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.

Wear minimization system for a compressor diaphragm

A wear determination device for determining vibration in a turbine engine component to reduce wear in a turbine engine. The wear determination device may be capable of measuring vibrations in a turbine engine component. The vibration measurement may be used to determine vibrations in a turbine engine to identify wear locations and sources of wear. The wear determination device may be configured such that multiple locations in a turbine engine may be monitored on a single turbine engine by moving the wear determination device from location to location.

Wear monitor for turbo-machine

A stator ( &prime;) for a power generator having a coil support finger plate ( &prime;) and associated methods are provided. The stator ( &prime;) preferably has a plurality of laminations or step irons having a plurality of spaced-apart stator coil slots ( &prime;) formed therein and stator coil slot contents ( ) positioned in each of the plurality of stator coil slots ( &prime;). The stator coil slot contents ( ) preferably include at least one stator coil ( ). The stator ( &prime;) also preferably has a coil support finger plate ( &prime;) positioned at an end portion of the plurality of stator coil slots ( &prime;). The coil support finger plate ( &prime;) has a base ( &prime;) and a plurality of fingers ( ) extending outwardly from the base ( &prime;) between the plurality of spaced-apart stator coil slots ( &prime;). The base ( &prime;) includes a stator slot contents support portion ( ) positioned to underlie end portions of the stator slot contents ( ) and to support the end portions of the stator coil slot contents ( ) thereon so that the stator slot contents support portion ( ) defines a stator slot bottom at the coil support finger plate ( &prime;).
