FIELD: machine building.SUBSTANCE: centrifugal impeller contains drive disk (2) with blades (3) made together with hub (1), and covering disk (4) with central input hole (5). Disk (4) contacts with end faces (6) of blades (3). The blades (3) at side of their output edges (8) are provided with made together with blades (3) axial shanks (9). The shanks (9) protrudes beyond the rotation surface (7). On disk (3) going to the surface (7) the axial slots are made, in them shanks (9) are installed. In the impeller holes are madder corresponding to number of blades (3), each hole passes through the covering disk (2) at both sides of the slot and shank (9) located this slot. Pins are installed in holes.EFFECT: increased production effectiveness of centrifugal impeller, and extension of its scope of application.5 dwg |
