| Abstract: | Major heat sources which have effects on thermal behavior of bearing oil are analyzed. The models for calculating bearing heat generation, graphite seal heat generation, heat input leaking from the graphite seal, convection coefficients and temperature fields of the bearing oil cavity are established, which lays the foundation for the calculation of both temperature fields of the bearing oil cavity and optimal oil supply of engines. |
