FIELD: physics.
SUBSTANCE: acoustic emission signals are measured on the housing of the diagnosed reducing gear at an informative point away from bearing assemblies. The value of overshoot of the maximum amplitude of acoustic emission signals is evaluated in the given frequency band from 30 kHz to 300 kHz at equal successive time intervals with sampling frequency from 50 microseconds to 0.1 microseconds. The deviation of the state of the diagnosed transmission from the standard is determined based on the established level and duration of maximum time-continuous acoustic emission signals. The standard is a single-type mechanical transmission in which there are no mounting defects, mechanical wear and oil deficiency in gears and bearing assemblies.
EFFECT: shorter time for determining the technical state of transmission elements of mining and production machines.
