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