Abstract
Steam turbine buckets have radially projecting tenons received in openings of covers. The covers are provided with a profiled surface, with recesses or radially outwardly projecting teeth, or both, to form a gap between the cover and a stationary component having increased pressure drop with resulting decreased leakage flow and reduced potential for solid particle erosion. In the profiled cover surface, the outer surface of the tenon and outer surface of the cover are machined to form the recesses or teeth, affording a flush cover/tenon design with improved sealing efficiencies and reduced solid particle erosion.
