Abstract:
A centrifugal projecting machine having a house, a driving device disposed at a first side of the housing with a flange, an impeller having a plurality of blades, wherein the impeller is connected to a driving shaft of the driving device with a hub, a distributor disposed in an inner cylindrical space of the impeller so that it is concentrically arranged in relation to the driving shaft, wherein the distributor has slit-like openings that are circumferentially disposed with substantially equal clearances, a control cage having an opening around a distal end for dispersing shot, wherein a proximal end surface of the control cage is connected to the second side of the housing, opposite its first side, around an opening for an intake disposed at its second side, wherein he control cage is disposed with a clearance between inner ends of the blades and an outer surface of the distributor and extends over the length of the impeller, and a nozzle connected to the second side of the housing to supply the opening for an intake with shot, wherein a supporting member is disposed at the side of the impeller to support the rotating impeller, or a rotating member for sealing is disposed between the proximal end of the distributor and the distal end of the control cage, or a bearing is disposed at the clearance between the inner periphery of the flange and an outer periphery of a hub together with damping members.
