Document Type and Number:
Japanese Patent JP7256282
Kind Code:
B2
Abstract:
In order to alleviate a mismatch problem of thermal deformation, in all directions, of a connecting and installing structure between a CMC turbine outer annular component and a metal intermediate casing, a connector and an anti thermal mismatch connecting device are provided. The rod part of the connector comprises a subtractive hollow section and a cylindrical section. The subtractive hollow section is composed of a central shaft, a plurality of supporting rib plates extending outwards from a peripheral surface of the central shaft and inclined radially relative to the central shaft, and a plurality of outer annular plates arranged around the central shaft, with a circumferential gap between adjacent outer annular plates. The central shaft and the outer annular plate are connected by the supporting rib plate, and the central shaft is connected with the cylindrical section. The anti thermal mismatch connecting device comprises the connector.
