Abstract

A rotatable body (300, 400) includes a rotor (300) and n buckets (400), 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 (412) for engaging with the unified annular dovetail tenon (R) 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; assembling the nth bucket with the adapter (320); 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.
