Abstract : The prediction of five spur-gear efficiency calculation methods were compared with three sets of test data generated by different investigators using gear geometries. The prediction methods were those of Anderson and Loewenthal, Buckingham, Chiu, Merritt, and Shipley. The test data were those of Fletcher and Bamborough, Ohlendorf, and Yada. The data and the analysis methods were limited to jet lubricated, ground, spur gears. The data covered a range in pitch-line velocity of 1 to 20 m/sec(200 to 4000 ft/min) and K-load factor range of 17 to 1600.
