Measurement and Analysis of Torsional Vibration Signals for Diagnosing Planetary Gearbox Faults
摘要
Abstract
Planetary gearbox health is of great importance for the flight safety of the helicopters.They were usually operating in harsh conditions,so the faults occured easily,such as petting and fatigue cracks.The incremental encoder was presented to measure torsional vibration signals from planetary gearboxes.The torsional vibration signals of the input shaft and the output shaft were measured respectively,and made some contrastive analysis to the signals sensitive for planet gear faults,the re sults show that the input shaft is more precise than output shaft for diagnosing faults.Via comparing the effects over heavy loads,the torsional vibration signals of the output shaft are more sensitive to the fault features.关键词
