Abstract
A unison ring for adjusting the nozzle vanes in a split shaft gas turbine is mounted via a secondary ring attached to and encircling the casing. The secondary ring is mounted so as to accommodate dimensional variations in the housing due to temperature changes without altering the freely movable mounting engagement of the unison ring. The unison ring can thus be easily adjusted regardless of the variations in radial dimension between the housing and the unison ring.
