摘要: A fabricated centrifugal impeller assembly is provided which resists failure due to cyclic stressing. The includes a hub, and plurality of blades. Each blade has tab adjacent its axis rotation, with the extending generally perpendicularly radially main portion blade. retainer positioned back surface hub clamp tabs between hub. slots that permit insertion therethrough each in abutting contact retainer. Compression means connect exert compressive force clamps against attaching separate blades an manner does not disrupt flow contours inlet area.
