Experimental and Numerical Study of Vibration Monitoring Applied on Gear Transmission Systems
Abstract
Predictive maintenance asks for efficient indicators and methods to detect incipient failures. Numerous studies have been made in this domain, but some difficulties stay to isolate the defected elements, to foresee through signal analysis, causes that produce faults, especially when different technological elements are involved simultaneously (gears, bearings, ...). In the first part of this paper, experimental study have been performed on gear faults: manufacturing faults (profile error, deviation, ...) and operating faults (wear, pitting,...) in order to establish a kind of data base for fault identification. Then, operating faults were examined and a procedure of identification of faults nature have been developed. Statistical treatment of both time and time- frequency (wavelet analysis) domains give arise to robust indicators. The second part deals with the definition of thresholds for machinery stops. Calculations of the dynamic behavior of the geared system show that how a gear fault modify the gear profile and the kinematic transmission error, while stiffness modification have almost no significant effect on the system response.
