| Description | Journal: Journal of Physics: Conference Series This study developed a dynamic model of gear-pair system, involving nonlinear oil film force of hydrodynamic bearings and the gear mesh force with backlash. Based on this model, numerical simulations are made about instability led by the oil whirl in geared rotor journal bearing system. By comparing responses between single rotor journal bearing system and geared rotor system, evolution of oil whirl from individual rotor to adjacent geared rotors is examined. The results show that dynamic mesh force can transfer the excitations from the adjacent rotors, making different influences on the stability for individual rotors. The stabilities of the geared rotors are not independent with each other, but coupled by the mesh force. This coupling can be accompanied with tooth separation. |
