Abstract

The characteristics of the non-stationarity of vibration signals of a radial rolling bearing with a deviation in the installation of the outer ring of the bearing have been investigated. The high sensitivity of the degree of non-stationarity of the vibration signal to the error in the installation of the bearing has been shown.
