Systems and methods for manufacturing a shrouded impeller

摘要

Multipart shrouded impellers and methods for manufacturing multi-part shrouded impellers are described. Components of the shrouded impeller include alignment features that, when brought into contact, provide concentric and spatial alignment of the component parts. Upon alignment a gap remains between portions of the components, which permits the introduction of a filler material that joins the components into a unitized whole.

主权项

1. An intermediary two-part shrouded impeller, comprising:
a first machined component having a first major surface, a first impeller blade extending from the first major surface and having a first apical surface, a second impeller blade extending from the first major surface and having a second apical surface, a third impeller blade extending from the first major surface and having a third apical surface, and a circumferential step on the first major surface surrounding the first impeller blade, second impeller blade, and third impeller blade; a second machined component having a first major surface and two or more legs extending therefrom; wherein the first component and the second component are configured such that contacting the two or more legs of the second machined component with the circumferential step of the first machined component leaves a gap between the first apical surface and the first major surface of the second component.
