Abstract

A method for mounting laminated sheets onto a shaft of a rotor provided for an electrical machine may involve sliding the laminated sheets onto the shaft and bracing the laminated sheets between two rotation-resistant thrust washers connected with the shaft. The laminated sheets may be slid onto the shaft to lie against a stop in the form of a first thrust washer arranged upon a first subsection of the shaft. A second thrust washer may be pressed in by axially bracing the laminated sheets onto a second axial subsection of the shaft in a frictional interlocking manner. The second thrust washer may be positioned after a surface of the second subsection has been enlarged by the introduction of an exterior surface profile.
