Method for generating rotational torque transferring connection between outer surface of rotor shaft and inner surface of hole, involves pressing shaft outer surface by expanding diameter of shaft or reducing diameter of hole

摘要

The method involves applying friction paint (10) on either of the outer surface of the shaft (2) or inner surface of the hole (4). The outer surface of the shaft is moved relative to the inner surface of the hole in direction parallel to the symmetry axis of the shaft until outer surface and the inner surface in radial direction (8) vertical to the axial direction (12). The diameter of the shaft is expanded or diameter of the hole is reduced, so that the outer surface of the shaft in the radial direction is pressed against the inner surface of the hole. An independent claim is included for rotational-torque transferring arrangement.
