PROBLEM TO BE SOLVED: To provide a thrust bearing equipped with a thrust sector in which the number of metal molds can be reduced, the accuracy of heating and pressurizing can be improved and heating time and cooling time can be shortened when the thrust sector is manufactured, and provide a dynamo-electric machine equipped with this thrust bearing. SOLUTION: A teflon board formed by baking a tetrafluoroethylene resin layer (teflon layer) on the surface of a thin steel plate, is cut into a required shap so as to prepare a teflon pad 6A, and this teflon pad 6A is fixed on a thrust sector base metal 7A formed into a required shape so as to form a thrust sector 10A, then this thrust sector 10A is arranged on a thrust bearing. The teflon pad 6A is fixed by fitting slant surfaces 6A-3 on both circumferential sides of the teflon pad 6A to grooves 7A-1 formed on both circumferential sides of the thrust sector base metal 7A. |
