| Abstract: | The three dimensional modeling for sector shaped tilting pad thrust bearings with polytetrafluoroethylene plastic pads and a numerical simulation with finite element method are presented. The thermoelastohydrodynamic methods for the babbit pad bearing could be used after some improvements. It is verified by the lubrication that, for the large and heavy duty bearing, the plastic pad bearing is a good solution. Predicted bearing operating characteristics show excellent agreement with field measurements. |
