Abstract

This research developed a dynamic coupling-clearance model relating to gear train including gear backlash and sliding bearing radial clearance, and then built a dynamic model for the GTF star gear train covering dynamic couplingclearance. With this model, the effect of coupling-clearance on dynamics has been analyzed. The results show that: after introducing the coupling-clearance, the vibration response changes more complex, with a significant increase in vibration amplitude; as input velocity rises, the influence of coupling-clearance becomes more pronounced; however, as the input torque increases, the impact tends to decrease. In summary, the coupling-clearance significantly influences the operational characteristics of the gear train, notably in the context of high-speed gear trains.
