Abstract:

The objective of this program was to develop analytical methods for the selection of dry lubricated helicopter control bearings for specific conditions of use. The conditions of use include static radial pressure, cyclic radial pressure, speed of ball oscillation, angle of ball oscillation, static axial load, contamination, and combinations of these variables. Performance was measured by radial clearance which was directly related to wear. Sixty-one bearings were tested in three wear test rigs. The wear test results were used to develop wear life equations. Three approaches to equation development were utilized in this report empirical, deterministic, and theoretical. Author
