Radial turbine wheel for blower has laminated air scoops to control vibration in operation

摘要

The radial blower wheel has a wheel body (1) with multiple scoops (5) and front (6) and rear (3) cover plates. The scoops are made of multiple layers (A-C) which at least in the area of the resonant frequency produce a damping of the torsional vibration induced bending vibration. The scoops can be made of three layers.
