| Zusammenfassung: | The invention discloses an integral ceramic-based turbine outer ring positioning structure which comprises a metal ring set, a ceramic-based turbine outer ring and an elastic sealing adjusting assembly, wherein the ceramic-based turbine outer ring and the elastic sealing adjusting assembly are arranged in an inner ring cavity of the metal ring set. The first end of the ceramic-based turbine outer ring abuts against the first end of the metal ring set to form a conical face matching structure, the second end of the ceramic-based turbine outer ring abuts against the elastic sealing adjusting assembly, and the other end, opposite to the elastic sealing adjusting assembly, of the ceramic-based turbine outer ring abuts against the second end of the metal ring set. The positioning structure is used for converting radial extrusion generated by thermal deformation of the ceramic-based turbine outer ring and the metal ring set into axial displacement of the ceramic-based turbine outer ring through the conical surface |
