FIXTURE AND METHOD FOR INSTALLING TURBINE BUCKETS

摘要

PROBLEM TO BE SOLVED: To provide a fixture and method for installing turbine buckets.SOLUTION: A fixture 100 for installing turbine buckets is adapted for mounting a plurality of turbine buckets with dovetails 112 to a rotor wheel of a turbomachine that is separated from an adjacent rotor wheel by a spacer wheel, the rotor wheel and the spacer wheel having a plurality of circumferentially aligned dovetail slots. The fixture 100 includes: a turbine bucket holder 110 having a dovetail 112 that is configured to engage with one of the dovetail slots of the spacer wheel. The profile of a bucket holder dovetail slot 118 substantially aligns the dovetail 112 of the turbine bucket with a dovetail slot of the rotor wheel for at least partial transfer of the turbine bucket to the rotor wheel.SELECTED DRAWING: Figure 2
