In the post World War II era the major technology drivers for improving the life and reliability, and performance of rolling-element bearings and gears have been the jet engine and the helicopter. By the late 1950s most of the materials used for bearings and gears in the aerospace industry were introduced into use. By the early 1960s the life of most steels was increased over that experienced in the early 1940s primarily by the introduction of vacuum degassing and vacuum melting processes in the late 1950s. The development of elastohydrodynamic (EHD) theory showed that most rolling bearings and gears have a thin film separating the contacting bodies during motion that affect their lives. Computer programs modeling bearing and gear dynamics that incorporate probabilistic life prediction methods and EHD theory enable optimization of rotating machinery based on life and reliability. With improved manufacturing and processing, the potential improvement in bearing and gear life can be as much as 80 times that attainable in the early 1950s. The work presented summarizes the use of laboratory fatigue data for bearings and gears coupled with probabilistic life prediction and EHD theories to predict the life and reliability of a commercial turboprop gearbox and compares the resulting prediction to field data.
