Zusammenfassung: | The invention discloses a contact type sealing assembly suitable for axial sealing of a rotor and a stator, and relates to the technical field of aero-engines, the contact type sealing assembly comprises the rotor and the stator which are matched with each other, the end faces of the sides, close to each other, of the rotor and the stator are provided with sealing pieces which are matched with each other respectively, the sealing pieces are attached to each other, and sealing rings are arranged in the sealing pieces respectively. The sealing pieces are respectively and radially sealed with the rotor and the stator through sealing rings; one side of the sealing piece is connected with a pre-tightening spring which abuts against a supporting component of the stator. According to the invention, the structural configuration with high efficiency, low cost and strict axial sealing requirements can be realized, the design requirements of the aero-engine are met, the performance of the original design state of the en |
