Impeller for a radial-flow fan

摘要

An impeller for a radial-flow fan is proposed, having a hub body (2) arranged on a shaft (1), a multiplicity of moving blades (3) and a cover disc (4), and also a base disc (5), the hub body (2), moving blades (3) and cover disc (4) consisting of a one-piece, axially demouldable first cast component. The base disc (5) consists of an axially demouldable second cast component and is fastened to the shaft (1) and/or the hub body (2) by means of a push-in connection which can be fitted together axially. This permits simple manufacture in conjunction with a fluidically advantageous configuration of the impeller.
