Abstract

A guide disc segment for a horizontally split turbomachine housing is provided. The guide disc segment includes a plurality of guide blades and an outer ring segment. The guide blades are fixed to the outer ring segment along an inner circumference. The outer ring segment can be rolled into or out of a guide blade carrier of the turbomachine housing. The outer ring segment has, along an outer circumference, a toothing into which a drive device engages. A tangential force can be applied to the outer ring segment by the toothing such that the guide disc segment can be driven during the rolling into or rolling out of the outer ring segment.
