Diagnostics of resource structural parameters of geared transmissions

Identification method for diagnostics of resource structural parameters of gearing of transmissions and reducers of agricultural machinery is suggested. The method is based on analysis of deformation of distribution density and correlation function of amplitudes of vibroacoustic impulses or impulses of shaft angular velocity on exceedance by mean value or by dispersion (following along with tooth changeover periods) of level corresponding to occurrence of defects and critical operating mode. Application of this method is investigated.
