Bearing ring for the storage of blade roots of variable stator vanes in the high-pressure compressor of a gas turbine

摘要

The present invention relates to a bearing ring for the storage of blade roots 1 of variable stator vanes 2 in the high-pressure compressor of a gas turbine, with a front 3 and a rear 4 annular body, which in each case to form an essentially u - shaped cross section has an axially open annular space 5, as well as a plurality of axial bores 6, characterized in that, in the opening area of the annular space 5 an annular cover 7 is arranged, which is provided with installation recesses 8, and that in the intermediate region between the assembly recess 8 of the covering body 7 and the associated mounting hole 5 of the base body 3, 4 is arranged a tubular support 9.
