Stator vane mounting assembly for a compressor of a gas turbine

摘要

A compressor stator vane assemblage includes a first metal bushing (62) disposed within a bore (44) through the compressor casing (42) and bolted to the casing by externally accessible bolts (74). A second composite bushing (64) is disposed within the first bushing (62) and receives the spindle (52) of the stator vane (40). Reduced diameter portions (54,56) of the spindle project through openings in the first and second bushings (62,64). A lever (98) is attached to the spindle portion (54) and is movable to rotate the vane (40). By removing the bolts (74), the first and second bushings (62,64) can be removed from the casing (42) for replacement or rotation of 180 DEG for prolonged service life without disassembly of the casing (42) or removal of the stator vane (40).
