Design robustness and its effect on transmission error and other design parameters

摘要

Transmission errors, axial shuttling forces and friction result in bearing forces that serve as the major excitations of gear noise. This paper will use these factors as well as gear stresses and tribological factors to assist in obtaining optimal gear designs. The design basis comes from an actual application in which two different gear pairs were tested. One of the pairs was exceptionally noisy and the other exceptionally quiet, with the latter being insensitive to manufacturing variation.
