FITTING OF BLADES IN HYDRODYNAMIC MACHINES

摘要

A process of manufacturing a component for a hydrodynamic machine in which the component comprises a base body (16) and a plurality of blades (8) which are to be installed on the base body (16). The process comprises the steps of installing the plurality of blades (8) on the base body (16) by a shaped fitted connection with the base body (16) by applying continuous pressure against the base body (16) and using a prefabricated torus as the base body (16). The prefabricated torus is pressed by a pressure roller (20) against the plurality of blades (8) while holding the plurality of blades (8) in a device (4) against the pressure of the pressure roller (20). A component for a hydrodynamic machine, comprising a base body (16) and a plurality blades (8) installed by the inventive process, is also disclosed.
