimeter-Bore Ball Bearings Operating to 2. 5 Million Dn by : National Aeronautics and Space Administration (NASA)
Book excerpt: Bearing inner- and outer-race temperatures and friction power losses were calculated using two computer programs. The values obtained were compared with previously reported experimental data for 120 mm bore bearings which operated at thrust loads to 22 240 N (5000 lb), shaft speeds to 20 800 rpm, and with two lubricant flow rates. One program severely underestimated the power loss, while the other, called SHABERTH, provided a good prediction of both race temperatures and power losses. Coe, H. H. and Zaretsky, E. V.
