Integral indicators as a diagnostic tool for multi-shaft drive gears

Abstract

The article presents the possibility of instrumental diagnostics of multi-shaft drives based on gears using integral indicators. They are formed on the basis of changes in informative frequency components (wave frequency fz, harmonics m? fz, multiples of them, and combined frequencies m? fz ± k? fo in the vicinity of the frequency of overstrain of the teeth).The use of integrated indicators reduces the amount of information analyzed and reduces the burden on the diagnostician.
