Method for fixedly connecting turbine wheel with shaft of turbo supercharger of combustion engine, involves connecting recess limiting wall with component and with imported connection section of another component

摘要

The method involves connecting a recess limiting wall with a component and with an imported connection section (14) of another component by creation of a magnetic field. The connection section embracing the component is radially shrunk by the creation of the magnetic field in an electromagnetic transforming path for creation of clamping force. A ring or a cap is placed around the connection section, where diameter of the ring or the cap in the electromagnetic transforming path is permanently reduced. An independent claim is also included for a turbo supercharger comprising a compressor.
