Inverse evaluation of equivalent misalignment under real operating mode and redesign of aviation spiral bevel gears

A new inverse evaluation of equivalent misalignments was approached by using the numerical characteristics extracted from the actual loaded contact patterns. The approximation linear relationship between loads and deflections was applied to determine the unique solution of equivalent misalignment from multi-solution. By detecting the numerical characteristics of two sets of loaded contact pattern, the inverse evaluation of equivalent misalignment was validated to be accurate. The redesign was accomplished by consideration of the equivalent misalignments. The redesign can simulate the real operating mode and get better operating performance of spiral bevel gears.
