Abstract
A rotatable body includes a rotor and n buckets, each bucket being coupled to the rotor in a tangential entry manner. The rotor supports each of the n buckets coupled to the rotor, so the buckets may be stably coupled to the rotor, using a unified annular dovetail tenon that protrudes axially from the rotor. Each bucket includes a bucket dovetail mortise for engaging with the unified annular dovetail tenon in order to couple the bucket to the rotor. A method of manufacturing the rotatable body includes assembling first to (n−1)th buckets with the rotor wheel by successively inserting the first to (n−1)th buckets through the tangential entry; assembling the nth bucket with the adapter; assembling the adapter with the rotor wheel, by inserting the adapter assembled with the nth bucket into the tangential entry; and collectively moving all the buckets by one half pitch in the circumferential direction.
