Abstract:A nonlinear dynamic model of planetary gear train coupleing with sliding bearing is established by taking nonlinear oil film force of the bearing and backlash of the syetem into account. Some coupling nonlinear dynamic characteristics of the system are studied by using numerical simulation method. The study results reveal that slide bearing nonlinear oil film force can calm the meshing frequency vibration of the moving parts of the planetary gear train, but it also can make the oscillation rule of the dynamic meshing loads of the gear pairs get in chaos; The change of the input shaft speed can lead to the vibration of the bearing force bifurcate between the periodic motion and chaos; the influence law of the bearing clearance on the gear pair meshing state of the system is a very complicated nonlinear relationship, and an improper bearing clearance value may lead to unilateral impact phenomenon. © 2018, Editorial Board of Journal of Ship Mechanics.
