Оценка вибросостояния дифференциальных редукторов турбовинтовых двигателей перед их ремонтом

Abstract

On the ground of statistical analysis of reducers vibration, came in for repair, it was made an attempt to obtain the connection between maximum value of gear teeth wear and an intensity corresponding to the previously proposed diagnostic features. Substantial variation data was determined and the availability of engines teeth reduction gear wears higher than normal, but below the level of diagnostic signs preliminary baseline. Based on the work of one of the engines, we evaluated the impact of his achievements on the change in the intensity of these symptoms, the overall level of vibration and the n-dimensional vector of a number of multiple harmonics, including claw Vibrodiagnostic composes and signs.
