Tool for installing turbine generator stator wedges

Abstract

A process for installing a stator slide under a stator wedge in a radially oriented slot of a stator core assembly includes: a) loading windings in the radial slot, the radial slot having axially extending dovetail grooves in opposing sidewalls thereof; b) loading at least one stator wedge and stator slide in the dovetail grooves of the slot, and tightening the at least one stator wedge with the stator slide; c) loading at least one additional stator wedge in the dovetail grooves; d) locating at least one additional stator wedge slide relatively loosely under the additional stator wedge: and e) using the at least one stator wedge as a force reaction point, applying a force to the additional stator slide to drive the additional stator slide under the additional stator wedge. The tool for driving the stator slide under the stator wedge has a frame including a pair of elongated rail members; a force application cart located between the rail members, the force application cart having a force block thereon; a drive connected to the frame, substantially intermediate opposite ends of the frame; a lead screw threadably engaged at one end with the force application cart and connected at an opposite end to the drive such that the drive rotates the lead screw when actuated. Rotation of the lead screw causes axial movement of the force application cart and the force block against the slide in a tightening direction. A pin locates the tool relative to the stator slide, and establishes a reaction point for forces applied by the drive block to the stator slide.
