摘要： The steampath for a steam turbine includes stacked stator rings 12 each mounting inwardly directed nozzles 14 and stacked rotor wheels 16 each mounting outwardly directed buckets 60 mounting blades. By alternately stacking the stator rings and rotor wheels, the nozzles and buckets of the various stages are interdigitated to form a steampath. Each bucket includes a blade and a root 61 received in a generally complementary shaped groove on a wheel.
