A model of the signal of acoustic emission resulting from the normal wear of friction pairs is considered. Its mathematical description is obtained. Modelling of acoustic emission signals at varying strained/deformed state and rotation speed of initial friction pairs is done. The basic regularities of the transformation of acoustic emission form and those of its (emission) parameters of resulting signals are determined. Experimental research of acoustic emission signals is performed and proved to be good when compared to the results of theoretical research.
