BLADE FOR CENTRIFUGAL SHOT-BLASTING TURBINE MACHINE AND METHOD OF SERVICING CENTRIFUGAL SHOT BLASTING TURBINE MACHINE Russian patent published in 2019 - IPC B24C5/06 

FIELD: machine building.

SUBSTANCE: invention relates to centrifugal shot-blasting turbine machine. Proposed machine comprises housing and impeller assembly attached to housing. Impeller assembly comprises a first wheel disc with a first side and a first plurality of grooves on the first side and a plurality of blades configured to eject an abrasive introduced into the impeller assembly onto the workpiece. Each blade comprises an upper surface for receiving abrasive material, a curvilinear portion adjacent to the impeller assembly central hub, rectilinear section made integral with the curvilinear section and extending radially outward from the impeller unit, and the first lateral guide extending along the blade. First lateral guide has first recess wherein first gasket is arranged. Each groove is made with possibility to accommodate corresponding blade fixed in place by press fit between the first side of the first disk of the impeller and the first gasket of the corresponding blade.

EFFECT: result is reduced abrasive wear of blades.
