| Abstract: | This paper presents a method for calculating heat conduction and thermo-elastic deformation of double-disk supported thrust bearing by means of ANSYS program.The three-dimension contact element and the three-dimension equivalent heat conduction element is located in space between sliding layer and load-carrying layer.The surface of sliding layer of thrust bearing with Babbitt layer is smaller convex.The surface of sliding layer of thrust bearing with Teflon layer is concave. |
