Abstract
Aspects of the invention relate to a system for reducing relative movement between the outer shroud of a compressor diaphragm and the compressor shell of a turbine engine, thereby minimizing the wear and prolonging the life of such parts. Embodiments of the invention include a system for applying a preload on the outer shroud of a compressor diaphragm. The preload can be applied in the axial and/or radial directions. The preload can be applied at or proximate the joint between two shell segments, which is typically the location of the largest relative movement. In one embodiment, the preload can be achieved by providing one or more load applying members that operatively engage the outer shroud. A load applying member according to aspects of the invention includes a first portion, a second portion, and a biasing member operatively positioned therebetween. The biasing member can be a plurality of spring washers.
