Document Type and Number:
WIPO Patent Application WO/2021/227443
Kind Code:
A1
Abstract:
A connecting member and an anti-thermal mismatch connecting device. A rod portion (24) of a connecting member (2) comprises a material-reducing hollow segment (21) and a cylindrical segment (22), the material-reducing hollow segment (21) consists of a central shaft (211), a plurality of supporting rib plates (212) extending outwards from the outer peripheral surface of the central shaft (211) and radially inclined relative to the central shaft (211), and a plurality of outer ring plates (213) arranged around the central shaft, and a circumferential gap (214) is provided between adjacent outer ring plates. The supporting rib plates (212) are connected to the central shaft (211) and the outer ring plates (213), and the central shaft (211) is connected to the cylindrical segment (22). During actual use, the anti-thermal mismatch connecting device can relieve the problem of thermal deformation mismatch of a connection mounting structure between a CMC turbine outer ring member and a metal interlayer casing in various directions.
