The invention relates to a wheel for centrifugal jet machines with two rotating wheel discs, a plurality of centrifugal blades distributed evenly around the periphery, each blade being provided with lateral ribs or strips, the blades being insertable from the inside into radial grooves in the wheel discs and held therein by fixed stops. According to the invention, the length of the lateral strips is shorter than the diameter of the central free space of the wheel formed by the inside ends of the blades. Moreover, the width of the part of each centrifugal blade projecting beyond the lateral strips is smaller than the distance between the two discs. As a result of this dimensional relationship, the centrifugal blade can be inserted from the outside between the wheel discs in a position twisted in relation to the centrifugal axis until the lateral strips are in the central, free space and then are moved radially outwardly to a fixed stop from the inside in the grooves of the wheel discs, as a result of which centrifugal blades of any arbitrary length may be used. |
