<p>The present invention comprises an inner diameter vane shroud (14) that accommodates a mechanism for synchronously rotating an array of variable vanes (26,28). Particularly, the invention comprises an inner diameter vane shroud (14) that has a gear channel (40A,40B) that runs circumferentially through the vane shroud (14). An array of variable vanes (26,28) is rotatably mounted in the vane shroud (14) at an inner end. The variable vanes comprise vane gears (34) at their inner end, which are rotatable in the gear channel (40A,40B). Disposed between the vane gears (34) of the variable vanes are idler gears (36). As one of the individual variable vanes is rotated by an actuation source, the other variable vanes of the variable vane array are rotated a like amount by the vane gears (34) and idler gears (36).</p> |
