Abstract (en)
[origin: CN105697395A] The invention relates to a rotor assembly for a vacuum pump and especially for a turbomolecular pump. The rotor assembly comprises a rotor shaft and at least on rotor disk. The rotor disk comprises an accomodating opening for accomodating the center of the rotor shaft. The rotor disk is arranged on the rotor shaft. A mechanical connection is built between the rotor disk and the rotor shaft. The rotor assembly is characterized in that mechanical connection is achieved through a heat joint method.
