Abstract

A guide vane ring which is divided into an upper and into a lower guide vane ring half, with an inner ring which is split at least in two, has a substantially U-shaped cross section, and forms a radially outwardly open flow duct which extends in the circumferential direction and is delimited by way of an inner ring bottom wall and two inner ring side walls, and with a multiplicity of vane platforms which receive guide vanes, are arranged along the outer circumference of the inner ring, and have holding webs which in each case project radially inwards, are spaced apart from one another in the axial direction, and engage around the inner ring side walls from the outside, wherein wear elements are inserted into gaps which are present between holding webs and directly adjacently arranged inner ring side walls.
