Early Failure Study of Gearbox Input Shaft Bearing on Damage Rate
(0) In the non-road vehicle transm ission systems,it always has early dam age in the input shaft bearing.Gearbox simulation model is established by Rom ax software.Based on the different load spectrum of all shaft bearings and Adjusted bearing damage rate prediction method (instead of ISO 281),rolling bearings are simulated and compared with the actual useful state of those bearings,the results shows that early fretting wear and failure appear on the inner raceway of both input shaft bearings that are connected to engine flywheel due to the vibration of flywheel,input shaft bend,etc.After further study on this failu re,the fretting wear mechanism model of input sh aft bearing is proposed so that it provides a theoretical reference for the assessment and design of bearings on damage rate of Adjusted method.
