Experimental Study of Sideband Harmonics in Vibration Spectrum of Two-Stage Planetary Gear Box for Condition Monitoring

Abstract

The fault diagnosis via condition monitoring of a two-stage planetary gearbox using the vibration signal processing techniques is the aim of the present work. The online vibration data were recorded for a set of normal gear and gear with fault, at a particular speed and various loading condition using Drivetrain dynamics simulator setup. A spectral analysis is carried out in order to demonstrate and examine the presence of sidebands activity around the gearmesh frequency resulting from the localized tooth fault, viz, broken tooth. The chapter is to investigate and develop an understanding of the sideband activities around gearmesh frequencies of a double-stage planetary gearbox. © Springer Nature Singapore Pte Ltd 2020.
